Detects under-speed conditions in conveyor lines, machine tools,
ventilating systems, or any other rotating shaft where a minimum speed
requirement exists. Typically, a “flat”, keyway, or bolt-head, is detected,
precisely timed, and compared during each revolution to a set-point
adjustment made at “minimum” speed. Any drop in speed immediately
produces an output which may be used for emergency stop or other
control function. The Motion Detectors operate as AC or DC switches
and are available with high- and low-speed ranges.
Use of these protective devices in many applications throughout a plant
can save many times their cost in reduced downtime and equipment
repairs.

A single or multiple targets may be used (even
numbers are recommended to maintain
mechanical balance). The more targets, the
faster the response to an underspeed condition.
The number of targets is limited by the maximum
operating frequency stated in Specifications.

Power-Up
Setpoint adjustment: A 25 turn
potentiometer is used to set the speed
threshold (pulses per minute) to the
normal operating speed. The output
circuit will remain closed unless the
speed falls below the setpoint at which
time it will open. At power up, a 9 second
delay overrides under-speed detection to
allow the equipment to reach normal
operating speed.
