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

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.
