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.

SENSORS AND INSTRUMENTATION FOR MACHINE CONDITION MONITORING
Introduction
The 686-Series Smart Vibration Switch is a low-cost electronic vibration switch designed to monitor vibration
levels on rotating machinery (ie. fans and cooling towers) and trip an alarm or shut down machinery when a
specified vibration limit is exceeded. An onboard accelerometer with precision, microprocessor-controlled
electronics ensures reliable operation and accuracy. The switch contains a two-pin MIL connector for easy drop-
in replacement of mechanical vibration switches and a reliable solid state relay. Multiple units can be installed in a
loop configuration for economical installation and expanded protection of critical machinery. This versatile switch
can be used to replace more expensive electronic vibration switches where separate vibration output is not
required and to replace troublesome mechanical vibration switches.
Every Smart Switch is factory-programmed. See Page 28 for more information.
General Features
Fully USB-programmable from any PC (with optional USB Programmer Kit).
Hermetically-sealed, stainless steel housing for use in corrosive environments.
Imbedded piezoelectric accelerometer for improved accuracy and frequency response.
Small footprint and single ¼-28 stud mounting.
Solid state (AC/DC) relay.
Universal AC or DC power.
Magnetically Adjustable Vibration Threshold (MAVT™).
Connects with industry standard MIL-C-5015 connector or integral cable.
Programmable features
oAlarm threshold level
oNormally Open (NO) or Normally Closed (NC) relay

Operating Principles
The Smart Switch operates over just two wires. It installs in series with any load (ie. annunciator, PLC or relay
coil). To energize itself, the vibration switch scavenges power from the load’s power source. When the alarm
threshold is exceeded, the switch is activated and the load’s power circuit is completed to facilitate the desired
alarm or shutdown.
Figure 1 –Block Diagram
Benefits of Solid State Relays
A solid state relay is an electronic component that functions in the same way as an electromechanical relay, but
without any moving parts. A solid state relay offers the most reliable switch action, especially for vibration
applications where moving relay components run a greater risk of malfunction. They are purely electronic devices
composed of a low current control side and a high current load side for switching action.

Installation
When choosing a mounting method, consider closely the advantages and disadvantages of each technique.
Typical mounting types are stud, direct adhesive, adhesive mounting base and magnetic mounting base.
Note: For a complete list of product specifications, see the “Specification Sheet” and “Outline Drawing” at the end
of this Manual.
Direct Adhesive Mount Procedure
For restrictions of space or for convenience, most sensors (with the exception of integral stud models) can be
adhesive-mounted directly to the machine surface.
Step 1: Prepare a smooth, flat mounting surface. A minimum surface finish of 63 µin (0.0016 mm)
generally works best.
Step 2: Place a small portion of adhesive on the underside of the sensor. Firmly press down on the top of
the assembly to displace any adhesive. Be aware that excessive amounts of adhesive can make sensor
removal difficult.
