Troubleshooting and Test Functions
Compensation Sensor Open
The ambient-compensation sensor (NTC) on the CSM board in the nano pump
has failed (open circuit).
The resistance across the temperature compensation sensor (NTC) on the CSM
board is dependent on ambient temperature. The change in resistance is used
by the leak circuit to compensate for ambient temperature changes. If the
resistance across the sensor increases above the upper limit, the error
message is generated.
Probable Causes
• Defective CSM board.
Suggested Actions
34
Exchange the CSM board.
