Notes

Note (General)	Inductive loads (e.g. contactors, relays, etc.) are to be suppressed by means of a suitable circuit.

Circuit example

Note (Wiring diagram)	The control system recognises wire-breakage and earth faults in the monitoring circuit. The example shows a 1-channel control with contact A for a guard door monitor, of which at least one contact has positive break, with external reset button (R). Relay outputs: Suitable for 1 channel control, for increase in capacity or number of contacts by means of contactors or relays with positive-guided contacts. The wiring diagram is shown with non-actuated limit switches and in de-energised condition. (H2) = Feedback circuit
