Dc-Kit3 With Dometic Freshjet1100/1700/2200 - Dometic Waeco ECL-76 Instructions De Montage Et De Service

Technical description
I
NOTE
The system is not connected to the ECL-102 using an on/off cable. The D+ sig-
nal is run via the relay contact I2 onto I5 and connected to the remote control.
Contact I2/I5 is opened with UD+ > Ue and this switches the air conditioner on.
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. The relay contact I2/I5 is closed and switches the inverter off
via the remote control.
The air conditioner is therefore without voltage and does not work. The light system charg-
es 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 relay contact I2/I5 is opened
and switches the inverter on again. The CA1000 and CA2500 can be switched on by the
operator again; the B1600 restarts automatically.
If the vehicle engine is not switched on (UD+ = 0 V) relay contact 30/87 (Batt. 2/Batt. 2)
and relay contact I2/I5 are opened. 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 in-
verter switches off.

DC-Kit3 with Dometic FreshJet1100/1700/2200

 Roof air conditioner: Dometic FreshJet1100/1700/2200
 Circuit diagram: fig. a, page 13
 Charging current distributor: ECL-102
 Inverter: SinePower MSI1812T
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.
Contact I2/I5 is opened with UD+ > Ue. This switches on the air conditioner.
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. The relay contact I2/I5 is closed and switches the air conditioner compressor off.
The light system now charges the starter battery (the fans consume little power). 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 compressor
starts again.
