Fan Failed; Leak - Agilent Technologies 1290 Infinity II 2D-LC User Manual

11 Error Information
General Error Messages

Fan Failed

Error ID: 0068
The cooling fan in the module has failed.
The hall sensor on the fan shaft is used by the mainboard to monitor the fan
speed. If the fan speed falls below a certain limit for a certain length of time, the
error message is generated.
Depending on the module, assemblies (e.g. the lamp in the detector) are turned
off to assure that the module does not overheat inside.

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.
