Abstract
A safety or security light grid for monitoring a protected field having a light transmitting strip, which has a row of light transmitters arranged alongside each other, and a light receiving strip, which has light receivers arranged alongside each other associated with respective light transmitters, so that a plurality of parallel light barriers form the protected field. There is at least one control and evaluation unit, which controls and evaluates the individual light barriers for generating a warning signal when one or more light barriers are interrupted by an object. The light grid has two input elements and at least one display element for configuring the light grid.
