PRODUCT OVERVIEW
The M800 Elite Speed Switch is designed to detect belt slip, belt underspeed, stop motion, low speed or
zero speed on bucket elevators, conveyors or rotating machinery. The unit requires no contact with the
shaft, is fully solid state, and has a virtually unlimited operating life. Two models are available:
Model M8001V10C may be used either as a dual trip unit giving an alarm at 10% below set speed and a
shutdown signal at 20% below set speed, or a single trip giving a shutdown signal at 20%.
Model M8002V10C may be used either as a dual trip unit giving an alarm at 5% below set speed and a
shutdown signal at 10% below set speed, or a single trip giving a shutdown signal at 10%.
A simple calibration facility allows either model to be programmed to give a start up delay of up to 15
seconds, while simultaneously calibrating for normal running speed. An auxiliary pulse output is provided
which can be connected to display actual shaft RPM on a PLC or speed display.
