Wiring 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. | 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. | To secure 3 guard doors up to PL d and Category 3 | Monitoring 3 guard door(s), each with a magnetic safety sensor of the BNS range | The feedback circuit monitors the position of the contactors K3 and K4. | Start 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. | If neither start button nor feedback circuit are connected, a jumper connection must be mounted between X1 and S13. | 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 reliable down-rated contactor. A second contactor leads to an increase in the level of security by redundant switching to switch the load off.
