Service, Repair, and Return
Policies and Instructions
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 ISO9001 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
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.

Introduction
The Echo® Wireless Vibration Sensor, Model 670A01, is a stand alone, battery powered,
wireless, industrial vibration sensor. Its primary function is to monitor the vibration of
machinery in condition monitoring and predictive maintenance applications. The sensor’s
measurements are optimized to be sensitive to most common machinery faults such as:
unbalance, misalignment, looseness, bearing faults and gear faults.
Echo® contains a one-way wireless transmitter that is designed to “wake up” at
preprogrammed intervals, make a series of overall vibration measurements, transmit them
to a receiver for processing, and go back to sleep to conserve battery power. The sensor is
activated or deactivated using a magnet to operate a magnetic switch in the unit. When
activated, the sensor immediately makes and transmits a measurement set and then goes
to sleep until its next transmission time. The default transmission interval is 8-hours (3
times per day). An LED in the unit provides visual feedback on the state of the sensor: off,
on but in sleep mode, measuring, transmitting and changing states.
The transmitted data is received by an Echo® Receiver, decoded, and sent via Ethernet to
a computer or server running the Echo® Monitoring Software. For additional information
on the Echo® Receiver and the Echo® Monitoring Software, please refer to their
respective manuals.
The Model RV670A01 Echo® Wireless Vibration Sensor with RV (Raw Vibration)
Output operates identically to the standard model and additionally, provides the raw
vibration signal for detailed diagnostic analysis. The unit has a connector on the side and
can be used with an optional Model 070A86 Echo® RV Output Cable for analysis. See
the “RV (Raw Vibration) Option” section of this manual for additional information.
Proper Handling
Proper handling of the Echo® Wireless Vibration Sensor is critical to preventing damage.
The following should be avoided:
Dropping the unit.
Submersing the units in fluids of any kind.
Mounting the sensor by twisting the housing.
Exposing the unit to temperatures above 158° F.
Exposing the cap to any reactive chemicals.
Caution - The sensor cap is easily cross threaded. To avoid cross threading, press down
lightly on the cap to compress the battery securing foam. Turn the cap counter-clockwise
until a click is heard to line up the threads. Turn the cap slowly and carefully clockwise
until the cap contacts the housing. If the cap does not thread easily, do not force it.

The sensor cap is made from a translucent polycarbonate material. This material was
chosen because it is tough, allows the transmitted RF signal to radiate out of the sensor,
permits visual feedback provided by the imbedded blue status LED, and reduces the
passage of ultraviolet (UV) rays. However, like any “plastic” material, it is compatible
with some chemicals but not others.
Included here is a general chemical compatibility chart for polycarbonate material taken
from information on the Internet. This data is not guaranteed but is offered as a general
guide to chemical compatibility. It is highly recommended that you look up the
compatibility of you specific chemical with polycarbonate material. If polycarbonate is
not compatible with the processes in your plant, contact IMI for potential options.

Programming the Echo® Wireless Vibration Sensor
Programming
The Echo® Wireless Vibration Sensor can be programmed with a computer running the
Echo® Monitoring Software through a serial port. While this is a serial port in the sensor,
a micro USB connector is used in order to fit into the small space. A special (optional)
Echo® Programming Cable, Model 070A87, is required.
Note: If your computer is not equipped with a serial port, a USB to RS232 adaptor can be
used. These are readily available from computer electronics vendors.
Connect the Echo® Programming Cable
In general, the Echo® Programming Cable should be connected to the computer’s serial
port prior to connecting it to the sensor. When prompted by the Echo® Monitoring
Software to connect to the Echo® device (instructions below) use the following
procedure. Unscrew and remove the cap to expose the micro USB port inside the sensor,
see photos below. Carefully attach the programming cable to the sensor port (use a USB
to RS232 adaptor if necessary). If the Programming Cable is connected to the computer’s
serial port, the LED will blink 5 times indicating that it is connected and ready to
communicate.

Factory Defaults
The factory defaults are defined below unless otherwise specified. See the explanation of
the parameters below.
Sensor ID is a unique factory set number for each sensor and cannot be changed.
Transmission Interval = 8 hours
RVL = 0 (off)
CF Repot Threshold = 0.02
Transmission Power = High
Transmission Band = 1
Explanation of Echo® Wireless Sensor Parameters
Parameters can be changed by using the up and down arrows or by typing the values in
the appropriate box. Click on the Set button by the parameter to actually program the
sensor.
Sensor ID
The Sensor ID is a unique ID programmed into and etched onto each sensor at the
factory. This number cannot be changed.
Transmission Interval
The Transmission Interval is the time between transmissions of measured data.
The factory default is 8 hours. That means the sensor will “wake up” and make a
measurement every 8 hours (3 times per day). At the default 8 hour transmission
interval, the primary lithium-thionyl chloride (Li-SOCl2) batteries are expected to
last in excess of 5 years.
Note: Decreasing the transmission interval (i.e., increasing the number of
measurements per day) will not only reduce battery life but will also use more
receiver bandwidth. Thus, fewer sensors can be used with a receiver. See the
Echo® Receiver User’s Manual for guidelines regarding the number of sensors
that can be used per receiver.
RVL (Residual Vibration Level)
The RVL is an rms velocity level in ips (inches/second). If it is set to 0 (zero), the
feature is off and the sensor will wake up at the programmed interval, make
measurements, and transmit them. If a value is set, the sensor will wale up at the
programmed interval and start a measurement. If the rms velocity is ≥ the RVL,
the measurement and transmission will proceed as normal. If the rms velocity is <
the RVL, the machine is assumed to be off and the measurement is terminated.
This both conserves battery power and minimizes the transmission of “bad data”.
CF Report Threshold
CF (crest factor) is the ratio of true peak acceleration divided by rms acceleration.
For a sine wave, this value is 1.414. Echo® sensors high pass filter both the true
Echo® Wireless Vibration Sensor Manual
Version 1.2, 2011-12-07
13
peak and rms acceleration measurements for better HFE (high frequency energy)
response. This type of filtered measurement generally provides an earlier warning
of bearing, gear, and other high frequency faults. It can also result in very low rms
acceleration readings (sometimes in the noise) for healthy machines, particularly
if they operate at slow speeds. The CF Report Threshold value is a minimum rms
acceleration level at which CF will be computed. If the rms acceleration is below
this value, CF is returned as zero.
Transmission Power
The Echo® Wireless Vibration Sensor transmits at 0.75 mW ERP (Effective
Radiated Power). In some cases, the sensor may be so close to the antenna and the
signal strength so strong, that the receiver will see “reflections” of the transmitted
signal. While this does not affect data accuracy, it can use unnecessary receiver
bandwidth to deal with the reflections. If the received signal from a sensor is > 65
dB, the Transmission Power should be changed from High to Low to eliminate
this problem. This will cause the transmitted power to be reduced by about 45 dB.
Transmission Band
The Echo® System can operate on 12 independent user selectable RF bands.
Sensors will only communicate with receivers that are set to the same band that
they are set to. This allows for large installations requiring hundreds or thousands
of sensors and in cases where distances are too far to be picked up by a single
antenna location.
Saving Changes to the Echo® Sensor
Click the Set button next to each field to be updated to program the value in the Echo®
Sensor. To verify the programming when all changes have been made, click the Read
Parameters button. When sensor programming is completed, click the X in the upper
right hand corner of the window.

following will be displayed. Click OK. For details on setting up the database, see the
Echo® Monitoring Software User’s Manual.
A screen similar to the following will be displayed. Ignore the screen and click Finish.
This will be used when you set up the actual database.

RV (Raw Vibration) Option
The Model RV670A01 Echo® Wireless Vibration Sensor with RV (Raw Vibration)
Output operates identically to the standard model, plus, it provides a raw vibration output
signal for detailed diagnostic analysis. The unit has a connector on the side of the housing
that can be used with an optional Model 070A86 Echo® RV Output Cable that provides
the analog acceleration signal directly from the embedded accelerometer.
The cable converts the standard constant current sensor power provided by most data
collectors to the low voltage supply required by the Echo® Sensor. To make raw vibration
measurements, remove the shorting cap on the RV output connector. Attach the 4-pin
connector on the cable to the RV output connector. Connect the BNC end to a data
collector and set sensor power to on in the data collector. The nominal sensitivity of the
raw signal is 100 mV/g and there is a ± 20 g range.
Note: Replace the shorting cap after raw vibration data is collected. Wireless operation of
the sensor will not work with it removed.

Mounting
The Echo® Wireless Vibration Sensor should be stud mounted on a clean, flat surface. It
is not recommended to mount the sensor with a magnet due to the size and mass of the
sensor. The correct mounting torque for the sensor is 3 to 5 ft-lb (4 to 7 N-m). It is also a
good idea to put a small amount of silicon grease on the bottom of the sensor before
mounting.
WARNING – Do NOT tighten the sensor by twisting on the housing. Damage to the
sensor WILL occur. Tighten to the correct torque using a wrench on the hex base.

Preparing the Surface
If a clean, flat spot is not available on the machine, it is recommended to prepare a flat
machined surface using an optional IMI Model 080A127 1” spot face tool, shown below.
This tool will prepare a flat surface and drill the appropriate pilot hole for a ¼-28 UNF
thread. A ¼-28 tap is NOT included with the spot face tool.
If you are unable to use a spot face tool on the machine, optional Model 080A118
