Leak Sensor Open

Error ID: 0083

The leak sensor in the module has failed (open circuit).

The current through the leak sensor is dependent on temperature. A leak is

detected when solvent cools the leak sensor, causing the leak sensor current to

change within defined limits. If the current falls outside the lower limit, the error

message is generated.

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.

Probable cause Suggested actions

1 Leak sensor not connected to the power

switch board.
