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.

Installation and Wiring
The 684A1/684A4 Enclosure is designed for use in conjunction with the Series 683A Panel Meter/Controller. The
Enclosure can be located near the machine that needs monitoring. Depending on the Enclosure’s configuration,
up to 8 sensors can be connected to the internal terminal blocks for interface to the Panel Meters/Controllers. The
terminal blocks also provide for output connections including Raw Vibration, 4-20mA Retransmit, and Alarm/Alert
Relays.
Establish an easily accessible location for installation and keep in mind where the cabling will be oriented. Once
the unit has been mounted, begin making appropriate connections for the interface cables.
All user connections are made to the terminal blocks (Fig.1) attached to the inside rear panels of the unit through
cord grips located on the bottom of the enclosure. The larges cord grip on the Enclosure should be used for
power connection, all other cord grips are used for sensor and signal interface.
Observe the labels on the terminal blocks when making connections. These labels identify the Panel
Meter/Controller interface where #1 is the TOP ROW LEFT METER, #2 is the TOP ROW RIGHT METER, #3 is
the SECOND ROW FROM TOP LEFT METER, and so on. Each Sensor Input has three connections, which are
made on the terminal strip; one for the signal/power (typically red wire, +), another for ground (typically black
wire), and the third is for the shield (typically a drain wire, SHIELD GND).
Panel Meter/Controller Power is connected to the respective terminal block located in the lower middle position.
Line, Neutral, and Earth Ground are connected to this block. Earth Ground should also be connected to the spade
lugs located on the two bottom screws that hold the terminal block mounting bracket.
The output connections from the terminal blocks consist of Raw Vibration, 4-20mA Retransmit, Alert (typically
SP1) and Alarm (typically SP2) Relays. All of these connections should go to process control/monitoring
equipment, additional signal conditioners, and machine diagnostic tools.
To install the wires, unscrew the terminal block so that enough room exists to insert a wire stripped of its
insulation. Insure that no bare wire is exposed and tighten the screw on the terminal block to hold the wire in
place.
To install Earth Ground to the spade lugs, remove the lugs by first unscrewing the terminal block mounting
bracket. Insert the Earth Ground wire into the lug and crimp using a crimping tool or a set of pliers. Reinstall the
lug to its original location. Note that all terminal block mounting bracket screws do not need to be removed during
Earth Ground installation. It is recommended that only the screws holding the lugs to the bracket be removed.
Regardless of ordered options, all Enclosures come equipped to electrically accommodate eight meters.
Therefore, some terminal blocks may be unused.
WARNING
AC and DC input signals and power supply voltages can be hazardous. DO NOT
connect live wires to screw terminal plugs, and DO NOT insert, remove, or handle screw
terminal plugs with live wires connected.

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.
