2. Motor Stalled
This indicates that the pusher block travel has been
impeded. This may be caused by the tubing plunger
hitting bottom, a kink in the tubing (occlusion), tubing
plunger binding or any situation requiring more force to
the head of the tubing than the pump is capable of
delivering. To restart the pump, remove the cause of
stalling and/or increase the force setting, then press
RUN. The pump will continue the interrupted procedure
where it stopped.
3. Out of Range
A value was entered or encountered in a pump program
that was beyond the pump’s limits.
4. Power Failure Notification
If power to the pump is interrupted during operation, an
alarm will sound to alert the user to the interruption.
When power is restored, an onscreen message is
displayed to indicate the interruption.
5. Unit Won’t Power Up
Verify the the Power Source Switch on the rear of the
pump is set to DC-IN if powering through power supply
or RS-485 if powering in a chain.
