A relay with Normally Closed contact is active On
POWER
SERVICE
Pin N°5 (AUX) and internally
connected to Pin N°6 (Exit Pin). The Normally open
contact is connected to input B+ (Pin N°3), so if the
i signal line is not active (engine off) the
appliance will be powered by the leisure battery. When
the engine is running the internal relay will switch on
the AUX and the loads will be powered directly by the
alternator, input B+. The leisure battery will be free of
loads, allowing the
POWER
SERVICE
to further
accelerate the charge while driving.
In case of vehicles without a control unit (self-build
vehicles for example), and/or a vehicle with the
electrical system being installed for the first time, the
AUX input (Pin n°5) will have the same operation
indicated above. It is always advisable to install an
external "split-charge relay", since it guarantees the
recharging of the leisure battery in case of
malfunctions, taking power directly from the alternator.

NOTE
To take advantage of direct charging from the alternator,
the
POWER
SERVICE
switch must be moved to position 0.
The normal position is 1.
