Troubleshooting and Test Functions
Leak Sensor Short
Leak Sensor Short
The leak sensor in the quaternary pump 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.
Probable Causes • Defective leak sensor.
• Leak sensor incorrectly routed, being pinched by a metal component.
Suggested Actions ❏ Exchange the leak sensor.
