Product Information M800 Elite Speed Switch M800 Elite Speed Switch Monitors Rotating Machinery for Dangerous Underspeed Conditions APPLICATION The M800 Elite Speed Switch is designed to detect belt slip, belt underspeed, stop motion, low speed or zero speed on bucket elevators, conveyors, airlocks, mixers, fans, grinders and many other rotating machines. Totally sealed and simple to calibrate, the M800 Elite works in the harshest of conditions. METHOD OF OPERATION An inductive sensing device located in the nose of the M800 Elite enclosure will detect a metal target. This target can be an existing bolt head or device attached to a shaft. During installation the M800 Elite is set to the normal machine shaft RPM by calibrating with the magnet provided. The internal microprocessor sets the alarm and shutdown relays. Two M800 Elite models are available: Model M8001V10C may be used either as a dual trip unit with 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 with 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. If required, the M800 Elite has an additional pulsed output, which can be connected to display actual shaft RPM on a PLC or speed display.
