Automatic start
If the equalisation charge has been programmed
( Configuration/Equalisation menu), the equalisation charge is initiated
automatically.
If the battery remains connected, and in order to maintain it in a fully
charged condition, refresh charges followed by an equalisation charge
will be automatically initiated according to the battery technology.
Similar indications to those displayed in manual start (see above)
are displayed.

MESSAGES AND FAULT CODES
Fault
Cause
DF1*
Charger problem.
DF2*
Output default.
DF3*
Wrong battery.
DF4
Battery discharged more
than 80% of its capacity.
DF5
Battery requires
inspection.
DF PUMP
Fault in the air circuit
of the electrolyte
circulation system.
TH*
Thermal problem in
charger resulting 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 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 correct charger for
the 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 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 temperature, 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 a safe, optimised
charge.
Verify the correct operation of
the fans, check for too high
ambient temperature, or
whether there is poor natural
ventilation to the charger.
Top up battery electrolyte level
in accordance with 'battery
operating instructions'.
TEMP*
Critical battery
temperature.
DEF EEP*
Memory/Charger menu.
DEF MENU*
DEF CFG* Error in configuration or
1 phase missing
IQ SCAN
Look for present Wi-IQ
IQ LINK

Wi-IQ-Charger
Low electrolyte level
Default of balance voltage
detected by the Wi-IQ
Battery temperature
T
too high.
Preventive maintenance
indicator.
(*): blocking fault preventing charging from continuing.
9
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 .
Control the temperature sensor
of the Wi-IQ.
Change the main board
Check the input fuses and the
3 phases, if OK, enter the pass-
word, go into the configuration
menu, select charge menu,
select charger list and select
the right configuration on the
list.
®
Battery water topping up or
ensure that the Wi-IQ is
properly adjusted and
installed (see Wi-IQ mounting
instructions)
Check each battery cell during
discharge.
Check the Wi-IQ is correctly
set-up (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.
Consult a qualified factory
representative to conduct
preventive maintenance
operation.
