NOTICE:
Every effort has been made to ensure the
accuracy of the information contained in this
manual. All parts supplied are selected specially
to fit the sprayer to facilitate a complete
installation. However, NORAC cannot
guarantee all parts fit as intended due to the
variations of the sprayer by the manufacturer.
Please read this manual in its entirety
before attempting installation.
ATTENTION:
When installing the UC4+ Spray Height Control
system please be aware that at a point in the
installation your sprayer booms will be
inoperative until the installation is complete.
Any installation procedure requiring
boom movement will need to be done
first. Once the hydraulics have been
disconnected you must complete the electrical
installation before the booms become operative.

Example:
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.

4 INSTALLATION PROCEDURE
4.1 SPRAYER INSPECTION
It is necessary to check the existing
system’s functionality before installing the
UC4+ Spray Height Control system.
1. Drive your sprayer onto a flat piece of
land, with unobstructed boom
movement (e.g. no power lines).
2. Ensure the boom guide-rods are set to
the “tapered” position (factory setting)
3. Set boom suspension to be critically
damped (Figure 5). Adjust the boom
damper accordingly.
A) Unlock the pendulum, 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 5 –Boom Push Test- Critically
Damped
4. Inspect slide pads for excessive wear
5. Test that all boom functions operate
correctly. As you test each function
check it off in Table 3.
It is necessary to test the boom
functions in all directions

4.2 BOOM SPEED TEST
IMPORTANT:
Raise/lower all boom sections several
times to warm up the hydraulic
system. Grease all moving parts for
consistent results.
1. Lower each boom and main section as
close to the ground as possible.
2. Set your sprayer at field working RPM
on the throttle and mark this value in
Table 4.
You will need a stopwatch or a
watch that displays “seconds”
for the next step.
3. Raise the LEFT boom from its extreme
LOW position to the very TOP of its
travel. Record the time this takes in
Table 4, “Trial #1” for “Left UP”.

8
4. Lower the LEFT boom from its extreme
HIGH position to the BOTTOM of its
travel. Record this time in Table 4,
Trial #1 for “Left DOWN”.
Be careful when lowering the
booms so they don’t hit the
ground.
5. Similarly, record two more time trials
(Trial #2 & #3) for the LEFT boom and
record in Table 4.
6. Repeat Steps 1 through 5for the
RIGHT, MAIN and ROLL functions.
Your sprayer may not have a
roll feature.
7. Average the three trials recorded
for each boom movement and
record this calculation in the
“Average Time” slot in Table 4.
8. These “Average Times” now
represent how quickly your system
can react to manual control. In
Section 4.7, this procedure is
repeated with the UC4+ Spray
Height Control system installed for
comparison and troubleshooting
purposes.

4.3 ULTRASONIC SENSOR
INSTALLATION
1. Assemble the Breakaway Sensor
Mounting Brackets (B11) as show in
Figure 6 and Figure 7.
Figure 6 – Breakaway Sensor Bracket
Exploded View
Figure 7 – Breakaway Sensor
Mounting Bracket Assembly
To assemble the breakaway sensor
bracket:
a) Assemble the bolt and nut into the
collar.
b) Grease the bottom edge of the
collar and the angled tube of the
base.
c) Place the collar onto the angled tube
of the mounting base.
d) Install the spring between the collar
and the upper ring of the base.
e) Insert tube through assembly and
tighten the collar
2. Mount the sensor bracket onto the
boom.
If possible, mount the sensor
brackets while the booms are in
their folded position to ensure
that they will not interfere with
anything when the boom is
folded for transport.
3. The sensor mounting brackets can be
installed with the base behind (Figure
10) or in front of the tube (Figure 8).
Mounting the sensor bracket to
the break-away section of the
boom may cause the boom to
drop suddenly as a break-away
occurs. This will occur on
break-away sections which lift
as they break away.
For optimal boom tip
protection, it is recommended
that the sensor be mounted
within approximately two feet
(60cm) of the boom tip.
Please refer to the UC4+ Spray Height
Control system warranty at the end of
the UC4+ Spray Height Control
Operator’s Manual (M01) for implications.
4. Mount the NORAC UC4+ ultrasonic
sensor (E02) into the sensor brackets.
The sensors should be oriented forward
(ahead) of the boom (Figure 8 and
Figure 10).

11
When installing the UC4+
sensors (E02), start with the
smallest serial number on the
left hand side proceeding to the
largest serial number on the
right hand side (Figure 11).
5. Sensor cables should run through the
mounting bracket tube and then behind
the member the bracket is mounted
onto. Cable-tie the connector in place.
The cable must not be allowed to hang
below the boom (Figure 8).
Figure 8 – Another Acceptable
Mounting
Avoid mounting sensors in
locations where they may read
from parts of the boom as
shown in Figure 9.
Figure 9 – Poor Mounting
(Sensor reading off boom)
General mounting rules for UC4+
ultrasonic wing sensors:
a) In its lowest position, the sensor mouth
must be 9 inches or more from the
ground.
b) The bottom of the sensor must be at
least 9 inches in front of the spray
nozzles.
c) The bottom of the sensor must be at
least 9 inches above the spray nozzles.
d) Ensure that there are no obstructions
within a 12-inch diameter circle
projected directly below the center of
the sensor.
e) The sensor should be approximately
vertical at normal operating heights.

4.4 ROLL SENSOR INSTALLATION
Mount the roll sensors to the included
roll sensor brackets using the machine
screws and nylon lock nuts, as
illustrated in Figure 12.
The roll sensors must be
mounted tightly to the
brackets.
Figure 12 – Mounting the Roll Sensor
to the Roll Sensor Mounting Bracket
When mounting the roll sensors, use the
following guidelines and refer to Figure 13.
a) The smaller the distance between Aand
Bin Figure 13, the better the
performance will be.
b) Ensure the roll sensors are sitting
relatively level when the sprayer chassis
and boom are level.
c) Both roll sensors must be mounted with
the circular AMP connector facing
towards the Right-Hand Wing (when
looking from the rear of the sprayer).

4.4.1 Boom Frame Roll Sensor
Mounting
1. Use the supplied hardware to mount
the boom frame roll sensor (E04) as
shown in Figure 14.
When mounting the boom frame roll
sensor follow these guidelines:
a) To prevent bending the bracket, ensure
bolts are placed as close together as
possible (minimize Cin Figure 14).
b) Be sure to use the roll sensor without
the temperature probe (E04).
c) When the boom is centered (not rolled
over) the roll sensor should be level
with respect to the sprayer chassis.
d) It is best to mount the roll sensor to
the left hand trapeze link (when looking
from the rear of the sprayer).
e) The roll sensor AMP (circular)
connector MUST exit towards the
right hand wing (when looking from
the rear of the sprayer).
Figure 14 – Boom Frame Roll Sensor
Mounted to a Trapeze Link
2. Cable-tie the sensor connector to the
frame with enough slack to allow the
link to rotate.
Make sure the bracket does not
collide with any parts of the
sprayer when the boom
rotates. Also ensure there is
enough slack to allow the roll
sensor to rotate.

15
4.4.2 Chassis Roll Sensor Mounting
1. It is often best to cable tie the chassis
roll sensor in place. When mounting
the chassis roll sensor follow the
guidelines and refer to Figure 15.
The chassis roll sensor must be
mounted on a portion of the
sprayer that does not pivot and
is as close to the boom frame
roll sensor as possible (Figure
13).
a) Make sure you are using the roll
sensor with the temperature probe
(E03).
b) Ensure the roll sensor is level with
respect to the chassis.
c) The AMP (circular) connector
MUST exit towards the right
hand wing.
d) Make sure the temperature probe is
able to reach the side of the valve
block.
Figure 15 – Chassis Roll Sensor
Mounting
2. Fasten the temperature probe to the
UC4+ valve block, using the supplied
3/8”x1/2” bolt as shown in Figure 16.
3. Cable-tie the temperature probe cable
and AMP (circular) connector securely
to a frame member.
Check that the roll sensors and
cables will not interfere with, or
come into contact with any
parts of the sprayer.
