Control of guard locking
If the device is used as guard locking for personnel protection, the control of the guard locking must be regarded as a
safety function.
The device does not feature a safety characteristic for the control of the 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 the control of the guard locking is defined only by the external control (e.g. PFH
D, ext.
for the standstill
monitor).
