Example:
The hoses and some fittings required for the hydraulic installation are NOT
included in this kit. The parts needed for complete installation of the UC4.5
Sprayer Height Control system are:
Fittings (*F03) to interface the VG hoses to the 6MB ports on the NORAC
valve block (4 are required for double-acting hydraulics and 2 are required for
single-acting hydraulics).
2 fittings (*F04) and 2 hoses (*H01) to interface the pressure and tank lines to
the 6MB P and T ports on the NORAC valve block.
2 tee fittings (*F05) may be needed to tee the pressure and tank hoses if the
sprayer has steering.
Do not use high speed power tools/drills when installing hardware.
The use of dielectric grease is not recommended on any NORAC electrical
connections.
To ensure all stainless steel hardware does not gall or seize apply a light coating of
the supplied Permatex Anti-seize grease to all threaded parts upon installation.
Permatex Anti-seize lubricant is preferred, but other similar anti-seize products
may be used.

4Existing System Check
The pre-install checklist is necessary to check the existing sprayer functionality and settings
before the installation.
1. Inspect boom suspension wear-pads for excessive wear and ensure the boom rotates freely.
2. Ensure the boom suspension is configured as a short-pendulum (hilly mode). Insert the
boom pin to constrain the long-pendulum suspension as shown in Figure 5.
Figure 5: Pin Location for Hilly Mode
3. This UC4.5-BC-RA1 kit is designed to control the Kverneland variable-geometry boom.
This requires that the boom is fitted with variable-geometry tilt cylinders. If this install
requires adding tilt cylinders; adjust the cylinders so they can drop the wings below
horizontal while still offering enough vertical lift to lift the wings into transport position.
For optimal performance, install the extended tilt cylinder forks (Figure 6) to allow the
variable geometry to be adjusted below horizontal. Ensure the Kverneland cabin controls
are enabled for controlling variable geometry
Figure 6: Extended Tilt Cylinder Forks

4. Set the boom suspension to be critically damped (Figure 7). Adjust the boom springs and
dampers accordingly.
A) Unlock the boom, and push boom tip down approximately 75 cm (30 inches).
B) Hold the boom steady for a moment, and release.
C) Ensure the boom returns to its relaxed state as quickly as possible, with little to
no overshoot.
Figure 7: Boom Push Test: Critically Damped
5. Adjust the slant speed of the boom until the full stroke of the slant cylinder (not the boom)
is 6 seconds (Figure 8). This is the time required for the slant cylinder to travel from fully
extended to fully retracted, or vice-versa.

5Ultrasonic Sensor Installation
5.1 Bracket Assembly
Assemble the breakaway sensor bracket as illustrated in Figure 9, following the instructions
below.
Figure 9: Breakaway Bracket Assembly
1. Compress the spring and insert it together with the collar into the base.
2. Slide the tube through the assembled part.
3. Using the bolt and nut, tighten the collar to the tube with the sensor tube centered.
4. Apply a small amount of grease to the rotating surfaces of the bracket.

11
5.2 Ultrasonic Sensor Serial Number Arrangement
When installing the sensors, start with the smallest serial number on the left-hand side, and
proceed to the largest serial number on the right hand side. Each sensor has a serial number
stamped on the sensor housing.
Apply a light coating of the supplied Permatex Anti-seize grease to all threaded
parts upon installation.
Figure 10: Sensor Serial Number Arrangement

5.3 Ultrasonic Sensor Mounting Guidelines
The following guidelines will ensure optimal sensor performance and prevent sensor
measurement error. These rules should be followed for both the wing sensors and the main
lift (middle) sensor.
1. In its lowest position, the sensor must be 9 inches (23 cm) or more from the ground (A).
2. The centerline of the acoustic cone should be approximately vertical at normal operating
heights (A).
3. The bottom of the sensor must be at least 9 inches in front of the spray nozzles and boom
structure (B). (This does not apply for the main lift sensor)
4. The bottom of the sensor must be at least 9 inches above the spray nozzles (C).
5. Ensure there are no other obstructions with a 12 inch (23 cm) diameter circle projected
directly below the sensor (D).
Figure 11: Sensor Mounting Guidelines

13
5.4 Wing Sensor Installation
1. The sensor bracket should be oriented forward (ahead of the boom).
2. Typically the best mounting location for the wing sensor brackets will be near the end of
the boom tips, approximately two feet (60cm) from the end.
3. Depending on the boom design, some breakaway sections will lift upwards as they break
back. If the sensor is mounted to this portion of the boom, the system will force the boom
downwards towards the ground as the boom folds backwards.
4. Mount the NORAC ultrasonic sensor into the sensor bracket and run the sensor cable
through the sensor tube.
A problem can arise if a sensor is not mounted correctly. It is possible for the
sensor to read off of the boom instead of the ground. This may only become
apparent once the control system is switched from soil to crop mode.
Also be careful that the sensor bracket does not collide with any other part of the
boom when the boom is folded to transport position. If possible, mount the sensor
brackets while the booms are folded to ensure they will not cause interference.

5.5 Mounting Location for Wing Bracket on HSA Boom
1. Mounting the NORAC UC4 breakaway bracket to the HSA aluminum boom will require
the use of a RAU aluminum boom clamp.
Figure 13: Sensor Bracket Mounted to Boom using RAU HSA Boom Clamp
2. Using this clamp will also require adjusting the width of the hole in the NORAC bracket to
accommodate the larger bolts and differences in dimensions between the 2 parts.
3. For best performance, the sensor should be mounted 1-2m in from the boom tip.
Depending on the size of the boom, this may require putting the sensor on the breakaway
bracket.
4. It may be necessary to create an adapter to mount the NORAC bracket to the RAU HSA
boom. This bracket, when used in conjunction with the RAU HSA boom clamp, will
prevent the boom from rotating down towards the ground due to the clamp slipping on the
aluminum.

5.6 Mounting Location for Wing Bracket on HSS Boom
1. Use the square bracket mounting plate and the included hardware to mount the UC4
bracket to the HSS boom, as illustrated.
Figure 15: HSS Boom
2. Mount the UC4 bracket to the HSS boom as shown below, inside of the break-away
section.

5.7 Main Lift Sensor Installation
1. The Main lift sensor bracket (B11) can be mounted as illustrated below. Ensure the cable is
safely routed to prevent damage from moving parts.
Figure 17: Main Lift Sensor Bracket Mounting - View from Beneath the Boom
2. In order to fit the bracket within the boom as illustrated, it is necessary to cut 90mm from
the bracket, and drill a new 10mm hole for the sensor, 12 mm from the tip.

6Roll Sensor Installation
6.1 Bracket Assembly
1. Securely mount the roll sensors to the included roll sensor brackets using the #6 machine
screws. Tighten screws to 10 in-lbs (1.1 Nm).
2. The orientation of the mounted roll sensor to the roll sensor bracket will depend on the
bracket mounting. The roll sensor CANbus connector must be pointing towards the right
side of the sprayer (when looking from the rear of the sprayer).
