Figure 3: U-Bolt installation
Loosely screw on the nuts on the ends of the U-bolts. You will tighten these
later during final mounting. Final assembly is shown in Figure 4.
Figure 4: U-Bolts and nuts installed
The plate and U-Bolts are not yet needed at this stage but doing this now
may help avoid damaging wind vane and wind speed cups later on.
Handling of the sensor package with wind vane and speed cups installed to
install these bolts is more difficult and more likely to lead to damage.
2. Install wind speed cups
Push the wind speed cup assembly onto the shaft on the top side of the
sensor package, as shown in Figure 5 on the left side. Tighten the set screw,
with a Philips screwdriver (size PH0), as shown on the right side. Make sure
the cup assembly can rotate freely. There should be no noticeable friction
when it is turning.
