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 3
It is necessary to test the boom
functions in all directions

4.2 B OOM S PEED T EST
IMPORTANT:
Raise/lower all boom sections se eral times to
warm up the hydraulic system. Grease all
mo ing 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,
MAIN and ROLL functions
Your sprayer may not ha e 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

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)
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
A oid 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
