3. Description of the safety function
Devices from this series feature the following safety functions:
3.1. With active guard lock monitoring
Monitoring of guard locking and the position of the guard
(interlocking device with guard locking according to ENISO14119)
Ì Safety function (see chapter 6. Function on page 10):
- The safety outputs are switched off when guard locking is released (monitoring of the locking element).
Important: This applies only if guard lock monitoring is active!
- The safety outputs are switched off when the guard is open (monitoring of the door position).
Ì The safety functions are ensured only if the actuator is mounted properly (see chapter 8. Mounting on page 15).
Ì Safety characteristics: category, Performance Level, PFH
D
(see chapter 16. Technical data on page 40).
The following additionally applies in a BR series connection:
Ì The safety outputs are switched on only when the device receives a corresponding signal from its predecessor in the chain.
NOTICE
You can regard the complete BR device chain as one subsystem during calculation. The following
calculation method applies to the PFH

for calculation.
Control of guard locking
If the device is used as guard locking for personnel protection, control of guard locking must be regarded as a
safety function.
The device does not feature a safety characteristic for control of guard locking, because the guard locking sole-
noid is completely disconnected from outside the device (no control function within the device). It therefore does
not contribute to the failure probability.
The safety level for control of guard locking is dened only by the external control (e.g. PFH
D, ext.
for the standstill
monitor).
