Wind Speed Sensor 

6.1 

At the Evolution DX2 Controller 

 

Note:  Wind Speed sensor data management can only be 

performed through the use of the Evolution Central 
Computer system. 

6.1.1  Features and Benefits 

When used with a Rain Master Evolution Central Computer System, 
wind speed sensing provides the following features and benefits: 

 

Automatic system shutdown for wind (Wind too high) 

 

Automatic wind start up (Wind calm enough for normal 
operation) 

 

Graph of the last three hours of wind data at Evolution Central 
Computer 

 

6.1.2  Wind Speed Sensor Installation Checks 

Check to see that the cup assembly of the Wind Speed sensor rotates 
freely and does not drag to a stop. 

6.1.3  Wind Speed Sensor Information 

Accuracy:  

+/- 1.5% or 0.25 mph 

Maintenance:  The Wind Speed sensor bearings should be replaced 

every 12 to 24 months. The Wind Speed sensor should 
be rebuilt every 24 to 36 months. 

 

6.1.4  Wind Speed Sensor Interface 

The two wires from the Wind Speed sensor are connected to Input 4 ( + ) 
and Input 4 ( - ) on the Sensor Terminal board via the Weather Center 
terminal block. Either wire may be connected to either terminal 
connection.
