    The data logger does not draw power from the lithium battery while it is powered by a 12 VDC supply. In an WS-PRO2 stored at room temperature, the lithium battery should last approximately 10 years (less at temperature extremes). Where the WS-PRO2 is powered most or all of the time, the lithium cell should last much longer.

    A.1 Grounding system installation To prevent lightning damage to your equipment, Rain Bird recommends installing a grounding system for the equipment (including controllers, weather stations, and central control systems). The grounding system discharges lightning-induced electrical current into the earth rather than allow the surge to pass through power wires or field wires to your equipment’s electronic...

  • Page 85: Ground Rod Stacking

    Install the connecting wire in as straight a line as possible. If you must make a turn or bend in the wire, make the turn in a sweeping curve with a minimum radius of eight inches and a minimum included angle of 90°. To minimize resistance, the copper wire must be pre-welded to the grounding rods/plates, or welded to the rods/plates using an exothermic welding process at the site.

  • Page 86: Grounding System Designs

    Stacking ground rods increases the total effective rod length, decreasing ground resistance. Joining the rods together with threaded couplers forms a secure connection so the grounding rods can be assembled quickly and easily. FIGURE A-2.

Each radial consists of three, 5/8”-diameter x 8-foot long copper-clad grounding rods. The first rod in each radial must be at least eight feet from the equipment.

The alternate version of grounding design “Y” uses nine grounding rods to reduce ground resistance A.2.3 Grounding plate design The “Grounding Plate” design (shown in FIGURE A-7 (p. 86) and FIGURE A-8 (p. 86)) consists of one vertical 8-foot copper-clad grounding rod at least eight feet from the equipment, and a copper grounding plate (minimum dimensions 4 x 96 x .0625 in).

    Appendix B. Determining True North and wind sensor orientation The orientation of the WindSonic “North Arrow Markers” is found by reading a magnetic compass and applying the site-specific correction for magnetic declination; where the magnetic declination is the number of degrees between True North and Magnetic North. Magnetic declination for a specific site can be obtained from a USGS map, local airport, or through a NOAA web calculator (Online magnetic declination calculator...
  • Page 92 For example, the declination for Longmont, CO (10 June 2006) is 9.67°, thus True North is 360° – 9.67°, or 350.33° as read on a compass. Likewise, the declination for McHenry, IL (10 June 2006) is –2.68°, and True North is 0° – (–2.68°), or 2.68° as read on a compass. FIGURE B-2.

Connect one wire per CHG terminal block.  12. If the charging source is a solar panel, remove the blanket or box from the solar panel once it’s wired into the CH150, PS100 or PS150 regulator.
  • Page 104 NOTE: The power cable that carries the regulated 12 VDC power from the regulator in the external enclosure to the WS-PRO2 station enclosure has a two-pin connector on one end and tinned wires on the other.  13. Toggle the power switch on the regulator (CH100, PS100, CH150, or PS150) to the OFF position.
  • Page 105 NOTE: Since the power coming into the enclosure is regulated power coming from the external enclosure, the wiring inside the WS-PRO2 station enclosure needs to be different than the standard wiring.  17. If this is a retrofit, inside of the ET station enclosure, wires come through the enclosure wall from the POWER connector on the back of the station that used to be wired into the charge ports of the PS100 or PS150.
