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. You will need a stopwatch or a watch that displays “seconds” for the next step. 1. Drive your sprayer onto a flat piece of land, with unobstructed boom movement (e.g. no power lines). 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”. 2.

4.3 WING SENSOR INSTALLATION 1. Mount the Low Profile Sensor Mounting Brackets (B20) onto the boom as show in Figure 4 and Figure 5 with the mounting base in front of the tube. 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. Mounting the sensor bracket to the break-away section of the boom may cause the boom to drop suddenly as a break-away occurs.
Rainflaps are only installed in the wing sensor brackets and are not installed for 120’ booms. 4. Insert one side of the rainflap rod into the pre-bent hinge tab on the sensor bracket. (Figure 6) 7. Ensure the rainflap actuates smoothly when the bracket is turned upside down and returns to the open position when the sensor bracket is returned to its operating position (sensor pointing downwards toward the ground). General Mounting Rules for Low Profile Brackets: A.
General Mounting Rules for UC4+ Ultrasonic Sensors: a) In its lowest position, the sensor must be 9 inches (23 cm) or more from the ground. b) Ensure that there are no obstructions within a 12-inch diameter circle projected directly below the center of the sensor. c) The sensor should be approximately vertical at normal operating heights.
Apply a light coating of the supplied Permatex Anti-seize grease to all threaded parts upon installation.
4.4 MAIN LIFT SENSOR INSTALLATION 1. Mount the bracket onto the lowest frame member on the center section of the sprayer. (Figure 13 and Figure 14). Figure 14: Main Lift Sensor Bracket Mounting Position (Side View) Figure 12: Main Lift Sensor Bracket Mounting The General Mounting Rules for Low Profile Brackets and the General Mounting Rules for UC4+ Ultrasonic Sensors, from the previous section, must be followed. 2. Mount the sensor into the bracket.
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 15. The roll sensors must be mounted tightly to the brackets. When mounting the roll sensors, use the following guidelines and refer to Figure 16. a) The smaller the distance between A and B in Figure 16, the better the performance will be. b) Ensure the roll sensors are sitting relatively level when the sprayer chassis and boom are level.
4.5.1 Boom Frame Mounting Roll Sensor 1. Use the supplied hardware to mount the boom frame roll sensor (E04) as shown in Figure 17. When mounting the boom frame roll sensor follow these guidelines: a) To prevent bending the bracket, ensure bolts are placed as close together as possible (minimize C in Figure 17). b) Be sure to use the roll sensor without the temperature probe (E04). c) When the boom is centered (not rolled over) the roll sensor should be level with respect to the sprayer chassis.
4.5.2 Chassis Roll Sensor Mounting 1. It is often best to cable tie the chassis roll sensor in place. When mounting the chassis roll sensor follow the guidelines and refer to Figure 18. The chassis roll sensor must be mounted on a portion of the sprayer that does not pivot and is as close to the boom frame roll sensor as possible (Figure 16). a) Make sure you are using the roll sensor with the temperature probe (E03). b) Ensure the roll sensor is level with respect to the chassis.
4.6 HYDRAULIC INSTALLATION WARNING! The hydraulic system creates very high pressure. Before disconnecting any hydraulic lines ensure all pressure has been bled from the system. When changing the boom hydraulic hoses leave the booms in TRANSPORT POSITION. IMPORTANT: Component failure due to oil contamination is not covered under the UC4+ Spray Height Control system warranty. It is recommended that a qualified technician does the hydraulic installation. 4.6.1 Valve Assembly 3.
4.6.2 Valve Mounting 1. Mount the NORAC valve (V01) on the sprayer using the valve mounting bracket (B10). 2. Screw short side of the threaded rods into the bottom of the valve block at least 3/8". The valve mounting holes are drilled and tapped 3/8 NC-1" deep. 3. Tighten the Hex nuts to hold the rods. 4. Put the mounting bracket on the other side of the tube and tighten with the spring washers and the Hex nuts. 5. Cut excess off of the rods, if necessary.
4.6.3 Hydraulic Plumbing WARNING! From this point in the installation the booms will be inoperative until the electronics are fully installed. After the NORAC valves are mounted, the hydraulic hoses and fittings can be plumbed. The plumbing for the hydraulic circuit is shown schematically in Figure 3. 1. Connect the four 90 degree fittings (F07) to the “A” and “B” ports on the NORAC valve block. Attach the four 6FORXR-6MOR tee fittings (F03) to the 90 degree fittings on the NORAC block. 2.
4.6.4 120’ Boom Orifice Installation If the kit is being installed onto a 120’ boom, it is recommended that an orifice be installed in each wing cylinder accumulator. This is not necessary for booms without accumulators. 1. Before continuing, make sure the booms are lowered all the way to the bottom of the cylinder travel. 2. Place one of the o-rings (F10) into the oring groove on the inline orifice (F11). 3.
4.7 ELECTRICAL INSTALLATION 1. Install the UC4+ Control Panel (E01) in the cab of the sprayer. Mount the panel where it will be clearly visible and within easy reach of the operator. ROP A good spot to mount the UC4+ control panel is on the right hand side of the cab to the Roll Over Protection Bar. Four pilot holes for the screws provided need to be drilled to facilitate the control panel mounting.
Figure 26: Cable Configurations: C10, C11 and C14 2. Connect the UC4+ power cable (C10) to the UC4+ control panel in the sprayer cab. Ensure both plugs (P16 and P4) are connected to the panel. 3. Connect the 3-pin AMP plug (P3) on C10 to the 3-pin AMP receptacle (R3) on the power pigtail interface cable (C14). Splice the pigtails on C14 into the existing wiring. Ensure the UC4 control panel’s power is OFF for the remaining installation (Bottom of switch pressed IN).
Figure 27: Cable Configurations: Rear of the Sprayer 6. Route C11 to the rear of the sprayer, in the vicinity of the valve block. 13. Route the free end of C18 to the existing main control valve block. 7. Connect the 3-pin tower (T3) on roll sense interface cable (C16) to the mating connector (S3) on C11. 14. Insert the 2-pin tees (R2C-P2C and R2D-P2D) of C18 between the matching main control valve connections. 8. Route the free end of cable C16 to the existing left and right boom control valve block.
IMPORTANT: Provide enough slack in all cables to account for the movement of the main section, parallel lift, and FOLDING boom movement. Figure 28: Valve Cable Connections 17. Connect the CAN Node cable (C02B) to the 4-pin AMP plug on C11 (Figure 29). 18. Route the CAN Node cable (C02B) to the roll sensors which are installed in Section 4.5. Follow existing cables and/or hydraulic lines. Figure 29: Cable Configurations: C11, C02 and C02B 19. Connect the 4-pin AMP connectors to the roll sensors. 20.
4.8 COMPLETING THE INSTALLATION 1. Start up your sprayer and test the sprayer’s functionality. The NORAC Control Panel does not need to be powered up for the original switches to function. Unfold the booms and raise/lower each boom and main section. Again confirm that the cabling/hoses are agreeable to the entire range of motion. 2. If any functions do not work, review the hydraulic and electrical portions of this manual to check for proper installation.
