WEATHERPAK M 1

WEATHERPAKM was specifically designed for use by Hazardous Materials Responders. The
following is a list of some of the features that make the WEATHERPAKM unique:

l WEATHERPAKM features an advanced electronic interface and unique automatic

networking capability. The advanced electronic interface allows the use of GPS and
SmartDetect™ and future enhancements.

l The ultrasonic wind sensor has no moving parts, is very accurate (particularly at very low

wind speeds), and does not require periodic calibration.

WEATHERPAKM features a multi-function, 10.1-inch full colour, flat panel touch

l

screen display (INTERCEPT®1 Display). Multiple windows display data from different
WEATHERPAKM weather stations.

Automatically updates CAMEO®/ALOHA®2 and most other plume modelling

l

software programs.

l Built-in electronic compass allows the WEATHERPAKM to be set up in any orientation –

will automatically determine True North and give you true wind direction.

l Set-up time is less than one minute.

l

The electrical connections are designed to be intrinsically safe and the housing and tower
are constructed of 6061-T6 aluminium, a non-corrosive and non-sparking alloy.

l Designed to withstand decontamination procedures. The WEATHERPAKM housing is

double O-ring sealed and dried with a desiccant to protect the electronics against
moisture.

l All electronics are grounded at a single point to protect the WEATHERPAKM against EMI

(electro-magnetic interference) and RFI (radio frequency interference), thus assuring
reliable data and transmission.

This manual will familiarize you with the installation, operation, and maintenance of the
WEATHERPAKM. Please read all of the instructions before attempting to operate or troubleshoot
the system.

2. Siting and setup

2.1 Siting considerations

The following siting considerations must be addressed:

2.1.1 Compass accuracy

The WEATHERPAKM contains an electronic compass for automatic alignment to True North. To
prevent erroneous compass readings, install the WEATHERPAKM at least 30 metres (99 feet)
laterally from large vans, buses, cranes, or other large magnetic objects. (The top of a van is
suitable, but next to it is not an ideal location).

WEATHERPAK M 3

2.1.2 Proper wind measurement

Locate the WEATHERPAKM away from obstructions such as trees and buildings. The distance
between wind sensors and the nearest obstruction should be ten times the height of the
obstruction.

2.1.3 Radio transmission

Deploy the WEATHERPAKM as close as safety permits to the hot zone. The WEATHERPAKM
UHF radio has a range of 5 to 7 miles line-of-sight.

CAUTION:
Do not attempt to transmit through structures containing steel, or through hills.

2.1.4 GPS operation

There is a GPS receiver inside the INTERCEPT display and a GPS receiver inside the
WEATHERPAKM. These GPS receivers work together and provide data to the SmartDetect™
firmware, which in turn furnishes direction and distance information for additional
WEATHERPAKM stations operating in the vicinity.

The GPS in the INTERCEPT display must be connected to an external GPS antenna. The receiver
will automatically begin to search for and track GPS satellite signals at power up. The antenna
must have good exposure to the sky.

The performance of a GPS receiver at power-up is determined largely by the availability and
accuracy of the satellite ephemeris data and the availability of a GPS system almanac. When the
WEATHERPAKM is powered-up, the GPS searches for satellites from a cold start (no almanac).
The GPS will begin to compute position solutions within the first two minutes.

NOTE:
Immediately power up the WEATHERPAKM system as soon as you arrive on site to allow the
GPS to find the satellite and computer position.

2.2 System assembly

2.2.1 INTERCEPT display connections

The INTERCEPT display is only available for the WEATHERPAKM. It contains the radio receiver.
The radio antenna receives the signal from the WEATHERPAKM using narrow band UHF or
spread spectrum. In addition, a GPS antenna and electronics allow the WEATHERPAKM location
to be shown in relation to the display location.

WEATHERPAK M 4

1. Connect the external GPS and radio antennas to the appropriate connectors on the side of

the INTERCEPT display (see FIGURE 2-1 (p. 5)).

FIGURE 2-1. Side of INTERCEPT display

2. When outputting data to the CAMEO/ALOHA plume modelling software, connect the USB

to serial data cable. (The Ethernet connection will only be used in rare instances where the
INTERCEPT display will be connected to a network).

3. Plug the INTERCEPT display power supply into an AC power source then insert the power

supply barrel connector into the power jack on the bottom of the display and tighten.

FIGURE 2-2. Bottom of INTERCEPT display

WEATHERPAK M 5

4. The power indicator light on the bezel illuminates as the display starts up. The INTERCEPT

application will automatically launch and begin receiving data from any WEATHERPAKM
units available.

FIGURE 2-3. Front of INTERCEPT display

2.2.2 Connecting to a computer with USB to serial converter

The INTERCEPT display comes with a USB-to-serial converter cable. Use this cable to connect the
display to a computer or server. The INTERCEPT software can be configured to output ALOHA
messages to the display USB ports.

2.2.3 Connecting to a computer with the Ethernet port

This method is to be employed only if the INTERCEPT display must be connected to a network.
Please contact Campbell Scientific for further information. Refer to the About this manual page
at the beginning of this document for the procedure of returning components to Campbell
Scientific.

2.2.4 Tripod and WEATHERPAKM setup

Assemble the tower in the following manner:

1. Insert and lock the legs onto the bottom section of the tower, forming the tower tripod
base.

2. Align the slot on the WEATHERPAKM with the guide pin on the quick release and push
straight in. The cam lock provides a precision sealed fit and may require an extra push to
seat the WEATHERPAKM properly.

CAUTION:
DO NOT screw the WEATHERPAKM onto the cam lock connector.

WEATHERPAK M 7

3. Once the weather station is properly seated, press the arms of the cam lock down to assure
a tight fit. The battery indicator light (on the tower junction box) should illuminate when
the WEATHERPAKM is properly seated into the cam lock.

4. Place the entire unit (upper tower section and WEATHERPAKM) onto the tripod, engage
the twist-lock and turn clockwise a quarter turn.

5. The WEATHERPAKM is now running and sampling data. When the WEATHERPAKM is
removed from the cam lock connector, it will stop sampling and shut itself off.

WEATHERPAK M 8

FIGURE 2-4. Tower setup

WEATHERPAK M 9

3. System operation

Once set up, the WEATHERPAKM automatically begins sampling weather conditions and
transmits data to the INTERCEPT display every 30 seconds. The INTERCEPT display takes
approximately 20 to 30 seconds to complete a startup routine. When this process is complete,
the plume modelling software requires five minutes of data before a valid plume can be
presented.

3.1 INTERCEPT display functions and operation

The INTERCEPT display is configured at the factory with the ID of the accompanying
WEATHERPAKM and display units. The display can receive and display data from multiple
WEATHERPAKM units, but the factory configured ID will act as the primary WEATHERPAKM.

The touch screen provides access to multiple windows that display weather data in a variety of
ways. There are two sections: Observer and Maintenance (click on either at the upper right
corner). The Observer section is where weather data is displayed. The Maintenance section is
where system status can be checked. In the Observer section there is a tab for Weather Summary
and WEATHERPAK. Additional WEATHERPAKM stations may be added by the user, and a new
tab would be added.

3.2 Observer section

4. WEATHERPAKM and plume
modelling software

When the WEATHERPAKM is assembled and operational and a computer is connected to the
INTERCEPT display, real-time data is available to run air dispersion plume modelling software.

The following shows of the steps taken to produce an ALOHA plume model on a computer. This
section assumes the user is familiar with ALOHA and that the program is properly loaded onto
the computer. Campbell Scientific recommends consulting the ALOHA website and/or a certified
CAMEO/ALOHA instructor for training, program details, and limitations.

1. Click the ALOHA desktop icon or select ALOHA from the Windows® Programs menu. An

Air Model Limitations dialogue box will appear with important notes on program
limitations. Read and click OK.

WEATHERPAK M 16

2. Confirm that your Site Data information provided in the Text Summary window is correct. If
required, use the SiteData drop-down menu to change data.

3. Go to SetUp > Chemical and select the appropriate chemical.

4. Select SetUp > Atmospheric > SAM Station to display series of dialogue boxes that require

user observations or assumptions.

NOTE:
Relative humidity is not captured automatically by the ALOHA model but may be
entered manually using data from the WEATHERPAKM display.

5. (Optional) To confirm that WEATHERPAKM data is being delivered to ALOHA, go to SAM
Options > Processed Data and the Processed SAM Data window will display the data
delivered to ALOHA.

NOTE:
The user gets a warning message in both the Text Summary and Processed SAM Data
windows if the WEATHERPAKM has been collecting data for less than five minutes.

6. ALOHA requires the SAM station to be operating for five minutes before selecting the
source of release (tank, pipe, direct, etc.). Go to SetUp > Source and select the leak source
such as tank. A series of dialogue boxes will appear requiring user observations or
assumptions.

7. Select Display > Threat Zone and the Level of Concern window will display the default
ERPG ranges. Select OK to show the plume footprint. Displaying the footprint in ALOHA is
essential before the plume can be overlaid on a MARPLOT® or other street map.

WEATHERPAK M 17

8. (Optional) Select the Display menu to produce graphs for source strength and
concentration.

FIGURE 4-1. ALOHA window

WEATHERPAK M 18

9. Select the Sharing menu to plot the plume onto a MARPLOT (or other) map. As weather
conditions change, the plume size and position will change on the map, shortly after the
WEATHERPAKM provides updated data.

NOTE:
MARPLOT software requires that the ALOHA window overlay the map window for the
map-plume to update automatically (FIGURE 4-2 (p. 19)).

FIGURE 4-2. ALOHA with MARPLOT map

WEATHERPAKM reads the sensors every second and calculates five-minute running averages.
The running averages are included with the INSTANTANEOUS data on the INTERCEPT display,
and subsequently the plume model. In addition, the WEATHERPAK calculates Sigma Theta,
which is an air turbulence measurement that affects the mixing or dispersion of a chemical in the
atmosphere. Sigma Theta is also referred to as stability.

The INSTANTANEOUS data is the last direct sensor reading prior to the thirty-second update and
the battery voltage. The operator may detect a trend such as wind shift by comparing the 5
MINUTE RUNNING AVERAGE and INSTANTANEOUS data. The WEATHERPAKM battery voltage
is also transmitted.

NOTE:
Replace the WEATHERPAKM batteries when the battery voltage falls below 10.7 VDC.

To display the ASCll data being sent by the WEATHERPAKM, go to Main > SAM Options and
select Raw Data. The data should be similar to the following:

421, 0.9, 225, 1.0, 23.9, 1.0, 226, 23.9, 14.0, 1917, 999, 46, 2536

WEATHERPAK M 19

Most of these numbers also appear in the Processed SAM Data window in ALOHA. The
differences are no labels and some additional numbers. In addition, this raw data is delivered in
metric units (millibars, m/s, °C), whereas the processed data is converted to standard English
units (inches, MPH, °F).

Two checksums are performed to ensure the message was sent correctly. The computer adds up
the ASCII value of the data line (each character, such as numbers, letters, and punctuation, have
a numeric value universal to all computers) to make sure the computer received the same
number that the WEATHERPAKM transmitted.

5. Maintenance

NOTE:
All factory repairs and recalibrations require a returned material authorization (RMA) number

and completion of the “Statement of Product Cleanliness and Decontamination” form. Refer
to the About this manual page at the beginning of this document for more information.

5.1 Periodic maintenance schedule

Perform routine maintenance on the WEATHERPAKM every 12 to 24 months to ensure that the
overall system and its sensors are within specification. In addition, the entire WEATHERPAK
should be examined for wear, damage, or other non-conforming variances.

5.2 Troubleshooting

CAUTION:

Taking the WEATHERPAKM or the INTERCEPT Display apart will void the warranty. If the
following procedures do not solve the problem, contact Campbell Scientific.

5.2.1 WEATHERPAKM

When completely assembled, the WEATHERPAKM system automatically powers up, locates True
North, and begins sampling the atmospheric conditions; it then transmits weather data every 30
seconds. If it does not, check the following:

l Confirm the WEATHERPAKM is properly secured in the cam lock connector on the tripod

tower.

l Check the batteries in the tower. The red LED voltage indicator light on the tripod tower

will remain illuminated when the battery voltage is higher than 10.7 VDC. If the LED
indicator is not illuminated or if it is flashing, replace the batteries with fresh alkaline D­cells. When replacing tower batteries, use only high-quality alkaline batteries.

CAUTION:
Do not use rechargeable or bargain batteries.

l Check the fuse. The in-line fuse holder is in the junction box at the top of the tripod tower.

Access the fuse by removing the two screws on the junction box cover. If the fuse is blown,

WEATHERPAK M 21

replace with an AGC3 fuse. If the fuse blows repeatedly, contact Campbell Scientific. See

Replacing tower batteries and fuse (p. 23).

If the INTERCEPT display does not illuminate shortly after the on/off button is pressed, check the
following:

l Be sure the INTERCEPT Display is plugged in and turned on. Double check the power cord

connections at the wall, power supply and bottom of the INTERCEPT Display. If this does
not correct the problem, contact Campbell Scientific.

5.2.2 Data receipt

If the WEATHERPAKM data does not update on the INTERCEPT display and the WEATHERPAK is
within range, check the following:

l Double check the power cord. Be certain the INTERCEPT display is plugged in and turned

on. Check the power indicator light on the On/Off button on the front panel.

l Make certain you have direct line-of-sight to the WEATHERPAKM, that it is within 5 to 7

miles, and not blocked by an obstruction such as hills, vehicles, or steel buildings.

l Check to see that both the WEATHERPAKM antenna and the receiving antenna are

securely connected.

l Reset the system by removing the WEATHERPAKM from the cam lock connector on the

tripod tower. Wait 10 seconds, then replace the WEATHERPAKM on the tower.

l Check the tripod battery voltage and ensure the batteries are properly aligned (positive

towards the top of the tower). Replace batteries if necessary. (Replacing tower batteries and

fuse (p. 23).)

5.2.3 Computer

If the INTERCEPT display shows data, but your computer is not receiving the data, do the
following:

l Check all the connections from the INTERCEPT display to the computer.

l Ensure that the most recent version of ALOHA software is installed on the computer. Some

earlier versions of ALOHA (e.g. ver. 5.2.1) need to be upgraded to work with an automatic
weather station like the WEATHERPAKM. The U.S. EPA provides CAMEO/ALOHA software
downloads, support, and information at its web site: www.epa.gov/cameo.

l Ensure that the virtual COM port configuration is not being used by another device.

ALOHA must receive data on COM 1, 2, 3 or 4. If these ports are used by other devices or if
Windows® has assigned ALOHA a port other than COM 1, 2, 3 or 4, the software will not

WEATHERPAK M 22

receive the weather station. For more information, refer to WEATHERPAKM USB

connection and set up (p. 27).

Error messages while running the plume model are coming from the plume modelling software.
If you get an error message:

l Consult the CAMEO/ALOHA web site: www.epa.gov/cameo.

l Contact Campbell Scientific. Although not certified CAMEO/ALOHA trainers or

representatives, we may be able to help.

5.3 Replacing tower batteries and fuse

WARNING:
Do not leave batteries in tower when storing or shipping tower assembly. Batteries may leak
causing damage to upper tower section.

5.3.1 Tower batteries

The WEATHERPAKM uses ten alkaline D-cell batteries, located in the upper vertical section of
the tower. Rechargeable and bargain batteries do not perform well in the WEATHERPAKM.
Always use high quality alkaline batteries. (See FIGURE 5-1 (p. 23).)

FIGURE 5-1. Battery Replacement

Remove the battery plug using a large screwdriver. Insert the blade of the screwdriver into the
slotted plug, gently push the spring-loaded plug, then rotate the plug one-quarter turn either
direction. The plug and spring will come out followed by the batteries. Insert the new batteries by
tilting the tower section at an angle of approximately 45 degrees. A steeper angle will cause the
batteries to impact the top terminal too forcefully denting the positive terminal of the batteries.
This may cause the batteries to leak or create a faulty electrical connection. Slide the batteries in,
positive end first, then replace the spring-loaded plug using the reverse procedure.

WEATHERPAK M 23

The red LED voltage indicator light on the tripod tower will remain illuminated when the battery
voltage is higher than 10.7VDC. View the precise battery voltage using the Weatherpak Status
window on the INTERCEPT display. If monitoring multiple WEATHERPAKM stations, ensure that
the status window for the appropriate WEATHERPAKM station is viewed by using the ALOHA
plume model. To use ALOHA, open it on the computer, and go to MISC > Processed SAM Data.
One of the items shown is battery voltage. With new batteries installed, the voltage should be
between approximately 13 and 15 volts.

5.3.2 Tower fuse

The in-line fuse is located in the tower junction box (see FIGURE 5-2 (p. 24)). Gain access to the
fuse holder by removing the two machine screws on the junction box faceplate; then carefully
separate the faceplate from the junction box. Inspect the in-line fuse and replace if necessary
with an AGC3 fuse.

Appendix A. Vehicle mounting
a WEATHERPAKM

The WEATHERPAKM weather station is primarily designed to be deployed in (or near) a Hazmat
hot zone and the system includes a portable 3-metre tower for this purpose. However,
customers have found it convenient to mount the system on a vehicle (or trailer) when the
WEATHERPAKM is used for other applications, such as wildland or structure fires. Any
WEATHERPAKM can be vehicle mounted; typically, one of the following methods is used:

1. Campbell Scientific offers a professional, turnkey vehicle mounting solution for the
WEATHERPAKM. We have modified a side mount telescopic pole (Model 530), provided
by Fire Resources Corporation, Inc., a premier manufacturer of emergency lighting
products, to accept the WEATHERPAKM. (See FIGURE A-1 (p. 25).) Please contact the
Campbell Scientific Sales Department for pricing and more information.

2. Campbell Scientific also sells an accessory that allows the user to adapt the
WEATHERPAKM to a mast of your choice. (See FIGURE A-2 (p. 26).) The WEATHERPAKM
Vehicle Adapter is a cam lock Quick-Release with a male 1 1/2-inch NPT (national pipe
thread) on the bottom and 25-foot cable.

FIGURE A-2. Vehicle mount adapter

Both options arrive with two-conductor bare wire connections that must be terminated on a
12VDC source. While we are available to advise you, it is ultimately the customers’ responsibility
to determine the best way to install these devices on their vehicle.

To use these mounting solutions, the WEATHERPAKM must be serial number 1325 or higher,
have radio telemetry, and a 17-pin cam lock connector.

Appendix B. WEATHERPAKM
USB connection and set up

Depending upon the type of connection, when the WEATHERPAKM system is first connected to
a computer, Windows® automatically establishes a communications link between the
WEATHERPAKM INTERCEPT display and the computer, which allows data to pass to the plume
model or other software. USB or Ethernet connections may require additional drivers.

1. Verify that data is being received from the WEATHERPAKM. Start ALOHA on the computer

and set the COM port to the com port the cable is plugged in to. Be certain the most recent
version of ALOHA is running. Check or download the most current version from the U.S.
EPA web site: www.epa.gov/cameo.

2. With the WEATHERPAKM set up and transmitting, open the ALOHA Text Summary
window. It should look similar to this:

WEATHERPAK M 27

If errors appear on this window, verify the computer is receiving data. To do this, in ALOHA,
go to SAM Options on the top menu bar and select Raw Data. A window displays a string
of numbers similar to the following. The data line should refresh every 30 seconds (window
blinks and overwrites the previous data string).
