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) Low Batt
i) Exit Alarms and enter the Details screen. Press Test Batt. If test still fails continue:
ii) Check battery connection (inside rear battery access panel)
iii) Replace battery (Only with an approved Turbines, Inc. battery (P/N: 900120)
c) 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 screw driver, rapidly scratch coil below the threads on the bottom
surface.
(c) Observe CDS1000 counts or "signal" light slightly illuminates or flashes. If
yes, there is most likely a problem with the turbine meter.
d) RTD Short or RTD Open
i) Check temperature probe cable connection
ii) Check cable for any loose or frayed ends. If so, replace (P/N: 900039)
iii) Check temperature probe ohms: should be around 1060Ω at 60°F. If not replace RTD
(P/N: 900206)
e) 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 recertified.
ii) To reset the indicator, go to "Programming" follow instructions to reset maintenance
timer. Changes System Setting…5) 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 factory
ii) No wobble, if YES, STOP, consult factory
iii) Internals appear intact, if NOT, STOP, consult factory
c) Refer to the turbine installation and operation manual for further turbine maintenance.
