Input Values
8.3.1. Control Relay Wiring
Up to five control Relays are supplied with the controller. Following the printed lead markings (NO /
Normally Open, NC / Normally Closed, C / Common), users have to ensure that the relay leads on each
of the relays are wired to the correct position on the power supply board.
1. Run the connection cables through conduit openings 3 and 4.
2. Using a screwdriver, connect the cable leads to the appropriate jack connectors and plug them
in the corresponding sockets.
Note:
Wire gauge is load dependent. Users should not exceed relay contact’s rating of
5A/250Vac or 5A/30V DC, resistive load.
8.3.2. Alarm Relay Wiring
The alarm relay provides a contact closure which can be used as a switch to turn an external device
on or off.
Note:
Alarm contacts are form C rated 5A at 250 Vac, 2A at 30 Vdc, resistive load. Fuse
protected: 5A, 250V slow blow fuse.
