4 INSTALLATION PROCEDURE

4.1 DETERMINING THE STYLE OF INSTALLATION

In general, there are two styles of installation that can be done with the NORAC UC4+ Spray Height Control system System: Electrically Teed Installation and Hydraulically Teed Installation.

4.1.1 Electrically Teed Installation Electrically Teed Installation is the preferred style of installation. However, this style can be done only if the sprayer valve block has individual electrical wiring to control each boom function (e.g. left up, left down, right up, right down, main up, and main down).

Figure 2 – Electrical Wiring Applicable

for Electrically Teed Installation

Figure 3 and Figure 4 show the Electrically Teed installation in its general installation configuration.

6

Figure 3 – UC4+ BC Components: Electrically Teed Installation

If your valve connectors or cables appear different than shown, refer to Appendix A for more details.

7

Figure 4 – Hydraulic Components: Electrically Teed Installation

8

4.1.2 Hydraulically Teed Installation Hydraulically Teed Installation must be done if the sprayer valve block does NOT have individual electrical wiring to control each boom function. For example, your sprayer may have signal lines to select a boom (left, right and main) and separate electrical signals for the direction (up and down).

Figure 5 – Typical Electrical Wiring for which Hydraulically Teed Installation is

Required

For Hydraulically Teed Installation, MANUAL mode of the UC4+ Control System does not operate the same as with Electrically Teed Installation. Electrically

Teed Installation will allow the operator to trigger individual boom movements into MANUAL mode while maintaining AUTO mode for the other boom movements (e.g. left boom can be in MANUAL mode while right boom is still in AUTO mode). Hydraulically Teed Installation does not support this function. If the operator triggers any boom movement, the whole NORAC system will convert to MANUAL mode.

Hydraulically Teed Installation may also be done if the operator wants the existing sprayer valves, instead of the NORAC valves, to operate the booms when the NORAC system is in MANUAL mode.

Figure 6 and Figure 7 show the Hydraulically Teed Installation in its general installation configuration.

9

Figure 6 – UC4+ BC Components: Hydraulically Teed Installation

If your valve connectors or cables appear differently than shown, appear to Appendix A for more details.

4.2 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.

It is necessary to test the boom functions in all directions

Table 3 – Hydraulic System Function Check Sheet

LEFTMAINRIGHTROLL* N/A N/A

* Some sprayers may not have this function.

4.3 BOOM SPEED TEST

IMPORTANT :

Raise/lower all boom sections several times to warm up the hydraulic system. 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 4.

You will need a stopwatch or a watch that displays “seconds” for the next step.

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”.

4. Lower the LEFT boom from its extreme HIGH position to the BOTTOM of its travel. Record this time in Table 4, Trial #1, for “Left DOWN”.

Be careful when lowering the booms so they don’t hit the ground.

5. Similarly, record two more time trials (Trial #2 & #3) for the LEFT boom and record in Table 4

6. Repeat Steps 1 through 5 for the RIGHT, MAIN and ROLL functions.

Your sprayer may not have a roll feature.

7. Average the three trials recorded for each boom movement and record this calculation in the “Average Time” slot in Table 4.

8. These “Average Times” now represent how quickly your system can react to manual control. In Section 1.1, this procedure is repeated with the UC4+ Spray Height Control system installed for comparison and troubleshooting purposes.

4.4 WING SENSOR INSTALLATION

1. Assemble the Breakaway Sensor Mounting Brackets (B11) as show in Figure 8 and Figure 9.

Figure 8 – Breakaway Sensor Bracket Exploded View

Figure 9 – Breakaway Sensor Mounting Bracket 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.

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 behind (Figure 12) or in front of the tube (Figure 10).

It is advised to avoid mounting the sensor bracket to a breakaway portion of the boom because a breakaway action can cause the UC4+ Spray Height Control system to force a boom close to the ground.

Please refer to the UC4+ Spray Height Control system warranty at the end of the UC4+ Sprayer Boom Control Operator’s Manual (M01) for implications.

4. Mount the NORAC UC4+ ultrasonic sensor (E02) into the sensor brackets. The sensors should be oriented forward (ahead) of the boom (see Figure 10 and Figure 12).

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).

14

5. 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 10).

Figure 10 – Another Acceptable Mounting

Avoid mounting sensors in locations where they may read from parts of the boom as shown in Figure 11.

Figure 11 – Poor Mounting (Sensor reading off boom)

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.

4.6.1.1 Boom Frame Roll Sensor Mounting

1. Use the supplied hardware to mount the boom frame roll sensor (E04) as shown in Figure 19.

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 19).

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.

d) It is best to mount the roll sensor to the left hand trapeze link (when looking from the rear of the sprayer).

e) The roll sensor AMP (circular) connector MUST exit towards the right had wing (when looking from the rear of the sprayer).

Figure 19 - Boom frame roll sensor mounted to a trapeze link

2. Cable-tie the sensor connector to the frame with enough slack to allow the link to rotate.

Make sure the bracket does not collide with any parts of the sprayer when the boom rotates. Also ensure there is enough slack to allow the roll sensor to rotate.

20

4.6.1.2 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 20.

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 18).

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.

c) The AMP (circular) connector MUST exit towards the right hand wing.

d) Make sure the temperature probe is able to reach the side of the valve block.

Figure 20 - Chassis roll sensor mounting

2. Refer to Section 4.6.4 on page 23 for mounting the temperature probe.

4.7 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.

NORAC provides proportional hydraulic valves for sprayer boom applications. For the generic installation kit, the customer must supply all hoses and fittings required. The fittings (Item F07) on the NORAC valve block are #6 MB (male ORB) to #6 MJ (male JIC). You will need the mating female JIC fitting on your hoses. If an adapter is required, add it after the JIC portion of these fittings. For a typical hydraulic layout, refer to the installation instructions and Figure 4 and Figure 7.

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.

4.7.1 Valve Assembly 1. On a clean surface remove all plastic

plugs from the NORAC hydraulic Valve (V01) (Figure 26).

2. Install the 6MB-6MJ fittings (F07) on the "P" and "T" ports and tighten to 18 ft-lbs.

Figure 26 – NORAC Valve Block

4. At this point the sprayer hydraulic system must be identified as being single acting or dual acting.

4.7.1.1 Dual Acting Assembly

1. Install the orifices (F08) into the "B" ports with the notch facing outward as shown in Figure 27.

2. Install the orifices (F08) into the "A" ports with the notch facing inward as shown in Figure 27.

3. Install the 6MB-4MJ fittings (F07) into the "A" and "B" ports and tighten to 18 ft-lbs.

Figure 27 – Dual Acting Valve Block

25

4.7.1.2 Single Acting Assembly

1. Install the orifices (F08) into the “B” ports with the notch facing outward as shown in Figure 28.

2. Install the 6MB-6MJ fittings (F07) into the “B” ports and tighten to 18 ft-lbs.

3. Install the 6MBP plugs (F09) into the “A” ports and tighten to 18 ft-lbs.

Figure 28 – Single Acting Valve Block

4.7.2 Valve Mounting

1. Mount the NORAC valve (V01) on the sprayer using the valve mounting bracket (B10).

2. Thread a nut onto the short threads of each of the threaded studs.

3. As shown in Figure 29, screw the short side of the threaded rods into the bottom of the valve block and tighten the hex nuts tight to the valve block.

4. Place the valve block onto a frame member, with the studs extending to the other side of the member.

5. Slide the flat bar from the bracket over the studs and install a spring washer and

nut onto each of the studs to hold the plate in place.

6. Tighten the two nuts so the valve block is held on tight and cannot move.

7. Cut excess off of the rods, if necessary.

If you wish to use bolts, 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. The rule of thumb for bolt length is 1-1/2" longer than the tube size.

You must ensure no hydraulic components will interfere with any sprayer parts or be pulled tight at any time.

Figure 29 – Valve Mounting Location

4.7.3 Hydraulic Plumbing – Electrically Teed

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 4.

2. Tee in pressure (“P”) and tank (“T”) lines to the NORAC valve block.

3. The existing hoses that run to the boom tilt cylinders should be disconnected from the sprayer valve block and reconnected to the NORAC valve block.

a) The raise lines from the boom tilt cylinders must be connected to the “B” ports of the NORAC valve block. The ports on the sprayer block must then be plugged/capped.

b) If the sprayer is Dual Acting, the “A” ports of the NORAC block must be connected to the “lower” lines of the cylinders. The ports on the sprayer block must then be plugged/capped.

c) If the sprayer is Single Acting, the “A” ports on the NORAC block are plugged. The lower lines of the cylinders can remain attached to the sprayer valve block.

4.7.4 Hydraulic Plumbing – Hydraulically Teed

1. Follow Figure 7 to plumb the hydraulic components.

2. Tee in the pressure (“P”) and tank (“T”) lines to the NORAC valve block.

3. The existing hoses that run to the boom tilt cylinders should be disconnected from the sprayer valve block and teed into the NORAC valve block.

4. The “raise” lines from the boom tilt cylinders must be connected to the “B” ports of the NORAC valve block.

a) If the sprayer is Dual Acting, the “A” ports of the NORAC block must be connected to the “lower” lines of the cylinders.

b) If the sprayer is Single Acting, the “A” ports on the NORAC block are plugged. The “lower” lines can remain attached to the sprayer valve block.

27

ROP 4.8 ELECTRICAL INSTALLATION

While installing the electrical parts of the system you may need to refer to Section 5.

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.

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.

Another option is to purchase an adapter for the flexible panel mount that has a 3/8" NC threaded stud on the end to bolt through an existing mount. You can find these at your local outdoor store as a RAM mount part number RAM-B-236. (See http://www.ram-mount.com/)

11. Connect the CAN Node cable (C02B) to the 4-pin AMP plug on C11 (Figure 35).

12. Route the CAN Node cable (C02B) to the roll sensors. Follow existing cables and/or hydraulic lines.

13. Connect the sensor branch cable (C02) to the 4-pin AMP plug on C02B (Figure 35).

14. Route the sensor branch cable (C02) to the wing and main sensors. Follow existing cables and/or hydraulic lines along the boom.

15. Cable-tie the installed cables every 12 inches.

IMPORTANT :

Provide enough slack in all cables to account for the movement of the main section, parallel lift, and FOLDING boom movement.

4.8.1 Cable Installation: Electrically teed Installation

For Electrically Teed Installation, there are two different methods of cable installation to tee in to the sprayer’s control system. The first is teeing the NORAC system in to the sprayer’s wiring inside the cab (Section 4.8.1.1). The second is teeing the NORAC system in to the sprayer’s wiring at the valve block (Section 4.8.1.2). Choose one of the two methods, whichever is suitable for your sprayer.

1. Connect the 16-pin AMP plug (P16B) of C10 to R16 of C15

2. String the cable jacket of the pigtail (N15) on C15 (Figure 36).

3. Splice the wires (N15) of C15 into the existing wiring to tee into appropriate functions of the sprayer’s control system. The wire colors and functions

are shown below. Some wires may not be used for this installation. Before connecting the wire of N15, check each sprayer wire you will be splicing to.

4. Disconnect the electrical connections of the left/right boom tilt functions: Left Up, Left Down, Right Up and Right Down, from the sprayer’s existing valves.

4.9 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. If you still have trouble, contact NORAC for assistance.

3. Turn on the power for the UC4+ Control Panel using the switch on the side of its chassis.

4. Repeat the Boom Speed Test as described in Section 4.3 Boom Speed Test with the NORAC UC4+ Spray Height Control system installed. Record the results for comparison in Table 5.

5. The procedure for the installation of the UC4+ Spray Height Control system is now complete. Begin the AUTOMATIC SYSTEM SETUP procedure as described in the UC4+ Sprayer Boom Control Operator’s Manual (M01A).

6. For a pull type sprayer, there should be very little play at the hitch clevis for optimal performance of the UC4+ Spray Height Control system. The addition of polymer washers can help tighten up this connection (Figure 41).

6 APPENDIX A – VALVE CONNECTOR CHANGE

Starting in January 2009, NORAC is changing the connectors on the boom height control valve block. The new style valve block will have 2-pin Deutsch connectors on the coils. The previous models had Hirschman style connectors as shown in Error! Reference source not found. new style valve blocks and cabling look similar to Figure 42 and Figure 43. Your system may ship with either style valve block, both are functionally equivalent. The system will operate properly with either style of connector.
