Troubleshooting and Test Functions
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.
• Leak sensor not connected to the detector main board.
• Defective leak sensor.
