Electronic Vibration Cutout Switch (Optional)
Two models of electronic vibration cutout switches are available. The single set point
model contains one trip limit for shutdown. The dual set point model contains two
independent trip limits; one for alarm and one for shutdown. The shutdown set-point is
factory set at
0.45 in/sec. Additional details can be found in the submittal packet.
Testing:
• The test position sets in the minimum set point so that any vibration will cause a trip
condition.
• The light will come on immediately, and the trip will occur after the duration of the
time delay, proving the complete system is operational.
• If test position is maintained for less than the duration of the time delay, the trip will
not occur, thus permitting the system test without shutdown.
Calibration:
• A light adjacent to the set point control comes on the instant the measured vibration
level exceeds the set point.
• The unit can be periodically calibrated on line by turning the set point control down
until the light comes on. This setting is then compared with the vibration measured
with a portable vibration meter, thus providing a calibration check of the unit.
• If the trip setting is maintained, trip will occur after the duration of the time delay.
Remote Reset:
Connection of between terminals 5 and 6 latches triac output in alarm
state after set point is exceeded. Opening the connection will reset the output to non-
alarm state.
