Troubleshooting
1) Check the following:
a. All connections are secure.
b. Cables are not split or frayed.
c. Power source is connected to the truck battery.
d. No moisture is present in connectors.
2) If the unit is able to run in Operating mode, observe "ALARM" list by pressing "D".
a. Low Power:
i. Check power connection.
ii. Check power source (must be equal to or greater than 9Vdc).
b. Coil Short or Coil Open:
i. Check signal cable connections (both ends).
ii. Check cable for any loose or frayed ends. If so, replace (P/N: 900038)
iii. Check Coil Operation:
1. Check coil Ohms: should be greater than 500Ω or less than 3000Ω
(Ohms).
2. Perform signal test:
a. Remove pickup coil from turbine meter. Reconnect signal cable
to coil.
b. With a screwdriver, rapidly scratch the coil below the threads on
the bottom surface.
3. Observe CDS2000 counts or "signal" light slightly illuminates or flashes.
If yes, there is most likely a problem with the turbine meter.
c. RTD Short or RTD Open
i. Check temperature probe cable connection.
ii. Check cable for any loose or frayed ends. If so, replace the cable. (P/N: 900039)
iii. Check temperature probe Ohms: should be around 1060Ω at 60°F. If not, replace
the probe. RTD (P/N: 900206)
d. Maintenance Due
i. This indicates the meter and turbine need to be recertified. This is based on the
amount of time the system has flowed product since it was last re-certified.
ii. To reset the indicator, go to "Programming" and follow instructions to reset
maintenance timer. Change System Setting…Maintenance.
3) Check turbine meter
a. Ensure the turbine is warm and under no pressure.
b. Remove turbine from line and observe the following:
i. Rotor spins freely; if NOT, STOP, consult with the factory.
ii. No wobble, if YES, STOP, consult with the factory.
iii. Internals appear intact, if NOT, STOP, and consult with the factory.
4) Refer to the turbine installation and operation manual for further turbine maintenance.
