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.

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).

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.

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.
