4. Cover the set screw hole with one of the small round stickers included
with the 034B. One of these labels is already installed on the hub covering
the set screw that attaches the hub to the sensor. Extra labels are included
with the 034B to recover the holes if the sensor has to be disassembled for
maintenance.
The set screw holes must be covered with the labels to
prevent corrosion and assure the warranty.
5. Mount a CM200-series crossarm to the tripod or tower.
6. Orient the crossarm North-South, with the CM220 mount or 17953 Nu-
Rail® on the North end. Appendix C ,
Wind Direction Sensor Orientation
(p. C-1)
, contains detailed information on determining True North using a
compass and the magnetic declination for the site.
7. Remove the alignment screw at the base of the 034B (FIGURE 7-1 ).
8. Insert the 034B into the aluminum bushing provided with the sensor (see
FIGURE 7-1 ).
9. Align the hole in the bushing with that in the 034B base and replace the
screw (see FIGURE 7-1 ).
10. Insert the 034B/bushing into the Nu-Rail® fitting (FIGURE 7-1 ) or the
CM220’s U-bolt (FIGURE 7-2 ).
11. Align the sensor so that the counter weight points to true South and tighten
the set screws on the Nu-Rail® or U-bolts on the CM220. Final sensor
orientation is done after the datalogger has been programmed to measure
wind direction as described in Appendix C , Wind Direction Sensor
Orientation
(p. C-1)
.
12. Remove the shoulder screw to allow the vane to rotate (see FIGURE 7-1 ).
13. Attach the sensor cable to the six pin male connector on the 034B. Make
sure the connector is properly keyed. Finger tighten the knurled ring.
14. Route the sensor cable along the underside of the crossarm to the tripod or
tower, and to the instrument enclosure.
15. Secure the cable to the crossarm and tripod or tower using cable ties.
