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 main board 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.
This limit is given by 2 revolutions/second for longer than 5 seconds.
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.
