Pump Error Messages
Motor-Drive Power
Error ID: 2041, 2042
The current drawn by the pump motor exceeded the maximum limit.
Blockages in the flow path are usually detected by the pressure sensor in the
damper, which result in the pump switching off when the upper pressure limit
is exceeded. If a blockage occurs before the damper, the pressure increase
cannot be detected by the pressure sensor and the module will continue to
pump. As pressure increases, the pump drive draws more current. When the
current reaches the maximum limit, the module is switched off, and the error
message is generated.
Probable cause Suggested actions
1 Damper disconnected.
Please contact your Agilent service
representative.
2 Defective damper.
Please contact your Agilent service
representative.
3 Defective main board.
Please contact your Agilent service
representative.
Probable cause Suggested actions
1 Flow path blockage in front of the damper.
Ensure the capillaries and frits between the
pump head and damper inlet are free from
blockage.
2 Blocked (passive or active) inlet valve.
Exchange the (passive or active) inlet valve.
3 Blocked outlet valve.
Exchange the outlet valve.
4 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.
