4.1 Battery functions

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 cut-off (at the battery cut-off switch of the Electrobloc, see Fig.

4, Pos. 15, see also section 3.4) isolates the following connections from the

living area battery:

F all 12 V consumers

F the frost protection valve

This prevents slow discharge of the living area battery by the standby cur-

rent during shutdown of the vehicle (discharge with approx. 4 Ah in month).

The batteries can still be charged using the Electrobloc, the alternator, an

auxiliary charging unit or the solar charge regulator, even when the battery

cut-off switch is switched off.

The switching option provided by the battery selector switch ensures opti-

mum charging of the two battery types, lead gel and lead acid.

The battery monitor of the DT ... control and switch panel constantly moni-

tors the living area battery with dynamic voltage threshold. Lower discharge

currents cut off ”earlier” than with larger currents. This provides improved to-

tal discharge protection. Monitoring is also performed in the switched-off

state. A warning message is displayed below 12.0 V (dependent on current

drain).

If the voltage of the living area battery sinks further, falling below 10.5 V, the

battery monitor immediately switches off all 12 V consumers. The control

and switch panel also switches itself off. Only the frost protection valve con-

tinues to be powered (so it stays closed). Before switch-off, all switch states

and the value of the battery capacity are stored and restored after power-on.

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 12 V supply can begin operation for a short time. In this case

the 12 V main switch on the DT ... control and switch panel must be swit-

ched on.

However , if the battery voltage remains below 11.0 V, the 12 V power supply

can not be turned back on.

Fully charge the living area battery as soon as possible. For more informa-

tion, see the ”Battery voltages” description in the associated DT ... control

and switch panel instruction manual.
