DC-Kit2 with Dometic B1600/Systems with enable input

 Roof air conditioner:
– Dometic B1600, systems with enable input approved by the manufacturer
 Circuit diagram
– Dometic B1600: fig. 4, page 6
 Charging current distributor: ECL-102
 Inverter: PP2002
The light system voltage UD+ is measured. If this voltage exceeds a variable voltage
value Ue (12.5 V – 14.0 V), the relay contact 30/87 (Batt. 2/Batt. 2) of the power relay is
closed. The starter battery and the additional battery are therefore connected in parallel
with low resistance and are charged together by the light system.
NOTE
I
This air conditioner is not linked to the ECL-102 using an on/off cable.
Contact I2, l3 is closed with UD+ > Ue and the inverter thereby switched on if the inverter
remote control is not on "0".
If the light system voltage falls below a variable threshold value Ua (10.5 V – 12.5 V), due
to an increased load because of the air conditioner, relay contact 30/87 (Batt. 2/Batt. 2) is
opened. Relay contact I2, I3, which interrupts the connection between the on/off cable
and the inverter, is also opened.
This switches off the inverter and hence the air conditioner as well. The light system now
charges the starter battery. If the caravan has a connecting cable between the two batteries,
the additional battery is also charged.
If the charging voltage of the light system UD+ reaches the set voltage value Ue again,
the power relay and the control relay switch on again. The air conditioner starts again.
NOTE
I
Other roof air conditioners with enable input: the roof air conditioner will not
switch on again automatically after it has been without voltage.
If the vehicle engine is not switched on (UD+ = 0 V), relay contact 30/87 (Batt. 2/Batt. 2)
is opened and relay contact I2, I3 is closed. The air conditioner can be operated and only
takes power from the additional battery. If the battery voltage falls below Ubatt = 10.5 V,
the inverter switches off.
