Leak Sensor Open

The leak sensor in the detector 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 Causes
• Leak sensor not connected to the VWM board.
• Defective leak sensor.
