4 INSTALLATION PROCEDURE
4.1 E XISTING SYSTEM CHECK
It is necessary to check the existing system’s
functionality before installing the UC4+
system.
1. Drive your sprayer onto a flat piece of
land, with unobstructed boom movement
(e.g. no power lines).
2. Test that all boom functions operate
correctly. As you test each function
check it off in Table 4.
It is necessary to test the boom
functions in all directions

4.2 B OOM S PEED T EST
IMPORTANT:
Raise/lower all boom sections se eral
times to warm up the hydraulic system.
Grease all mo ing 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 5.
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 5, “Trial #1” for “Left UP”.
4. Lower the LEFT boom from its extreme
HIGH position to the BOTTOM of its
travel. Record this time in Table 5,
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 5.
6. Repeat Steps 1 through 5 for the RIGHT,
MAIN and ROLL functions.
Your sprayer may not ha e a roll
feature.
7. Average the three trials recorded for
each boom movement and record this
calculation in the “Average Time” slot in
Table 5.
8. These “Average Times” now represent
how quickly your system can react to
manual control. In Section 4.8, this
procedure is repeated with the UC4+
System installed for comparison and
troubleshooting purposes.

4.3 W ING S ENSOR I NSTALLATION
1. Assemble the Breakaway Sensor
Mounting Brackets (B11) as show in
Figure 4 and Figure 5.
Figure 4 – Breakaway Sensor Bracket
Exploded View
Figure 5 – 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 mounting brackets can be installed
with the mounting base behind (Figure
8) or in front of the tube (Figure 6).
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+ system
warranty at the end of the UC4+
Sprayer Boom 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 (see Figure 6 and
Figure 8)

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 9).
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 6).
Figure 6 – Another Acceptable Mounting
A oid mounting sensors in
locations where they may read
from parts of the boom as shown
in Figure 7.
Figure 7 - 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.

4.5 R OLL S ENSOR I NSTALLATION
Mount the roll sensors to the included
roll sensor brackets using the machine
screws and nylon lock nuts, as illustrated
in Figure 11.
The roll sensors must be mounted
tightly to the brackets.
Figure 11 - Mounting the Roll Sensor to
the Roll Sensor Mounting Bracket
When mounting the roll sensors, use the
following guidelines and refer to Figure 12.
a) The smaller the distance between A
and B in Figure 12, the better the
performance will be.
b) Ensure the roll sensors are sitting
relatively level when the sprayer
chassis and boom are level.
c) All roll sensors must be mounted
with the circular AMP connector
facing towards the Right-Hand
Wing (when looking from the rear
of the sprayer).

4.5.1 Intermediate Frame Roll
Sensor Mounting
1. It is often best to cable tie the
intermediate frame roll sensor in place.
When mounting the intermediate frame
roll sensor follow the guidelines and
refer to Figure 14.
The intermediate frame roll sensor
must be mounted on a portion of
the sprayer that does not pi ot and
is as close to the boom frame roll
sensor as possible (Figure 12).
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 14 – Intermediate Frame 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 15.
3. Cable-tie the temperature probe cable
and AMP (circular) connector securely
to a frame member.

4.5.2 Boom Frame Roll Sensor
Mounting
1. Use the supplied hardware to mount the
boom frame roll sensor (E04) as shown
in Figure 16.
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 C in
Figure 16).
b) Be sure to use the roll sensor
(without the temperature probe)
(E04) that has the lowest serial
number.
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 16 - 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.

17
4.5.3 Reference Frame Roll Sensor
Mounting
1. The reference frame roll sensor is to be
mounted on the chassis as shown in
Figure 17. Ensure that the roll sensor
cabling is pointing to the right side of the
sprayer (when looking from the rear).
Figure 17 – Reference Frame Roll
Sensor Mounting Location
2. Ensure that the roll sensor is relatively
level when the chassis is level.
3. Ensure that the Reference Frame roll
sensor has the highest roll sensor serial
number (not including the roll sensor
with the temperature probe).
4. Ensure the sensor is mounted adequately
and that the cable provides enough slack.
Check that the roll sensors and
cables will not interfere with, or
come into contact with any parts of
the sprayer.
