8512 1.0 GENERAL DESCRIPTION This Wind Cone fixture is an 18-inch diameter by 8-foot long nylon wind sock mounted on a cylindrical framework attached to a pipe support by two bearing assemblies. The Wind Cone comes with a red obstruction light, four PAR 38 lamp holders mounted on the main support and a frangible coupling on the lower end of the main support shaft. The entire assembly is mounted on a base plate or rigid steel conduit elbow which is supplied by others. 2.0 GENERAL APPLICATION AND REQUIREMENTS The type L-806 is designed to indicate wind direction at airports. The wind cone fixture should be mounted in a location near the runway to give a true indication of wind velocity and direction. The cone assembly is designed to move freely about the vertical shaft to indicate the true direction of the wind for velocities in excess of three miles per hour. The lighting fixture assembly consists of four PAR 38 lamp holders spaced equally in a plane above the fabric cone to provide the horizontal candlepower values required by F.A.A. specification L-806. 3.0 WIND CONE SHAFT The main vertical support of the wind cone fixture is constructed of extra heavy 1-inch steel pipe. A frangible coupling is provided at the bottom of the main vertical support. 4.0 CYLINDRICAL SUPPORT AND BEARINGS The cone support consists of a tapered cylinder attached to the two ball bearings on the vertical support by means of two strap arms. A clamping ring is furnished for attaching the fabric cone to the inner end of the support. Each of the two bearing assemblies consists of a heavy duty ball bearing enclosed in a weatherproof housing. Alemite grease fittings are provided for lubrication. 1
8512 5.0 FABRIC CONE The cone is fabricated of water-proof white or orange nylon fabric in the shape of a truncated cone, 18 inches in diameter at the throat, 8 inches in diameter at the other end and 8 feet long. 6.0 JUNCTION BOX AND OBSTRUCTION LIGHT A type GRF fitting at the top of the vertical support serves as a support for the four PAR 38 lamp holders (or four horizontal arms, for reflector floodlights (-RF Option)), a wiring junction box and has a cover with hub to which the EOL, L-810 is attached per spec. The obstruction light fitting includes a standard type red prismatic globe as used on type EOL marker lights, and a lamp receptacle for a 116 watt 120 volt, A-21 clear bulb, medium screw base traffic signal lamp. 7.0 LIGHTING UNITS Four PAR 38 lamp holders are provided for illuminating the wind cone. Fixtures are arranged for 250 watt, 120 volt, bulb, medium screw base lamps. Lamps and lamp holders are adjusted for a 60 angle off the vertical (see Figure 1). 8.0 NOT USED 9.0 INSTALLATION ON GROUND Where the wind cone is to be installed near a runway, FAA specification L-806 requires that it shall be mounted on a frangible coupling. 10. WIRING Power required for the lighting on the wind cone is 120 volt AC or DC. Internal wiring utilizes #14 AWG THWN single conductor type wire. Voltage drop from the transformer vault to the wind cone should be held within 5% of line voltage by using wire of sufficient size. If the wire run from the transformer vault to the wind cone is exceptionally long, it may be more economical to utilize wires of a smaller size with a voltage booster transformer. Wires from the transformer vault may be brought up through the frangible coupling threaded into the base, and brought up through the inside of the pole to the condulet junction box at the top of the wind cone fixture. Access to the condulet junction box for wiring is obtained by removing the hub cover which requires the removal of four screws. Splices of the wires from the base of the standard to the four individual lighting fixtures should be made in the junction box. 11. GROUNDING This installation is to be grounded in accordance with FAA specification L-107 requirements. 2
8512 12. LUBRICATION The wind cone bearings are factory lubricated. Approximately once a year lubricate the bearings (each bearing housing is provided with an Alemite grease fitting) with Exxon Beacon #325 grease, or equivalent low temperature high quality silicone grease. NOTE Local environmental conditions may require more frequent lubrication. WARNING If at any time the wind cone does not rotate freely (in a 3 MPH or higher wind), thoroughly clean and relubricate the bearings. If the bearings are worn, so that there is binding at any point, replace both bearings immediately. 3
