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.
