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 termination boxes for triaxial ICP® accelerometers (Models 691M156 and 691M157) provide terminal strip
inputs with the convenience of 4-pin bayonet connector outputs. They are used in conjunction with commercially
available data collectors and analyzers. A few specifications are listed below for easy reference.
Specifications
691M56............................................................................ 1 Channel
691M57.......................................................................... 2 Channels
Input Connectors....................................... 4-Socket Terminal Strip
Output Connector(s) ..................................................4-Pin Bayonet
Enclosure Type.......................................................NEMA 4X [IP67]
Size..................................4.72 x 3.14 x 2.16 in [120 x 80 x 55 mm]
Weight......................................................................0.72 lbs [327 g]
Installation
Establish an easily accessible location for installation, keeping in mind the cabling will be coming from the bottom
panel of the enclosure. Use the supplied mounting feet and hardware to install the unit.
Note: The unit has one or two 4-pin Bayonet connector(s) that can be easily contaminated. Install the unit away
from sprays, cleaning fluids, steam, excess temperature (above 212  F) and other contaminants. Always leave
the dust cap on the connector when not taking data. This will protect the contacts. Do not use the unit outdoors
unless it is protected from the environment.

Wiring
Remove outer cover of the enclosure by loosening the four screws located in each corner of the front panel. Strip
cables back approximately 1/8” to 3/16”. Note the length of the conductor as not to short any neighboring cables.
Feed cables through cable grips.
To connect cable, push down on the top spring-loaded terminal strip connector with a flat head screwdriver. Push
the conductor into the connector front and then remove the screwdriver. This will clamp the cable conductor onto
the terminal strip. Pull gently on the conductor to make sure that it was installed correctly. Tighten the cable
clamp nut located on the outside of the enclosure. This will hold the cable jacket and also protect the internal
connections from environmental contaminants.

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
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.

Warranty
IMI instrumentation is warranted against defective material and workmanship for 1 year unless otherwise
expressly specified. Damage to instruments caused by incorrect power or misapplication, is not covered by
warranty. If there are any questions regarding power, intended application, or general usage, please consult with
your local sales contact or distributor. Batteries and other expendable hardware items are not covered by
warranty.
Service
Because of the sophisticated nature of IMI instrumentation, field repair is typically NOT recommended and may
void any warranty. If factory service is required, return the instrumentation according to the “Return Procedure”
stated below. A repair and/or replacement quotation will be provided prior to servicing at no charge. Before
returning the unit, please consult a factory IMI applications engineer concerning the situation as certain problems
can often be corrected with simple on-site procedures.
Return Procedure
To expedite returned instrumentation, contact a factory IMI applications engineer for a RETURN MATERIAL
AUTHORIZATION (RMA) NUMBER. Please have information available such as model and serial number. Also,
to insure efficient service, provide a written description of the symptoms and problems with the equipment to a
local sales representative or distributor, or contact IMI if none are located in your area.
Customers outside the U.S. should consult their local IMI distributor for information on returning equipment. For
exceptions, please contact the International Sales department at IMI to request shipping instructions and an RMA.
For assistance, please call [phone], or fax us at [phone]. You may also receive assistance via e-
