  • Page 5: Operator Safety

    Operator Safety **************** DANGER **************** 1. Always ensure that the UC4 system is powered down or in Manual Mode: • before leaving the operator’s seat; • while the machine is not moving; • or when transporting the machine; 2. Under no circumstances should any service work be performed on the machinery while the UC4 system is in the Automatic Mode.

  • Page 7: Installation

    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.
  • Page 8 Special attention must be taken into consideration when mounting the center sensor, as explained in Section 4.3. Norac ultrasonic sensors are designed to work best in the brackets provided (shown above). If you decide to use a different style of sensor mount you may limit the performance of the sensor and/or void your warranty.

  • Page 9: Mounting The Center Sensor

    Figure 4 – Roll Control of the Center Frame 4.3 Mounting the Center Sensor Special attention is necessary when mounting the center roll sensor. Mounting the center roll sensor directly behind a sprayer tire may impair main lift control when operating in CROP MODE. Height readings from crop that is flattened by the sprayer wheel does not provide an accurate measurement of canopy height, resulting in poor performance.

  • Page 10: Adjust The Sensor Offset

    4.3.2 Adjust the Sensor Offset To compensate for the lack of crop in the “wheel track”, adjust the main lift sensor’s height reading offset (Zero Height) so that the sensor will read higher to match the average height of your crop. Carry out the following procedure using the UC4 control panel: Make sure you are in manual mode, at the operating screen.

  • Page 11: Power Cable

    Call NORAC Systems and describe your situation to get pricing for an additional sensor, cabling, and mounting brackets/hardware. Once you have your sensor in place and electrically connected, carry out the following steps via the control panel to configure your system for four-sensor operation.

  • Page 12: Sensor Cables

    4.5 Sensor Cables The ultrasound sensors are connected to the control panel via sensor cables. A "trunk" cable runs from the panel to the sprayer boom. From the trunk cable, a standard "branch" cable allows for connection of the two standard boom sensors and an optional center sensor (refer to Figure 5).

  • Page 13: Lcd Screen

    Figure 6 – UC4 Control Panel 4.6.1 LCD Screen During normal operation, the LCD screen will show the status of the system and allow you to examine or change settings. All settings for the UC4 system are stored in cyclic menus. This type of menu allows the user to access each menu entry by progressively toggling the appropriate switch.

  • Page 14: Auto/Manual Switch (Yes)

    where a setting cannot be changed, the +/- toggle switch is ignored. 4.6.4 AUTO/MANUAL switch (YES) The UC4 boom control system has two operational modes – automatic and manual. This switch changes the operational mode of the system. In automatic mode (AUTO), the control panel will regulate the height of each boom to a predetermined set point.

  • Page 15: System Operation

    System Operation This section outlines the system’s features and controls during basic field operation. Before you can operate your UC4 system in automatic, it needs to be configured either automatically or manually. If your panel will allow automatic mode as shown below, it has been configured. If your panel will not allow automatic mode, it will attempt to begin or resume automatic setup.

    5.1.1 Using the Toggle Switches All functions on the UC4 panel are activated using its three toggle switches. To access either the SENSOR DISPLAY or SETUP menus, make sure you are at the Normal Operating Screen. Toggle toward the word describing the menu you wish to access.

  • Page 18: Adjust The Target Height (Setpoint)

    5.1.3 Adjust the Target Height (Setpoint) Adjust the target height setting with the +/- switch while in AUTOMATIC MODE. The smallest target height setting allowed is called the minimum height override. By default the minimum height settings are 25 inches in soil mode, and 25 inches in crop mode.

  • Page 19: Understanding Performance Issues

    Some UC4 sprayer kits come complete with additional damper kits. Other sprayer models have damper kits available from the sprayer manufacturer or from Norac as optional equipment. Contact Norac or your sprayer dealer for more assistance. Boom Reaction Time There are two key factors that determine how quickly your boom can react to changes in terrain.
  • Page 20 Important design issues include the style of main boom mount (for example, center pivot or nonparallel links), the amount of mechanical damping and spring centering on the main boom mount, and whether a main boom roll system is available on the sprayer. All of these factors together determine the maximum sensitivity setting you can run on your UC4 system.
  • Page 21 Extra foams are shipped with your kit. The transducer is a maintenance item and can be replaced at Norac Service locations. Transducers can last from three to ten years, depending on conditions. Refer to Section 8.2 for more maintenance information.

  • Page 22: Understanding Crop Mode

    5.3 Understanding Crop Mode A unique feature of Norac’s ultrasonic sensors are their ability to operate in CROP mode. In this mode the sensor will track the first available sonic target. That is, when positioned over standing crop, the sensor will return the average height of the heads in a circular area below the sensor.
  • Page 23 panel. This is designed to provide a more stable response in crop mode. The tradeoff is that the system will also be slightly slower to respond in crop mode than in soil mode. Thin Crop Ultrasonic sensors operate by bouncing sound waves off of the desired target.
