Abstract:
1. Process for monitoring the functioning and/or adjustment of an optoelectronic sensor arrangement exhibiting at least two optical transmitters, to each of which an optical receiver is assigned, such that each optical receiver is designed as a laterally-resolving optical receiver and such that each of the optical transmitters and the corresponding optical receivers are so positioned relative to each other that light beams emitted from the optical transmitter can be detected by the corresponding optical receiver after being reflected by a boundary surface, which process involves the following steps: a) storing a maximum permissible distance between the optoelectronic sensor arrangement and the boundary surface, as determined by recording an object recorded at a plurality of defined distances from the optoelectronic sensor arrangement by at least two light beams, b) detecting current position-proportional reception values for each optical transmitter and corresponding optical receiver, c) determining current relative positions for reception values of any two adjacent optical transmitters, and d) comparing the current relative positions for the reception values with stored reference values for the relative positions.
