INTRODUCTION
Welcome
Congratulations on your purchase of the SymphoniePLUS3 data logger. The revolutionary
SymphoniePLUS3 data logger is part of the world’s most advanced Internet enabled data logger system.
SymphoniePLUS3 stores data on an SD card. With an iPack or iPackGPS, you can send data via your
Internet provider over an embedded standard, satellite, or cellular phone. You receive an email with an
attached data file at a chosen interval.
Built on the proven designs of the Symphonie and SymphoniePLUS, SymphoniePLUS3 offers 3 “flex”
channels compatible with either analog or digital sensors with the addition of an SCM. The universal
anemometer inputs of the SymphoniePLUS3 are compatible with most commonly used anemometers –
no SCMs required. Plug-in Signal Conditioning Modules (SCMs) are available and pre-configured to work
with analog sensors from NRG Systems or other manufacturers.
The look and feel of SymphoniePLUS3 as well as the menu structure and user programming tasks remain
largely unchanged from Symphonie and SymphoniePLUS. SCM auto-detection allows the logger to
display flex channel information according to whatever SCM is inserted in the corresponding channel. A
new programming feature in the SDR software allows logger programming using a laptop through the
iPack programming port. If you can program a SymphoniePLUS, you already know how to program a
SymphoniePLUS3.
The complete Internet enabled SymphoniePLUS3 data logger system is comprised of the
SymphoniePLUS3 data logger; iPackGPS kit for CDMA cellular, 2G/3G GSM cellular, or satellite
communications; plus Symphonie Data Retriever Software. The Ethernet-based iPackACCESS is also
available and is very well suited for use at reference towers where real time SCADA networks polling for
MODBUS data are utilized. Symphonie iPacks are shipped pre-configured for WindLinx wireless service.
WindLinx allows for uniform activation of communications services and features the WindLinx web
portal, which allows for remote management and monitoring of wireless account activity.

SymphoniePLUS3 Set-up Overview
SymphoniePLUS3 is a very flexible system for collecting data. When used as a standalone unit, data files
are retrieved manually through regular site visits. When used in conjunction with an iPack for
communication, data files are delivered to users as email attachments.
Standalone Users (no iPack)
Standalone SymphoniePLUS3 configuration is fairly straightforward for those familiar with data loggers.
Follow the sections on logger setup carefully. Standalone users may skip the headings in this manual
referring to iPacks and do not need to install the SDR software in order to configure a logger. All
software related operations including software installation can be skipped until files need to be
processed.

Internet Enabled Users (with iPack or iPackGPS installation)
This manual provides full instructions in a chronological order for the complete SymphoniePLUS3
system, including use of an iPack. To best use the manual, follow along from beginning to end during
your setup phase.
The term “iPack” as used throughout this manual refers to either the iPack or iPackGPS except where a
difference in programming or features is explicitly noted.
As of June 2010, all iPacks ship pre-configured for WindLinx wireless service.
Theory of Operation
The NRG Systems SymphoniePLUS3 data logger is an Internet ready, ultra-low power microprocessor-
controlled data logging system specifically designed for the wind energy industry. Addition of a wireless
based iPack with a small PV panel provides convenient autonomous power (with its built-in 12V battery
and charge controller), and allows for Internet transfer of data via email through wireless networks. The
Ethernet based iPackACCESS is suitable for windfarm reference towers which require real time and
statistical data for SCADA networks.
The SymphoniePLUS3 logger has a fixed averaging interval of 10 minutes. Each of the 15 channels’
averages, standard deviations, and other statistical values are calculated from continuous 1 second data
samples. Data intervals are calculated every 10 minutes, time stamped with the beginning time of each
interval and written to the SD Card (SD) at the top of each hour.
Symphonie Data Retriever (SDR) software is then used to process raw data files stored on your
computer either from an SD Reader or email. Configuration of iPacks is also performed by the SDR
software with the use of a programming cable.
Sensor scales and offsets programmed into the SymphoniePLUS3 logger can be edited later with SDR if
there is a mistake or if a sensor is added or changed. The parameters in SDR’s Site Information Editor are
used to create the tab-delimited text file (ASCII), so there is always an opportunity to make changes to
how the raw files will be processed before generating ASCII data files.
Features of the SymphoniePLUS3 Logger System
The SymphoniePLUS3 logger is a 15-channel data logger optimized for the needs of the wind resource
assessment user. It is designed to be easy to install and reliable in any climate. Wherever you need to
measure wind, no matter how demanding the environment, SymphoniePLUS3 and the “plug and play”
iPacks make data collection as easy as reading your email.
9 counter channels and 6 analog channels. SCM cards are required on 3 counter (“flex”) and 4
analog channels.
Requires no complex programming. Convenient “plug and play” Signal Conditioning Modules
(SCMs) are pre-configured for a large variety of additional sensors.
SymphoniePLUS3 uses standard, non-volatile Secure Digital (SD) Cards (SD) for data storage. The
included 128 MB SD card provides over 2 years of data storage.

PRECAUTIONS
Notes for First Time Users
It is recommended that you take the time to become familiar with your new logger and its operation
before going out in the field. Please read the manual and experiment with all the functions and features
of the SymphoniePLUS3 data logger.
Practice the following in your office before going to the field:
- Installing SCM cards
- Setting SymphoniePLUS3 parameters (through the keypad, or through the iPack with the iPack
programming cable)
- Attaching the sensors to the SymphoniePLUS3 logger
- Using the keypad
- Formatting and changing SD cards
- Changing batteries
- Installing and configuring iPacks (ALWAYS verify successful data transfer before field installation!)
- Using Symphonie Data Retriever Software
- Transferring data from the SD card to your PC
Grounding
Whenever coming in contact with the SymphoniePLUS3 logger, either in the field or indoors, it is good
practice to first grasp a piece of grounded (earthed) metal to avoid a potentially damaging electrostatic
discharge (ESD) to the logger.
Meteorological sensors, loggers, and towers will accumulate static charge unless they are properly
grounded. Both high wind speeds and low humidity increase the rate of charge accumulation. Static
charge can change the electric potential of the logger and sensors by thousands of volts relative to
ground. Charge will continue to accumulate until the developed voltage difference causes dielectric
breakdown and static discharge.
Electrostatic discharge will damage any scientific instrument, including a SymphoniePLUS3 logger. It is
very important that you ground your logger immediately after mounting and prior to connecting a
sensor. If a copper clad ground rod cannot be driven into the ground at the base of the tower, a
grounding cable should be buried in the ground for sufficient distance to reduce the resistance between
the logger ground stud and the earth. Failure to adequately ground a SymphoniePLUS3 logger will cause
damage to the logger, sensor damage, and loss of data.
Equipment that is not properly grounded is not covered by NRG Systems’ warranty.

Recharging the iPack Battery
Lead acid batteries such as the one used in NRG iPacks need to be kept fully charged. It is very important
to recharge the iPack before installing it in the field, especially after programming or communications
testing.
In addition, all lead acid batteries lose their capacity over time and will need to be replaced eventually.
The battery must be recharged if an iPack is kept in storage or is unused for any period of time.
An iPack battery charger is available from NRG Systems (item #3615).
Environmental Considerations
- Grounding requirements are site-specific; determine soil type before installation.
- Sensor cables become less flexible and are more easily damaged at very low temperatures.
- Make sure that all sensor cables are securely fastened to the tower so they do not flap in the
wind.
- Be sure that all connections are tight and securely fastened to ensure reliability in high winds.
- Low temperatures can diminish battery performance. Always use good quality alkaline batteries,
and always stay within reasonable limits when establishing your battery replacement schedule.
Replace alkaline batteries at least once per year to avoid leakage.
- Make sure that all sensor cables are spiral wrapped (2 wraps every three meters) around the
tower to discourage natural frequency vibrations. Use a high quality electrical tape rated for
extreme conditions to further secure the cables to the tower.
- Coat terminal connections with anti-corrosive or petroleum jelly to reduce corrosion.
Site Records
Understanding the assignment of site numbers is the single most important step in setting up a wind
assessment system.
- The SymphoniePLUS3 logger system requires that you assign a unique site number to each logger
site.
- The assigned site number must stay with the site even if the tower, sensors, and logger are
dismantled and moved to another location.
- An abandoned site number is never re-used or assigned to a new location. It remains as a
reference to the historical data from the abandoned site.
An accurate description of each site is essential to your wind measurement program. Your
SymphoniePLUS3 logger can be configured to label datasets with the following information:
- Latitude and longitude (programmed automatically when using iPackGPS)
- Site elevation (programmed automatically when using iPackGPS)
- Sensor heights
It is advisable to record additional site information that may help in the analysis of your data:

- Type of terrain (open plain, mountainous forest, etc.)
- Type and height of trees
- Type of climate
- A topographic map of the area
In the Appendices, we’ve provided some blank site data sheets that may be helpful in organizing site
information.
Additional procedures and recommendations for keeping good site records can be found in the
American Wind Energy Association’s siting standards document: Standard Procedures for Meteorological
Measurements at a Potential Wind Turbine Site. This document can be found on the AWEA web site,
www.awea.org.

- In this manner, the digits 0-9, the entire alphabet, as well as special characters, can all be entered
utilizing only ten keys.
- The zero [0] key can be used to enter a blank space or the characters “*” and “#.” Pressing the
[Home/Esc] key will always return the display to the Main Menu.
- Take some time to experiment with the keypad to become familiar with its operation.
Navigation keys
The keys in the top row are the navigation keys –left, down, up and right. These keys can be used to
page forward and backward, move the cursor on data entry screens, and enter decimal points “.” or
negative “-” characters. Additionally, the up and down keys are used to toggle between capital and
lower case letters in alphanumeric fields. The exception to this is that the up and down arrow keys are
used for the semi-colon and colon characters while in the Manual Dial screen of the iPackGPS.
Display
- The liquid crystal display is built into the logger to facilitate site visits and is activated by pressing
any key on the logger keypad. The user can view present wind conditions and logger parameters
without additional equipment.
- As a power saving function, the display will always shut off after one minute without any key inputs.
The logger continues to collect data while the display is off.
D-cell Batteries
The logger runs on standard D-cell batteries which are protected by a battery cover. Batteries should be
changed one at a time so that logging operations are not disrupted during the battery change.
To help prevent battery leakage and damage to the equipment, it is recommended that high quality
batteries are used, such as Duracell or Energizer.
D-Cell batteries should be changed at least once per year, regardless of the remaining charge.
Input connector
This male DB-62 connector interfaces to the field wiring panel. Sensor wires are connected to the field
wiring panel with the supplied NRG Systems screwdriver.
iPack access port
This port allows connection of the Programming Adapter for iPack and logger programming while the
iPack or iPackGPS is connected to the logger.
Ground stud
This 10-32 stud is designed to be connected directly to earth ground with the supplied ground cable. The
logger must be grounded!

Clock battery
A CR 2032 lithium battery powers the logger clock even if D-cell batteries are not present. This allows
the logger to retain date and time in the event of a reboot. Clock batteries will last many years under
normal use.
Clock battery warning LED
This LED illuminates if the clock battery has been installed backwards.
Reset Button
The SymphoniePLUS3 has a reset button in the event that a nearby lightning strike or ESD event causes
the internal electronics to lock up. It is located between the battery box and the clock battery.
- Should it become necessary to reset the SymphoniePLUS3 logger, place the provided sensor
screwdriver to the upper left of the “Channel 4” SCM slot and press.
- Resetting the unit will cause up to 10 minutes of data to be lost (depending on how long since data
was last written to memory) and will start a new data file.
- Any time the reset button is pressed, the logger will begin a new data file.
- SymphoniePLUS3 loggers with attached iPacks will initiate an automatic call (“cold boot call”) 10
minutes after the logger is powered up. If no antenna is attached or the call can’t be completed, no
attempt will be made to call again until the next scheduled call or a “Call Now” is initiated by the
user.
- All configuration settings and previously-collected data will be retained.
- The reset button can also be used during field installation to manually start a new data file if the
user wishes to bookend an event, such as a site commissioning.
Note that a reset can be also be initiated by the built-in watchdog in response to an ESD (electrostatic
discharge) event.
When an iPack is connected to a logger with no D-cells, this will also initiate a reset. The iPack provides
auxiliary power to the logger and therefore powers it up in the absence of D-cell batteries.
SD Card Slot
The SD memory card installs into this slot with the beveled front corner down.
To help minimize the risk of card failure and data loss, it’s recommended that a 128MB NRG-formatted
SD card be used in the PLUS3 logger.
Do not use the SD card for any other device besides the data logger. Improper formatting and/or data
loss may result.

Signal Conditioning Module (SCM) Card Slots
NRG SCM cards are small PCBs that, when inserted into the proper slots, configure the corresponding
channel on the SymphoniePLUS3 for a specific sensor output signal. SCM cards are used in channels 4-6
(counter channels) and 9-12 (analog channels)
Channels
The SymphoniePLUS3 Logger has 15 input channels; 6 are counters, 6 are analog, and 3 can be either.
Channels 1 –3 and 13 –15 (Counters)
Channels 1 through 3 and 13 through 15 have built-in sensor interfaces for both NRG anemometers and
for other anemometers such as the P2546A WindSensor, Thies First Class, Vector, etc.
Channels 4 –6 (Flex; counter or analog)
Flex channels 4-6 can be configured for anemometers or analog sensors by plugging an SCM into the
SCM slot corresponding to that channel. The SCM provides the electronics to configure the input for the
connected sensor. The SCM also sets up the channel as a speed (frequency) or totalizer for sensors such
as tipping-bucket rain gauges or kWh meters.
When you insert the SCM, the correct type of sensor should be automatically detected by the logger and
only show programming options appropriate for that type of sensor.
Channels 7 –12 (Analogs)
Channels 7 and 8 have built-in sensor interfaces for the NRG 200P wind vane, or other wind vanes with
similar output signals. Channels 9 through 12 are configured by plugging an SCM into the corresponding
SCM slot for that channel. The SCM provides the electronics to configure the input for the connected
sensor. Appropriate SCMs in analog channels 9 through 12 also describe to the logger whether the
analog channel is a vane or other type of analog sensor (relative humidity, barometric pressure,
temperature, etc.).
