Subject to technical modification without any prior notice.
Cause
Charger or mains
supply 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.
Thermal problem

ting
in

Solution
DF1
appears
when
the charger is not able to
supply
its
output
current.
Follow
the
breakdown
procedure
for the charger, mains
voltage.
Check the correct con-
nection of the battery
(reversed polarity cables)
and the output fuse.
Too high or too low
battery voltage. Battery
voltage must be within
the
acceptable
range.
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
programmed
regulation voltage, or
the charging time is too
long and has exceeded
the safety limit.
Check
charging
para-
meters: profile, tempera-
ture, capacity, cables.
Check the battery (defec-
tive cells, high tempera-
ture, water level..).
Check
the
proper
operation of the pump
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.
Verify
the
proper
operation of the fans
and/or too high ambient
temperature, or wether
there is poor natural ven-
tilation to the charger.
The charge process resu-
mes when the ambient
temperature decreases
below the correct value.
Top up battery electro-
lyte to the level specified
in the battery Instruction
for Use.
Critical

One
or
more
modules are not
working correctly.
One or more mo-
dules are not the
correct
specifica-
tion.

The Wi-iQ on the
battery is not func-
tioning
correctly.
The charger will
charge the battery
with
the
default
setting.
Wait until the battery
temperature cools down,
check the battery state
(water, profile)
Verify
the
set

of
temperature in the menu
Configuration-Battery-

.
Check the temperature
sensor of the Wi-iQ

.
This
fault
will
not
prevent the charger from
operating as long as at
least one module is wor-
king
correctly.
If
all
modules are not working
correctly, the fault code
displayed will be DF1.
It could be due to a mix
of 24/36/48V and 72/80V
modules (not allowed) or
due to an incorrect volta-
ge setting in the charger
menu (eg 72/80V modu-
les with 48V battery set-
ting in the menu)
Battery water topping up
required after charging
or check that the Wi-iQ is
functioning - if in doubt,
contact EnerSys.
Check each battery cell
during discharge.
Check if the Wi-iQ is pro-
perly
adjusted,
if
in
doubt, contact EnerSys.
Verify
the
battery
electrolyte level or the
correct set up of the
charger.
Check the temperature
sensor of the Wi-iQ.
Consult
a
qualified
factory
representative
to conduct preventive
maintenance operation.
Check if the Leds of the
Wi-iQ are flashing, if yes,
try to restart the charge
process, if not or in
doubt contact EnerSys.
