Abstract

A device and method for automatically adjusting safety control parameters of a conveyor are disclosed. The safety device may include various sensors and a safety control module. The safety control module may be preprogrammed with a learn-run method configured to learn operational and mechanical characteristics of a conveyor, validate the operational characteristics of the conveyor based on predefined nominal specifications, and determine a safety function with calibrated safety control parameters by which to monitor conveyor operation.
