Fault
Critical
Cause
Solution
DF1
Yes
Low output current
Check input voltage and fuses.
DF2
Yes
Output fault
Check for proper battery connection
(reversed polarity). Check output fuse.
DF3
Yes
Incorrect battery
Battery voltage too high (>2.4 Vpc) or
too low (<1.6 Vpc). Use proper
charger for battery.
DF4
No
The battery has been
discharged more than
80% of its capacity.
Prevent future over discharging of
battery. Battery charge gauges and lift
interrupts may need calibration.
DF5
No
Battery requires inspection
Non critical fault. Check battery cables
for condition and size, check for loose
connections, check for defective cells.
Check for defective cells.
DF7
No
Inspect battery
Non critical fault. This will cause the
charge to terminate early. Battery may
require service.
Check the battery (Temperature,
Specific gravity...).
