7 Error Information

General Error Messages

Leak Sensor Short

The leak sensor in the module has failed (short 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 increases above the upper limit,

the error message is generated.

Leak Sensor Open

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.

Probable cause Suggested actions

1 Defective flow sensor.
