Wiring example

Note (Wiring diagram)
The wiring diagram is shown with guard doors closed and in de-energised condition. | Automatic start: The automatic start is programmed by connecting the feedback circuit to the terminals X1/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) and feedback circuit (H2). | The control recognises cross-short, cable break and earth leakages in the monitoring circuit. | 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. | The safety enabling circuit 37/38 conforms to EN 60204-1 for STOP Category 1. The safety enabling circuits 13/14 and 23/24 conform to EN 60204-1 for STOP Category 0. | F1 = Hybrid fuse
