PHYSICAL SIZE / WEIGHT NEMA4X A wall mountable fiberglass enclosure. FRONT PANEL Input Pulse Indicator A red LED that blinks on and off to display each pulse received from meter. NEMA1 NEMA4X Length 6.35” 5.9” Height 3.0” 5.9” Width 5.3” 3.8” Weight 2.4 Lbs 2.5 Lbs OUTPUTS AVAILABLE Power Indicator Standard Proportional DC Output: 4-20 mA A red LED located below the pulse indicator, indicating the instruments power supply is functional. All instruments are supplied with a 4-20 mA DC output proportion to the flow rate through the metering device. This signal has the capability of driving external equipment with an impedance from 0 to 500 ohms without recalibration. Totalizer / Flow Rate Indicator Displays both total consumed and flow rate on an eightdigit transmissive Red LED backlight 0.46” display. A single display indicates flow rate designated by an R. The accumulating totalizer is indicated by a blank and the resettable totalizer annuniciator is a b.The display can be toggled manually with the front panel SELECT switch or programmed to automatically to display flow rate and total consumed on the two available totalizers. The display may be left in either mode. The number of active digits depends on the parameters of the input signal. SPECIFICATIONS Input Signals General Requirements Input Frequency (full Scale) – 1 to 1000 Hz Maximum loop resistance – 40 ohms Duty cycle – 50/50 ± 20% Contact Closure Inputs Type – SPST ( contact bounce less than 5 ms, interrupting current – 50 ma max) Solid State Inputs Optional Outputs Option A: Dual 4-20 mA Output Signals: Two (2) 4-20 mA signals proportional to the flow through the metering device. With the standard 4-20 mA output, this option provides for a total of three (3) 4-20 mA signals. If isolation between devices is necessary an analog isolator is recommended. May require an enclosure upgrade. Option Bb: Totalized Contact Output A SPDT contact closure rated 5 amps, resistive 30 VDC or 250 VAC.

FUNCTION 7-16 Normally Open 8-17 Common 9-18 Normaly Closed OPTION K TERMINAL NUMBER FUNCTION 5 Positive 6 Negative For connections to options A, B C2 or D see option board insert. Error Indicators Electrical Connections Cnt OVEr — indicates that totalizer A has rolled over. Complete all connections to the metering device and instrument before applying power. If it becomes necessary to disconnect any of these connections, first remove the AC power to the instrument. bCntOVEr—indicates the totalizer b has rolled over. OLOLOL—indicates that the flow rate has exceeded the calibrated flow. Totalizer Over—To reset the totalizers back to zero (0) locate the three (3) pins connector in the corner of the PC board opposite terminals 12 through 15 (see connection diagram). TH-W-APK-00-00-0612-05-A Page 3 of 8 Remove the power from the instrument. Move the jumper on the left and middle pins to the right hand and middle pins. Reapply the power momentarily. Turn the power off and move the jumper back to the left and middle pins. Reapply the power; the totalizers should read zero (0). Flow Rate Over—There are a number of discrepancies that can cause the OLOLOL indication, listed below. • • • Instrument is calibrated for a different meter. Meter flow rate exceeds instrument calibration rate. Meter maximum flow capacity is exceeded. To eliminate a flow rate calibration problem check that the meter and instrument calibration agree. If recalibration is necessary refer to module #2 in the Instrument Recalibration Section. CntA dP – (Numeric selection depends on the factors determined below.) CntA ScF – (This factor equals the desired totalizer registration divided by the number of pulses for that registration. The number varies with each meter and registration. Example for a W2000 DRE meter reading in gallons. 500.9663 pulses equals 1000 gallons. Therefore, the factor is 1/500.9883 or 0.0019961. Only four(4) digits can be entered for the factor. Therefore, the number entered would be 0.0020, the factor rounded off. To improve the accuracy the decimal should be moved two (2) places and the factor becomes 0.19961. Since the decimal was moved two (2) places, the selection for CntA dP above is 0.00 and the factor entered into Cnt ScF is 0.1996. CntA rSt—to CtLd Calibrating The Readout CntA dir—NOr CAUTION: All instruments are preprogrammed to operate with the meter specified when ordered and no additional programming is required. Entering the program mode may cause erroneous operation. This should only be done when the operating specifications have changed. CntA Ld—000000 To enter the programming mode, depress and hold the SEL button on the readout for 2 seconds. In the program mode the display will show Pro and flash to nO. There are five (5) programming modules available. Press the RST button to step through the modules. When the correct module is displayed, press the SEL button to enter that module. Cntb Bat—nO Cntb dP – (Usually the same as CntA dP) If the units of measure are not the same use the procedure listed above to determine the decimal point location and factor. Possible examples are one totalizer reading in gallons and the second in cubic feet, cubic meters or imperial gallons. Cntb ScF – (Usually the same as CntA ScF, if not use the procedure listed above.) RSt P – UP – nO USEr InP – reset In the module the function being programmed is shown then flashes to the value presently entered for the function. USEr ASn – both A – b Pressing the RST button stops the display from flashing and places the unit into the data selection mode. Module #2 (2 – rAte) In the selection mode the operator presses the RST button to scroll through the parameters available for that menu. RAtE dP – The decimal location depends on the flow rate value. Typically is set to display the multiplier to use all six digits on the display. (This setting is determined below.) When the desired selection is displayed press the SEL button to store the data and advance to the next menu. When setting numerical values use the RST button to increment the flashing digit, and momentarily press the SEL button to advance to the next digit. To start the least significant digit flashing momentarily depress the RST button. To exit the programming mode and save all parameters step through the module until one of the five main modules is displayed, then press the SEL button until Pro nO is displayed. Pressing the SEL button at this point enters the data and closes the program mode. THIS PROGRAMMING PROCEDURE ONLY APPLIES 5 TO VERSION 3.0 AND 3.1 READOUTS. PROGRAM MENUS Module #1 (1 – input) InP A-b – dual Cnt RAtE Enb – yES RAtE dSP – This number represents the maximum flow rate to be displayed. In establishing this number, all 6 of the available digits should be used if possible. (This setting is determined below.) RAtE InP – (The Hertz value at the programmed flow rate. This number should be enhanced as follows: For a W2000 DRE the maximun flow rate is 2500 GPM. At 20.87 hertz. The 2500 could be used for RAtE dSP above, but to improve the accuracy it should be set to 25000. The decimal was moved one place to the right, the hertz value must also be moved one place to keep proportions the same. Therefore, RAtE dP should be 0.0, RAte dSP should be 25000.0 and the hertz set to 208.7. TH-W-APK-00-00-0612-05-A Page 4 of 8 LO – Udt – Set to 5.0. this sets the number of seconds between flow rate display updates. If the flow rate indicator is varying due to fluctuating meter signals, increasing this number reduces display fluctuations. May be set between 0.1 and 99.99 seconds. HI-Udt – Set to 90.0. Sets the number of seconds the instrument will wait for a meter pulse before going to zero (0). May be set between 0.1 and 99.9. If Count b was selected above set the value to represent the total number of counts on b that will occur before the relay actuates. SP1 Out—Nor SP1 LIT—Nor SPt P-UP – Set to SAVE. SP1 tYPE—Hi-Act Module #3 (3-dSPLAy) SP1 Stby– nO SEL Enb – Set to yES. SP1 AUtO—ZErO-Str RSt Enb - This step programs the counter(s) to be reset to zero (0) with the RST button. Typically set to Count b to reset the b totalizer with the RST button. To reset the A totalizer set to Count A, to make both resettable set to both A-b. When using option Bb the b counter must be set to reset. SP1 OFF2—nO d-ScroLL – Typically set to nO, set to yES to have the display automatically scroll between A total, b total and the flow rate. d-Color - Specifies the color of the display (Typically set to rEd, if green is desired set to Grn) d-LEVEL – Sets display intensity ( Typically set to 5, to reduce the intensity, reduce the number) Pro Code – Factory set to 124. Although a lock code is not necessary, it is an electronic lock to prevent tampering. It may be changed to any three (3) digit number. CodE VEr—nO FACt Set - Set to no. Setting to yES causes the program stored in memory to be erased. Module #4 (4-SetPt) This module is only active when options Bb or L are present. SPt SEL—SP1 SP2 Enb—nO SPt ASn – Set to rAtE for option L. Contact is then based on the flow rate. Set to Count b for option Bb. Contact output is based on quantity. SPt ACt – If rAtE was selected above set to BOUnd if contacts are to close when the flow rate equals or exceeds the set point and close below the set point. Set to LAtCH to hold the contacts closed once the flow quals the set point. A manual reset is required to release the latched contacts. For quantity applications where Count b was selected above set to t-OUt . SPt tOUt - Only active if t-OUt was selected above. SET the number of seconds that the relay remains closed each time it is activated. SPt VAL – If rAtE was selected above,set the actual flow rate where the contact closure is desired. SP2 OFF1—nO Ch-COLOR – Typically set to nO. Set to yES to force the backlight color to change when the setpoint output is activated. To activate set point 2. Set the first step SPt SEL to SP2 and the second step SP2 Enb to yES. Follow the above procedure starting with SPt ASn. Module #5— (5—SeriAL) The serial communications are only accessible when an optional RS232 or RS485 serial communications module is ordered in the instrument. A separate data sheet and programming is included with this option. Setting Option B Factors The option B factor is coded in binary and can be changed in the field to any whole number between 1 and 4095. To determine the factor the following procedure should be used. 1. Determine the quantity that the contact closure represents. 2. Determine the value of a pulse from the meter in either quantity per pulse (cubic feet/pulse) or pulses per quantity (pulses/cubic foot). 3. Determine factor as follows (assuming desired output is in 1000 cubic feet increments and meter output is 0.564 cubic feet per meter pulse). a. Calculate the pulses per cubic foot by determining the reciprocal of 0.564. 1/0.564= 1.7730496 Pulses/Ft3 NOTE: If meter data is available in pulses per cubic foot, this step can be eliminated. b. Multiply the pulses per cubic foot by the quantity to be indicated. (In this example 1000). 1.7730496 X 1000 = 1773.0496 pulses per 1000 ft3. c. Since the circuitry is only capable of handling whole numbers, the factor must be rounded to the nearest whole number (1773). TH-W-APK-00-00-0612-05-A Page 5 of 8 NOTE: When the factor is rounded , a small error is introduced, in this example .0028%. In applications where this error is not acceptable the addition of option I or using option Bb will reduce the error considerably. d. To set the factor on the option B on the option B board locate the 12 position dip switch on the board. To start, place all 12 switches in the off position. Setting the factor is accomplished by turning the dip switch ON so that the sum of the factors equals the number desired. There is a unique combination of factors for each desired number. They are determined in the following manner, select the largest binary number from the chart that does not exceed the balance, continue selecting and subtracting until the balance equals zero (0). At this point, all factors subtracted must be set into the instrument by placing the associated switch in the ON position. 3. Apply the formula noted in step #1 to determine the calculated Range capacitor value. Example: For a W2000 Turbo Meter at 2500 GPM. C = 1.54 / 20.874 C = .0738 microfards. 4. A .0738 microfard capacitor is not a standard, that cannot be procured. To be in the calibration range of the adjusting pots, the C value selected must be within 10% of the calculated valve. This may require paralling capacitors to reach the desired value. To achieve maximum adjusting range, the final value should be a close to the calculated value as possible. Example: The calculated value is .0738 microfarads, therefore, the final capacitor value must be within the 10% range of .0664 to .0810 microfarads. Although there is a standard .068 microfarad capacitor available, it is at the low end of the range. To move the final selection closer to the middle, the .068 microfarad capacitor should be paralleled with an .0068 microfarad capacitor increasing the value to .0748 microfarads. Because you are limited to available capacitor values and all capacitors have a tolerance some trail and error may be necessary if a capacitance meter is not available. 5. Install the correct capacitor values on the PC Board. The stability of the range capacitor affects stability of the converter; only polycarbonate or polystrene capacitors should be used. The D/A converter is factory set to a precise frequency to match the water meter or signaling device. If it becomes necessary to recalibrate the D/A converter, the following procedure must be followed and high quality test equipment used. Any component changes must be made with equivalent components. Range Capacitor Selection The range capacitor value is determined by the frequency output and the desired range for the meter that is driving it. To determine the Range Capacitor value: Test Equipment Setup (Using a milliampere meter) To calibrate the converter you need a signal generator with a digital readout and a digital VOM that can read milliamperes in the 20 milliampere range. A voltmeter can be used with a precision resistor. The signal generator must have a open collector or a switch output. See option 1. The typical signal generator has a pulse type output. To use this type of signal generator a switching type transistor must be connected between the signal generator and the instrument being calibrated. See figure #2. 1. Use the formula C range 1.54 / f (C value is in microfarads.) 2. Determine the full scale frequency value for the signal source. Exp. A 6” W2000 Turbo Meter outputs 20.874 hertz at 2500 GPM. If the 20 mA signal represents 2500 GPM then use 20.874 hertz for the (f) value in the above formula. If the 20 mA is to equal a lower flow rate then scale the frequency value to the lower requirement. For example assuming a desired maximum flow of 1500 GPM or 60% of the maximum flow range, the frequency at that flow rate is 60% of the 20.874 hertz or 12.524 hertz. 1. Disconnect the AC power to the instrument. 2. Disconnect any equipment connected to the 4 - 20 mA output terminals. 3. Connect a milliampere meter directly across the 4-20 mA terminals on the instrument. TH-W-APK-00-00-0612-05-A Page 6 of 8 4. Connect the signal generator to the instrument being calibrated. The plus output of the signal generator is connected to the Signal Input terminal of the instrument. Connect the minus or ground terminal of the signal generator to the Ground terminal of the instrument. The +12 VDC terminal is not connected. Using a voltmeter insure that the 12 VDC output is present. (See Figure#2) 5. Apply power to the instrument. 6. Set the signal out of the signal generator to 0 Hertz out. 7. Check the output current by placing a milliampere meter directly across the 4 - 20 mA output terminals. It should read 4 milliamperes, if it does not adjust the zero potentiometer until the meter reads 4. NOTE: The 4 - 20 mA signal does not respond immediately when the potentiometer is adjusted. Adjustment should be in small increments allowing time for the current to stabilize before further adjusting. 8. Set the signal generator to the full scale hertz value. The milliampere meter should read 20 milliamperes. If it does not, adjust the SPAN potentiometer to 20 milliamperes. Again, adjustment should be in small increments allowing time for the current to stabilize before further adjusting. 9. Return to step #6 and readjust the zero setting if necessary, then again check the full scale value. This process of checking the zero and full scale values may have to be repeated 4 or 5 times. The adjustment should be smaller each time until the final values are achieved. 10. Set the signal generator to half scale (50% of the full scale hertz). Check the milliampere meter, it should read 12 milliamperes. If it does not check zero and full scale again. If the 12 milliampere output can not be achieved, the circuit is not linear and can not be calibrated. It should be returned for repair. 11. Disconnect the milliampere meter and reconnect the water meter transmitter. Apply power. Test Equipment Setup (Using a volt meter) To calibrate the converter you need a signal generator with a digital readout and a digital VOM that can read voltage in the range determined by the resistor selected. The signal generator must have a open collector or a switch output. The typical signal generator has a pulse type output. To use this type of signal generator a switching type transistor must be connected between the signal generator and the instrument being calibrated. See figure #1 and #2. 1. Disconnect the AC power to the instrument. 2. Disconnect any equipment connected to the 4 - 20 mA output terminals. 3. Connect a precision resistor across the 4- 20 mA terminals on the instrument The resistor value can be between 1 to 500 ohms. The value selected depends on the voltage required by the external device being driven, resistor availability and the range of the voltmeter. For this procedure we used a 500 ohm resistor . The voltage out would be 2 (.004 X 500) to 10 (.020 X 500) volts. 4. Connect the signal generator to the instrument being calibrated. The plus output of the signal generator is connected to the Signal Input terminal of the instrument. Connect the minus or ground terminal of the signal generator to the Ground terminal of the instrument. The +12 VDC terminal is not connected. Using a voltmeter insure that the 12 Vdc output is present. (See Figure#2) 5. Apply power to the instrument. 6. Set the signal out of the signal generator to 0 Hertz out. 7. Check the output voltage by placing a volt meter directly across the resistor. It should read 2 volts, if it does not adjust the zero potentiometer until the meter reads 2 volts. NOTE: The voltage does not respond immediately when the potentiometer is adjusted. Adjustment should be in small increments allowing time for the current to stabilize before further adjusting. 8. Set the signal generator to the full scale hertz value. The volt meter should read 10 volts. If it does not, adjust the SPAN potentiometer to 10 volts. Again, adjustment should be in small increments allowing time for the voltage to stabilize before further adjusting. 9. Return to step #6 and readjust the zero setting if necessary, then again check the full scale value. This process of checking the zero and full scale values may have to be repeated 4 or 5 times. The adjustment should be smaller each time until the final values are achieved. 10. Set the signal generator to half scale (50% of the full scale hertz). Check the volt meter, it should read 6 volts. If it does not check zero and full scale again. If the 6 volt output can not be achieved, the circuit is not linear and can not be calibrated. It should be returned for repair. 11. Disconnect the milliampere meter and reconnect the water meter transmitter. Apply power. READ BEFORE CHANGING THE PROGRAM UNLOCK PROCEDURE The following procedures involve programming changes when making these changes use the Programming Menus. After making a change press and hold the SEL button for approximately 2 seconds to enter the change into memory. After making all changes always return to normal operation before removing power to permantely enter all changes into memory. To enter the program mode, press and hold the SEL button on the readout until it flashes Pro CodE (If it does not display PrO nO press the SEL button until it does) and flashes over to 000 with the least significant digit flashing. Press the RST TH-W-APK-00-00-0612-05-A Page 7 of 8 button 4 times to read 004 (if you exceed the desired number keep pressing the RST button until the number comes back to 4. When the 4 is displayed, press and hold the SEL button until the second digit starts flashing, reading 004. Press the RST button 2 times to read a 2 the readout should read 124. If it does not, repeat the above process until the proper code is displayed. When the correct code is displayed, press and hold the SEL button until the display flashes PrO nO. Setting the A Totalizer to a Preset Number. 1. Determine the number to be preset into totalizer A. 2. Go to Pro—nO If instrument is locked follow the Unlock PROGRAMMING OPTION L 1. Go to PrO nO. If instrument is locked follow the Unlock procedure above to unlock. 2. Press the RST button four (4) times the readout should read 4 SEtPt. 3. Press the SEL button once. Readout should read SPt SEL – SP2. If not press the RST button until it does. 4. Press the SEL button 2 times. Readout should read SP2 - ASn - rAtE. If not press the RST button until it does. 5. Press the SEL button the readout should read SP2 Procedure above to unlock. Act - bOUNd* or LAtCH**. If not press the RST button until it does. (See * and ** below) 3. Press the RST button once. 6. Press the SEL button one (1) time the readout should Go to Module #1. Display should read 1– INPUt. 4. Press the SEL button 4 times. Readout reads CntA rSt - to ZEro press RST to change to CtLd. 5. Press the SEL button 2 times the readout reads CntA Ld—enter the desired number to be preset. 6. Press and hold the SEL button for 2 seconds to enter number. 7. Press the SEL button to go to Pro—nO. 8. Press the RST button 3 times. Display should read 3 dSPLAy. 9. Press the SEL button 2 times. The readout reads RSt Enb - Count b 10. Press the RST button to change to Count A. 11. Press the SEL button to until the readout returns to normal operation. 12. Press the SEL button to go to Counter A. 13. Press the RST button. Observe that the desired number was entered into counter A. 14. Go to Pro-nO If instrument is locked follow the Unlock Procedure above to unlock. 15. Press the RST button once. 16. Go to Module #1. Display should read 1– INPUt. 17. Press the SEL button 4 times. Readout reads CntA rSt - to CtLd press RST to change to ZEro. 18. Press the SEL button to go to Pro—nO. 19. Press the RST button 3 times. Display should read 3 dSPLAy. 20. Press the SEL button 2 times. The readout reads RSt Enb - Count A . 21. Press the RST button to change to Count b. 22. Press the SEL button to return to normal operation. read SP1 - VAL and change over to a number. This is the flow rate where the set point will activate if acceptable press the SEL button if not change to the desired number and press SEL button. 7. If SP2- Act is set to LAtCH and you want to unlatch with the RST button on the front of the readout. 8. Press the SEL button 5 times. Readout should read SP2-rSt yES, if not set to yES with the RST button. In all other cases SP2-rSt should be set to nO. 9. Press the SEL button until the readout returns to normal operation. * bOUNd causes the relay to close when the flow rate equals or exceeds set point. If the flow rate falls below the set point the relay will open. ** LAtCH causes the relay to close when the flow equals or exceeds the set point. Once closed it will remain closed regardless of flow rate until the RST button is pushed. Change Counter A and/or Counter b Scale Factor 1. If the counter scale factor must be changed, this is accomplished in Module #1. 2. Go to PRO nO If instrument is locked follow the Unlock procedure above to unlock. 3. Press the RST button once the readout should read 1 - INPUt 4. See procedure for Module #1 in the Program Modules under CntA Scf. In the example the CntA ScF was 0.1996 with two (2) decimals entered under CntA dP. Following the same logic 50.09663 pulses equals 100 gallons, the reciprocal is 0.019961. To change to 100 gallon counts change CntA dP to 0.0 (one (1) decimal ) and leave CntA ScF at 0.1996. To change to 10 gallon pulses, change Cnt dP to 0 (no decimals). After completing, press SEL until the display shows Pro nO. Pressing it again will return the display to normal operation. The above procedure may be used for counter b by changing Cntb Scf and Cntb dP. TH-W-APK-00-00-0612-05-A Page 8 of 8 Reducing the value of the counter b allows for smaller quantities to be detected by option Bb. If the value of counter b is 1000 gallons the Bb option can only count in 1000 gallon increments. Setting the value to 10 gallons then any increment of 10 can be programmed. For example a 750 gallon contact closure would not be possible with 1000 gallon increments, but with 10 gallon increments with a set point of 75 ( SP1 VAL = 75) it can be achieved. Reducing the value of a count may cause a slight error in the total value. Programming Option Bb ( Pulse Width and/or Value) 1. Determine the factor to obtain the desired contact closure output. Example: For a W2000 DRE 500.96639 pulses represent 1000 gallons. To determine the factor, take the reciprocal of the pulses per 1000 gallons. (1/500.96639) = .001996) Totalizer Reset The electronic totalizer flashes “Cnt OVEr” to indicate that the totalizer has rolled over. When this occurs, a manual reset is necessary. With a NEMA4X enclosure, open the door. Locate the 3 pin connector on the printed circuit board; it is on the side of the board opposite the transformer above the mounting hole. There is a 2 place (blue or black) jumper on the 2 pins on the left side of the connector. Remove the jumper and place it temporarily on the center and right hand pins. This must be done with the power on, if preferable, turn the power to the instrument off before moving the jumper. After placing the jumper on the center and right pins, turn the power on; this resets the totalizer to zero (0). After resetting, move the jumper back to the orginal position. 2. Go to Pro nO. If instrument is locked follow the Unlock Procedure above to unlock. 3. Press the RST button four (4) times the readout should read 4 - SEtPt. 4. Press the SEL button once. Readout should read SPt SEL - SP1. If not read SP! press the RST button until it does. 5. Press the SEL button 2 times. Readout should read SP1 ASn - count b. If not press the RST button until it does. 6. Press the SEL button the readout should read SP1 Act t-Out. If not press the RST button until it does. 7. Press the SEL button the readout should read SP1 tOUt and change over to a number. This is the pulse width in seconds if acceptable press SEL if not change to desired number and press SEL button. 8. Pressing the SEL button above causes the display to read SP1 VAL and change over to a number. This is the number of counts on counter b that equal a pulse out. For example if counter b is reading 10 gallon increments and SP1 Val reads 100 this will create 1000 gallon pulses. (10 X 100 = 1000) 9. Press the SEL button until the readout returns to normal operation. © All products purchased and services performed are subject to Sensus’ terms of sale, available at either; http://na.sensus.com/TC/TermsConditions.pdf or 1-800-METER-IT.
