WS PRO LT
Weather Station
Installation Manual
This manual covers the procedure for installing your WS PRO LT weather station, for both direct connect
and wireless communication and for solar and DC powered options. Before installing the weather station(s)
at your site, read over the discussions of power sources, site selection, grounding, wireless communication
and direct connect weather stations.
Power Sources
Weather stations have an internal sealed rechargeable battery that must be recharged to assure continued
system function. For recharging the battery, a solar panel or a user supplied external DC power source that
has a nominal rating of 18 Vat 1 amp output is required.
Site Selection
The ideal site is representative of the general area, is level,and well away from obstructions such as
buildings, trees, and steep slopes. If obstructions exist, use the Ten Times the Height Rule,which is
illustrated in Figure 1.
Figure 1Ten Times the Height Rule.
For example, if the height of the tree T is 8 feet and the height of the shed H is 7 feet, install the weather
station at least 80 ft away from the tree (i.e., 10T = 10x8 =80 ft) and 70 ft away from the shed (i.e., 10H =
10x7 = 70 ft).
Do not place the weather station near a sprinkler where it is likely to be sprayed by water,as this will
change the rain reported by weather station.

Note: If your weather station will be inside a fence to discourage vandalism, the fence top must be lower
than the wind sensors even if the fence is chain-link.
Grounding
Outdoor cables may be subject to induced currents due to lightning or other environmental factors.
Therefore, proper grounding is imperative to avoid damage to the weather station and/or the Host
computer. Review document D31910 for grounding recommendations.
Wireless Communication Weather Station
Wireless communication weather stations are available for installations within ½ mile / 0.8 km (1/4 mile /
0.4 km for 2.4GHz models) of the central control computer.
This range assumes no obstructionsare in the line-of-sight. Line-of-sight is defined as a straight path
between a transmitting and receiving antenna that is unobstructed by intermediate topography or
obstructions. A clear line-of-sight is required to achieve the optimum transmission range. The affect of
obstructions on the transmission range can vary. Therefore,if obstructions lie within the line-of-sight, you
should test your radio transmissions before permanently installing your weather station .
Wireless weather stations are equipped with spread spectrum radios and include a second spread spectrum
radio that is installed at the central control computer.
To test the radio transmission of your weather station carry the weather station to the site then attempt to
communicate with the central control computer. If obstructions in the line of sight are preventing the
weather station from communicating, try the following:
•Relocate your weather station away from obstructions
•Remove the obstructions
•Mount the computer base station antenna outside of the building by running the antenna cable
through a window or cable run
•Use a higher gain antenna (optional) at the computer site
•Install a higher gain antenna (optional) on the roof of the computer base station building and align
it above the obstructions.
Direct Connect Weather Station
Direct connect weather stations are available for installations that require the weather station be placed
more than a ½ mile line of sight from the central control computer. They can be installed as far as 20,000
feet / 6,096 m (~3.8 miles) from the central control computer.
Computer Requirements
•Cirrus, NimbusII, or StratusII central control system with Automatic ET and Multiple Weather
Stations modules. Modules are optional with NimbusII and StratusII central control systems.
Note: The Multiple Weather Stations module is only required if multiple weather stations will be
connected to one central control system.
•Windows 98/2000 or XP Operating System
•Available COM Port

Installation Procedure
1. Mount a mast/pole 1.25” OD and 8 to 10 feet (312 cm) high on cement base.
2. Place your weather station assembly on top of the mast/pole with the base firmly seated on the top
edge of the mast/pole of (see Figure 6)
3. Loosely tighten the U-bolt nuts so that the weather station is stable but can be rotated on the mast/pole
(Figure 7).

4. As a reference, use a compass and rotate the weather station assembly until the reference line on the
wind direction sensor is aligned with the Magnetic North (see Figure 8).
5. Firmly tighten the U-Bolt nuts
6. Confirm the weather station is level by viewing the bull’s level on top of the weather station (see
Figure 9). Minor adjustments can be made by placing shims between the weather station base and the
top of the pole.
7. Connect the power source that will recharge the internal sealed rechargeable battery. For Solar
Powered weather stations, follow instructions below.
8. Remove the red cap from the solar radiation sensor (Figure 10).

9. Properly ground the weather station by connecting a #14 gauge wire to the earth ground lug located on
the base of the weather station. Refer to Grounding Recommendations document D31910 for
grounding recommendations.
10. Refer to Communication Wiring for direct connect weather stations.
11. Turn the key to the ON position and return to the computer site to confirm the weather station is
working properly.
Solar Panel Installation
The solar panel recharges the weather station internal battery. It has a 72 sq.inch surface area and
produces 5 watts, at a peak of 17.1 volts.
Figure 11 5W Solar Panel
1. Place the solar panel on the mast below the station to the maximum distance allowed by the
solar panel cable.
2. Loosely tighten the U-bolt so that the solar panel is stable but can be rotated on the mast or pole.
3. Use a compass to properly align the solar panel. If your site is in the northern hemisphere, the
glass surface of the panel should face south. If your site is in the southern hemisphere, the glass
surface of the panel should face north.
4. Connect the cable to the weather station connector labeled Solar Panel
5. Tighten the thumb screw and the U-bolt
