4 INSTALLATION PROCEDURE
4.1 E LECTRICAL I NSTALLATION
Install the UC4 control panel (Item E1) in the cab of the sprayer with the supplied
mounting bracket. Mount the panel where it will be clearly visible and within easy
reach of the operator. The location must facilitate connecting the power and sensor
cables to the bottom of the control panel.
Generally in the cab, a good spot to mount the UC4 control panel is on the right
hand side of the cab to the ROP (Roll Over Protection). Four pilot holes for the
screws provided would need to be drilled to facilitate the mounting of the control
panel.
In the Hagie STS12 cab, a good spot to mount the UC4 control panel is on the right
hand side of the cab, near the front window (Figure 4).
Figure 4 – Control Panel Mounting
1. Connect the UC4 power cable (Item C10) to the UC4 control panel (Item E1) in
the sprayer cab. The cable coming from the Hagie switch handle routes to the
console on the right side of the cab and connects through to the outside with a
24-pin connector. Insert the UC4 power cable between this connection.

9
2. Locate the small access holes in the floor of the cab. These holes should be
utilized to route cables from inside the cab to the exterior.
3. Route the free-hanging wires with ring terminals from the UC4 power cable
(Item C10) out the floor of the cab. Battery terminals are present under the cab
and may be used to provide power (white wire) and ground (black wire) to the
UC4 system (Figure 5).
Figure 5 – Power Connections
4. Connect the sensor trunk cable (Item C1) to the UC4 control panel (Item E1) in
the cab. Route the cable through the access hole and to the front of the sprayer.
Follow hydraulic lines or other electrical cables to route the trunk cable to the
midpoint of the center section at the front of the sprayer. Provide enough slack
to account for the movement of the center section and parallel lift.
5. Plug the six-pin GP connector on the power cable (Item C10) in to the valve
extension cable (Item C4). Route the cable through the access hole and to the
front of the sprayer ending at the area where the hydraulic valves are located.
Connect this end to the NORAC variable rate valve cable (Item C3).
NOTE: From this point of the installation until the hydraulics are fully
installed the booms will be inoperative.

4.2 H YDRAULIC I NSTALLATION
1. Install the fittings and orifices into the hydraulic valve. On a clean surface
remove the plastic plugs from the "A", "B", "P", "T" and "S" ports. Install the
6MB-6MJ (Item H51) fittings on the "P" and "T" ports and tighten to 18 ft-lbs
2. Install the orifices (Item H50) into the "A" and "B" ports as shown. Install the
"B" port orifices with the notch facing outwards and "A" port orifices with the
notch facing inward. Install the 6MB-6MJ fittings (Item H51) into the ports
and tighten to 18 ft-lbs.
Figure 6 – Valve Block Port Assembly
3. Remove the two bolts holding the Hagie valve block in place on the right side of
the center rack. Bolt the valve mounting plate (Item B10) supplied in this
location using the longer bolts (Item M11) in the kit (Figure 7). Figure 7
shows an installation using multiple valves your system may not be exactly as
shown.)

11
Figure 7 - Valve Mounting Location
WARNING:
The hydraulic system creates very high pressure that can injure. Before
disconnecting any hydraulic lines ensure that all pressure has been bled
from the system. When changing the boom hydraulic hoses leave the
booms in the transport position.
4. After the valves are mounted to the sprayer, the hydraulic hoses and fittings can
be installed (plumbed). The plumbing for the hydraulic circuit is shown
schematically in Figure 3. The “B” lines leading from the NORAC valve blocks
are the “raise” lines, and must be connected to the side of the cylinders which
raise the booms.
NOTE: You must ensure there are no other orifices present in the circuit
between the Norac valve block and the boom cylinders.
5. Install the valve cables (Item C3) onto each NORAC valve as shown in Figure
8. The connectors on the valve cable are marked to indicate the Left and Right
Boom as well as portside (Lower) and Raise directions. Ensure that the cables
are oriented as shown, with respect to the cylinder ports.

4.3 W ING S ENSOR I NSTALLATION
1. Assemble the Breakaway Sensor Mounting Brackets as show in Figure 9 and
Figure 10.
Figure 9 – Breakaway Sensor Bracket Exploded View
Figure 10 – Breakaway Sensor Mounting Bracket Assembly
a) Assemble the bolt and nut into the collar of the bracket.
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) Compress and install the spring between the collar and the upper ring of the
base.

14
e) Install the tube as shown and, for now, lightly tighten collar around the tube
you will need to aim the sensor bracket later.
NOTE: When installing the Sensors (Item E2) start with the smallest serial
number on the left hand side proceeding to the largest serial
number on the right hand side. This will allow a faster setup when
tuning the system.
Figure 11 – Sensor Serial Number Installation Location
2. Inspect the boom in the folded position and mark the locations where the Sensor
brackets can be mounted then unfold the booms and mount the sensors.
3. Mount one ultrasonic sensor (Item E2) near the tip of each boom with the
brackets provided (Item B13). Use the adapter plate (Item B16) to bolt to the
45 degree tube on the boom. Then attach B13 directly to B16 with the bolts
provided. Using the 8-mm nuts and lock washers provided with the sensor to
attach the sensor to the bracket. The sensors should be oriented forward (ahead)
of the boom. Ensure that the sensor and bracket will not interfere with
anything when the boom is folded for transport.
General requirements when mounting ultrasonic sensors.
1. When the boom is in its lowest position, the sensor mouth must be nine
inches or more from the ground.
2. The bottom of the sensor must be at least 9 inches in front the spray

15
nozzles.
3. The bottom of the sensor must be at least 9 inches above the spray
nozzles.
4. The sensor should be approximately vertical at normal operating
heights.
5. Insure that there are no obstructions within a six-inch diameter circle
projected directly below the center of the sensor.
Improved boom tip protection may be obtained by mounting the sensor as close
to the end of the boom as possible. If the sensors are mounted to the breakaway
portion of the boom, the operator must be aware that due to boom geometry a
breakaway action may cause the UC4 controller to force the boom closer to the
ground. Please refer to the UC4 system warranty at the end of the Operator’s
Manual (Item M1) for implications.
Figure 12 - Sensor Mounting
4. The sensor mounting brackets can be installed two basic ways. One with the
base behind the tube, which is preferred, or with the base mounting in front of
the tube. Both mountings are acceptable however the preferred mounting will
be less likely to damage the bracket in the event of a boom contacting a post or
obstruction.

16
Figure 13 – Preferred Mounting
Figure 14 – Another Acceptable Mounting
5. The sensor cable should be run down through the tube of the mounting bracket
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. (See
Figure 13 or Figure 14)

17
6. Once the sensor brackets are mounted to the boom you can make adjustments to
fine-tune you particular sprayer installation. You may wish to mount the
sensors starting at a small angle to allow for easier "breakaway". This will allow
the sensor to "breakaway" more easily if contact is made directly to the front of
the bracket. The following are typical reason for mounting the bracket at an
angle.
-If the bracket must make contact with another boom section when
folded.
-If you spray in fields with many obstructions, such as beehives.

4.4 M OUNTING THE C ENTER S ENSOR
1. Mount the third sensor on the center section with the bracket. Mount the sensor
so it is pointing ahead of the boom if possible (ensure you have clearance when
the center section is raised and lowered). You may mount this sensor pointing
behind the boom if necessary, but try to keep it ahead of the spray nozzles
(Figure 16).
Figure 16 – Third Sensor Mounting Locations
4.5 C OMPLETING THE I NSTALLATION
1. Route the sensor branch cable (Item C2) from each sensor back to the center
section where the trunk cable has been routed. Follow existing cables and/or
hydraulic lines along the boom to avoid interference problems when the boom is
folded. Cable-tie the branch cable every 12 inches.
2. Start up the sprayer and check to see that all the manual boom controls are
working with the original switches on the Hagie handle. The NORAC control
panel does not need to be powered up for the original switches to function. If one
or more of these functions do not work, review the hydraulic and electrical
portions of this manual to check for proper installation. Also refer to Section 4 of
this manual for the electrical pin-outs of the Norac cables. You can use this
information to try to pinpoint where the problem is occurring. If you still have
trouble contact Norac for more assistance.
