General Error Messages
Compensation Sensor Open
The ambient-compensation sensor (NTC) on the main board in the module has
failed (open circuit).
The resistance across the temperature compensation sensor (NTC) on the
main 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.
Compensation Sensor Short
The ambient-compensation sensor (NTC) on the main board in the module has
failed (short circuit).
The resistance across the temperature compensation sensor (NTC) on the
main 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 cause Suggested actions
