Abstract
A safety system for detecting the presence of an undesired object in a safety area may include a first pair of distance measuring sensors disposed on opposed sides of the conveying path, the pair of distance measuring sensors defining a sensor field between said pair of distance measuring sensors, and an electronic control device operatively coupled to the sensors. The electronic control device may be configured to initiate a machine-stopping sequence based at least in part on signals received from the distance measuring sensors.
