3.2 Height Sensors
Height sensors use an ultrasonic signal to measure distance to the ground or crop canopy.
Normally there are three height sensors used. A sensor is mounted to the outer part of
each boom tip, and another sensor is mounted to the center section.
3.3 Roll Sensors
Roll sensors are important for measuring boom and sprayer roll dynamics.
Two roll sensors are normally used for a UC5 Spray Height Control system.
The mounting position of the roll sensors vary from sprayer to sprayer depending on
boom geometry and suspension.
3.4 Modules
Normally there are three modules included: a control module, an input module, and a
valve module.
Module status is indicated by a LED. Shortly after power-up, the module should present a
solid green light, indicating the module is functioning and ready.

4 Operation
4.1 Main Run Screen
The majority of functional settings and controls can be accessed on the main run screen. An
image of the boom, with the height of each boom section is displayed.
To change between Automatic and Manual Mode, press the corresponding button. When the
boom is blue, the UC5 system is in Automatic Mode. When the boom is black, the UC5
system is in Manual Mode. If the boom is above normal working height, a warning message will
appear requiring permission to allow Automatic Mode.
When the UC5 Height Control system is in Automatic Mode, arrows will appear on the screen
above or below the boom sections. These arrows indicate the UC5 system 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.
Settings
Figure 2: Main Run-Screen
Auto / Manual
Button
The height displayed on the boom is measured from the spray nozzles to the soil (Soil Mode)
or to the crop canopy (Crop Mode). If there are five height sensors on the sprayer, the height
displayed is the average for each boom section.

4.2 Setting Control Options
To change these settings, click the Settings button to display the boom height control options
screen as shown in Figure 3.
Figure 3: Boom Height Control Settings Screen
Sensitivity:
The Sensitivity can be adjusted from 1 to 10, with 5 being the default setting. A lower number
will reduce the system sensitivity and improve stability. 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.
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.

4.3 Sprayer Manual Boom Height Switches
When a manual switch is pressed, an arrow will be displayed on the screen showing which
function is being activated. For example, if the left up switch is pressed then an up arrow will
be shown above the left boom.
Tilt (Variable Geometry) Switches:
While in Automatic Mode if either left or right tilt switches are pressed, the corresponding
boom section will go into Manual 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.
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.
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.
* Some sprayer types may not have all the functionality listed above.

5 Setup
There are two methods to setup the UC5 system. The recommended way is to use the
Automatic Setup as shown in Section 5.1. The alternative method is to use Manual Setup,
which is intended for expert users and troubleshooting.
5.1 Automatic System Setup
Unfold the sprayer in a location that is relatively level and where the sensors are over bare soil
or gravel. Do not conduct the Automatic Setup or Retune procedures over standing crop or
weeds/grass. Also, avoid concrete or asphalt surfaces.
Ensure the boom roll suspension system is functioning properly and smoothly. Friction on
wear surfaces can be relieved using lubricants (grease, etc) or adjustment. Properly tuned
suspension systems will optimize UC5 performance.
For best results, the hydraulic system should be under a normal load and at a normal working
temperature.
Start the solution pump and run the sprayer’s engine at a normal working RPM for the
entire setup.
Cycle all boom sections up and down manually for five minutes to warm the oil.
For pull-type sprayers, ensure any hydraulic flow controls are adjusted for normal field
operation.
Changing the hydraulic flow controls after or during the Automatic Setup will affect the
UC5 performance.
Important
All boom sections will move during the Automatic Setup.
People and equipment must be clear of sprayer boom.
Ensure the booms have sufficient range to lift fully and are clear of any power
lines.

Page 12
To start the setup press the “Automatic Setup” button from the Setup screen. The system will
go through the following steps as it progresses through the Automatic Setup. Some steps may
not be used depending on the sprayer type.
Select the sprayer type:
From the selection boxes, choose your sprayer make and model and then press the
Check button.
A list of precautions will be displayed. Press “Check” to continue.
A list of connected modules will be displayed. Press “Check” to continue.
Wiring Test:
The system will instruct you to move boom functions using the sprayer controls. Move
each boom as instructed on the display.
Sensor Detect:
You will then be instructed to manually adjust the boom height so the nozzles are 90 cm
(35 inches) from the ground on all sections. When the measured distance is 90 cm press
“Check”.
The system will now instruct you to press and hold “Check” while it detects the sensors
on the booms.
Boom Geometry Tuning:
Exit the cab and manually push either boom tip down 30 to 90 cm for a moment and then
let go. Do not walk near the sensors when approaching the boom. Stay at least 1 meter
from the sensor to not induce a measurement error.
Hydraulic Tuning:
Press and hold the “Check” button to continue with the hydraulic tuning. If “Check” is
released before the tuning is finished, simply press and hold again to continue the
procedure.
The system will display various messages as it is working. The messages are displayed for
informational purposes only. When the system is finished the hydraulic tuning the
Automatic Setup is complete.
5.2 Retune
On occasion it is necessary to recalibrate the hydraulics of the NORAC UC5 Height Control
system. When you press the “Retune” button from the Setup screen, the system will go
through only the “Hydraulic Tuning” portion of the Automatic Setup. You may want to
perform a Retune when:
A hydraulic solenoid has been changed.
A hydraulic pump has been changed or adjusted.
A different tractor has been connected to the sprayer.
The tractor’s hydraulic flow control has been adjusted.

6 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. This will ensure the boom is pivoting
separately from the sprayer. It is very important to keep the friction pads greased on
Active Roll™ systems.
Ensure the height sensor breakaway brackets are functioning correctly. Apply grease to the
moving parts if necessary, to ensure they return to center after a break-away occurs.
Ensure there is a clean, dry foam disc inserted in each sensor. If it is clogged with dust or
other debris, clean it as described below.
At the end of the season:
Replace the oil filter in the NORAC hydraulic manifold annually (NORAC P/N 106285).
Cleaning Ultrasonic Height Sensors:
Remove the foam disc from the sensor and wash it with clean water. Squeeze out excess
water and allow the foam disc to dry. The sensor can be used if the foam is wet, however
you may not get a valid height reading until it is completely dry.
If the transducer inside the sensor is also dirty, wash it using clean water. Remove the
sensor from the bracket and rinse debris from the transducer by pouring water
across the face of the sensor. Do not submerge or pressure-wash the sensor. A
soft bristle brush can also be used to gently clean the transducer if water alone is not
sufficient. Use caution not to scratch or tear the transducer as it is fragile. The sensor
should be left to dry with the transducer facing downwards. The sensor can be used if it is
wet, however you may not get a valid height reading until it is completely dry. Leaving the
control system powered on with the sensor connected and facing down will speed the
process of drying the sensor.
Chemicals or compressed air should never be used to clean the sensor.
