Circuit example

Note (Wiring diagram)	The wiring diagram is shown with guard doors closed and in de-energised condition. The ISD tables (Intergral System Diagnostics) for analysis of the fault indications and their causes are shown in the appendix. 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. Connect potential p-type outputs of safety light grids/curtains to S12/S22. The devices must have the same reference potential. 2 channel control shown for a guard-door monitor with two contacts, of which at least one contact has positive break, with external reset button (R) and feedback circuit (H2). (example without cross-wire monitoring) For 2-channel control with cross-wire monitoring, connect the NC contact to S11/S12 and S31/S32 and bridge S21/S22 For 1-channel control, connect NC contact to S11/S12 and bridge S21/S22 and S31/S32 'Start function / Reset button: The function 'trailing edge' is programmed by means of the 'AF' switch located underneath the housing cover (switch position = 1). The automatic start is programmed by bridging terminals X3/X5 and by switching the 'AF' switch to 0. The time offset between the channels is approx. 100 ms. An endless time offset between the channels 1 and 2 is programmed by bridging the terminals X3/X6.' F1 = Hybrid fuse F2 = Fuse for signalling outputs
