Battery monitoring
The battery monitoring in the transformer/rectifier monitors the voltage in the
living area battery.
If the battery voltage falls below 10.5 V, the battery monitor in the transformer/
rectifier switches off all of the 12-V appliances, excluding the safety/drainage
valve.
Measures:
Switch off all the electrical appliances that are not essential at the corre-
sponding switch.
If necessary, use the 12 V main switch to switch the 12 V power supply
back on briefly. This is only possible, however, if the battery voltage lies
above 11 V. If the voltage is below this level, the 12-V power supply cannot
be switched on again until the living area battery has been recharged.
9.3.3
Charging the battery
When the vehicle engine is running, the vehicle alternator recharges the living
area battery and the starter battery. When the vehicle engine is switched off,
the batteries are automatically disconnected from one another by a relay in the
transformer/rectifier. This prevents the starter battery from being run down by
electrical appliances in the living area. The starting capability of the vehicle is
thus preserved. The charging condition of the living area battery or the starter
battery can be read on the panel.
If the vehicle is connected to the 230 V power supply, the living area battery
and the starter battery are automatically charged by the charger module on the
transformer/rectifier. The starter battery is charged with a float charge of 2 A.
The charging current is adapted to suit the charging condition of the battery.
This ensures that it is not possible to overload the battery.
To make use of the maximum output from the charger module on the trans-
former/rectifier, switch off all electrical appliances during charging.
