Module Error Messages
Temperature Out of Range
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.
Remove the pump-head assembly. Ensure there
is no mechanical blockage of the pump-head
assembly or pump drive assembly.
2 Partial blockage of the flowpath in front of
the damper.
Ensure the outlet valve is not blocked.
3 Defective pump drive assembly.
