Process and device for monitoring objects

摘要

Described are a process and a device for monitoring objects, such as tools or process areas. A feeler pin (34) can be pivoted by means of an electric motor (20) in both directions of rotation, starting from a zero position, so that two objects or process areas can be monitored. The zero position of the feeler pin (34) is determined by means of the microcomputer in a teach-in cycle, starting from the desired angular value of a reference stop.
