In an emergency, it must be possible to unlock the escape release from the hazard area/from the machine side without any additional equipment. The device must be manually operated and it is essential that it acts on the barrier. Activating the release must lead to a permanent locking of the guard lock (see also mechanical release).
The emergency unlocking is designed to unlock a guard lock in an emergency. The unlocking can be carried out from the access side/outside without any tools. During emergency unlocking, the switch engages in the unlocked position and a procedure similar to a repair will be required be reset to its original position.
