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 Washers 1/4" Lock Washers 1/4" Hex Nuts U-Bolts Nut Plate .05" Allen Wrench 1/4" x 3" Lag Screws #4 x 1-1/8" Machine Screw #4 Tooth Lock Washer #4 Flat Washer #4-40 Hex Nut Vantage Pro Plus ISS ISS FARS D014 Page 3 Thursday, July 5, 2001 4:18 PM Page 4Draft 7/5/01Fan-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.

Product # 6150, 6150C, 6160, 6160C I NTEGRATED S ENSOR S UITE I NSTALLATION M ANUAL For Vantage Pro TM or Vantage Pro Plus TM The Integrated Sensor Suite (ISS) collects several types of weather readings for display at your Vantage Pro TM console. The data is sent to the console either through a cable or by wireless transmission, depending on the version. With Wireless Vantage Pro TM , the Integrated Sensor Suite (ISS) can be used as one of eight sensor stations transmitting to your console/receiver(s). See “Additional Mounting Options” and “Appendix A: Wireless Transmitter IDs”. The Integrated Sensor Suite for Vantage Pro TM measures weather conditions: ✦ Wind Speed ✦ Wind Direction ✦ Rainfall ✦ Outside Temperature ✦ Outside Humidity The Integrated Sensor Suite for Vantage Pro Plus TM also measures: ✦ Ultraviolet Radiation (UV) ✦ Solar Radiation Note: To upgrade a Vantage Pro system to Vantage Pro Plus, see “Appendix B: Optional Accessories”. For mounting purposes, the Integrated Sensor Suite (ISS) consists of two sides: the anemometer and the rain collector side. The rain collector side is a white plastic shelf with the black rain collector cone on top and the white radiation shield below. The two sides can be mounted either together on a single pole (see illustration at the top of this page), or separately . The anemometer has 40' (12 m) of cable. Note: When both sides of the ISS are mounted together with the anemometer arm pointing north, the solar panel on the rain collector side is facing south. In the Northern Hemisphere, this positions the solar panel for optimal exposure to the sun. (In the Southern Hemisphere, you will need to position the solar panel facing north for optimal sun exposure. When mounting both sides together, this means pointing the anemometer arm south and re-orienting the wind vane.)

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 alcohol). Once you have mounted the ISS in its final location, use the bubble level on each sensor as a guide to verify that the sensor is level. (To adjust, tighten or loosen the screws holding the sensor on the shelf.) Each sensor has 3' (0.9 m) of cable. If you need to position the sun sensors away from the rain collector side, use extension cables #7876 . Note: Not all cables are compatible with your Vantage Pro system. To be sure they will work, order Davis extension cables from your dealer or directly from Davis Instruments. To upgrade your Vantage Pro to Vantage Pro Plus, see “Optional Sensors for ISS” on page 28.
