Abstract (en)

[origin: DE19754141A1] The invention relates to a device for monitoring functional units on escalators and moving walkways, comprising several processors which monitor predetermined parameters of a particular functional unit independently of each other. At the same time, the processors independently monitor the driving motor for the steps/pallets and/or the driving motor for the hand rail(s), especially the speed(s) of said driving motor(s). The processors are connected to safety contacts for immediately shutting down the escalator or moving walkway and interact with at least one other processor which is provided for controlling and/or diagnosing functions which are not relevant to safety.
