ELECTRICAL SYSTEM FUNCTIONS

CAR BATTERY (B1) RECHARGING
When the battery charger is charging, an electronic device allows a recharging (max 2A) of the car
battery (B1), the system gives priority to the leisure battery (B2).
LEISURE BATTERY (B2) RECHARGING
a) by alternator: through the separating relais, when the engine is started.
b)
by 230V net: buffer system through battery charger
c)
by solar panel: through solar regulator.
ELECTRONIC BATTERY SEPARATOR
An electronic device controlled by the ignition switches on the batteries parallel when the car battery
voltage is over 13.5V and switches off when engine is off or voltage is lower than 12.5V. This device
operates only if the B2 leisure battery is connected.
This device controls the relays of the users depending from exit simulating +OUT D+ (3 way function
fridge, awning light, antenna motion, etc.).
NB:
in the case of installation of equipment that needs permanent exclusion of the battery parallel relay
(ref. 1), you must remove the R37 resistor (ref. 2). The resistor can be removed using a wire cutter,
being careful not to damage the PCB traces below.
