1100 Series Nano Pump Service Manual 35
Troubleshooting and Test Functions 2
Compensation Sensor Short
The ambient-compensation sensor (NTC) on the CSM board in the nano pump
has failed (short 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 falls below the lower limit, the error message is
generated.
Probable Causes
• Defective CSM board.
Suggested Actions
✔ Exchange the CSM board.
