MPRC Speed Display
The MPRC speed display is used to indicate the speed of the step band of an escalator. By measuring the rotational speed of the escalator drive while taking the gear ratio into account, the current speed is shown in m/s. The MPRC receives its speed information from the cams mounted on the flywheel of the escalator motor. With the aid of inductive proximity switches, pulses are generated that serve to monitor the rotational speed of the escalator. The pulses generated are first fed to the RC3 speed monitor for speed monitoring in accordance with EN115.
