FAULT CODES

Cause
Low output current
Output fault
Improper battery
The battery has been
discharged more than 80%
of its capacity
Battery requires inspection
Inspect battery
Charger overheating
Alternating with charge
parameters – one or more
module in thermal fault – the
charge process continues –
the fault module(s) is(are)
displayed + red led flashing.

Solution
Check input voltage and fuses. Call
for service.
Check for proper battery connection
(reversed polarity). Check output fuse.
Call for service.
Battery voltage too high (>2.4 Vpc) or
too low (<1.6 Vpc). Use proper
charger for battery.
Prevent future over discharging of
battery. Battery charge gauges and lift
interrupts may need calibration.
Non critical fault. Check battery cables
for condition and size, check for loose
connections, check for defective cells.
Non critical fault. This will cause the
charge to terminate early. Battery may
require service.
Check the battery (temperature,
specific gravity...).
Check the battery condition of use.
Check the configuration in the menu
(charge cables parameters).
Check that fans are working. Verify
that ambient temperature is not too
high. Inspect to see if charger
ventilation is obstructed or impaired.
Check that the fan(s) is(are) working
correctly and/or that the ambient
temperature is not too high or or
whether there is poor natural
ventilation to the charger. If all
modules are in thermal fault a TH fault
will follow.
