Error ID: 22441
During initialization the pump defines the operation position of the pump drives and therefore the pistons. First the pump drive moves backwards to find a mechanical stop within the ball screw. Afterwards, pistons move forwards for finding the maximum available stroke volume. These values are expected within a pre-defined range. "Maximum stroke too short" means that the outer drive position is too close. This can be caused by a drive initialization without pump head or if the pump head has not been installed properly (screws are loose).
Parameter: 1 – 4 referring to pump drive
Probable cause | Suggested actions | |
|---|---|---|
1 | Wiper shifted | Please contact your Agilent service representative. |
2 | Pump head blocks piston movement | Replace, clean or repair pump head. |
3 | Pump drive motor is mechanically blocked. | Please contact your Agilent service representative. |
