Note (Wiring diagram)
For 2-channel control with cross-wire monitoring, connect the NC contact to S11/S12 and S31/S32 and bridge S21/S22 | F2 = Fuse for signalling outputs | The ISD tables (Intergral System Diagnostics) for analysis of the fault indications and their causes are shown in the appendix. | The control recognises cross-short, cable break and earth leakages 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. | "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" swit | F1 = Hybrid fuse | 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 1-channel control, connect NC contact to S11/S12 and bridge S21/S22 and S31/S32 | Connect potential p-type outputs of safety light grids/curtains to S12/S22. The devices must have the same reference potential. | The wiring diagram is shown with guard doors closed and in de-energised condition.
