General Error Messages
Leak
Error ID: 0064
A leak was detected in the module.
The signals from the two temperature sensors (leak sensor and board-mounted
temperature-compensation sensor) are used by the leak algorithm to determine
whether a leak is present. When a leak occurs, the leak sensor is cooled by the
solvent. This changes the resistance of the leak sensor which is sensed by the
leak-sensor circuit on the main board.
Leak Sensor Open
Error ID: 0083
The leak sensor in the module 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 cause Suggested actions
1
Loose fittings.
Ensure all fittings are tight.
2
Broken capillary.
Exchange defective capillaries.
3
Leaking flow cell.
Exchange flow cell components.
Probable cause Suggested actions
1
Leak sensor not connected to the Power
Switch board.
Please contact your Agilent service representa-
tive.
2
Defective leak sensor.
Please contact your Agilent service representa-
tive.
3
Leak sensor incorrectly routed, being
pinched by a metal component.
Please contact your Agilent service representa-
tive.
4
Power switch assembly defective
Please contact your Agilent service representa-
tive.
