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).
