Pusher block makes a snap or click sound when the pump is started: This is a normal condition. When
the pusher block is manually moved, the drive-nut may not have been fully engaged on the drive screw. The
sound heard is the drive-nut engaging on the drive screw.
Pump doesn’t stop after dispensing a set volume: The pump was previously setup with a multiple Phase
Pumping Program. To simply dispense a fixed volume at a fixed pumping rate, the second Program Phase
must be the ‘Stop’ function. See section 7.1, How to Enter Pumping Programs, for instructions on changing the
Pumping Program.
Pump stops pumping after a period of time: A dispense target volume has been set. Verify that the dispense
target volume is set to 0.
