32 1100 Series Nano Pump Service Manual
2 Troubleshooting and Test Functions
Leak Sensor Open
The leak sensor in the nano pump 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 CSM board.
• Defective leak sensor.
• Leak sensor incorrectly routed, being pinched by a metal component.
Suggested Actions
✔ Ensure the leak sensor is connected correctly.
✔ Exchange the leak sensor.
