Low Low Pump has sensed battery current present, but the
battery gauge on the battery pack is not commu-
nicating. Check connections from main board, to
interconnect, to battery pack.

– High Normal alarm message. Software uses position po -
tentiometer to monitor motion of the plunger driver
during delivery. If the motion is not correct this
alarm is generated.
May be caused because pump was not primed and
clutches took too long to engage, or may occur when
user squeezes the plunger lever and moves plunger
head.
May also occur if position pot is not calibrated or is
contaminated – use Biomed > Utilities and run
View Alarm History
to check if failure occurs at
same position reading.
