Completion of charging
1. The LCD screen will give you the message of availability
(AVAIL)
The battery is charged and ready to use.
2. STOP the charge and disconnect the battery.
To stop the charge press the Stop/Start button.
Never disconnect the battery during charge without stopping
the charging process.
This could lead to dangerous sparks or charger damage.
3. Completion of charging with equalization
Manual equalization only concerns vented lead/acid batteries.
It will be initiated manually or automatically by switch. All
other technologies will have an automatic preset equalization
time.
To force manual equalization keep pressed the equalization
button (right button) and click the On/Off (only charging
proles for ooded). If automatic then the screen will also
show the following message:
4. Completion of charging with Float
If the oat function has been selected the screen will show
the message oating:
5. Completion of charging without equalization
The green ‘charging complete’ light is illuminated and
the message AVAIL is displayed. The display shows, in
alternation:
• During equalization
• Line 1. mode oating
• Current / voltage per cell
Fault Cause Remedial action
No display and
Blue LED off
No mains supply. Check the power supply and the input fuse(s).
DF CURRENT
Appears before a DF1 fault is displayed.
DF1*
Charger fault. DF1 appears when the charger is not able to supply its output
current. Check the power supply voltage.
DF2*
Charger fault. Check the correct connection of the battery (reversed polarity
cables) and check the output fuse.
DF3*
Unsuitable battery. Battery voltage too high or too low. Battery voltage must be
between 1.6V and 2.4V per cell. Use proper charger for battery.
DF4
The battery has been discharged more
than 80% of its capacity.
Charging continues.
DF5
Battery requires inspection. Charging prole 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 parameters: prole,
temperature, capacity, cables. Check the battery (defective cells,
high temperature, water level, terminals).
DF7
Pneumatic mixing air circuit fault (the
red light ashes).
Check the proper operation of the pump via the menu Option-
Option test. Check the air circuit (pump, tubes).
TH*
Thermal fault resulting in interruption of
charging.
Check that the fans are working correctly and/or that the ambient
temperature is not too high or whether there is poor natural ven-
tilation to the charger.
MOD TH
Alternating with charge parameters -
one or more module in thermal fault
- the charge process continues - the
faulty modules are displayed + red led
ashing.
Check that the fans are working correctly and/or that the ambient
temperature is not too high or whether there is poor natural ven-
tilation to the charger.
If all modules are in thermal fault then a TH* fault will follow.
MOD DFC
Alternating with charge parameters - one
or more module in DF1 fault - the charge
process continues - the faulty modules
are displayed + red led ashing.
Check power supply.
If all modules are in DF1 fault then a DF1* fault will follow.
DEF ID
Blocking fault - one or more module
are not compatible with the charger
conguration (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.
