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 (21) 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
(19) lit�
>15 V "error" leD (21) 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�
12 V 24 V
•
The safety switch does not allow the charger to
start charging if the voltage is below 1�5 ± 0�5 V�
20 A 60 A 30 A
•
at a voltage range of 1�5 ± 0�5 V to 10�5 ± 0�5 V
the charger will initiate pulse charging�
0�5 - -
•
If the voltage rises above 10�5 ± 0�5 V, the charger
will switch to the previously selected regular
1�5 - 1
charging mode, which will charge faster and more

Step 3: Precharging
9 3 6 The battery is gently charged with a low charging
current to return the battery to a chargeable state�

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�
6 7 8 9
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�
