The information contained in this document supersedes all similar information that
may be found elsewhere in this manual.
Service –Due to the sophisticated
nature of the sensors and associated
instrumentation provided by PCB
Piezotronics, user servicing or repair is
not recommended and, if attempted,
may void the factory warranty. Routine
maintenance, such as the cleaning of
electrical connectors, housings, and
mounting surfaces with solutions and
techniques that will not harm the
physical material of construction, is
acceptable. Caution should be observed
to ensure that liquids are not permitted
to migrate into devices that are not
hermetically sealed. Such devices
should only be wiped with a dampened
cloth and never submerged or have
liquids poured upon them.
Repair –In the event that equipment
becomes damaged or ceases to
operate, arrangements should be made
to return the equipment to PCB
Piezotronics for repair. User servicing or
repair is not recommended and, if
attempted, may void the factory
warranty.
Calibration –Routine calibration of
sensors and associated instrumentation
is recommended as this helps build
confidence in measurement accuracy
and acquired data. Equipment
calibration cycles are typically
established by the users own quality
regimen. When in doubt about a
calibration cycle, a good “rule of thumb”
is to recalibrate on an annual basis. It is
also good practice to recalibrate after
exposure to any severe temperature
extreme, shock, load, or other
environmental influence, or prior to any
critical test.
PCB Piezotronics maintains an ISO-
9001 certified metrology laboratory and
offers calibration services, which are
accredited by A2LA to ISO/IEC 17025,
with full traceability to SI through
N.I.S.T. In addition to the normally
supplied calibration, special testing is
also available, such as: sensitivity at
elevated or cryogenic temperatures,
phase response, extended high or low
frequency response, extended range,
leak testing, hydrostatic pressure
testing, and others. For information on
standard recalibration services or
special testing, contact your local PCB
Piezotronics distributor, sales
representative, or factory customer
service representative.
Returning Equipment –Following
these procedures will ensure that your
returned materials are handled in the
most expedient manner. Before
returning any equipment to PCB
Piezotronics, contact your local
distributor, sales representative, or
factory customer service representative
to obtain a Return Warranty, Service,
Repair, and Return Policies and
Instructions Materials Authorization
(RMA) Number. This RMA number
should be clearly marked on the outside
of all package(s) and on the packing
Service, Repair, and Return
Policies and Instructions

list(s) accompanying the shipment. A
detailed account of the nature of the
problem(s) being experienced with the
equipment should also be included
inside the package(s) containing any
returned materials.
A Purchase Order, included with the
returned materials, will expedite the
turn-around of serviced equipment. It is
recommended to include authorization
on the Purchase Order for PCB to
proceed with any repairs, as long as
they do not exceed 50% of the
replacement cost of the returned
item(s). PCB will provide a price
quotation or replacement
recommendation for any item whose
repair costs would exceed 50% of
replacement cost, or any item that is not
economically feasible to repair. For
routine calibration services, the
Purchase Order should include
authorization to proceed and return at
current pricing, which can be obtained
from a factory customer service
representative.
Contact Information –International
customers should direct all inquiries to
their local distributor or sales office. A
complete list of distributors and offices
can be found at www.pcb.com.
Customers within the United States may
contact their local sales representative
or a factory customer service
representative. A complete list of sales
representatives can be found at
www.pcb.com. Toll-free telephone
numbers for a factory customer service
representative, in the division
responsible for this product, can be

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

SENSORS AND INSTRUMENTATION FOR MACHINE CONDITION MONITORING
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.
