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

SENSORS AND INSTRUMENTATION FOR MACHINE CONDITION MONITORING
Introduction
Models 691C41 and 691C42 are rotary switch boxes that provide terminal strip inputs for sensor cable termination
with the convenience of BNC & military connectors for switched outputs and terminal strips for continuous
outputs. They are typically used in conjunction with third-party data collectors and analyzers. The boxes provide
simultaneous vibration and temperature inputs on every channel so that they can be used in conjunction to
temperature output (TO) sensors (accelerometers with a built-in temperature sensor that provide simultaneous
vibration and temperature signals). Specifications and drawings are below for reference:

Installation
Establish an easily accessible location for
installation.
Fiberglass rotary switch boxes include four
polyester mounting brackets and four stainless
steel attachment screws that are shipped loose to
facilitate enclosure mounting. There are
positioning indents on the back of the box in each
corner. Once the mounting brackets are
positioned properly, they should then be fastened
to the box with the provided screws. Hardware for
fastening the mounting brackets to the installation surface are to be
provided in the field.
Painted steel and stainless steel boxes include two factory-installed
mounting brackets on the top and bottom of the box. Hardware for
fastening the mounting brackets to the installation surface are to be provided in the field.
Box may or may not have shipped from factory with factory-installed connection ports. If box did ship from factory
with factory-installed connection ports, ensure that box is mounted with connection ports facing down. The
factory-installed connection port options are listed in the table below.

SENSORS AND INSTRUMENTATION FOR MACHINE CONDITION MONITORING
If the box did not ship from factory with factory-installed connections ports, drill/punch the necessary holes in the
bottom of box for the input and output cabling. Be very careful when drilling/punching holes in the box as to not
damage the internal metal, terminal strips and printed circuit boards. Also, take every possible precaution to
prevent water entrainment into the box.
Grounding the Enclosure
To ground the internal shielding system (ground planes on PC Board, mounting panel and switch enclosure), an
external earth ground wire must be connected. To do this, the bottom, right, inner-mounting hole has a double
nut included. Unscrew the nut and insert ground wire between the washers and screw nut tightly down again.
This will earth ground all the shields and the inner metal pieces. This will not ground the (-) input of the vibration
sensors, since they are isolated from the shield.
Input Wiring
Sensor cables should be routed through connection ports and then connected to their respective channel’s
terminal strip per the diagram below. If connection ports are cord grips, cord grips should then be tightened to
maintain the enclosure’s ingress protection rating.

Output Wiring
Using the Enclosure
When collecting data from the enclosure using the BNC and/or MIL connectors and a data collector, connect the
data’s collector connector to its appropriate connector mate in the box and modulate the switch to the appropriate
channel. If the output terminals are not being used, then the data collector must provide power for the sensor in
order to for a signal to be obtained. If the output terminals are being used, then the sensor is already being
powered and the data collector does not need to provide power.
Calibrating the Enclosure
The models do not require calibration. If there are any questions concerning the products, please contact the
factory.

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.
