Error ID: 2041, 2042
Motor-Drive Power: Pump channel A
B: Motor-Drive Power: Pump channel B
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 | 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 | Flow path blockage in front of the pressure sensor. | Ensure the capillaries and frits between the pump head and pressure sensor inlet are free from blockage. |
3 | Blocked (passive or active) inlet valve. | Exchange the (passive or active) inlet valve. |
4 | Blocked outlet valve. | Exchange the outlet valve. |
5 | High friction (partial mechanical blockage) in the pump drive assembly. | |
6 | Defective pump drive assembly. | Please contact your Agilent service representative. |
7 | Defective mainboard. | Please contact your Agilent service representative. |
8 | Restriction capillary blocked at pre-mixing union. | Exchange restriction capillary. |
