Possible causes
The battery pack can no
longer operate the unit.
There is system level fault.
The pump nipple, inlet barrel,
water barrier, exhaust (inside
pump cradle), or sample
tubing is blocked.
The unit is not properly
seated in the charger or the
battery is alkaline and cannot
be charged.
The battery temperature is
outside the allowable tem-
perature range for charging.
Recommended actions
Charge or replace the battery pack.
See an on-site supervisor or contact ISC Tech-
nical Support (see "Contact Information").
Check for debris at the pump nipple, inside the
inlet barrel, at the water barrier, inside the pump
cradle, and in the tubing. Attempt to clear any
blockage.
If the condition persists, the filter or the tubing
may need to be replaced.
Remove the pump from the charger. Re-dock a
Li-ion powered pump.
Allow the battery to reach a temperature that is
within the allowable range for charging.
