  • Page 6: Safety Precautions

    Safety Precautions The UC4.5 Spray Height Control system will greatly improve spray height accuracy and protect the boom against damage in a wide variety of field conditions. However, under some circumstances performance may be limited. The operator of the sprayer must remain alert at all times and override the automatic control when necessary.

  • Page 7: Key Features

    Key Features Non-contact Sensing:  Sensing is done using ultrasonic sensors which means no parts of the UC4.5 Spray Height Control System come in contact with the ground.  Using a non-contact system means there will be no additional forces put on the boom, which could cause damage to the sprayer boom.

  • Page 9: Height Sensors

     Roll sensors are important for measuring boom and sprayer roll dynamics.  Two roll sensors are normally used for a UC4.5 Spray Height Control System.  The mounting position of the roll sensors vary from sprayer to sprayer depending on boom geometry and suspension.

  • Page 10: Position Sensors

    Control Panel The UC4.5 control panel (Figure 4) is the main component of the UC4.5 Spray Height Control System. The control panel uses the readings from the ultrasonic sensors to control solenoid operated valves that in turn adjust the boom height. The control panel will: ...

     New settings take effect once the run screen is displayed. When the UC4.5 Height Control System is in automatic mode, arrows will appear on the screen indicating the UC4.5 system is making a correction. Often the correction will be very small and there may not be a noticeable change in boom position.

  • Page 13: Sprayer Switches

    Viewing the Sensor or Target Height: When in manual mode the run screen shows the average of all the sensor heights. In automatic mode the number shown on the run screen is the target height. Press to view the actual sensor heights. The left, right, and main (center) sensor heights are each displayed on a separate screen.

  • Page 14: Main Menu Settings

    Main Menu Settings Sensor Mode: Soil mode configures the sensors to read the height from the spray nozzles to the ground. Crop mode will read the height from the spray nozzles to the top of the crop canopy. Hybrid mode will use both the distance measured to the crop canopy and the distance measured to the ground to determine the crop height.

  • Page 16: Understanding The Uc4.5 System

    Understanding the UC4.5 System The UC4.5 Spray Height Control System will work well in most situations. As with any equipment, it is important that the operator remain alert at all times. There may be some situations and terrain where performance is limited and in these situations the operator must resume manual control of the booms.

  • Page 17: Sensing Further Ahead Of The Boom

     Some crops will produce a more varying canopy than others. In these situations, the severe terrain option (Section 9.1) will provide more representative measurements and better performance. Hybrid mode is recommended for uneven crops.  When mounting the main lift height sensor, ensure the sensor does not measure behind a wheel or tramline, when driving straight or turning.

  • Page 18: Setup

    Setup When the control panel is turned on for the first time, the UC4.5 control panel guides the operator through the Automatic System Setup. Normally the UC4.5 Spray Height Control System will automatically configure and calibrate itself to the sprayer. If this process does not produce the desired results, perform the Manual System Setup described in Section 8.3.
  • Page 19  Use the sprayer's manual controls to move the left boom up.  If the wrong boom moves or if the direction is incorrect, stop the setup. Consult the UC4.5 Installation Manual to check the hydraulic plumbing and electrical wiring of the system.

  • Page 23: Retune

    Retune From time to time it may be necessary to recalibrate (Retune) the UC4.5 electronics to the sprayer’s hydraulics. Examples of such times are:  A hydraulic solenoid valve has been changed.  The hydraulic pump has been changed or adjusted.

  • Page 24: Manual Setup

    Manual Setup The UC4.5 Spray Height Control System will not operate in automatic mode until the system has been configured. It is recommended that the Automatic System Setup be used, but if necessary, a manual system setup may be used. The manual system setup involves setting up each sensor (programming serial numbers and sensor locations) as well as tuning the hydraulic parameters manually.
  • Page 25 Navigating to the Sensor Menu:  Ensure the UC4.5 control panel is in manual mode, at the run screen.  Navigate to the "More?" menu prompt in the SENSOR DISPLAY ( ) menu. Press confirm.  Navigate to the boom section to be changed. Press .
  • Page 26 Calibrating the Sensor’s Height Reading (Zero Height):  Ensure the sprayer boom is unfolded and the sensors are located over bare soil or gravel. Position the boom at a normal working height. Do not conduct this procedure over standing crop or tall grass/weedy areas. It is recommended to perform this calibration in soil mode.
  • Page 27 8.3.2 Valve Tuning Each valve must be tuned correctly for optimum performance from the UC4.5 Spray Height Control System. When setting up the valves, the sprayer booms must have room to move in their full range of motion. Make sure there are no obstructions, such as power lines, that the booms may come into contact with.
  • Page 28 Automatic Dead Zone Calibration:  Follow Section 8.1.1 (level booms, working RPM, etc.) before proceeding.  Ensure the UC4.5 control panel is in manual mode, at the run screen.  Navigate to the "More?" menu prompt in the SETUP ( ) menu.

  • Page 41: Maintenance

    11 Maintenance The NORAC Spray Height Control system requires very little maintenance, but there are a few procedures that will ensure the system continues to work correctly for many years. Before each day:  It is highly recommended that the sprayer friction pads are greased. To ensure optimum performance this should be done daily.

  • Page 43: Sensors

    12.2 Sensors Height or roll sensor appears not to work (displays "NC" or "No Comm"):  "NC" or "No Comm" refers to no communication. This may be caused by a damaged or defective CANbus cable. Ensure all cables are connected correctly. The connections should be tight and free of corrosion.
  • Page 44  If the error appears in the new location, the sensor may not be functioning properly. Sensor Alignment: Proper sensor alignment is critical for proper UC4.5 performance.  When the boom is in its lowest position, the sensor mouth must be 22cm (9 inches) or more above the spray nozzles.

  • Page 45: Hydraulics

    Boom(s) will not raise or lower:  Ensure there is hydraulic oil being supplied at the Norac valve block and that there is pressure at the pressure port. The hydraulics will not work if the pressure and tank lines are reversed.
  • Page 46 The hydraulic oil is overheating:  Using the UC4.5 system at higher sensitivities may create a greater demand on the sprayer’s hydraulics. Try lowering the sensitivity.  Plumbing single acting systems as double acting with orifices in both "A" ports may reduce...

  • Page 47: Boom Stability

    12.4 Boom Stability The boom is unstable in automatic mode:  Ensure the sprayer’s boom suspension is operating correctly and moving freely. If the suspension is sticking or too loose the boom will be unstable. If the boom is unstable in manual mode, the height control system will not make it more stable.

  • Page 48: Setup Messages

     This message will be shown if the boom moves in the wrong direction of what is expected by the UC4.5 system. This may be caused by a wiring or hydraulic problem. An extremely under damped boom or high wind conditions may also cause this message to appear.
  • Page 49 The display is stuck at "Mot’n Dly" or "KP Stp 9" during an install or retune:  The sensor may be reading off the boom. Try moving the sensor to a better location.  The target may be too weak. Move the sprayer to a better location with either dirt or gravel on the ground.

  • Page 50: Operational Messages

    12.6 Operational Messages The following messages may appear during normal operation and may not indicate an error with the system. "NR" or "NoRdg":  This indicates the sensor is not receiving a good reading. It is normal to see this message occasionally, however if the message is constantly displayed there may be a problem with a sensor.
