DEVICE FOR MECHANICALLY AND ELECTRICALLY MONITORING THE ADJUSTMENT DRIVE OF POINTS MOTORS

摘要

The invention relates to a device for monitoring the function of devices (4) for adjusting movable points elements (2, 3), in which the movable points elements (2, 3) are interlinked via a coupling rod (13). Said coupling rod (13) comprises rod parts (14, 15) that can be displaced relative to each oth er in the axial direction. The device is further provided with sensors (34, 35) for detecting at least two different positions of displacement of the coupli ng rod parts (14, 15).
