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.
