4.1 Installation 

For proper installation of the UC4 boom control system please refer to the 
installation manual for your model of sprayer. 

4.2 Sensors 

Three sensors are provided with your UC4 boom control kit.  The sensors use 
ultrasound to measure the distance to the ground, or the top of the crop.  
Three sensors are required to provide good overall height management of the 
boom.  Two sensors are mounted on the outer sections of each wing (see 
Figure 2).  These sensors maintain each wing at the set target height 
independently. 

 

 

Figure 2 – UC4 Sensor and Mounting Bracket

 

 

The third sensor is mounted on the main boom (center section). The center 
sensor is useful for setting your initial spray height when you begin a field.  It 
is true that the center height will not change much, in consistent soil 
conditions, since both ends of the main boom follow the height of the power 
unit.  However, it is extremely difficult to accurately judge the boom’s actual 
height from the cab.  It is also normally quite difficult for the operator to see 
the center section nozzles.  It is common for operators to be in error from 8 to 
12 inches or more.  How often does your operator check nozzle height with a 
tape measure?  The UC4 panel will give you an actual height reading in the 
cab, and allow active control to the desired height.
