Application
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.

Operating principle
The position of a protective door is monitored via two position switches. When the monitored door is opened, the modular safety system trips and switches the motor starter off safely. The motor starter then safely shuts down the load. If the door is closed and the feedback circuit is closed, the Start button can be used to switch on again.

Note
This example applies to configurations within a control cabinet. If the logic components and the actuators are not located in the same control cabinet, other precautions must be taken, such as cross-circuit-proof laying of the shutdown signal.
