4.2 Operating principle
4.2.1 Overview
Protective doors are frequently used to fence off danger zones. These are monitored for
position and, if necessary, the area from which the hazard emanates is switched off. If the
machine continues to present a hazard even after switching off, access can be prevented for
this period by a tumbler. An emergency stop command device is additionally monitored for
shutting down the machine in an emergency. CM AS-i Master and F-CM AS-i Safety are used
to connect to the fail-safe controller.
