1.0 SETPOINT CONTROLLER (SPC) SETUP & CALIBRATION PROCEDURES

1.1 Controller Setup

The Yokogawa, UT-320, controllers used in the plant have three menus of parameters that require settings to be

entered prior to the controller being placed into service. The parameter menus are Setup Input/Output, Setup

Control Functions and Operating Parameters. It is important that the controller be programmed in a specific

sequence for proper operation. Always enter the setup parameters first beginning with Setup Input/Output then

enter the Setup Control Function parameters. When the setup parameters are complete, enter the Operating

parameters. The following tables are provided for each set point controller with the key strokes and values

required for proper controller operation. The tables are arranged in the proper order for parameter setup. It is

recommended that the Yokogawa instruction manual, chapter B2, be used in conjunction with these tables for

controller setup. The “N/A” designation in the table value block indicates that a parameter is not available and it

does not display on the controller.

2.0 CIRCUIT BREAKER CALIBRATION PROCEDURES

2.1 Circuit Breakers

The circuit breakers installed in control panel CP-1 for motor circuit protection are provided with adjustable trip

modules. These breakers include MCP-1, MCP-2 and MCP-5 through MCP-11. The adjustable trip module

enables adjustment of the magnetic trip threshold to a level that allows the motor to start, under load, without

tripping the circuit breaker. This adjustment is made with the red rotary adjuster found in the lower left quadrant

of the breaker face. To adjust the trip setting, use a small screwdriver and gently depress the red adjuster. While

the adjuster is depressed, turn the adjuster to the desired setting and release the pressure from the adjuster. The

adjuster should pop up into the detent for the setting selected. If the adjuster does not return to this position it is

not correctly positioned and the breaker trip setting will not respond properly. When making a trip setting

adjustment never turn rotary adjuster past the minimum or maximum set points. This could cause misalignment

of the mechanism inside the trip module affecting the trip setting. The following table contains the recommended

trip settings for the breakers in CP-1.

2.2 MCP Trip Setting Procedure

With motor off, set MCP trip point as described above low enough to have MCP trip when motor is started. Stop

motor and increase trip point one “notch” at a time until MCP does not trip. Repeat starting and stopping motor

5-10 times to make sure a nuisance trip does not occur. If an occasional trip occurs, set MCP adjustment up one

notch.

MCP-10 15AMP F 120AMP MCP-11 15AMP F 120AMP

2.3 Resetting Circuit Breakers

If a circuit breaker senses an out of range current that is greater than its trip rating, the breaker will “trip” to the

mid-position (the middle between Open and Closed) and disconnect the circuit thus stopping current from flowing

before the circuit and/or connected devices are damaged. Once the circuit breaker “trips”, it will remain in the

tripped condition preventing the circuit from energizing until the circuit breaker is “reset” by first pushing the

breaker to Open and then back to Closed.

However, caution must be used before resetting the breaker. Before resetting circuit breakers and especially those

that trip at a high current rating, use the high voltage range (500 volts or more) on a multi-meter for 480vac

circuits and a lower range for 240/ 120vac circuits (250 volts) and ensure that power has been disconnected from

each circuit conductor by reading the potential difference between each conductor and between each conductor

and ground.

If all voltage has been removed from all conductors, first select a resistance range of 100 ohms on the meter.

Next read the resistance between all conductors connected to the circuit breaker. If a reading of 0 ohms is

obtained for any reading, disconnect loads from the circuit breaker to isolate the load reading 0 ohms. Inspect this

device visually and by smelling for burned electrical insulation. Ensure no electrical faults have occurred to

damage the component before returning it to service. If other loads connected to the same circuit breaker read 10

ohms or less, inspect each component and ensure no electrical damage has occurred.

of 129



Next read from each of the connected circuit conductors to a ground connection using a high resistance scale of 1

meg ohm or more. If the reading is 50,000 ohms or less, the insulation on the conductor or one of the connected

components is likely damaged and must be disconnected from the circuit before the breaker can be reset and

closed.

Some circuit breakers may have to cool for a short period of time before they can be reset. If when attempting to

push the breaker handle to the Open position the handle will not stay in the Open position, allow the breaker from

5 to 10 minutes to cool before attempting to reset it once again. The 2nd attempt should be successful.

3.0 MOTOR SOLID STATE OVERLOAD RELAY

The motor starters installed in control panel CP-1 are provided with solid state overload relays. These solid state

relays work by sensing the current in the wire feeding the motor as it passes through the sensing window of the

relay. When the motor current reaches an overload condition the relay opens a set of contacts which causes the

motor starter to drop out stopping the motor. The tripped condition of the relay must be manually reset before the

motor can be restarted. The trip setting of the relay is adjustable by the trip adjustment located on the left side of

the relay face. The relays have different adjustable ranges based on the size of the motor connected to the starter.

Some of the overload relays have the conductor feeding the motor passing through the relay sensing window more

than once. This is done because the lowest adjustable range of the relay trip setting is 3-6 amps and the motor full

load amp (FLA) is lower than the lowest trip setting. The following table lists the motor FLA, trip range, trip

setting and number of times the motor conductor passes through the sensing window.

3.1 RESETTING MOTOR SOLID STATE OVERLOAD RELAYS

After an overload “trips”, it will remain in the tripped condition preventing the motor from starting until the

overload unit is “reset” by pushing the reset button mounted in the face of each motor starter enclosure within CP-

1. A tripped condition will be noticed when depressing the reset button in that when pushing on the button, some

resistance will be noticed. On a unit that has not tripped, no resistance will be noticed when the button is

depressed.

After an overload unit has tripped due to a motor overload condition and before depressing the reset button, the

motor needs to be checked to ensure that it hasn’t been damaged. Using the Digester Blower motor DB-01 (line

58) as an example, after opening the supply circuit breaker MCP-5 use the high voltage range (500 volts or more)

on a multi-meter and ensure that power has been disconnected from each motor supply conductor by reading the

potential difference between each conductor (5M1, 5M2 and 5M3) and between each conductor and ground.

After ensuring no power is present on the supply conductors, use the lowest scale resistance setting on the meter

and measure the resistance of each motor lead at terminals 5T1, 5T2 and 5T3 measuring from 5T1 to 5T2, from

5T1 to 5T3 and last from 5T2 to 5T3. The amount of resistance will vary from approx. 10 ohms or somewhat

higher for small motors to 5 ohms or less for larger motors. If any resistance reading is 0 ohms, the motor is most

likely shorted and will have to be replaced. If any resistance reading is extremely high the motor has an open wire

that will have to be repaired. Also read from each of the motor leads to a ground connection using a high

of 129



resistance scale of 1 meg ohm or more. If the reading is 50,000 ohms or less, the insulation on the motor

windings are most likely damaged and the motor will have to be replaced.

After taking the readings as described directly above, visually inspect the motor if possible. If the motor is

extremely hot and especially if a noxious burnt smell is observed the motor is most likely damaged and must be

replaced.

If the motor passes all inspections and readings, ensure that the multi-meter is removed from any connection to

the power circuit and re-energize the circuit by closing circuit breaker MCP-5.

Before resetting motor starter overload relay, connect the fluke current probe on the motor leads one at

a time and measure motor running current in each phase after reset button on overload is reset or MCP

is reset. Compare this to the full load amps listed in the O&M spreadsheet under MOTOR DATA

SHEETS. Do Not reset motor overload relay until current measurements are made. On the face of the

motor starter, depress the reset button and if tripped, a small click will be felt in the button and also possibly

heard. This click will indicate that the overload device was tripped and has been reset. It is possible that if the

overload device has just tripped, depressing the reset button will not reset the device as not enough time has

elapsed to cause the device to cool and reset. If this condition is observed, wait a short period of time (5 to 10

minutes) and depress the reset button once again. The 2nd attempt should reset the overload device.

After the overload device is reset, the motor starter will once again energize and run the motor if the motor is

required to run by the control circuit connected to it.

4.0 VARIABLE FREQUENCY DRIVE SETUP

WARNING: The Roots Blowers, VFD drive controller, Motor system for the blowers B01 & B02 are an

integrated system which must be run within the following parameters:

1. Minimum Roots 36-U-RAI blower speed 1200 RPM for proper blower cooling, 21Hz on VFD. Blower output at 1200 RPM = 70 SCFM Operating pressure is approx. 4.7 PSI.

2. Maximum Roots 36-U-RAI blower speed 2761RPM , 47Hz on VFD. This is the limit to prevent motor overload. Blower output at 2761 RPM = 225 CFM. Operating pressure is approx 4.8 PSI.

3. In manual control of speed from setpoint controllers SPC-3 & 4 the output of 0-100% corresponds to blower speed of 25Hz = 1460RPM at 0%, and at 100% output blower speed is 2761 RPM. System pressure remains fairly constant at about 4.7 psi as the height

The ABB variable frequency drives (VFD) used in the plant provide speed control and all motor protection for the

aeration basin blowers. These drives have an extensive group of parameters that require programming for proper

drive operation and motor/equipment protection. The drive parameters are divided into the following five main

venues:

1. Start-up Data

2. Operating Data

3. 10 Control Connections

4. 20 Drive Parameters

5. 30 Protection/Information

All drive parameters are accessible through the keypad and display screen located on the front of the VFD. The

ABB publication “Programming Manual Including Application Macros” should be used in conjunction with these

setup instructions to insure proper drive operation. Some of the VFD parameters are for information display only

and do not have selectable values. These will be identified by N/S in the value block of the parameter tables. The

drive contains parameters that are not displayed in the custom setup for this application and these parameters are

omitted in the following instructions and value tables.

Step 1) To calibrate the totalizer, the first step is to determine the correct adjustment that will give the desired 1 pulse per minute to represent the maximum flow of 100 GPM as per the above chart. A 12 position DIP switch is located internal to the integrator with the no.8 switch providing a maximum flow of 1 pulse per 100 gallons. To provide the required output, the no.8 switch will be turned on and all other switches off.

However, only for the purpose of speeding up the process of calibration, the no. 5 switch should be used which will give a pulse rate of 64 pulses per minute instead of the much slower 1 pulse per minute provided by switch no.8. To calibrate the integrator, open all switches except the no. 5 switch which should be on. After the calibration has been completed, the no. 5 switch will be turned off and the no.8 switch will be turned and left on.

Step 2) The next step is to attach a current source test meter to simulate the flow meter (FM-1) output. At line 642 of schematic drawing EC4, disconnect FM-1 from the circuit by removing the jumper from TP20 and TP21. Next connect the test meter in source mode (simulates a 4-wire transmitter) to TP19 and TP20. With the meter’s positive lead connected to TP20 and its negative lead connected to TP19, generate a 20ma signal.

Step 3) After a 20ma signal is generated, observe the count of the Flow Totalizer Counter (OC13, line 644). Adjust the SPAN control (located on the top of the integrator) so that OC13 reads at the rate of 1 count per minute (or 4 counts per 30 seconds or 2 counts per 15 seconds).

of 129



Step 4) When the 8 counts per minute is achieved, next reduce the output of the current source meter to 10% of maximum or 5.6 ma. Adjust the ZERO setting (also located on the top of the integrator) to 10% of the maximum output or 1 count per 75 seconds.

Step 5) Repeat steps 3 and 4 above at least one more time or more as changing the setting of one of the adjustments effects the setting of the other, e.g., moving the ZERO setting will effect the SPAN setting which will then need to be readjusted. After performing steps 3 and 4 a few times, the adjustments become so small that additional adjustments are not necessary.

Step 6) After the output has been calibrated, disconnect the test meter, open switch no. 5 and close switch no.8 (as in step 1 above) in the integrator and reconnect the circuit jumper to TP20 and TP21. The integrator should now be calibrated and back into service.

7.3 INFLUENT FLOW RECORDER

The influent flow recorder, Rustrak model #288, provides a continuous strip chart record of influent flow into the

plant. The recorder is factory set for 0 – 100 GPM (4ma = 0 gpm, 20ma = 100 gpm) with the required

calibrations as described below.

7.3.1 Influent Flow Recorder Calibration

Calibration of the chart recorder consists of two steps, Zero On Scale and Zero Off Scale as described below. The

zero adjustment is located behind the front nameplate of the recorder which can be removed by inserting a small

flat screwdriver into the left hand slot and prying the nameplate off. Adjust according to the following procedures

and when finished, replace the nameplate by snapping it back into place.

Step 1) To calibrate the Zero On Scale, disconnect the 4-20ma signal from flow meter FM-1 by unplugging the jumper from TP20 and TP21 (schematic drawing EC4, line 642).

Step 2) Next, rotate the zero adjustment to give recording on the zero point on the chart in the recorder. To check accuracy, attach the current source test meter to simulate the flow meter (FM-1) output. At line 642 of schematic drawing EC4, connect the test meter in source mode (simulates a 4-wire transmitter) to TP19 and TP20.

Step 3) With the meter’s positive lead connected to TP20 and its negative lead connected to TP19, generate a 4-20ma current signal. Increase the output of the current source meter to 12ma and then again to 20ma and notice where the pen resides on the chart at these points. At 12ma the pen should read 50

of 129



gpm and at 20ma the reading should be 100 gpm. The maximum error should be less than ±2% of span.

Step 4) To calibrate for Zero Off Scale, with the current source meter still connected in the circuit at TP19/ TP20, set the current source meter at 12 ma and adjust the mechanical adjustment to give recording on the 50% line of the chart paper. (Note: recorder can only be calibrated at one point.) Use 50 GPM (12 ma) to calibrate recorder as total flow will be between 30 – 50 GPM in all cases.

Step 5) Once again, check the accuracy by increasing the output of the current source meter to 12ma and then again to 20ma and notice where the pen resides on the chart at these points. At 12ma the pen should read 50 gpm and at 20ma the reading should be 100 gpm. The maximum error should be less than ±2% of full scale value.

Step 6) After calibration procedures are completed, return the circuit to normal use by disconnecting the current source meter and reconnecting the circuit jumper to TP20 and TP21.

Note: Should the recorder require factory repairs if calibration is not successful, the flow circuit can be use while the recorder is removed. To use the flow circuit without the chart recorder, turn the Run/ Bypass switch (SS4, line 647) to bypass. The recorder can then be removed for repairs while the flow circuit remains in use.

7.4 WATER TANK LEVEL TRANSMITTER (LT-3) and INDICATOR (DD-1)

7.4.1 Water Tank Level Transmitter

The accuracy of this transmitter can be checked by adding markings at exactly 1 foot intervals along the length of

the transmitter cable and lowering the instrument into water and measuring current values at each marking.

Follow the procedure as given below to calibrate LT-3.

Step 1) To calibrate the LT-3 transmitter, disconnect the transmitter from its circuit by disconnecting the positive field wire (+1) connected to the transmitter (schematic drawing ANE3, line 4288). This connection will be in a terminal box at the transmitter field location. Connect the positive field wire (+1) to a current test meter that reads in a milliampere (ma) scale. Connect the disconnected transmitter wire to the other meter lead. If the test meter does not read in a positive direction, reverse the connection or reverse the leads on the meter so that a positive reading is observed.

Step 2) Next use a 2 inch diameter, 24 foot long PVC pipe with a pipe cap on one end and fill the capped pipe with water or just use water in water tank when as full as possible close to overflow level. Pull the level transmitter from the Water Tank and mark one foot intervals on the transmitter cable by

of 129



wrapping with white electrical tape. Start the first wrap one foot from the end of the transmitter and wrap 23 more level designations for a total of 24 feet.

Step 3) After the tape markings have been added, lower the transmitter into the water filled calibration tube or in water tank. Starting at 0 feet and at each one foot level, observe the test meter readings and compare these values with the values listed on the following chart. If any of the 23 readings obtained vary more than 0.1% of full scale output (approx. 1/4 inch), replace the transmitter with a new unit.

Step 4) After calibration is complete and the unit has been verified to be operating correctly or has been replaced with a new unit, lower the transmitter in the water, disconnect the test meter and reconnect LT-3 to the positive wire (+1) to return the transmitter to service.

Note: To aid in the understanding of the values given in the chart below, note that each 1 psi of pressure represents 2.31 feet of liquid elevation and therefore, 10 psi will equal 23.1 feet of liquid.

Also notice that the chart gives identical information in two different forms. The three columns on the left of the double line divider show psi and ma in relation to increasing elevation starting at 0 feet. The three columns to the right of the double line show psi and feet in relation to increasing increments of current in ma also starting at 0 feet.

7.4.2 Water Tank Level Indicator

The Water Tank Level indicator located in the Remote Light Box (drawing ANE3, line 4285) requires calibration

as per the following procedure. Dip switches must be set as follows before calibration can start if a new unit is

installed Insert DIP switch settings shown in cut sheet 16900-2.45 for loop powered indicator for zero span and

decimal points.

Step 1) To calibrate the indicator, disconnect both indicator wires from the terminal blocks in the Remote Light Box and connect to the Rochester Signal Generator with the positive (red) wire from the generator connected to wire 4279F and the negative (black) wire from the generator to wire number 4279G. Set the signal generator to source mode and generate a 4ma signal.

Step 2) With the Display switch in the Engineering Units position, set the Zero setting adjust on the indicator to read 0ft. Increase the output of the generator to 20ma and adjust the Span setting to read 23.1ft.

Step 3) Because the Zero and Span settings are interactive, return the generated signal to 4ma and readjust the Zero setting to 0ft. Return the generated output to 20ma and adjust the Span setting for 23.1ft. Repeat this procedure until no noticeable shift occurs on either the Zero or Span settings after the other setting is adjusted.

Step 4) After Zero and Span settings are stable, return the generator to a 4ma setting and slowly increase the output and notice the display readings according to the above chart for calibrating the Water Tank Level transmitter (LT-3). The readings should correspond, e.g., at 8ma the display should read 5.775 feet, at 12ma the display should read 11.55ft, at 16ma the display should read 17.325 feet, etc. The other milliamp values should also correspond in like manner. If any reading varies by more than ±0.1% (appprox. 1/4in.), replace the display with a new unit.

Step 5) After calibration is complete, disconnect the display from the test generator and reconnect to the instrument loop by connecting wire 4279F to terminal TSG1-27L and wire 4279G to terminal TSG1-27U.

7.5 INFLUENT/EFFLUENT SAMPLERS

When testing the loop by activating the sampler, the count number could stay at “ 5 “, and a 20.0 mA input signal

could be applied. The sampler would then sample every five (5) minutes during the test period.

Programming the sampler for flow pacing involves entering a new program, and where it requests the user to

select “time” or “flow” pacing, select “flow” and make the count number “ 5 “.

Regardless of plant operation and pumped flows, the sampler will sample only when a specific volume has passed

through the flow meter, in this case every 500 gallons.

7.5.1 4-20 mA Input for Flow Proportional Sampling

An optional interface unit is available (P.N. 2021) which converts a 4-20 mA flow meter output into 12 VDC

pulses. At 20 mA (100% flow rate), the interface sends ten pulses per minute; at 4 mA (0% flow rate), the

interface sends zero pulses.

The interface has a 1.5 ft. cable with a connector on one end, and a 10 ft. cable with two open wire leads on the

other. After all field wiring has been connected and completely tested, insert the connector into the sampler

receptacle labeled AUXILIARY, located on the left side of the control housing. With respect to the 10 ft. cable,

the wire with clear insulation is POSITIVE (+) and the wire with black insulation is NEGATIVE (-).

Note: Part # 2021 interface works with either wire connected to positive (+) input wire.

Older model 4-20 mA interface (#2020) requires current loop polarity to work properly.

7.5.2 Required Calculations

1. Calculate “Q”. “Q” is Average Flow Rate / Maximum Flow Rate (20 mA. value).

2. Calculate “t”. “t” = a/n. “a” = time in minutes for sampling program “n” = number of desired samples

3. Multiply “Q’ by “t”. Resulting product is number of counts to be entered into program. This number must be a whole number, such as 10, 13 or 20.

These calculations may have to be completed a number of times to compensate for seasonal variations in flow, or to accommodate specific plant operating conditions.

Further technical assistance regarding external device control and flow-paced sampling is available via American Sigma’s toll-free number – (800) 635-1230.

Influent and Effluent Samplers provide a method of automatically removing samples for analysis from influent/

effluent flows to/ from the treatment plant. The samplers are connected to the flow loop of FM-1 (drawing EC4,

line 638) through the I/I (current to current) repeater shown at line 643. The 4-20ma flow signal connected to the

samplers (line 756) from the I/I repeater is analyzed by the samplers and integrated to provide a signal for

energizing various electrical valves that remove samples from the system. The samplers require calibration as

described below:

of 129



7.5.4 Influent/ Effluent Flow Sampler Calibration

Step 1) Note: before calibrating sampler loops and setting sampler controller count number as calculated above, calibrate I/I, 4-20ma repeater first. See instructions for this calibration at end of this section: CURRENT T0 CURRENT (I/I) TRANSDUCER.

Remove the installed jumper from TP20 and TP21. Connect the Rochester current source generator and set to the source mode of operation. Connect the positive lead of the generator to TP20and the negative lead to TP19.

Step 2) Generate different levels of current that correspond to various levels of flow as per the following list. Observe that the samplers operate at the levels as indicated. See sampler calibration procedures above for count number calculations.

4ma = 0% or no flow.

8ma = 25%, or 25gpm.

12ma = 50% or 50gpm.

16ma = 75% or 75gpm.

20ma = 100% or 100gpm.

Step 3) If the output of either sampler varies by more than 3% of any value, the sampler will require recalibration as per the manufacturer’s recommendations.

Step 4) Disconnect the current generator from the circuit and reinstall the jumper to TP20 and TP21 to return the circuit to service.

7.6 PHASE MONITOR RELAY

The plant power system is monitored by two phase (power) monitor relays. The PMR1 relay, time mark MDS

#C2652, monitors the 480 volt power and PMR2 relay, time mark MDS # B2652 monitors the 208 volt system.

Both relays are set up and calibrated in exactly the same manner using the three adjustments pots on the face of

the relay housing.

Step 1) Adjust the reset delay pot to the minimum setting.

Step 2) Adjust the trip delay pot to the maximum setting.

Step 3) Turn the voltage adjust pot clockwise until the unit trips (normal indicator OFF; trip indicator ON).

Step 4) Slowly turn the voltage adjust pot counter-clockwise until the unit resets (trip indicator OFF; normal indicator ON).

Step 5) Adjust the reset delay pot to the maximum setting.

7.7 SEPTIC TANK LEVEL TRANSDUCERS (LT-1 & LIT-2)

The provided level transmitters for the STEP-01 and STEP-02 vaults measure pressure of the liquid they are

immersed in to produce a 4-20ma current that represents the level of the liquid.

7.71 Septic Tank Level Transmitter LT-1 & LT-2 Calibration

The accuracy of these transmitters can be checked by adding markings at exactly 1 foot intervals along the length

of the transmitter cable and lowering the instrument into water and measuring current values at each marking.

Follow the procedure as given below to calibrate LT-1. The calibration for LT-2 is identical.

Note calibration is only done in one foot increments from 0 – 10 feet of water as level in STEP vault will never be

higher than 8.0 feet if Septic tank flooded. Span adjustment is set at 0 feet and at 10 feet to get greater accuracy

rather than at 23.1 feet.

Step 1) To calibrate the LT-1 transmitter, disconnect the transmitter from its circuit by disconnecting the positive field wire (+3) connected to the transmitter (schematic drawing EC3, line 477). This connection will be in a terminal box at the transmitter field location. Connect the positive field wire (+3) to a current test meter that reads in a milliampere (ma) scale. Connect the disconnected transmitter wire to the other meter lead. If the test meter does not read in a positive direction, reverse the connection or reverse the leads on the meter so that a positive reading is observed.

of 129



Step 2) Next use a 2 inch diameter, 10 foot long PVC pipe with a pipe cap on one end and fill the capped pipe with water. Pull the level transmitter from the STEP vault and mark one foot intervals on the transmitter cable by wrapping with white electrical tape. Start the first wrap one foot from the end of the transmitter and wrap 10 more level designations for a total of 10 feet.

Step 3) Adjust the zero setting (located in the STEP vault in a clear plastic J box) by turning the zero potentiometer until the meter reads 4ma.. Next lower the transmitter into the capped test tube until the 10 foot level is reached and adjust the span setting (located in the same J box) to 10.962ma at 10 feet of water depth.

Step 4) Repeat step 3 above several times until both zero and span adjustments are stable (both do not vary when adjustments are made for 4 or 20ma).

Step 5) Pull the transmitter from the water, reinsert starting at 0 feet and lower the transmitter into the water filled calibration tube. Starting at 0 feet and at each one foot level, observe the test meter readings and compare these values with the values listed on the following chart. If any of the 10 readings obtained vary more than .1% of full scale output (approx. 1/4 inch), replace the transmitter with a new unit.

Note: To aid in the understanding of the values given in the chart below, note that each 1 psi of pressure represents 2.31 feet of liquid elevation and therefore, 10 psi will equal 23.1 feet of liquid.

Also notice that the chart gives identical information in two different forms. The three columns on the left of the double line divider show psi and ma in relation to increasing elevation starting at 0 feet. The three columns to the right of the double line show psi and feet in relation to increasing increments of current in ma also starting at 0 feet.

7.8 BLOWER PRESSURE TRANSDUCERS (PT-1, PT-2, PT-3, PT-4)

The setup and calibration procedures for the blower pressure transducers (PT-1, PT-2, PT-3 and PT-4) are exactly

the same. Yokogawa model # EJA430A pressure transmitters, with a calibrated range of 0-15 PSI, are used in the

plant for blower output pressure monitoring. These transmitters are provided with digital communication

capabilities using the Yokogawa BRAIN protocol. A thorough understanding of the use of the Yokogawa BT200

Brain Terminal is required to accomplish the setup and calibration of the transmitters.

7.8.1 Pressure Transmitter Setup

Operation of the Brain terminal is described in chapter 8 of the Yokogawa Instruction Manual found in the

Multnomah Falls Operation and Maintenance Instruction manual, section 16900 2.54. The operator needs to be

thoroughly familiar with this chapter before using the Brain Terminal. As an aid to the instruction manual, the

below narrative gives concise instruction for the setup values required to operate the 4 transmitters found on the

Multnomah Falls WWTP site. The narrative is written specifically for PT-1 (Aeration Blower B-01) but is

identical for the other three transmitters (PT-2, PT-3 and PT-4) except for the line references found in the

schematic drawing. Following the narrative, a chart is given that summarizes the parameters required for the on

site transmitters.

7.83 Pressure Transmitter Calibration

To maintain the +/-0.2% accuracy of the Yokogawa transmitter a full pressure range calibration should be done if

any zero shift is indicated during normal plant operation. To check transmitter for zero shift close the impulse

line block valve and vent pressure capsule to atmosphere. With a digital multimeter of known accuracy connected

in series in the analog output loop (reference step no.2 below), measure the ma current. The reading should be

4.00ma. If the error is +/-0.2% (+/-0.024ma) or greater, a full range calibration is necessary.

The following narrative refers to calibration for the Aeration Blower Pressure Transmitter, PT-1. Other pressure

transmitters (PT-2, PT-3 and PT-4) will use the same method and steps for calibration.

Step 1) Connect the Brain Terminal unit to the flow loop circuit conductors at terminal strip TS9-7 and TS9-8 (schematic drawing EC4, line 550). Connect the red connector to the positive wire or TS9-7 and the black connector to the negative wire or TS9-8. Turn the unit on by pressing the Power On/Off key. Reference the section Brain Terminal Condensed Instructions in the pressures transmitter calibration narrative above for additional Brain terminal instructions.

Step 2) Set the “HIGH RANGE” parameter to 15 PSI (C22:High Range, step 4D in the above pressure transmitter calibration procedures). Set the external zero adjustment parameter to “ENABLE” (J20:Ext.Zero Adjust, accessed from the ADJ (F3) key at the Brain terminal Home Menu Panel).

Step 3) Connect a digital multimeter of known accuracy in series in the analog output loop. This is accomplished by removing the installed circuit jumper from test points TP8 and TP9 (schematic drawing ED4, line 550) and connecting the positive multimeter lead to the TP9 connection and the negative lead to the TP8 connection. Set the meter to a scale that reads as close to 0 to 20ma as possible.

Step 4) Connect an air compressor, a pressure regulator (to modulate the pressure 0 to 15 psi from the air compressor) and Fluke pressure sensor to the high port on the transmitter. Apply reference pressures of 0 PSI, 7.5 PSI and 15 PSI. As pressures are increased note the ma signals.

0 PSI = 4.00ma = 0%

7.5 PSI = 12.00ma = 50%

15 PSI = 20.00ma = 100%

Note pressure readings both upscale and down scale. If error is +/-0.2% perform Step 4.

of 129



Step 5) With pressure at zero adjust, zero adjustment screw until ma reading is 4.00ma. Increase pressure to 15 PSI. Adjust zero adjustment screw, if necessary, until ma reading is 20.00ma. Repeat this step until 0PSI = 4.00ma and 15 PSI = 20.00ma without adjustment of the zero adjustment screw.

Step 6) Perform a 9 point calibration check with a digital multimeter connected to the circuit (as described in step no.3 above) and calculate the average error using the following chart.

PRESSURE CORRECT ma OUTPUT

ACTUAL ma OUTPUT

% ERROR

0 PSI 4.00 ma 3.75 PSI 8.00 ma 7.50 PSI 12.00 ma

11.25 PSI 16.00 ma 15.00 PSI 20.00 ma 11.25 PSI 16.00 ma 7.50 PSI 12.00 ma 3.75 PSI 8.00 ma

0 PSI 4.00 ma AVERAGE

ERROR

((Actual ma – Correct ma) ÷ 12) x 100 = % Error

If the average error is not less than 0.2%, the transmitter should be returned to Yokogawa for repair.

Step 7) Reset the “HIGH RANGE” parameter to 15PSI and the external zero adjustment parameter (J20) to “INHIBIT”. Return the transmitter to service by disconnecting the test current meter, test pressure meter and reconnecting the jumper to TP8 and TP9.

7.9 TEMPERATURE TRANSDUCERS

The setup and calibration procedures for the plant temperature transducers (TT-1, TT-2 and TT-3) are exactly the

same. Accutech model AT-1000 R2 temperature transmitters, with a calibrated range of 0 – 120 deg F are used to

monitor lab Room, Equipment Room and outside air temperatures. These transmitters are fully programmable

through the integral DK-2 display module. The Accutech “Operating Information” manual for model AI-1000 R2

is required for transmitter configuration and calibration procedures.

of 129



7.9.1 Configuration Parameters

The Accutech Operating Information manual (found in the Multnomah Falls Operation and Maintenance Manual,

16900, sec 2.42 Vol.1) Chapter 4.0 pages 11 through 22 lists the steps required to configure the temperature

transmitter to the correct values as listed in the chart at the end of this section. Also refer to the Configuration

Flowchart given on page 43 of the Operating Information manual.

The method used to select and enter data is to use the Next and Enter keys located on the face of the transmitter

LCD display. The programming procedure is menu driven and by answering the preprogrammed question in the

displayed LCD menu, all parameters can be programmed. Using the Next key in effect enters a no answer and

brings up the next event in the menu. Similarly, pushing the Enter key answers yes to the value or question

shown on the display and also advances the menu to the next step. Notice that when pushing the Next and Enter

buttons, each button must be held for a short period of time to avoid entering a wrong value. The following is a

step by step summary of the required procedures.

Step 1) From the Operate Mode (the mode displayed while the transmitter is in operation), push the Next key. The display will read “Return to Operate Mode?”

Step 2) Push the Next key and the display will read “Select Input?” After pushing Enter, the display will start displaying a series of temperature thermocouple sensors options that can be connected to the transmitter. The operator must scroll through each option until the presently connected thermocouple is displayed. For each option that is displayed, push Next until the 3W DINP option is displayed. This will be the 15th sensor displayed option. When 3W DINP is displayed, push Enter because this is the type of the installed sensor (refer to the temperature transmitter chart).

Step 3) After pushing Enter, the next display will read “Select Units?” If a change of units is required, push Enter and “DEG F” will be displayed. Because this is the required Unit as per the chart, pushing Enter will establish degrees F as the working unit and cause the display to bring up the next parameter. Pushing next at this point will cause the display to scroll through all of the optional units as was true of the sensor types in step 2 above.

Step 4) After pushing Enter from step 3 above, the display will then alternate between “Change” and “Zero” in addition to showing the presently entered zero (4ma) value. If the zero point is not required to be changed, enter Next and the display will go to the next function. If the zero value need to change, push the Enter key and the display will then read “Plus?” This is asking if the required value is 0 or

of 129



greater and if so, push Enter. If not, pushing Next will display “Minus?” If the temperature reading is to be less than 0 for the 4ma value, push Enter.

Step 5) After selecting the correct plus or minus function, the display will read “THOUSN?” This is referring to the value of the 4th digit in the display. If the 4ma reading is less than 1,000, push Enter and the default 0 will be entered into the transmitter’s memory. If the 4ma value is 1,000 or greater, pushing next will bring up the number 2 in the 4th digit display and pushing Next will scroll to the number 3, etc. Pushing Enter at the correct value for the 4th digit will enter that digit and move the menu to the 3rd digit in the 4ma value display.

Step 6) After the correct 4th digit is selected, the display reads “HUNDRED?” Using the same procedure as in step 5 above, scroll through all digits using the Next key until the correct value shows and is entered.

Step 7) This process is repeated until all digits are entered for the zero or 4ma output value of the transmitter. For the current value as per the chart at the end of this section, all digits for the zero value will be 0.

Step 8) After the last digit is entered (tenths), the display will continuously scroll three displays from “CHANGE” to “FULL” to “SCALE?” In addition, each display will show the current full scale value (the 20ma value) in a way similar to the zero value menu displays. To change the full scale value, push Enter. To scroll the menu to the next function push Next.

Step 9) If the full scale value is required to be changed, pushing Enter will cause the display to scroll though menus identical to that of the zero value starting at step 4 above. The current full scale value is 120 degrees F as per the chart. Enter full scale values as required as per the zero value procedure above.

Step 10) After the full scale value has been set (Enter was pushed), the display will then continuously scroll four displays from “SELECT” to “SENSOR” to “FAIL” to “SAFE?” Pushing Enter will display “ON” and pushing Next from “ON” will display “OFF”. Pushing Enter On or Off will choose that function and the menu will scroll to the next function. Enter a fail safe function of On as per the chart.

Step 11) After the fail safe mode has been set (Enter was pushed), the display will then continuously scroll four displays from “SELECT” to “FAIL” to “SAFE” to “REPORT?” Pushing Enter will bring up the menu “HIGH?” Choosing Next will bring up “OFF” and choosing Next again will bring up “LOW” Choosing one of these functions by pressing Enter puts that function into the transmitter memory and scrolls to the next function. The current fail safe report is High.

Step 12) The last four functions should never be required to be changed. Therefore, enter Next for these functions to enter the presently used parameters as per the temperature transmitter chart. If modification is required, reference page 19, section 4.9 through page 21 of the Accutech Operating Information Manual.

7.9.2 Transmitter Calibration

The Accutech AI-2000 R2 temperature transmitter contains an on-board reference standard that the transmitter

uses to run a self-calibration once every 3 seconds. This eliminates the requirement for field calibration. The AI-

2000 does provide a trimming function that allows some adjustment of the 4-20 ma signal. This procedure is

found on page 19 of the Operating Information Manual and should be performed only as a last resort as it voids

the NIST traceability of calibration.

7.10 INFLUENT FLOW METER (FM-1)

The influent flow into the plant is monitored by the Yokogawa Admag AE magnetic flow meter located in the

equipment room. The remote mounted flow meter model AE205D, and the flow converter, model AE14 make up

the complete device for this application. The flow meter generates a voltage signal directly proportional to the

velocity of the fluid moving through the flow meter tube. This voltage signal is then converted to a standard 4-

20ma analog signal by the flow converter.

of 129



7.10.1 Influent Flow Meter Setup

The flow converter has display, function and data parameters that require setting before the flow meter is placed

into operation. The parameters are accessible by using the SET, SHIFT and INC keys located directly below the

display on the flow converter or by connecting the Yokogawa BT200 Brain Terminal to the two pins provided,

below the keys on the display. The instruction manuals for the flow converter and the flow meter contain step-by-

step instructions for accessing each parameter through the display keys and the BT200 terminal. Refer to these

instructions and set each parameter to the value shown in the following table. Also refer to the condensed

instructions for Brain Terminal usage as described below.

7.10.2 Brain Terminal Condensed Instructions

Step 1) Connect the Brain Terminal unit to the flow loop circuit conductors at terminal strip TS9-37 and TS9-38 (schematic drawing EC4, line 642). Connect the red connector to the positive wire or TS9-38 and the black connector to the negative wire or TS9-37. Turn the unit on by pressing the Power key.

Step 2) The screen displays “Please Wait” for a few seconds. After the unit initializes, the startup screen displays “Welcome” at the top of the screen. Press the Enter key and the Home Menu Panel will be displayed.

Step 3) From this screen, all the values found in the FM-1 Flow Meter Setup chart at the end of this section can be accessed. For example, to access the F01 Pulse Select parameter, use the Down Arrow key and scroll the cursor down to menu F.

Step 4) Push the Enter key once again and the F:Pulse Set menu opening screen is displayed. From here the entire F menu items in the FM-1 Flow Meter Setup chart can be selected. Because all items in one particular menu cannot be shown on one screen, to view addition screens in the same menu press the Right Arrow key until the correct screen is reached. To go back to previous screens, press the Left Arrow key . To move the cursor to the desired parameter on individual screens push either the Up Arrow or Down Arrow keys. To go back to the Home Menu Panel, press the Home key or the ESC key until the Home Menu Panel appears on the screen.

To select letters, first use the Shift keys at the bottom of the terminal then select the letter. For example, to select the letter A, first use the left Shift key (L-Shift) which has a filled in square in the upper left corner of the key which corresponds to the same position of the letter A on the key on which it is placed. Then press the key with the letter A. To enter the letter R, first press the Shift key (R-Shift) in the lower right corner as it has a square in the upper right of the key that corresponds to the place that R is found on its key. Then press the R key.

of 129



Step 5) Because entering each item on the chart below requires some knowledge of the parameter being entered and because different parameters have different requirements for data entry, it is highly recommended that the operator review the Admag AE100M Instruction Manual found in the Multnomah Falls Operation and Maintenance Manual section 16900 2.57 to aid in correctly entering data into flow meter memory. Starting at page 7-1 and in particular page 7-6 and following, the correct data entry procedures are listed for many parameters. In addition, reference the Parameter Summary starting on page 12-1 of the same manual.

For a concise data entry procedure, follow the instructions as listed below and enter the values as found on the FM-1 Flow Meter Setup chart at the end of this section. The steps below follow the same sequence of parameters as that listed in the chart.

7.10.3 Influent Flow Meter Calibration

7.10.3.1 Zero Adjust

The Yokogawa AE200D flow meter cannot be field calibrated although a “zero adjustment” can be made through

the AE14 flow converter or by using the BT200 terminal. The procedure for zero adjustment is explained in

detail in chapter 7 and also in chapter 8 of the AE14 instruction manual. If a “zero adjustment” does not correct a

of 129



zero error, return the unit to Yokogawa. A shortened version of the auto zero adjustment is given below. Note

that a manual zero adjust procedure was previously given in the Influent Flow Meter Setup section of this manual

in step 5T – C02, Magflow Zero. Before performing the below procedure, the operator must become familiar

with the Brain terminal functions as listed in the Influent Flow Meter Setup section.

Step 1) From the Home Menu Panel, scroll with the Down Arrow key to parameter C:Adjust, push Enter and the cursor will be on C01.

Step 2) Scroll with the Down Arrow key to C02 and push Enter.

Step 3) Wait a few seconds and push Enter again. AUTOZERO will now be displayed.

Step 4) Wait 30 seconds while the auto zero function is calibrating the correct value and push the F4 key, OK to enter the automatically calibrated value.

Step 5) After OK was entered, the screen will display the C02 menu along with the zero correction value that was automatically calibrated. Then the meter returns to the Data Display Mode.

17.10.3.2 Loop Test

The last feature of the AE14 flow converter is the “Loop Test” function. This allows the AE14 to be used as a

signal generator to test the function of the 4-20ma output loop. The entire procedure is explained in Chapter 9 of

the AE14 instruction manual. A shortened version of the loop test is given below:

Step 1) From the Home Menu Panel, push the Right Arrow key one time and the parameter G:4-20 SEL will be highlighted.

Step 2) Scroll with the Down Arrow key to H:Test. Push Enter.

Step 3) Parameter H01 will be highlighted. Push Enter.

Step 4) Highlight TEST and push Enter twice.

Step 5) Push the Left Arrow key and the display will go back to the parameter H01 screen. Scroll down and select the H02:Output Value function and push Enter.

Step 6) The value shown is flow in percent of the total span of 100gpm. Test the output of the meter with this value.

of 129



For example, to test the flow meter at 50gpm, enter data as 50%. To enter data, push 5 – Push 0 – Push Enter.

For example, to test the flow meter at 75gpm, enter data as 75%. To enter data, push 7 – Push 5 – Push Enter.

The value entered in the H02 panel will force the output of the meter to go to that value regardless of the actual flow. In this mode, the entire flow meter loop can be checked out as all instruments connected to the loop should be functioning as per the entered value in this step.

Step 7) After testing is complete, push the Left Arrow key and the display will go back to the parameter H01 screen. Push Enter.

Step 8) Highlight NORMAL.

Step 9) Push Enter twice. The screen will blink; confirm the correct data was entered by viewing the data in the display.

7.11.1 I/I Transducer Setup

Step 10) Push OK and push Home or ESC until the cursor is at the Home Menu Panel.

7.11. CURRENT OT CURRENT (I/I) TRANSDUCER

The Wilkerson model MM4380A signal isolation transmitter (I/I shown on drawing EC4, line 642) provides an

isolated 4-20ma signal output directly proportional to the 4-20ma input signal.

Setup of the MM4380A is accomplished by placing jumpers inside the module in the desired positions. First

remove the cover of the module to expose the jumpers then proceed with the following steps.

Step 1) Place the “INPUT” jumper, far left side, in the “MA” (upper) position.

Step 2) Place the “INPUT SPAN” jumper, left center, in the “.5V/25ma” position.

Step 3) The “INPUT CANCEL OFFSET % SPAN” requires two jumpers. One jumper is placed at the “25”

position and the second jumper is placed in the “ELV” position.

Step 4) Place the “OUTPUT SPAN” jumper in the “4-2-“ position.

Step 5) Place the “OUTPUT MA/V” jumpers, two jumpers required in this position, in the “MA” position.

of 129



Step 6) Place the “OUTPUT MORN/REV” jumper in the “NORM” position.

This completes the setup of the MM4380A module for this application. Replace cover and install module in relay

socket provided.

7.11.1 I/I Transducer Calibration

Calibration of the MM4380A module is accomplished simply by applying a current source, of known accuracy, to

the input of the module and adjusting the output with the zero and span pots accessible through the hole in the

module cover.

Note: All range select jumpers must be set in their proper positions and 120VAC must be present for pins 1 and 3

before calibration is started. An alternative to using the current source test meter as described below would be to

configure the flow meter for a loop test as described in the above narrative under the section Loop Test.

Step 1) Disconnect the flow meter output from the loop by removing the installed jumper from test points TP20 and TP21. Connect the Rochester Current test meter with the positive lead from the meter connected to TP20 and the negative lead connected to TP19. Set the meter to output 4-20ma in the source mode (simulates a 4-wire transmitter). Check to ensure that the module is seated securely in the base and 120VAC power is present at terminals 1 and 3 of the transducer.

Step 2) Disconnect jumpers TP32-TP-33. Connect a precision current meter to the output terminals TP-32 and TP-33. Set meter to read from 4.00 to 20.00ma.

Step 3) Adjust the current source to read 4.00ma on the input. Adjust the “Zero” pot until the meter on the Output reads 4.00ma.

Step 4) Adjust the current source to read 20.00ma on the input. Adjust the “SPAN” pot until the meter on the Output reads 20.00ma.

Step 5) Because the Zero and Span adjustments are interactive, the operator needs to repeat steps 3 and 4 until both readings are correct without adjustment of the zero or span pots.

Step 6) Disconnect current source and meter from the circuit, reinstall the jumper to TP20 and TP21 and TP-32, 33 and place module in service.

8.0 TELEPHONE DIALER SETUP AND CALIBRATION

8.1 Auto Dialer

The plant uses two Microtel Series 500 auto dialers, located in control panel CP-1, to monitor digital alarms and

analog signals. These auto dialers will automatically call pre-programmed telephone numbers to report alarm

and/or abnormal plant operating conditions. The auto dialers can also be accessed, via telephone, to report

operating, status of all programmed channels. The auto dialers have an extensive setup, initializing and

programming procedure that requires a thorough understanding of the “Installation and Operating Manual”. The

following procedure is an outline of keystrokes and tables of programming data required for the Multnomah Falls

WWTP. Reference to the installation and operating manual is necessary for detailed descriptions and visual aids

of the functions being programmed.

8.2 Operation

The auto dialers have the capability to allow remote monitoring and programming of each of its functions. The

following instructions are given to allow remote monitoring of each digital and analog input and output variable

to allow real time monitoring of plant functions. Care must be used when using the remote access as operational

data can be changed if correct procedures are not followed. To modify operational data and for other features not

listed below, reference the Micro-Tel maintenance manual located in the Operating and Maintenance Instructions,

volume no.2.

8.2.1 Remote Access Monitoring

Step 1) To initiate access to each dialer, first call the telephone number assigned to the dialer. For Dialer no.1 call (1) 503 695-2366 and for Dialer no.2 call (1) 503 695-2369.

Step 2) After the telephone rings the preset required number of rings (currently, 1), the called dialer will answer. If no alarm conditions are current, the dialer will answer with the message “Status Normal”. The dialer will repeat “Status Normal” three times during which the caller must acknowledge with an acknowledgement key (*) or the dialer will hang up.

of 129



Step 3) After the acknowledge key (*) is pressed, the dialer will respond with system advisory messages followed by “Enter Access Code”. The operator must then enter a preset access code (currently 1 2 3 4). If the code is entered successfully, the dialer responds with “Access Code Accepted – System Ready” after which the caller can than begin the remote monitoring process. The caller has 2 minutes in which the monitoring process must begin or the dialer will automatically hang up.

Note: At any time during the following process, using the asterisk key (*) on the telephone pad will cause a dialer to abort and terminate entries or procedures and return the remote operation procedure to a previous level.

Step 4) After hearing the “Access Code Accepted – System Ready” message, the caller then must enter a number key on the telephone pad that corresponds to the function desired as per the below list:

0. System Category.

1. Digital Input Category.

2. Analog Input Category.

3. Digital Output Category.

4. Intercom Category.

5. Voicemail Category.

6. Telephone List Category.

7. Telephone Directory Category.

Note: For the purpose of these instructions (monitoring system I/0), the caller must then enter no.1, 2 or 3 on the telephone key pad. For instructions to the other options listed above, reference the Micro-Tel maintenance manual, Remote Operation Procedure Flow Chart (page 54) located in the Operation and Maintenance Instructions, volume no.2.

Step 5) For the purpose of this instruction, category no.2 above will be used for an example. After entering no.2, the message from the dialer will be “Please Select the Analog Input Channel”.

Step 6) As an example, analog input channel no.06 will be used which is the Digester Blower Pressure for DB-02 (PT-4 as shown at line 2170 on schematic drawing EC16 for panel CP-1). For other analog channels, reference the list of Analog Input Channel Parameters given at the end of these instructions and also reference the schematic drawings. After the caller enters no.06 on the keypad, the dialer then reports “Analog Input Channel 06 Ready”.

of 129



Step 7) The caller next enters no.2 on the keypad and the dialer responds with the message “Analog Input Channel 06 is Normal (or “in Hi Alarm” or “in Lo Alarm” if in an alarm state), the reading is (the current reading is given)”.

Step 8) To monitor other channels, the caller must push the asterisks key (*) and the dialer will respond with “Please Select the Analog Input Channel” at which time another analog channel can be selected as per the list of Analog Input Channel Parameters.

Step 9) If a digital input or output channel is to be monitored, the caller will once again press the asterisks key (*) after which the dialer answers with “Please Select the System Function”. The caller then selects either no.1 (Digital Input Category) or no.3 (Digital Output Category). The process is then repeated as per the analog example given above.

Step 10) After the caller is through monitoring all desired channels by repeating the above process, he can either hang up or not respond for two minutes and the dialer will then disconnect and hang up.

8.3 System Tests

The following tests check for proper operation of the speech producing equipment of the system. These tests can

be performed anytime a problem is suspected in the speech synthesizing function. Step 1) Press the “HALT” key to display the system status screen, then press “SEQUENCE” to display the

1.22.40.08 Analog Input Channel zero calibration

The zero point for accurate LCD screen display must be adjusted and calibrated. On each analog card, a single

pot for each analog channel is provided to ensure that the value of the analog signal is displayed accurately on the

dialer LCD screen. The following calibration procedure is given to provide the zero adjust function:

Step 1) From the System Status screen, move the cursor until the analog card that is to be calibrated is highlighted and push “SELECT”. At the displayed screen, the analog value of each analog channel on the selected card can be viewed on the screen.

Step 2) Next connect the Rochester current generator to the analog input terminals of the analog channel to be calibrated. Connect the positive and negative wires from the generator to the positive and negative terminals respectively of the analog card. Turn the current generator to source mode and generate a 12 ma (50%) signal.

Step 3) On the LCD display, view the analog value for the channel being calibrated. The reading should be at 50% of measured value. For example, for Dialer No.2, card slot #3, input channel #1 the full scale value for LT1 is from 00000 to 02310 feet with decimal of 2. This means that the channel is reading from 0 to 23.1 ft and with the current generator at 12 ma (or 50%), the LCD display for the channel should be reading at approx. 11.5 ft which is 50% (or 12 ma) of the full scale value of 23.1 feet.

Step 4) If displayed value is not at a 50% value of the monitored analog input signal provided by the current generator, adjust the zero pot on the analog input card clockwise to decrease the value displayed on the LCD screen or counterclockwise to increase the value.

Step 5) After adjusting the pot until the displayed value equals approx. 50% of the normal operating value of the channel, disconnect the current generator and reconnect the field wires to the transducer ensuring that each wire is correctly reconnected to each terminal.

Step 6) Either return the LCD screen to normal viewing mode or move the curser to the next analog channel to be adjusted and repeat the above procedure.
