CHAPTER 4

MAINTENANCE

This chapter provides information that is needed in the basic

maintenance of the WAV151 Wind Vane.

Periodic Maintenance

Cleaning

Heavy contamination in the vane, such as bird dropplets or

ice will deteriorate the accuracy of the wind vane. Clean the

vane when necessary.

Testing Proper Operation

The sensor will hold its accuracy in all conditions for 1 year.

If the rains are mostly casual and moderate, and the

atmospheric corrosion is typical, the sensor accuracy will

remain for 2 years.

However, the ball bearings must be checked once a year and

the sensor shaft rotated manually. To do this, remove the

vane assembly. To ensure proper operation, the shaft should

spin smoothly and it should not create any detectable noises.
