Name
1
RJ45
DEIF network Ethernet connection to controller (default connection)
2
RJ45
Ethernet for additional display units
CAUTION
The display unit must be paired to a controller in the DEIF network. During commissioning, or the first time a display unit is
powered, the display unit prompts for a controller confirmation.

13.13.5 Relay output characteristics
Changeover relay, terminals 3,4,5
For future use. You cannot configure this relay.
Status OK relay, terminals 6,7
The relay output on terminals 6,7 is used for the display unit
Status OK
. If the display unit loses communication with the controller, or
an internal failure occurs, then the display unit deactivates the relay.
You cannot change the relay configuration. The relay is always energised when the communication is OK.

13.14 DEIF Ethernet network
13.14.1 Communication
The controllers communicate with each other to manage the system over the DEIF network, an Ethernet network.
For communication redundancy, the controllers can be connected in a ring. If there is a disruption or failure, the DEIF proprietary ring
protocol changes the communication path within 100 milliseconds.
INFO
Controllers must only be connected with
Network chain
or
Network ring
configuration. Do not include display units or other
equipment in the chain or ring.
