Control system for controlling movement of media has level modifier controlled by main controller to change threshold level stored in comparison controllers for sensor signal comparison

摘要

The control system has a main controller (1) and one or more individual controllers (20), each connected to one or more sensors (S) and each with a sensor signal selector, a comparison controller for comparing sensor signals with stored thresholds, a controller for converting the comparison result into a serial signal and transmitting it to the main controller and a level modifier controlled by the main controller that changes the level stored in the comparison controller.
