Driving mode: power supply from the 12 V battery with motor
switched on
In driving mode, the starter and supply battery are electrically connected
when the light system is active. This means the supply battery can be
charged from the light system.
Starter batteries may not be discharged as much as supply batteries. To pre-
serve the starter battery, the charging current distributor separates the starter
battery from the supply battery, if the charging voltage in the starter battery
drops below 10.5 V. This also ensures that the starter battery is charged
before the supply battery.

If the charging voltage regulator cuts the connection to the supply battery
due to low voltage, it switches off the roof air conditioner at the same
time. The inverter remains active and has voltage in its socket.
As soon as the voltage in supply battery has reached the switch-on point
in the charging current distributor, the roof air conditioner switches on
again.
If the voltage in the supply battery drops further and goes below the
10.5 V switch-off point for the inverter, the inverter switches off (chapter
"Driving mode: power supply from the 12 V battery with motor
switched off" on page 30).

If the charging voltage regulator cuts the connection to the supply battery
due to low voltage, it switches off the inverter at the same time using the
MCR-9 remote control. There is no voltage in the socket for the inverter.
As soon as the voltage in the supply battery reaches the switch-on point
in the charging current distributor, it restores the connection between the
starter and supply battery and switches the inverter on again using the
MCR-9 remote control. There is voltage in the socket again for the
inverter.
The air conditioning starts again automatically.
If the voltage in the supply battery drops further and goes below the
10.5 V switch-off point for the inverter, the inverter switches off (chapter
"Driving mode: power supply from the 12 V battery with motor
switched off" on page 30).
