TurfWeather Weather Station
3.16 Wind Direction Sensor (P/N 14011) Removal and
Replacement Procedure
The removal and replacement of a TurfWeather weather station wind direction
sensor does not require training, special tools, or test equipment. The main
body of the weather station does not need to be opened, there is no electrical
hazard involved, and this procedure can be accomplished by anyone possessing
basic mechanical skills. Please read this entire procedure before beginning
work.
Tools Required:
9
½ inch wrench
9
5/16 inch wrench
9
¼ inch wrench
9
#2 Phillips screwdriver.
1. Preparation:
a. Turn the power switch on the weather station to the “OFF” position.
b. Disconnect the power input cable and ground wire connections from
the weather station, using the 5/16 inch wrench for the ground wire
connection.
c. Remove the weather station from its location by using the ½ inch
wrench to loosen the two U-bolt nuts that secure the weather station to
its mast. NOTE: Do not remove the mast bracket from the weather
station.
d. Bring the weather station to an enclosed location, preferably near the
Host computer, and place it on a flat stable surface.
2. Sensor Removal:
a. Identify the wind direction sensor as the black vane (arrow shaped)
sensor located on the top, rear of the weather station main body.
NOTE: Do not twist or place side pressure on the wind direction or
wind speed sensors at any time during this sensor
removal/replacement process as it may cause them to break off of the
weather station main body.
b. Just below the sensor moveable vane, there is a flexible “boot” that
will peel down from the top. Without using tools, peel the boot down,
rolling the edge back upon itself and the sensor mounting post. Take
care not to place side pressure on the sensor itself. This will expose
three wires connected to three separate threaded terminal studs, held
tight by ¼ inch nuts.
c. Using the ¼ inch wrench, loosen the nuts and remove the wires,
taking care to note which wires go on which threaded terminal studs.
d. Locate the single Phillips head screw on the side of the sensor body.
NOTE: This is NOT either of the screws next to the threaded terminal
studs. Using the Phillips screwdriver, remove the screw.
