Pump stalls and is unable to turn: This may be because the pumping rate is set too high. Reduce rate.
Peristaltic tubing being used may be too rigid for this pump. Replace tubing.
Liquid may be too viscous or there may be too much pressure on the system.
There may be too much tubing in the pump head, reduce distance between tie-raps and recalibrate pump,
refer to section 4.2.1.
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 11.1, How to Enter Pumping Programs, for instructions on
changing the Pumping Program.
Pump stops pumping after a period of time: A dispense volume has been set. Verify that the dispense
volume is set to 0.
