Wind Speed Direction Transmitter

User’s Manual

I. Brief Introduction

The anemometer/wind vane combo unit provides precision wind speed wind direction relative to the turbine position. By relaying this data to the controller, the turbine can appropriately correct the turbine position based on wind speed direction.

II. Technical Index

1. Wind direction range: 0～3600, output analog 4～20mA, vs. 0～3600

Wind speed range: 0～60m/s, output analog DC0.7V～DC4V, vs. 0～60m/s

2. Environmental condition: -300C ～ 700C

3. Working power supply: DC24V ±20%, reverse connection protection,

4. Remote distance: 300m, (signal & power wire: 4x0.3mm2, heating wire 2x0.3mm2, 1.5m each)

6. Weight: about <1.5 kg.

III. Correspondence table between analog output wind speed.

Wind speed m/s 0 5 10 15 20 25 30

4～20mA 4.0 5.3 6.7 8.0 9.3 10.7 12.0

Wind speed m/s 35 40 45 50 55 60 65

4～20mA 13.3 14.7 16.0 17.3 18.7 20.0 /

Analog output is linear, with wind speed error formula ± (0.5+0.05 x actual wind speed) m/s

IV. Correspondence table between analog output wind direction angle

Angle range 0° 22.5° 45° 67.5° 90° 112.5° 135° 157.5° 180°

0-10v 0 0.625 1.25 1.875 2.5 3.125 3.75 4.375 5

Angle range 202.5° 225° 247.5° 270° 292.5 315 337.5 360°

0-10v 5.625 6.25 6.875 7.5 8.125 8.75 9.375 10

Analog output is linear; its output current corresponds to the rotary resistance of potentiometer.

VI. Installation Debugging

1. Mount weather station on supplied bracket, then attach bracket to turbine according to Figure No.1. Wind direction pointer needs to point towards blades as well as support connection once installed. Once energized when pointer is facing blades, readings should be 180°(12mA)

2. The provision about 7-core socket of leading-out wire on the transmitter:

1# - DC24V positive (red) 5# - spare

2# - DC24V negative (black)

3# - wind speed signal (yellow) (4-20mA)

4# - wind direction signal (green) (DC0-10V)

Signal wires should be shielded or separated from any high frequency lines.
