The UC5™ Spray Height Control system uses ultrasonic sensors mounted on the left, right, and center sections to automatically maintain a preset height of the entire boom above the ground or crop. With the introduction of this system, the well known height control performance that has been satisfying customers for years is now available through Ag Leader and AutoFarm displays, as well as a number of virtual terminal displays.

Fast and Reliable
For farm operators and custom applicators, speed can have a major impact on the bottom line. Manual operation of a sprayer in uneven field terrain may require reduced operating speeds for continual boom adjustments. Using sensor data, the UC5™ system makes responsive height adjustments allowing your booms to automatically follow the contours of the land.

Reduce Stress and Avoid Boom Damage
Using the UC5™ system reduces operator stress and fatigue with no need to move your head back and forth to monitor changes in field terrain. The UC5™ system takes control of managing the boom by monitoring field contours and making constant boom adjustments. This allows the operator to focus on proper coverage and safety.

Spray Day or Night
NORAC’s ultrasonic sensors do not need light to measure boom height. Take advantage of favorable spraying conditions by extending working hours well into the night with the ability to spray in any light condition.

Intelligent, Durable, Efficient

• Automatically maintains a preset tip height above the ground (Soil Mode) or crop (Crop Mode).
• Controls all geometries of the boom.
• Communicates hydraulic valve activity
• May be overridden using the sprayers existing in-cab controls.
• Indicates whether the system is in ‘Automatic’ or ‘Manual’ modes.
• Adjusts your spray nozzle height on-the-go with the push of a button.
• Displays the height nozzle tips are from the target.
• Quick and easy to use with NORAC’s automated setup and user-friendly interface.
• On select sprayers, Automatic Headland Mode for controlling boom height on headlands.
• Automatic oil temperature compensation for improved performance.

More Efficient Use of Chemicals
The UC5™ maintains the booms at an entered preset height. Regulating spray nozzles at the recommended spray tip height above ground/crop results in the optimum spray pattern to disperse chemicals evenly and reduce drift.

Sensor 'Smarts'
The UC5™ ultrasonic signal can distinguish the ground from standing crop or field residue. Boom height is controlled by a choice of sensing soil surface (Soil Mode) or crop height (Crop Mode). Ultrasonic sensor hardware and software is designed by NORAC engineers specifically for sprayer boom height control applications.

Rugged, Reliable Ultrasonic Sensors

• Rugged aluminum sensors are designed for trouble free use.
• Internal electronics are epoxy sealed making them virtually impervious to moisture damage.
• Distinguishes changes in height to the nearest half-inch or centimeter.
• Sensor is able to distinguish the ground surface (Soil Mode) from standing crop (Crop Mode) or field residue.
• Break-away brackets are designed to provide superior protection to the sensors; spring loaded mounting bracket will bend approximately 90 degrees.

Roll Compensation
The patented Roll Control™ technology allows the NORAC system to monitor and compensate for boom center section roll. Without this technology, boom roll can only be controlled by making mechanical changes to boom design or by installing devices on the boom that prevent roll by physically making contact with the ground. The NORAC UC5™ system allows for effective control of the boom without altering the boom from its originally engineered design.

Accurate, Smooth Control
The UC5™ uses the stepless output of proportional valves for each wing to provide a more uniform method of boom control. NORAC-supplied proportional valves ensure that height corrections are smooth, even, and automatic.
