installation configuration. Figure 2 – UC4 Boom Control Components

Before installing the NORAC UC4 Boom Control System to your sprayer, it is necessary to check that all functions of the existing hydraulic system are working properly. Furthermore, it is informative to determine how quickly your sprayer booms and main (center) section are able to change their position without the UC4 System installed. Doing so may illustrate the design strengths and constraints of your sprayer’s mechanical and hydraulic configuration. This information may also prove valuable when troubleshooting the installation, and if you need to contact NORAC for installation support. For example, NORAC support staff may use this information to determine if there are unwanted orifices (or backwards orifices) remaining in the hydraulic system when the UC4 System is installed. Drive your sprayer onto a flat piece of land, without any obstructions in the way of boom movement (e.g. power lines). Try to gain the best view of the booms and involved cylinders as you can. This may be best done with two people: one in the cab, and one outside. Perform following Function Check and Boom Speed Test. 4.1 EXISTING HYDRAULIC SYSTEM FUNCTION CHECK Check that all functions of the existing hydraulic system of your sprayer by using Table 2. There may be more functions in the existing hydraulic system. Please refer to the sprayer’s operation manual and ensure checking all functions. Table 2 – Hydraulic System Function Check Sheet HYDRAULIC SYSTEM FUNCTION INNER OUTER TIP* FIELD OPERATION FOLD UNFOLD FOLD UNFOLD FOLD UNFOLD UP DOWN LEFT BOOM RIGHT BOOM MAIN BOOM N/A N/A N/A N/A N/A N/A ROLL* N/A N/A N/A N/A N/A N/A * Some sprayers may not have this function/section.

IMPORTANT: Let the sprayer run for several minutes to heat up the hydraulic oil. Raise/lower the left and right booms, main and hydraulic roll sections several times to help get the system (hydraulic oil, valve solenoids) warmed up. This will simulate field conditions and makes QUITE a difference in some cases. Grease all moving 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 3. NOTE: You will need a stopwatch or a watch that displays “seconds” for the next step. 3. Individually raise the LEFT boom from its extreme LOW position to the very TOP of its travel. Note the length of time it takes for this and record this in Table 3, “Trial #1” for “Left UP”. 4. Individually lower the LEFT boom from its extreme HIGH position to the BOTTOM of its travel. Note the length of time it takes for this and record this in Table 3, Trial #1, for “Left DOWN”. NOTE: You will need to be careful when lowering the booms at full speed to the bottom of their travel so that they don’t hit the ground. You may want to mark positions on the cylinder pistons at which to stop the test while using another person as a spotter. Raising your main section will give you more working height to do this test. Please use common sense to avoid damage! 5. Similarly, record two more time trials (Trial #2 & #3) for the LEFT boom and record in Table 3. 6. Repeat Steps 3 through 5 for the RIGHT boom and the MAIN section. 7. Repeat a similar procedure for the hydraulic (active) roll feature (if your sprayer supports this) for the clockwise (CW) and counter-clockwise (CCW) rotations. 8. Average the times of the three trials recorded for each boom movement function (e.g. LEFT, RIGHT, etc.) and record this calculation in the appropriate “Average Time” slot in Table 3.

manual control of boom functions. In Section 4.7, this procedure is repeated with the UC4 System installed for comparison and troubleshooting purposes.

1. For reference, an exploded view of the Breakaway Sensor Mounting Brackets is as shown in Figure 4. Figure 4 – Breakaway Sensor Bracket Exploded View 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 for a more intuitive setup when tuning the system. This arrangement is also REQUIRED when using the “QUICK SETUP” feature available via the UC4 Panel software. This feature is typically used by NORAC technical support staff.

2. In order the to reduce the chance of problems, inspect the booms in their folded position. Mark the locations where the Sensor Brackets can be mounted without contacting the sprayer. Then the booms can be unfolded and the sensors mounted without having any mechanical interference. NOTE: If possible, mount the sensor brackets while the booms are in their folded position to reduce the chance of clearance errors and to ensure that the sensor and bracket will not interfere with anything when the boom is folded for transport. NOTE: Please note the maximum length of the Sensor Branch Cable (Item C2) for each branch. Note that the sensors will not be able to be mounted outside of this range on each boom and consider that some length will be taken up due to routing the cable. It might be wise to route the Sensor Branch Cable (Item C2) at this time to prevent problems. (See 4.6 Electrical Installation) IMPORTANT: Provide enough slack in the Sensor Branch Cable to account for the movement of the center section, parallel lift, and FOLDING boom movement.

brackets provided (Item B19). 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. General mounting rules for ultrasonic wing sensors: • When the boom is in its lowest position, the sensor mouth must be nine inches or more from the ground. • The bottom of the sensor must be at least 9 inches in front the spray nozzles. • The bottom of the sensor must be at least 9 inches above the spray nozzles. • The sensor should be approximately vertical at normal operating heights. • Insure that there are no obstructions within a 12-inch diameter circle projected directly below the center of the sensor. Improved boom tip protection and control may be obtained by mounting the sensor as close to the end of the boom as possible. However, 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 dangerously close to the ground. If your particular boom “breaks away” in an upward direction, the sensor may read a large height and force your boom to the ground when the system is in automatic mode. Please consider this situation when mounting wing sensors. If this is your case, you may want to avoid mounting on a breakaway section. Please refer to the UC4 system warranty at the end of the UC4 Sprayer Boom Control Operator’s Manual (Item M1) for implications.

Figure 7 – Cable Routing (Bracket shown is not the Nitro Bracket) 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 7).

fine-tune your 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 reasons 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. Figure 8 - Sensor Angular Adjustment 4.4 MAIN LIFT SENSOR INSTALLATION 1. Mount the third sensor on the center section with the bracket provided (Item B10). Ensure you have clearance when the center section is raised and lowered. Mount this sensor pointing behind the boom, but try to keep it ahead of the spray nozzles. (See Figure 9) 2. Aim the sensor perpendicular to the ground. Tighten all the sensor bracket bolts.

General mounting rules for ultrasonic main lift sensors: • The sensor must have a 12-inch diameter clear view of the ground without any obstructions. • The sensor is to be mounted as far outward from the center of the boom as possible. • Do not mount the sensor and target directly behind the tire. If mounted behind the tire there will be inadequate crop canopy to reflect the signal when using CROP mode. • Ensure that there will be no contact between the sensor and the booms when folding and unfolding. • Mount the sensor as low as possible while maintaining about 12-in or more above the target (i.e. The crop or the ground) and ensure that the sensor is safely high enough given the terrain and possible obstructions. NOTE: The standard kit will include an alignment fixture (Item M14). This fixture is NOT required when performing installations on sprayers that do not support boom roll movement. Discard or return M14 to NORAC.

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. 44..55..11 Valve Assembly (Single-acting cylinders) 1. On a clean surface remove the plastic plugs from the "A", "B", "P", and "T" ports of the Hydraulic Valve (Item V1). 2. Install the 6MB-6MJ (Item H51) fittings on the "P" and "T" ports and tighten to 18 ft-lbs. 3. Install the orifices (Item H50) into the “A” and “B” ports as shown. An O-ring pick can be used to ease installing the orifices into their locations. Install the "B" port orifices with the notch facing outwards and the “A” orifices with the notch facing inwards. 4. Install the 6MB-6MJ fittings (H51) into the “A” and "B" ports and tighten to 18 ft-lbs. 5. Install the 6FJCN caps (Item H18) on each “A” fitting and tighten to 18 ft-lbs. Figure 10 – Valve Block Port Assembly (Single-Acting Cylinders)

(Figure 10). If the number is “105723”, proceed to Section 4.5.2 (page 20). STEP 6 through STEP 13 are required for all other part numbers. 6. Assemble the Single Acting Sandwich Block Kit (Item H17). 7. Remove the 2 solenoid valves from the top of the valve block by removing the 4 Hex Socket Cap Screws from each valve and discard these 2-in long bolts. See Figure 11. 8. Coat the top and bottom of the sandwich block in clean hydraulic oil. 9. Install the 4 O-rings into the bottom of the sandwich block. 10. Place the sandwich onto the valve block with the O-rings facing downward. 11. Align the sandwich with the alignment holes. The "A" stamped into the sandwich faces the Port side of the valve block. See Figure 11. 12. Place the solenoid valves on top of each sandwich and install the 2-1/2" long bolts supplied with the sandwich. Tighten the bolts in a corner to corner pattern to 31 in- lbs. 13. Finish tightening the bolts in a circular pattern and torque the bolts to 62 in-lbs. Figure 11 – Sandwich Block Installation

1. A valve mounting plate (Item B10) is provided with 5/16” NC bolts. Mount the valve plate directly under the spray nozzle valves. (See Figure 12) Figure 12 – Mounting Plate and Valve installation NOTE: You must ensure the valve manifold, solenoids, and hoses will not interfere with any moving parts of the sprayer. Also, you must ensure proper routing of the hoses such that they will not be pulled tight at any time. 2. Mount the valve using the bolts (Item M11) and washers (Item M12) in the location shown in Figure 12. The bolts should thread into the valve block at least 3/8". The valve mounting holes are drilled and tapped 3/8 NC-1" deep.

44..55..33 Hydraulic Plumbing NOTE: After this point in the installation the booms will be inoperative until the electronics are fully installed. 1. After the NORAC 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. Follow the schematics for routing the hoses that connect to the cylinders. 2. Connect the two remaining hoses (Items H4 and H3) to the Pressure (P) and Tank (T) ports on the NORAC valve block (V1). Connect hoses H3 and H4 to the Nitro valve block using “T” fittings (Items H2 and H16) provided. See Figure 3.

circuit between the Norac valve block and the boom cylinders. 4.6 ELECTRICAL INSTALLATION 1. 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, a good spot to mount the UC4 control panel is on the right hand side of the cab to the ROP (Roll Over Protection) Bar. Four pilot holes for the screws provided need to be drilled to facilitate the mounting of the control panel. Figure 14 – Control Panel Mounting Figure 15 - Mounting the Control Panel with a Bracket

Connect the UC4 power cable (Item C10) between this connection. Connect the 3-pin power connector from the UC4 power cable to the power bar on the right hand side of the cab. Figure 16 – UC4 Joystick Connection 3. Connect the remaining 16-pin AMP connector to the UC4 Control Panel. 4. There is an access hole located in the front right corner of the cab floor that may be seen when the floor mat is lifted. Access plates (Items B16, B17 and B18) which maintain the cab seal are provided in the UC4 kit. Route the Sensor Trunk Cable (Item C1) through the smaller hole in the access plate and attach to the UC4 control panel mounted in the cab. 5. Using the Valve Extension Cable (Item C4), connect the 6 pin GP connector from the UC4 Power Cable (C10) to the 6 pin GP connector on the Valve Cable (C3) attached to the NORAC valves. When routing this cable use the larger hole in the access plate provided. The cover plates provided may now be screwed onto the access plate to seal the cab. If your sprayer has the quick disconnect option also install the Valve Disconnect cable (C11) between the Valve Cable (C3) and Valve Extension Cable (C4). This will allow for a connection to be made at the same location as the Nitro wiring.

6. Route the Valve Extension Cable (C4) and the Sensor Trunk Cable (C1) from the cab to the front of the sprayer to the area where the NORAC hydraulic valves are located. Use cable ties to fasten the Valve Extension and Sensor Trunk Cables to the sprayer. 7. Connect the UC4 Valve Cable (C3) to the Valve Extension Cable (C4) at the front of the sprayer. NOTE: The Valve Extension Cable (C4) may be packaged with one GP end not installed. This is normal; it helps installations for other sprayer types. Pin this connector on (connector included) as per drawing in section 5.4. TAKE EXTRA CARE! These pins require a special tool to remove them if you make an error! 8. Install the Valve Cable (C3) onto each NORAC valve as shown in Figure 13. The connectors on the valve cable are marked RIGHT UP, LEFT UP, RIGHT PORT (“right down”), and LEFT PORT (“left down”). Fasten with the included rubber seals and screws. Ensure that the cables are oriented as shown, with the cable labels RIGHT PORT and LEFT PORT on the SAME side as the hydraulic hoses (the “port-side” of the block). 9. Connect the Sensor Branch Cable (C2) to the Sensor Trunk Cable. If not done already, route the Sensor Branch Cable out to the wing sensors and center sensor and connect using the amp connectors. Follow existing cables and/or hydraulic lines along the boom to avoid movement problems when the boom is folded. Cable-tie the Sensor Branch Cable (C2) every 12 inches.

Cable to account for the movement of the center section, parallel lift, and FOLDING boom movement. 10. Start up your sprayer and test the functionality of the original manufacturer’s boom controls. 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 center section. Again confirm that the cabling/hoses are agreeable to the entire range of motion. 11. 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 5 in 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 assistance. 4.7 COMPLETING THE INSTALLATION 1. Turn on the power for the UC4 Control Panel using the switch on the side of its chassis. Ensure that the display lights up to confirm that the panel has proper +12 Volt power. 2. Repeat the Boom Speed Test as described in Section 4.2 Boom Speed Test with the NORAC UC4 System installed. Record the results for comparison in Table 4. 3. The procedure for the installation of the UC4 system is now complete. Begin the AUTOMATIC SYSTEM SETUP procedure as described in the UC4 Total Control Automatic Boom Height Technical Manual (M1A).

A word of caution is necessary when considering the mounting location for the center roll (OR main lift) sensor. Mounting the center roll sensor directly behind a sprayer tire can impair main lift control when spraying in CROP MODE. SOIL MODE performance will not be inhibited. Consider the following: when the sprayer tire travels over crop it will trample the crop into the ground to some degree. In this discussion, this crop depression is referred to as the “wheel track”. The NORAC Sprayer Boom Control System is designed to read the top of the crop when in CROP MODE. Figure 18 - Center Roll Sensor Mounted Behind a Tire Therefore when the roll sensor is in crop mode and positioned in the “wheel track”, there is insufficient amount of actual crop to measure. This would cause the main lift section to lower (when running in AUTOMATIC mode) because it will read off of the soil. This does NOT represent a control system deficiency, but unfortunately this could cause the center section to lower uncomfortably close to standing crop. "Wheel Track" Operation Normal Operation Figure 19 - Boom Behavior while in the “Wheel Track” There are four options: 1. Move the roll sensor to a new location that is outside of the “wheel track”. This is the preferred fix, but not always feasible.

lift manually. The wings will still adjust when in auto mode. 3. Adjust the “sensor offset” (for the center sensor) via the control panel in order to compensate for the height difference between soil and crop. 4. Add an additional sensor, away from the “wheel track”, to handle the main lift height measurement. 6.1 MOVING THE ROLL SENSOR This is self-explanatory. Try to mount the roll sensor in a location away from the wheel track while still allowing a 12-inch diameter clear view of the ground. 6.2 TURNING THE CENTER (MAIN LIFT SECTION) OFF This workaround will disable the center section’s AUTOMATIC control; manual control will still be possible. Manually set the height for the center section based on the crop height. The disadvantage is clear, AUTOMATIC center (main lift) control will be lost, but the right/left booms will still adjust automatically. Carry out the following procedure using the UC4 Control Panel: 1. Make sure you are in manual mode, at the operating screen. ↓↓↓↓35 MM 35 35 MM 35 35 MM 35 35 MM 35 2. Navigate to the "More ?" item in the SETUP menu. Press AUTO (YES). 3. Navigate to the "Main ?" item in the SETUP menu. Press AUTO (YES). 4. At the "Main On" prompt, toggle the +/- switch to change to “Main Off”. ↓↓↓↓Main Off Main Off Main Off Main Off 5. Press and hold SETUP for two seconds to return to the operational screen. 6.3 ADJUST THE SENSOR OFFSET To compensate for the lack of crop in the “wheel track”, adjust the main lift sensor’s height reading offset (Zero Height) so that the sensor will read higher to match the average height of your crop. Carry out the following procedure using the UC4 Control Panel: 1. Make sure you are in manual mode, at the operating screen. ↓↓↓↓35 MM 35 35 MM 35 35 MM 35 35 MM 35

(YES). 3. Navigate to the "Main ?" item in the SENSOR DISPLAY menu. Press AUTO (YES). 4. Toggle SENSOR DISPLAY to display the MLht menu item. ↓↓↓↓MLht 47 MLht 47 MLht 47 MLht 47 5. The “+” switch will increase the reading, the “–“ switch will decrease the reading. DECREASE the reading by the difference in height between standing crop and trampled crop in the “wheel track”. Adjust this until ALL three sections (right, left, main) are level in the field while in AUTOMATIC mode. This may take some experimentation in field conditions. 6. To return to the operating screen, press and hold SETUP for two seconds. Note that this is subject to a “trial and error” approach to getting this set adequately. The advantage is that AUTOMATIC control will be retained for the center section. Depending on the crop, the depression caused by the wheel might vary. Note that when turning the implement, the “wheel track” will follow a different path. If the roll sensor detects standing crop in this situation, the center section will lift momentarily. NOTE: The zero height (for the main lift sensor) will need to be reset when using SOIL MODE operation. 6.4 ADD AN ADDITIONAL SENSOR The final option would be to add a fourth sensor to your system to handle the main lift measuring duties. This sensor would need to be mounted on the center section such that it will NOT read in the wheel track. This would not be a reasonable option for those sprayer types that do NOT provide roll control. In these cases the kit includes a main lift sensor ONLY, and the sensor should be moved to a new location. NOTE: If you use this option, ensure that the roll sensor and the added sensor are located at least 36-in apart to avoid crosstalk.
