4.2.2 RAG Node Interfaces: Power and Comms (PL4)
The main physical interface to the RAG node is via the Bypass to Node ribbon cable. This cable can
only be connected one way.
Assuming an operational system, once the Bypass cable is pushed into place, the Node will be
provided with power and data.
Assuming correct configuration at the controller, the Node may begin operation immediately.
4.2.3 RAG Node Interfaces: LED signals
SK1 – 4 are used for the LED signal interfaces. For basic RAG installations;
•
RED is connected to SK4
•
Amber is connected to SK3
•
Green is connected to SK2 (also referred to as Green1)
If there is a requirement for a second filter (Second Green);
•
Extra Green must be connected to SK1 (also referred to as Green2).
