E. INSTALLING THE WIND SENSORS
Assembling the Wind Speed Sensor
Figure 7: Wind Speed Sensor
Locate the wind speed sensor body. (It has one cable attached.)
Remove and discard the red vinyl shipping bumper from the threaded shaft. (The
purpose of this shaft bumper is to protect the precision internal bearings from any
damage during shipment and pre-installation handling that might be caused by
accidental shock to the shaft.)
Place the wind cup/hub assembly on the threaded shaft of the wind speed sensor so
that the cup assembly rests on and mates to the inverted shaft nut which has been
installed at the factory.
Thread the lock nut (from the Hardware Kit) onto the shaft above the wind cup
assembly.
While holding the wind cup/hub assembly with one hand, use a 3/8" wrench to screw
the lock nut down onto the cup assembly. DO NOT OVER TIGHTEN.
Spin the wind cup/hub assembly to make sure the wind speed display is functional.
The number displayed on the front panel should be greater than zero.
