FCC ID: ZOC-IMI672A01
This device complies with part 15 of the FCC Rules. Operation is subject to the following
two conditions: (1) This device may not cause harmful interference, and (2) this device
must accept any interference received, including interference that may cause undesired
operation.
Changes or modifications not expressly approved by the party responsible for compliance
could void the user's authority to operate the equipment.
This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the instruction manual,
may cause harmful interference to radio communications. Operation of this equipment in
a residential area is likely to cause harmful interference in which case the user will be
required to correct the interference at his own expense.

Introduction
The EchoPlus® Wireless Junction Box is a one-way wireless transmitter, located in a
junction box, used for the condition monitoring of plant equipment through traditional
ICP® accelerometers. The junction box, will “wake up” at determined intervals (8 hours
by default) to measure and transmit vibration levels for all activated channels. An Echo®
Receiver connected to a computer with the Echo® Data Server software installed is
required to receive and collect transmissions. For information on the setup and
installation of the Echo® Receiver and Echo® Data Server, please consult the Echo®
Receiver System Manual.
Proper Handling
Proper handling of the EchoPlus® Wireless Vibration Junction Box is critical to
preventing damage. The following should be avoided:
•
•
•
•
•
•
•
Dropping the unit.
Hitting the unit against hard surfaces.
Submersing or spraying the units with fluids of any kind.
Touching the electronic components under cover.
Using excessive torque when mounting the unit.
Exposing the unit to temperatures above 170° F.
Exposing the box to any reactive chemicals.
Programming the EchoPlus® Wireless Junction Box
The Echo® Wireless Vibration Sensor can be programmed with a computer running the
Echo® Data Server software through a serial port on the computer.
Tip
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.

Attaching the Programming Cable
To begin programming the EchoPlus® Wireless Junction Box, open the enclosure and
connect a serial cable to the serial port located on the junction box and attach the
programming serial port (use the USB to RS232 adaptor if necessary).
Connecting to the Junction Box with the Echo® Data Server Software
Launch the PCB Echo® Data Server and click Echo® EchoPlus® Sensors under the
Configuration drop down menu in the upper left hand corner of the screen.
Page 5 of 13
The program will then ask if you wish to set up a Echo® Wireless Sensor or an EchoPlus®
Wireless Junction Box. Select “I want to add, update, or view an EchoPlus® unit’s
Parameters”.
Select the receiver that you would like this specific sensor attuned to. If you are using a
single receiver select the default setting.
The software will then ask if you would like to set up the junction box, the database, or
both. If this is the first time you are activating this sensor you must do both. Installing a
new junction box and configuration of the database is covered in the Echo® System Setup
Manual. We will continue by only changing the programming of the Echo® Sensor.
Select “I will only configure the Echo® device at this time” button and click Next.
Make sure the sensor is connected to the computer through the USB to RS232
programming cable and hit OK.

The connection window will appear. Select the appropriate COM port to which the cable
is connected.
Reading the Current Programmed Parameters
Click “Link to EchoPlus®” and the green light will illuminate indicating the connection
has been made. The fields at the right of the window will populate with the current
programmed parameters.
Tip
The Sensor ID is set at the factory and CANNOT be changed. This ID is
unique to each junction box and channel we manufacture. The factory
default the Transmission Interval is 8 hours, RVL is 0 (off), and the CF
Report Threshold is 0.15.

Explanation of Echo® Wireless Sensor Parameters
Sensor ID – The Sensor ID is a unique ID programmed for each channel of the junction
box and set at the factory. This number cannot be changed.
Transmission Interval – The Transmission Interval is the time between transmissions.
The factory default level is 8 hours. The junction box will “wake up” and make a
measurement on each active channel every 8 hours (3 times per day).
Tip
Decreasing the Transmission Interval will provide data more often;
however, transmitting more often will decrease battery life. Keep in
mind “more data is not better data” and may be more than you can
process and manage.
RVL (Residual Vibration Level) – This is the minimum Residual Vibration (that is,
vibration that is currently present) for the junction box to wake up and make a
measurement on that specific channel. If the current vibration is below the RVL, the
junction box will assume the equipment is turned off and will not waste power
transmitting unusable data. If the value is set to “0” this feature is disabled and will
always make a measurement.
CF Report Threshold – Because crest factor is the ratio of true peak divided by RMS
vibration, in some instances where the RMS value is extremely low (such as slow speed
equipment) the crest factor will appear exceptionally high. This report factor is the
minimum RMS level in g for the Crest Factor to be reported.
Sensor Status – The sensor status displays if the specific channel is enabled or disabled.
If no sensor is attached to a channel, it is recommended to disable the channel to save
power and avoid bulking the database with bad information.
Acceleration Gain – Gain value used to normalize and calibrate acceleration
measurements.
Velocity Gain – Gain value used to normalize and calibrate velocity measurements.
Calibrating the Junction Box to Specific Accelerometer Sensitivities
The EchoPlus® Wireless Junction Box can be calibrated to work with an accelerometer of
any sensitivity. It can also be used to fine tune and normalize data collected from sensors
with slightly different sensitivities. To do this, we need to get the specific Velocity Gain
and Acceleration Gain values.
Page 8 of 13
To start, click the Calibration dropdown and select Velocity Calibration.
In the calibration menu select the nominal sensitivity of each accelerometer. If you have
specific calibration values, input the actual accelerometer sensitivities next to the nominal
value. Click the Calculate button to compute the Velocity Gain needed for the sensitivity.
Page 9 of 13
Click Accept to accept the new gain values.
Close the window and the software will automatically import the new values to the
configuration window.
Page 10 of 13
To change velocity gain, again click the calibration menu and this time select
Acceleration Calibration.
In the calibration window enter the nominal sensitivities, and if available, the actual
sensitivities for each accelerometer. Click calculate to calculate the Acceleration Gain
values.
Page 11 of 13
Accept the values by clicking the accept button next to each accelerometer you wish to
update.
Close the window and the software will import those new values to the programming
screen.
Page 12 of 13
Click update to save the settings for each accelerometer you wish to make changes to.
After all settings are adjusted, close the window.
The database configuration window will open allowing the configuration of each channel
in the junction box. In this window each channel can be set for alarm and alert levels,
name and location, and other features. The setup of the database will be covered in the
“Echo® Wireless System Manual”.
After all database settings are acceptable, click finish to update the database.
Mounting
The Echo® Wireless Junction Box should be mounted in a clean and convenient location
where it can be accessed.
