6Operation
6.1 Initial Start Up
On the initial start up, after confirming the legal disclaimer, a screen will appear informing the
operator that an Automatic Setup must be performed. After confirming this screen, the
Automatic Setup will begin (Section 8.2). The Automatic Setup reminder at startup will also
be shown each time a firmware update is performed.
6.2 Main Run Screen
Once the system is correctly configured, it is very simple to use. After confirming the legal
disclaimer, the Run screen will appear. For a virtual terminal, from the display’s start up screen,
select the UC5™ icon. An image of the boom, with the height of each boom section is
displayed as shown in Figure 5.
To change between Automatic and Manual Mode, select the corresponding “AUTO” (A) or
“MANUAL” (M) button. When the UC5™ system is in Automatic Mode, the “AUTO” button
and the line under the top right boom section are green. When the “MANUAL” button is
green and the line under the top right boom section is black and dotted, the system is in
Manual Mode. If the boom is above normal working height (typically 80 inches/205 cm), a
warning message will appear requiring the boom to be lowered before allowing Automatic
Mode to be activated. The normal working height is customized for each sprayer type so it
may not be 80 inches (205 cm) on all sprayers.
Figure 4: Over Height Warning
When the UC5™ Spray Height Control system is in Automatic Mode, arrows will appear on
the screen above or below the boom sections. These arrows indicate the UC5™ is making a
correction to part of the boom in the displayed direction. Often times the correction will be
very small and there may not be a noticeable change in boom position.

In manual mode, the height displayed under each boom section is measured from the spray
nozzles to the soil (Soil Mode) or crop canopy (Crop Mode or Hybrid Mode). If there are five
height sensors on the sprayer, the height displayed is the average for each boom section. The
crop at the bottom of the screen indicates the mode the controller is in. If the green line is
above the crop, the system is in Crop Mode or Hybrid Mode. If the green line is below the
crop, the system is in Soil Mode.
The following applies to Virtual Terminal only:
When two or more virtual terminals are connected on the Display Bus, the Move to Next VT
button will appear on the Soft key area of the Run screen. This button allows the user to select
the preferred terminal on which to display the UC5 screen. By pressing this button the UC5
screen will move to next available terminal.
6.3 Settings
To change the NORAC UC5™ settings, select the Settings button as shown in Figure 6. The
Settings can be accessed at any time, regardless of being Automatic or Manual Mode. The
second setting screen is accessed by selecting the Next button as shown in Figure 7. When
the system is in Manual Mode more settings and options are available by selecting the Next
button as shown in Figure 9. These settings are discussed in later sections. If the system is in
Automatic Mode, the “MANUAL” button is displayed to be able to put the system into Manual
Mode (Figure 8 and Figure 10) and to change other settings.

Mode with Learned Crop Height Unchecked
Sensitivity:
The sensitivity can be adjusted from 1 to 10, with 5 being the default setting. A lower number
will reduce the system sensitivity. Higher settings will speed up the response and also create a
greater demand on the hydraulics.
Mode:
The Mode button allows the system to be changed between Soil Mode, Crop Mode and Hybrid
Mode. Soil Mode allows the sensors to read a height from the spray nozzles to the ground;
whereas Crop Mode will read the height from the spray nozzles to the top of the crop canopy.
Hybrid Mode is an improved Crop Mode and is recommended in place of Crop Mode. For
more information on Crop, Soil and Hybrid Mode refer to Section 7.4.
Target Height:
The target height is the height you would like the boom to be set at when spraying. When
operating in Soil Mode, the target height is measured from the spray nozzles to the soil. In
Crop Mode the target height is measured from the crop canopy to the spray nozzles. In
Hybrid Mode the target height is a combination of measurements to provide a more stable
estimate of the distance from the crop canopy to the sprayer nozzles.
Tips:
Some sprayers have the ability to fold in the boom tips and spray with only the inner sections of
the boom. If your sprayer has this ability and is equipped with a five sensor system (Severe
Terrain Kit; refer to Section 13.1), the check box should be unchecked when spraying with
the tips folded in (Tips Off).
When in Tips Off the two outer sensors on the wings will be disabled and only the inner wing
sensors will be used to control the height.
The check box is defaulted to be checked (Tips On) and will return to be checked anytime the
power is cycled. When spraying with the full boom, the check box should be checked (Tips
On) to allow the outer sensors to operate again.
Main Lift Reaction:
The main lift reaction time affects how long the main lift waits between adjustments. The main
lift reaction time can be adjusted from 0 to 5. A setting of 1 is slow and a setting of 5 is the

12
fastest reaction time. A reaction time of 0 turns the main lift control off. A slower main lift
reaction time can be beneficial in uneven crops to prevent the boom from making unnecessary
movements. A reaction time of zero can be beneficial in tall crops where the crop is being
pushed over by the sprayer chassis to prevent the center section from moving too low.
Setting Main Lift Reaction Situation
0 Off Tall Crops
1 Slowest Reaction Uneven Crops
5 Fastest Reaction Even Crops & Soil Mode
Slant Reaction:
The slant reaction time is how long the slant waits between adjustments. This setting is only
visible when the slant control is enabled. The slant reaction time can be adjusted from 0 to 5.
A setting of 1 is slow and a setting of 5 is the fastest reaction time. A reaction time of 0 turns
the slant control off. It is best to set the slant reaction to a low setting in flat fields as the slant
is generally not required in flat fields. It is best to set the slant reaction to a higher setting in
uneven terrain or on side hills. Setting the slant reaction too high will cause the boom to
oscillate and decrease the performance of the system.
Learned/Expected Crop Height:
The learned crop height setting is used when spraying in Hybrid Mode. When Learned Crop
Height is checked, the UC5 system will attempt to learn the average crop height using all crop
readings that are measured by the ultrasonic sensors. If Learned Crop Height is unchecked, the
operator can enter an expected crop height. The expected crop height is then used to try and
achieve a more accurate average crop height reading by excluding ultrasonic sensor readings
that are outside the acceptable distance from the expected crop height. In most situations
leaving the Learned Crop Height setting checked will provide adequate performance.
6.4 Sprayer Switches
When a sprayer switch is pressed, an arrow will be displayed on the screen showing which
function is being activated (Figure 5). For example, if the left up switch is pressed then an
arrow will be shown above the left boom pointing up. Some sprayer types do not support this
functionality.
Tilt Switches:
While in Automatic Mode if either left or right tilt boom switches are pressed, the
corresponding boom section will go into Manual Mode, but other boom sections will remain in
Automatic Mode. To return all boom sections to Automatic Mode, press the “AUTO” button.
If the Double Tap Wings function is enabled, the tilt down switches can be used to resume
Automatic Mode provided that at least one boom section is already in Automatic Mode.

13
Main Lift Switch:
While in Automatic Mode if the main lift up or down switch is momentarily pressed, the target
height is incrementally adjusted up or down. If the Double Tap Main option is enabled, this
feature is disabled.
If Headland Assist (Section 9.1) is enabled with the trigger as the main lift switch, then the
main lift switch will be used to control Headland Assist instead of the target height. The main
lift up switch will activate Headland Assist. By pressing main lift down, the system will return to
Automatic Mode.
Pressing and holding the main lift switch will always put the system into Manual Mode.
If the Double Tap Main function is enabled, the main lift down switch can be used to resume
Automatic Mode provided that at least one boom section is already in Automatic Mode.
6.5 Error Indicators
If an error is detected in the system, the Error button will appear in the upper left corner of
the screen as shown in Figure 13. The boom with the error will go to its Manual state with
the ‘M’ or ‘A’ on the display flashing depending on whether the system is in Auto or Manual
mode.
Selecting the Error button allows all active system errors to be viewed (Figure 14). To
navigate between multiple errors, use the Next and Previous arrow buttons.
Applies to ECHO™ Only
The sensor underneath the boom on the display will change color depending on the type of
error. If the sensor turns red, it indicates that the sensor has lost communication with system.
If the sensor turns orange, it indicates that there is no data for that sensor.

7Understanding the UC5™ System
The UC5™ 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. A discussion of settings and performance is given below
to clarify these situations.
7.1 Boom Reaction Time
Sprayer hydraulics and boom suspension systems are the governing components to boom
reaction time. The maximum hydraulic speed of the boom is determined by the sprayer
manufacturer and is not diminished by the addition of the UC5™ hydraulic system.
7.2 Ditches, Waterways and Outside Rounds
In many situations it is necessary to spray with one sensor reading over terrain that does not
reflect the same situation of the rest of the boom. These situations may arise when spraying
over ditches, waterways, or field edges. When spraying in these situations the operator must
remain alert and override the height controller when necessary.
7.3 Driving Through Ditches and Over Terraces
Changes in terrain such as driving over terraces or through ditches are special performance
situations. This type of terrain can cause the sprayer to pitch and roll significantly and when
operating at high speeds this can cause rapid changes in boom tip height. Sprayer hydraulic
systems are not capable of tip speeds high enough to correct for the boom tip error. There
are two solutions to this problem.
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. For a description of the NORAC Roll Control™, see Section 13.3.
7.4 Soil Mode, Crop Mode and Hybrid Mode
Height sensors use “smart sensor” technology, which take measurements from both the top of
crop canopy and from the soil surface. This allows the user to select Hybrid, 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. Hybrid Mode
uses a combination of the crop and soil readings to improve control.

15
Hybrid and Crop Mode are usually used when operating in mature cereal grains, row crops or
specialty crops. Soil Mode is generally used to follow the ground through young crops, stubble
or normal trash.
In row-crops, Hybrid Mode will work best with the sensor placed directly above a row.
Some crops will produce a more varying canopy than others. In these situations, the
severe terrain option (Section 13.1) 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. The crop behind a wheel will be
flattened, resulting in inaccurate readings and poor Crop Mode performance.
7.5 Sensing Further Ahead of the Boom
A common misconception is moving the sensor further ahead of the boom will increase
performance. Moving the sensor further ahead of the boom increases the distance between
the nozzle and sensor. This puts the sensor at a different location within the field than the
nozzles, which introduces a height error at the nozzles. In severe terrain this height error can
bring the nozzles close to the ground as the sensor reads over the crest of the hill or down a
ditch.
7.6 Height Sensor Limitations
The UC5™ sensors are designed and built specifically for agricultural purposes. However, the
ultrasonic transducer must be clean and dry for optimal performance. The foam disc fitted into
the bottom of the sensor protects the transducer from dust. If the protective foams become
wet from rain or drift from the spray nozzles the sensors may have trouble reading.
Furthermore, if the transducer itself becomes wet, leave the UC5™ system on, but in Manual
Mode. The transducer’s vibrations will clean itself of the water and after a few minutes it will
begin to function again.
The height sensors will provide height readings from 22 to 300cm (9 to 120 inches), under
typical conditions.
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.

16
8Setup
Once the UC5™ Spray Height Control system has been installed, 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. The alternative method is to use Manual Setup, which is intended for expert
users and troubleshooting.
8.1 Navigating to the UC5™ Setup Menu
To perform either the Automatic or Manual System Setup, the user must navigate to the Setup
screen. The system must be in Manual Mode to perform setups.
When the system is in Manual Mode, select
the Settings button.
Select the Next button.
Select the Setup button.
The Setup screen will be displayed.
