Introduction The Mechanical Vibration Switch is a shock sensitive mechanism for shutdown of engine or electric motor powered equipment. This switch uses a patented linear adjustment magnetic latch technology to ensure reliable operation. Pushing the reset button moves the tripping latch into a magnetically held position. A shock/vibration will move the magnet beyond this holding position, thus freeing the spring loaded tripping latch to transfer the contacts and shut down the machinery.
Installation: The vibration switch is sensitive to shock and vibration in all three planes of motion – up/down, front/back and side/side. Side/side (in the same plane as the reset pushbutton) is the most sensitive. For maximum sensitivity, mount the unit so that the side with the reset button is in-line with the direction of rotation of the machine. The vibration switch must be firmly attached/mounted to the machine so that all mounting surfaces are in rigid contact with the mounting surface of the machine.
Chassis Screw Terminal Remote Reset and Power On Delay Models EX685A19, EX685A29 and EX685A39 have provisions to reset the switch remotely. The vibration switch can be remotely reset after being tripped by applying the correct voltage across the reset terminal as shown below.
NOTE: If using the solenoid for a power on delay, do not exceed the “on” times listed. If the “on” time exceeds 4 minutes and/or the “off” time is shortened before energizing the solenoid again, the solenoid will be permanently damaged.
