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. The control system recognises wire-breakage and earth faults in the monitoring circuit. 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. For 1-channel control, connect NC contact to S11/S12 and bridge S12/S22 Connect potential p-type outputs of safety light grids/curtains to S12/S22. The devices must have the same reference potential. 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) |
