3.  Description of the safety function

Devices from this series feature the following safety functions:

Monitoring of the guard position  

(interlocking device with guard locking according to EN ISO 14119)

 

Ì

Safety function (see chapter 

6.4. Switching states on page 10

): 

 -The safety outputs are switched off when the guard is open (monitoring of the door position).

 -The following additionally applies in a BR series connection: the safety outputs are switched on only when the device 

receives a corresponding signal from its predecessor in the chain. 

 

Ì

Safety characteristics: category, Performance Level, PFH

D

 (see chapter 

16. Technical data on page 32

).

NOTICE

You can regard the complete BR device chain as one subsystem during calculation. The following 

calculation method applies to the PFH
