Additional functions
This output can be used to continually supply an existing refrigerator control-
ler.
The power supply to this consumer is automatically interrupted as soon as
the engine starts running (the D+ connection is live in this case or switched
to ground, depending on the type of vehicle). The awning light can still be
used even if the 12V power supply is switched off.
The conventional D+ signal (D+ connection is live when the engine is run-
ning) is evaluated directly.
An integrated D+ converter enables the connection of vehicles for which the
D+ signal is provided as an active ground signal (e.g. FIAT).
A changeover switch on the electroblock specifies which D+ signal is to be
evaluated.
This feature provides an automatic max. 2 A float charge for the starter bat-
tery when the 230V mains is connected to the electroblock.
This output is suitable for supplying the side marker lights of the motorhome.
The associated voltage output is switched on as soon as control signal ”Ve-
hicle lighting ON” of the basic vehicle is applied at the relevant control input
of the EBL 271.
This output provides a supply voltage to operate an electric fold-away bed.
The voltage is only applied when switch AUX ON of the control and switch
panel is ON AND D+ is not applied, i.e. the vehicle engine is not running.
This prevents unintentional operation of the bed whilst the vehicle is moving.
