ABSTRACT:
In an electrically powered machine subject to occasional blockage, the speed, power consumption, torque and/or rate of deceleration are displayed by successive illumination of light-emitting diodes in a row. Predetermined limit values for these parameters alone or summed with one another are defined and optical couplers are positioned at corresponding locations on the row to detect parameters reaching the limits. Detection causes initiation of disconnection, braking, reversal or other means for alleviating the stoppage.
