Automatically selected modes:

5.2 Pulse Charging

This is an automatic function of the charger and
cannot be selected manually. If the battery voltage
at the start of the charging process is between 8V
(± 0.5V) and 10.5V (± 0.5V) in the 12V mode, the
charger operates automatically in the pulse charging
mode. On attaining a battery voltage above 10.5V
(± 0.5V), the unit continues to charge the battery
in the charging mode selected. This enhances the
charging process and ensures a better condition of
the battery.

5.3 Trickle Charging

The charger switches automatically to this mode
when the battery is fully charged. In this mode,
a small current is delivered to the battery when
necessary to keep the full charge.
Automotive Aftermarket
The charger can be left connected to the battery of
a vehicle when it is not being used (ie. convertible,
motorcycle, classic car, etc.). The charger will
monitor the battery and keep it at a high charging
level without risk of damage.

5.4 Charger Protection Function

Appliance Protection Function
The charger switches to standby mode in the
following abnormal situations.
• Remaining battery voltage < 6V (12V batteries)
• Open circuit
- no battery or only one pole is connected to
the charger
• Reverse polarity
- the DC cables from the charger are
incorrectly connected to the battery
In the event of reverse polarity, the LED (9) will light
up. If no other setting is chosen, the system remains
in standby mode.
In the event of a short, the cable fuse (4a) will
protect the unit and the electrical system from
damage.
Overheating Protection
If the unit becomes excessively hot during charging,
the output power is automatically reduced to avoid
damage to the charger.
