Model 020C Wind Direction Sensor

1. Remove the orientation screw from the base of the sensor column. Place

the sensor column in the bushing such that the hole in the bushing aligns

with the hole just vacated by the orientation screw. Replace the screw and

tighten until snug. Do not over-tighten.

2. Place the sensor and bushing in the right-angle mounting bracket or

Nurail

fitting.

3. Rotate the sensor and bushing such that the vane and orientation screw

point true south, ensuring that the notches on the sensor hub and column

align.

4. Tighten the u-bolt (CM220) or set screws (pn 1049).

5. Attach the sensor cable to the six-pin male connector on the 020C.
