Wiring example

Note (Wiring diagram)

The wiring diagram is shown with guard doors closed and in de-energised condition.

Relay outputs: Suitable for 2 channel control, for increase in capacity or number of contacts by means of contactors or relays with positive-guided contacts.

The control recognises cross-short, cable break and earth leakages in the monitoring circuit.

2 channel control shown for a guard-door monitor with two contacts, of which at least one contact has positive break, with external reset button (R).
