MESSAGES AND FAULT CODES

Fault Cause
DF1*
Charger or mains
supply problem.
DF2*
Output default.

Wrong battery.
DF4
Battery discharged
more than 80% of
its capacity.
DF5
Battery requires
inspection.
DF PUMP
Fault in the air
circuit of the elec-
trolyte circulation
system.

Thermal problem
in charger resul-
ting in charge
interruption.
STOP*
Critical battery
electrolyte level

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.
BAT
TEMP*
Critical battery
temperature.
DF MOD
One or
modules are not
working correctly.
WRG
MOD*
One or more mo-
dules are not the
correct specifica-
tion.

NO
Wi-iQ
The Wi-iQ on the
battery is not func-
tioning correctly.
The charger will
charge the battery
with the default
setting.
(*) : blocking fault preventing charging from continuing.
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 temperature.
Check the temperature
sensor of the Wi-iQ
more This fault will
prevent the charger from
operating as long as at
least one module is wor-
king correctly. If
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)
link
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,
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.
