7 Error Information
General Error Messages
Compensation Sensor Open
Error ID: 0081
The ambient-compensation sensor (NTC) on the power switch board in the
module has failed (open circuit).
The resistance across the temperature compensation sensor (NTC) on the
power switch 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
Error ID: 0080
The ambient-compensation sensor (NTC) on the power switch board in the
module has failed (open circuit).
The resistance across the temperature compensation sensor (NTC) on the
power switch 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.
