Mounting and wiring - continued
2. Connect LON communication network
The installation of the data communication must comply with
the requirements set out in document RC8AC.
3. Connect supply voltage
Is 24 V, and the supply must not be used by other controllers or
devices. The terminals must not be earthed.
4. Follow light-emitting diodes
When the supply voltage is connected the controller will go
through an internal check. The controller will be ready in just
under one minute when the light-emitting diode ”Status” starts
ashing slowly.
5. When there is a network
Set the address and activate the Service Pin.
When the controller is set correct on the network the LED "sta-
tus" will ash quickly for 10 minutes.
6. The controller is now ready to be congured.

Internal communication
between the modules:
Quick ash = error
Constantly On = error
Status on output 1-8
Slow ash = OK
Quick ash = answer from gateway
in 10 min. after network
installation
Constantly ON = error
Constantly OFF = error
Flash = active alarm/not cancelled
Constant ON = Active alarm/cancelled
External communication
Network installation
The connections for the example can be seen
here.
The screen on the pressure transmitter
cables must only be connected at the
end of the controller.
Warning
Keep signal cables separate from
cables with high voltage.
