4 4.1 INSTALLATION PROCEDURE 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.

4.3 WING SENSOR INSTALLATION 1. Assemble the Breakaway Sensor Mounting Brackets (B11) as show in Figure 4 and Figure 5. 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.
(ahead) of the boom (see Figure 6 and Figure 8). General mounting rules for UC4+ ultrasonic wing sensors: 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). a) In its lowest position, the sensor mouth must be 9 inches or more from the ground. 5. Sensor cables should run through the mounting bracket tube and then behind the member the bracket is mounted onto.
Apply a light coating of the supplied Permatex Anti-seize grease to all threaded parts upon installation.
4.4 MAIN LIFT SENSOR INSTALLATION 1. Assemble the main lift sensor bracket (B11) as shown in Figure 10. 3. Mount the sensor onto the sensor mounting collar (Figure 11). Sensor Mounting Collar Bracket Tube Sensor Mounting Tab Bracket Base Figure 10: Main Lift Sensor Bracket 2. The bracket can then be mounted to the lowest frame member on the center section of the sprayer.
4.5 ROLL SENSOR INSTALLATION Before installing the roll sensors you must determine if your sprayer has a trapeze style or center pivot style boom. For installation on a trapeze style boom refer to Section 4.6. For installation on a center pivot boom refer to Section 4.7.
4.6 ROLL SENSOR INSTALLATION (TRAPEZE STYLE BOOMS) Mount the roll sensors to the included roll sensor brackets using the machine screws and nylon lock nuts. (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.
4.6.1 Boom Frame Roll Sensor Mounting 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.
4.6.2 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.
4.7 ROLL SENSOR INSTALLATION (CENTER PIVOT STYLE BOOMS) Mount the roll sensors to the included roll sensor brackets using the machine screws and nylon lock nuts. (Figure 19) The roll sensors must be mounted tightly to the brackets. When mounting the roll sensors use the following guidelines and refer to Figure 20. a) The smaller the distance between A and B in Figure 20, 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.
* The boom frame roll sensor does not have a temperature probe Figure 21: Roll Sensor Mounting with Respect to Sprayer Orientation 4.7.1 Boom Roll Sensor Mounting 4.7.2 Chassis Roll Sensor Mounting The boom roll sensor (E04) must be mounted to the rotating part of the boom. Follow these guidelines and refer to Figure 22 to mount the sensor. The chassis roll sensor must be mounted to a non-rotating part of the boom. To mount the chassis roll sensor, follow the following guidelines and refer to Figure 22.
E03 E04 Figure 22: Boom and Chassis Roll Sensors Correctly Mounted 4.8 INVERTED ROLL SENSOR MOUNTING If desired, the Roll sensor may be mounted inverted, so long as the connector exits towards the right-hand boom. Inverted mounting may be used to optimize the mounting criteria explained in Section 4.7. 4.9 TEMPERATURE PROBE Fasten the temperature probe (E03) to the UC4 valve block using the included 3/8x1/2” bolt as illustrated in Figure 23.
4.10 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: 3. Install the orifices (F01) into the "B" ports with the notch facing outward as shown in Figure 26. 4. Install the orifices (F01) into the "A" ports with the notch facing inward as shown in Figure 26. 5.
4.10.2 Valve Mounting 1. Mount the NORAC valve (V01) on the sprayer using the valve mounting bracket (B10). 2. As shown in Figure 27, 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.
4.10.3 Hydraulic Plumbing WARNING! From this point in the installation the booms will be inoperative until the electronics are fully installed. 1. 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. 2. Connect the NORAC supplied hoses (H03) to the Pressure (P) and Tank (T) ports on the NORAC valve block (V01). Route both of these lines to the sprayer valve block. 3.
4.11 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 (ROP). Four pilot holes for the screws provided need to be drilled to facilitate the control panel mounting.
2. On the right-hand side of the cab there is an electrical access panel. The tee connection on the UC4+ power cable (C10) must be connected between the 9-pin connector shown in Figure 31 and the electrical panel. panel (Figure 31). Use a multimeter to ensure you have selected the right wire. The light blue wire should have 12-Volts on it whenever one of the boom LIFT switches is operated. Use a tee electrical connector as shown (not provided) or solder and seal appropriately. 3.
10. The connectors on the valve cable (C03) are marked RIGHT UP, LEFT UP, RIGHT DOWN and LEFT DOWN. Cables labeled with UP go on the same side as the hydraulic hoses. Figure 32: Valve Cable Connections 11. Connect the CAN Node cable (C02B) to the 4-pin AMP plug on C11. 12. Route the CAN Node cable (C02B) to the roll sensors which are installed in Section 1.1. Follow existing cables and/or hydraulic lines. 13. Connect 4-pin AMP connectors on C02B to the sensors.
4.12 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. 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. If you still have trouble, contact NORAC for assistance.
