Inductive loads (e.g. contactors, relays, etc.) are to be suppressed by means of a suitable circuit.
 
notice - Wiring example
 
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).
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.
(H2) = Feedback circuit
The control recognises cross-short, cable break and earth leakages in the monitoring circuit.
The wiring diagram is shown with guard doors closed and in de-energised condition.
