on the sprayer.
oAll fold functions
oMain lift function
oWing tilt functions (if applicable)
oSlant function
4.2 EXISTING SYSTEM CHECK
oEnsure the boom suspension is configured as a short-pendulum (insert boom pin to
constrain the long-pendulum suspension)
oInspect boom suspension wear-pads for excessive wear
oSet the boom suspension to be critically damped (Figure 3). Adjust the boom springs and
dampers accordingly.
A) Unlock the boom, and push boom tip down approximately 75 cm (30 inches).
B) Hold the boom steady for a moment, and release.
C) Ensure the boom returns to its relaxed state as quickly as possible, with little to no
overshoot.
Figure 3: Boom Push Test- Critically Damped

4.3 WING SENSOR INSTALLATION
1. Assemble the breakaway sensor mounting Brackets (B11) as show in Figure 5.
Figure 5: Breakaway Sensor 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. Refer to the following sections for specific
details on mounting to different styles of booms.
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 in front of or behind
the mounting tube (the difference in mounting can be seen in Figure 7 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 13).
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
NOTICE: Avoid mounting sensors in locations where they may read from
parts of the boom as shown in Figure 7.

4.3.1 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.
Figure 8: Sensor Mounting Guidelines

4.3.2 Suggested Mounting Location for Wing Bracket on HSA Boom
Mounting the NORAC UC4 breakaway bracket to the HSA aluminum boom will require the
use of a RAU aluminum boom clamp, as illustrated below.
Figure 9: UC4 Sensor Bracket Mounted to Boom using RAU HSA Boom Clamp
Using this clamp will also require adjusting the width of the hole in the NORAC
bracket to accommodate the larger bolts and differences in dimensions
between the 2 parts.
For best performance, the sensor should be mounted 1-2m in from the boom tip. Depending
on the size of the boom, this may require putting the sensor on the breakaway bracket.
NOTE:
It may be necessary to create an adapter to mount the NORAC UC4+ bracket to
the RAU HSA boom. This bracket, when used in conjunction with the RAU HSA
boom clamp, will prevent the boom from rotating down towards the ground due to
the clamp slipping on the aluminum.

4.4.2 Cable Installation
Figure 15: Cable Routing Overview
1. Connect C10 to the UC4 control panel in the sprayer cab. Ensure that both plugs (P16A
and P4) are connected to the panel.
2. Route the receptacle end (R16) of C10 to the exterior of the cab and connect to C11 at
the hitch. Ensure cable is routed in a safe manner to avoid damage.
3. Connect Power to Harness C10 via the 3-pin AMP plug. If this plug does not fit a power
source in the tractor, cut off the connector and hard-wire to a power source. Ensure the
power source is fused (10A).
4. Install the sensor branch cable (C02) along the boom between the ultrasonic sensors. Be
sure to route the cable through the boom to avoid damage to the cable during field
operation or boom folding. Connect cable to cable C11.
5. Connect all sensors (E02) to C02 as indicated in figure 2. One connector of C02 will
remain unplugged.

4.5 COMPLETING THE INSTALLATION
1. Test the functionality of the original manufacturer’s boom controls. The NORAC
Control Panel (E01) does not need to be powered up for the original switches to
function. Unfold the booms and raise/lower each boom and main section. Confirm
that the cabling/hoses are agreeable to the entire range of motion. If one or more of
these functions do not work, review the hydraulic and electrical portions of this
manual to check for proper installation.
2. Unfold the booms and level to 90 cm (or 35 inch) nozzle height. At this point ensure
the UC4+ sensors are reading from an adequate and uniform target, such as gravel or
dirt, or concrete.
3. Begin the Automatic System Setup procedure as described in the UC4+ Sprayer
Boom Control Operator’s Manual (M01). Select the RA2 type.
4. When finished UC4 panel should display the Main Operating Screen:
M 90 M (example)
This indicates the system is ready for the second stage of installation. This will
require the manual calibration of the slant valve.
5. According to Figure 18 toggle "SETUP" until the display shows "More?". Toggle
"AUTO (YES)" to confirm. Toggle "SETUP" until the display shows "Roll?". Toggle
the "AUTO (YES)" switch to confirm. Toggle the "SETUP" switch to access the next
menu prompt or toggle "SENSOR DISPLAY" to access the previous menu.
