Zusammenfassung:A device and method for detecting a misaligned or missing step of a conveyor are disclosed. The missing step detector includes various sensors for detecting the drive speed of the conveyor and for detecting the presence of pallets or steps. The sensor output signals are correlated to determine fixed values characteristic of the specific conveyor in question. Using the fixed values as reference, the missing step detector is able to effectively monitor the conveyor for misaligned or missing steps independent of conveyor speed and time.
