Other data
| Note (applications) | Safety sensor Guard system |
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. Monitoring 2 guard door(s), each with a magnetic safety sensor of the BNS range To secure a guard door up to PL d and Category 3 If one or two external relays or contactors are used to switch the load, the system can then only be classified in Category 3 to EN ISO 13849-1, if exclusion of the fault “Failure of the external contactors” can be substantiated and is documented, e.g. by using reliable down-rated contactors. A second contactor leads to an increase in the level of security by redundant switching to switch the load off. The ISD tables (Intergral System Diagnostics) for analysis of the fault indications and their causes are shown in the appendix. |
