5 Functions
5.1 Battery charge functions
Simultaneous charging of the starter battery and the leisure battery by the alternator, parallel
connection of the batteries via a cut-off relay.
There is also simultaneous charging of the starter battery and leisure battery (up to 18A in
total) for a connection to the 230V supply. The switch ensures optimal charging of the lead-
acid and AGM battery types.
If a solar regulator is connected to the EBL 252, together with a solar panel, the two batte-
ries are charged automatically given sufficient sunshine.
5.2 Additional functions
This relay supplies the AES/compressor refrigerator with power from the starter battery
when the vehicle engine is running and the D+ connection is live. An AES refrigerator is also
powered by the leisure battery when the vehicle engine is not running.
CAUTION!
The ”AES / Compressor refrigerator” fuse (see Fig. 2, Pos. 11) may only be used when the
refrigerator installed in the vehicle is a compressor refrigerator. If it is deployed when using
an absorber refrigerator, the leisure battery is discharged within a short period.
The power supply of this consumer is interrupted automatically as soon as the engine is run-
ning. The awning light can still be used even if the 12V supply is switched off.
The power supply of this consumer is automatically switched on as soon as the engine is
running. Provided the engine is running, this means an additional electric heater can be ope-
rated for the vehicle. The output is enabled instead of the output for the awning light, and
hence has common fusing together with the awning light.
The power supply for the water pump is switched on and off by a switching stage in the
EBL 252 electroblock via the operator and control panel connected.
6Faults
A flat battery or defective fuse is the cause of most f aults in the 12V system.
