specific aux connection (pin no. 5) for the following
models: Plus 25, plus 30, Plus 40, plus 24-24 / 20, Gold 25-m,
gold 30-m, gold 40-m, gold 24-24-m.
powerservice has an auxiliary terminal: (terminal n°5) dedicated
to the original control unit output (eg CBE, SARGENT, Schaudt,
nord elettronica) or to the split-charge relay. THIS TERMINAL IS
USED TO CONNECT APPLIANCES SUCH AS THE FRIDGE, LIGHTS, PUMP, ETC.
ALL THE CABLES THAT WERE ORIGINALLY CONNECTED TO THE LEISURE
BATTERY'S POSITIVE TERMINAL SHOULD BE CONNECTED TO THIS AUXILARY
INPUT (5).
a relay with Normally Closed contact is active On 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 ignition+ signal
line is not active (engine off) the appliance will be powered by
the service 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 service battery will be
free of loads, allowing the powerservice 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 service battery in case of malfunctions,
TAKING POWER DIRECTLY FROM THE ALTERNATOR.
Note: to take advantage of direct charging from the
alternator, the powerservice switch must be moved to
POSITION O. THE NORMAL POSITION IS 1.
