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.
• Defective leak sensor.
• Leak sensor incorrectly routed, being pinched by a metal component.
❏ Exchange the leak sensor.
