Automatic battery recognition

As soon as the charger is connected to the mains
power supply, the LED display
lights up.
The charger recognises the battery on the basis of
the following criteria:
If the voltage of the battery is less than 3.8 V or
greater than 15 V, the battery is not suitable for
charging or defective. In this case, the LED Dis-
plays , ,
charger remains in "Standby mode" and cannot be
switched to another charging mode by means of
the MODE selection button

Pulse charging mode

The mode is suitable for the charging/regeneration
of empty, used and overcharged 12 V lead-acid
batteries.
When the charger is connected to a battery and
the charging process starts it automatically rec-
ognises the battery voltage. It will switch to pulse
charging mode if the voltage is in the range of
7.5 V ± 0.5 to 10.5 V ± 0.5 V.
This pulse charging process is continued until the
battery voltage has increased to 10.5 V ± 0.5 V.
As soon as this state is reached, the charger switch-
es over to the previously selected normal charging
mode.
Now the battery can be charged quickly and safe-
ly. Most empty, used or overcharged batteries can
be regenerated and reused using this procedure.
NOTE
► During the pulse charging process, the LED
display flashes.

Trickle charging

The charge is equipped with an automatic trickle
charging function. Depending on the voltage of the
battery, the charger reacts by supplying different
charging current. The battery can remain connect-
ed to the charger for a long period of time.

Protective function of the appliance

In the case of an incident such as short circuiting, a
critical voltage drop during the charging process,
an open circuit or reversed connection of the output
terminals, the charger deactivates the electronic
system and immediately switches back to its basic
state to avoid damage.
If you do not activate any settings, the system will
remain in Standby mode. If the terminals are incor-
rectly connected (reverse polarity), the LED display
"ERROR" also lights up.
If the appliance becomes too hot during charging,
the power output is automatically reduced. This
also protects the appliance from damage.

Maintenance and cleaning

WARNING! Always remove the
power plug from the wall socket
before carrying out any work on
the battery charger.
The appliance is maintenance-free.
♦ Under no circumstances should solvents or other
aggressive cleaning agents be used.
♦ Clean the plastic surfaces of the appliance with
a soft, dry cloth.
