ELECTRICAL SYSTEM FUNCTIONS

CHASSIS BATTERY (B1) RECHARGING
When the battery charger is charging, an electronic
device allows a recharging (
the c hassis battery (B1), the system gives priority to
the leisure battery (B2).
LEISURE BATTERY (B2) RECHARGING
a) Throught engine alternator:
through separate relays when engine is on.
The ignition electronically controls the relays:
parallel, fride, awning light etc.
b) Throught 240V mains power
mains power throught battery charger.
c) Throught solar panel: through solar
regulator.
D+ FUNCTIONS
Operation without SMART ALTERNATOR:
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.
The D+ functions can be activated only if the B2
leisure battery is connected.
IMPORTANT in the case of installation of equipment that needs permanent exclusion of the battery parallel
relay (ref. 1), you must remove the R
being careful not to damage the PCB traces below.

Operation with SMART ALTERNATOR (present on
all DS 520 distribution boxes manufactured since
September 2019)
For vehicles equipped with SMART ALTERNATOR
a 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:
Condition A: with "+ key" ON signal and car battery
voltage > 13,5V. The functions are
deactivated with "+ key" OFF or with
voltage < 12,5V.
Condition B: with "+ key" ON signal and "D+"
negative signal (-). The functions are
deactivated in absence of one of
those two signals.
N.B.: In presence of both conditions, the functions
are deactivated in absence of the "+ key" signal.
The D+ functions can be activated only if the B2
leisure battery is connected.
