| Note (Contact resistance) | in new state |
| Note (General) | Inductive loads (e.g. contactors, relays, etc.) are to be suppressed by means of a suitable circuit. |
| 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.; Automatic start: The automatic start is programmed by connecting the feedback circuit to the terminals X1/X2. If the feedback circuit is not required, establish a bridge.; The control recognises cross-short, cable break and earth leakages in the monitoring circuit.; 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); In case of a 1-channel control, connect the NC contact to the operating voltage and bridge S11/S12 and S21/S22. |
