3. Description of the safety function
Devices from this series feature the following safety functions:
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 6.8. Switching states on page 9 ):
-The safety outputs are switched off when guard locking is released (monitoring of the locking element).
-The safety outputs are switched off when the guard is open (monitoring of the door position).
-The guard locking can be activated only if the handle module is located in the switch head (prevention of inadvertent
locking position (faulty closure protection)).
Ì Safety characteristics: category, Performance Level, PFH
D
(see chapter 14. Technical data on page 30 ).
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 solenoid 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 defined only by the external control (e.g. PFH
D, ext.
for the standstill monitor).
