Abstract
A safety system for safeguarding a moving, guided motion element against unwanted collisions with an object located on a motion path in the direction of motion of the motion element. The safety system includes an object-detection device for detecting an object in an area of the motion element. The object-detection device can be blocked with respect to object detection by a motion of the motion element, and has an electronic unit with which the motion of the motion element can be controlled and which is configured to assign a blocked state to the object-detection device when the motion element approaches in the blocked state an object or motion element will not trigger a safety mode and when a shut-off signal coming from the motion element is detected, at least part of the object-detection device is transferred into the blocked state.
