Point-interlock testing device for point regulator, has processing device to generate testing signal to indicate overshooting of permissible value of variation of detected sliding distance covered by sliding component

摘要

The device has a sliding component pushed to adjust a point-interlock of an adjustable point blade. A sensor (38) detects a sliding distance covered by the sliding component, where the distance is compared with a reference sliding distance. A processing device (42) generates a testing signal to indicate the overshooting of a permissible value of variation of the detected distance with respect to the reference distance.
