The concept of the charging process is explained
based on a 12 V battery.
Diagnosis
Diagnostic function which automatically checks the
battery status and recognises the voltage.
Voltage Function
0 V bis 1.5 V "Error" LED (9) lit. Battery defective.
1.5 V bis 12 V Charging starts.
12 V bis 13 V Maintenance charging starts.
14.6 V Battery fully charged. "Full" LED
(10) lit.
>15 V "Error" LED (9) lit.
Step 1: Condition check
The charger checks the battery condition and calcu-
lates the required
charging parameters.
Step 2: Desulphation (rescue)
•
The charger can rescue most drained batteries
with voltages up to a minimum of 1.5 ±0.5 V.
•
The safety switch does not allow the charger to
start charging if the voltage is below 1.5 ± 0.5 V.
•
At a voltage range of 1.5 ± 0.5 V to 10.5 ± 0.5 V
the charger will initiate pulse charging.
•
If the voltage rises above 10.5 ± 0.5 V, the charger
will switch to the previously selected regular
charging mode, which will charge faster and more
safely.

Step 3: Precharging
The battery is gently charged with a low charging
current to return the battery to a chargeable state.
Step 4: Soft start
The battery is gently charged with a low charging
current.
Step 5: Base charge with a constant current
The battery is quickly and safely charged with a
consistent current.
Step 6: Base charge with a constant voltage
The battery is charged at a constant charge end
voltage until it is fully charged.
Step 7: Analysis
Once the battery is fully charged, the charging
process will stop.
Step 8: Equalisation charge
If the battery is fully charged and drops to 12.8V
within 2 minutes, another charging process will
begin automatically.
Step 9: Maintenance charging
The charger monitors the battery capacity. Once
the battery falls below 12.8 V, the charger will emit a
charging pulse. This maintains the battery's highest
possible charging level.
SAFETy
FUNcTIONS
The charger features the following safety features
to prevent damage to the charger and the battery
or the vehicle:
•
Short circuit (defective battery),
•
incorrect connection (connected with reversed
polarity),
•
sparking
•
overheating
•
excess current
•
