To adjust the roll control on the left side for the Norac UC4+ with a 100-foot boom:

1. Check the boom style:
- If it's a center pivot style boom (common for 100-foot booms), roll values should be around 70 to 120.
- If it's a trapeze style boom, values should be around 20 to 40.

2. Press and hold the "MANUAL" button from the run screen to view the roll values.

3. The left and right roll values should normally be within 10 of each other.

4. Adjust the roll gain settings based on boom speed:
- For example, if the boom speed is 10–15 inch/sec, set roll gain between 225 and a lower value depending on desired response.

Use the gain settings from the roll section:
- Roll speed 1–10 inch/sec: gain 254–225
- Roll speed 10–15 inch/sec: gain 225–...

Adjust the gain as needed to balance left and right roll values and maintain stability.

When the Norac UC4+ displays "* roll" and ends with "6 Absent," it means that the system is not receiving a good signal or reading from Sensor 6. This indicates that Sensor 6 may be disconnected, malfunctioning, or not properly aligned.

  • Page 6: Safety Precautions

    Safety Precautions The UC4+ Spray Height Control system will greatly improve your spraying 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

     This can take the stress out of spraying along obstacles such as fences because you only have to watch the boom along the obstacle, knowing that the UC4+ is maintaining the height on the rest of the boom sections. Smart Sensor Technology:  All sensors are designed by NORAC specifically for the agricultural industry.

  • Page 9: Height Sensors

    4.2 Height Sensors  Height sensors use an ultrasonic signal to measure distance to the ground or crop canopy.  Normally there are three height sensors used, but a system may have as many as 6 sensors. A sensor is mounted to the outer part of each boom tip, and another sensor is mounted to the center section.

  • Page 10: Operation

    Operation 5.1 Basic UC4+ Operation Upon power-up a sequence of messages are temporarily displayed on the control panel LCD screen. The system is ready for use once the run screen is displayed.  To access either the "SENSOR DISPLAY" or "SETUP" menus, ensure you are at the run screen.

  • Page 14: Understanding The Uc4+ System

    Understanding the UC4+ System The UC4+ Spray Height Control System will work well in most situations. As with any equipment, it is important that the operator remains 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 15: Soil Mode And Crop Mode

    6.4 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”...

    Setup When the control panel is turned on for the first time, the UC4+ control panel guides the operator through the Automatic System Setup. Normally the UC4+ 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 7.3.

  • Page 23: Manual Setup

    7.3 Manual Setup The UC4+ 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 24 Navigating to the Sensor Menu:  Ensure the UC4+ control panel is in manual mode, at the run screen.  Navigate to the "More?" menu prompt in the SENSOR DISPLAY menu. Toggle "AUTO (YES)" to confirm.  Navigate to the boom section you would like to change. Toggle "AUTO (YES)". The left channel menu prompts are shown below.

    9.6 Minimum Height Mode Minimum height mode is normally used only for systems with five sensors (severe terrain kit). Since the five sensor system has two wing sensors that average the height, it is possible to have a boom tip close to the ground while still maintaining an acceptable average height. The minimum height defines the lowest height in which a single sensor on the wings is allowed to ...

  • Page 40: Maintenance

     Replace the oil filter in the NORAC hydraulic manifold (PT# 104827) annually.  If necessary, contact your NORAC dealer to have the sensors recalibrated or repaired. A typical sensor can operate three to ten years without requiring attention.
