4 INSTALLATION PROCEDURE
4.1 E XISTING SYSTEM CHECK
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. 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

* Some sprayers may not have this
function.
4.2 B OOM S PEED T EST
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 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 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 5.
8. These “Average Times” now represent
how quickly your system can react to
manual control. In Section 1.1, this
procedure is repeated with the UC4+
Spray Height Control system installed
for comparison and troubleshooting
purposes.

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 sensor mounting brackets can be
installed with the mounting base
behind (Figure 8) or in front of the
tube (Figure 6).
It is advised to avoid mounting the
sensor bracket to a breakaway
portion of the boom because a
breakaway action can cause the
UC4+ Spray Height Control
system to force a boom close to the
ground.
Please refer to the UC4+ Spray Height
Control 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).
When installing the UC4+ sensors
(E02), start with the smallest serial
number on the left hand side
proceeding to the largest serial

12
number on the right hand side
(Figure 10).
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
Avoid 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.

4.4 MAIN LIFT SENSOR INSTALLATION
1. Assemble the main lift sensor bracket
(B11) as shown in Figure 11.
Figure 11 – Main Lift Sensor Bracket
2. The bracket can then be mounted to
the lowest frame member on the
center section of the sprayer. The
bracket should be mounted so the
sensor mounting collar is in
approximately the center of the
sprayer and ahead of the boom
(Figure 12 and Figure 13).
The sensor mounting collar must
not be behind the sprayer’s wheel.
The General Mounting Rules for
UC4+ Ultrasonic Sensors, from the
previous section, must be followed.

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 14.
The roll sensors must be mounted
tightly to the brackets.
The chassis roll sensor bracket
requires the tabs to be cut off. See
Figure 19.
Figure 14 – Mounting the Roll Sensor to
the Roll Sensor Mounting Bracket
When mounting the roll sensors, use the
following guidelines and refer to Figure
15.
a) The intermediate frame roll
sensor must have the lowest serial
number and the chassis roll
sensor must have the highest
serial number.
b) The smaller the distance between
A and B in Figure 15, the better
the performance will be.
c) Ensure the roll sensors are sitting
relatively level when the sprayer
chassis and boom are level.
d) The 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
The intermediate frame roll sensor
has the temperature probe on it.
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 16.
The intermediate frame 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 15).
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 16 – Intermediate 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 17.
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.
Figure 17 – Temperature Probe Attached

4.5.2 Reference Frame Roll Sensor
The reference frame roll sensor
should be the highest serial
number.
1. The reference frame (chassis) roll
sensor mounts directly beneath the top
parallel lift arm, as shown in Figure 18.
Figure 18 - Reference Frame Roll Sensor Mounting Location
2. To mount the reference frame roll
sensor it may be necessary to modify
the roll sensor mounting bracket, as
shown in Figure 19.
3. Ensure the sensor is mounted
adequately and that the cable provides
enough slack.

4.5.3 Boom Frame Roll Sensor
Mounting
The remaining roll sensor after
installing the Intermediate and
Chassis Roll sensors is the Boom
Frame Roll sensor
1. Use the supplied hardware to mount
the boom frame roll sensor (E04) as
shown in Figure 20.
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 20).
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 had wing (when looking from
the rear of the sprayer).
Figure 20 – 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.
