General Error Messages
Compensation Sensor Short
Error ID: 0080
The ambient-compensation sensor (NTC) on the power switch board in the
module has failed (open circuit).
The resistance across the temperature compensation sensor (NTC) on the
power switch board is dependent on ambient temperature. The change in
resistance is used by the leak circuit to compensate for ambient temperature
changes. If the resistance across the sensor falls below the lower limit, the
error message is generated.
Fan Failed
Error ID: 0068
The fan in the autosampler module or in the sample cooler 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.
Probable cause Suggested actions
1
Defective power switch assembly
Exchange the power switch assembly.
2
Loose connection between the power
switch board and the main board
Check the ribbon cable between the power
switch board and the main board.
Probable cause Suggested actions
1
Fan cable disconnected.
Ensure the fan is connected correctly.
2
Defective fan.
Exchange fan.
3
Defective sample cooler fan
Replace the sample cooler.
4
Defective main board.
