SECTION 1 INTRODUCTION1-1 General Description

Sections 1 through 8 of this manual describethe wiring, programming and functionality ofthe standard Batch controller. Section 9 describesthe wiring, programming and functionalityof Batch controllers with software version8.7 (Option 6). Software version 8.7 incorporatesRemote Start, Stop & Reset with EZPRE (easy preset). EZ PRE is a useful toolfor applications that require frequent changesto the Preset amount.The Batch controller uses the following software

versions:VER 8.7 (Basic unit; Remote Start, Stop

& Reset with EZ PRE EasyPreset)VER 12.0 (Option 4; 16 point linearization)1-2 Typical ApplicationThe above application involves liquid flow.

The start button is pushed and the Batcherreceives pulses from the flowmeter. Thepulses are scaled by the K Factor and sentout via the pulsed output to an externalcounter. The Analog output is directed to astrip chart recorder which gives a hardcopy ofthe rate. As the Prewarn is reached, thecontrol valve partially closes. When the finalPreset is reached the valve shuts down completely.At any time the flow can be suspendedby hitting the stop button. Through

the serial communications, a computer keepsa record of the daily events.123456

1-3 Principles of Operation

PresetsWhen the start button is pushed, two relaysengage simultaneously to start flow. Whenthe prewarn number is reached, one relaydrops out. When the preset number isreached, the other relay drops out. The usermay enter the two numbers when setting upthe batch counter. The prewarn is set a certainnumber of counts less than the presetnumber. If the prewarn is set larger than thepreset, the message "PREWRONG" will appear

on the display.RatemeterAccurate to 5 1/2 digits (1 display digit). Theratemeter can be programmed to accept almostany number of pulses per unit of measurement,sample from 2 to 24 seconds maximum,and auto range up to 6 digits of significantinformation. The ratemeter with a K Factorof 1 displays the rate of pulses per second.Simply dial in the proper K Factor to display inminutes, hours or other units of measurement.

Press the C button, while the unit is displayingthe batch, to display the rate; 'R' is displayed


6/128

on the left side of the display.K FactorThe K Factor is used to convert the inputpulses or analog input into workable units.The 8 digit K Factor is a divider with a range

of 0.00011 to 99999999 (the decimal pointmay be keyed into any position). Separate KFactors may be entered into the count andrate sections of the Batcher. Thus, you maybatch in gallons and display rate in liters perhour. The maximum factored count speed is20000 Hz. The maximum factored rate is 7digits.16 Point Linearization (Optional)This option extends the accurate range by allowingusers to dial in different K Factors for

different input rates. This option may be usedwith digital or analog inputs. (See Section 7-3.)2

1-3 Principles of Operation (continued)CounterThe maximum count is 99999999. In thesetup mode choose "RO" (Reset to Zero) foradding (count up) operation or "SP" (Set toPreset) for subtracting (count down) operation.At any time, the display can be madeto flash the Grand Total by pressing the ENTbutton while in the run mode. Activating theCLR button while the Grand Total is flashing,resets the Grand Total counter.LockoutUnauthorized front panel changes can be preventedby entering a user selected, four digitcode, in the "Lockout" mode. The status ofthe unit can be observed but "LOCK ON" appearsif changes are attempted. Entering the

code again returns the unit to "LOCK OFF"status.Analog Output (Optional)The Analog Output option is available on allunits except those with Square Law inputs.Controlled by an Open Collector transistor, itgives a 4 to 20mA (or 0-20mA) output whichcorresponds to predefined rate or total readings.In the Setup mode the user is promptedto set the low and high (4 to 20 mA) valuesand also decide if the analog signal will correspond

to the ratemeter or totalizer.A sinking driver generates a linear current


7/128

across the user's external device (such as astrip chart recorder, PLC, computer, externalmeter, etc). The Batcher can supply the 24VDC to power the current loop. (Connect pin15 to 13, Pin 16 is now +24 VDC with respect

to pin 12.) Connect Pin 16 to the + DC side ofthe external device and connect Pin 3 to -DCside of the external device.Frequency outThe Batcher generates a pulse out for eachfactored count. An NPN transistor output (Pin2), can drive external devices at rates of 10,200, 2000 or 20000 counts per second as selectedthrough the keypad menu. If the KFactor scaled inputs generate pulses fasterthan the output speed selected, an internal

buffer will store up to 9,999 counts before"DATALOST" flashes on the screen. This indicatesthat the counts being totaled and thescaled outputs may be incorrect. Note thatall counts stored in the internal buffer will bepulsed out at the selected frequency even ifthe counter is reset.Outcard (Optional)RS232 or RS422 serial two way communicationsare available. Up to 15 units can belinked together in parallel and addressedseparately to transmit unit status or acceptnew set points in the standard ASCII format.Baud rates of 300, 600, 1200, 2400, 4800 or9600 as well as choice of odd, even, space,or mark parity can be selected by keypad control.3

STD PRE and EZ PRE Operation ModesVersion 8.7 of the batcher software allows the user to choose between STD PRE(Standard Preset)and EZ PRE (Easy Preset) operation modes. STD PRE operation is well suited forbatch amounts

that do not change, since the program mode must be entered to change the preset andthe batchcount must be cleared before starting a new batch. EZ PRE has been designed forusers whofrequently change the batch amount. During EZ PRE operation, the preset can beviewed andchanged without entering the program mode and another batch can be started withoutresetting theunit.Note: Before a batch is started and after a batch is complete, the unit will continue tototalize allinputs.Note: EZ PRE is not available on units with 16 Point Linearization.Using STD PRE

CLRWeighted AveragingVersion 8.7 of the batcher software includesweighted averaging of the rate display. Weightedaveraging is not available on units with 16 PointLinearization.Weighted averaging can be used to create a morestable display when the rate input is fluctuating. Aweight, W, from 00 to 99 is applied to the oldrate data before the new rate data is sent to thedisplay. The following equation is used:W = Weight (00-99)If a weight of 00 is used, the new rate data will go

directly to the display without being averaged. If anumber other than 00 is entered for the weight,then the new data will be averaged with the olddata before being sent to the display. Higherweight numbers will create a more stable ratedisplay. Small rate changes will be morenoticeable when lower weight numbers are used.Programming Weighted Averaging1. In the Program Mode, got to the RATE sub menuand program the K-FACTOR, the WINDOW, andthe SIG FIG parameters.2. When the display shows WEIGHTXX (XXrepresents the current WEIGHT value), either

3-9 Frequently Asked Questions AboutSetting Up The BatcherQ. Is there any way to backspace if the wrongbutton is hit by accident?

A. No, you can depress the CLR button andstart entering the number all over again or


21/128

press ENT repeatedly until back in the Runmode and start over again from there.Q. Is there any way to put a decimal point in anumber such as a preset or K Factor?A. Yes, simply press the D button after the digit

that you would like the decimal point. It willappear to the right of the digit.Q. Is there any way to enter a negative numberfor one of the Presets or K Factors?A. No, negative values are not allowed.Q. Is there any way to ruin the unit or completelyerase it by entering a bad number?A. No, if a number or entry is not valid the unitwill ignore it or flash an error message.Q. If the unit does not have serial communicationsor analog out, does the OUTCARD and

ALG OUT sections of the menu still have tobe set up?A. No, there are default settings from the factoryalready in the unit. No setup of thesemenu items is necessary for normal operation.Q. Does the Batcher have to be told what typeof input it has connected to it?A. No, The input signals are conditioned inhardware. This allows the input cards to beinterchanged without modifying the software.Q. If CLR is not pressed, numbers can still bewritten over the Presets or K Factors. Willthese numbers be accepted if the ENTbutton is pushed?A. No, in order for a Preset or K Factor to bechanged, the old number must be clearedout first by depressing the CLR button.3-8 How to ProgramThe initial programming of the unit is accomplishedby first depressing the MENU button.After pressing the MENU button once, the

display will read preset. To cycle to the nextcontrol parameter option, merely press theMENU button and Prewarn will appear on thedisplay. If the user does not wish to choosethis section of the menu, depress MENU buttonagain and the next control or parameterwill appear.Selection of all MENU control parameters isaccomplished through the routine describedfor Preset.The following is the sequence for entering a

Preset quantity.1. Depress the Menu D button once. The


22/128

display will read MENU. After a one secondpause the display will read PRESET.2. Depress the Enter ENT button; the displaywill flash indicating that you are not inthe Run Mode and not displaying the current

batch total.3. If the batch size is satisfactory, depressthe ENT button. This value will be enteredinto memory. Simultaneously, the unit willreturn to the Run Mode.4. To change the preset value, depress theCLR button and enter new number. Example:Suppose "250" is the new batchsize. Press CLR, then 2 , then 5 , then 0 .When the display holds the desired value,depress the ENT button. The new batch

SECTION 4 INPUTS4-1 Digital Pulse Inputs (Terminal 4)Digital Pulse Inputs: The input board is aseparate board that is plugged into the motherboard just behind the display. All digitalinputs are on the same board. There are fourdip switches on the board. The input conditioningcharacteristics may be altered bychanging the dip switches. A valid pulse isone which makes a transition from the offstate (low) to the on state (high): a positivegoing edge. The off state is 0 - 1 VDC withrespect to Terminal 12 (Ground). The onstate is 3 - 30 VDC with respect to Terminal12. The input impedance is 10 K ohms. At30 VDC, the current draw will be 3 mA. Thisshould be the maximum current that theBatcher will draw. Acceptable pulse width is

determined by the dip switch settings (SeeTable 4-1 below).DIP SWITCH SETTINGSTable 4-1SW1 SW2 SW3 SW4 ConditioningON ON --- --- 0-40 Hzmin. 12.5 msec on/offON OFF --- --- 0-400 Hzmin. 1.25 msec on/offOFF OFF --- --- 0-20000 Hzmin. 0.25 usec on/off--- --- OFF OFF needs sourcing input(drive input high)--- --- OFF ON needs sinking input(pull input low)ONS1 S2 S3 S4

4-1 Digital Pulse Inputs (continued)4-1.1 STANDARD: High Impedance (Terminal4).Has a 10 K Ohm pull down resistor to ground(Terminal 12) and must be driven high. Typicaldrivers include a contact closure from a 3-30 VDC source (such as Terminal 13), a PNPtransistor (proximity switch or other device) or

an amplified signal from an inductive pickup.Remember, the input signal must be referenced


40/128

to Terminal 12 of the Batcher. (SeeSection 2-5, Fig. 2-2 Typical Digital WiringConnections)4-1.2 High Impedance with pull-up (Terminal4).

Has a 4.7 K Ohm pull up resistor to +5 VDCand must be pulled low. Typical drivers includea contact closure to Ground (such asTerminal 12), or an NPN transistor (proximityswitch or other device). Remember, the inputsignal must be referenced to Terminal 12 ofthe Batcher. (See Section 2-5, Fig. 2-2 TypicalDigital Wiring Connections)Idea: This input works well with TTL devices.4-1.3 Reset Input (Terminal 5)Identical to the Standard, High Impedance Input

with one exception. The input speed isfixed for a minimum pulse width of 5 msec.Note: The reset input will not be changed toa sourcing type of input even if the dip switchis set for pull up or is changed to the pull upsettings.4-2 Analog Inputs 5A - 5E, 6A (Terminal 4)The input signal modules are mounted, justlike the Digital board, behind the display.Analog inputs all use the same board, likewiseso do the Analog-In/Out inputs. Theseboards are not field modifiable (unlike theDigital board). Each board is calibrated at thefactory for its particular input type.31

4-2 Analog Inputs (continued)

4-2.1 5A: 4-20 mA; 250 input impedance.5B: 0-20 mA; 250 input impedance.5C: 1-5 VDC; 15 K input impedance.5D: 0-5 VDC; 15 K input impedance.5E: 0-10 VDC; 15 K input impedance.

The above inputs take the analog signal andscale it from 0 to 10000 pulses per second byusing a highly linear voltage to frequency converter.These pulses go to the processor tobe scaled by the K Factors. To determine theK Factor, see Section 7, Calculating the KFactor.

4-2.2 6A: Square Law: 4-20 mA; 250 inputimpedance.The Square Law input is a special input thatcompensates for non- linear input types. Specifically,

inputs that require square root extractionto provide accurate count and rate determinations.

Observe proper precautions!a) Set the ratemeter at 6 SIG FIG; thewindow at 01; and the K Factor at 1.00.b) Remove the case and locate the analoginput card mounted behind the display

(see Section 6-3).c) Locate the two 0.3 inch square pots R3and R15. These numbers should besilkscreened underneath them on theboard.d) Input a very accurate low signal andadjust R3 (left side from the front) so thatthe display reads .0001 to 0000.e) Input a very accurate high signal andadjust R15 (right side from the front) sothat the display reads 9999 to 10000.

f) Repeat steps d and e until the unit isreading as close as possible to 0000 on


42/128

the low side and 10000 on the high side.This should only take a few tries.g) Re-case the unit and setup the Menu asdesired.If problems occur during calibration please contact

the factory for exchange or to arrange forfactory calibration.32

SECTION 5 OUTPUTSThe Batcher has five different possible types ofoutputs for controlling external devices or monitoringthe rate and totals. They are: FrequencyOutput, Relay Outputs, Open Collector Outputs,and Optionally available Analog Output (notavailable on models with (Square Law input),and RS232, RS422, or RS422M Serial Communications.

5-1 Frequency Output (Terminal 2)5-1.1 Electrical Characteristics of FrequencyOutputThe Batcher generates a pulse out for eachfactored count. A sinking NPN transistor output(see Figure 5-0.1), can drive external devices atvarious rates selected through the keypadmenu see Table 5-0.2 below). The Open Collectorsinks 30 VDC maximum to 1 volt maximumwith a maximum current of 100 mA.Speed (Hz) 10 200 2000 20000Min. on/off (msec) 47.5 2.0 0.2 0.013Table 5-0.2Applications: Remote totalizers, ratemeters orother monitoring devices.10 Hz: Electromechanical totalizersProgrammable Controller inputs200 Hz: Electronic totalizersProgrammable controllers with highspeed input cards.2000 Hz: High speed totalizers.

20000 Hz: High speed totalizers.4-3 DC Power Inputs (Terminals 12, 14)The Batcher may be powered by an external DCpower supply. The supply must provide 12 - 27Volts DC and at least 280 mA of current. Thepositive side (+DC) of the DC supply should behooked to Terminal 14 and the negative (orGround) side to Terminal 12.NOTE: Units powered by DC Voltages do nothave an isolated voltage out on Terminals 15and 16 or +12 VDC on Terminal 13.

4-4 AC Power Inputs (Terminals 17, 18)The Batcher may be ordered for 110 or 220 VAC


43/128

power. The unit requires single phase 50/60 HzAC power.The voltage range is 15% of the rated voltage.Voltages below this range will not power theunit. Voltages above this range may damage

the unit. The Batcher is relatively immune fromelectrical noise on the AC lines. However, inextremely noisy applications some line conditioningor filtering may be necessary. If fusing isrequired, external fusing must be supplied.Note: The Batcher has no internal fuse to blowout. If the unit does not function when power isapplied, contact the factory for assistance or toarrange for repair.Caution: An external fuse is required:DC Power: 0.5 Amp

AC Power: 0.125 Amp

!33

5-1.2 Internal Buffer for Frequency OutputAn internal buffer will store up to 9,999 counts ifthe scaled input generates pulses faster thanthe output speed selected. The warning message"DATALOST" flashes on the screen whenthe buffer overflows (see Section 6-1, WarningMessages). This indicates that the counts being

totalled and the scaled outputs may be incorrect.Note: All counts stored in the internal buffer willbe pulsed out at the selected frequencyeven if the counter is reset before it isfinished sending them.Figure 5-0.15-2 Control Outputs5-2.1 SPDT Relay Version (Standard)When the start button is pushed, the two relaysengage simultaneously to start flow. When theprewarn number is reached, one relay drops

out. When the preset number is reached, theother relay drops out. The user may enter thetwo numbers when setting up the batch counter(see Section 3-3, Menu Items 1 and 2). Thecontacts are rated at 10 A, 120/240 VAC or 28VDC.5-2.2 Open Collector Version (Terminal 19,20).The NPN, Open Collector Transistors, sink amaximum of 250 mA at 30 VDC when active.

They behave in the same manner as the RelayOutputs (see Section 5-2.1 above). TheOpen Collector outputs are available on units


44/128

with relay outputs, but, please observe the followingprecautions.Note: When relays are used, 10 VDC is providedat the transistor outputs throughthe relay coils. If current greater than

2 mA is drawn, the relay will remainenergized. Applying greater than 10VDC to the Open Collector outputsmay destroy the unit. The transistorwill sink 100 mA in the "ON"state with relays installed.5-3 Optional Analog Output (Terminal 3)5-3.1 Electrical Characteristics of AnalogOutputThe Analog Output option is not available onunits with Square Law inputs. Controlled by

an Open Collector transistor, it gives a linear4 to 20 (or 0 to 20) mA sink which correspondsto displayed rate or total readings. Asinking driver pulls a current to ground, acrossthe user's external device (such as a stripchart recorder, computer, external meter, etc).In the Setup mode the user is prompted to setthe output to correspond to rate or total andset the low and high (4/0 to 20mA) parametersto which the analog signal will correspond.Idea: The Batcher can supply the 24VDC topower the current loop. (Connect pin15 to 13, Pin 16 is now +24 VDC withrespect to pin 12.) Connect Pin 16 tothe + DC side of the external deviceand connect Pin 3 to -DC side of theexternal device (see Figure 5-2.1).34

5-4 Optional RS232 / RS422 Serial CommunicationsThis option allows the Batcher to act as a slaveto a master terminal. It may be accessed for

counts, rate, presets and K Factors. Up to 15units can be linked together in parallel andaddressed separately to transmit unit status oraccept new set points using the standard ASCIIformat. Baud rates of 300, 600, 1200, 2400,4800 or 9600 as well as choice of odd, even,space, or mark parity can be selected by keypadcontrol.

Input speed.b) Change your OUT FREQ settings tohandle a higher count speed (Section 3-3, Menu Item 7).c) Change your count K Factor to a largernumber, since the output frequency isbased on the factored count (Section 3-3, Menu Item 3).6-1.3 RFFFFFFFIndicates that the factored input rate has exceededa 7 digit number. The ratemeter cannothandle numbers larger than 7 digits (i.e.9999999). Change the Rate K Factor to a largernumber (Section 3-3, Menu Item 3) to correctthis problem.6-1.4 LOCK ONIndicates that the unit has been locked out! Theunit must be unlocked before any changes canbe made. See Section 3-3, Menu Item 4 to

The display will continue to display thismessage until the error is corrected. To correctthe error see Section 3-3, Setup Procedure.6-1.6 SECURITYIndicates that no signal has come in for theduration time set in the Lockout menu. Lockoutcode must be entered before the unit will continue.

Section 3-3, Setup Procedure.6-2 Troubleshooting6-2.1 GeneralThe following troubleshooting procedures havebeen developed as an aid in locating defects.Not every possible problem has been listed, buta general isolation procedure for tracking downproblems has been given. A standard recommendationis the removal of power for 2 seconds.This allows the microprocessor to gothrough a reinitialization cycle at power up. If it

is determined that the unit is faulty, contact yourlocal Factory Representative or Sales Officeconcerning replacement. The Batcher is notfield serviceable and all repairs should be performedby the factory.6-2.2 ProblemsSymptom: Display will not light.Possible Cause: No power to unit, power to unitnot to specifications or bad connection betweendisplay board and mother board.

Test Procedure: See Specifications Section 1-4 for proper input voltages. Then;a) Check AC voltage input on terminals 17 &


47/128

18.b) (if DC Powered unit) Check DC voltage inputon terminals 12 & 14.c) Check connection of display board to motherboard

Corrective Action: If all checks okay, replaceunit.6-2.2 ProblemsSymptom: Unable to start batch.Possible Cause #1: Displayed Batch count alreadyexceeds the Preset value.Test Procedure: Check Preset value againstthe displayed value. If the Preset is less, go tocorrective action.

Corrective Action: Reset the unit by pressingthe CLR button or change the Preset to a

larger value.Possible Cause #2: Incorrect programming.Test Procedure: Check for programming errors,review manual.

Corrective Action: Reprogram unit as required.Possible Cause #3: Defective Circuit board orcomponent.Test Procedure: Press the Start button andcheck for relay action. An OHM meter acrossthe appropriate relay terminals should givethe proper indication. (Be sure to disconnectall power to the relay terminals first!)

Corrective Action: If no relay action replaceunit.Symptom: Unit not totalizing.Possible Cause #1: Incorrect programming.Test Procedure: Check for programming errors,review manual. For Example, if the KFactor is too large it may take some time beforea count is registered on the display.

Corrective Action: Reprogram unit as required.

Possible Cause #2: Input signal invalid.Test Procedure: See Specifications Section1-4 for proper input signals. Then use oscilloscopeto;a) Check Analog input on terminals 3 and12 for proper current or voltage levels.b) (if Digital unit) Check Digital voltageinput on terminals 3 and 12.

Corrective Action: If inputs check okay, replaceunit.36

cards, the case must be removed. Removeall power before opening the case. CMOSlogic is used so observe standard precautionsagainst damage by static discharge. On unitsRS232 or RS422, two screws on the back,

holding the top left connector, have to be removed.Next, remove the six (6) flat headscrews behind the front bezel and lift off thebezel assembly. Slide the main board displayout the front of the case by pushing from therear. Once modifications are made, reversethe procedure to reassemble the unit. Makesure that the main board is in the track. Thesix (6) screws that hold the panel must betight to seal the rubber keypad panel assembly,approximately 0.6 in-lb torque.

6-3.1 Input Card ModificationFollow the instructions for removing the casein Section 6-3. The Input card is mounted justbehind the display and plugs onto the 15 pinpost connector. Remove the board and makedesired changes. When installing the Inputcard, make sure that the component side ofthe board is facing the front and that the 15pin connector is mated properly and not offsetto the side. Replace the front panel per Section6-3.6-3.2 Serial Communications Interface InstallationFollow the instructions for removing the casein Section 6-3. The RS232, RS422 andRS422M cards have a 15 contact ribboncable that plugs into the female connectornext to the heat sink. Choose the proper Interfacecard. With components on top andsubminiature connector to the back plug inthe harness and mount the card on the four(4) standoffs provided. After the main board

is inserted into the case replace the frontpanel as per Section 6-3.6-4 MaintenanceThe Batcher does not require any "RoutineMaintenance" by the user. If a problemshould occur, and all troubleshooting procedureshave been exhausted, contact your localrepresentative or distributor (phone numberon cover of manual).SECTION 7 CALCULATING THE K FACTORS7-1 General

The key to accurate flow measurement withthe Batcher is correct scaling. The electronics

of the unit have been designed for stabilityand repeatability. Even the finest measuringdevice and equipment cannot make up for improperfactoring and programming. Due tothe complexity of the concept of K Factors,

this special section has been provided forthose who still find it hard to understand. Aseparate worksheet has also been providedwith this manual to help in calculating the KFactors. It is hoped, that between this sectionof the manual and the worksheet, that anyquestions you may have, regarding the K Factor,will be answered.7-1.1 What is a K Factor?The K Factor is a divider. This means that ifthe K Factor is greater than 1, it will diminish

any input signal. Conversely, if it is less than1, it will increase any input signal. The KFactor range of the Batcher is from 0.0001001to 99999999. This allows a wide range offactoring from greatly increasing (to display alarge value) to decreasing the input (to displaya very small value).37

7-2 Calculating the K Factors.The following steps are the recommendedprocedure forcalculating the K Factors. Takeyour time and go through the procedureslowly at first. After several tries you shouldbe fairly adept at calculating the K Factor forany given input.7-2.1 Calculating the K Factor for DigitalPulse Inputs.Step 1. Find out what value the pulses represent.This should be specifiedon your device or with its paperwork.

Example #1: 360 Pulses = 1 yardExample #2: 1 Pulse = 2 gallonsExample #3: 2000 Pulses = 1 m3Step 2. The Count K Factor is equal to thenumber of pulses per value fromStep 1 (PulsesValue).Example #1: Count K Factor = 360

Example #2: Count K Factor = 0.5 (1 pulse 2 gallons)Example #3: Count K Factor = 2000TIME CONVERSION CHART

7-2.2 Digital K Factor FormulasPulses = Base K FactorUnits ValueBase K Factor . = Count K FactorUnits Conversion FactorCount K Factor . = Rate K FactorTime Conversion FactorStep 3. Enter the Count K Factor. (SeeSection 3-3, Menu Item 3).Step 4. Modify the Count K Factor to reflectany time conversions for the rate

display to the Rate K Factor. Thisis done by dividing the Count KFactor by the Time Conversion Factor.If no conversion is necessaryskip this step and let the Rate KFactor be the same as the Count KFactor. USE THE TIME CONVERSIONCHART AS NEEDED.Example #1: Convert yds per sec to yds perhour.Rate K Factor = 3603600 = 0.100Example #2: Convert gallons per sec to gallonsper min.Rate K Factor = 0.560 = 0.0083333Example #3: No conversion necessary.Rate K Factor = 2000Step 5. Enter the Rate K Factor.(See Section 3-3, Menu Item 3)38

7-2.3 Calculating the K Factor for AnalogInputs.

Step 1. Find out what value the maximuminput signal represents. Thisshould be specified on your deviceor with its paper work.Example #1: 20 mA = 100 gal / minExample #2: 5 V = 10 ft / secExample #3: 10 V = 32 m3 / hrStep 2. The Rate K Factor is equal to10000 divided by the value fromStep 1.Example #1:

Base K Factor = 10000

100 = 100Example #2:


51/128

Base K Factor = 1000010 = 1000Example #3:Base K Factor = 1000032 = 312.5Step 3. Enter the Rate K Factor.(See Section 3-3, Menu Item 3).

Step 4. Modify the Rate K Factor to makethe time conversion to seconds forthe count display. This is done bydividing the Rate
