Abstract
A method and a system have at least one sensor for monitoring a plurality of protected zones for infringement by at least one object. A controller controls a plant to be safeguarded having a mechanically movable part, having the sensor for the at least planar monitoring of the protected zones by a control and evaluation unit for evaluating. The received signals of the sensor determine which of the protected zones has been infringed by the object and which protected zone the object has left. The controller generates and outputs a switch signal that is a release signal for the release of the plant operation. The mechanically movable part is either in a first working zone or in a second working zone, with the first working zone and the second working zone each being associated with a first protected zone and a second protected zone, respectively.
