2. Completion of the charging process
When the charger completes the charging process the message
of
AVAIL
will appear.
STOP
the charger.
After disconnection the battery will be ready for use.
3. Equalization charge
The start of the equalization charge is indicated by the message
EQUAL. During the equalization charge, the charger displays
the current, the battery voltage, voltage per cell, remaining
time
4. Faults
Fault
Cause
Solution
DF-CUR
Appears before a DF1 fault is dis-
played.
DF1*
Charger problem.
DF1 appears when the charger is not able to supply its output current.
DF2*
Output default.
Check the correct connection of the battery (reversed polarity cables)
and the output fuse.
DF3*
Wrong battery.
Too high or too low battery voltage. Battery voltage must be between
1.6V and 2.4V per cell. Use proper charger for battery.
DF4
Battery discharged more than 80%
of its capacity.
Charge continues.
DF5
Battery requires inspection.
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, temperature,
capacity, cables. Check the battery (defective cells, high temperature,
water level..).
DF PUMP
Fault in the air circuit of the electro-
lyte circulation system.
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 charge.
TH*
Thermal problem in charger resul-
ting in charge interruption.
Verify the proper operation of the fans and/or absence of too high
ambient temperature, or there is poor natural ventilation to the charger.
WATER LEVEL*
Critical battery electrolyte level.
Top up battery electrolyte. Do not fill in until top of the cell in order to
avoid overflow by the next charge.
BAT TEMP*
Critical battery temperature.
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. Control the temperature sensor of the
Wi-iQ

MOD TH
Alternating with charge parameters
- one or more modules in thermal
fault - the charge process continu-
es - the faulty module(s) is (are)
dis red led flashing.
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, a TH* fault will follow.
MOD DFC
Alternating with charge parameters
- one or more module in DF1 fault -
the charge process continues - the
faulty module(s) is (are) displayed
+ red led flashing.
Check power supply.
If all modules are in DF1 fault, a DF1* fault will follow.
DEF ID
Blocking fault - one or more mo-
dule 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.
Use correct module.
Default of balance voltage detected
by the Wi-iQ
Check each battery cell during discharge. Control if the Wi-iQ is
properly adjusted (see Wi-iQ instructions of mounting).
