4.2 Connecting a Bus Line
If several units are being operated (max 31) in one
coldroom, the remote control will be connected to the left
socket (plug with pins), and the right-hand socket will
be used to make the bus connection to the next unit. The
other plug of the bus connector is plugged into the left
socket of the next unit. The blind plug will be inserted into
the right socket of the last unit.
The addressing of the individual units will be done
automatically in the order they are connected to the bus.
If a unit is to be switched off it is removed from the bus,
and the addresses of the following units are reduced
automatically by one.
The power supply for the remote control is supplied by
the first unit. If the power for this unit is switched off, the
next unit takes over.
5.
Drainage of defrost condensation
The refrigeration units have an integrated condensation
water pan with overflow safety.
In case of high condensation, it may be necessary to
provide an additional condensation drain. The 12mm
plugs for this are on the side of the condenser, on the
right side of the unit.
6.
Coldroom electrical power supply
There is a 4-pin socket on the refrigeration unit on the
suction side of the evaporator for the electrical power
supply of devices in the coldroom with a total power
supply of 250 Watt (lighting, door frame heating). This
socket can also be used for a door contact switch.
