Pump drive error
Error ID: 29212, 29213
The pump drive failed during calibration.
• Parameter: 1 – 2 referring to pump drive
Maximum stroke is too short
Error ID: 29203
The maximum stroke is too short.
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).
