Figure 1 depicts the general system layout of the UC4+ Spray Height Control system.
Figure 1 – System Components and General Location
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.

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

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 1 through 5 for the RIGHT,
and MAIN 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.
Figure 4 – Breakaway Sensor Bracket
Exploded View
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.
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.
Figure 5 - Acceptable Mounting
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.
3. Mount the NORAC UC4+ ultrasonic
sensor (E02) into the sensor brackets.
The sensors should be oriented forward
(ahead) of the boom (Figure 5 and
Figure 7).
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 8).
4. 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 - Sensor Cable Routing
Avoid mounting sensors in
locations where they may read
from parts of the 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. Mount the main lift sensor with the bracket provided (B11). The sensor should point behind
the boom, but be ahead of the spray nozzles.
Make sure the sensor has clearance when the main section is raised and lowered.
2. Aim the sensor perpendicular to the ground. Tighten all the sensor bracket bolts.
General mounting rules for ultrasonic main lift sensor:
a) Mount the sensor at the midpoint of the main lift section.
b) The sensor must have a 12-inch diameter clear view of the ground without any obstructions.
c) Ensure that there will be no contact between the sensor and the booms when folding and
unfolding, or raising and lowering.
d) The bottom of the sensor must be at least 9 inches in front of the spray nozzles.
e) The bottom of the sensor must be at least 9 inches above the spray nozzles.

13
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
9.
The roll sensors must be mounted
tightly to the brackets.
Figure 9 – Mounting the Roll Sensor to
the Roll Sensor Mounting Bracket
1. When mounting the roll sensors use the
following guidelines and refer to Figure
10.
2. Ensure the roll sensors are sitting
relatively level when the sprayer chassis
and boom are level.
3. 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).

Figure 10 – Mounting Guildines
Figure 11 – Roll sensor mounting with respect to sprayer orientation
4.5.1 Boom Roll Sensor Mounting
The boom roll sensor is the roll sensor with
the temperature probe attached to it (E03).
To mount the boom roll sensor refer to these
guidelines.
1. The boom roll sensor must be attached to
the center part of the boom.
2. Use cable-ties to secure the bracket to a
square edge feature (square tube).
The roll sensors must be
mounted with the Amp
connectors pointing to the
right

15
3. The AMP (circular) connector must be
pointing to the right hand wing (when
looking from the rear).
4. The ring terminal on the boom roll sensor
is a temperature probe and must be
attached to the side of the valve block
(Section 4.5.3).
Figure 12: Roll Sensor Mounting on Boom Frame

16
4.5.2 Chassis Roll Sensor Mounting
The chassis roll sensor must be attached to
the chassis of the sprayer. To mount the
chassis roll sensor, refer to the following
guidelines.
1. The chassis roll sensor does not have a
temperature probe (E04).
2. Cable-tie the bracket to a square edge
(square tube).
3. The AMP (circular) connector must exit
towards the right hand wing (when
looking from the rear).

4.5.3 Temperature probe
Fasten the temperature probe (E03) to the
UC4+ valve block using the included
3/8x1/2” bolt as illustrated in Figure 14.
