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+ 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).

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 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 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 approximately
in 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 ROLL SENSOR INSTALLATION
Mount the roll sensors to the included roll
sensor brackets using the machine screws
and nylon lock nuts. (Figure 14)
The roll sensors must be mounted
tightly to the brackets.
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 smaller the distance between Aand
Bin Figure 15, the better the
performance will be.
Distance A cannot 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).
