DVC2000 Series

September 20061-2

Instrument DescriptionDVC2000 Series digital valve controllers arecommunicating, microprocessor-basedcurrent-to-pneumatic valve positioners (see figure1-1). They are designed to replace standardpneumatic and electro-pneumatic valve positioners.

In addition to the traditional function of converting aninput current signal (4−20mA) to a pneumatic outputpressure, the DVC2000 Series digital valve controllerscommunicate via a local display panel and/or via theHART� protocol. An option is available which providesisolated circuitry for two (2) integrated limit switches(for open/close valve indication) and a valve positiontransmitter (for separate valve position feedback).

TerminologyInstrument Level� There are four (4) levels offunctionality available: AC, HC, AD and PD.

AC� This level provides the capability to setup andcalibrate the positioner through the LCD or the 375Field Communicator.

HC� This level provides additional capability foradvanced configuration of the positioner (such astravel limits/cutoffs, custom characterization, andminimum open/closing time). Also, information isavailable through the HART protocol for diagnosticalerts such as travel deviation, cycle count, andtravel accumulation.

AD� This level provides advanced diagnosticcapabilities for performance testing. When used withAMS ValveLink Software, instrument health can beevaluated with tests such as Valve Signature, stepresponse and dynamic error band. The softwareprogram provides detailed analysis with graphics.

PD� This level provides automated, non-intrusivetesting of the operating performance of the controlvalve assembly. When used with AMS� ValveLink�

Software, tests to isolate component degradationcan be run on the valve assembly without affectingthe process.

Local Interface� All DVC2000 Series digital valvecontrollers come standard with a Liquid CrystalDisplay (LCD) and four (4) pushbuttons. The localinterface provides the capability to setup and calibratethe positioner and view basic diagnostic messages.

Figure 1-1. Type DVC2000 Series Digital Valve Controller

W8755

Magnet Assembly� This is the feedback componentthat is mounted directly to the valve stem. It supplies amagnetic field that is sensed by the digital valvecontroller.

Option Boards� The DVC2000 Series digital valvecontroller is available with two (2) limit switches and avalve position transmitter. The option boards includethe additional circuitry and terminations that arerequired to support these output signals.

Pole Piece� Inserted into the DVC2000 housing andprotruding through the back of the instrument is atwo-pronged fork that houses the magnetic sensor forposition feedback.

Scope of ManualThis instruction manual includes specifications,installation, initial setup, configuration, operation,troubleshooting, and maintenance information forDVC2000 Series digital valve controllers.

This manual describes using the Model 375 FieldCommunicator to setup and calibrate the instrument.To accomplish these functions, as well as diagnosticand performance tests with AMS ValveLink Software,refer to the AMS ValveLink Software help.

No person may install, operate, or maintain aDVC2000 Series digital valve controller without first being fully trained and qualified in valve, actuator andaccessory installation, operation and maintenance,and carefully reading and understanding thecontents of this manual. If you have any questionsregarding these instructions, contact your EmersonProcess Management� sales office beforeproceeding.

Valve / Actuator Mounting If ordered as a part of a control valve assembly, thefactory will mount the digital valve controller on theactuator and calibrate the instrument. If you purchasedthe digital valve controller separately, you will need amounting kit to mount the digital valve controller on theactuator. The following procedures are generalguidelines you should consider when mounting the

digital valve controller. See the instructions that comewith the mounting kit for detailed information onmounting the digital valve controller to a specificactuator model.

The DVC2000 housing is available in four differentconfigurations, depending on the actuator mountingmethod and threaded connection style. Figure 2-1shows the available configurations.

The feedback system for the Type DVC2000 Seriesdigital valve controller utilizes a magnetic field for truelinkage-less, non-contacting position measurement. Inorder to prevent inadvertent stem movement while theinstrument is in operation, magnetic tools (such as amagnetic-tipped screwdriver) should not be used.

CAUTION

The magnet material has beenspecifically chosen to provide along-term stable magnetic field.However, as with any magnet, caremust be taken when handling themagnet assembly. Another highpowered magnet placed in closeproximity (less than 25 mm) can causepermanent damage. Potential sourcesof damaging equipment: transformers,DC motors, stacking magnet arrays,magnetic tipped screwdrivers.

DVC2000 Series

September 20062-4

NoteAs a general rule, do not use less than50% of the magnet array for full travelmeasurement. Performance willdecrease gradually as the array isincreasingly subranged.

The linear magnet arrays have a validtravel range indicated by arrowsmolded into the piece. This means thatthe hall sensor (on the back of theDVC2000 housing) has to remainwithin this range throughout the entirevalve travel. See figure 2-2.

The linear magnet arrays aresymmetrical. Either end may be up.

There are a variety of mounting brackets and kits thatare used to mount the DVC2000 to different actuators.However, despite subtle differences in fasteners,brackets, and connecting linkages, the procedures formounting can be categorized as follows:

Air-to-open sliding stem (linear) actuators.

Air-to-close sliding stem (linear) actuators.

Air-to-open Fisher GX actuator.

Air-to-close Fisher GX actuator.

Rotary actuators with travel up to 90 degrees.

See figure 2-3 for the different travel feedback magnetassemblies.

Air-to-Open Sliding Stem (Linear)Actuators (e.g. Fisher Type 667)

WARNING

Refer to the Installation WARNING atthe beginning of this section.

1. Attach the mounting bracket to the actuator.

2. Loosely attach the feedback pieces and magnetassembly to the valve stem connector. Do not tightenthe fasteners because fine adjustment is required.

WARNING

Severe personal injury or propertydamage may occur from processinstability if the instrument air supplyis not clean, dry and oil-free. Whileuse and regular maintenance of afilter that removes particles larger that40 microns in diameter will suffice inmost applications, check with aEmerson Process Management fieldoffice and industry instrument airquality standards for use withcorrosive air or if you are unsureabout the proper amount or methodof air filtration or filter maintenance.

Supply pressure must be clean, dry air or noncorrosiveand nonflammable gas that meets the requirements ofANSI/ISA Standard 7.0.01.

A Fisher Type 67CFR filter regulator, or equivalent,may be used to filter and regulate supply air. Ifpressure regulation is not required, a Fisher TypeP594 filter may be used.

Connect the nearest suitable supply source to theconnection with the arrow pointing towards theopening (see figure 2-7).

Electrical Connections

WARNING

Select wiring and/or cable glands thatare rated for the environment of use(hazardous area, ingress protectionand temperature). Failure to useproperly rated wiring and/or cableglands can result in personal injury orproperty damage from fire orexplosion.

The digital valve controller is normally powered by acontrol system output card. The use of shielded cablewill ensure proper operation in electrically noisyenvironments. Wire size requirements are 14 AWGmaximum, 26 AWG minimum.

Be sure to follow the appropriate I.S. circuit guidelineswhen installing field wiring to the loop terminals as wellas the limit switch and transmitter terminals.

Wire the digital valve controller as follows:

1. Remove the main instrument cover.

2. Route the field wiring into the terminal box throughthe conduit connection. When applicable, installconduit using local and national electrical codes thatapply to the application.

3. Connect the control system output card positivewire �current output� to the +11 terminal. Connect thecontrol system output card negative (or return) wire�current output� to the −12 terminal.

4. Two ground terminals are available for connectinga safety ground, earth ground, or drain wire. Theseground terminals are electrically identical. Makeconnections to these terminals following national andlocal codes and plant standards.

5. Replace the cover if the local interface is not beingused for configuration or calibration.

Options Boards All three options circuits (transmitter, switch 1 andswitch 2) control current from an external powersource similar to the operation of a 2-wire transmitter.

Limit Switches On units that are supplied with integral limit switches,additional terminals provide the field wiring connectionpoint. The limit switches are isolated from each otherand from the digital valve controller�s primaryfeedback. If only one switch is to be used, you mustuse channel 1. Although electrically isolated perIntrinsic Safety requirements, channel 2 derives itspower from channel 1. Therefore channel 2 cannot beused alone.

Wire the limit switches as follows:



3. Connect the control system input card positive wire�switch input� to the +41 terminal. Connect the controlsystem input card negative wire �switch input� to the−42 terminal. Refer to figure 2-13.

4. If a second switch is to be used, connect thecontrol system input card positive wire �switch input� tothe +51 terminal. Connect the control system inputcard negative wire �switch input� to the −52 terminal.

5. Proceed to the Basic Setup section to configure theswitch action.6. Replace the cover if the local interface is not beingused for configuration or calibration.

Position Transmitter On units that are supplied with an integral valveposition transmitter, additional terminals provide thefield wiring connection point. The position transmittercircuit in the DVC2000 derives it�s operating power

Vent By design, the instrument exhausts supply air into thearea under the cover. The vent should be left open toprevent pressure buildup under the cover and to drainany moisture that may accumulate in the housing. Thecontrol valve assembly should be installed such thatthe primary vent provides gravitational draining.

If a remote vent is required, the vent line must be asshort as possible with a minimum number of bendsand elbows.

Communications Connections A HART communicating device, such as a Model 375Field Communicator or a personal computer runningAMS ValveLink Software communicating through aHART modem, interfaces with the DVC2000 Seriesdigital valve controller. You can connect at any pointon the 4−20 mA loop. Alternatively, convenienttermination points are located on the termination board(figure 2-13). The instrument must be powered beforedigital communication will commence. 2

Tuning

WARNING

Changes to the tuning set may causethe valve/actuator assembly to stroke.To avoid personal injury and propertydamage caused by the release ofpressure or process fluid, providesome temporary means of control forthe process.

To manually tune the instrument or automatically tunethe instrument without changing the calibration values,the TUNING routine is available. To access thisprocedure from the home screen, press the DOWN(�) arrow key three times and then the RIGHT (�)

arrow key once. From there follow the prompts asillustrated in figure 3-5 below.

Automatic tuning will provide status information as theprocedure is running. Manual tuning will require you toinput values. This procedure is only recommendedwhen the automatic tuning procedure results in failure.

A typical starting point for most small actuators is �C�Using the UP (�) and DOWN (�) arrow keys willapply the values immediately. You can then changethe input current to observe the response. When youare satisfied with the response, press the RIGHT (�)arrow key to fine tune the instrument. The UP (�) andDOWN (�) arrow keys will apply more or lessdamping to fine tune the overshoot after a step inputchange.

After manual tuning is complete, you will have thechoice to save the tuning data or exit the procedurewithout saving. If you exit without saving, the lastsaved tuning data will be restored.

Detailed Setup If the factory default configuration values need to bechanged, the DETAILED SETUP procedure providesaccess. See figure 3-6 for the flowchart showing thesequence of screens. To access this procedure fromthe home screen, press the DOWN (�) arrow key fourtimes. The RIGHT (�) arrow key brings you into theconfiguration items. Once you are in a particularconfiguration item, use the UP (�) and DOWN (�)arrow keys to select the appropriate choice.

To exit this procedure, press the RIGHT (�) arrow keyand view the remaining configuration items until youreach the exit screen. If you exit without saving, thelast saved configuration data will be restored.

Below is an explanation of the configuration items.

Zero Control Signal�Identifies whether the valve isfully OPEN or fully CLOSED when the input is 0%. Ifyou are unsure how to set this parameter, disconnectthe current source to the instrument. The resultingvalve travel is the Zero Control Signal. Thiscorresponds to setting the output pressure to zero.

Pressure Units�Defines the pressure units in eitherPSI, BAR, or KPA.

Input Range Low�This will correspond to 0% travel ifthe Zero Control Signal is configured as closed. If theZero Control Signal is configured as open, this willcorrespond to 100% travel.

Input Range High�This will correspond to 100% travelif the Zero Control Signal is configured as closed. If theZero Control Signal is configured as open, this willcorrespond to 0% travel.

Characteristic�Defines the relationship between thetravel target and the ranged set point. Ranged setpoint is the input to the characterization function. If theZero Control Signal is closed, then a set point of 0%corresponds to a ranged input of 0%. If the ZeroControl Signal is open, a set point of 0% correspondsto a ranged input of 100%. Travel target is the outputfrom the characterization function.

NoteTravel cutoffs are enabled by defaulton all units.

The factory default characteristic is LINEAR. You canalso use a QUICK OPEN, EQUAL %, or CUSTOMfunction. However, the custom function is initiallyconfigured linear, unless you use a HART based hostto reconfigure the custom points. Custom configurationcan be selected, but the curve can not be modifiedwith the local interface.

Transmitter�This configures the relationship betweenthe valve travel and the position transmitter outputsignal. If you select CLOSED, the transmitter will send4 mA when the valve is closed. If you select OPEN,the transmitter will send 4 mA when the valve is open.

A switch is located on the options board to select thetransmitter fail signal (high+ or low−). High+ will resultin a current output of > 22.5 mA upon transmitterfailure. Low− will result in a current output of < 3.6 mA.Refer to figure 3-7 for location and switch selection.

Switch #1 Trip Point�Defines the threshold for thelimit switch wired to terminals +41 and −42 in percentof calibrated travel.

Switch #1 Closed�Configures the action of the limitswitch wired to terminals +41 and −42. SelectingABOVE configures the switch to be closed when thetravel is above the trip point. Selecting BELOWconfigures the switch to be closed when the travel isbelow the trip point. Selecting DISABLED removes theicons and status from the display.

Switch #2 Trip Point�Defines the threshold for thelimit switch wired to terminals +51 and −52 in percentof calibrated travel.

Switch #2 Closed�Configures the action of the limitswitch wired to terminals +51 and −52. SelectingABOVE configures the switch to be closed when the

Diagnostic Messages, Codes andDetailsThe DVC2000 series digital valve controller isconstantly diagnosing itself for abnormal conditionswhile powered-up. The following messages will appearon the local user interface if a fault condition exists(identified on the default screen by the alert symbol

! ).

SWITCH 1 ???SWITCH 2 ???�The alert symbol in conjunction withthe above text indicates that limit switch circuit 1 is notpowered, or at least one of the switches is enabled. Inorder for either of the switches to work, switch circuit 1must be powered. Switch 2 cannot be used alone. Toeliminate the alert symbol, you can either apply 5 to 30VDC to switch circuit 1 or disable both switches (referto the Installation section).

Once switch circuit 1 is powered properly, questionmarks (???) will indicated that the correspondingswitch is disabled.

Shutdown Activated� This screen appears if thepositioner has shut down and no air is being deliveredto the actuator. Therefore, the valve is at its fail-safeposition. An example of a source of this error is corruptfirmware code upon start-up. The factory defaultsetting for this error is disabled. Therefore, this alertwill only be enabled by actively configuring it with aHART based host (eg. Field Communicator, AMSValveLink Software).

Travel Deviation� This error message indicates thatthere is a difference between the input signal (aftercharacterization) and the actuator travel reading fromthe position feedback element. The default setting is7% for 5 seconds. These settings can be configuredthrough a HART communicating host on any HC tier orhigher. Possible sources of this error are insufficientair supply or excessive valve friction.

Replace Main Board� A problem with the electronicshas been detected. Sources of this error may includehardware or firmware problems. If this error is

detected, the instrument may be operational, butperformance will be degraded.

Check Mounting� The valve position feedbackreading is valid, but it is outside the operating range.Sources of this error include loose or bent mountingbrackets or a misaligned magnet array. This error doesnot identify faulty components, but rather faultyinstallation or alignment. This alert is also called aTravel Sensor Failure.

Check Supply� The valve is not able to reach itstarget position due to insufficient supply pressure. Thiserror will most likely occur in conjunction with theTravel Deviation error.

Check I/P Converter� A problem relating to the I/Pconverter has been detected. Sources of this errorinclude:

Electronics problems indicated by the drivecurrent read back being out of range

Low supply pressure indicated by an active drivesignal alert

A stuck valve resulting in integrator wind-up.

Device Locked by HART� Another HART host (e.g. AMS ValveLink Software, AMS Suite: IntelligentDevice Manager, or the 375 Field Communicator) iscommunicating with the DVC2000. Typically thismeans that the instrument is �out of service�.

Pressure = ???�The actuator pressure reading isgreater than 125% of the configured maximum supplypressure. For example, if the supply pressure rangewas set to 35 psi and the actual supply pressure was45 psi, you will see ???�s when the DVC2000 isdelivering full supply pressure to the actuator. If youreduce the supply pressure, or stroke the valve closed(air-to-open/fail closed setup), eventually there will bea point where numerical values appear.

This configuration parameter can be changed throughthe Field Communicator (1-1-2-2-3) or AMS ValveLinkSoftware (Detailed Setup − Pressure).

Control Mode You can change the control mode by selecting ControlMode from the Mode menu, or press the Hot Key andselect Control Mode.

Control Mode lets you define where the instrumentreads its set point. Follow the prompts on the FieldCommunicator display to choose one of the followingcontrol modes: Analog or Digital.

Choose Analog if the instrument is to receive its setpoint over the 4�20 mA loop. Normally the instrumentcontrol mode is Analog.

Choose Digital if the instrument is to receive its setpoint digitally, via the HART communications link.

A third mode, Test, is also displayed. Normally theinstrument should not be in the Test mode. The FieldCommunicator automatically switches to this modewhenever it needs to stroke the valve, for exampleduring calibration or stroke valve. However, if youabort from a procedure where the instrument is in theTest mode, it may remain in this mode. To take theinstrument out of the Test mode, select Control Modethen select either Analog or Digital.

Restart Control Mode Restart Control Mode (Restart Ctrl Mode) lets youchoose which operating mode you want the instrumentto be in after a restart. Follow the prompts on the FieldCommunicator display to define the restart controlmode as Resume Last, Analog, or Digital.

Burst ModeEnabling burst mode provides continuouscommunication from the digital valve controller. Burstmode applies only to the transmission of burst modedata (analog input, travel target, pressure, and travel)and does not affect the way other data is accessed.

Access to information in the instrument is normallyobtained through the poll/response of HARTcommunication. The Model 375 Field Communicatoror the control system may request any of theinformation that is normally available, even while theinstrument is in burst mode. Between each burst modetransmission sent by the instrument, a short pauseallows the Field Communicator or control system toinitiate a request. The instrument receives the request,processes the response message, and then continues�bursting� the burst mode data.

There are four burst mode commands. Command 3 isrecommended for use with the Rosemount� Model333 HART Tri-Loop� HART-to-analog signalconverter. The other three are not used at this time.

Command 3 provides the following variables:

Primary variable�analog input in % or mA,

Secondary variable�travel target (valve setpoint) in % of ranged travel,

Tertiary variable�output pressure in psig, bar, orkPa.

Quaternary variable�travel in % of rangedtravel.

To enable burst mode, from the Online menu, selectSetup & Diag, Detailed Setup, Mode, Burst, and BurstEnable. To send a burst mode command, select Setup& Diag, Detailed Setup, Mode, Burst, and BurstCommand. Burst mode must be enabled before youcan change the burst mode command.

Restarting the Instrument Restart resets the instrument in the same manner aswhen power to the instrument is interrupted. WhenRestart is issued, all of the newly entered configurationvariables become active. Otherwise, they may nottake effect until the instrument is placed In Service.

Setting Protection Some setup parameters may require changing theprotection with the Field Communicator.

Two levels of protection are available:

Config & Calib�Both setup and calibration areprotected. Prohibits changing calibration and protectedsetup parameters.

None�Neither setup nor calibration is protected.Allows changing calibration and setup parameters.

Table 4-2 lists configurable parameters in theinstrument and the requirements for modifying theseparameters, in terms of instrument mode andprotection.

To change an instrument�s protection, press the Hotkey on the Field Communicator display windowand select Protection or select Protection from theDetailed Setup menu. Select the desired level ofprotection. Follow the prompts on the FieldCommunicator display to set the protection level.

HART Tag�Enter an up to 8 character HARTtag for the instrument. The HART tag is the easiestway to distinguish between instruments in amulti-instrument environment. Use the HART tag tolabel instruments electronically according to therequirements of your application. The tag you assign isautomatically displayed when the Field Communicatorestablishes contact with the digital valve controller atpower-up.

Message�Enter any message with up to 32characters. Message provides the most specificuser-defined means for identifying individualinstruments in multi-instrument environments.

Descriptor�Enter a descriptor for the applicationwith up to 16 characters. The descriptor provides alonger user-defined electronic label to assist with morespecific instrument identification than is available withthe HART tag.

Date�Enter a date with the format MM/DD/YY.Date is a user-defined variable that provides a place tosave the date of the last revision of configuration orcalibration information.

Valve Serial Num�Enter the serial number forthe valve in the application with up to 12 characters.

Inst Serial Num�Enter the serial number on theinstrument nameplate, up to 12 characters.

Polling Address�If the digital valve controller isused in point-to-point operation, the Polling Address is0. When several devices are connected in the sameloop, such as for split ranging, each device must beassigned a unique polling address. The Polling

Address is set to a value between 0 and 15. Tochange the polling address the instrument must beOut Of Service.

For the Field Communicator to be able tocommunicate with a device whose polling address isnot 0, it must be configured to automatically search forall or specific connected devices. For information onconfiguring the Field Communicator for automaticpolling, see the Model 375 Field Communicator Basicssection, Appendix C.

LUI Language�Select the language to bedisplayed on the local user interface; English, French,German, Italian, Spanish, Chinese and Japanese.

Measured Variable Units and RangesTo define the measured variable units and ranges,select Setup & Diag, Detailed Setup, and MeasuredVar. Follow the prompts on the Field Communicatordisplay to enter or view information in the followingfields: Analog Input Unit, Analog In Range Hi (AnalogInput Range High), Analog In Range Lo (Analog InputRange Low) Pressure Units, LUI Pressure Units, andTemp Units (Temperature Units).

Analog Input Units�Permits defining the AnalogInput Units in mA or percent of 4−20 mA range.

Analog In Range Hi�Permits setting the InputRange High value. Input Range High shouldcorrespond to Travel Range High, if the Zero ControlSignal is configured as closed. If the Zero ControlSignal is configured as open, Input Range Highcorresponds to Travel Range Low. See figure 4-1.

LUI Pressure Units�Enter the pressure unitsdisplayed on the local user interface; psi, bar, or kPa.

Temp Units�Degrees Fahrenheit or Celsius.The temperature measured is from a sensor mountedon the digital valve controller�s printed wiring board.

Actuator and Valve Information Select Setup & Diag, Detailed Setup, and Actuator &Valve. Follow the prompts on the Field Communicatordisplay to enter or view information in the followingfields: Max Supply Press (Maximum Supply Pressure),Actuator Style, Valve Style, and Zero Ctrl Signal (ZeroControl Signal).

Max Supply Press�Enter the maximum supplypressure in psi, bar, or kPa, depending on what wasselected for pressure units.

NoteIf the actual measured pressureexceeds this setting by 25%, thepressure measurement will not bedisplayed.

Actuator Style�Enter the actuator style, springand diaphragm, piston double-acting without spring,

piston single-acting with spring, or piston double-actingwith spring.

Valve Style�Enter the valve style, rotary orsliding-stem

Zero Ctrl Signal�Identifies whether the valve isfully open or fully closed when the input is 0%. If youare unsure how to set this parameter, disconnect thecurrent source to the instrument. The resulting valvetravel is the Zero Control Signal. (With direct actingdigital valve controllers, disconnecting the currentsource is the same as setting the output pressure tozero.)

Setting Response Select Setup & Diag, Detailed Setup, and ResponseControl. Follow the prompts on the FieldCommunicator display to configure the followingresponse control parameters: Tuning Set, DampingFactor, Expert Tuning Gains, Input Char (InputCharacteristic), Set Pt Filter Time (Set Point FilterTime), Min Open/Close (Minimum Opening Time /Minimum Closing Time), and Integral Settings.

WARNING


Tuning Set�There is a choice of tuning sets tochoose from. Each tuning set provides a preselectedvalue for the digital valve controller gain settings.Tuning set C provides the slowest response and Mprovides the fastest response.

Damping Factor�If after selecting a tuning setthe valve travel overshoot is excessive orunsatisfactory, the damping factor allows you to eitherdecrease damping to allow more overshoot, orincrease damping to decrease the overshoot.

Expert Tuning Gains�With Expert Tuning, youcan specify the proportional gain, velocity gain, andminor loop feedback gain.

Input Char�Defines the relationship between thetravel target and ranged set point. Ranged set point isthe input to the characterization function. If the zero

4

DVC2000 Series

September 20064-8

control signal equals closed, then a set point of 0%corresponds to a ranged input of 0%. If the zerocontrol signal equals open, a set point of 0%corresponds to a ranged input of 100%. Travel targetis the output from the characterization function.

To select an input characterization, choose SelectInput Char from the Input Char menu. You can selectfrom the three fixed input characteristics shown infigure 4-2 or you can select a custom characteristic.Figure 4-2 shows the relationship between the traveltarget and ranged set point for the fixed inputcharacteristics, assuming the Zero Control Signal isconfigured as closed.

You can specify 21 points on a custom characteristiccurve. Each point defines a travel target, in % ofranged travel, for a corresponding set point, in % ofranged set point. Set point values range from −6.25%to 106.25%. Before modification, the customcharacteristic is linear.

To define a custom input characteristic, from the InputChar menu select Define Custom Char. Select thepoint you wish to define (1 to 21), then enter thedesired set point value. Press Enter then enter thedesired travel target for the corresponding set point.When finished, select point 0 to return to the InputChar menu.

With input characterization you can modify the overallcharacteristic of the valve and instrument combination.Selecting an equal percentage, quick opening, orcustom (other than the default of linear) inputcharacteristic modifies the overall valve andinstrument characteristic. However, if you select thelinear input characteristic, the overall valve andinstrument characteristic is the characteristic of thevalve, which is determined by the valve trim (i.e., theplug or cage).

Set Point Filter Time�Time constant for the setpoint filter, in seconds. The set point filter slows theresponse of the digital valve controller and is typicallyused with noisy or fast processes. The filter providesimproved closed loop process control. To disable thefilter, set the time constant to 0 seconds.

Min Opening Time�Minimum Opening Time isconfigured in seconds and defines the minimum timefor the travel to increase the entire ranged travel. Thisrate is applied to any travel increases. A value of 0.0seconds deactivates this feature and allows the valveto stroke open as fast as possible.

Min Closing Time�Minimum Closing Time isconfigured in seconds and defines the minimum timefor the travel to decrease the entire ranged travel. Thisrate is applied to any travel decreases. A value of 0.0

Integral Gain�By setting this value to 0.0 thepositioner integrator is disabled. Any other value willprovide reset action to improve static performance.

Integral Dead Zone�When the travel target andactual target deviate by less than this amount, theintegrator is automatically disabled. This prevents thepositioner integrator from fighting with the processcontroller integrator which may result in valveoscillation.

Setting Travel Limits and Cutoffs Select Setup & Diag, Detailed Setup, ResponseControl, and Limits & Cutoffs. Follow the prompts onthe Field Communicator display to set the Tvl LimitHigh (Travel Limit High), Tvl Limit Low (Travel LimitLow), Tvl Cutoff High (Travel Cutoff High), and TvlCutoff Low (Travel Cutoff Low).

Tvl Limit High�Travel Limit High defines the highlimit for the travel in percent (%) of ranged travel. It isthe maximum allowable travel (in percent of rangedtravel) for the valve. During operation, the travel targetwill not exceed this limit. When a Travel Limit High isset, the Travel Cutoff High is deactivated, since onlyone of these parameters can be active. Travel LimitHigh is deactivated by setting it to 125.0%.

Tvl Limit Low�Travel Limit Low defines the lowlimit for the travel in percent (%) of ranged travel. It isthe minimum allowable travel (in percent of rangedtravel) for the valve. During operation, the travel targetwill not exceed this limit. When a Travel Limit Low isset, the Travel Cutoff Low is deactivated, since onlyone of these parameters can be active. Travel LimitLow is deactivated by setting it to −25.0%.

Tvl Cutoff High�Travel Cutoff High defines thehigh cutoff point for the travel in percent (%) of rangedtravel. Above this cutoff, the travel target is set to123.0% of the ranged travel. When a Travel CutoffHigh is set, the Travel Limit High is deactivated, sinceonly one of these parameters can be active. TravelCutoff High is deactivated by setting it to 125.0%.

Tvl Cutoff Low�Travel Cutoff Low defines thelow cutoff point for the travel. Travel Cutoff Low canbe used to ensure proper seat load is applied to thevalve. When below the travel cutoff low, the output isset to zero or to full supply pressure, depending uponthe zero control signal. A Travel Cutoff Low of 0.5% isrecommended to help ensure maximum shutoff seatloading.

When a Travel Cutoff Low is set, the Travel Limit Lowis deactivated, since only one of these parameters canbe active. Travel Cutoff Low is deactivated by setting itto −25.0%.

Switch 1 Closed�Configures the action of thelimit switch wired to terminals +41 and −42. SelectingABOVE configures the switch to be closed when thetravel is above the trip point. Selecting BELOWconfigures the switch to be closed when the travel isbelow the trip point. Selecting DISABLED removes theicons and status from the display.

Switch 2 Trip Point�Defines the threshold for thelimit switch wired to terminals +51 and −52 in percentof calibrated travel.

Switch 2 Closed�Configures the action of thelimit switch wired to terminals +51 and −52. SelectingABOVE travel is above the trip point. SelectingBELOW configures the switch to be closed when thetravel is below the trip point. Selecting DISABLEDremoves the icons and status from the display.

NoteSwitch #2 is only operational if poweris applied to switch #1 also. Switch #2cannot be used alone.

Transmitter Action�This configures therelationship between the valve travel and the positiontransmitter output signal. If you select CLOSED, thetransmitter will send 4 mA when the valve is closed. Ifyou select OPEN, the transmitter will send 4 mA whenthe valve is open.

A switch is located on the options board to select thetransmitter fail signal (high+ or low−). High+ will resultin a current output of > 22.5 mA upon transmitterfailure. Low− will result in a current output of < 3.6mA. Refer to figure 3-7 for location and switchselection.

Tuning

WARNING


Automatic The auto tuner is used to optimize digital valvecontroller tuning. It can be used on most sliding-stemand rotary designs, including Fisher and othermanufacturers� products. Moreover, because the autotuner can detect internal instabilities before theybecome apparent in the travel response, it cangenerally optimize tuning more effectively than manualtuning.

Access the auto tuner by selecting Auto Tuner fromthe Calibrate menu. Follow the prompts on the FieldCommunicator display to optimize digital valvecontroller tuning.

ManualIf the auto tuner does not provide the desiredresponsiveness, you can manually tune the DVC2000.Refer to Setting Response, page 4-7.

Calibration

WARNING

During calibration the valve will movefull stroke. To avoid personal injuryand property damage caused by therelease of pressure or process fluid,provide some temporary means ofcontrol for the process.

NoteIf optional limit switches are beingused, power must be applied to theswitch circuits throughout thecalibration routine.

and output bias. By searching for the end points, theinstrument establishes the limits of physical travel, i.e.,the actual travel 0 and 100% positions. This alsodetermines how far the relay beam swings to calibratethe sensitivity of the beam position sensor.

Adjusting the minor loop feedback bias is done aroundmid travel. The valve position is briefly moved backand forth to determine the relay beam position atquiescence. Essentially, it establishes the zero pointfor the Minor Loop Feedback circuit. The back andforth motion is performed to account for hysteresis.

Adjusting the output bias aligns the travel set pointwith the actual travel by computing the drive signalrequired to produce 0% error. This is done while thevalve is at 50% travel, making very small adjustments.

Figure B-1. DVC2000 Series Digital Valve Controller Block Diagram

DVC2000 Operation The DVC2000 series digital valve controller uses atraditional 4−20mA input signal and converts it into apneumatic output pressure that is delivered to thecontrol valve actuator. Accurate control of the positionof the valve is enabled by valve stem positionfeedback. The way in which the DVC2000accomplishes this is through a two-stage positionerdesign. Refer to figure B-1 for a block diagram of thepositioner operation.

A traditional 4−20 mA signal provides the set point andpower to the instrument. At the same time, the HARTprotocol provides instrument and process data throughdigital communications. The instrument receives thisset point and positions the valve where it needs to be.

The input signal provides electrical power andthe set point simultaneously. It is routed into theterminal board through a twisted pair of wires. Theterminal board contains the termination points for theloop signal (+11/−12). If the options board is installed,an additional options board set includes additionalterminals for the transmitter output (+31/−32), switch#1 output (+41/−42), and switch #2 output (+51/−52).

The input signal is then directed to the mainelectronics board assembly where the microprocessorruns a digital control algorithm resulting in a drivesignal to the I/P converter.

The I/P converter assembly is connected tosupply pressure and converts the drive signal into apressure signal. The I/P converter is the pre-amplifierstage in the two-stage positioner design. Thiscomponent enables high static gain forresponsiveness to small changes in the input signal.

The I/P output is sent to the pneumatic relayassembly. The relay is also connected to supplypressure and amplifies the small pressure signal fromthe I/P converter into a larger pneumatic outputsignal used by the actuator. The pneumatic relay isthe power amplifier stage in the two-stage positionerdesign. This component enables superior dynamicperformance with minimal steady-state airconsumption.

A sensor on the printed wiring board measuresthe motion of the small valve inside the pneumaticrelay. This measurement is used for minor loopfeedback to the control algorithm resulting in stable,robust tuning.

The change in relay output pressure to theactuator causes the valve to move.

Valve position is sensed through the non-contact,linkage-less feedback sensor. There are no movinglinkages and the DVC2000 is physically separatedfrom the valve stem through the use of a magneticHall effect sensor. A magnetic array is mounted to the

B


September 2006 B-3

valve stem and the sensor is embedded in theDVC2000 housing. The sensor is electricallyconnected to the printed wiring board to provide atravel feedback signal used in the control algorithm.

The valve continues to move until the correct positionis attained.

Troubleshooting

What is a healthy unit?In order to troubleshoot the DVC2000 series digitalvalve controller, it is critical to understand how ahealthy unit is supposed to behave. Below is a list ofbehaviors you should see if the instrument isperforming well.

LCD correctly displaying characters

Pushbuttons allow navigation

Valve travels full stroke

No diagnostics messages

No alerts or alarms

Hall sensor within the valid range of travel on themagnet array

Slight audible air venting

Minimal overshoot

Quick response

Functionality matches the tier level

What are the observable symptoms?The next thing to do is to identify the symptoms of theunhealthy unit. Are there any obvious discrepanciesthat can be identified? Work through the followingitems to help gather information about the faultybehavior and identify the core problem(s).

1. Check the relay pressure range.

There are two available relays for the DVC2000:

Low pressure: 0−3.4 bar (0−49 psi) � white label

High pressure: 3.5−7 bar (50−100 psi) � greenlabel

The supply pressure feeding the instrument must fallwithin the rated pressure range of the installed relayfor proper operation.

2. Check the instrument protection (LCD viapushbuttons and Configure/Calibrate via HART)

3. Check for local device diagnostic messages

4. Check the alerts via HART

5. Check the feedback setup

Is the pole piece on the DVC2000 housing within thevalid travel range of the feedback array?

6. Observe the stem movement and pressure delivery

Determine the logical causes.With the discrepancies identified, logic can now beapplied to isolate the component that is in need ofrepair or replacement. There are seven maincategories of problems:

1. Wiring and Terminations

2. Air Supply

3. Electronics

4. Firmware

5. Pneumatics

6. Travel feedback

7. Mounting

Repair or replace the faulty components.By isolating the problem to one of these categories,component replacement or repair becomes simple andstraightforward. Refer to section 5 for componentreplacement instructions.

Checking Voltage Available

WARNING

Personal injury or property damagecaused by fire or explosion may occurit this test is attempted in any areawhich contains a potentially explosiveatmosphere or has been classified ashazardous.

To check the Voltage Available at the instrument,perform the following:

1. Disconnect the field wiring from the control systemand connect equipment as shown in figure B-2 to thecontrol system terminals.�

Menu StructureThe Field Communicator is generally used in twoenvironments: offline (when not connected to aninstrument) and online (connected to an instrument).

Offline Operation Selecting HART Application when not connected to aFIELDVUE instrument causes the Field Communicatorto display the message �No device found at address 0.Poll?� Selecting �Yes� or �No� will bring you to theHART Application menu. Three choices are availablefrom this screen: Offline, Online and Utility. The Offlinemenu allows you to create offline configurations, aswell as view and change device configurations storedon the 375 Field Communicator. The Utility menuallows you to set the polling option, change thenumber of ignored status messages, view theavailable Device Descriptions, perform a simulation,and view HART diagnostics.

Saving Setup and Calibration DataYou can upload setup and calibration data from theDVC2000 Series digital valve controller and save it inthe Field Communicator Internal Flash or aConfiguration Expansion Module. From the Offlinemenu you can then download this data to multipledevices so that they all contain the same setup andcalibration data. You can also edit the saved data.

You upload setup and calibration data from the Onlinemenu. This requires that the Field Communicator beconnected to a digital valve controller powered by a 4to 20 mA source. To save data from any Online menuselect the SAVE key. Follow the prompts on the FieldCommunicator to save the data to the Internal Flash orthe Configuration EM and name the saved data. Oncethe data is saved, the SAVE key disappears until youchange the data in the instrument.

Downloading the saved data requires that you firstmark the configurable variables you wish to download(the default is all variables unmarked). To do this, fromthe Offline menu select Saved Configuration.Depending on the location of the saved data, selecteither Internal Flash Contents or Configuration EMContents. Select the name for the saved data. Fromthe Saved Configuration menu select Edit.

From the Edit menu you can mark all configurablevariables for download, unmark all configurablevariables so none are downloaded, edit each variableindividually, or save your configuration to the internalflash or the optional configuration expansion module.The following briefly describes each item on the menu.For more information, see the User�s Manual for the375 Field Communicator − 00375-0047-001.

variables are those that appear when you editvariables in the configuration using the Edit Individuallyoption.

Unmark All�removes flags from all configurablevariables in the configuration. Unmarked configurablevariables are not sent to a connectedHART-compatible device.

Edit Individually�opens the Edit Individuallymenu to permit editing configurable variables in thesaved data. For information on editing configurablevariables, refer to the Field Communicator productmanual.

Save As...�saves your new configuration to theInternal Flash, or the Configuration EM. For moreinformation on the Save As option, see the FieldCommunicator product manual.

Once the configurable variables are marked fordownload, return to the Saved Configuration menuand select Save. Follow the prompts on the FieldCommunicator to download the saved data to theinstrument.

Polling When several devices are connected in the sameloop, such as for split ranging, each device must beassigned a unique polling address. Use the Pollingoptions to configure the Field Communicator toautomatically search for all or specific connecteddevices.

To enter a polling option, select Utility from the HARTApplication menu. Select Configure HART Application,and then select Polling. Tap ENTER to select thehighlighted option.

The Polling options are:

1. Never Poll�connects to a device at address 0,and if not found will not poll for devices at addresses 1through 15.

2. Ask Before Polling�connects to a device ataddress 0, and if not found asks if you want to poll fordevices at addresses 1 through 15.

3. Always Poll�connects to a device at address 0,and if not found will automatically poll for devices ataddresses 1 through 15.

4. Digital Poll�automatically polls for devices ataddress 0 through 15 and lists devices found by tag.

5. Poll Using Tag�asks for a device HART tag andthen polls for that device.

6. Poll Using Long Tag�allows you to enter thelong tag of the device. (Only supported in HARTUniversal revision 6 devices.)

To find individual device addresses, use the DigitalPoll option to find each connected device in the loopand list them by tag.

For more information on setting the polling address,see the Advanced Setup and Calibration section,Section 4.

MemoryA type of semiconductor used for storingprograms or data. FIELDVUE instruments usethree types of memory: Random Access Memory(RAM), Read Only Memory (ROM), andNon-Volatile Memory (NVM). See also theselistings in this glossary.

MenuA list of programs, commands, or other activitiesthat you select by using the arrow keys tohighlight the item then pressing ENTER, or byentering the numeric value of the menu item.

Minimum Closing TimeMinimum time, in seconds, for the travel todecrease through the entire ranged travel. Thisrate is applied to any travel decrease. Validentries are 0 to 400 seconds. Deactivate byentering a value of 0 seconds.

Minimum Opening TimeMinimum time, in seconds, for the travel toincrease through the entire ranged travel. Thisrate is applied to any travel increase. Because offriction, actual valve travel may not respond inexactly the same time frame. Valid entries are 0to 400 seconds. Deactivate by entering a value of0 seconds.

Non-Volatile Memory (NVM)A type of semiconductor memory that retains itscontents even though power is disconnected.NVM contents can be changed duringconfiguration unlike ROM which can be changedonly at time of instrument manufacture. NVMstores configuration restart data.

ParallelSimultaneous: said of data transmission on two ormore channels at the same time.

Polling AddressAddress of the instrument. If the digital valvecontroller is used in a point-to-point configuration,set the polling address to 0. If it is used in amultidrop configuration, or split range application,set the polling address to a value from 0 to 15.

Pressure SensorA FIELDVUE instrument internal device thatsenses pneumatic pressure. DVC2000 Seriesdigital valve controllers have one actuatorpressure sensor.

Primary MasterMasters are communicating devices. A primarymaster is a communicating device permanentlywired to a field instrument. Typically, aHART-compatible control system or a computerrunning AMS ValveLink Software is the primarymaster.

In contrast, a secondary master is not oftenpermanently wired to a field instrument. TheModel 375 Field Communicator or a computerrunning AMS ValveLink Software communicatingthrough a HART modem could be considered asecondary master.

Note: If one type of master takes an instrumentOut Of Service, the same type must put it InService. For example, if a device set up as aprimary master takes an instrument Out OfService, a device set up as a primary mastermust be used to place the instrument In Service.

Quick OpeningA valve flow characteristic where most of thechange in flow rate takes place for small amountsof stem travel from the closed position. The flowcharacteristic curve is basically linear through thefirst 40 percent of stem travel. One of the inputcharacteristics available for a FIELDVUEInstrument. See also, Equal Percentage andLinear.

Random Access Memory (RAM)A type of semiconductor memory that is normallyused by the microprocessor during normaloperation that permits rapid retrieval and storageof programs and data. See also Read OnlyMemory (ROM) and Non-Volatile Memory (NVM).

RateAmount of change in output proportional to therate of change in input.

Read-Only Memory (ROM)A memory in which information is stored at thetime of instrument manufacture. You canexamine but not change ROM contents.
