Resolution:
The status of the Safety Guard Lock is monitored by the Safety function.
This means you can use a normal button or PLC output to unlock the safeguard, because of the  Safety Guard Lock monitoring the  safety controller.   XPSMCWIN will stop the machine automatically when unlocking the Guard and also block the restart of the machine before the Guard is locked again.  See image below.



If you have potentially dangerous machine with high inertia (long rundown time).  The guard is interlocked (by a solenoid for example); it cannot be opened until the machine is standstill

In that case, you will to prevent the safety guard unlocking when the machine is running.

This can be acheived by wiring a zero speed monitoring relay contact in series to the unlock push button which block command, when the machine is not in standstill.
