Product Related Safety

Precautions

The WAV151 Wind Vane delivered to you has been tested

for safety and approved as shipped from the factory. Note

the following precautions:

WARNING Ground the product, and verify outdoor installation

grounding periodically to minimize shock hazard.

CAUTION Do not modify the unit. Improper modification can damage

the product or lead to malfunction.

ESD Protection

Electrostatic Discharge (ESD) can cause immediate or latent

damage to electronic circuits. Vaisala products are

adequately protected against ESD for their intended use.

However, it is possible to damage the product by delivering

electrostatic discharges when touching, removing, or

inserting any objects inside the equipment housing.

To make sure you are not delivering high static voltages

yourself:

- Handle ESD sensitive components on a properly

grounded and protected ESD workbench. When this is

not possible, ground yourself to the equipment chassis

before touching the boards. Ground yourself with a wrist

strap and a resistive connection cord. When neither of the

above is possible, touch a conductive part of the

equipment chassis with your other hand before touching

the boards.

User's Guide ________________________________________________________

6 ______________________________________________________ M210294en-A

- Always hold the boards by the edges and avoid touching

the component contacts.

Regulatory Compliances

The WAV151 complies with the following performance and

environmental test standards:

- Wind tunnel tests per ASTM standard method D5366-96

(for starting threshold, damping ratio, overshoot ratio, and

delay distance; refer to technical data)

- Exploratory vibration test per MIL-STD-167-1

- Humidity test per MIL-STD-810E, Method 507.3

- Salt fog test per MIL-STD-810E, Method 509.3

Warranty

For certain products Vaisala normally gives a limited one

year warranty. Please observe that any such warranty may

not be valid in case of damage due to normal wear and tear,

exceptional operating conditions, negligent handling or

installation, or unauthorized modifications. Please see the

applicable supply contract or conditions of sale for details of

the warranty for each product.

CHAPTER 2

PRODUCT OVERVIEW

This chapter introduces the WAV151 Wind Vane features

and advantages.

Introduction to WAV151 Wind Vane

The WAV151 Wind Vane is a counter-balanced, low-

threshold optoelectronic wind vane. Infrared LEDs and

phototransistors are mounted on six orbits on each side of a

6-bit GRAY-coded disc. Rotated by the vane, the disc

creates changes in the code received by the phototransistors.

The code is changed in steps of 5.6°, one bit at a time to

eliminate any ambiguities in the coding.

A heating element in the shaft tunnel keeps the temperature

of the bearings above the freezing level in cold climates.

Nominally, it provides 10 W of heating power. It is

recommended to use a thermostat switch in the sensor cross

arm for switching the heating power on below +4 °C.
