ELECTRICAL SYSTEM FUNCTIONS
a) alternator: Throught engine
b) : Throught 240V mains power
Operation without SMART ALTERNATOR:
When the battery charger is charging, an electronic
device allows a recharging ( A) of
the c battery (B1), the system gives priority to
the leisure battery (B2).

through separate relays when engine is on.
The ignition electronically controls the relays:
parallel, fride, awning light etc.
An electronic device controlled by the “+ key” ON
switches on the D+ functions (batteries parallel, OUT
D+ simulated output, awning light etc.) when the car
battery voltage is > 13.5V and switches them off with
the “+ key” OFF or with voltage < 12.5V.
D+ FUNCTIONS
CHASSIS BATTERY (B1) RECHARGING
mains power throught battery charger.
The D+ functions can be activated only if the B2
leisure battery is connected.
LEISURE BATTERY (B2) RECHARGING
c) solar panel: through solar
regulator.
Throught charge
Condition B: with “+ key” ON signal and “D+”
negative signal (-). The functions are
deactivated in absence of one of
those two signals.

:
Condition A: with “+ key” ON signal and car battery
voltage > 13,5V. The functions are
deactivated with “+ key” OFF or with
voltage < 12,5V.
For vehicles equipped with SMART ALTERNATOR
n electronic device switches on the D+ functions
(batteries parallel, OUT D+ simulated output, awning
light etc.) when the engine is running. The D+
functions are activated in presence of at least one of
following conditions:
,
a
The D+ functions can be activated only if the B2
leisure battery is connected.
N.B.: In presence of both conditions, the functions
are deactivated in absence of the “+ key” signal.
IMPORTANT in the case of installation of equipment that needs permanent exclusion of the battery parallel
relay (ref. 1), you must remove the R resistor (ref. 2). The resistor can be removed using a wire cutter,
being careful not to damage the PCB traces below.
