Draft 7/5/01 Page 3 The hardware shown here is provided for assembly and mounting: Additional Components on Vantage Pro Plus Vantage Pro Plus includes an ultraviolet (UV) sen-sor and a solar radiation sensor. These two sensors are on the rain collector side of your ISS. Note: Please make every effort when handling your ISS not to touch the small white diffusers on top of the UV and solar radiation sensors. Oil from the skin will reduce their sensitivity. Clean the diffusers using ethyl alcohol on a soft cloth (NOT rubbing alco- hol). Tools for Installation Refer to this section in your ISS Installation Manual. Preparing the Anemometer Refer to this section in your ISS Installation Manual. Disassembling the Radiation Shield The radiation shield must be disassembled in order to make necessary cable connections and to install batteries in the wireless version of the ISS, which is solar powered.1/4" Flat Washers1/4" Lock Washers1/4" Hex NutsU-BoltsNut Plate .05" Allen Wrench1/4" x 3" Lag Screws#4 x 1-1/8"Machine Screw#4 ToothLock Washer#4 FlatWasher#4-40Hex Nut Vantage Pro Plus ISS ISS FARS D014 Page 3 Thursday, July 5, 2001 4:18 PM
Page 4 Draft 7/5/01 Fan-Aspirated Radiation Shield The ISS sensors are connected by cables to the Sensor Interface Module (SIM), located inside the radiation shield. The SIM contains electronics which mea-sure and store weather values for transmission to the console via cable or radio waves. The radiation shield’s white plastic plates protect the SIM from sun and other sources of radiated and reflected heat, and from precipitation.Before installing the ISS, the radiation shield must be disassembled in order to perform the following tasks: ✦ Verify that the rain sensor cable is connected to the SIM ✦ Connect the anemometer sensor cable to the SIM ✦ Connect the console cable to the SIM (cabled versions only) ✦ Make power connections to the ISS ✦ Install batteries in the SIM and Fan Plate (wireless versions only) ✦ Change the transmitter ID for wireless communication, if necessary ✦ Verify that your console is receiving and displaying data Opening the Radiation Shield Open up the radiation shield by separating the top and bottom parts as shown in the following illustrations. 1.

Disassembling the Radiation Shield Draft 7/5/01 Page 5 2. Remove the three wing nuts, lock washers and flat washers located on the underside of the radiation shield. 3. Turn the ISS right-side up with the rain collector on top. 4. Hold onto the rain collector and left off the top part of the ISS, exposing the fan plate on the bottom part of the radia-tion shield.#8 Wing Nuts#8 Lock Washers#8 Flat WashersRemoving the Wing NutsIntegratedSensorSuiteFanAspiratedRadiationShieldSeparating the Radiation Shield ISS FARS D014 Page 5 Thursday, July 5, 2001 4:18 PM
Page 6 Draft 7/5/01 Fan-Aspirated Radiation Shield Verifying Sensor Connections: 1. Locate the SIM inside the radiation shield. 2. Verify that the rain sen-sor cable is plugged into the receptacle labeled “RAIN” on the SIM. 3. If you have a Vantage Pro Plus, verify that the UV and solar radiation sensors are plugged into the SIM. Connecting Anemometer to SIM Refer to this section in your ISS Installation Manual.

Cabled Vantage Pro: Powering the Fan Draft 7/5/01 Page 7 Cabled Vantage Pro: Powering the Fan 1. Locate the Junction Board on the fan plate. 2. Connect the AC-power adapter to the +5V connector on the Junction Board. 3. Plug the AC-power adapter into an AC outlet. 4. Check to see that the fan is turning. 5. Unplug the AC power adapter from the AC outlet until it has been mounted. 6. Secure the AC power cable to the fan plate with the supplied cable clip.

Page 8 Draft 7/5/01 Fan-Aspirated Radiation Shield Wireless Vantage Pro: Powering the Fan Installing the Batteries 1. Insert the O-ring in the groove around the edge of each bat-tery compartment. 2. Insert a NiCad battery in each compartment, matching the plus sign on the battery with the plus sign in the battery compartment. 3. Verify that the fan is working. 4. Remove the batteries unless you are ready to install the ISS in it’s final location. Oth-erwise, the batteries will dis-charge from powering the fan. 5. Attach the battery covers to the battery compartments using two #4 x 3/8” (9.5 mm) screws each. Reassembling the Radiation Shield 1. Check all SIM and Junction Board cable connections. 2. Install the Junction Board Cover as show below. 3. Place the flat washers, lock washers and plastic wing nuts over the studs. 4. Finger-tighten the wing nuts until they hold the radiation shield plates firmly in place. Preparing the Rain Collector Refer to this section in your ISS Installation Manual.

Fan-Aspirated ISS Options Draft 7/5/01 Page 9 Fan-Aspirated ISS Options Low-Current Fan Unit The optional low-current fan unit uses less power than the standard fan. This allows the solar-powered Fan-Aspirated ISS to run for a longer period of time during low-light conditions. It is recommended for use in extreme latitudes during the Winter months, in climates that experience extended periods of cloudy weather, or for any location with limited solar exposure. Fan-Aspirated ISS Maintenance ✦ Keep the surfaces clean as the Fan-Aspirated Radiation Shield is less effective when the surfaces are dirty. Remove dust from the solar panel and the screen with a damp cloth. ✦ Remove any debris that obstructs air flow between the radiation shield parts e.g., leaves, twigs, webs, and nests. ✦ Avoid spraying insect killer of any kind into the radiation shield as this may dam-age the sensors and the shield. ✦ Change the battery annually (solar models only) and also remove any debris lodged inside the unit at this time. Replacing Batteries 1. Retrieve your Fan-Aspirated ISS and place on a stable work surface. 2. Disassemble the Radiation Shield (See page 3). 3. Remove the old battery 4. Install a new battery 5. Assemble the Radiation Shield (See page 8). 6. Mount the Fan-Aspirated ISS in it’s previous location.ISS FARS D014 Page 9 Thursday, July 5, 2001 4:18 PM
