PCB Piezotronics IMI SENSORS 682 Series User manual

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

SENSORS AND INSTRUMENTATION FOR MACHINE CONDITION MONITORING
Introduction
The 682 Series is a 4-20mA Din Rail Signal Conditioner designed to interface with IMI Sensor’s ICP®
Accelerometer. Acceleration, Velocity, or Displacement can be converted to a 4-20mA signal by simple DIP
Switch selection internal to the Din Rail enclosure. An additional standard feature of the 682 Series is the ability to
convert the temperature output from an accelerometer (when equipped) to 4-20mA. Signal Filtering can be easily
configured in the field by installing factory calibrated Filter Modules into sockets located inside the enclosure.

The 682 Series is designed to be mounted on a 35mm Din Rail. Do not install in a harsh area where it can be
exposed to cleaning fluids or machine oils. IMI Sensors recommends mounting the 682BX3 in a type NEMA 4
enclosure to protect the electronics from contamination.
Dimension Drawing
The Power LED is Green which turns on when the unit is powered. The Fault LED is red which turns on when the
sensor input is either open or shorted. The Acceleration, Velocity, and Displacement LED is Green which turns on
when the corresponding dip switches shown on page 8 are set.

SENSORS AND INSTRUMENTATION FOR MACHINE CONDITION MONITORING
Connector and Pinout Diagram
The 682 Series uses plug-in type screw terminal connectors for all input and output connections.
Strip off 8mm of insulation from the connection wire ends. Using a screwdriver, remove the terminal block from
the enclosure in either the up or down direction, terminate the wire in the correct location. Do not exceed a torque
of 0.5Nm. Re-install the terminal block.
This easy to assemble connection method allows devices to be exchanged easily and the electrical connection to
be visibly isolated.

Filter Module Location
The Filter Modules are utilized to set the cutoff frequency of the internal band pass filter circuit. The 682 Series
comes standard with Modules preinstalled. If a different cutoff frequency is desired, the preinstalled module can
be removed by simply pulling it out of the MOD socket, and replacing it with a different module. The module is
labeled with the type of filter, Low Pass or High Pass, and the cutoff frequency. Module location is as follows:
MOD1: Low Pass (LP) Filter Module Location
MOD2: High Pass (HP) Filter Module Location
Warning: Do not make any adjustments to the internal potentiometers. These potentiometers are used for
factory calibration and adjusting them will require return of the 682 Series unit to the factory for recalibration.

SENSORS AND INSTRUMENTATION FOR MACHINE CONDITION MONITORING
Warning 1 –ESD sensitivity
The power supply/signal conditioner should not be opened by anyone other than qualified service
personnel. This product is intended for use by qualified personnel who recognize shock hazards and are familiar
with the safety precautions required to avoid injury.
Warning 2 –ESD sensitivity
This equipment is designed with user safety in mind; however, the protection provided by the equipment may be
impaired if the equipment is used in a manner not specified by PCB Piezotronics, Inc.
Caution 1 –ESD sensitivity
Cables can kill your equipment. High voltage electrostatic discharge (ESD) can damage electrical devices.
Similar to a capacitor, a cable can hold a charge caused by triboelectric transfer, such as that which occurs in the
following:
Laying on and moving across a rug,
Any movement through air,
The action of rolling out a cable, and/or
Contact with a non-grounded person.
The PCB solution for product safety:
Connect the cables only with the AC power off.
Temporarily “short” the end of the cable before attaching it to any signal input or output.
Caution 2 –ESD sensitivity

PAGE 13
SENSORS AND INSTRUMENTATION FOR MACHINE CONDITION MONITORING
ESD considerations should be made prior to performing any internal adjustments on the equipment. Any
piece of electronic equipment is vulnerable to ESD when opened for adjustments. Internal adjustments should
therefore be done ONLY at an ESD-safe work area. Many products have ESD protection, but the level of
protection may be exceeded by extremely high voltage.
