ABSTRACT:
For controlling and surveying the operation of elevator systems pulse generators are used which are integrated into antifriction bearings of mutually pivotable structural members of the elevator system. By measuring pulse numbers and pulse frequency, conditions of movement and positions of moving parts, like e.g. the elevator cage (5) and the doors (13), can be detected and evaluated in a computer.
