A light sensing device having background suppression includes: a light transmitter, a light receiver, an evaluation unit for determining the spacing between the light sensing device and an object in a detection zone of the light sensing device, and a setting element for setting a sensing depth within which an object should be detected. A critical spacing region is defined between a set sensing depth and a background in dependence on the set sensing depth. A signal output outputs a signal if an object is detected within the set sensing depth and a display unit displays whether an object is present within the sensing depth. The set sensing depth can be displayed in relation to a maximum sensing depth of the light sensing device in a first display region and a second display region indicates if an object is located in the critical spacing region.

Light sensing device

A safety apparatus has a configurable safety controller () and a configuration means, wherein the safety controller () has at least one input () for the connection of a sensor (-), at least one output () for the connection of an actuator (-), and a control unit () configured to carry out a control program which generates a control signal at the outputs () in a dependence on input signals at the inputs () by means of logic rules. The logic rules are settable by means of the configuration means. A number code representing the logic rules can be generated in the configuration means, and the safety controller () includes an interface () for the input of the number code. The control unit () is configured to carry out a control program with the logic rules represented by the number code.
