8.5.3 Battery monitor
The battery monitor 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 the 12 V appliances. The battery cut-off switch is
tripped.
Measures:
„
Switch off all electrical appliances that are not absolutely essential at the
corresponding switch.
„
If necessary, use the 12 V main switch to switch the 12 V power supply
back on for a short while. This is only possible, however, when the battery
voltage is 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.
8.5.4 Charging the battery
When the vehicle engine is running, a relay in the transformer/rectifier alter-
nator switches on the living area battery and the starter battery together and
recharges them with the vehicle generator. When the vehicle engine is
switched off, the batteries are automatically disconnected from one another
again by 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 terminal voltage 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 only charged with a float charge.
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.
