7 Error Information
Module Error Messages
Temperature Out of Range
Temperature Out of Range 0: Pump channel A
Temperature Out of Range 1: Pump channel B
One of the temperature sensor readings in the motor-drive circuit are out of
range.
The values supplied to the ADC by the hybrid sensors must be between 0.5 V
and 4.3 V. If the values are outside this range, the error message is generated.
Temperature Limit Exceeded
The temperature of one of the motor-drive circuits is too high.
The processor continually monitors the temperature of the drive circuits on
the main board. If excessive current is being drawn for long periods, the
temperature of the circuits increases. If the temperature exceeds the upper
limit, the error message is generated.
Probable cause Suggested actions
1 Defective main board.
Please contact your Agilent service
representative.
Probable cause Suggested actions
1 High friction (partial mechanical blockage) in
the pump drive assembly.
Ensure the capillaries and frits between the
pump head and damper inlet are free from
blockage.
2 Partial blockage of the flowpath in front of
the damper.
Ensure the outlet valve is not blocked.
3 Defective pump drive assembly.
Please contact your Agilent service
representative.
4 Defective main board.
