Error diagnosis for a lift assembly and its components using a sensor

摘要

The lift system has a sensor (8) for detecting the vibrations that are generated in the operation of the lift system. An evaluation circuit (9) is connected with the sensor for evaluating the vibrations detected by the sensor. The detected vibrations are compared with a predetermined operating value and a predetermined threshold value by the evaluation circuit. A quality value is calculated from the comparison of the vibrations with the operating value and with the threshold value by the evaluation circuit. An independent claim is included for a method for operating a lift system.
