    • The first is for the operator to recognize these situations before they occur and manually raise the boom to a safe height. • The second is to add the NORAC Roll Control option, if one is available for the specific sprayer. This will compensate for the sprayer roll and make the required corrections faster and smoother, allowing for increased boom protection and higher spraying speeds.

  • Page 13: Sensing Further Ahead Of The Boom

    • In order to optimize sensor performance, the UC5 sensor has a minimum distance that it will read (also known as the blanking range). As a result, the UC5 sensor is designed to ignore targets closer than 8 inches (20cm) from the bottom of the sensor housing.

  • Page 14: Soil Mode And Crop Mode

    Soil Mode and Crop Mode • Height sensors use “smart sensor” technology, which take measurements from both the top of the crop canopy and from the soil surface. This allows the user to select either “Crop” or “Soil” mode. • In “Soil” mode the target height is measured from the soil to the sprayer nozzle. In “Crop” mode the target height is measured from the crop canopy to the sprayer nozzle.

  • Page 15: System Setup

    After the NORAC unlock code has been installed on the Ag Leader® InSight™ display, the UC5 functionality must be tested and the software must be tuned for the sprayer. There are two methods to setup the UC5 system. The recommended way is to use the automatic system setup as shown in Section 8.2.
