Note (General)Inductive loads (e.g. contactors, relays, etc.) are to be suppressed by means of a suitable circuit.
Wiring example
Note (Wiring diagram)Automatic start: The automatic start is programmed by connecting the feedback circuit to the terminals S12/X3. If the feedback circuit is not required, establish a bridge.Input level: The example shows a 2-channel control of a guard door monitoring with two position switches, whereof one with positive break, external reset button (R); cross-wire monitoring and feedback circuit (H2)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.The wiring diagram is shown with guard doors closed and in de-energised condition.
