Electromagnetic compatibility (EMC) EMC rating EMC-Directive Status indication Indicated operating states Position relay K2 Position relay K1 Internal operating voltage Ui Position relay K3/K4 Other data Note (applications) Safety sensor Guard system Emergency-Stop button Pull-wire emergency stop switches Safety light curtain Note Note (General) Inductive loads (e.g. contactors, relays, etc.) are to be suppressed by means of a suitable circuit. 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
