Installing Mechanical Wind Sensor Set WA15
Mechanical Wind Sensor Set WA15 consists of a Vaisala Anemometer
WAA151, a Vaisala Wind Vane WAV151, a cross arm WAC151, a
junction box, and cabling.
Install WA15 as follows:
1.
Attach the cross arm to the top of a pole mast with the mounting
clamp. Check that vane end of the cross arm is pointing north as
shown in Figure 31 on page 69.
2.
Mount the sensors onto the cross arm as shown in Figure 32 on
page 71.
3.
Bind the cables to the mast with cable ties.
WARNING
Using a long cable between different units (sensors, transmitters, power
supplies, and displays) can cause a lethal surge voltage if a lightning
strike occurs in the vicinity. Always ground the mast equipment case
close to the mast with a short, low-resistance cable.
4.
Connect the sensor cables DRW222446 and DRW222447 to the
WIND1 and WIND2 connectors on the bottom of the enclosure;
see section Connecting Sensor Cables on page 95.
