4. Completion of charging with Float
If the float function has been selected the screen will show
The message floating:
•
During equalization
•
Line 1. mode floating
•
Current / voltage per cell
5. Completion of charging without equalization
The green 'charging complete' light is illuminated and
the message AVAIL is displayed. The display shows, in alter-
nation:
•
The charging time taken.
•
Non-blocking faults if present
•
The number of Ah recharged

Appears before a DF1 fault is displayed.
DF1*
Charger fault.
DF2*
Charger fault.
Unsuitable battery.
DF3*
The battery has been discharged more
DF4
than 80% of its capacity.
DF5
Battery requires inspection.
DF7
Pneumatic mixing air circuit fault (the
red light flashes).
TH*
Thermal fault resulting in interruption of
charging.
MOD TH
Alternating with charge parameters -
one or more modules in thermal fault -
the charge process continues - the faulty
module(s) is (are) displayed + red led
flashing.
MOD DFC
Alternating with charge parameters -
one or more modules in DF1 fault - the
charge process continues - the faulty
module(s) is (are) displayed + red led
flashing.
DEF ID
Blocking fault - one or more modules
are not compatible with the charger
configuration (for example 24V charger
with one 48V module). This can happen
if the user replaces one module with
another one with a different voltage
setting.
(*) A blocking fault preventing charging from continuing.

Remedial action
Check the power supply and the input fuse(s).
Check the power supply voltage.
Check that the battery is correctly connected (that the cables are
not reversed) and check the output fuse.
Battery voltage too high or too low. Connect the correct battery
to the charger.
Charging continues.
DF5 appears when the charging profile has been achieved with
a fault condition, that can be a current increase in regulation phase
demonstrating a battery heating or a badly programmed regulation
voltage, or the charging time is too long and has exceeded the
safety limit. Check charging parameters (profile, temperature,
capacity, cables). Check the battery (defective cells, high tempe-
rature, water level).
Check the air circuit (pump, tubing).
Check that the fan(s) is (are) working correctly and/or that the
ambient temperature is not too high or whether there is poor
natural ventilation to the charger.
Check that the fan(s) is (are) working correctly and/or that the
ambient temperature is not too high or whether there is poor
natural ventilation to the charger.
If all modules are in thermal fault then a TH* fault will follow.
Check power supply.
If all modules are in DF1 fault then a DF1* fault will follow.
Use correct module.
