When connecting to the mains, the supply battery is charged first. Once the
supply battery reaches a voltage of 14 V, it is switched in parallel with the
starter battery. The power supply only activates the timer once both batteries
have reached a voltage of 14.4 V. If the supply voltage of the battery drops
again below 13 V, the parallel circuit is automatically disconnected. The starter
battery thus always remains ready to start.
When connecting external solar cells, the starter battery is also charged
provided that the supply voltage of the battery has reached 14 V. If the supply
voltage of the battery drops again below 13 V, the parallel circuit is
disconnected.
The outputs to the consumers (1 to 3) only carry +12 V if the consumer relay
has switched on. The consumer relay only switches on if + 12 V control voltage
is applied to contact no. 4 of the 7-pole plug. Consumer circuits 1 and 2 are
each protected with a 10 A fuse, and consumer circuit 3 is protected with a 15 A
fuse.
Heating and immediate light are supplied independently of the consumer relay.
They are connected to the permanent positive and protected with a 7.5 A fuse.
The fresh water pump is also supplied via the consumer relay. It is protected
with a 5 A fuse. This circuit is regulated from the control panel via contact no. 7
of the 7-pole plug.
Changeover switch in position A ==> absorber operation
When the engine is running, the refrigerator is supplied with power via the
generator of the vehicle. After the engine is switched off, the refrigerator relay
disconnects the refrigerator from the supply battery. The control action is via the
cable from the D+ of the generator. Thus, operating the refrigerator at 12 V is
only possible during journeys. When the vehicle is parked, the refrigerator can
only be run on gas or mains voltage. This prevents the supply battery running
down. This circuit is protected by a 15 A fuse.
