Patent ID: 8575538

Claim:
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 comprising: an object-detection device for detecting an object in an area of the motion element, which 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 is controlled and which is configured to assign a blocked state to the object-detection device when the motion element approaches, in which blocked state an object or motion element does not trigger a safety mode, wherein shut-off means are provided which, when a shut-off signal coming from the motion element is detected, transfer at least part of the object-detection device into the blocked state, wherein the shut-off means comprise a transmitting element for a shut-off signal which is tuned to a reflector for electromagnetic radiation on the motion element in such a way that a signal of the transmitting element is received by a receiver of the shut-off means only in a predefined motion area of the reflector on the motion element, and whereby at least one of said object-detection device and the shut-off means is a distance sensor.
