–7–


Voltage Reduction: Three independent steps, each adjustable from 0% to 10% in 0.1% increments of thebandcenter setpoint.

Inhibit of Auto Tapchange: Blocks automatic tapchanger operation in response to external contact closure orsoftware setting.

Sequential or Non-Sequential Operation: Non-sequential operation resets the time delay upon momentaryexternal contact closure at the non-sequential input.

Paralleling Methods:

Circulating Current: The circulating current method is standard, and may be implemented using separatebalancing equipment such as the Beckwith Electric M-0115A Parallel Balancing Module. Consult with factory foruse with existing external master-follower circuitry.

ΔΔΔΔΔVAR™: When specified, the ΔVAR1 method may be implemented by using separate balancing equipment suchas the M-0115A Balancing Module. The ΔVAR2 method does not require the use of the M-0115A BalancingModule and is only applicable when paralleling two transformers.

For all methods of paralleling except ΔVAR2, overcurrent protection, such as that provided by the M-0127AOvercurrent Relay, is recommended.

VT Ratio Correction: VT correction from –15 V to +15 V in 0.1 V increments.

Self-Test Alarm Output Contacts: Alerts operator to loss of power or malfunction of control. When the control isconfigured for SCAMP Pushbutton Auto/Manual Switch Type, this output is not available.

User-Programmable Alarm Contacts: Alerts operator to one or more of the following system conditions:Communications Block Invoked, Block Raise Voltage Limit Exceeded, Block Lower Voltage Limit Exceeded,Voltage Reduction (any step) Invoked, Reverse Power Flow Condition Detected, Line Current Limit Exceeded,Tap Block Raise in Effect, and Tap Block Lower in Effect.

Tap Position KnowledgeTransformer LTC: The optional M-2025B Current Loop Interface Module receives a signal from a positiontransducer and outputs to the M-2001C through a bottom port.

Single-Phase Regulators: In most applications, tap position information can be maintained by means of aninternal "keep track" logic.

Operations Counter: A software counter increments by one count per either an open/close/open contactoperation (X1) or an open/close or close/open contact operation (X2), and is preset by the user. A count windowmode registers any activity as a valid input within the count window time setting.

Resettable Operations Counter: A second software counter, similar to the operations counter, which may bereset by the user.

Harmonic Analysis: Provides the total harmonic distortion and the harmonic content of the load voltage andcurrent up to the 31st harmonic (using TapTalk with BECO 2200 protocol).

Tap Position Record: Provides a record of the number of times each tap position has been passed through(using TapTalk with BECO 2200 protocol). The tap position record can be reset by the user.

AUTO/MANUAL Switch Status: Provides the user with the Auto/Manual switch position status through theComm ports. When the M-2001C is configured for a switch status input, the switch status is read using the seal-in input on the control. When configured for Seal-in INPUT, the switch status is read using the counter INPUT.

A or B Regulator Type: Allows the user to select the type of regulator being used to provide a more accuratesource voltage calculation.

InputsControl Voltage Input: Nominal 120 V ac, 60 Hz (50 Hz optional); operates properly from 90 V ac to 140 V ac.If set at 60 Hz, the operating system frequency is from 55 to 65 Hz; if set at 50 Hz, the operating systemfrequency is from 45 to 55 Hz. The burden imposed on the input is 8 VA or less. The unit should be poweredfrom a voltage transformer connected at the controlled voltage bus. The unit will withstand twice the voltageinput for one second and four times the voltage input for one cycle.

Motor Power Input: Nominal 120 V ac to 240 V ac, at up to 6 A as required by the load, with no wiring changesrequired.

–8–


Line Current Input: Line drop compensation is provided by a current transformer input with a 0.2 A full scalerating. A Beckwith Electric model M-0121 (5 A to 0.2 A) or M-0169A (5 A or 8.66 A to 0.2 A) Auxiliary CurrentTransformer is available when required. The burden imposed on the current source is 0.03 VA or less at 200 mA.The input will withstand 400 mA for two hours and 4 A for 1 second.

Circulating Current Input: Parallel operation of regulators or transformers is accommodated by a currenttransformer input with a 0.2 A full scale rating. The burden imposed on the current source is 0.03 VA or less at200 mA. The input will withstand 400 mA for two hours and 4 A for 1 second.

Control Power Backup Input (Six pin Molex connector on the left side bottom of control): The optional ControlPower Backup Input feature sustains operation of the control in the event of a loss of AC input power to thecontrol. Raise and Lower commands are possible if the control's motor power remains energized. When thisfeature is enabled the Tap Position Knowledge by Current Loop feature is unavailable. See M-2026/M2027Companion Control Power Backup Supplies (page 14).

Binary InputsVoltage Reduction 1 & 2 Inputs: These inputs provide three levels of programmable voltage reduction whichcan be manually invoked.

Neutral Position Detect: The Neutral Position Detect Input detects the neutral tap position, which assists the"keep track" tap position function. This Neutral Position Detect Input also facilitates disabling the parallelingmode Delta Var2.

Counter Input/Switch Status Input: When Input Selection 1 configuration is set to Switch Status, the CounterInput detects tap position changes and updates two counters, one pre-settable and one re-settable. When InputSelection 1 configuration is set to Seal-In, the counter input is used as the Switch Status Input and the Seal-Ininput will cause the counter to increment.

Seal-in/Switch Status Input: When the Input Selection 1 configuration is set to "seal-in input", this inputprovides for detection of the seal-in state to operate the seal-in output and will also increment the counters. When"Input Selection 1" is set to Swtich Status Input, this input provides the means to read the Auto/Manual switchposition status using SCADA.

Non-Sequential/SCADA Cutout Input: When the Input Selection 2 configuration is set to "Nonseq Input", thisinput provides the means to perform non-sequential operations. When Input Selection 2 is set to "SCADA CutoutInput", this input provides a means to block all write operations to the control from SCADA.

OutputsRaise Output: Capable of switching 6 A at 120 Vac to 240 V ac motor power.

Lower Output: Capable of switching 6 A at 120 Vac to 240 V ac motor power.

Seal-In Output: Connects to the B-0553 motor seal-in printed circuit board subassembly.

Application: Using a PC, the operator has real-time, remote access to all functions of the M-2001C DigitalTapchanger Control. The control can act as the monitoring point for all voltage, current, and related powerquantities, thereby simplifying operation while avoiding transducers and multiple Remote Terminal Unit (RTU)analog inputs. The protocols implement half-duplex, two-way communications. This allows all functions, whichwould otherwise require the presence of an operator at the control, to be performed remotely. Communicationcapabilities include:

• Interrogation and modification of setpoints

• Broadcast of commands, such as tap change inhibit and voltage reduction (up to three steps) tonetworked controls

• Recognition of alarm conditions, such as voltage extremes and excessive load

• Selective control of raise and lower tap change operations

• Re-configuration of the control, such as a change to the demand integration time period or a selectionof different alarm parameters

Unit Identifier: A 2-row by 15-character alphanumeric sequence, set by the user, can be used for unitidentification.

EnvironmentalTemperature: Control operates from –40° C to + 85° C with either the LCD or Vacuum Fluorescent display.

■ NOTE: The LCD display's functional temperature range is –20° C to +70° C. The optional Vacuum Fluorescentdisplay's functional temperature range is –40° C to +80° C.

The resultant voltage signal is conditioned in theM-2025B(C) and routed to the M-2001 series Tapchanger Control where the voltage is converted to a correspondingtap position number.

The tap position sensors are rotary shaft encoders with built-in microprocessors that provide stepped outputsignals in 9 or 10 degree increments. They have rotations of 288 and 320 degrees respectively for 32 taps andone neutral position. The electrical output of these sensors is a 4-20 mA current loop that converts easliy to avoltage signal at the input of the M-2025B(C) with the addition of a proper value shunt resistor. For a 4-20 MACurrent Loop, 150 ohms is required on the input of the M-2025B(C).

ConfigurationsMost LTC tapchangers have an output shaft on the tapchanger mechanism whose angular position is amechanical analog of the tapchanger tap position. In many cases, the total range of tap positions is representedby less than one complete rotation of this position output shaft. The typical values of shaft movement on 32 tapmechanisms are 90 or 100 of mechanical rotation per tap position.

Other angular rotation values are likely to be encountered. Contact Beckwith Electric for information on sensoravailability for specific requirements.

1.0 Description

The M-2001C (BASE-R) Digital Tapchanger Controlis a microcontroller-based transformer and step-voltage regulator load tapchanger control.

The control is normally supplied with a separateadapter panel that is designed for initial OEMinstallation on new transformers or to replace aparticular manufacturer’s tapchanger control. Thepanel is designed to mechanically and electricallyreplace an old control, with matching mountinghardware to facilitate the replacement. See Figure1-2, Typical Adapter Panel Mounting.

Interrogation of the control and setting changes aremade through the user interface (HMI), or throughthe communications port (COM2.) User interfaceconsists of a 20-character by 2-line display and fourpushbuttons. Two passwords available to the userare accessed by the buttons and a third is accessedthrough the communications port. All setpoints arestored in non-volatile memory which is unaffectedby control voltage disturbances.

Two operation counters are provided. One countermay be reset; the other may be pre-set by the user.

Eight LEDs are used to indicate Tapchanger Raiseand Lower command status, Reverse Powerdetection, CPU OK, LDC In Effect, V/RED Voltage

Reduction in Effect, MANUAL Control (AutoOperation Blocked Via Comm or Front Panel), LOCAL(SCADA Control Blocked Locally) and COM1 TXand RX. The LOCAL and COM1 TX/RX LEDs arenot functional on the BASE-R control.

The control uses a Motorola microcontroller whichhas a self-testing watchdog system. Refer to Figure1-1 for the functional diagram. The alphanumericdisplay and four-button interface provides completefront panel access to the scrolling menu programshown in the Appendix, Figure A-1. The controlapplies to tapchanger designs with manyconfigurations of taps (e.g., 16 taps,1 to 17 taps,0 to 33 taps, etc.).

1.1 Adapter Panel/Surface Mounting Kit

An adapter panel or an M-2050 or M-2054 SurfaceMounting Kit must be used with the M-2001CTapchanger Control. Each panel adapts the M-2001Cas a transformer and regulator control replacementand provides the external connections necessaryfor operation via terminal blocks on the rear of theadapter panel. Contact Beckwith Electric for a list ofadapter panels that are currently available. Refer tothe Application Guides of the specific adapter panelfor the mounting details. See Figure 1-2 for a typicaladapter panel mounting.

The M-2050 is an adapter kit which permits surfacemounting of the control using two right angle mountingbrackets, four screws and a 24-pin connector withsix-foot pigtails on each pin. The M-2050 does notinclude features available on adapter panels. Thesefeatures include mechanical configurations and wiringconnections for direct replacement, CT shorting orfront panel switches, fuses or test points. Refer tothe Instruction Manual of the M-2050 for the mountingdetails.

The M-2054 is an adapter kit which permits surfacemounting of the control using two right angle mountingbrackets, four screws and a 24-pin connector withsix-foot pigtails on each pin. Refer to the InstructionManual of the M-2054 for the mounting details andadditional information.

1.2 Accessories

M-2029A TapTalk® Communications SoftwareTapTalk is a Windows-based communicationssoftware program available for remote control andmetering of the M-2001C (BASE-R) TapchangerControl. It is designed to interface with the

microcontroller of the control through an RS-232port (COM2.) The RS-232 port supports baud ratesup to 19200 bps. The M-2029A software displays allpertinent operating information. All operations thatcan be performed from the front panel user interfaceof the control can be duplicated remotely, throughM-2029A. These operations include:

• Changing setpoint values. (This includesthose values for normal tapchanger controloperation, as well as custom configurationto the site.)

• Observing values. (This includesmeasured and calculated values of real-time operating parameters.)

• Data logging. The control can internallystore various parameters at selectedintervals. The M-2029A program candownload this data into an Excel®spreadsheet and display. Alternatively, thePC can be programmed to poll the controland obtain a pre-selected list of parametersat selected intervals.

2.3 Status Indicators ........................................................................ 2–2

Screen BlankingThe display automatically goes blank after exitingfrom any menu, or from any screen after 15 minutesof unattended operation. Manual screen blanking isaccomplished by pressing the EXIT pushbutton.

Flashing C “CHANGE” PromptThis prompt, in the bottom right corner of a screen,is enabled by initially pressing ENT. This promptindicates that the user can change a setting usingthe r or ooooo pushbuttons to increment or decrementthe settings. Values have factory preset increments,such as 0.1 volt or 1 second. Press ENT the secondtime to execute the setting change.

“ENT” PromptWhen the “E” prompt appears in the top right cornerof the drag-hand parameter screens, operationcounter reset screen, and demand metering screen,it indicates that the value of display will reset if theENT pushbutton is pressed.

2.0 Introduction

The front-panel user interface consists of a standardLiquid Crystal Display (LCD) or optional VacuumFluorescent Display (VFD), r, ooooo, EXIT, and ENTpushbuttons, status indicators,and the controlswitches as shown in Figure 2-1, M-2001C (BASE-R) Front Panel.

2.1 Display/Tapchanger Control

The display shows the desired function and its currentstatus or setpoint value. The function is displayed onthe top line, and the bottom line displays its currentstatus. The display is normally blank and remains sountil the r, ooooo, or ENT pushbutton is depressed.Pressing any pushbutton will display the User Linesscreen, and then the Local Voltage screen.

Power Up Screens

Each time the control is powered up, it will brieflydisplay a series of screens that include:

• Beckwith Electric M-2001C (BASE-R)

• Serial Number

• Control Firmware Number

• Date

• Time of Day

• User Lines

2–2


2.2 User Interface Controls

rrrrr and o PushbuttonsThe r and ooooo pushbuttons have two functions.First, they are used to change screens and scrollthrough selections. Second, they are used to enternew values by incrementing or decrementing thedisplayed value. The new value is not stored untilthe ENT pushbutton is pressed a second time.

Pressing the r or ooooo pushbutton for longer than onesecond will cause faster scrolling, either whenselecting screens or when selecting setpoint values.

ENT PushbuttonThe ENT pushbutton is used to perform the followingfunctions:

• Enter the change mode of a screen• Store a setpoint or condition in

memory• Enter an access code• Reset certain status screens

When entering an access code, the ENT pushbuttonwill move the cursor (an underline) to the selecteddigit location and the rrrrr or ooooo pushbutton will changethe value. When the final digit is selected, and “C”is flashing, the new access code is entered usingthe ENT pushbutton.

In some cases, it is desirable to leave a screenwithout making a change. In selecting setpoints orsettings, wait 20 seconds without pressing the ENTpushbutton and the “C” will stop flashing. At thatpoint, the rrrrr and ooooo pushbuttons will again changescreens rather than scroll the previous setpointnumber or setting choice. The previous changes ofthat screen will not be recorded and the oldersetpoints or configuration choices will still be ineffect.

When setting passwords, programmable alarmfunction or user lines in the Configuration Menu, the20-second time-out is not functional and the usercannot cancel once a new entry has been started.

EXIT PushbuttonThe EXIT pushbutton is used to exit from anyscreen, causing the display to go blank. If EXIT isselected while the "C" is flashing, the control willexit without keeping the changed setting.

2.3 Status Indicators

RAISE LEDThe red LED indicates when the voltage is below thelower band edge and the timer has started timing fora tapchanger raise operation.

LOWER LEDThe red LED indicates that the voltage is above theupper band edge and the timer has started timing fora tapchanger lower operation.

REV PWR LEDThe red LED will light to indicate when the unitdetects reverse power flow.

OK LEDThe green LED light will remain lit whenever poweris applied to the unit and the watchdog circuitindicates the microcontroller is working properly.

LDC LEDThe yellow LED will illuminate when any non-zerosetting has been entered as LDC Fwd resistance orreactance, or LDC-Z. It will also illuminate when anynon-zero setting has been entered as LDC Revresistance or reactance with the "Rev Power Oper"configuration set to "regulate in Reverse" and thecontrol in reverse power mode.

V/RED LEDThe yellow LED will illuminate when any level ofvoltage reduction has been invoked. This is true forany voltage reduction process whether it came froman external contact or any Com input.

MANUAL LEDThe yellow LED will illuminate when Auto Operationof the control has been blocked from any COM port.It will also illuminate when Manual Mode has beenselected using the Adapter Panel Auto/ManualPushbutton or toggle switch.

LOCAL LEDThis LED is not functional on the BASE-R version.

COM1 TX/RX LEDsThese LEDs are not functional on the BASE-Rversion.

3.0 Introduction

If the control will not execute Raise or Loweroperations due to remote blocking using M-2029ATapTalk®, front panel operation can be restored byusing the Remote Control screen to remove theblock, or momentarily removing power from thecontrol. In order to restore front panel operation, theSave Comm Block at Power Off configuration settingmust be set to Disable.

Local and remote control may be used at the sametime by designating “Local Mode” disabled in theConfiguration menu.

Settings EntryUse the rrrrr and ooooo pushbuttons to scroll to thedesired setpoint entry screen and press ENT toenter the change mode. A password is required forentry into change mode, unless the Level 1 passwordhas been disabled. Use the rrrrr, ooooo and ENTpushbuttons to change the setting.

When the control is first energized, the quickestway to properly initialize the control prior to enteringthe setpoints is to set the real-time clock. Thisaction will initiate a prompt from the control to

perform a reset operation for the following items:• Demand Metering

• Energy Metering

• Drag Hands Reset Registers


It is then easy to proceed with the remainder of thecontrol setup.

3.1 Passwords

Password Access ScreensTo prevent unauthorized access to the controlfunctions, there are provisions in the software forassigning up to three passwords. Two are for usewith the front panel controls and one is for use withthe communication interface. The passwords canbe set in the Configuration Menu. For moreinformation, refer to the Passwords section of theConfiguration chapter.

Access LevelsGeneral access to read setpoints, to monitor status,to reset drag-hand parameters and the resettableoperations counter do not require a password.


3–2

The Level 1 password, if set, is required to makelocal setting changes including the date and time ofday. If the Level 1 password is set to all zeros, thisrequest for a password will not be seen and changescan be made without a password.

The Level 2 password, if set, is required to makechanges to the configuration, passwords, and useridentification. If the Level 2 password is set to allzeros, this request for a password will not be seenand changes can be made without a password.

The COMM password is for use with the M-2029ATapTalk® Communications Software. This passwordprovides secure remote operation. If thecommunications password is set to all zeros in theM-2001C (BASE-R) Digital Tapchanger Control, thecommunications program will not ask for a password.

88888 WARNING: Please record all passwords in asecure location. If the password is lost orforgotten, please contact the factory.

3.2 Voltage Regulation

Standard Control SettingsRefer to the Appendix, Figure A-4. With the Level 1password, six forward and six reverse setpoints areavailable (see Table 3-1) from the Setpoint Menu.They are: bandcenter, bandwidth, time delay, inversetime, and line drop compensation resistance andreactance for each direction and Z-compensation.

The control will send commands to the tapchangerto change taps as needed to hold the voltagewithin the bandwidth setting as modified by theline drop compensation settings and by paralleling.

The control will only respond to an out-of-bandvoltage excursion after the timer has reached thetime delay setting. The timer can be set as anintegrating timer or an instantaneous reset timerupon the voltage return to an in-band condition. Asan integrating timer, it increments during time out-of-band and decrements during time in band, butnot below zero.

Voltage Regulation Without LDCWhen the control is just used to regulate the voltageon the transformer or regulator low-side bus, theonly input required is voltage from a line-to-line orline-to-ground VT with a nominal 120 V acsecondary.

Bandcenter (BC)The center of the voltage band is adjustable from100 to 135 V ac in 0.1 volt increments (for example,120 V ac).

Bandwidth (BW)The LTC uses discrete steps and the Bandwidthmust have a width that allows at least one tapchangeposition where the control remains satisfied. Tominimize excessive operations on the tapchanger,this bandwidth is usually set to include two or threein-band tap operation positions.

The range is settable from 1 to 10 volts in 0.1 voltincrements, and 2 volts minimum is recommended.This setting is the total bandwidth.

Time Delay (TD)The time delay setting is needed to inhibit thetapchanger from unnecessary operations ontemporary voltage excursions and is commonlyset at 30 to 60 seconds.

The control has two types of timers for time delay:definite time and inverse time. The kind of timedelay the control will use depends on the settingfound in the configuration menu called TIMERSELECTION. Both types of delay will work inforward or reverse power flow. The inverse timedelay will follow the curve in Figure 3-1, InverseTime Delay Curve.

Inverse Time Example

Bandwidth 3 V

Inverse Time Delay Setting 120 s

ΔV = (Bandwidth/2) = 1.5 V

Vin = 123 V

Voltage Regulation with LDCWhen it is desirable to regulate the voltage at somedistance from the transformer or voltage regulator,or in general to raise the voltage during high loadconditions, the Line Drop Compensation (LDC)feature is used.

Two different LDC methods are available in theM-2001C (BASE-R) Digital Tapchanger Control. Aconfiguration setpoint called LDC Selection allowsthe user to select from either of these methods.

The Bandcenter, Bandwidth, and Time Delayfunctions are set the same as if LDC were notused.

LDC X/RA classical approach can be used to determine theX/R settings for the LDC, however this assumes aload center point and is usually not applicable tothe typical distribution feeder. For more information,contact Beckwith Electric for Application Note#17.

A simpler method, which will work for mostapplications, is recommended. This involves lookingat the lines leaving the station and determining thereactance/resistance (X/R) ratio for the main line.The reactive and resistive line drop compensationsetpoints should then be entered in this same X/Rratio.

If the CT and VT phasing corrections have beenmade to remove any phase angles betweenmeasured voltage and live current, only positivevalues of R and X compensation need to be used.

Table 3-2 gives the X/R ratio for various wire sizesand typical conductor spacings.

By knowing the ratio of the maximum expectedload to the present load, the amount of voltagecompensation needed is found as shown in thefollowing example.

ExampleDesired

local voltage @ min load = 120 volts

local voltage @ max load = 124 volts

Using the following assumptions:Desired Bandcenter = 120 volts

Desired Bandwidth = 2 volts

The device being controlled is 50%loaded

SettingStart with R=0 and X=0 and increase both valuesusing the ratio shown in the table for the feederconductor. Keeping the X/R ratio, increase R

set and

Xset

until the difference between the compensatedvoltage and the local voltage is 2.0 volts.

This example would let the voltage vary from 119 Vat no load to 125 V at maximum load taking intoaccount the bandwidth.

With this simplified method of LDC setting, the firstcustomer’s voltage will be limited by the uppervoltage limit at the highest daily load, depending onthe accuracy of the daily load projection. At thesame time, the furthest customer will receive thehighest voltage possible under the line and loadingconditions. The first customer protection can be seton the control. Refer to the Regulation Limitssection of this chapter.

Since the daily load projections will likely have aseasonal variation, the best balance of first customerto furthest customer voltage may require seasonaladjustment of the LDC settings. Note that the settingsof R and X compensation are proportional to thepeak load projection and that new settings can bescaled from the first setting obtained by theexperimental process just described.

LDC-ZThe second available compensation method is calledZ-compensation (LDC-Z). LDC-Z must be selectedin the control configuration portion of the menu orsoftware and the VOLTAGE RAISE (V

R) setpoint

must be set in order for this feature to beimplemented. The LDC-Z application is especiallyuseful on systems where several lines exist withdifferent load centers where the proper compensationis not related to any single R & X values as set in R& X compensation.

Basically, LDC-Z compensation consists ofdesignating a target bus voltage increase (line dropcompensation) that correlates to the magnitude ofthe control current rather than to the calculation ofinput R & X line drop at control current magnitudeand angle values.

The setting, (VR), is the calculated line voltage drop

(at maximum load) in the circuit or line that has thehighest voltage drop at maximum load condition -ratio’d to the rated CT output (200 ma).

VR

= 0 to 24 volts in increments of 1 volt.

Example:• Calculated voltage drop = 5 volts at load

level of 150 ma control current.

• VR

setting = 200/150 X 5 = 6.7 volts(rounded) = 7 volts

To calculate the line drop compensation at anygiven control current level (I):

• V = I/200 X 7 (setting):

If I = 50 ma; V = 50/200 X 7 = 1.75 volts

As with R & X compensation applications, the “blockraise” and “deadband” settings are used for firsthouse protection on all circuits or lines.

■ NOTE: For additional information about LDC-Zapplications, contact Beckwith Electricto obtain Distributech Paper 1/27/05,"Maximizing Automatic Reverse PowerOperations with LTC Transformers andRegulators."

3.3 Voltage Reduction

Refer to the Appendix, Figure A-4. The controlallows three steps of voltage reduction via externaldry contacts or by serial port connection. Thepercentage voltage reduction at each step isadjustable from 0 to 10% in 0.1% increments. Whenone or more contacts are closed, the effect is toshift the bandcenter setpoint lower thus causing theLTC to lower the voltage.

Recognize that the “effective” bandcenter may havebeen raised by line drop compensator action whenthe voltage reduction is initiated and that the resultantvoltage setting will be the combination of the twoeffects. Note also that the undervoltage block settingmay limit the lowering of voltage, especially if thereis little raising of the local voltage due to LDCaction.

When first initiated, or when a subsequent step ofvoltage reduction is needed, the control will respondimmediately to the voltage reduction commandwithout regard to either the intertap time delay settingor the control time delay setting. After the desiredvoltage reduction, operation will revert back to normaloperation with the time delay. Refer to Section 6,Connections, for contact connections.

Wired SCADA dry contacts or serial port connectioncan be used to provide stepped voltage reduction asdescribed earlier. However, these should not beused together, since the resulting reduction wouldbe the combination of the inputs.

3.4 Regulation Limits

Overvoltage Limit & Voltage RunbackRefer to the Appendix, Figure A-4. Setpoints areavailable to establish a block raise limit and voltagerunback. The overvoltage limit is adjustable from95.0 V to 135.0 V in 0.1 V increments. Theovervoltage limit must be set above the upper controlband limit. This limit is one portion of the FirstCustomer Protector to limit overvoltage from linedrop compensation action during heavy loading.

The voltage runback level is the Block Raise settingplus the Dead Band setting (this establishes theFirst Customer Protection level.) This deadbandshould not be confused with the control deadbandabove and below the center voltage setpoint, whichis generally called the control “bandwidth”.

The voltage runback deadband is used to assurethat the runback setting is sufficiently above theupper voltage limit setting to limit hunting. It isadjustable from 1.0 to 4.0 V in 0.1 V increments,and must be set greater than the voltage change ofone single tapchange, or hunting will occur. It issuggested it be set for approximately twice thevoltage change of one tap.

If the voltage exceeds the runback limit, as mightbe caused by combinations of LDC action and loadshifts or by a system disturbance without LDCaction, the control will immediately call for an“automatic” lower without any time delay. The lowercommand will continue until the voltage is reducedbelow the runback voltage limit. After this occurs,


3–6

the timer will reset. If the voltage is still high, normalcontrol action will bring the voltage down to withinthe normal control band.

Overvoltage block can be effectively disabled bysetting it to 135 V. By setting the runback deadbandto 4 V, the runback voltage becomes 139 V whicheffectively disables the feature.

Undervoltage BlockRefer to the Appendix, Figure A-4. This limit isadjustable from 95.0 V–135.0 V in 0.1 V increments.This limit can be set to limit low customer voltage tosafe limits and will block voltage reduction actionthat could cause motor stalling and other undesirablelow voltage effects. Undervoltage block can beeffectively disabled by setting it to 95 volts. If thevoltage is below the Block Lower setpoint, the controlwill not respond to further lower commands. Raisecommands are not affected. Operation of theovervoltage limit, voltage runback and undervoltageblock is illustrated in Figure 3-2.

Coordination with Backup RelayThe M-2001C (BASE-R) Digital Tapchanger Controlprovides the first customer protection functions.Use of a back-up relay, such as the M-0329B, isrecommended since the M-2001C (BASE-R) (or anyindependent control) cannot be expected to be itsown backup. The back-up relay bandcenter settingis usually set the same as the primary control, withthe bandwidth setting 1 or 2 volts greater than theprimary control bandwidth, the block raise setting 1volt greater than the primary control, and thedeadband setting 1 or 2 volts. These settings createa runback level 1 or 2 volts above the runback levelof the primary control.

If primary control operation is desired first, the blockraise setting and the resulting runback level of thebackup realy must be higher than those of theprimary control and the block lower setpoint must belower than the primary control setting.

Tap Position BlockSince Keep-Track is the sole method of tap positionknowledge on the M-2001C (BASE-R), Tap BlockRaise and Tap Block Lower are fixed at +16 and –16, respectively.

The Tap Position Block is disabled by setting theTap Information screen to the Disable condition.Refer to the Appendix, Figure A-5. If the TapInformation screen is not disabled, the Tap Positionblock can be disabled by setting the Tap Limitsscreen to Disable.

Overcurrent Block Operation▲ CAUTION: The current input to the control israted at 0.2 A continuous, 0.4 A for two hours, and4.0 A for 1 second.

Refer to the Appendix, Figure A-4 for the Line Limit Iscreen of the Setpoint Menu. The Line Limit Currentsetpoint is available to block operation wheneverthe current exceeds the setting. Depending on thecurrent scaling choice made in the Configure menu,the setting is adjustable from 0.2 to 0.64 amps in0.01 amp increments, when using a 200 mA CTscale. If “Curr Transformer” is set for 1 A, thesetting is adjustable from 1.0 to 3.2 Amps, and if the“Curr Transformer” is set for 5 A, the setting isadjustable from 5.0 to 16.0 Amps.

This feature can be used to protect the tapchangerswitch during periods of excessive current. Thisfeature can be effectively disabled by setting theblocking current to 0.64 amps, 3.2 Amps or 16-0amps, depending on scaling CT choice.

3.5 Pulsed Output

When the output selection is “Pulsed”, the pulsewidth can be programmed from 0.2 to 12 seconds,in increments of 0.1 seconds.

When the output is set to "Pulsed" and the control iscalling for Raise/Lower, an output will turn on for thepreprogrammed time, or until a counter contactoperates, and then turn off the output for a timeperiod of 0.5 seconds plus the intertap time delaysetting value. When the control is calling for aRaise/Lower and no counter input is applied, theoutput will activate for the full preprogrammed timeand deactivate for 0.5 seconds, plus the intertaptime delay.

When enabling the pulse feature on an LTC withouta counter contact, to prevent hunting, care must betaken to set the ON pulse width less than the time ittakes for a complete tap change to occur, but longenough for the seal-in circuit to be activated. TheIntertap Time Delay should be longer than the time ittakes for a complete tapchange to occur.

When a counter input is applied, and there is anintertap delay, the pulse will cease immediately(triac is turned off) with counter contact closure forthe intertap time delay. After the counter contactopens, the intertap timer will start at the end of thetime delay. If there is still a Raise/Lower condition,another pulse will start.


3–7

3. Command another tapchange after theintertap time delay has expired, withoutregard to the basic timedelay setting, if the voltage remains outof band in the same direction as theprevious tapchange.

■ NOTE: The intertap time delay applies a shortdelay after every tapchange, for the user-selected time delay (0 to 60 seconds). Itis enabled via a menu screen. Forapplication with pulsed output, seeSection 3.5, Pulsed Output.

Test Mode/Status ScreenThis convenient screen permits entering a biasvoltage for simulating the raising or lowering of thesensed input voltage. This exercises the control asif the input voltage were being changed. The contactsactually operate.

This screen is valuable in the rapid determination ofoperating quantities present to influence the normaloperation of the control. Items that will blockoperations or change setpoints are described hereand illustrated by LEDs on the face of the control.

The Test Mode/Status screen displays control statusinformation that includes:

• Output Status

• Compensated Voltage

• Band Status

• Runback/Blocking Status

• Voltage Reduction Status

This screen automatically resets on exit or in 15minutes if not exited. Refer to Appendix A, FiguresA-2 and A-3.

3.6 Application Considerations

SequentialThe control operates in Sequential Mode. In thismode, the tap change output is initiated after thetime delay timer has timed out. The tap changeoutput will remain “on” until the control senses thatthe voltage has returned in-band. This permitssuccessive tap changes to be made in a “sequential”mode with no delay between tap changes.

If a delay between successive tap changes isdesired, an intertap time delay may be used. Thisvalue is set at the Intertap Delay screen in theConfiguration Menu. The value is set from 0 to 60seconds and will interrupt tap change outputs forthe preset time after a counter-contact closure isdetected by the control's operations counter input #1.

Intertap Time DelayThe intertap time delay may be used in conjunctionwith sequential operation or pulsed output. Thenormal operation of this delay timer is as follows:once a tapchange command is initiated, when therewould normally be a continuous command (raise orlower) to run the tapchanger until the voltage hasreturned to within the band setting, there is now anintertap time delay initiated between tapchanges.When the intertap time delay is set to zero, it isdisabled.

When invoked by a user who possesses Level 2security access (or above), the intertap time delaywill:

1. Recognize that a tapchange hasoccurred, indicated by the countercontact input.

2. Remove the output signal and wait forthe intertap time delay, even though thevoltage remains outside the designatedvoltage band.

4.0 Introduction

This section describes the Configuration Menu ofthe software flow. Refer to Appendix A, Figures A-5and A-8.

■ NOTE: Panel display for configured items do notrefresh. In order to reflect the change,user must scroll past the screens andthen return.

4.1 Passwords

Initializing Passwords (Control)Refer to the Appendix, Figure A-5. The Level 1 andthe communications passwords are set to all 0000at the factory. The Level 2 password is set to 2222at the factory and that password must initially beused to access the Configuration Menu. See Chapter9, M-2029A TapTalk®, Utilities/Set New Passwordssection.

New passwords may be entered from the screenwithin the Configuration Menu as described below.As soon as new passwords are entered, they will berequired. Changing any setpoint or configuration willrequire the password, if enabled. Enter passwordswith care and record them for future use!


4–2

Disabling PasswordsAny one of the three passwords can be disabledwithin the screens of the Configuration Menu bychanging the password to zero (0000). When apassword is disabled, its access screens will not beseen and the password will not be required.

Configuration ChangesUse the rrrrr and ooooo pushbuttons to display the ToConfiguration Menu prompt and press ENT. TheLevel 2 password is required for entry, unlessdisabled. Use the rrrrr, ooooo and ENT pushbuttons tochange the configuration.

4.2 User Identification

Changing User LinesRefer to the Appendix, Figure A-8. The user stationidentification lines allow the user to uniquely identifythe unit. In normal operation, after 15 minutes withoutpressing a pushbutton on the display, the screenwill be blank. If the screen is blank, any pushbuttonpress will reactivate it and display the User Linesscreen. Each line of this display can have up tofifteen ASCII characters. Both of the lines are factorypreset with asterisks.

When ENT is pressed at the User Line screen in theConfiguration menu, an underline cursor is displayedunder the left-most digit. Each digit is changed byusing the rrrrr and ooooo pushbuttons to select the ASCIIcharacter (the ASCII character list begins with “!”).The ENT pushbutton is used to move the underlineto the next digit. When the ENT pushbutton ispressed for the right-hand digit, the new user line isstored into nonvolatile memory.

4.3 Counters

▲ CAUTION: When "Input Selection 1" configurationis set to "Seal-In," the Counter Input is used as theSwitch Status Input and the Seal-In Input will causethe counter to increment.

The M-2001C (BASE-R) includes three configurationsetpoints for the proper operation of the counterfunctions. These are necessary due to the differenttypes of counter contacts on various equipmentusing these Digital Tapchanger (DTC) controls andthe effect of wear on older counter operatingmechanisms.

▲ CAUTION: Please record all passwords in asecure location. If the password is lost or forgotten,please contact the factory.

Configuring PasswordsThe user who possesses the current Level 2password may change any password using four newnumbers. A password is not required if the Level 2password has been set to 0000.

When ENT is pressed while viewing the password atits screen within the Configuration menu, anunderline cursor is displayed under the digit furthestto the right of the password.

Each digit is changed by using the rrrrr and ooooopushbuttons to select the number. Use the ENTpushbutton to move the underline to the left. Whenthe underline is on the far left digit, press ENT andthe new password is stored into nonvolatile memory.If a wrong number has been entered, press ENT asmany times as necessary and the underline willmove to the digit furthest to the right for entry of thecorrect password. This should be done immediatelyto ensure that an incorrect password is not stored inmemory.

If no key entry is made for approximately 15 minutesand the screen goes blank and the digit furthest tothe left has not been entered, the password willrevert to the previous one regardless of digits thathave been changed. After a new Level 2 passwordhas been entered, the new password must be usedto reenter the Configuration menu. Be sure torecord the new password for future use.

When a communication password has beenconfigured at the control, the communicationpassword allows the user to bypass both theconfiguration and setpoint passwords otherwiserequired by a control.

■ NOTE: The communication password is identifiedas a string #. Therefore, the passwords"0001" and "1" are not interchangeable.

Each control can be given a unique, 4-digit passwordranging from 0 to 9999. If the password has beenconfigured at the control as 0000, communication isnot restricted a password does not need to beidentified by M-2029A. The control is shipped withcommunication password disabled (set to 0000).

Configuration – 4

4–3

Operations CounterThe user must select the method of countingtapchanger operations consistent with thetapchanger.

X1 – Operation count will increment by one with anopen-close-open state change on the tapchangercounter switch. The closed state may be present foras little as 20 ms. The open state may be presentindefinitely.

X2 – Operation count will increment by one witheither an open-close or a close-open state changeof the tapchanger operation counter switch. Boththe closed and open states may exist indefinitely.

Count Window – Operation count will incrementby only one count during a set time period or "CountWindow". This is true no matter how many counterinputs occur during the count window time. After acounter input is accepted, the count window timerbegins and another count won't be accepted untilthe count window time expires. The count windowtime can be set from 0.5 to 10.0 seconds, under theConfiguration menu.

The counter accommodates 999,999 operationcounts and the number of counts stored in memoryis not affected by a loss of supply power. Totaloperation count is displayed in the Status Menu.This counter cannot be reset, but can be preset toany value up to 999,999 in the Configuration menu.

Resettable Operations Counter

A second, resettable, operations counter operateswith the method selected by X1/X2/Count Window.The user resets this counter to zero by pressingENT while viewing the resettable operation counterscreen within the Status Menu. No password isrequired to reset the resettable operations counter.

■■■■■ NOTE: The counter will only increment with aconnection to the counter input.

4.4 Correction Factors

VT Ratio CorrectionRefer to the Appendix, Figure A-5. The operation ofsome regulators is such that the internal VT doesnot provide the desired voltage ratio. In these cases,it is desirable to correct the VT secondary voltage toa 120 V ac reference base. This change is easilymade in software, eliminating the need for a multi-tap sensing transformer.

▲ CAUTION: The use of a voltage correction factoris incorporated in the calculation of primary quantitiesin the control, and erroneous values will be displayedand recorded if the VT correction factor is notincluded in the PT multiplier.

The correction is derived from information providedby the regulator original equipment manufacturer(OEM). The numerical value of the correction is thevalue, in volts, required to adjust the VT nominalsecondary voltage to 120.0 volts. The correctionrange is ±15 volts in 0.1 volt increments.

■ NOTE: The maximum allowable continuous VTsecondary voltage is 140 volts. Thecorrection is made only in software. As aresult, the value of V

LOCAL read on the

control display will differ from thatmeasured at the voltmeter test terminalsby the percent of the correction voltage.

CT/VT Phase ShiftRefer to the Appendix, Figure A-5. The control willrecognize forward and reverse power flow to theload. With the CT and VT (reference) signals in-phase for unity power flow to the load, it will properlycalculate line drop compensation. Depending on theconnection of the CT and VT, the phasors may notbe in-phase. If this is the case, the phase shift canbe corrected in software. The usual characteristicsof three phase systems only allow multiples of 30°phase shifts. The control, therefore, has a range of0° to 330° in 30° increments.

By comparing system operating conditions withpower flow direction and power factor as shown onthe M-2001C (BASE-R) Tapchanger Control, improperphase shift can be determined. An incorrectconnection may be resolved using well-known phasormethods. The following procedure may be useful tocheck the choice of correction or even to determinethe correction by trial and error:

1. Put the transformer or regulator onmanual control.

2. Determine the Watts and VArs load onthe transformer or regulator from othermetering.

3. Read the Watts and VArs indicated bythe control, and make certain that theyare of the same sign and ratio ofmagnitudes as obtained from the externalreadings.

4. If not, change the correction in 30°increments until the control and externalreadings are in best agreement.


4–4

When two single-phase regulators are connected inopen delta, the current signals will be out-of-phasewith the voltage signals. For one regulator, thecurrent will lead the voltage by 30° and is called the“leading” regulator. For the “lagging” regulator, thecurrent will lag the voltage by 30°.

Contact Beckwith Electric for Application Note #17for more information on VT and CT connections.

4.5 Ratio Multipliers

Voltage & Current Multipliers▲ CAUTION: The use of a voltage correction factoris incorporated in the calculation of primary quantitiesin the control. Although the control operation is notaffected, erroneous values will be displayed andrecorded if the VT correction factor is not includedin the PT multiplier.

Refer to the Appendix, Figure A-5. Primary quantitiesare displayed when voltage and current multipliersare set into the control. The voltage multiplier is:Vmult = Vpri/(Vsec + Vcorr)

For a VT ratio of 7620/117 V and a voltage correctionof 3 V, the multiplier is:V

mult = 7620/(117 + 3) = 63.5

The voltage multiplier setting range is from 0.1 to3260 in 0.1 steps.

The current multiplier is the value of the line CTprimary rating divided by 0.2 A. For a CT primaryrating of 1000 A, the multiplier is:CT

mult = 1000/0.2 = 5000

The current multiplier setting range is from 1 to32600 in 1.0 steps.

Both multipliers are entered in the Configurationmenu.

▲ CAUTION: The current input to the control israted at 0.2 A continuous, 0.4 A for two hours, and4.0 A for 1 second.

■■■■■ NOTE: The current transformer selection in theConfigure menu only changes the scalingfactor for current reading and setting.

4.6 Tap Information

The M-2001C (BASE-R) Digital Tapchanger Controltap position information applies to 16 taps. Theuser is able to select the Keep Track or to disablethis feature. Table 4-1 outlines the two selectionsavailable for the Tap Information screen.

Tap Position by Keep Track (Reg Internal)▲ CAUTION: This feature is applicable to single-phase regulators only.

▲ CAUTION: This feature is only applicable for16 tap ranges with neutral tap and neutral indicator.

The source voltage will only be applicable with a taprange of 16 taps.

This feature allows the control to keep track of thepresent tap position. The “Reg Internal” setting isselected for this method.

88888 WARNING: Do not rely on the tap positionindication on the M-2001C (BASE-R) TapchangerControl display for neutral position whenbypassing voltage regulators.

The motor power source for the manual or automaticinitiated tap changes must be the same as themotor power input to the control. The operationscounter and neutral light circuit should be operational.The counter input and power source is required fordetecting tap changes and determining direction ofthe tap change. Connecting a regulator neutral tapposition indicating contact to the control will resetthe tap position to neutral each time the tap goesthrough the neutral position. It is recommended thatthe indicated tap position be compared to themechanical tap position indicator at regular intervals,and that the indicated value be corrected, ifnecessary.

The tap position stored in memory is not affected bya loss of power. The tap position record is checkedand corrected to neutral, if necessary, with theclosure of a neutral contact (when the neutral tapposition contact is connected to the controls).

▲ CAUTION: When the keep-track tap positionmethod is used, it must be calibrated for propervoltage control with reverse power operation.

If desired, the keep-track feature can be disabled inwhich case the screen will indicate “Disabled.”

Configuration – 4

4–5

The user initializes the control at a given, known,tap position upon installation, by selecting RegInternal in the Tap Information screen in theConfiguration Menu and performing the followingsteps:

1. Determine the actual tap position fromthe external tap position indicator on theregulator.

2. Scroll through the display to the TapCalibrate screen in the Configurationmenu. Press ENT. A flashing “C”indicates that the control is ready toaccept data. Press the rrrrr or ooooo pushbuttonuntil the correct tap position is displayed.Press ENT again. The tap position isnow calibrated to recognize allsubsequent operations so as to “keep-track” of the present tap position.

3. The present tap position is indicated inthe Status Menu at the Tap Positionscreen.

Or, if the neutral tap position contact is connectedto the control, run the regulator to neutral as shownby the tap position indicator on the regulator. Thecontrol will recognize the neutral light signal and setthe tap position accordingly.

The keep-track procedure recognizes tapchangescommanded via manual or automatic contacts.The power source for the manual-initiated tapchangesmust be the same as the motor power source usedfor the automatic tapchangers.

The keep-track position knowledge is based on thedetection of a closed switch (manual or automatic),and feedback from the operation counter input.

The method by which Keep Track is achieved is asfollows:The control includes two Zero Voltage Detection(ZVD) circuits. These circuits individually monitorthe AC voltage across the internal raise and lowertriacs. This is done since any external raise or lowercontacts or manual switches have to be placed inparallel with the triacs to run the tapchanger motor.When the triacs (or any contact paralleled acrossthe triacs) closes, the voltage measure decreasesto almost zero. When a counter input event isreceived while the raise circuit is activated, theKeep Track will increment the tap count by one.When a counter input event is received while thelower circuit is activated, the Keep Track willdecrement the tap count by one.

If the tapchanger reaches the mechanical tap limitsof operation, ( 16), limit switches open up theappropriate circuit so the control cannot force araise above +16, or force a lower below –16. This ispotentially confusing to the ZVD circuits, since theycan see zero voltage on the output with a closedtriac and also see zero voltage on the other outputdue to an open limit switch. When this condition isencountered, the control can only make a bestguess of which operation really occurs and movesone step in the direction of neutral, which should beaway from the side with the open limit switch.

An additional feature is the neutral zero feature.When a regulator passes through the neutral position,a neutral contact closes. This is most often used todrive a neutral light that is an indicator that themechanism is in the neutral position, and it is safeto bridge the input and output of the regulator becausethey are at the same voltage. Upon detection of aneutral circuit closure, Keep track resets the tapposition to neutral to resynchronize the circuit.

4.7 Reverse Power Operation

Detecting Reverse PowerReverse power flow exists whenever the realcomponent of the line current changes directionfrom forward and remains until another reversal tofoward power occurs. The control reliably determinespower direction with as little as 2% of the realcomponent of the nominal 200 mA line current (4.0mA).

Power Direction Bias ConfigurationThe Power Direction Bias Configuration screencontains three settings to determine how the controlwill switch between forward and reverse poweroperation. The three settings are No Bias, ForwardBias, and Reverse Bias.

"No Bias" SettingWhen the Power Direction Bias function is set to"No Bias", the control applies an 8 mA hysteresisband with a bandcenter of 0 load current (+4 mAto –4 mA) to switch between forward and reversepower. The control will switch from forward power toreverse power when the load current exceeds –4mA (reverse direction). The control will switch fromreverse power to forward power when the load currentexceeds +4 mA (forward direction).

"Forward Bias" SettingWhen the Power Direction Bias function is set to"Forward Bias", the control applies a 0 mA to -4 mAhysteresis band to switch between forward andreverse power. The control will switch from reversepower to forward power when load current is PPPPP 0mA (forward direction). The control will switch fromforward power to reverse power when the load currentexceeds –4 mA (reverse direction).

"Reverse Bias" SettingWhen the Power Direction Bias function is set to"Reverse Bias", the control applies a 0 mA to +4mA hysteresis band to switch between forward andreverse power. The control will switch from forwardpower to reverse power when load current is OOOOO 0mA (reverse direction). The control will switch fromreverse power to forward power when the load currentexceeds +4 mA (forward direction).

Upon detection of power reversal, after a 5 seconddelay, the control will operate in the selected mode.The operating mode is selected from the followingoptions:Ignore – The control will take no different actionthan in the forward direction. It essentially does notuse the power direction in the control decisions.

This is the same as a control which does not havepower direction knowledge.

This mode is intended for use on distribution systemswhich have the possibility of power reversal becauseof distributed generation (DG) on the feeders. Inthese applications, the DG usually does not havethe capacity to control the voltage with the morepowerful system intact.

The condition required for DG to control the voltageis the generation and transmission of large amountsof VArs through the line impedance back towardsthe system source. Usually two items prohibit thisaction: 1) the ability of the DG to generate thoseamounts of VArs and 2) the contractual obligationsenforced by many utilities that the DG only affectKWs on the system.

Block – Inhibits automatic tapchange operation.This locks the tapchanger on the tap position in useat the time reverse power flow is detected. It is therecommended setting for independent powerproducers or in situations when reverse power flowis not expected. The control will revert to normaloperation when forward power flow resumes.

Regulate REV (single-phase regulators only) – Thecontrol will detect reverse power flow and regulateaccording to reverse power settings as selected inthe Setpoint Menu. With tap position knowledge, thecontrol calculates the source-side potential withoutthe use of a source side VT. This feature is designedfor use with feeder voltage regulators which continueto operate in a radial mode after system switchingcauses the power flow reversal.

The source voltage is calculated by knowing thelocal voltage, the load current, and the tap positionusing a presumed regulator impedance. Thatimpedance is a function of the tap position. Thecalculated source voltage is only valid with a5/8% step-voltage regulator.

With the control recognizing reverse power flow, thefollowing occurs:

• The REV PWR LED is illuminated.

• Reverse power setpoints are used.

• Source voltage is calculated and motoroutput commands are reversed. Forexample, when the voltage is high, thecontrol raises the tap thereby lowering thevoltage and a lower is indicated on thefront panel LEDs.

Configuration – 4

4–7

Return to Neutral – To use this feature, a counterinput must be provided, and one of the tap informationmodes must be enabled.

The Return to Neutral feature will cause the tapposition to be driven to neutral when reverse poweris detected. Tap position will be driven to neutralregardless of the voltage or currents present at thecontrol. Once neutral is reached, the tap positionwill remain unchanged as long as reverse power ispresent. Normal operation will resume when forwardpower is detected.

This mode is intended as a safe response to apower reversal on a system which can haveconflicting situations. As described earlier, a radiallyoperating system with reverse power should be setto "Regulate Rev." However, if a DG causes apower reversal, the proper setting is usually "Ignore."In an application where both conditions are possible,and it is not possible for the control to determine thecause of power reversal, the proper setting of "Returnto Neutral" is advised.

4.8 Output Selection

Output SelectionThere are two setup screens associated with thisfeature. This screen is located in the Configurationmenu. A selection of continuous or pulse may bechosen.

Output PulseLocated in the Setpoint menu. The output pulse canbe programmed from 0.2 to 12 seconds, inincrements of 0.1 seconds. An initiated pulse willcontinue until the pulse time has been reached or acounter contact operates.

■ NOTE: When enabling the pulse feature on anLTC without a counter contact, care mustbe taken to make the ON pulse widthless than the time it takes for a completetap change to occur, but long enough forthe seal-in circuit to be activated. TheIntertap Time Delay should be longerthan the time it takes for a completetapchange to occur.

ContinuousThe output is continuous until the voltage returnsinto the bandwidth.

4.9 Protocols/Communication

The front communications port, COM2, uses BECO2200 exclusively.

4.10 Basic Timer Types

The time delay of the control may be selected fromtwo different types. Selection of an Integrating timertype increments the timer when the voltage is outsidethe band, and decrements the timer towards zerowhen the voltage is within the band. Selection ofInstantaneous timer type increments the timer whenthe voltage is outside the band, and resets to zeroinstantly when the voltage returns within the band.

4.11 Data Logging

This feature allows you to configure the parametersthat the control will use to log data (with M-2029Asoftware) to an Excel or Lotus123 compatiblespreadsheet file. Once the log parameters areuploaded through M-2029A, the control will log datato on-board memory. Logging will continueindefinitely until a new set of log parameters areuploaded, at which point all previously logged datawill be lost. It is necessary that the log parametersare set up, and logging be initiated, through the DataLogger for this feature to work as expected.

There are 19 communication points associated withthe data logging on the control. Data logging may beset/read from the BECO 2200 protocol.

There are four command points:

Log Sample Period – This is a read/write point.Data range is 1–9,999 minutes in increments of oneminute.

Full Record Flag – This is a read only point. Itreads zero if the memory has not yet been writtenover. Reads one if the data has wrapped around,and overwritten previous data.

Log Point Select – This is a read/write point.Data is set in binary format.

Log Status – This point is a command/status/read/write point. Command/status is as follows:

0 Not logging (command)When a zero is written to this point, loggingwill stop.

1 Logging (status)If log status reads 1, logging is in progress.


4–8

3 Start Logging (command)When a three is written to log status,logging will start. Points 9-00 and 9-02must be set up prior to issuance of alogging command. Logging will continueindefinitely, or until a stop logging command(0) is issued, in a circular buffer manner.The absolute size of the data logging arrayis 311,040 bytes. The start address ofthis buffer is 90000 hex. Data will alwaysbe logged in records. If the last recordexceeds this number (311,040), then thefirst record at address 90000 hex will beoverwritten.

4 Download (command)When a four is written to log status:

• The oldest record time stamp can be readin BECO 2200 9-04, 9-05, 0-06.

• The newest record time stamp can beread in BECO 2200 9-07, 9-08, 9-09.

• The current logged data pointer can beread from BECO 2200 9-10, 9-11.

• The ready to download logged data pointercan be written in 9-12, 9-13.

• The first parameter of a record (a 16 bitword of information pointed by 9-12 and9-13), along with the next 14 words willbe ready for query with BECO 2200protocol. You must issue a read of 15points (only), starting with point number9-14. Be aware that this scheme will notread records. It will read 15 words at atime, crossing record boundaries. It willstart by reading the 1st parameter in arecord, then it will read the next 15 words.As this happens, the control will set upthe next 15 words to be read, startingwith point 9-14, by incrementing theready-to-download logged data pointeraccordingly.

4.12 Current Display/Scaling

The current input rating of the M-2001C (BASE-R)Tapchanger Control is 200 mA, continuous. AuxiliaryCT's are necessary if primary currents exceed thisvalue.

The Current Transformer scaling selection is set inthe Configure menu to be 200 mA, 1 A or 5 A. Thischoice fixes the scale of both the metering readoutquantities and the settings of current values.

The status screen showing this information,CONTROL LOAD I, will be updated accordingly

8 WARNING: This selection is for scalingpurposes only, and neither 1 A nor 5 A shouldbe input to the control.

The values of the current displayed in the controlload I, and on circulating current screens can bedisplayed in either 200 mA, 1 A or 5 A scale.


The Line Limit Current setpoint screen is also affectedby this selection.

Configuration – 4

4.13 Regulator Type

Regulator Type A or B can be selected in theConfiguration menu. This will allow the sourcevoltage to be calculated correctly for either type ofregulator (see Figure 4-1). It will also allow thecontrol to operate more accurately when in the"regulate in reverse power" mode.

General Electric VR-1 voltage regulators are availablein two winding configurations; Type “A” non-invertedconfiguration and type “B” inverted configuration.These types refer to the internal power componentconnections. See figure 4-1.

The Type “A” non-inverted configuration regulatorhas a wire jumper on the NN terminal block forPotential Transformer tap selection.

On the older regulator controls (those not havingpower disconnect and CT shorting knife switches),the PT tap selection jumper is usually connectedbetween terminals NN-9 and NN-20, NN-21 or NN-22.On newer regulator controls, (those with powerdisconnect and CT shorting knife switchs), the PTtap selection jumper is usually connected betweenterminals NN-8 and NN-20, NN-21 or NN-22. Thereare special cases when a PT ratio correctingtransformer is supplied and the jumper position isdifferent. In all cases please consult the regulatortank nameplate for the proper jumperconnections.

The Type “B” inverted configuration regulator issupplied from the factory with a standard 0.75 ohmresistor installed on the NN terminal block in additionto the PT tap selection jumper. This series resistorlimits short circuit currents in the event of an externalfault.

On the older regulator controls (those not having apower disconnect and CT shorting knife switches),the resistor is usually connected between terminalsNN-9 and NN-22. The PT tap selection jumper isusually connected between terminals NN-22 andNN-20 or NN-21. On newer regulator controls, (thosewith power disconnect and CT shorting knife switchs)the resistor is usually connected between terminalsNN-8 and NN-22. The PT tap selection jumper isusually connected between terminals NN-22 andNN-20 or NN-21. In all cases please consult theregulator tank nameplate for the proper jumperconnections.

The control can be damaged if the PT tap selectionjumper is not connected properly when the regulatoris energized.

The control is not powered if either the PT tapselection jumper or resistor is missing or open.

The customer should always verify properconnections by consulting the nameplate on theregulator tank. The customer is cautioned that thenameplate on the control cabinet could possibly beincorrect if the control has ever been replaced. If theserial number on the control cabinet matches theserial number on the regulator tank or nameplate,the control cabinet nameplate may be consulted forproper jumper configuration.

Demand MeteringRefer to the Appendix, Figure A-5. The demandmetering capability provided in the control followsthe concept of a lagged demand meter. The demandtime interval is selected by the user as 15, 30 or 60minutes. This is the time it takes for a thermalmeter to indicate 90% of a change in load.

Quantitative MeteringRefer to Appendix A, Figure A-2. The quantitativemetering function of the control displays the followingmeasured values on the individual status screens:

• Total Reverse VAr Hours (KVArHR,MVArHR or GVArHR)

• Total Forward VAr Hours (KVArHR,MVArHR or GVArHR)

• Total Reverse Watt Hours (KWHR,MWHR or GWHR)

• Total Forward Watt Hours (KWHR, MWHRor GWHR)

The measured values are retained in non-volatilememory. A real time clock is utilized to record adate/time stamp for each quantity to indicate whenthe period of measurement was initiated.

When a quantitative metering screen is selected,three screens cycle continuously to indicate thetotal value, date and time the measurement wasinitiated. The E indicates that the measured valuecan be reset by pushing ENT.

5.2 Drag-Hand Display Quantities

Refer to the Appendix, Figure A-5. Drag-handquantities are the maximum and minimum values forthe period since the last reset command. These areretained in non-volatile memory. A real-time clockallows the recording of a date/time stamp with eachdrag-hand quantity. The following are available fordrag-hand use:

• Min/Max tap position (when Tap Positionis enabled)

• Min local voltage (120 V base)

• Max local voltage (120 V base)

• Max load current

• Max watts, kW or MW

• Max VAr, kVAr or MVAr

• Max VA, kVA or MVA

• Power Factor at max VA

Where primary quantities are used, values displayedare single-phase or three-phase as defined in the PriPwr Display Screen of the Configuration Menu.

▲ CAUTION: When the M-2001C (BASE-R)Tapchanger Control is used with a Beckwith Electricadapter panel, the panel’s drag hands reset buttononly resets the mechanical drag hands of theregulator or LTC transformer. The button does notreset the tap draghands information stored in thecontrol. The maximum and minimum tap position ofthe control should always be reset when themechanical drag hands are reset.

The values retained in memory are time-taggedquantities that are calculated using the demandperiod selected (15, 30 or 60 minutes). For voltage,values are the average of samples taken over aperiod of 32 seconds which avoids undue retentionof momentary voltage transients. The load powerfactor retained is the value at the time of max VA.

When selected, three screens for each parametercycle continuously and indicate the value, dateand time of each parameter. The E indicates thatthe drag-hand can be reset by pushing ENT.

5.3 Real-Time Clock

Refer to the Appendix, Figure A-2. The control isequipped with a real-time, 24-hour clock which isused with the drag-hand feature to record date/time stamp information on quantities saved inmemory. The power source for the clock ismaintained for at least 24 hours during a systempower outage by a charged capacitor (no battery).If the power outage lasts longer than 24 hours,check the clock and reset if necessary.

5.4 Line Frequency

Refer to the Appendix, Figure A-2. The controlprovides for real-time metering of the line frequency.If the control is a 60 Hz model, the operatingfrequency is 55 to 65 Hz; if the control is a 50 Hzmodel, the operating frequency is 45 to 55 Hz.

5.5. Voltage Reduction Status

▲ Caution: Enabling this function may shorten thelife of the screen.

Refer to Figure A-5. The control has a flashingvoltage reduction status which can be enabled/disabled in the Flash V Red Mode screen of theConfiguration menu. When enabled, and voltagereduction mode is active, the display will show thelocal voltage for approximately two seconds, thenturn off for approximately 7 seconds. Then thevoltage reduction status will be displayed forapproximately two seconds, then turn off for about 7seconds. Then the cycle will repeat, as long asvoltage reduction mode is active and the front panelpushbuttons have not been used in the past fiveminutes.

5.6 Removal of Select StatusScreens

Select status screens can be removed by pressingand holding the ENT pushbutton, and then alsopressing the ooooo pushbutton. This will cause thepresent status screen to be removed from the statusmenu for quicker status access. Only the screensthat do not use the ENT button in any way can beremoved. The status screens that can be removedare: Comp. V, Source V, Circ I, Load I, PowerFactor, Primary screens (V, I, VA, Watts, VArs),Total Op Count, Pf at Max VA, and Timers. All ofthe screens can be restored from the "RestoreStatus Screens" menu item in the Configurationmenu.

M-2001C (BASE-R) Control (Blue Connector)▲▲▲▲▲ CAUTION: These binary inputs must be "wetted"by connection to Pin 10 ONLY – a nominal 12 V dcsource. If the contacts are connected to a 120 V acsource, it will result in damage to the control. Externalconnections to the control are shown in Figure 6-1.

■ NOTE: The communication port provides remoteaccess to the tapchanger control usingthe M-2029A TapTalk® CommunicationsSoftware.

Pin 1 Voltage InputThis input accepts nominal 120 V ac, 60 Hz (or 50Hz as ordered) to operate the control's power supplyand voltage sensing input. The acceptable voltagerange for proper control operation is from90–140 V ac.

Power consumption is less than 8 VA. The inputvoltage is referenced to line neutral (Pin 3).

Control users may encounter situations whereactuating the Drag Hands Reset pushbutton on oneof any of our adapter panels results in the loss ofVoltage Sense fuse. The Drag Hands reset solenoidis powered from the circuit tha powers the cotnrol,and provides the control with sensing voltage.Initially, a 1/4 ampere fuse was used in this circuit,and most recently a 1 ampere fuse was substitutedto prevent further loss of the fuse. This phenomenonis due to the fact that as solenoids age, then maybecome sticky due to mechanical misalignment,hardened grease, or shortened windings.

The adapter panels include a 1 ampere fuse in thevoltage sense circuit. This value should be adequatefor all but the most extreme problems. When a DragHands Reset Solenoid that consistently blows a 1ampere fuse is encountered, it is recommended thatthe customer either remove the solenoid for cleaningand adjustment, or replace it completely.

Pin 2 Load Current ReturnThis is the non-polarity input to the load currentmeasuring transformer. The companion polarity inputis Pin 4. The line current transformer input is isolatedfrom other pins.

Pin 3 NeutralThis is the return for the Voltage Input (Pin 1), andnominal +12 V dc “wetting” voltage (Pin 10).

Pin 4 Load Current PolarityThe line current input range is 0–640 mA (200 mAcontinuous) with 200 mA representing the 1.0 per-

unit value. The measured current value is used forline drop compensation and metering calculation.

▲▲▲▲▲ CAUTION: The current input to the M-2001C(BASE-R) is rated at 0.2 A continuous, 0.4 A for twohours, and 4.0 A for 1 second.

Pin 5 Not Used

Pin 6 Not Used

Pin 7 Tapchanger RaiseThis switched output connects the tapchanger raisewinding to the source of motor power. When thecontrol calls for a raise, it is capable of switching upto 6 A at 120/240 V ac.

Pin 8 Motor Power InputThe source for powering the tapchanger motor isconnected here. It may have a maximum voltage of240 V ac.

Pin 9 Voltage Reduction Step #2This digital input is typically enabled by connectingit to the nominal +12 Vdc wetting source (Pin 10),through an external Form "a" dry contact. The amountof voltage reduction implemented is determined bythe setting.

Pin 10 +12 V dc Wetting VoltageThis is the output of an unregulated dc power supplyinternal to the control. It is referenced to neutral andcan supply up to 100 mA. It is used for powering thedigital inputs of the control through external relays.Depending on the voltage suppied to Pin 1 andloading, its output can vary from +10 to +18 V dc. Itis not fused in the control.

Pins 11 & 12 Operations Counter Inputs 1 and 2▲ CAUTION: When "Input Selection 1" configurationis set to "Seal-In," the Counter Input is used as theSwitch Status Input and the Seal-In Input will causethe counter to increment.

This digital input registers the counter contactclosure. The pins are isolated from neutral to permitplacing the external contact in series with either thewetting voltage or neutral. The operation count willincrement when Pin 12 is grounded via thetransformer or regulator dry operation count switch.

This contact is needed for using the intertap timedelay. Once the contact is opened, the intertap timedelay will begin counting down.

Connections– 6

Pin 13 Input 1 - Motor Seal-In/Switch StatusInputWhen the Input Selection (1) screen in theConfiguration menu is set to Seal-In Input, thisinput will operate as a seal-in input and counterinput. In this configuration, the digital input isreferenced to line neutral, but is unique in that it isconfigured to accept only the output of the motorseal-in current detection transformer, from the B-0553motor seal-in printed circuit board subassembly.The B-0553 is a supplemental circuit board used inthe appropriate adapter panels.

When the Input Selection (1) screen in theConfiguration menu is set to Switch Status Input,this input will only operate as a switch status input.All seal-in input functions will be disabled. In thismode, the switch status on the adapter panel can beread to determine if it is in Auto or Manual ON/OFF.The status can be read through the seal-in/switchstatus data point in the communications protocols.

Pins 14 & 15 Neutral Position Detector InputThis digital input registers neutral position switchclosures on regulators. The pins are isolated fromneutral to permit placement of the external contactin series with either the wetting voltage or neutral.Normally the wetting supply (Pin 10) will beconnected to Pin 14.

Pin 16 Tapchanger Lower OutputThis switched output connects the tapchanger lowerwinding to the source of motor power. When thecontrol calls for a lower, it is capable of switching upto 6 A at 120/240 V ac.

Pin 17 Not Used

Pin 18 Voltage Reduction Step #1This digital input is typically enabled by connectingit to the nominal +12 V dc wetting source (Pin 10)through an external Form “a” dry contact. The amountof voltage reduction implemented is determined bythe setting.

■ NOTE: Enabling both voltage reduction step #1and step #2 inputs simultaneously willresult in the level of voltage reduction asspecified on the voltage reduction step#3 screen of the control.

Pin 19 Motor Seal-In Disconnect OutputThis output connects to the B-0553 motor seal-inprinted circuit board subassembly. When the seal-indetector input is actuated, this output drives a triacon the B-0553 motor seal-in printed circuit boardsubassembly to temporarily disconnect the motorpower to the control. The B-0553 is a supplementalcircuit board used in the appropriate adapter panels.

Pins 20 & 22 Not Used

Pins 21 & 24 Not Used

Pin 23 Non-Interruptible Power Supply InputThis input is normally connected to Pin 8, the motorpower input. The power to Pin 8 is interrupted by themotor seal-in process of the B-0553 motor seal-inprinted circuit board. The purpose of Pin 23 is toprovide continuous power to the raise and lowerkeep-track detection circuits. It should be connectedahead of any motor power interruption (for example,auto/manual, local/remote) of the seal-in circuitry tomaintain keep-track raise and lower operation.

6.2 Multi-Step VoltageReduction

On the M-2001C (BASE-R) Tapchanger Control, Pin9 and Pin 18 on connector P2 are used together toprovide up to three levels of voltage reduction. Theexternal connections to achieve these steps areshown in Table 6-1. Voltage reduction amounts areset within the M-2001C (BASE-R) TapchangerControl software. If these voltage reduction stepsare instituted by communications, the contacts arenot being used simultaneously.

▲▲▲▲▲ CAUTION: Voltage applied through dry contactsto actuate voltage reduction inputs; counter contactsand neutral contacts must be nominal +12 V dcobtained from Pin 10 of the M-2001C (BASE-R)Tapchanger Control. The use of 120 V ac will resultin damage to the control.

6.3 Backup Control

Although usually employed in LTC applications, theM-0329B LTC Backup Control can be useful inpreventing excessive voltage excursions onregulators in applications where voltage control iscritical.

The M-0329B is a single-phase, solid-state backupcontrol that prevents a defective tapchanger controlfrom running the voltage outside the upper and lowervoltage limits. The Block Raise and Block Lowervoltage levels are set by accurately calibrated dials.Refer to the M-0329B Instruction Book for details.

The M-0329B LTC Backup Control or M-5329Multiphase Backup Relay are connected as two-terminal devices to the voltage transformer.

6.4 Communication Port

COM2 is an internal port, and supports only BECO2200 protocol and software updates. COM2 supportsbaud rates from 1200 to 19200.

6.5 Grounding

Ground the control by connecting a suitably sizedwire from the ground stud on the bottom of thecontrol case, to a solid connection to ground. Do notrely on mounting screws for grounding.

6.6 Typical RegulatorConnection

Figures 6-3 and 6-4 show examples of connectionsfor a control with a transformer/regulator controladapter panel. Motor Power and sensing voltagecan be obtained form a common source or from anindependent source having a nominal 120 V acoutput. Normally, this is line-to-neutral voltage,although line-to-line voltage can be used if recognitionis made of any phase shift between the voltage andcurrent signals when using line drop compensation.

▲▲▲▲▲ CAUTION: The current input to the M-2001C israted at 0.2 A continuous, 0.4 A for two hours, and4.0 A for one second.

Load current must be reduced by an appropriateauxiliary transformer to 0.2 A "full scale" beforeconnecting to the adapter panel current inputs.Scaling factors may be chosen to resemble 200mA, 100 mA, or 5 A current transformers in readoutsand current magnitude settings. It is important thatyou obtain an application guide on an adapter panelspecific to your regulator application and followthose instructions.

5. TapTalk is now configured tocommunicate with M-2001 Series controlsusing a modem.

9.5 Communications withMultiple Controls

▲▲▲▲▲ CAUTION: Each control connected to either adirect or modem connection configuration must havea unique communications address. If two or morecontrols share the same address, corruptedcommunication will result.

The remote addressing capability of TapTalk andthe digital tapchanger control allows multiple controlsto share a direct or modem connection. This can bedone with standard RS-232 connections using acommunications line splitter (see Figure 9-4, MultipleControl Addressing Using Communications LineSplitter). See Chapter 3, Setting the Control formore information on specific menu commands.

A control address of zero is a “wild card” that willillicit a response from all controls on a sharedconnection and result in corrupted communication.

With these arrangements, any control can be selectedfrom within TapTalk by specifying it’s uniquecommunications address, ranging from 1 to 200.The communications address must have previouslybeen set from the control’s front panel.

9–7

TapTalk – 9

9.6 Cautions

Control and TapTalk® CompatibilityEvery attempt has been made to maintaincompatibility with previous control software versions.In some cases (most notably, with older controls),compatibility cannot be maintained. However,TapTalk should work correctly with more than oneversion of the M-2001 Series Digital TapchangerControls on a single bus, provided that the controlsare all set to use the same protocol. If there is anyquestion about compatibility, contact the factory.

Control PriorityControl conflicts will not occur as local commandsinitiated from the front panel receive priorityrecognition. While the unit is in local mode,communication via the serial ports is suspended,unless local mode is disabled. TapTalk displays anerror message to indicate this fact.

Time and Date StampingTime and date stamping of events is only as usefulas the validity of the control’s internal clock. Underthe Utilities menu, the Set Control Date/Timecommand allows you to manually set the control’sclock. For reference, the computer’s clock is alsodisplayed.

Local ModeIn the control’s configuration menu, there is anoption to enable or disable Local Mode. If LocalMode is disabled, the user may access the controlvia the local screen as well as through communicationSCADA.

Serial Port ConnectionsIf the serial port is connected to something otherthan a modem and a TapTalk modem command isexecuted, the results are unpredictable. In somecases, the computer may have to be reset.

If the computer’s communications options (baudrate, serial communications port, andcommunications address) do not match those onthe control, the control will return an error message.

Local Mode – Allows control of reading/writingsetpoints and configurations using communications.There are 4 settings associated: Disable, ReadOnly, Always Read Only, and No Read or Write.When set to Disable, read/write communication willbe available at all times. When set to Read Only,read/write communications will be available onlywhen the front panel of the control is inactive. If thefront panel is active, only reads via communicationswill be allowed. When set to Always Read Only,only reads via communications will be allowed,regardless of whether the front panel is active ornot. When set to No Read or Write, read/writecommunication will be available only when the frontpanel to the control is inactive. If the front panel isactive, no communication will be allowed.

Dead-Sync Time – This time delay improves robustoperation when communication lines are intermittent.Communication dead-sync time is the time that thecontrol will wait from the last received characterand continue without attempting to resynchronize.

Set TimersThe Set Timers menu feature initiates the displayof the Set Timers dialog box which displays thecurrent timeout values, and allows the user to changetiming values.

The Time Out setting determines time period atwhich TapTalk will stop attempting to establishcommunication with the target control.

The Wait Time setting determines the time betweenindividual commands when multiple commands arebeing performed. If errors occur, then increase thewait time setting before adjusting the timeout setting.

This feature also includes the capability to adjustthe timing (Monitoring Timer) at which TapTalk®

refreshes control monitoring screen parameters.

The Data Logging toolbar item includes ControlSetup and Download and To PC data loggingfeatures.

When connected to a M-2001C (BASE-R) controlthe Data Logging feature provides the user with theability to initiate data logging of selectable controlparameters to either the selected control fordownloading at a later time or directly to a PC.

This feature allows the user to configure theparameters that the control will use to log data, andto download the logged data to a comma separatedvalue (CSV) file or a TapPlot file. CSV files can beopened in a spreadsheet program such as MicrosoftExcel™. TapPlot flies can be viewed with TapPlot.

Data Logging/Control Setup and DownloadThis submenu item displays the Data LoggingControl Setup and Download Dialog Screen.

The Logging section allows the user to select theparameters to be logged by the control. The numberof parameters selected determines the Max TimeAvailable duration that the control can store.

In the Logging Timer section, the Sampling Periodallows the user to input the frequency in minutes atwhich the data will be logged. Max Time Availabledisplays the amount of data that can be held in thecircular memory block. This field will automaticallyupdate with any changes made in the SamplingPeriod or the Data To Be Logged section.

To erase the existing data and start logging newdata, select “Erase Existing Data and StartLogging Data to Control...”

Once the Data to be Logged parameters areuploaded to the control by selecting Erase ExistingData and Start Logging data to Control, the controlwill log data to onboard memory. Logging will continueindefinitely until a new set of log parameters areuploaded, at which point all previously logged datawill be cleared, and the control will begin loggingdata with the new parameters.

In the Downloading portion of the screen, theAvailable Range section will display the oldest andlatest dates of the logged data. These dates willalso initially appear in the Download Range sectionedit boxes, which indicate the start and end pointsfor the data to be downloaded.

The File Name text box contains the name of thefile to which the data will be downloaded. The FileType box also contains the selection which can be“.CSV”, “.TPF” or both. A “.CSV” file extension isrequired for these files so that they can be recognizedand opened by Excel or Lotus123 compatiblespreadsheet applications. A “.TPF” file extensionallows the file to be read by TapPlotTM.If an incorrectfile extension or no extension is used, TapTalk® willprompt the user to have TapTalk apply a correctextension or cancel the operation. Files saved usingduplicate file names will be overwritten withoutwarning.

▲ CAUTION: Be sure to download your data beforechanging parameters. Once the Start Logging toControl button is selected, all previously loggeddata will be cleared (and will no longer be availablefor download), and the control will begin logging newdata.

When Download is selected, all data selected inthe Download Range section will be downloaded tothe file displayed in the File’s Name section. If therange chosen includes a large amount of data, thedownload may take up to 45 minutes (300 Kb).

If necessary edit the Download Range, then selectDownload to download the data from the selectedrange.

Data Logging/To PCThe To PC submenu item displays the DataLogging to PC Dialog Screen ( Figure 9-26). TheTo PC feature enables the user to store selectedparameter data for review at a later time. One ormore of the parameters listed in the Data To BeLogged section can be selected for logging. Thetime displayed in the Sampling Period in theLogging Options section determines how frequentlydata samples are acquired, ranging from 1 minute toa maximum of 9999 minutes. The duration ofsampling is further regulated by the SamplingDuration which restricts data logging to a maximumof 9999 hours or 9999 days. Uninterruptedcommunication with the control is required whiledata is being logged.

Data logging is initiated by selecting Start DataLogging to PC. The Start Data Logging to PC isreplaced by Stop Data Logging to PC dialog toindicate data logging is active. Logging can becanceled either by choosing the Stop Data Loggingto PC command or by interrupting communication.

The Set File Name selection allows the user toname the file to which data is saved. If the SuggestedFile Name feature is disabled, then a file name willbe reguired to be entered with a default file extensionof *.CSV, (Comma Separated Values is the defaultfor files with data logging information). If theSuggested File Name is enabled, then the file namewill be determined by the settings from the SuggestedFile Name window with a filename extension of“.CSV”. If the user saves a file using a duplicatefilename, the previously saved file will be overwrittenwithout warning. The size of the file must not exceedavailable disk space. The file format “.CSV” can beopened by most spreadsheet applications, allowingthe user to analyze the collected data.

This time delay improves robust operation when communicationlines are intermittent. Communication dead-sync time is the timethat the control will wait from the last received character andcontinue without attempting to resynchronize. Factory setting is 50msec; range is 0-32000 msec.

Allows control of reading/writing setpoints and configurations viacommunications. There are 4 settings associated: Disable, ReadOnly, Always Read Only, and No Read or Write. When set to Disable,read/write communication will be available at all times. When set toRead Only, read/write communication will be available only whenthe front panel of the control is inactive. If the front panel is active,only reads via commmunications will be allowed. When set toAlways Read Only, only reads via communications will be allowedregardless of whether the front panel is active or not. When set to NoRead or Write, read/write commmunication will be available onlywhen the front panel fo the control is inactive. If the front panel isactive, no communications will be allowed.
