Note (applications)Guard systemSafety sensor

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)Expansion of enable delay time: The enable delay time can be increased from 0.1 s to 1 s by changing the position of a jumper link connection under the cover of the unit.If neither start button nor feedback circuit are connected, a jumper connection must be mounted between X1 and A1.If only one external relay or contactor is used to switch the load, the system can be classified in Control Category 3 to ISO 13849-1, if exclusion of the fault “Failure of the external contactor” can be substantiated and is documented, e.g. by using a reMonitoring 2 guard door(s), each with a magnetic safety sensor of the BNS rangeStart push button: A start push button (NO) can optionally be connected into the feedback circuit. With the guard door closed, the enabling paths are then not closed until the start push button has been operated.The feedback circuit monitors the position of the contactors K3 and K4.The ISD tables (Intergral System Diagnostics) for analysis of the fault indications and their causes are shown in the appendix.The wiring diagram is shown with guard doors closed and in de-energised condition.To secure 2 guard doors up to PL d and Category 3
