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 6.
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 7.
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 7,“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 7,
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 7.
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 7.
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).
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+ 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 (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
number on the right hand side
(Figure 9).

13
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.

3. Mount the sensor onto the sensor
mounting collar (Figure 11).

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 smaller the distance between A
and Bin Figure 14, the better the
performance will be.
Distance A can not be more than
12”.
b) The roll sensors must not be
mounted below the pivot point.
c) Ensure the roll sensors are sitting
relatively level when the sprayer
chassis and boom are level.
d) 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 15 – Roll Sensor Mounting with Respect to Sprayer Orientation
4.5.1 Boom Roll Sensor Mounting
The boom roll sensor (E04) must be
mounted to the rotating part of the boom.
Follow these guidelines and refer to
Figure 16 to mount the sensor.
a) Make sure you are using the roll
sensor that does NOT have a
temperature probe (only one cable)
(E04).
b) The boom roll sensor must be
mounted to the rotating part of the
boom suspension.
c) Use cable-ties to secure the bracket
to a square edge feature (square
tube).
d) Ensure the AMP (circular) connector
exits towards the Right Hand Wing
(when looking from the rear of the
sprayer).
e) Securely cable-tie the connector to
the frame.
4.5.2 Chassis Roll Sensor Mounting
The chassis roll sensor must be mounted
to a non-rotating part of the boom. To
mount the chassis roll sensor, follow the
following guidelines and refer to Figure
16.
a) Make sure you are mounting the roll
sensor that does have a temperature
probe (2 cables) (E03).
b) Mount the chassis roll sensor (E03)
to a non-rotating part of the boom.
c) Cable-tie the bracket to a square
edge feature (square tube).
d) The AMP (circular) connector
MUST exit towards the Right Hand
Wing (when looking from the rear).
e) Securely cable-tie the connector to
the frame.
* The boom frame
roll sensor does not
have a temperature
probe
