Page 5: Mode Of Operation
3 Mode of Operation Wind direction The dynamic characteristics of the wind vane is achieved by the aluminum lightweight con- struction. The co-action of wind vane and balance weight results in a high damping ratio with small delay distance as excellent characteristic of the complete vane. The axis of the wind vane is running in ball bearings and carries a diametrically magnetized magnet at the inner end. -
Page 6: Recommendation Site Selection / Standard Installation
4 Recommendation Site Selection / Standard Installation In general wind measurement instruments should be able to detect the wind conditions of a large area. In order to obtain comparable values when determining the surface wind, meas- urements should be taken at a height of 10 meters over an even area with no obstacles. An area with no obstacles means that the distance between the wind direction transmitter and an obstacle should be at least 10 times the height of the obstacle (s. -

5.1 Wind Vane Mounting Before the wind direction transmitter can be installed at its selected site, the wind vane must be mounted on the housing. Tool: Not required. Process 1. Remove wind transmitter shaft and wind vane from the packing. ... -
Page 8: Mechanical Mounting And Alignment
5.2 Mechanical Mounting and Alignment Remark: The wiring must be prepared so far, that plug and cable have been pushed through instru- ment carrier, mast, traverse etc., and can be connected to the wind direction transmitter at the moment of the “Mechanical Mounting”, described in the following (please refer to chapter 5.3.). - Page 9 Tools: Hexagon socket wrench size 3 (Allen key). Procedure: 1. Push cable/ plug connector of the wind direction transmitter through the borehole of the mast, tube, arm etc. 2. Put wind direction transmitter on mast, tube, arm etc. 3. For the precise determination of the wind direction the wind direc- tion transmitter must be aligned northwards (geographical north).
