4 INSTALLATION PROCEDURE
4.1 EXISTING 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 3.
It is necessary to test the boom
functions in all directions

*Some sprayers may not have this function.
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”.
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 1through 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 4.8, this
procedure is repeated with the UC4+
Spray Height Control system installed
for comparison and troubleshooting
purposes.

4.3 WING SENSOR INSTALLATION
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).
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+ 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).

10
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
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 10.
Figure 10: 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 11 and Figure 12).
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 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
13.
The roll sensors must be
mounted tightly to the brackets.
Figure 13: Mounting the Roll Sensor
to the Roll Sensor Mounting Bracket
When mounting the roll sensors, use the
following guidelines and refer to Figure 14.
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 Aand
Bin Figure 14, the better the
performance will be.
c) Ensure the roll sensors are sitting
relatively level when the sprayer chassis
and boom are level.
d) 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 Boom Frame Roll Sensor
Mounting
1. Use the supplied hardware to mount
the boom frame roll sensor (E04) as
shown in Figure 15.
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 15).
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 15: 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
4.5.2 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 14).
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 (when looking from the
rear of the sprayer).
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 to the UC4+ Valve Block

4.5.3 Reference Frame Roll Sensor
Mounting
The reference frame roll sensor
should be the highest serial
number.
1. The reference frame (chassis) roll sensor
mounts on the left side of the rear axle
below the main up/down coils (Figure
18). The AMP (circular) connector
MUST exit towards the right hand
wing.
2. Ensure the sensor is mounted adequately
and that the cable provides enough slack.
Figure 18: Reference Frame Roll Sensor Mounting

4.6 HYDRAULIC INSTALLATION
WARNING!
The hydraulic system creates very
high pressure. Before disconnecting
any hydraulic lines ensure all pressure
has been bled from the system.
When changing the boom hydraulic
hoses leave the booms in
TRANSPORT POSITION.
IMPORTANT:
Component failure due to oil
contamination is not covered under
the UC4+ Spray Height Control
system warranty. It is recommended
that a qualified technician does the
hydraulic installation.
4.6.1 Valve Assembly
1. On a clean surface remove all plastic
plugs from the NORAC hydraulic Valve
(V01) (Figure 19).
Figure 19: NORAC Valve Block
2. Install the orifices (F08) into the "B"
ports with the notch facing outward
as shown in Figure 20.
3. Install the 6MB-6MJ fittings (F05) into
the “B” ports and tighten to 18 ft-lbs.
4. Install the 6MBP plugs (F09) into the
“A” ports and tighten to 18 ft-lbs.
