Abstract
A maintenance system for a gate device includes a controller, at least one temperature sensor, and an evaluation unit. The controller has a motor control unit which actuates a drive apparatus for driving a gate member, and a non-volatile memory which stores gate data. The gate data is retrievable from the non-volatile memory. The at least one temperature sensor is arranged in a region of the drive apparatus. The at least one temperature sensor continuously transmits a detected temperature as further gate data to the non-volatile memory of the controller. The evaluation unit creates a temperature curve for each of the at least one temperature sensor over a preset operating cycle. A comparison of more than one temperature curve allows a conclusion to be drawn of a need for maintenance of the gate device.
