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, including an object-detection device that includes a plurality of parts for detecting an object in an area of the motion element, wherein the object-detection device can be blocked with respect to object detection by a motion of the motion element, and an electronic unit that controls the motion of the motion element and is configured to assign a blocked state to the object-detection device when the motion element approaches, wherein in the blocked state an object and motion element does not trigger a safety mode, and wherein shut-off means are provided which, when a shut-off signal coming from the motion element is detected, transfer one or more parts of the object-detection device into the blocked state.
