Repair and Maintenance
PCB guarantees Total Customer Satisfaction through its
“Lifetime Warranty Plus” on all Platinum Stock Products
sold by PCB and through its limited warranties on all other
PCB Stock, Standard and Special products. Due to the
sophisticated nature of our sensors and associated
instrumentation, field servicing and repair is not
recommended and, if attempted, will void the factory
warranty.
Beyond routine calibration and battery replacements
where applicable, our products require no user
maintenance. Clean electrical connectors, housings, and
mounting surfaces with solutions and techniques that will
not harm the material of construction. Observe caution
when using liquids near devices that are not hermetically
sealed. Such devices should only be wiped with a
dampened cloth—never saturated or submerged.
In the event that equipment becomes damaged or ceases
to operate, our Application Engineers are here to support
your troubleshooting efforts 24 hours a day, 7 days a
week. Call or email with model and serial number as well
as a brief description of the problem.
Calibration
Routine calibration of sensors and associated
instrumentation is necessary to maintain measurement
accuracy. We recommend calibrating on an annual basis,
after exposure to any extreme environmental influence,
or prior to any critical test.
PCB Piezotronics is an ISO-9001 certified company whose
calibration services are accredited by A2LA to ISO/IEC
17025, with full traceability to SI through N.I.S.T. In
addition to our standard calibration services, we also offer
specialized tests, including: sensitivity at elevated or
cryogenic temperatures, phase response, extended high
or low frequency response, extended range, leak testing,
hydrostatic pressure testing, and others. For more
information, contact your local PCB Piezotronics
distributor, sales representative, or factory customer
service representative.
Returning Equipment
If factory repair is required, our representatives will
provide you with a Return Material Authorization (RMA)
number, which we use to reference any information you
have already provided and expedite the repair process.
This number should be clearly marked on the outside of
all returned package(s) and on any packing list(s)
accompanying the shipment.

Introduction
ND INSTRUMENTATION FOR MACHINE CONDITION MONITORING
The Model 685AX8 Series Mechanical Vibration Switches are shock sensitive mechanisms for shutdown of
engine or electric motor powered equipment. These switches use a magnetic latch 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
shutdown the machinery.
General Features
• Designed to Detect Shock/Vibration in 3-Planes of Motion
• Fully Adjustable
• Includes Magnetic Latching Feature
• Accommodates normally open (NO) and normally closed (NC) wiring schemes.
• Manual Reset Button on all models
• Remote Reset option available on 685A18 (350mA @ 24VDC) or 685A28 (350mA @ 115VAC.)
• Designed for use in hazardous locations. (Class I Div 1 Groups C & D)
• Top cover is threaded for easy access to wiring terminals.
