Xylem System 5000 User Manual - Manual (Page 131)

GOES not transmitting:
1- Check power to the GOES Radio, do so under a load (e.g. a transmission).
2- See if the GOES time is correct, if it is stopped, it indicates power to the radio was lost,
stopping the clock. The radio will not transmit if the GOES clock is not running.
3- Check all antenna wires.
4- Check antenna alignment.
5- Use a power meter to measure the power output of the radio and the reflected power.

Our experience with pressure transducers has taught us a lot about the problems associated with
field installed equipment. The following list of problems and possible solutions will undoubtedly
grow with subsequent revisions of this manual and may be helpful to you.
Troubleshooting
Intermittent Data:
1- Check power and ground connections. Moisture over time will oxidize and corrode connectors
and pins.
2- Verify power supply or battery voltage. As the power supply approaches the lower threshold
of the System 5000
™
supply range, it may begin to miss readings intermittently.
3- Check the last system reset for a possible malfunction or clue to the problem.
Wrong or Erratic Data:
1- Check the sensor Properties screen for possible errors.
2- Verify slopes, offsets, or custom functions.
3- Check battery voltage and all connections.
General Data Collection
No SDI-12 Response:
1- Verify power to the System 5000
™
.
2- Check all SDI-12 connections, including DATA and GND.
3- Check the pin out of the SDI-12 sensor for correct wiring.
4- Make sure all sensors have a unique address.
