DF1*

DF5
DF PUMP
Cause
Charger problem.
Output default.
Wrong battery.
Battery discharged
more than 80% of
its capacity.
Battery requires
inspection.
Fault in the air
circuit of the elec-
trolyte circulation
system.
Solution
DF1 appears when
the charger is not able
to supply its output
current. Follow the
breakdown procedure
for the charger with
control of the IGBT,
diode, mains voltage …
Check the correct
connection of the
battery (reversed
polarity cables) and
the output fuse.
Too high or too low
battery voltage. Battery
voltage must be between
1.6V and 2.4V per cell.
Use proper charger for
battery.
Charge 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 pro grammed
regulation voltage, or
the charging time is too
long and has exceeded
the safety limit.
Check charging
para meters: profile,
tem perature, capacity,
cables.
Check the battery
(defective cells, high
temperature, water
level..).
Check the proper
operation of the pum
via the menu
Option-
Option test.
Check the air circuit
(pump, tubes).
If this fault occurs, the
charger will adapt the
battery charging profile
for an optimised charge.

Too high battery
temperature.
Verify the proper
operation of the fans
and/or absence of too
high ambient tempera-
ture, or wether there is
poor natural ventilation
to the charger.
Top up battery electro -
lyte. Do not fill in until
top of the cell in order
to avoid overflow by
the next charge.
Wait until the battery
temperature cools
down, check the battery
state (water, profile)
Verify the set up of
temperature in the
menu
Configuration-
Battery-High tempera -
ture.
Control the temperature
sensor of the Wi-IQ.
Change of the main
board
Battery water topping
up or ensure that the
Wi-IQ is properly
adjusted and installed
(see Wi-IQ instructions
of mounting)
Check each battery
cell during discharge.
Control if the Wi-IQ
is properly adjusted
(see Wi-IQ instructions
of mounting).
Verify the battery
electrolyte level or the
correct set up of the
charger.
Check the temperature
sensor of the Wi-IQ.
