Battery functions

4.1
6-cell lead acid or lead gel batteries, 55 Ah and above
Simultaneous charging of the starter battery and the living area battery via
the alternator, parallel connection of the batteries via a cut-off relay
The battery is isolated with the battery cut-off switch.
This prevents the living area battery from slowly discharging due to closed
circuit current while the vehicle is not in use.
With the switching option with the battery selector switch, the optimal char-
ging of the two types of batteries, lead-gel and lead -acid, is guaranteed (ap-
prox. 5 -- 20mA)
With control and switch panel: approx. 5 -- 20mA
(depending on the control and switch panel used) under the following condi-
tions:

The battery monitor compares the current of the living area battery to a refe-
rence current. As soon as the battery current drops below 10.5V, all 12V
consumers are switched off via main switch relays 1 and 2.
Only the frost protection valve continues to be powered.
The automatic disconnector is not triggered by short-term low voltage (shor-
ter than 2 seconds), caused by high current when switching on consumers.
If an overload or an insufficiently charged living area battery causes the vol-
tage to fall so low that the automatic disconnector is triggered, any non-es-
sential consumers should be switched off.
If need be, the 12V supply can begin operation for a short time. For this,
switch on the 12V main switch on the control and switch panel.
However, if the battery current remains below 11.0V, the 12V supply can not
be switched on again. Fully charge the living area battery as soon as possi-
ble. For more information, see the description of "battery voltages".
