12 Volt Outputs - Calira EVS 38/20-DS/IU Mode D'emploi

' &
If it is not possible to reach the D+ control contact of the generator, an
automatic switch is integrated in the device, which establishes and separates the
parallel connection of the two batteries as a function of the voltage of the
starter battery.
Mains operation
(all voltage values with respect to a battery temperature of 20 °C)
When connecting to the mains of 230 volt, the supply battery is charged first.
Once the supply battery reaches a voltage of 14.3 volt, it is switched in parallel
with the starter battery. If the charging current rises to its rated value due to a
user and the battery voltage falls below 13.2 volt, then the parallel connection
is automatically disconnected. The starter battery thus always remains ready to
start.
Solar operation
When connecting external solar cells, the starter battery is also charged
provided that the voltage of the supply battery has reached 14.3 volt. If the
voltage of the supply battery drops below 13.2 volt, the parallel circuit is
disconnected again.

12 volt outputs

User circuit 1 (lower wiring loom A01 Pin 1) and
User circuit 2 (upper wiring loom A02 Pin 2)
The outputs to the users only carry +12 volt if the bistable user relay has
switched on. The user relay only switches on if +12 volt control voltage is
applied to pin no. 4 of the 12-pole plug. The user circuits are each protected by
a 10 A fuse.
Permanent current for heating and immediate light (A01 pin 4)
Heating and immediate light are supplied independently of the user relay. They
are connected to the permanent positive and protected with a 7.5 A fuse.
Water pump (A01 pin 3)
When the main switch on the control board is switched on and the water pump
switch is in the ON position, the fresh water pump will be supplied by the
water pump relay. The control voltage for the water pump relay is connected to
pin 7 of the 12 pole plug. The circuit for the water pump is protected with a
5 A fuse on the unit.
Refrigerator
Changeover switch to position Absorber (A01 pin 5)
