F.4 Troubleshooting
Below are some commonly experienced problems along with possible remedial action. Contact
the factory if any problem remains unresolved or additional help is required.
Symptom: A particular channel on the multiplexer appears to be malfunctioning:
Check sensor connections on the terminal board. Clean if corrosion exists.
Try moving the sensor wired to the suspect channel to another channel to verify the
malfunctioning of the channel (as opposed to the sensor).
Symptom: No channels are working:
Inspect circuit board for shorts, opens, or other damage.
Is moisture present on circuit board? If so, install desiccant to absorb.
Symptom: Channel selection appears to be random:
Has corrosion built up on the circuit board? Clean if necessary.
Is there a source of electrical noise nearby? Move multiplexer or noise source if possible.
