Rubber Track Operating Hints

Technical Manual



Do Not Allow Asphalt Build-up on Track

The following are some specific considerations for operation of asphalt pavers equipped with rubber tracks. While not all-inclusive, following these recommendations should reduce the risk of problems and improve rubber track durability and reliability.

During paving, asphalt sometimes flows down to the rear drive wheel and become packed between the track and wheel. This may cause the following problems: •

Oil in the asphalt will cause the rubber in the track to soften and reduce the durability.

•

Aggregate will abrade the rubber in the track and shorten its life.

•

Asphalt material build-up in the undercarriage will cause additional tension on the track.

Asphalt Build-up May Cause........

Guide Crush

Material retaining plates retracted will allow material to carry back around to tracks.

Guide Wear

Extend plates to prevent this.

Inner Rubber Wear

Figure 1 Asphalt on Track & Wear 22762 (12/04)

Technical Manual

Rubber Track Operating Hints Proper Installation of Material Retaining Plates Machines are shipped with the material retaining plates as shown in (Figure 2). To work properly, the plates must have the bottom edge of the plate below the bottom edge of the machine frame bulkhead and be extended.

Before paving begins, loosen nuts, slide plate out from frame and re-tighten nuts to hold plate in position. (Figure 3)

Material retaining plates repositioned.

Technical Manual

Rubber Track Operating Hints Maneuvering On Hot Asphalt Pavers are not normally operated on newly paved hot asphalt as it will damage the surface of the mat. There may however be certain conditions when this becomes unavoidable. If it is necessary to drive on newly paved asphalt, be aware this could be problematic.

Technical Manual

Rubber Track Operating Hints Generally, “de-tracking” occurs when the paver turns. If rubbing marks are noted on track frame, check track inner surfaces for signs of scarring caused by temporary de-tracking. To avoid “detracking”, it is recommended: •

Do not turn on or near hot asphalt. Move to a cold area and turn there. If turning on the hot asphalt is necessary, use forward as much as permissible and keep the turn gradual in as large an arc as possible. Maneuvering should be done at as slow a speed as possible.

•

Do not park on hot asphalt. High temperature can deteriorate the track rubber. It is recommended to remain on the hot area of asphalt no longer than twenty (20) minutes. Figure 5 Do Not Park On Hot Asphalt

22762 (12/04)

Technical Manual

Rubber Track Operating Hints Maneuvering On Uneven Surface

Caution - If a turn is attempted on an edge, track damage or “de-tracking” could occur.

Uneven terrain such as curbs, concrete ridges or joints of paved and unpaved surfaces (step in elevation) may affect machine maneuverability. One concern is the stress concentration caused by the sharp edges of the surface and another is when a track is parallel to an edge. (Figure 6)

Paver Edge of Mat Manhole

Figure 6 Steps in Elevation & Uneven Surfaces

•

Do not turn on or near sharp edges of uneven surfaces. It is best to make a turn while on an even surface. If a turn is made with a portion of the track on an edge or the track comes into contact with an edge during the turn, it could cause a cut, tear, or even “detracking”. If this situation is unavoidable, keep the turn gradual in as large an arc as possible, at slow speed, in forward and with a spotter to watch the track safety.

22762 (12/04)

•

Do not approach a step in elevation at a sharp angle. If it is necessary to move from one level of elevation to another, it is recommended the approach angle should be more than 45 degrees. The best method is to go perpendicular to it.

•

Do not park on a step in elevation. When parking, make sure the tracks are not resting on an edge or any sharp object. This may cause damage to the track. Rubber Track Operating Hints

Technical Manual

Rubber Track Operating Hints Maintenance of Track

•

To maintain and preserve the life of the rubber track it is important to follow these recommendations: •

Do not use solvents to wash the rubber track. Solvents including kerosene, gasoline, diesel fuel, or oils cannot be used to wash the surface of track rubber. The track rubber absorbs these solvents and will gradually soften and reduce its durability. Soap and water are recommended for cleaning the rubber track.

Covering track for long term outdoor storage. Rubber is affected by exposure to sunlight (ozone). Covering the track with something like a vinyl sheet if the machine is idle for an extended length of time, such as over Winter, will help keep the surface in good condition. This is especially true where the rubber is bent and stretched around wheels.

NOTICE If you scrape the rubber track surface to clean it, be careful to not damage or cut it when cleaning. Figure 8 Cover Track for Outdoor Storage

22762 (12/04)

Technical Manual

Rubber Track Operating Hints •

Releasing track tension for long term storage. As is true for covering the track, releasing the track tension when the machine is idle for an extended length of time, such as over Winter, will prolong its life.

Rubber Track Operating Hints •

4) Periodically check that any steel cable or ply cord are not exposed.

Check track alignment. Rubber track undercarriage component alignment is very important to the life of the track. An easy, quick check is to inspect the track center lugs. (Figure 11) If one side is worn more than the other side, one or more of the following conditions could exist. Factors such as asphalt build-up on the track inner surface, road crown, track tensioning, etc. If any of the above is present, correct the situation before excessive track wear occurs.

5) Periodically check that track is properly tensioned. A loose track could cause detracking. (Refer to Tension information in the Operation and Maintenance Manual.

Guide Lug Wear on One Side

Steering Grayhound Rubber Tire Pavers STEERING WHEELS DRIFT APART It is normal for the wheel to drift apart over a period of time. To get them back in unison, steer against limits in either direction. If the wheels drift apart quickly, preform checks listed above. The cause is usually leaking piston packing on one or both steering cylinders. STEERING CYLINDER TEST With the steering cylinders at mid stroke, remove the rod end hoses. Cap the rod end ports of the cylinders and plug the hoses. Turn the steering wheel to the left. If the right steering cylinder rod starts to move outward the the packing of the right cylinder may be bad and need to be replaced, or the inner wall of the cylinder tube has a scratch or gouge in it, allowing the hydraulic fluid to go around the packing. Remove the cylinder and replace it. Turn the steering wheel to the right. If the left steering cylinder rod starts to move outward then the packing of the left cylinder may be bad and need to be replaced, or the inner wall of the cylinder tube has a scratch or gouge in it, allowing the hydraulic fluid to go around the packing. Remove the cylinder and replace it. Always remember to flush the hydraulic steering circuit before replacing the hoses onto the cylinders. This is done by coupling the hoses of each cylinder together and turning the steering wheel in one direction for several rotations and then in the other direction for several rotations.

Track Tension Steel Track Pavers Tensioning Track

The track is designed to be virtually maintenance free. Proper cleaning and lubrication at the end of each paving day will maintain trouble free operation. However, neglect of the tracks can be expensive. Every time paver is cleaned, the track pins should be sprayed with light oil to lubricate them preventing them from rusting and binding.

If the track looks like it may be getting loose, it can be tested by placing a board or straight edge on the track between the front idler and the first top roller. If the gap between the bottom of the board and the top edge of the track is greater than 3¦4", the track tension must be adjusted. (Figure 2)

The Grayhound track paver uses a tension cylinder mounted above the final drive that maintains a constant volume of pressurized oil to the track adjusting cylinders. When the track encounters an obstacle, the system allows the tensioning idler to recoil rather than stretch or break the track. When the obstacle is cleared the system returns to the previous track tension adjustment.

3/4"

Figure 2 - Checking Track Tension

Important: Perform track tension checks and adjustments when the paver is at running temperature. Adjusting track tension when the paver is cold could lead to over-tensioning of the track.

1 3

Adjust track tension as follows:

4 5 From traction S charge pump

1) Start the engine.

T

2) Open the needle valve slowly to allow the track to retension. (Figure 4)

2

3) Drive the paver forward and backward slowly.

4 - Needle valve 1 - Counterbalance valve 2 - Rodless piston cylinder 5 - Idler tension cylinders 3 - Tensioning cylinder assy.

Warning: Be very careful when reaching over the moving track. Keep feet and loose clothing away from the moving track and rollers.

Figure 1 - Track tension hydraulic circuit

The track tensioning cylinder assembly consists of a cylinder with a rodless piston, a needle valve, and a counterbalance valve. (Figure 1) The piston keeps the oil from the idler tensioning cylinders separated from the main oil supply. When the track encounters an obstacle, it forces oil from the idler cylinders into the bottom side of the rodless cylinder. When the obstruction is cleared, pressurized oil from the traction charge pump forces the tensioning cylinder down which forces idler cylinders to move back to original position.

4) Stop the paver and close needle valve. 5) A properly tensioned track should have a 3¦8" to 1 ¦2" gap between a straightedge and the track. (Figure 3) 3/8" to 1/2"

Figure 3 - Proper Track Tension

The needle valve is used during track tensioning to bring the volume of oil on the bottom side of the rodless cylinder back to the proper level. The counterbalance valve allows oil to flow freely from the top side of the rodless cylinder to the tank when the track encounters an obstacle. 300 Series & CR411 Hydraulic Troubleshooting

Track Tension Steel Track Pavers Warning: Overtightening the track can cause serious damage to the track, idler or drive.

7) If oil continues to flow into the bucket, the tension cylinder piston or needle valve is leaking and must be repaired.

Track over-pressurizing

8) Turn the engine off and reconnect the hydraulic line to the "T" port.

If the track adjusting system is over-pressurizing during operation, the following procedure must be performed. It is a good idea to perform this check once each season to verify the tensioning cylinder is in good condition.

Track Relief Pressure In addition to adjusting the track tension, the track relief pressure should be checked at least once each season. Check track relief pressure as follows:

Notice: Do not run the paver while the system is over-pressurized. Running with an overpressurized system could damage the track and sprockets.

1) Perform "Track over-pressurizing" procedure above. 2) Stop engine.

Figure 4 - Bottoming Tension Cylinder

1) Disconnect the line from the "T" port on the track tension cylinder. Install a plug into the disconnected line. (Figure 4)


2) Attach a drain line to the "T" port and run the other end into a bucket.

6) Install a 3000 PSI gauge on the hose which is connected to the tension cylinder test port.

3) Close the needle valve by rotating clockwise. 4) Start the engine and run at full throttle.

7) Connect a hand operated hydraulic pump to the "T" port on the tension cylinder.

5) If the track was tensioned properly, no oil will flow into the bucket.

8) Start and run engine at full throttle.

6) If only a small amount of oil drains into the bucket, the tension cylinder piston and needle valve are working properly and track will tension properly. 300 Series & CR411 Hydraulic Troubleshooting

Track Tension Steel Track Pavers 9) Pump the hand pump to apply pressure to the counter balance valve. The counter balance valve will relieve the pressure generated by the pump at the track relief pressure setting. Note the pressure on the gauge when the counter balance valve relieves. 10) The track relief pressure setting should be 2050 psi +/- 100 psi. If pressure is outside this range, the counter balance valve requires adjustment. 11) To adjust track relief pressure: a) Loosen jam nut on counter balance valve. b) Rotate the valve counterclockwise to increase the pressure setting. Clockwise rotation will decrease the pressure setting. c) Tighten jam nut. 12) If the pressure can not be set, the counter balance valve is defective and must be replaced. Note - Replacement counter balance valves are factory set and should not require adjustment.

Rubber Track Hydraulic System


When the paver is started, oil is directed from the auxiliary pump to the track tension valves at 2500 psi. When tension pressure needs to be adjusted, oil is then routed to the piston side of the track tension cylinders by opening the tension valve charge cartridge needle valves allowing oil pressure to rise to 2500 psi. An accumulator for each track is placed in the circuit between the tension valve and the piston side of the track tensioning cylinders. The accumulator is pre-charged with dry nitrogen at 2250 psi to allow the track tension cylinders to retract and return if an impact is encountered.

The rubber track hydraulic system, see schematic, provides pressurized oil to the piston ends of track tension cylinders. Each track is independent and supplied by the auxiliary pump. Pressurized oil is held in the piston end of each track tension cylinder between tension valves and tension cylinders.

8) The gauge reading at the point where it drops quickly to 0 psi should be 2250 psi at 68 degrees F. This reading may be slightly more or less depending the ambient temperature and the hydraulic system temperature.

Checking Rubber Track Hydraulic System The rubber track hydraulic system contains components which will automatically maintain track tension. To check out the system, follow the steps below:

9) If the accumulator dry nitrogen pre-charge is at 2250 psi, then tighten the discharge needle valve screw by turning it clockwise until snug on its seat.

Auxiliary System Pump Pressure First check the auxiliary pump pressure compensator adjustment to be sure the system is set to 2500 +/100 psi. See tractor O&M Manual for this procedure.

10) Re-tighten jam nut on discharge cartridge. 11) Charge the tension circuit to 2500 psi as described below.

Track Tension Accumulator

12) If the pressure is below 2250 psi when it drops quickly to 0 psi, re-charge the accumulator with dry nitrogen.

Check pre-charge of track tension accumulators on each side. 1) Install pressure gauge (3000 psi) at test port marked G on the Track Tension Valve. 2) Start and run engine at full throttle. 3) Pressure should read 2500 psi. 4) Shut engine off. Pressure on gauge should not change. 5) Loosen jam nut on discharge cartridge of track tension valve. 6) Insert an allen wrench into the adjusting screw, slowly turn it counter-clockwise to open the discharge needle valve and release hydraulic pressure while carefully watching the gauge. 7) The pressure reading should drop off slowly until it reaches the accumulator dry nitrogen precharge pressure. When the pressure reaches the accumulator pre-charge point, the gauge will drop quickly to 0 psi.


13) If pressure is above 2250 psi, bleed off some dry nitrogen from the accumulator. 14) If the pressure drops steadily all the way to 0 psi and re-charging the accumulator does not work, then replace the accumulator.

Track Tension Pressure Check the track tension pressure on each side. 1) Install pressure gauge (3000 psi) at test port marked G on the Track Tension Valve. 2) Pressure should read 2500 psi.

1) Start and run engine at full throttle. 2) Loosen jam nut on charge cartridge of track tension valve. 3) Insert an allen wrench into the adjusting screw, slowly turn it counter-clockwise to open the charge needle valve and allow hydraulic pressure to build to 2500 psi while carefully watching the gauge. 4) When the gauge reaches 2500 psi, close the charge needle valve by turning it clockwise until snug on its seat. 5) Shut off engine and note pressure.

1) Remove and cap lines from auxiliary pump-totension valve and from tension valve-to-tank. Caution: Escaping fluid under pressure can penetrate the skin causing serious injury. Be very careful when disconnecting hydraulic or other lines. Search for leaks with a piece of cardboard. Protect hands and body from high pressure fluids. Any fluid injected into the skin must be removed immediately by a doctor.

Pressure should hold at 2500 psi. Track Tension Valve Cartridges & Track Tension Cylinder If the track tension cylinder bounces during operation as if there is air in the lines, do the following: 1) Loosen jam nuts on both charge and discharge cartridges of track tension valve. 2) Start and run engine at full throttle. 3) Insert an allen wrench into the adjusting screws on the needle valves. 4) Alternately open and close each needle valve. Start with the discharge and then the charge. 5) Do step 4 until air is eliminated. 6) Tighten both needle valves snug on their seats. 7) Tighten jam nuts on each needle valve. 8) Shut off engine and note pressure.

Protect hands and body from high pressure fluids. Any fluid injected into the skin must be removed immediately by a doctor.

3) If pressure drops from 2500 psi, observe which tension valve cartridge port (charge or discharge) is leaking hydraulic fluid. 4) Verify that both tension valve cartridge needle valves are completely shut as described above. 5) If one of the cartridge ports leaks, replace that cartridge. 6) If none of the cartridge ports is leaking, but the pressure still drops off, check the breather on the track tension cylinder.

DRIVE MOTOR

>> CASE DRAIN >>

FRONT WHEEL ASSIST (P4) The front wheel assist system should not be confused with or considered as a four wheel drive system. When the front wheel assist solenoid valve is energized pressure is applied to separate 5 way valves. When the 5way valves are open, pressure from the main traction pump is applied to both the main drive motor and the front wheel assist motor on that side of the machine. The amount of tractive effort increase will depend on the amount of traction the front wheels have in a given ground condition. FRONT WHEEL ASSIST WILL NOT ENGAGE Engine at FULL THROTTLE. Travel/P2/P4 switch to P4. Check front wheel assist solenoid valve DIN connector for light. If NO light, refer to electrical troubleshooting. If light is ON, (1) Refer to electrical troubleshooting for ground connection (2) Install a 600 psi gauge in the LH conveyor high pressure test port. (Do not engage conveyor) Refer to conveyor charge pressure above for pressure required. If pressure is low, refer to conveyor. (3) If pressure is correct, install 600 psi gauge between A port and hose going to the 5 way valves. If no or low pressure, defective solenoid valve. (4) If pressure is correct, install 6000 psi gage between 5-way valve and motor. Move machine. If very low or no pressure, defective 5-way valve on that side. Both sides will need to be checked. 300 Series & CR411 Hydraulic Troubleshooting

Steering Grayhound Rubber Tire Pavers STEERING WHEELS DRIFT APART It is normal for the wheel to drift apart over a period of time. To get them back in unison, steer against limits in either direction. If the wheels drift apart quickly, preform checks listed above. The cause is usually leaking piston packing on one or both steering cylinders. STEERING CYLINDER TEST With the steering cylinders at mid-stroke, remove the rod end hoses. Cap the rod end ports of the cylinders and plug the hoses. Turn the steering wheel to the left. If the right steering cylinder rod starts to move outward then the packing of the right cylinder may be bad and need to be replaced, or the inner wall of the cylinder tube has a scratch or gouge in it, allowing the hydraulic fluid to go around the packing. Remove the cylinder and replace it. Turn the steering wheel to the right. If the left steering cylinder rod starts to move outward, then the packing of the left steering cylinder may be bad and need to be replaced, or the inner wall of the cylinder tube has a scratch or gouge in it, allowing the hydraulic fluid to go around the packing. Remove the cylinder and replace it. Always remember to flush the hydraulic steering circuit before replacing the hoses onto the cylinders. This is done by coupling the hoses of each cylinder together and turning the steering wheel in one direction for several rotations, and then in the other direction for several rotations.

Track Tension Steel Track Pavers Tensioning Track

The track is designed to be virtually maintenance free. Proper cleaning and lubrication at the end of each paving day will maintain trouble free operation. However, neglect of the tracks can be expensive. Every time paver is cleaned, the track pins should be sprayed with light oil to lubricate them preventing them from rusting and binding.

If the track looks like it may be getting loose, it can be tested by placing a board or straight edge on the track between the front idler and the first top roller. If the gap between the bottom of the board and the top edge of the track is greater than 3¦4", the track tension must be adjusted. (Figure 2)

The Grayhound track paver uses a tension cylinder mounted above the final drive that maintains a constant volume of pressurized oil to the track adjusting cylinders. When the track encounters an obstacle, the system allows the tensioning idler to recoil rather than stretch or break the track. When the obstacle is cleared the system returns to the previous track tension adjustment.

3/4"

Figure 2 - Checking Track Tension

Important: Perform track tension checks and adjustments when the paver is at running temperature. Adjusting track tension when the paver is cold could lead to over-tensioning of the track.

1 3

Adjust track tension as follows:

4 5 From traction S charge pump

1) Start the engine.

T

2) Open the needle valve slowly to allow the track to retension. (Figure 4)

2

3) Drive the paver forward and backward slowly.

4 - Needle valve 1 - Counterbalance valve 2 - Rodless piston cylinder 5 - Idler tension cylinders 3 - Tensioning cylinder assy.

Warning: Be very careful when reaching over the moving track. Keep feet and loose clothing away from the moving track and rollers.

Figure 1 - Track tension hydraulic circuit

The track tensioning cylinder assembly consists of a cylinder with a rodless piston, a needle valve, and a counterbalance valve. (Figure 1) The piston keeps the oil from the idler tensioning cylinders separated from the main oil supply. When the track encounters an obstacle, it forces oil from the idler cylinders into the bottom side of the rodless cylinder. When the obstruction is cleared, pressurized oil from the traction charge pump forces the tensioning cylinder down which forces idler cylinders to move back to original position.

4) Stop the paver and close needle valve. 5) A properly tensioned track should have a 3¦8" to 1 ¦2" gap between a straightedge and the track. (Figure 3) 3/8" to 1/2"

Figure 3 - Proper Track Tension

The needle valve is used during track tensioning to bring the volume of oil on the bottom side of the rodless cylinder back to the proper level. The counterbalance valve allows oil to flow freely from the top side of the rodless cylinder to the tank when the track encounters an obstacle. 400 & 500 Series Hydraulic Troubleshooting

Warning: Overtightening the track can cause serious damage to the track, idler or drive.

Track Tension Steel Track Pavers Track over-pressurizing

8) Turn the engine off and reconnect the hydraulic line to the "T" port.

If the track adjusting system is over-pressurizing during operation, the following procedure must be performed. It is a good idea to perform this check once each season to verify the tensioning cylinder is in good condition.

Track Relief Pressure In addition to adjusting the track tension, the track relief pressure should be checked at least once each season. Check track relief pressure as follows:

Notice: Do not run the paver while the system is over-pressurized. Running with an overpressurized system could damage the track and sprockets.

1) Perform "Track over-pressurizing" procedure above. 2) Stop engine.

3) Close needle valve. 4) Bleed off pressure on tension cylinder by installing pressure gauge hose only onto test port and draining fluid into a bucket.

Figure 4 - Bottoming Tension Cylinder



2) Attach a drain line to the "T" port and run the other end into a bucket.

6) Install a 3000 PSI gauge on the hose which is connected to the tension cylinder test port.

3) Close the needle valve by rotating clockwise. 4) Start the engine and run at full throttle.

7) Connect a hand operated hydraulic pump to the "T" port on the tension cylinder.

5) If the track was tensioned properly, no oil will flow into the bucket.


6) If only a small amount of oil drains into the bucket, the tension cylinder piston and needle valve are working properly and track will tension properly.

9) Pump the hand pump to apply pressure to the counter balance valve. The counter balance valve will relieve the pressure generated by the pump at the track relief pressure setting. Note the pressure on the gauge when the counter balance valve relieves.

7) If oil continues to flow into the bucket, the tension cylinder piston or needle valve is leaking and must be repaired. 400 & 500 Series Hydraulic Troubleshooting

If pressure is outside this range, the counter balance valve requires adjustment. 11) To adjust track relief pressure: a) Loosen jam nut on counter balance valve. b) Rotate the valve counterclockwise to increase the pressure setting. Clockwise rotation will decrease the pressure setting. c) Tighten jam nut. 12) If the pressure can not be set, the counter balance valve is defective and must be replaced. Note - Replacement counter balance valves are factory set and should not require adjustment.

Track Tension Rubber Track Pavers

Rubber Track Hydraulic System The rubber track hydraulic system maintains a constant volume of pressurized oil to the piston ends of track tension cylinders. Each track is independent and supplied by the auxiliary pump.

When the paver is started, oil is directed from the auxiliary pump to the pressure reducing valves. Oil pressure is reduced from 2500 psi to 1900 psi and directed on to the take-up valves where two separate sections, a charging/isolation cartridge and a direction sensing cartridge, route the oil to the track tension shut-off valves connected to the track tensioning cylinders. A check valve and accumulator for each track are placed between the take-up valve charging/isolation cartridge and the piston side of the track tension shut-off valve. The accumulator is pre-charged with dry nitrogen at 1800 psi to allow the track tensioning cylinders to retract and return if a severe impact is encountered.

7) The pressure reading should drop off slowly until it reaches the accumulator dry nitrogen precharge pressure. When the pressure reaches the pre-charge point, the gauge will drop quickly to 0 psi.

Figure 9 - Track Tension Accumulator

Track Tension Check Valve and Shut-off Valve

8) The gauge reading at the point where it drops quickly to 0 psi should be 1800 psi at 68 degrees F. This reading may be slightly more or less depending the ambient temperature and the hydraulic system temperature.

Check the operation of the check valve and shut-off valve on each side.

9) If the accumulator dry nitrogen pre-charge is at 1800 psi, then tighten the shut-off valve screw by turning it clockwise until snug on its seat.


10) Re-tighten jam nut on shut-off valve cartridge.

4) Shut off the engine.

1) Install pressure gauge (3000 psi) at test port marked BTM on the shut-off valve.

3) Pressure should read 1900 to 2200 psi.

6) With the engine off, the pressure on the BTM port should hold at 1900 psi.

Track Tensioning Valve Cartridge Assembly

7) If the pressure bleeds off, check the shut-off valve as described above. 8) The take-up valve charges the BTM port side of the track tension cylinders each time the brakes are applied. To check this operation: 9) Start and run engine at full throttle. 10) Place your hand on the hose running to the check valve. Figure 12 - Track Take-up Valve

FRONT WHEEL ASSIST (P4) The front wheel assist system should not be confused with or considered as a four wheel drive system. When the front wheel assist solenoid valve is energized pressure is applied to separate 5 way valves. When the 5-way valves are open, pressure from the main traction pump is applied to both the main drive motor and the front wheel assist motor on that side of the machine. The amount of tractive effort increase will depend on the amount of traction the front wheels have in a given ground condition. FRONT WHEEL ASSIST WILL NOT ENGAGE Engine at FULL THROTTLE. Travel/P2/P4 switch to P4. Check front wheel assist solenoid valve DIN connector for light. If NO light, refer to electrical troubleshooting. If light is ON, (1) Refer to electrical troubleshooting for ground connection (2) Install a 600 psi gauge in the LH conveyor high pressure test port. (Do Not engage conveyor) Refer to conveyor charge pressure above for pressure required. If pressure is low, refer to conveyor. (3) If pressure is correct, install 600 psi gauge between A port and hose going to the 5 way valves. If no or low pressure, defective solenoid valve. (4) If pressure is correct, install 6000 psi gage between 5-way valve and motor. Move machine. If very low or no pressure, defective 5-way valve on that side.

Using This Manual

The Adjustment and Minor Repair procedures detailed herein may be performed by trained personnel without voiding the unit warranty.

placed. Lightly lubricate all O-rings with clean petroleum jelly prior to assembly. All gasket sealing surfaces must be cleaned prior to installing new gaskets.

Cleanliness is a primary means of assuring satisfactory transmission life. Cleaning parts by using a clean solvent wash and air drying is usually adequate. As with any precision equipment, all parts must be kept free of foreign materials and chemicals. When performing service activities, protect all exposed sealing surfaces and open cavities from damage and foreign material.

All exploded view drawings depict the 28cc frame size. For variances in the 41cc frame size, see the outline drawings in section 3. Differences in wrench size and torquing for the two frame sizes are noted in the text. Note that exterior housing screws are mostly Torx-type T30 or T45. These symbols are used within drawings: Apply petroleum jelly.

Whenever removing a service component, it is recommended that any gaskets and O-rings be re-

Lubricate with clean hydraulic oil.

Safety Precautions

Always consider safety precautions before beginning a service procedure. Protect yourself and others from injury. The following general precautions should be taken into consideration whenever servicing a hydrostatic system.

Loss of Hydrostatic Braking Ability

Fluid Under High Pressure

WARNING When Series 42 units are used in vehicular hydrostatic drive systems, the loss of hydrostatic drive line power in any mode of operation (e.g. acceleration, deceleration or “neutral” mode) may cause a loss of hydrostatic braking capacity. A braking system which is independent of the hydrostatic transmission must, therefore, be provided which is adequate to stop and hold the system should the condition develop.

WARNING Use caution when dealing with hydraulic fluid under pressure. Escaping hydraulic fluid under pressure can have sufficient force to penetrate your skin causing serious injury. This fluid may also be hot enough to burn. Serious infection or reactions can develop if proper medical treatment is not administered immediately.

Flammable Cleaning Solvents

Disable Work Function

WARNING Some cleaning solvents are flammable. To avoid possible fire, do not use cleaning solvents in an area where a source of ignition may be present.

WARNING Certain service procedures may require the vehicle/machine to be disabled (wheels raised off the ground, work function disconnected, etc.) while performing them in order to prevent injury to the technician and bystanders.

4.13 Shaft Seal and Shaft Replacement A lip type shaft seal is used in Series 42 pumps. This seal and/or the shaft can be replaced without major disassembly of the unit. Replacement generally requires removal of the pump from the machine.

Retaining Ring Seal Carrier Assembly

1. Position the pump with the shaft facing up.

NOTE: If the unit is positioned horizontally when the shaft is removed, the cylinder block could move out of place, making shaft installation difficult. 2. Remove the retaining ring from the housing. 3. Pull out seal carrier assembly. 4. Remove the O-ring from the seal carrier. To install a new shaft only, proceed to step 8. 5. Place the seal carrier in an arbor press with the shaft bearing side down, and press out the old seal. An appropriately sized pipe spacer or socket wrench can be used as a press tool. Once removed, the seal is not reusable.

4.16 Filtration Filtration of foreign matter from the hydraulic fluid is of primary importance. Dirt and foreign fluids within the hydraulic circuit will greatly reduce the life of the hydraulic equipment.

M3 Gauge Port Plug

Filtration Plate Retaining Screws

Filter-Related Pump Hardware Filtration mechanisms for the Series 42 pump may be before (suction filtration) or after (charge pressure filtration) the charge pump. Sauer-Sundstrand provides a filtration adapter to provide for each type of filtration configuration. If filtration is provided for elsewhere in the hydraulic circuit, the pump will not have a filtration adapter.

Partial Flow Pressure Filtration

Full Flow Pressure Filtration

Suction Filtration

Pumps equipped with housings without filtration adapters have an additional construction bore next to the charge relief valve which is unused and plugged [5/8 in Hex, 21-33 Nm (15-25 ft•lbf)]. When these pumps are equipped with suction filtration, the external charge inlet is plugged [5/16 in Int. Hex, 41-94 Nm (30-70 ft•lbf)]. Pumps equipped with housings that include filtration adapters have the appropriate adapter and gasket fastened to the housing with screws [Torx T30, 16 Nm (12 ft•lbf)]. The position of the M3 gauge port [11/ 16 in Hex, 11-13 Nm (8-10 ft•lbf)] will vary depending on filtration type.

Housing with Filtration Adapter

Filter Specifications Charge Inlet Plug

The selection of a filter depends on a number of factors including the contaminant ingression rate, the generation of contaminants in the system, the required fluid cleanliness, and the desired maintenance interval. A filter capable of controlling the fluid cleanliness to ISO 4406 Class 18/13 or better is recommended and may be located either on the inlet (suction filtration) or discharge (charge pressure filtration) side of the charge pump.

Construction Bore Plug

E100025 E

Housing without Filtration Adapter (Suction Filtration Only)

Filter capacity depends on desired maintenance levels. As a rough guide, a capacity in grams equal to twice the charge flow in gpm or 1/2 charge flow in l/min has been found to be satisfactory for many closed circuit systems.

Filtration Type Closed Circuit Suction Filtration or Open Circuit Return Line Filtration Systems Sharing a Reservoir with Other Gears, Clutches, or Cylinders Charge Pressure Filtration

Filter efficiency as measured by a "Beta" (β) ratio* should be as in the table at right. See Sauer-Sundstrand publication BLN-9887 or 697581 and ATI-E 9201 for more information on filtration.


Plug

β-ratio β10 ≥ 2 β10 ≥ 10 β10 ≥ 0

* Filter ß x-ratio is a measure of filter efficiency defined by ISO 4572. It is defined as the ratio of the number of particles greater than a given size (x) upstream of the filter to number of particles greater than the same size downstream of the filter. The ßx-ratio applies to a specific particle size, measured in microns.

Use of This Manual

This manual includes information for the normal operation, maintenance, and servicing of the Series 90 family of hydrostatic pumps and motors. The manual includes the description of the units and their individual components, troubleshooting information, adjustment instructions, and minor repair procedures. Unit warranty obligations should not be affected if maintenance, adjustment, and minor repairs are performed according to the procedures described in this manual.

be available, and the unit must be thoroughly cleaned before beginning maintenance, adjustment, or repair activities. Since dirt and contamination are the greatest enemies of any type of hydraulic equipment, cleanliness requirements must be strictly adhered to. This is especially important when changing the system filter and during adjustment and repair activities. A worldwide network of Sauer-Sundstrand Authorized Service Centers is available should repairs be needed. Contact any Sauer-Sundstrand Authorized Service Center for details. A list of all Service Centers can be found in bulletin BLN-2-40527, or in brochure SAW (Ident. No. 698266).

Many service and adjustment activities can be performed without removing the unit from the vehicle or machine. However, adequate access to the unit must

1.2 Safety Precautions

Observe the following safety precautions when using and servicing hydrostatic products.

Loss of Hydrostatic Braking Ability

Fluid Under High Pressure

WARNING When Series 90 units are used in vehicular hydrostatic drive systems, the loss of hydrostatic drive line power in any mode of operation (e.g. acceleration, deceleration or “neutral” mode) may cause a loss of hydrostatic braking capacity. A braking system which is independent of the hydrostatic transmission must, therefore, be provided which is adequate to stop and hold the system should the condition develop.

WARNING Use caution when dealing with hydraulic fluid under pressure. Escaping hydraulic fluid under pressure can have sufficient force to penetrate your skin causing serious injury. This fluid may also be hot enough to burn. Serious infection or reactions can develop if proper medical treatment is not administered immediately.

Flammable Cleaning Solvents

Disable Work Function

WARNING Some cleaning solvents are flammable. To avoid possible fire, do not use cleaning solvents in an area where a source of ignition may be present.

WARNING Certain service procedures may require the vehicle/machine to be disabled (wheels raised off the ground, work function disconnected, etc.) while performing them in order to prevent injury to the technician and bystanders.

2.1

General Description and Cross Sectional Views

2.1.1

Variable Displacement Pumps

The Variable Displacement Pump (PV) is designed to convert an input torque into hydraulic power. The input shaft turns the pump cylinder which contains a ring of pistons. The pistons run against a tilted plate, called the swashplate. This causes the pistons to compress the hydraulic fluid which imparts the input energy into the hydraulic fluid. The high pressure fluid is then ported out to provide power to a remote function. The swashplate angle can be varied by the control piston. Altering the swashplate angle varies the displacement of fluid in a given revolution of the input shaft. A larger angle causes greater displacement which yields greater output torque for a given input. A smaller angle reduces the displacement per revolution and yields greater speed for a given input.

Fixed Displacement Motor

The Fixed Displacement Motor (MF) is designed to convert an input of hydraulic power into an output torque. It operates in the reverse manner of the pump. The high pressure hydraulic fluid enters through the input port. The fluid pressure builds behind the pistons causing them to move down the swashplate (the path of least resistance). As the piston returns up the swashplate again, the fluid is allowed to exit through the exit port. The spinning pistons are housed in a cylinder which is connected to the output shaft. The output torque can be applied to a mechanical function.

Circuit Diagram for Series 90 PV and Series 90 MF

The Basic Closed Circuit The main ports of the pump are connected by hydraulic lines to the main ports of the motor. Fluid flows, in either direction, from the pump to the motor then back to the pump in this closed circuit. Either of the hydraulic lines can be under high pressure. The position of the pump swashplate determines which line is high pressure as well as the direction of fluid flow.

Case Drain Line

Case Drain and Heat Exchanger The pump and motor require case drain lines to remove hot fluid from the system. The motor should be drained from its topmost drain port to ensure the case remains full of fluid. The motor case drain can then be connected to the lower drain port on the pump housing and out the top most port. A heat exchanger, with a bypass valve, is required to cool the case drain fluid before it returns to the reservoir.

Common Features of Pumps and Motors 2.3.1

End Caps and Shafts

Series 90 pumps and motors can be supplied with a variety of end caps and shafts to allow for almost any configuration. For pumps, end caps are available with system ports on either side ("side ports") or both ports on one side ("twin ports"). Motors have end caps with ports on the face of the end cap ("axial ports") or both ports on one side ("twin ports"). See the Series 90 Technical Information manuals (BLN10029 and BLN-10030) or the Series 90 Price Book (BLN-2-40588) for information on available options. Removing the end cap will void the warranty on a Series 90 pump or motor.

2.3.2

Speed Sensors

An optional speed sensor can be installed on Series 90 pumps and motors to provide unit speed information. The sensor reads a magnetic ring wrapped about the unit's cylinder. See Sec. 4 to locate the speed sensor port. See Sec. 8.4 and 9.6 to adjust and install the sensor. 90000810

2.4 Pump Features 2.4.1

Charge Pump

The charge pump is necessary to supply cool fluid to the system, to maintain positive pressure in the main system loop, to provide pressure to operate the control system, and to make up for internal leakage. Charge pressure must be at its specified pressure under all conditions of driving and braking to prevent damage to the transmission. The charge pump is a fixed-displacement, gerotor type pump installed in the variable displacement pump and driven off the main pump shaft. Charge pressure is limited by a relief valve (Sec. 2.4.2). 90000243

The standard charge pump will be satisfactory for most applications. However, if the charge pump sizes available for the given main pump size are not adequate, a gear pump may be mounted to the auxiliary mounting pad (Sec. 2.4.8) and supply the required additional charge flow. For repairs to the charge pump see Sec. 9.2.4.

2.4.2

Charge Relief Valve

The charge relief valve on the pump serves to maintain charge pressure at a designated level. A directacting poppet valve relieves charge pressure whenever it surpasses a certain level. This level is nominally set referencing case pressure at 1775 rpm. This nominal setting assumes the pump is in neutral (zero flow); in forward or reverse charge pressure will be lower. The charge relief valve setting is specified on the model code of the pump (Sec. 8.1.1). For repairs to the pump charge relief valve see Sec. 9.2.3.

2.4.3

Case Drain Line

Charge Relief

System Check Valves

The system check valves allow pressurized flow from the charge pump to enter the low pressure side of the loop whenever system pressure dips below a certain level. This is needed as the pump will generally lose system pressure due to leakage and other factors. Since the pump can operate in either direction, two system check valves are used to direct the charge supply into the low pressure lines. The system check valves are poppet valves located in the multi-function valve assembly (next section).

Multi-Function Valves

All Series 90 pumps include two multi-function valves. The multi-function valve incorporates the system check valve, the pressure limiter valve, the high pressure relief valve, and the bypass valve in a replaceable cartridge. These functions are described separately. There are two multi-function valve cartridges in each Series 90 pump to handle functions in either direction. See Secs. 8.1.2 and 9.2.1 for adjustments and repairs.

NOTE: Some multi-function valves do not include a pressure limiter valve. 90000243

2.4.5

PV showing location of Multi-Function Valves High Pressure Relief / Check Valve Poppet

Pressure Limiter Housing

Series 90 pumps are designed with a sequenced pressure limiting system and high pressure relief valves. When the preset pressure is reached, the pressure limiter system acts to rapidly destroke the pump so as to limit the system pressure. For unusually rapid load application, the high pressure relief valve acts to immediately limit system pressure by cross-porting system flow to the low pressure side of the loop. The pressure limiter valve acts as the pilot for the high pressure relief valve spool. The high pressure relief valve is sequenced to operate at approximately 35 bar (500 psi) above the level that initiates the pressure limiter valve.

Displacement Limiters

Series 90 pumps sizes 042 - 250 are designed for optional mechanical displacement (stroke) limiters. The maximum displacement of the pump can be limited in either direction. The setting can be set as low as 0° in either direction. For instructions on adjustment see Sec. 8.1.5.

Auxiliary Mounting Pads

Auxiliary mounting pads are available on all Series 90 pumps. SAE A through E and H mounts are available (availability varies by pump size). This pad is used for mounting auxiliary hydraulic pumps and for mounting additional Series 90 pumps to make tandem pumps. The pads allow for full through-torque capability. 90000242

PV with Auxiliary Mounting Pad

2.4.9

Filtration Options

All Series 90 pumps are available with provisions for either suction or charge pressure filtration (integral or remote mounted) to filter the fluid entering the charge circuit. (See Sec. 6 for more information.) Suction Filtration The suction filter is placed in the circuit between the reservoir and the inlet to the charge pump. When suction filtration is used, a reducer fitting is placed in the charge pressure gauge port (M3). Filtration devices of this type are provided by the user.

90000243

PV with Suction Filtration (No filtration device attached)

Charge Pressure Filtration The pressure filter may be integrally mounted directly on the pump or a filter may be remotely mounted for ease of servicing. A 200 mesh screen, located in the reservoir or the charge inlet line, is recommended when using this filtration option. A non-bypass filter is preferred on all types of filtration.

89

The pressure override valve (POR) modulates the control pressure to the displacement control to maintain a pump displacement which will produce a system pressure level less than or equal to the POR setting. For unusually rapid load application, the high pressure relief valve function of the multifunction valves is available to also limit the pressure level. The pressure override consists of a three-way normally open valve which operates in series with the pump displacement control. Control supply pressure is normally ported through the pressure override valve to the displacement control valve for controlling the pump's displacement. If the system demands a pressure above the override setting, the POR valve will override the control by reducing the control pressure supplied to the displacement control. As the control pressure reduces, the internal forces tending to rotate the swashplate overcome the force of the servo pistons and allow the pump's displacement to decrease.

Pump Control Options

2.5.1

Manual Displacement Control (MDC)

The manual displacement control converts a mechanical input signal to a hydraulic signal using a springcentered four-way servo valve. This valve ports hydraulic pressure to either side of a dual-acting servo piston. The servo piston rotates the cradle swashplate through an angular rotation of ±17°, thus varying the pump’s displacement from full displacement in one direction to full displacement in the opposite direction. The MDC is designed so the angular position of the pump swashplate is proportional to the rotation of the control input shaft. For adjustments see 8.2.1; for repairs see 9.3.2, 9.3.8.

2

90000237

PV with Manual Displacement Control

Non-Linear MDC The non-linear manual displacement control (photo in Sec. 8.2.2) operates in the same manner as the regular MDC except that it is designed so the change in the angular position of the pump swashplate progressively increases as the control input shaft is rotated toward its maximum displacement position. For adjustments see Sec. 8.2.2; for repairs see 9.3.2. 90000239

Solenoid Override Valve A solenoid override valve option (not shown here) is available for MDC. This safety feature will return the swashplate to zero displacement position when activated. The valve may be set in either a normally open or normally closed mode. For repairs see 9.3.3, 9.3.4.

PV with Manual Displacement Control and Neutral Start Switch

Neutral Start Switch (NSS) The neutral start switch is an optional feature available with MDC. When connected properly with the vehicle’s electrical system, the neutral start switch ensures that the prime mover can be started only when the control is in a neutral position. For adjustments see Sec. 8.2.3.

2.5.2 Hydraulic Displacement Control (HDC) The hydraulic displacement control uses a hydraulic input signal to operate a spring-centered four-way servo valve. This valve ports hydraulic pressure to either side of a dual-acting servo piston. The servo piston rotates the cradle swashplate through an angular rotation of ±17°, thus varying the pump’s displacement from full displacement in one direction to full displacement in the opposite direction. The HDC is designed so the angular position of the pump swashplate is proportional to input pressure. For adjustments see 8.2.4; for repairs see 9.3.5, 9.3.8. Pumps - Motors - Drives

Electric Displacement Control (EDC)

The electric displacement control is similar to the hydraulic displacement control with the input signal pressure controlled by a pressure control pilot (PCP) valve. The PCP valve converts a DC electrical input signal to a hydraulic signal which operates a springcentered four-way servo valve. This valve ports hydraulic pressure to either side of a dual-acting servo piston. The servo piston rotates the cradle swashplate through an angular rotation of ±17°, thus varying the pump’s displacement from full displacement in one direction to full displacement in the opposite direction. The control is designed so the angular position of the swashplate is proportional to the EDC input. For neutral adjustment see Sec. 8.2.4; for repairs see Sec. 9.3.5, 9.3.6, and 9.3.8.

90000241

2.5.4

Automotive Control (AC and AC II)

Automotive Control (AC) allows a vehicle to be driven in a manner similar to an automobile with an automatic transmission. The AC control includes a three-position electric control to provide direction control.

90000353

PV with Automotive Control (AC)

The AC II control can be combined with a manual, hydraulic, or electric displacement control to provide both direction control and control over maximum vehicle speed. It may also be combined with a 3position electric control to provide direction control.

2.5.5

3-Position (FNR) Electric Control

This control utilizes a 12 or 24 VDC electrically operated spool valve to port pressure to either side of the pump displacement control piston. Energizing one of the solenoids will cause the pump to go to its maximum displacement in the corresponding direction.

Start-Up

5

5. Initial Start-Up Procedure

The following start-up procedure should always be followed when starting-up a new Series 90 installation or when restarting an installation in which either the pump or motor had been removed. WARNING The following procedure may require the vehicle/machine to be disabled (wheels raised off the ground, work function disconnected, etc.) while performing the procedure in order to prevent injury to the technician and bystanders. Take necessary safety precautions before moving the vehicle/machine. Prior to installing the pump and/or motor, inspect the units for damage incurred during shipping and handling. Make certain all system components (reservoir, hoses, valves, fittings, heat exchanger, etc.) are clean prior to filling with fluid. Fill the reservoir with recommended hydraulic fluid. This fluid should be passed through a 10 micron (nominal, no bypass) filter prior to entering the reservoir. The use of contaminated fluid will cause damage to the components, which may result in unexpected vehicle/machine movement. See the publications BLN-9887 and SDF 697581 for further related information. The inlet line leading from the reservoir to the pump must be filled prior to start-up. Check inlet line for properly tightened fittings and make sure it is free of restrictions and air leaks. Be certain to fill the pump and/or motor housing with clean hydraulic fluid prior to start up. Fill the housing by pouring filtered oil into the upper case drain port. Install a 50 bar (or 1000 psi) pressure gauge in the charge pressure gauge port (see Sec. 4.2 for location) to monitor the charge pressure during start-up. It is recommended that the external control input signal (linkage for MDC, hydraulic lines for HDC, or


98

electrical connections for EDC) be disconnected at the pump control until after initial start-up. This will ensure that the pump remains in its neutral position. WARNING Do not start prime mover unless pump is in neutral position (0° swashplate angle). Take precautions to prevent machine movement in case pump is actuated during initial start up. “Jog” or slowly rotate prime mover until charge pressure starts to rise. Start the prime mover and run at the lowest possible RPM until charge pressure has been established. Excess air may be bled from the high pressure lines through the high pressure system gauge port. Once charge pressure has been established, increase speed to normal operating RPM. Charge pressure should be as indicated in the pump model code (see Sec. 8.1.1). If charge pressure is inadequate, shut down and determine cause for improper pressure. Refer to Troubleshooting Sec. 7. WARNING Inadequate charge pressure will affect the operator’s ability to control the machine. Shut down the prime mover and connect the external control input signal. Also reconnect the machine function if disconnected earlier. Start the prime mover, checking to be certain the pump remains in neutral. With the prime mover at normal operating speed, slowly check for forward and reverse machine operation. Charge pressure may slightly decrease during forward or reverse operation. Continue to cycle slowly between forward and reverse for at least five minutes. Shut down prime mover, remove gauges, and plug ports. Check reservoir level and add filtered fluid if needed. The transmission is now ready for operation.

8. Inspections and Adjustments This section offers instruction on how to perform inspections and adjustments on pump and motor components. Read through the entire related section before beginning a service activity. Refer to Sec. 4 for location of gauge ports and suggested gauge size.

8.1

Pump Adjustments

8.1.1 Charge Relief Valve Adjustment The following procedure explains how to check and adjust the charge relief valve. (For description see Sec. 2.4.2.) WARNING The following procedure may require the vehicle/machine to be disabled (wheels raised off the ground, work function disconnected, etc.) in order to prevent injury to the technician and bystanders. 1. To measure pump charge pressure, install a pressure gauge in the pump charge pressure gauge port (M3). Also install a gauge to measure case pressure (tee into L1 or L2 or use servo gauge port). Operate the system with the pump in “neutral” (zero displacement) when measuring pump charge pressure. 2. The table on the following page shows the acceptable pump charge pressure range for some nominal charge relief valve settings (see sample model code at right). These pressures assume 1775 pump rpm and a reservoir temperature of 49°C (120°F ), and are referenced to case pressure (see footnote on next page). Smaller displacement charge pumps will produce charge pressure readings in the lower portion of the range, while larger displacement charge pumps will produce readings in the higher portion of the range.

NOTE: These pressures assume a pump speed of 1775 rpm. At higher pump input speeds (with higher charge flows) the charge pressure will rise over the rated setting. 3. Earlier production Series 90 pumps are equipped with a shim adjustable charge relief valve. Shim kits are available from Sauer-Sundstrand. Adjustment of charge pressure is accomplished by removing the plug [1 inch Hex] and changing the shim thickness behind the spring. The plug for this type of charge relief valve should be torqued to 68 Nm (50 lbf•ft). 90000262

Shim Adjustable Charge Pressure Relief Valve (Pump)

Later production Series 90 pumps are equipped with an external screw adjustable charge relief valve. Adjustment of the charge pressure is accomplished by loosening the lock nut (with a 1-1/ 16 inch hex wrench for 030 through 100 units, or a 1-5/8 inch hex wrench for 130 through 250 units), and turning the adjustment plug with a large screwdriver or a 1/2 inch hex wrench. Clockwise rotation of the plug increases the setting, and counterclockwise rotation decreases the setting (at a rate of approximately 3.4 bar (50 psi) per turn). The lock nut for this type of charge relief valve should be torqued to 52 Nm (38 lbf•ft).

8.1.2 Multi-Function Valve Pressure Adjustment Adjustment of the pressure limiter setting and the high pressure relief valve setting is accomplished simultaneously. The latter is automatically set approximately 35 bar (500 psi) above the former. For description of multi-function valve see Sec. 2.4.4. In order to adjust the pressure limiter setting, the motor output shaft must be locked so it does not rotate. This may be accomplished by locking the vehicle’s brakes or rigidly fixing the work function so it cannot rotate. WARNING Take necessary precautions that the motor shaft remains stationary during the adjustment procedure.

90000258

Multi-Function Valves on PV

1. Install two 1000 bar (or 10,000 psi) pressure gauges in the high pressure gauge ports (M1 and M2). Install a 50 bar (or 1000 psi) pressure gauge in the pump charge pressure gauge port (M3). 2. Start the prime mover and operate at normal speed. 3. Loosen locking nut (smallest hex on multi-function valve) with a 10 mm wrench for earlier 042 through 100 frame size units, a 19 mm wrench for 030 and later 042 through 100 frame size units, or a 13 mm wrench for earlier 130 frame size units. 4. Insert a 3 mm (early 042 through 100 units), 5 mm 030 and (late 042 through 100 units), or 4 mm (earlier 130 units) internal hex wrench into the pressure adjusting screw.

NOTE: A plastic dust plug is installed in the adjusting screw on 030 and late 042 through 250 units. 5. The factory preset pressure limiter setting is shown on the model code as at right. It is referenced to charge pressure, so the pressure limiter setting is the difference between the high and low pressure sides of the system loop. Activate or move the control input so that pressure increases in the high pressure side of the closed circuit to the pressure limiter pressure setting. The pressure limiter setting is reached when the pressure stops increasing and remains steady at a given pressure level (as shown on the gauges).

6. Return the pump to its “neutral” (zero flow) position and adjust the pressure limiter setting by rotating the pressure adjusting screw with the internal hex wrench. Clockwise rotation of the pressure adjustment screw will increase the pressure setting, and counterclockwise rotation will decrease the pressure setting. Each complete rotation of the pressure adjusting screw changes the pressure setting by approximately 83 bar (1200 psi) on earlier 042 through 100 units, or by approximately 93 bar (1350 psi) on 030 and later 042 through 100 units. 7. To verify the actual pressure setting, actuate or move the control input so that the pump again develops pressure in the high pressure circuit to the newly adjusted pressure limiter pressure setting, and read the high pressure gauge. Then allow the pump to return to its “neutral” position. The pressure in the high pressure circuit should return to the charge pressure setting.

90000260

Rotate Pressure Adjusting Screw

8. While holding the pressure adjusting screw stationary, tighten the pressure adjusting screw lock nut to 3 Nm (26 in•lbf) on early production units, or 16 Nm (12 ft•lbf) on late production units. Do not over-torque. 9. Shut down the prime mover, remove the gauges and install the gauge port plugs. Replace the plastic dust plugs (if used). The same procedure is used for setting the pressure limit of the other multi-function valve, but the control input signal must be activated or moved in the opposite direction so that high pressure develops in the opposite side of the closed circuit.

8.1.3 Engaging the Bypass Function The bypass function (see Sec. 2.4.6 for description) is performed by the multi-function valve cartridges. The prime mover should be shut down when opening or closing the bypass valves. The bypass valves on both of the multi-function valves must be opened to engaged the bypass function. 1. Using a 1-1/16 inch (030 through 100) or 1-3/8 inch (130 through 250) wrench on the middle sized hex of the multi-function valve cartridge, and a 1-1/4 inch (030 through 100) or 1-5/8 inch (130 through 250) wrench on the large hex to prevent rotation of the cartridge assembly, rotate the middle hex three revolutions counterclockwise to open the bypass valve. Do not rotate more than 3-1/2 revolutions, as additional rotation will permit external leakage. 2. For units with an MDC-type control, prior to moving the vehicle or otherwise causing the motor shaft to turn, move the control handle of the manual displacement control on the pump to the maximum full forward position. Hold the handle in this position during bypass valve operation. WARNING “Tow” at extremely low speeds and for short distances only.

9.1.2 Shaft Seal and Shaft Replacement Lip type shaft seals are used on Series 90 pumps and motors. These seals and/or the shafts can be replaced without major disassembly of the unit. However, replacement usually requires removal of the pump or motor from the machine. 1. Position the pump with the shaft facing up.

NOTE: If the unit is positioned horizontally when the shaft is removed, the cylinder block could move out of place, making shaft installation difficult.

90000270

Remove Screws Holding Retainer Plate and Seal Carrier

2. Remove the three or four screws holding the retainer plate and seal carrier to the housing, using a 10 mm hex wrench (030 and 042 units), a 5 mm internal hex wrench (055 through 100 units), or a 6 mm internal hex wrench (130 through 250 units). Remove the retainer plate.

90000271

Remove Seal Carrier

NOTE: Certain earlier production units use a one piece retainer plate and seal carrier. 3. After removing the screws, the spring force on the shaft may move the seal carrier out of its bore by approximately 5 mm (1/4 inch). If the seal carrier does not move from its bore after removing the screws, pry it from its bore as shown and/or lightly tap the end of the shaft with a soft mallet. 4. Remove the O-ring from the seal carrier. 5. Place seal carrier and seal in an arbor press and press out old seal.

Maintenance Information Fluids Hydraulic fluids used with Sauer-Sundstrand products should be carefully selected with assistance from a reputable supplier following the guidelines presented in the "Hydraulics Fluid Requirements" bulletin BLN-9987.

Incorrect alignment may result in eventual damage to the drive shaft, drive shaft bearings, or the drive shaft seal which can cause external oil leakage. Start Up Procedure Fill the reservoir with recommended hydraulic fluid which should be passed through a 25 micron (nominal) filter prior to entering the reservoir. Never reuse fluid.

The following types of fluids have been used successfully in Sauer-Sundstrand hydrostatic products: 1)Anti wear hydraulic oil. 2)Type F Automatic Transmission Fluid. 3)Engine oils meeting the requirements of API classification CD. 4)Hydraulic transmission fluid of the type used by the agricultural industry for combined transmission, hydraulic and wet brake system. The fluid selected should provide a viscosity between 150 and 275 SSU at 100°F.

The inlet line leading from the pump to the reservoir must be filled prior to start-up. Check inlet line for properly tightened fittings and be certain it is free of restrictions and air leaks. Be certain to fill the main pump housing with clean hydraulic fluid prior to start up. Fill main pump housing by pouring the filtered oil in the upper most case drain hole. Caution! Operation of the pump with less than 160 PSI discharge pressure may reduce the life of the unit.

Caution! As with any hydraulic system, a key to successful operation and predicted life is cleanliness of the various components and the fluid. Strict compliance with component cleanliness recommendations and fluid filtration requirements are a must. Failure to follow such recommendations and requirements can result in excessive pump flow loss and control valve malfunctions that can render an complete system inoperative or even cause catastrophic failure.

See machine operating manual for machine start-up procedures. On mobile applications, run at the lowest possible speed, with a minimum of 160 PSI until system pressure has been established. Once system pressure is positive, increase the speed to full RPM. On electric motor drives jog the motor several times before initial start-up. In both cases if system pressure is not maintained, shut down the system and determine cause.

Installation Prior to installing the pump, inspect for damage during shipment and handling. Make certain all system components (reservoir, hoses, valves, fittings, heat exchanger, etc.) are clean prior to filling with fluid.

The hydraulic system should be operated for at least fifteen (15) minutes under light load conditions. Shut down the system and remove the pressure gauge. Check fluid level in the reservoir and add fluid if necessary.

The pump should be connected to the prime mover so that the centers of both drive shafts are aligned.


The pump is now ready for operation.

Maintenance Information System Maintenance For satisfactory service, regular maintenance of fluid and filters must be performed. Check fluid level daily. Change fluid more often if it becomes contaminated with any foreign matter (dirt, water, grease, etc.) Change Inlet and Return filter whenever fluid is changed and whenever filter indicator shows a change is necessary. Replace all fluid lost during filter change.

Troubleshooting Troubleshooting The information contained in this section provides a guide for troubleshooting Sauer-Sundstrand Series L pumps. It is a problem solving tool aimed at reducing unnecessary machine downtime. Following the fault-logic approach will assist in the expedient correction of system problems.

SYSTEM PRESSURE (TEE 5,000 OR 10,000 PSI GAUGE INTO OUTLET HOSE) INLET VACUUM (TEE VACUUM GAUGE INTO INLET HOSE)

CASE DRAIN (CASE PRESSURE)

Various pressure and vacuum gauge readings can be a great asset in troubleshooting problems with the pump or support system.

INLET

It will be necessary to tee a high pressure gauge into the system pressure line to check the setting of the system relief valve as well as control settings.

RESERVOIR INLET SCREEN

Measuring the inlet pressure will help locate restrictions in the inlet lines, filter, etc. Note: Snubbers are recommended to protect gauges. Gauge calibration is also necessary to insure accuracy of readings.

Minor Repairs Introduction The areas of repair indicated are classified as minor repairs and may be performed, following the procedures in the section, without voiding the unit warranty. Although specific units are illustrated, these procedures apply to all series and types of units in the Series L Family. General Cleanliness is a primary means of insuring satisfactory pump life, on either new or repaired units. Cleaning parts by using a solvent wash and air drying is adequate, providing clean solvent is used. As with any precision equipment, the internal mechanism and related items must be kept free of foreign materials and chemicals.

Removal of a Standard Control

Protect all exposed sealing surfaces and open cavities from damage and foreign material. It is recommended that all gaskets and o-rings be replaced. All gasket sealing surfaces must be cleaned prior to installing a new gasket. Lightly lubricate all o-rings with clean petroleum jelly prior to assembly.

L15, L50, L70 Style Shown

L15, L50, L70 Models

Shaft Seal Removal Two types of shaft seals are used on the L Series pumps. The L15, L50 and L70 models each utilize a seal retainer and O-ring. The L23 and L38 models, however, use a replaceable seal and retaining ring only. Refer to the appropriate instruction which follow for seal replacement. Please note: The seal retainer on the L50 manufactured after serial number 84-50XXXX has been eliminated.

L23 and L38 Models

Using retaining ring pliers, remove the retaining ring from the shaft end of the pump. Caution! The retaining ring holds the shaft in the housing on the L15 model. Do not pull on the shaft after the retaining ring has been removed. In the event the shaft is pulled from the housing, do no attempt to slide it back into the unit. The shaft aligns all cylinder block components, which have

Minor Repairs probably now become misaligned. Reinstalling the shaft by sliding it back in will damage the cylinder block assembly. Once the shaft has been removed, it becomes necessary to remove the end cap and cylinder block. Refer to the major repair section of this manual. L15, L50 and L70 Models Install a screw into each of the two threaded holes in the face of the seal retainer. (The screws which hold the control onto the end cap will fit.) Pull or pry the seal retainer from the housing. The retainer will not come out easily as it is held in place by a large o-ring. Using a seal driver or similar tool, remove the seal from the seal retainer. Discard the seal when removed. Remove and discard the o-ring from the outside of the seal retainer. L23 and L38 Models Using a punch, or some type of sharp instrument, puncture the shaft seal and gently pry it out of the housing. Remove the old seal from the shaft and discard. Installation L15, L50 and L70 Models Use a seal driver or similar tool to press a new seal into the seal retainer. Make certain the seal is bottomed on the counterbore within the retainer. Caution! Do not use excessive force as seal will be damaged. Install a new o-ring on the outside of the seal retainer. Lubricate the o-ring with oil and slide the seal retainer over the shaft and into the housing. Press the seal retainer into the housing until the retaining ring groove is exposed. Install the retaining ring with the beveled side out. Make certain the retaining ring has snapped into the groove completely.

Minor Repairs L23 and L38 Models Lubricate the new seal with oil and carefully slide it over the shaft. Make sure the shaft is covered or other measures have been taken to protect the seal from damage by the shaft keyway. Press the seal into place and securely install the retaining ring in the groove within the housing. Control Using an internal hex wrench, remove the four socket head screws which hold the control on the end cap. Remove the control and gasket from the end cap. Remove the o-ring from the groove in the mating surface of the control.

Minor Repairs It is suggested that a new o-ring be installed on the control and a new gasket placed on the end cap mating surface. Make certain the large hole on the gasket will mate with the o-ring on the control when assembled. Place the control on the end cap and reinstall mounting screws. Tighten to 61-69 in. lbs. torque. Note: The standard controls, which include the pressure compensator, remote pressure compensator and flow and pressure compensator controls, for the L15, L23 and L38 are interchangeable between the three models. Likewise, the standard controls are interchangeable between the L50 and L70 models. All other controls are not interchangeable.

Travel Drive Motor Begin of Stroke Adjustment Procedure All Grayhound Series Pavers Description

Tire and steel track units are set by the motor supplier and adjustment should not be necessary unless a problem is encountered.

The begin of stroke adjustment on the travel motors is required to assure proper automatic shift operation when paver is in “Travel Mode”. It is important that both travel motors shift from “Travel” to “Pave” at the same pressure. Tire and steel track units are set at 2500 psi. Rubber track units are set at 4400 psi.

Rubber track units must be adjusted to match the two sides. This must be done when one or both travel motors are replaced or when a problem is encountered.

Figure 7 Begin of Stroke Adjustment

6) To change the setting turn the adjustment screw in (clockwise) to lower the begin point setting and out (counter clockwise) to increase the begin point setting. Figure 6 Pressure Readings

7) Repeat steps 1 through 6 until the required begin of stroke set point is achieved, stable, and the same on each side.

The G port pressure should rise steadily while the M1 port pressure will rise just a little, remain steady, then start continuing to rise as the dial is turned. Read G port pressure when M1 port pressure starts rising again. This is the Begin of Stroke Point.

8) After obtaining the desired setting, lock begin of stroke adjustment screw into place. 9) Shut down engine.

Caution - Do not allow oil to flow over the high pressure relief valves for long periods of time, as excessive heat can be generated to the pump.

10) Remove individual gauges from G ports and tee one 10,000 psi gauge in G port cross-over line.

4) Note: The begin of stroke setting should be 2500 psi for tire and steel track units and 4400 psi for rubber track units.

Caution - Port G may contain trapped pressure.

5) Break off the tamper resistant cap on the HA control valve adjustment screw and back off the locknut while holding the adjustment screw with a 3mm hex wrench. The locknut requires a 10mm wrench. (Figure 7)

Travel Drive Motor Self-cleaning Swivel-time Orifices All Grayhound Series Pavers

Orifice Plug " B"

Uni-Directional Shuttle Orifice

Orifice Plug " A"

Passage 1

Passage 2

Bi-Directional Shuttle Orifice "M 1" Port Motor Cap

There are two types of self-cleaning swivel-time orifices available, a uni-directional and a bi-directional. This means that one type of shuttle orifice will control flow in one direction and will free flow in the other. The second type of shuttle orifice will control flow in both directions. Both types of shuttle orifices are shown above. A swivel-time orifice kit is made up of two orifice plugs and one shuttle orifice. This kit is inserted into the "M1" port of the motor cap (see page 26 for "M1" port location). There is only one way to properly insert the swivel-time kit. First, thread orifice plug "A" into the "M1" port until it bottoms. Caution: Do not overtighten this orifice plug. Next, insert the shuttle orifice in it's proper orientation for desired flow control. Finally, thread orifice plug "B" into the "M1" port until it is tightly against orifice plug "A". Plug port "M1".


The bi-directional shuttle orifice can be inserted with either tapered end in first. It's orientation does not affect flow control. The orientation of the uni-directional shuttle is important. With the uni-directional shuttle assembled into the motor cap as shown above, controlled flow will be from passage 2 to passage 1 (into the stroking piston). Free flow will occur from passage 1 to passage 2 (out of the stroking piston). To reverse flow control, rotate the uni-directional shuttle orifice 180˚. The orifice plug “B” requires a 5mm Allen Wrench and orifice plug “A” requires a 6mm Allen Wrench. Note: When using a uni-directional shuttle orifice, it will typically be assembled to control motor swivel time from minimum to maximum displacement. Contact Rexroth for more details.

Travel Drive Motor Installation, Start-up, & Troubleshooting All Grayhound Series Pavers Installation The AA6VM motor may be mounted in any position. When mounting in a shaft up position, special considerations regarding the case drain line may be required to ensure the motor bearings are always immersed in oil. The AA6VM is usually face mounted to a final drive gear box with the shaft engaging a mating female splined gear hub or spline adapter. The large drive shaft bearings permit vee or toothed belt pulleys, or gear pinions to be mounted directly to the drive shaft. (Consult Rexroth for radial and axial force limitations.) The motor may also be used to transmit power via a universal drive shaft. The case drain line should be connected to the highest case drain port so that the motor always remains full of oil. For mobile applications, the oil reservoir capacity required (in U.S. gallons) is generally .75 to 1 times the charge pump flow (in U.S. gallons per minute) for a one pump, one motor transmission. The heat exchanger should be located between the pump case drain and the reservoir, and sized to accept the full flow of the charge pump at the maximum anticipated drive speed. To accommodate slight shaft misalignment and to dampen vibration, use of a flexible coupling is recommended. The motor user should work closely with the coupling manufacturer in selecting and applying a suitable coupling . When flexible couplings, Veebelts or toothed timing belts are to be used, the coupling halve, gear or pulley, should be secured to the drive shaft using a spacer between the coupling and the shoulder on the drive shaft, and locking the coupling to the shaft by using a set screw into the threaded hole in the end of the shaft. If this is not possible, as when mounting the motor to a drive gearbox, Optimoly Paste White T multipurpose lubricating paste or equivalent must be applied to the shaft to avoid fretting corrosion of the spline.

Motor Flushing A flushing valve is usually required when a motor will be operated for extended periods of time at high speed and/or high pressure conditions.

Each application should be analyzed to determine the proper method of filtration needed to maintain the required cleanliness levels, as contaminant generation and ingression can vary greatly,depending on the configuration and complexity of the system. For particular system requirement, or for application outside these parameters, a Rexroth Applications Engineer should be consulted. Pre-Start Procedure This should be performed prior to start-up a new installation, or for a system in which new or overhauled components have been fitted. 1. Ensure that hydraulic reservoir piping and pressure hoses are cleaned and flushed. 2. Fill the reservoir through fill pump and filter. 3. If there is any doubt regarding the absolute cleanliness of the system, fit high pressure bi-direction filters in high pressure lines as shown in following diagram. the filters are in addition to the installed suction and return filters.

M

4. Check that all filters have elements of the correct rating and the filter housing are filled with the hydraulic fluid to be used in the system. 5. Where possible, fill the high pressure lines. 6. Open suction line valves.

A flushing valve is available for manifold mounting on the rear cover of an AA6VM motor. This valve provides a regulated flow of oil from the low pressure side of the loop into the motor case. This oil is used to cool and flush the motor bearings. Note: Consult Rexroth application engineer to determine if a motor flushing valve is required for your application.

7. Fill pump and motor case to the highest drain or vent port. 8. Check that all pressure connections are secure. 9. Ensure all mechanical gear boxes have the correct oil type and are filled to the prescribed level.

B

10. Fully back off all high pressure relief valves and then reset one half turn against the spring. 11. Fit 10,000 psi pressure gauges to each high pressure line. 12. Fit 500 psi pressure gauges to charge and pilot circuits. 13. Fit 100 psi pressure gauge to pump case drain port. 14. Fit vacuum gauge to the charge pump suction line, as close as possible to suction port.

EP1 and EP2 Control with Flushing Valve

Filtration The fluid should be filtered prior to system start-up, and continuously during operation to achieve and maintain a cleanliness level of ISO 18/15 (This corresponds approximately to NAS 1638 class 9, or SAE [1963] Class 6.) This recommendation should be considered a minimum, as better cleanliness levels will significantly increase component life.


165

15. Release brakes and jack up the driving wheels. Winches should be started without the cable fitted. 16. Ensure that the fluid temp. in the reservoir is 45F or higher. 17. Ensure that the motor minimum displacement (maximum speed) is set correctly as shown on page 23.

Technical Manual

A Terex Company

Travel Drive Motor Installation, Start-up, & Troubleshooting All Grayhound Series Pavers Start-Up Procedure The following procedure has been developed based on experience with most types of applications, however certain applications may require a departure from or variation to this procedure. For the start-up of new or overhauled installations. 18. Check oil level and temperature.

1. If the prime mover is: Internal combustion engine: (Diesel, gasoline or LP)Remove the coil wire, close the injector rack or leave the gas turned off and turn the engine over until the charge pressure reaches 50 psi or more. Electric Motor: Jog the starting circuit until the charge pressure reaches 50 psi or more. 2. Start the prime mover, and if possible, maintain a pump speed of approximately 750 rpm for 5 minutes. This will allow the system to be filled.

19. Remove and inspect high pressure filter elements, if so equipped. Replace with new elements. 20. Operate transmission under no load conditions for about 15 minutes to stabilize the temperature and remove any residual air from the fluid. 21. Again remove and inspect high pressure filter elements, “if so equipped.” If clean, the high pressure, bi-direction filters may be removed from the circuit. If contamination is still evident, fit new elements and continue flushing until the system is clean.

3. Listen for any abnormal noises. 4. Check for oil leaks.

22. Replace the elements in the charge pump suction or pressure filter, whichever is installed.

5. Run prime mover to 1800 rpm. (Adjust to the design speed if less than 1800 rpm.)

23. Operate the transmission under full and normal load conditions.

6. Set charge and pilot pressure as required for the application. (Refer to circuit schematic)

24. Erratic operation may indicate there is still air trapped in the system. By working the pump control to one or both sides the remaining air can be eliminated. The system is free of air when all functions can be operated smoothly and when the oil in the reservoir is no longer aerated. (Usually less than 1 hour of operation)

7. Bleed the pilot lines by loosening the connections on the motor “X” port(s) and then actuate the remote control unit in both directions until oil seeps from the connections. Also bleed the pilot lines to the pump (if any). 8. Retighten all connections. 9. Operate the control to work the hydrostatic transmission at approximately 20% of maximum speed.

Note: If, after following the Pre-Start and Start-up procedures, the transmission does not perform correctly, refer to the relevant sections of the trouble-shooting procedures on pages 17, 18 & 19.

10. Deaerate system by venting a bleed valve or by cracking the highest connection until fluid seeps out without bubbles. 11. Check fluid level and add fluid if necessary. 12. Continue operating transmission and gradually increase to full speed, still with no load. 13. With controls neutralized, check for creep in neutral. If evident, center the control in accordance with the instructions in the pump service manual. 14. Check that the controls are connected so that the transmission operates in the correct direction related to the control input. 15. Continue to monitor all pressure gauges and correct any irregularities. 16. Apply brakes and set high pressure relief valves (and pressure override if installed) to levels required for the application by stroking the pump to approximately 20% of maximum displacement. 17. Check security of high pressure connections.

Voltage should be at least 2.1 Vdc. If voltage is OK, defective remote slope hand set. If no or low voltage, unplug the harness coming from the burner console to the slope amplifier. Check pins A to B on the socket end. Voltage should be 11 Vdc or more. If voltage, defective amplifier. If no or low voltage, refer to automation. DISPLAY STAYS ON EVEN WHEN UNPLUGGED Replace remote slope hand set unit. SLOPE APPEARS TO BE UNSTABLE OR OSCILLATES Check deadband setting on the slope amplifier. The proper setting is 0.2 light to light. If deadband is OK, unplug remote hand set and check pins B to D. 1500 ohms should be read. If a reading shows 500 ohms, a capacitor is shorted. Replace unit. Check pins A to C for 2500 ohms. Then check for continuity between pins A to B and pins B to C, while rotating the dial. The reading should vary as the dial is turned. If another remote slope hand set unit is available, connect it in place of existing one. If problem disappears, defective remote hand set. Automatic Feed & Grade Control

Gen-III Feeder Controls Introduction The Gen-III feeder control is an optional control system that uses ultrasonic sensors or proportional sensors to monitor and maintain the head of material in front of the screed. As the material level changes the auger/conveyor speed is varied proportional to maintain the set material level.

LH ADAPTER CABLE 09704-416-25 LH PLATE 09704-416-23

Features of the Gen-III Feeder System 1) The screed mounted control unit allows for easy setup and adjustment of the material level without requiring the screedman to relocate the height of the sensor to meet varying conditions. Once the sensor has been mounted and targeted the material level can be adjusted from the rear of the screed.

2) The sonic system has detachable sensor and cable assemblies. The cable has connectors on both ends that allow quick replacement in the event a cable is damaged.

Plug one end the power cable into the RH rear bulkhead of the tractor and the other end into the RH feeder control mounted on the screed (Figure 2). This cable can be left connected all the time. Remove the protective cap from the RH side of the feeder control and plug in the coiled sensor cable (Figure 2). Place sonic sensor in the RH end-gate sonic mount and route coiled cable to it. Plug coiled cable into sensor.

3) Standard proportional feeder controls can be plugged into the Gen-III feeder control and used in place of the sonic sensor. Connecting Sonics Sensors 1) Plug one end of the power cable into the LH rear bulkhead of the tractor and the other end into the LH feeder control mounted on the screed (Figure 1). This cable can be left connected all the time.

Controls Feeder Control 1) AUTO/OFF/MANUAL (Item 1, Figure 6) switch is the primary means to control the auger/conveyor. When placed in the OFF position the auger/conveyor is off; when placed in the MANUAL position the auger/conveyor is turned on. The speed of the auger conveyor when in MANUAL is determined by the pile height knob setting. When placed in the AUTO position the auger/conveyor speed is controlled by the feed sensor. In AUTO mode the auger/ conveyor has the capability of being driven from 0 to full speed depending on sensor output.

When proportional sensors are used with the system the GAIN switch sets the amount of rotation required for the sensing wand to go from OFF to full ON. In LOW gain, the wand will react in a 45° control range (Figure 7). In HIGH gain, the want will react in a 22° control range (Figure 7). Normally, the GAIN switch should be set to HIGH when using the proportional sensor. 1

2) The PILE HEIGHT knob performs different functions depending on sensor used and setting of AUTO/OFF/MANUAL switch. It’s used to set the maximum speed of the auger/conveyor when the AUTO/OFF/MANUAL switch is in the MANUAL mode (Item 2, Figure 6).

Another usage is to set the distance from the face of the sonic sensor to the material when the AUTO/OFF/MANUAL switch is placed in the AUTO mode. Turning the knob counterclockwise lowers the material level. Clockwise rotation of the knob increases the material level.

Finally, it’s used to set the angle at which the proportional sensor shuts off when the AUTO/ OFF/MANUAL switch is placed in the AUTO mode and the proportional sensor is used.

LOW GAIN (45°)

3) GAIN switch must be set in the LOW position when sonic sensors are used with the system (Item 3, Figure 6). When GAIN switch is in LOW, the sonic system controls the speed of the auger/conveyor proportionally within a 5" range. When GAIN switch is in HIGH position the control range is reduced to 2.5". Since the level of the mix can vary by more than 2.5" during normal operation, the sonic control will function like an on/off switch and will not provide proportional control. 20576 (11/00)

Targeting Sonic Sensor Targeting on Active Material The sensor should always be targeted on the material that is actively moving. This area is traditionally on the forward outboard end of the auger (Figure 12). The sensor should be targeted in the center area of the face of material for best results.

The sensor should be mounted in a position that targets the cone shaped field of view of the sensor on the ACTIVE MATERIAL near the outer end of the auger. Sensor Distance The sonic sensor should be no closer than 12 inches and no further than 30 inches away from the face of the material (Figure 10).

Correct

MAXIMUM 30 Inches

MINIMUM 12 Inches

Figure 10

Sonic Sensor Alignment For best possible results the sensor should be targeted perpendicular (90°) to the material surface being monitored. Misalignment decreases the amount of return echo’s to the sensor. The type of material being used determines the amount of misalignment tolerance. Fine graded material designs, like sand mixes, have a low reflective value and require the sensor to be targeted perpendicular while course graded material designs have a high reflective value and may allow up to a 10° misalignment (Figure 11).

Incorrect – Would sense shaft

Figure 12

The most common problem encountered with the use of sonic feeder controls is improper mounting and targeting. The system will react to the object that is inside the view window and closest to the sensor (Figure 12). Care must be taken in mounting and targeting the sensors to prevent sensing objects (end gates, augers, material retaining plates, etc.) other than the desired material level.

Targeting Sonic Sensor Setup & Use of Proportional The following procedure will initially establish the desired material level:

Positioning Proportional Sensor The proportional sensor should be mounted at the outboard end of the auger so the control arm is free to follow the level of material without interference from augers, material retaining plates and end gates. Best results occur when sensing on the active material.

1) Connect the sensor cable to the feed control. 2) Place sensor at the outboard end of the auger. 3) Using the remote handset OVERRIDE/STOP switch or the feed control AUTO/OFF/ MANUAL switch, auger out material until the desired level is established

Correct

4) Place the feed control AUTO/OFF/MANUAL switch in AUTO mode. 5) As the paver start moving adjust the PILE HEIGHT knob until the auger just comes on. 6) Using the GAIN switch can effectively raise or lower the material level. Select the mode that produces the best result.

Figure 13

Setup & Use of Sonic The following steps will initially establish the desired material level.

7) Minor adjustments to the PILE HEIGHT knob can fine tune the level of material that the auger shuts off. Note however the pile height knob has a limited working range (degree of rotation) that the proportional sensor will function in. If The pile height knob is set incorrectly the auger/ conveyor could be either on or off continually.

1) Connect the sensor cable to the sensor and to the feed control. 2) Place sensor in endgate mount and establish preliminary targeting. 3) Using either OVERRIDE/STOP switch or the feed control AUTO/OFF/MANUAL switch, auger out material until the desired level is established

Important: The system will only operate when the traction control lever is in forward and the brakes are released.

4) Place the feed control AUTO/OFF/MANUAL switch in AUTO mode. 5 ) As the paver starts moving adjust the PILE HEIGHT knob until the desired level is maintained. Important: The feed system will only operate in AUTO when the traction control lever is in forward and the brakes are released.

Adjustments for Gen-III Systems Maximum Speed Automatic Mode The following procedure will adjust the maximum speed of the auger in Override mode:

Maximum Speed Manual Override To adjust the maximum speed of the auger in override mode: 1) Engine at full throttle.

1) Engine at full throttle.

2) Press and hold OVERRIDE switch in either the operator console or remote handset to override position.

2) Travel speed dial at 0. 3) Brakes released. 4) Travel lever in forward.

3) Place a tachometer on the end of the auger shaft. The auger should be running between 135 and 150 RPM.

5) Feed control Auto/Off/Manual switch to AUTO. 6) Hold the sonic sensor 4 to 5 feet away from and pointed at the back of the tractor or a truck.

If the auger speed is not within this range, the speed can be adjusted on the conveyor circuit card found in the main electrical junction box on the tractor (Figure 14). The circuit card has three speed adjustments; MAX, MIN and LIMIT. The MIN adjustment is not used with the Gen-III systems. Rotate the MAX adjustment clockwise to increase the auger speed and counterclockwise to decrease the auger speed. If the desired auger speed cannot be reached, rotate the LIMIT adjustment clockwise to increase the upper auger speed limit and continue adjusting the MAX speed adjustment to change the auger speed.

7) Using a tachometer on the end of the auger shaft, adjust the maximum speed set point on the feeder control card located inside the feed control box. The normal setting is 135 to 150 RPM (Figure 15).

Troubleshooting Theory of Operation The Feed Conveyor System consists of a variable displacement hydrostatic pump that drives a hydrostatic motor. Output of the hydrostatic pump can be controlled by a variable electrical signal to the EDC (electrical displacement control) of the pump. A 0 to 2 volt dc signal changes the output speed from zero to maximum. The electrical signal to the EDC is affected by the following four (4) modes of operation:

Quick Troubleshooting Hints: The system consists of two (2) identical subsystems, Left and Right. This allows substitution of working components from one side with suspected nonworking components on the other side. If the problem follows the component, replace the faulty component. If the problem remains on the original side, further testing must be performed.

Manual Override: Signal from the proportional speed module mounted in main electrical junction box triggered by a relay which is energized by the Override switch(es). Fixed output is adjustable via Max and/or Limit pots on conveyor circuit card (Figure 14).

1) Sonic sensor (P/N 46061-100-20) affects automatic operation only.

These components are:

2) Sonic sensor cable (P/N 46061-100-23) affects automatic operation only. 3) Proportional sensor (P/N 46065-500-24) affects automatic operation only.

Manual: Signal from the Feeder Control box at either end of the screed. Speed adjustable via Pile Height knob (maximum speed is non-adjustable).

4) Feeder control box (P/N 46061-100-27) affects manual and automatic operation only. 5) Feeder control board (P/N 46061-100-22) located inside feeder control box affects automatic operation only.

Automatic : Signal from the Feeder Control box at either end of the screed. Speed variable via sensor signal which is limited by the pile height setting. This signal goes through the auto interlock relay contact on the conveyor circuit card in the main junction box on the tractor. This relay activates whenever the brakes are released and the control handle is pushed forward. Maximum output is adjustable via IMAX pot on feeder control board (Figure 15).

6) Proportional speed module (P/N 46065-50027) mounted in tractor main junction box affects override and automatic operation only. 7) Override/Stop toggle switches at console and at screed remotes affect operation in override, manual, and automatic modes.

Stop: Either Override/Stop switch in Stop position disconnects power from the Conveyor pump servo coils.

Sundstrand Automatic Grade & Slope Control Description Automatic screed controls provide a means to enhance a paving operation by monitoring and controlling the screed position in relation to the tractor and the reference plane. This eliminates the need for a screed operator to manually introduce the changes that would be necessary for a uniformly smooth mat to be placed over irregular grades.

All of these reference in a plane parallel to the line of paving. Grade Control The grade controller consists of a housing containing a grade sensing module and an amplifying module which has indicator lights and a mode operation switch. A counter-balanced sensor arm can be attached to either side of the grade sensor. Depending on the application, a wand or a skate assembly is attached to the follower. (Figure 1) A grade sensor can control either the left or right tow point cylinder, depending on which side of the paver it is mounted. Dual grade sensors can also be used to control both left and right sides of the screed.

Automatic screed controls can enhance a good or proper paving operation by maintaining an established line of grade and/or percentage of slope. However, proper operation means controlling all of the factors that can adversely affect the screed. Refer to Quality Paving Guide Book. If these factors are not controlled by recommended operational techniques they can introduce a change in the screed’s position in relation to the established line of grade and/or percentage of slope quickly enough that the automation cannot correct for them. The automation cannot make up for improper operational techniques. Refer to Quality Paving Guide Book.

CABLE

Evaluation of specifications and grade conditions on a job is extremely important if the paver and automation are to be configured properly to produce the desired or required results. Failure to properly configure the screed and automation for each phase of the paving operation will result in producing a mat that is unsatisfactory or will not meet specifications. One configuration of the screed and automation will not produce superior results for all conditions and jobs.

SENSING ARM

SKATE RUNNER

STRINGLINE FOLLOWER

SKATE

The automation system consists of two basic sensory devices, the grade control and the slope control. Both systems operate independently of each other to control the screed’s angle-of-attack by moving the tow points up or down in relation to the reference plane of each. The reference plane for a grade sensory system can be one of three types, ski (mobile grade reference), joint matcher, or fixed (established) string line. The slope system uses an angular reference plane in relation to the horizon, which is perpendicular to the line of paving. Sundstrand Automatic Grade & Slope Control

GRADE CONTROLLER

Figure 1

The sensor arm can be mounted on either side of the sensor, depending on which side of the paver the sensor is to be mounted. The sensor arm has to be mounted so that it is trailing the sensor at 45° angle in relation to the flat on the sensor shaft, to work properly. (Figure 2)

A Terex Company

Sundstrand Automatic Grade & Slope Control If the sensing arm is mounted in a position other than 45°, the amount of rotation on the sensor module, in relation to the amount of deflection of the sensing arm, will not produce the correct amount of tow point cylinder movement. (Figure 3)

Grade Sensor Deadband

Mounting the sensor arm at any angle other than at 45°, changes the amount the sensor shaft is rotated for a given deviation. (Figure 4)

To Set Grade Sensor Deadband:

The deadband of the grade sensor refers to the amount the sensing arm can move without triggering a tow point cylinder response. A given amount is necessary to allow for normal machine vibration. 1) Assemble the grade sensor jack and mounting hardware. Place sensor on the jack and connect the electrical cable from the sensor to the tow point control connector. 2) When installing the sensor control arm, it is extremely important to install so it is trailing the sensor at 45° angle in relation the the flat on the sensor shaft. 3) Place the sensor Run/Standby switch in Standby mode. 4) Place the remote control mat thickness Manual/Setup/Auto switch in Setup mode. 5) Adjust the sensor jack height until both lights are out when the switch on the sensor is in Standby mode and the remote control material thickness switch is in the Setup mode. 6) The deadband is correct when a dime (.050 inch) can be passed under the follower without triggering a light, but a nickel (.080 inch) passed under the follower will trigger a light response. 7) If the deadband is not correct, remove the screw located on the face of the grade sensor. There is an adjustment located under the face screw. 8) Use the small screw driver provided. Clockwise rotation will increase the amount of deadband, while counterclockwise rotation will decrease the amount of deadband.

Sundstrand Automatic Grade & Slope Control Joint Matching Skate 46061-550-06

Notice - Clockwise rotation of the grade sensor jack THICKENS the mat being placed. Counterclockwise rotation of the grade sensor jack THINS the mat being placed.

Matching the height of the mat being placed to an existing mat or curb requires the screed to be very responsive to any changes in the elevation of the existing mat or curb. This is an application where we are building "profile" or over-correcting the screed, forcing it to change depth in a very short distance. This mode is not necessarily good for rideability. 1) The grade sensor should be mounted 3/4 of the way back from the tow point, just ahead of the augers, and the sensor skate in as close to the joint as possible, taking into account the shape of the joint to be matched. If the joint being matched is distorted, it may be necessary to locate the sensor further from the joint. Keep in mind that the further the sensor is from the actual joint being matched, the less likely that an exact match will occur. 2) Place the sensor Run/Standby switch in Standby mode and the remote control mat thickness Manual/Setup/Auto switch in Setup mode.

Sensor Jack

Figure 6

Ski 46061-550-07 When using automation off a ski, corrections to deviations that occur at the sensor or the screed will require the paver to travel approximately 5 lengths of the tow arm before the correction is fully completed. Deviations that occur at the tow point due to the tractor traveling over irregular grades are corrected for immediately. In effect, the sensor is correcting for deviations at the tow point before they can affect the screed's angle of attack (position). In this application, we are building "rideability", or averaging all required changes in depth over a longer area.

The grade sensor should be mounted 1/4 of the way back from the tow point.

Fixed String Line When using automation off an established or fixed string line, it requires the screed to be responsive to any changes in elevation of the string line. This is an application where we are building profile, or overcorrecting the screed and forcing it to change depth in relation to the elevation of the string line. The grade sensor should be mounted 3/4 of the way back from the tow point, or just ahead of the augers. Sundstrand Automatic Grade & Slope Control

Sundstrand Automatic Grade & Slope Control Slope Control

The position of the sensor, whether mounted on the forward cross beam or on the rearward cross beam, determines how fast the screed will react to a change of the null point at the sensor. By positioning the sensor, we can build profile or rideability. We need to evaluate job specifications and grade related conditions to determine the desired mounting position to produce the desired results.

The slope control system consists of a hand-held remote set unit, a slope sensor (pendulum) and an amplifier module which has indicator lights and a mode operation switch. On the CR351 and CR361 pavers the slope sensor and amplifier modules are incorporated into the same mount housing. (Figure 11) All other models have the slope sensor and amplifier modules mounted separately. (Figures 12 & 13) The slope control system can control the left or the right tow point cylinder and is capable of maintaining up to 10% positive or negative slope from each side of the paver. (Figure 14)

8) Turn the remote slope control dial counterclockwise until a light just comes on, then turn clockwise until the light just goes out. Note the number readout on the LCD. 9) Subtract the smaller noted readout number from the larger. Example: 2.1 - 1.7 = 0.4 The deadband is set correctly if the differential from light to light is 0.2% slope. 10) If the deadband is not correct, remove the screw located on the face of the slope amplifier. There is an adjustment located under the face screw. 11)Use the small screw driver provided. Clockwise rotation will increase the amount of deadband, while counterclockwise rotation will decrease the amount of deadband.

When using a slope control system with the sensor mounted on the forward cross beam, corrections to deviations at the screed will require the paver to travel approximately 5 lengths of the tow arm before the correction is fully completed. Deviations that occur at the tow point, due to tractor traveling over irregular grades, are corrected for immediately. In effect, the sensor is correcting for deviations at the tow point before they can affect the screed’s angle of attack (position). In this application we are building “rideability”, or averaging all required changes in depth over a longer area.

To use the slope system: 1) Connect system harnesses to control the desired left or right tow point cylinder as in Setting Deadband section. 2) Pave manually using the depth cranks until the desired slope is achieved on the mat being placed by checking with a carpenters level.

Make sure slope/grade switch is set for unit to be used in. 11) If problem disappears, defective amplifier.

Troubleshooting Sundstrand Automatic Grade & Slope System WARNING - Hydraulic cylinders may activate unexpectedly during testing which could injure someone that is not prepared for such movement. The operator and maintenance personnel must be constantly aware of who is near the paver and what mechanisms may activate during testing. Ensure that personnel are clear of mechanisms that may activate during testing. Amplifier Module

Slope Function Erratic

The same amplifier module is used in both the grade and slope units. The only difference is the setting of the GRADE/SLOPE switch located on the back side of the amplifier module. If the unit is to be used as a grade control, set the Grade/Slope switch to GRADE. If unit is to be used as a slope control, set the Grade/Slope switch to SLOPE.

1) Check all connections for moisture. 2) If tow point cylinder “overshoots” during automatic operation, check for proper cylinder speed. Automation Not Working Properly 1) Perform checks on tractor base wiring and systems to ensure they function properly. 2) Inspect all cables and connections for damage. 3) Check the deadband setting on the amplifier. 4) Check the Grade/Slope switch on the back of the amplifier. It must be in GRADE if the amplifier is used in a grade senor and in SLOPE if the unit is used in the slope system. 5) If slope system is in question, refer to Remote Slope Set. 6) Check tow point solenoid valve DIN connectors for a light. Each solenoid valve has an LED that should light when power is applied to the solenoid. 7) Take the amplifier out of a unit that is known to be functioning properly and install it in the system in question. Make sure the slope/grade switch is set properly for the unit used. If problems disappear,defective amplifier.

Grade or Slope Not Working 1) Perform checks on tractor base wiring and systems to ensure they function properly. 2) Inspect cables and connections for damage. 3) If one side works and the other does not, swap sides with those components and recheck. If problem moves with the component, replace that component. 4) Set Manual/Setup/Auto switch to Manual. Do the tow point cylinders go up and down when selected? If they do, proceed with the next step. If they do not, troubleshoot tractor wiring and/or systems. 5) Set Manual/Setup/Auto switch to Setup, set Standby/Run switch to Run. 6) Disconnect large cable from amplifier. Check pins A to B on cable for voltage. It should be 11 VDC or more. If low or no voltage, troubleshoot tractor wiring and/or systems. Sundstrand Automatic Grade & Slope Control

Unscrew the lens cover from the bulb. Slide a piece of 5/16” inside diameter rubber hose over the bulb. Press down and turn bulb counterclockwise. The bulb can be purchased at most local vendors as #161 (12 VDC) bulb.

Disconnect cable and check ohms between pins.

Remote Slope Set - No Display

No cross continuity.

A to B: 10 ohms C to D: 300 ohms E to F: 300 ohms

1) Check battery in backside of remote slope hand held unit and replace if necessary. A dead battery will cause the LCD to blank out. 2) Check harnesses and connections for damage. 3) Check pins A to C on the slope amplifier (connection point that remote plugs into). Voltage should be at least 2.1 VDC. If voltage is OK, defective remote slope set unit. 4) If no or low voltage, unplug the harness coming from tow point. Check pins A to B on the socket end. Voltage should be 11 VDC or more. 5) If voltage, defective amplifier. 6) If no or low voltage, check tractor base wiring or systems. Remote Slope Set - Display Stays On Even When Unplugged Replace remote slope set unit. Remote Slope Set - Slope Appears to be Unstable or Oscillates 1) Check deadband setting on amplifier. 2) If deadband is OK, unplug remote slope set unit and check pins B to D for 1500 ohms. 3) If a reading shows 500 ohms, a capacitor is shorted. Replace unit. 4) Check pins A to C for 2500 ohms, then check for continuity between pins A to B and pins B to C while rotating dial. Reading should vary as dial is turned. If not, replace unit.

System Four Grade and Slope Automation System Overview

All of the controls for the System Four are on the front panel of the Control Box. The Control Box connects to the Junction Box on the respective side with one cable. It attaches easily with one mounting clamp, and at the end of the day can be quickly removed for storage.

System Four is a complete, non-contacting control system which combines both elevation control and slope control into a simple, easy to use package. The system includes two Control Boxes, two Sonic Tracker II’s and a single Slope Sensor. The Control Box on the right side of the machine controls the right side for either elevation or slope. Likewise, the left Control Box controls the left side for either elevation or slope.

Sonic Tracker II The Sonic Tracker II is an elevation control sensor. It sends out pulses of high frequency sound and measures the time it takes for the echoes reflected from physical objects to return. Sonic Tracker II then sends that information to the Control Box. The Control Box then evaluates the information and raises or lowers the towpoint cylinder to maintain proper mat thickness.

The primary function of the System Four is to provide screed control so that the paving material is placed into position at the correct elevation and slope. Control Box The Control Box is the operator’s interface to System Four. The Control Box receives signals from the sensors, (Sonic Tracker II, Laser Trackers and/or Slope Sensor), and uses these signals to determine if grade or slope correction is necessary. If a change in grade or slope is required, the Control Box sends a signal to the valve controlling the tow point cylinder on the appropriate side of the machine to raise or lower, thus maintaining correct mat thickness.

Sonic Tracker II attaches to the system through one quick connect cable and attaches to the machine with a single bolt. At the end of the day, Sonic Tracker II should be removed for proper storage in the carrying case.

System Four Grade and Slope Automation Slope Sensor The Slope Sensor is a precision electronic sensor which functions much like a precision carpenters level. The Slope Sensor reads the inclination (tilt) of the screed and sends the signal to the Control Box.

The Junction Box allows for quick and easy attachment and removal of the system cables, and once installed on the paving machine it is not removed. Carrying Case A Carrying Case is provided with each System Four. The Carrying Case is lined and includes pre-cut sections for each Sonic Tracker II and Control Box. A plastic bucket is also provided for storing coil cords and cables.

The Slope Sensor is a sealed unit and contains no adjustments. It is the only component of System Four which may be selected to control either side of the paver. It is connected to both Junction Boxes by two cables, and is not removed from the paver once installed.

T

Junction Box The primary function of the Junction Box is to route power and ground from the paving machine to the Control Box, and to route correction signals from the Sonic Tracker II or Slope Sensor to the Control Box. It also routes valve signals from the Control Box to the paving machine valves.

At the end of each job or at the end of the day, always wipe down each of the components and place them and the coil cords in the appropriate sections for storage. This will ensure the continued integrity of these components and will protect them from vandalism or theft. Notice: Keep the Carrying Case dry and store in a dry location. Never let the Carrying Case become wet. If the case does become wet, remove the components and air until dry.

(B) The Slope Sensor measures angle of the slope beam and sends the information to the Control Box.

Sonic Tracker II: How It Works The Sonic Tracker II measures distances to a physical reference (Control Reference) using sound pulses, much like a SONAR.

(C) The Control Box determines if corrections are required and sends correction signals to the pavers hydraulic valve.

A Transducer, located in the bottom of the Sonic Tracker II generates sound pulses like a speaker, and listens for returned echoes like a microphone. When the Transducer generates a sound pulse, it also starts a counter that is a lot like a stopwatch.

(D) The pavers hydraulic valve responds by moving the tow point cylinder to make the correction. Non-Contacting Systems Non-Contacting Grade control or Paving control systems operate from Sonic, Laser or Gravitational sensors that do not require physical contact with a Control Reference to maintain a desired Elevation or Slope. The following sections will explain the

System Four Grade and Slope Automation The Working Window Before paving is started, the operator will use the Control Box to set (or Calibrate) a control region or zone around the Control Reference (see Sonic Tracker II Calibration). This process is called “Nulling”.

The pulse travels away from the Sonic Tracker II at the speed of sound, gradually increasing in diameter.

Sound Pulse

When the sound pulse strikes an object (Control Reference), a portion of the sound pulse is reflected back up toward the Transducer. The size of the cone determines what the Sonic Tracker II can “see”. Objects within the cone reflect sound back (an echo). Objects outside of the cone do not reflect back sound. When the Transducer “hears” the returning sound pulse (echo), the Sonic Tracker II stops the counter. Using the elapsed time measured by the counter and knowing the speed of sound, the Sonic Tracker II calculates the exact distance to the object (Control Reference). It repeats this procedure 40 times per second.

The Working Window is a zone 2.4" above and 2.4" below the On Grade distance. When the distance measured by Sonic Tracker II to the Control Reference is within the Working Window, automatic control of the screed can occur. If the distance measured is outside of the control window, control is switched to manual and no corrections are sent to the control valve unless the measured distance is returned to within the Working Window. This prevents the system from “diving” should the Sonic Tracker II be moved off of a Control Reference like ski, stringline, or curb. Transducer generates a sound pulse and starts timer.

System Four Grade and Slope Automation Under automatic control, the Control Box tries to keep the Control Reference at a constant distance from the Sonic Tracker II (On Grade). If the Sonic Tracker II measures the distance to the Control Reference and the Control Box finds its not at the desired distance (On Grade), the Control Box determines which part of the Working Window (Fine or Course Correction above or below On Grade) the Control Reference is residing in. Once this is determined, the Control Box displays the appropriate correction symbol on its LED Display as well as on the Sonic Tracker II LED Display, and sends correction signals to the paver valve to adjust the screed to bring the screed back to On Grade.

Once the desired Slope has been set at the Control Box, the Slope Sensor measurements will be indicated on the Control Box LCD and LED Displays. When the paver is at the correct slope (On Grade), the Control Box will display the On Grade Symbol.

COARSE CORRECTION UP

Slope Sensor Correction Zones The Control Box receives signals from the Slope Sensor and sets up Correction Zones regions around the On Grade Zone. These Correction Zones are divided into two sections. Just above and just below On Grade to ± .05% is the Fine Correction Zone. Any slope measured beyond the Fine Correction Zones is in the Course Correction Zone. When a slope that is more than ± 2.0% beyond On Grade is encountered, a Grade Adjustment Arrow around the Grade Adjustment Knob will illuminate.

SOLID ARROW DOWN

If the Control Reference is measured to be outside of the Working Window (above, or below 2.4" of On Grade), the LED arrows on Sonic Tracker II will flash once every two seconds, and one of the Grade Correction Arrows around the Grade Correction Knob on the Control Box will flash indicating which way to turn the knob to bring the Working Window back around the Control Reference. The System will also be placed under manual control.

Each of these Correction Zones also have there own symbols. While displaying the desired control slope of the paver on the Control Box LCD Display, symbols will also appear on the Control Box LED’s so the operator knows, at any time, the correction needed for the paver to reach On Grade.

Slope Sensor: How It Works The Slope Sensor has a precision electronic device much like a carpenter’s level inside the slope sensor that constantly measures the slope that the paver is operating on. Using the Control Box to set (Calibrate) the Slope Sensor (see Slope Sensor Calibration), the operator can maintain a desired left hand or right hand slope from +20% to -20%.

System Four Grade and Slope Automation Function

1) Grade Correction Display LED’s

This chapter reviews the System Four components and explains the function of each.

2) Auto/Manual/Survey (Cal) Switch 3) Jog Switch

Notice: When operating in rainy weather or in wet conditions, the Control Box, Sonic Tracker II, and cables must be thoroughly dried BEFORE placing them in the Carrying Case at the end of the day.

4) Elevation: Power Off Slope: Power 5) Grade Adjustment Knob 6) LCD Display All features of the System Four can be accessed using the switches and displays located on the front panel of the Control Box.

Any moisture left on the Control Box, Sonic Tracker II, and/or cables when put in the Carrying Case will cause condensation on the inside of the components which may severely affect accurate operation during the next paving operation.

The function of each is as follows: 1) Grade Correction Display The Grade Correction Display cues you when grade is too high, on grade or too low.

Control Box The Control Box is the main operator control interface for the System Four. It contains LED’s (Light Emitting Diodes) as well as an LCD (Liquid Crystal Display) to inform the operator of the systems performance. The Control Box’s LED’s duplicate the symbols being displayed on the Sonic Tracker II’s LED display.

• Control Box LED’s indicate the correction required to return to grade. Too High (lower tow point to reach grade) Flashes when within .6" 1.5 cm, of On Grade Solid when greater than .6" (1.5cm) but less than 2.4" (6 cm) of On Grade

The Control Box is also the “brains” of the System Four. It receives information from the sensors, processes the information, and sends out correction signals to the paver’s tow arm valves.

If the signal is to short in duration, the operator will hear the paver valve “clicking” but the cylinder will not move. Like wise, if the signal is too long in duration the valve will “spring” wide open causing the cylinder to jump and overcorrect.

Deadband is the area of the Working Window that is On Grade and simply means that while the reference is within that area, the pavers valves are idle (closed). Therefore the wider the Deadband (On Grade area), the more a reference can move up or down without a correction being initiated.

3) 11 Pin Connector - Power and signal communications between the Sonic Tracker II and the Control Box travel via this connector.

NOTICE: Do Not pull the bail forks out far enough to permanently bend them. Repeated bending will weaken the bail resulting in breakage or a bail that will not stay affixed to the Sonic Tracker II.

4) Temperature Sensor - The Temperature Sensor is used to compensate for air temperature changes during non-paving operations. When the Sonic Tracker II Bail is in place, this sensor is overridden by the Bail. Sonic Tracker II Bail The Sonic Tracker II Bail is used to compensate for the rapid air temperature changes that can occur while paving.

2) Making sure the rubber material is all the way to the bail fork ends, place the fork ends in the existing holes in each side of the Sonic Tracker II.

The Sonic Tracker II transducer sends out sound pulses. These pulses bounce off of a physical reference (Ski, Stringline, Curb or Gutter, Existing Mat, etc.) and return to the transducer at the speed of sound. The speed at which these pulses hit the reference and return are affected by the air temperature they travel through, slower through cooler air, and faster through warmer air. The Sonic Tracker II Bail provides a constant physical reference for the Sonic Tracker II to calibrate the speed of sound, thus avoiding effects caused by rapid fluctuations in air temperature over freshly laid asphalt (see Sonic Tracker II How It Works).

3) Once the Bail fork ends are set in the existing holes, gently squeeze the bail forks into the securing slots. Make sure the ends have securely “snapped” into place.

SLOPE SENSOR 46061-551-18

The Transducer operates by generating sound pulses. This is done by sending an electrical charge through a very thin piece of metallic material which vibrates rapidly creating the sound pulse. When oily or moisture laden particles stick to this metallic material it reduces its ability to vibrate therefore reducing the strength of the sound pulse.

Unlike the Sonic Tracker II, the Slope Sensor is a sealed unit and contains no adjustments or user serviceable parts. Once the Slope Sensor is mounted to the paver, all calibration and/ or operating displays are represented on the Control Box. The Slope Sensor contains no displays or adjustments and once the Slope Sensor is mounted to the paver, it is not removed.

NOTICE: During normal operation, the Sonic Tracker II should always have the small piece of Filter Foam over the Transducer assembly. This Filter Foam” will trap most of the contaminants that can foul the Transducer. This Filter Foam’ should be replaced at least every month.

Junction Box The primary function of the Junction Box is to route power and ground from the paving machine to the Control Box, and to route correction signals from the Sonic Tracker II and Slope Sensor to the Control Box. It also routes valve signals from the Control Box to the paving machine.

Over an extended period, very fine particles can pass through the Filter Foam and stick to the Transducer slowly reducing its sound pulse. When this happens 21048 (12/95)

NOTICE: When using grade control, never adjust the screed using the manual hand cranks.

2) If a transverse joint is to be created the quality and durability of the joint depends on careful preparation of the existing mat or lane. It is critical that any taper or defective area be removed. The joint area has to be perfectly flat and parallel with the line of paving! If not, a depression or bump will be produced. Refer to “Transverse Joint” in this chapter

Slope Sensor Calibration To Calibrate the Slope Sensor (Change number readout to reflect percentage of slope being placed): 1) Pave manually using screed depth cranks until desired percentage of slope has been established 2) Follow instructions listed in “Getting an On Grade Bar: (NULLING)” to get the slope control NULLED (on grade bar showing).

4) Nulling the screed is traditionally done with the use of boards that equal the desired loose mat depth. Then a given amount (1¦8” to 1¦4”) of nose up attitude is introduced to the screed. The boards needed should be equal to the thickness of the loose or unrolled mat. The number need will depend the width the screed is set up to pave at. Generally 2 boards at 10' wide, 4 boards at 20' and etc. The length of each board should be such that the screed bottom is fully supported from front to tail when set on the boards.

8) Null the Control Box (s) to get an on grade bar. Refer to “Getting an ON Grade Bar (Nulling)“ in this chapter. 9) Place the Auto/Manual/Survey switch(s) in Auto and begin paving. After the machine has traveled at least a few feet, measure the mat thickness. Make mat thickness changes by making small adjustments using the Grade Adjustment Knob.

5) Null the screed, then manually preset the angle of attack. Refer to “Nulling the Screed” in this chapter 6) Fill auger chamber to exactly 1/2 an auger level. Hand filling outboard ends of the screed to prevent force feeding.

Controlling Yield

Take at least 5 checks about 5 foot apart and average the checks. DO NOT adjust the screed depth after each check. Doing so will produce a rough riding surface. Remember the purpose of a paver is to place a flat mat over an irregular grade.

7) Place the Sonic Tracker II(‘s) 14 inches over the control reference. Refer to “Control References” in this chapter.

NOTICE: When using slope control, never adjust the screed using the manual hand cranks. Adjustments using the hand cranks will require re-calibrating the Slope Sensor. Once satisfactory mat thickness has been reached, you may want to set the Control Box LCD (Elevation) to display that mat thickness.

Place boards or lath that equal the compaction rate of the material from thickness of the joint.

The paver will now maintain the desired mat thickness until another change is desired or the job is completed. Transverse Joints Transverse joints are created when an existing mat or lane is to be continued. The quality and durability of the joint depends on careful preparation of the existing mat or lane. It is critical that any taper or defective area be removed. The joint area has to be perfectly flat and parallel with the line of paving! If not, a depression or bump will be produced.

2) Back the paver up over the joint and align the screed so the face or mold board is square with the edge of the joint. Lower the screed onto the boards or lath and adjust the screed depth cranks so the screed is resting flat on the boards.

Joint Preparation An existing mat should be checked and the tapered area removed to produce a joint area that is flat and parallel with the line of paving.

System Four Grade and Slope Automation 4) The auger chamber should be filled to no more than 1/2 an auger level. Do Not over fill the auger chamber, as this is the most common cause of creating a bump just after pulling off a joint. If needed the corner areas on the ends of the screed should be hand filled to prevent force feeding an excessive high head of material in the center areas of the screed.

We see above a thin mat being placed, but the initial tow point setting is extremely high. In this condition the towing forces are being applied at a upward angle, increasing the lift forces applied to the screed. To maintain a given depth, the angle of attack must be decreased to compensate for the increased lift. The screed is now running with a slight nose down attitude. Only the front portion of the screed is compacting & finishing the material being placed, causing poor mat texture & extreme wear at the front portion of the screed bottom. Also, when the screed stops, it will have more of a tendency to rock or teeter as the tractor relaxes the tension on the screed. This could increase the amount of settling & deviations introduced to the mat. Building Rideability or Profile Evaluation of Jobs

Line of Pull The Line of Pull refers to the angle at which the screed is being towed forward. Best results occur when the towing force is applied relatively parallel to the grade. To do this we set the tow point cylinders in relation to the general depth we will be paving. Line of Pull Applied Parallel to the Line of Paving

Evaluation of specifications and grade conditions on a job is extremely important if the paver and automation are to be configured properly to produce the desired or required results. Failure to properly configure the screed and automation for each phase of the paving operation, or specific conditions, will result in producing a road that is unsatisfactory or will not meet specifications. Just as one size of shoe does not fit everyone, one configuration of the screed and automation will not produce superior results in all conditions and jobs. Building Profile

Rule of Thumb: Thin mats will require a lower initial tow point setting, while thicker mats will require a higher initial tow point setting.

The screed inherently resists immediate changes in depth or slope and averages changes over approximately five lengths of the tow arm. Job specifications that require an exact profile (thickness of material and or slope) at any given point in the grade, require the screed to react very quickly to maintain it’s position in relation to the established line of grade and or percentage of slope. Very simply, when building profile we are over correcting the screed to force it into changing depth very quickly to maintain exact thickness and or slope at

System Four Grade and Slope Automation given points in the grade. Building for profile is not necessarily building a smooth rideable surface, as any changes will be introduced very quickly.

Effective Length of Tow Arm Automation sensors will always move the tow point up or down to maintain the sensors null point, in effect the location of the sensor becomes our control point. The tow point becomes only a point from which we raise or lower the tow arm to reestablish the null point at the sensor. The effective length of tow arm becomes the distance between the control point (sensor) and the pivot point (trailing edge of the screed). Because the screed must travel 5 tow arm lengths to fully react to a correction, shortening the effective tow arm length shortens the distance the paver must travel to complete a correction, therefore increasing reaction time. Moving the sensor towards the screed increases reaction time (builds profile), while moving the sensor towards the tow point decreases reaction time (builds rideability).

Building for profile is desirable on jobs where two or more layers of pavement will be placed or where exacting slopes (transitions & super elevations) have to be built or maintained. By reestablishing or building the desired profile of a road on the first layer, all other layers can be built for rideability or smoothness. Rideability When building for rideability, automation enhances the screeds resistance to immediate changes, producing a very smooth riding surface. Very simply, when building for rideability we are taking a given change and stretching that change over a long area to produce a superior riding surface. Building for rideability is desirable where job specifications place a high emphasis on the smoothness of the finished job. On jobs where two or more layers of pavement will be placed, the first layer should be built for profile to get the grade and slope to proper elevation specifications. All other lifts should be built for rideability, to smooth out any deviations from the previous lift.

Rideability (Foreward)

Effective Tow Arm Length

NOTICE: Never mount Tracker II behind the center line of the augers. This could cause severe over-correction.

Sensor Positioning The position of the sensor on the tow arm determines how fast the screed will react to a change of the null point at the sensor. By positioning the sensor, we can build profile or rideability. We need to evaluate job specifications and grade related conditions to determine the desired mounting position that will produce the required results.

Control References Grade Control (Joint Matching) Joint matching or matching the height of the mat being placed to an existing mat or curb, requires the screed to be very responsive to any changes in the elevation of the existing mat or curb. This is an application where we are building “Profile”, or over-correcting the screed, forcing it change depth in a very short distance.

Rule: Sensor(s) mounted 1/4 the tow arm length back from the tow point builds RIDEABILITY. Sensor(s) mounted inline with the augers builds PROFILE.

The grade sensor should be mounted 3/4 of the way back from the tow point, or just ahead of the augers. 21048 (12/95)

System Four Grade and Slope Automation conditions will not permit running a ski beside the screed. When paving at wide widths the over the screed ski is mounted in close to the tractor, the reference system being close to the tractor, provides the automation a more precise reference in relation to tow point deviations caused by grade conditions, by virtue of being mounted close to the tractor. Problems of flexing mounting hardware simply do not exist due to the close mounting position. The Cedarapids Over the Screed Ski system provides a true independent mounted ski reference system that is not effected by the tractor traveling over irregular grades and provides a very consistent reference plane for the grade sensory system.

With the sensor mounted close to the screed, it is very responsive to any deviation in the screeds position, though not very responsive to deviations of the tow point position, caused by the tractor traveling over irregular grades. Therefore it is not anticipating these deviations , it can only react when a deviation of the tow point position affects the position of the screed. Grade Control (Ski) When using automation off a ski, corrections to deviations that occur at the sensor or the screed, will require the paver to travel approximately 5 lengths of the tow arm before the correction is fully completed. Deviations that occur at the tow point, due to the tractor traveling over irregular grades, are corrected for immediately. In effect the sensor is correcting for deviations at the tow point before they can affect the screeds angle of attack (position). In this application we are building “Rideability”, or averaging all required changes in depth over a longer area.

Mount the Sonic Tracker II 14 inches above the top wire. A piece of 1/8” tubing should be placed over the wire to increase its reflective surface for best results.

The grade sensor should be mounted 1/4 of the way back from the tow point. With the sensor mounted in the forward position, any deviation at the tow point caused by the tractor traveling over irregular grades, will cause the sensor to react immediately, to correct for that deviation. Therefor maintaining the same tow point position (angle of attack on the screed) in relation to the reference (ski), regardless of the grade irregularities.

Surface Stringline

The Sonic Tracker II can follow nearly any existing surface. Simply place the Sonic Tracker II 14 to 24 inches above the surface. Get an On Grade Bar (Refer to “Getting an On Grade Bar Sonic Tracker II Control “ earlier in this chapter), switch the Control Box to Auto and start paving.

A Surface Stringline is stretched over a given length of grade. It rests on the high places and bridges the low, creating an average over a distance as long as 1500 feet. Since the Sonic Tracker II is noncontacting, it can track Surface Stringline without deflecting it, producing an average of the surface. Surface Stringlines can produce acceptable results in low specification type jobs, but traditionally are not used in very demanding or high specification jobs.

Notice: Using automation to follow existing surfaces is NOT RECOMMENDED as every deviation in the existing surface will be introduced into the mat being placed.

Once Surface Stringline is in place, all you need to do is line up the Sonic Tracker II 14 to 18 inches above the string, get an On Grade Bar and switch to Auto.

Curb or Gutter A curb or gutter that is poured before paving can be used as a reference. Simply line the Sonic Tracker II 14" above the curb or gutter edge and get an On Grade Bar. Switch the Control Box to Auto and start paving. Notice: Curbs and gutters make a very poor reference if smoothness of the placed mat is of concern. This is due to the variations in elevation along the length of the curb or gutter.

The diagram may also be used to determine the specific part number of a cable needed to connect to a specific paver. Simply find the cable on the diagram, then use the Cable Specification Chart to determine the part number for the cable to your paver.

6) Place the black Retaining Ring over the Transducer assembly with the beveled edges out and the flat surface against the Sonic Tracker II base. Lineup the holes for the mounting screws (the mounting screw holes are set to an irregular pattern. This ensures the retaining ring will only line up with the mounting holes one way). 7) Start the mounting screws into the holes and tighten each until firm. DO NOT OVER TIGHTEN. Use a cross (X) pattern to tighten screws. NOTICE: Over tightening may distort the Transducer metallic material and may crack the Retaining Ring. Use of the O-Ring assures tightness while preventing vibration from loosening the Mounting Screws. NOTICE: DO NOT use Loctite on the mounting screws. Loctite will attack the plastic retaining ring.

8) Make sure no wrinkles in the metallic surface is visible inside the Transducer. If distortion is evident repeat Steps 5 through 8. 21048 (12/95)

Chapter 1: System Overview

System Overview System FiveTM is a complete, non-contacting control system which combines both elevation control and slope control into a simple, easy to use package. A standard system includes two (2) Control Boxes, two (2) Sonic Tracker IITM's and a single (1) Slope Sensor. The Control Box on the right side of the machine controls the right side for either elevation or slope. Likewise, the left Control Box controls the left side for either elevation or slope. The primary function of System FiveTM is to provide screed control so that the paving material is placed into position at the correct elevation and slope.

1-1 Figure 1.01 System FiveTM Paver Operator's Manual


1-2



Control Box The Control Box is the operator’s interface to System FiveTM. The Control Box receives signals from the sensors, (Sonic Tracker IITM, Laser Tracker and/or Slope Sensor), and uses these signals to determine if grade or slope corrections are necessary. If a change in grade or slope is required, the Control Box sends a signal to the valve controlling the tow point cylinder on the appropriate side of the machine to raise or lower, thus maintaining correct mat thickness. The Control Box easily attaches to its mounting bracket with one clamp, and at the end of the day should be removed for storage. The Control Box connects to the Sonic Tracker IITM, the Slope Sensor, and to the paver through electrical cables.

1-3 Figure 1.03



Sonic Tracker IITM The Sonic Tracker IITM measures and controls the elevations of the screed. A transducer, located in the bottom of the Sonic Tracker IITM, generates sound pulses like a speaker and listens for returned echoes like a microphone. The Tracker measures the distance, and controls grade from a physical grade reference, such as a curb, stringline, or existing road surface. A bail is used to compensate for rapid air temperature changes. In paving applications a bail should always be used. The Sonic Tracker IITM attaches to the system through one quick connect cable and attaches to the machine with a single bolt. At the end of the day, Sonic Tracker IITM should be removed for proper storage in the carrying case.



Slope Sensor The Slope Sensor is a precision electronic sensor which functions much like a precision carpenter's level. The Slope Sensor reads the inclination (tilt) of the screed and sends the signal to the Control Box. The Slope Sensor will measure slopes from +20% to -20%. The Slope Sensor is a sealed unit and contains no adjustments. It is the only component of System FiveTM which may be selected to control either side of the paver. It is connected to each Control Box through an electrical cable. The Slope Sensor is a sealed component and once attached to the paver should not be removed.

Figure 1.05


1-5


Smoothtrac® Sonic Averaging System (SAS) The Smoothtrac is an elevation control system that combines multiple Sonic Tracker II's together to calculate an average of the physical reference. Each tracker sends its distance measurement to the Control Box which then averages all of those measurements and sends a correction signal to the tow point cylinder. The Smoothtrac replaces the mechanical ski that drags on the ground. The Smoothtrac connects to the Control Box through the tracker cable.

1-6

Figure 1.06



Laser Tracker & Trackerjack The Laser Tracker is an elevation control sensor. It measures and controls the elevation of the screed. It works by receiving a signal from a rotating laser and sending a signal to the Control Box. The Trackerjack attaches to the laser receiver and then mounts onto a vibration pole. Use the same cable from the Sonic Tracker IITM to power up the Laser Tracker/Trackerjack System. The Laser Trackerjack should be removed at the end of each day and stored in its carrying case. Figure 1.07

1-7



Carrying Case A Carrying Case is provided with each System FiveTM. The Carrying Case is lined and includes pre-cut sections for each Sonic Tracker IITM and the Control Boxes. A cut-out section is also provided for storing coil cords. At the end of the day, always wipe down each of the components and place them and the coil cords in the appropriate sections for storage. This will ensure the continued integrity of these components and will protect them from vandalism or theft.

Figure 1.08

NOTICE 1-8

Keep the Carrying Case dry and store in a dry location. Never let the interior of the Carrying Case become wet. If the case does become wet, remove the components and dry it out. System FiveTM Paver Operator's Manual

Chapter 2: Operation

Operation NOTICE When operating in rainy weather or in wet conditions, the Control Box, Sonic Tracker IITM, and cables must be thoroughly dried BEFORE placing them in the Carrying Case at the end of the day. Any moisture in the Carrying Case will cause condensation on the inside of the components which may severely affect accurate operation during the next paving operation.

Control Box The Control Box is the main operator control interface for System FiveTM. The Control Box receives signals from the sensors and uses these signals to determine if a grade or slope correction is necessary. If a correction is necessary the Control Box sends a signal to the valve controlling the tow point cylinder on the appropriate side of the paver to raise or lower, thus maintaining correct mat thickness.

2-1



Control Box Front Panel Switches, Buttons and Controls The operator can control and monitor the slope and thickness of the mat using the buttons and displays located on the front panel of the Control Box. The function of each is as follows:

3 Audible Beeper When the power is turned on, or calibration selections are made, the beeper will sound. The beeper may be turned Off or On for certain functions by using the Beeper Alarm Mode (see Accessing System FiveTM Performance Settings section in this booklet). System FiveTM Paver Operator's Manual


Sonic Tracker II The Sonic Tracker IITM measures and controls the elevation of the screed. A transducer, located in the bottom of the Tracker, generates sound pulses like a speaker and listens for returned echoes like a microphone. The Tracker measures the distance, and controls grade from any physical grade reference, such as a curb, stringline, or existing road surface.

Figure 2.11a

2-13



The Sonic Tracker IITM measures the distance to a physical reference by sending out sound pulses 39 times per second. As soon as the Tracker sends out a sound wave it starts a stop watch. The sound waves go down, bounce off of any physical reference, and are reflected back to the Tracker. The Tracker measures the time it takes for the sound wave to return to the Tracker. Knowing the speed of sound, the Tracker accurately calculates the exact distance to the grade reference. The Tracker can use any physical grade reference, such as a stringline, curb, or existing surface.

2-14

Figure 2.11b



•

Working Window Since the Sonic Tracker IITM is mounted to the tow arm or screed extension, as they raise or lower, the tracker measures exactly how far above or below the desired grade reference it is. Built into the Tracker is an operational zone, or Working Window, 2.4 inches above and below the grade reference. The grade lights on the Sonic Tracker and Control Box continuously display this grade information to the screed operator.

2-15 Figure 2.12a



On the paver the Sonic Tracker II will be positioned above the grade reference. Its job is to maintain the exact distance from the tracker to the reference, keeping the Tracker On Grade. If the Tracker is On Grade, the mat being laid will be at the desired depth.

Figure 2.12b

2-16



If the screed and the Tracker IITM start to raise, the watch will be stopped at a longer time. The Tracker and Control Box will indicate a down correction arrow, and lower hydraulic valve corrections will be applied to bring the Tracker back to On Grade.

Figure 2.12c

2-17



If the screed and Tracker IITM are lowered the watch will be stopped at a shorter time. The Tracker and Control Box will indicate a raise correction arrow, and raise hydraulic valve corrections will be applied to bring the Tracker back to On Grade.

Figure 2.12d

2-18



If the Tracker IITM is side shifted off a stringline, the sound waves reflect off the ground and the Tracker's stopwatch will indicate a long time for the sound waves to return. The Tracker is out of the Working Window, and no On Grade correction signals will be applied.

Figure 2.12e

2-19



If the Tracker sees an obstruction closer than the reference signal, such as a grade pin, the sound waves do not take as long to come back and the stop watch is stopped much sooner. The Tracker is out of the Working Window, and no On Grade correction signals will be applied.

Figure 2.12f

2-20



Temperature will change the speed of sound. The tracker has a built in temperature sensor for applications with gradual temperature changes such as on graders or dozers. In paving applications you can get a more dramatic and rapid change in air temperature. To compensate for these variations a temperature bail is positioned 9 inches below the tracker. When the sound wave is emitted, the tracker records the time to the bail and continues to listen for the grade reference. If a temperature variation occurs, such as heat off a freshly paved mat, a difference in time to the temperature bail is recorded. The correction for the speed of sound is then applied to the grade reference signal, preventing a change in mat depth. The tracker corrects for temperature variations with every sound wave, 39 times per second.

2-21 Figure 2.12g System FiveTM Paver Operator's Manual


In the upper right hand corner of the Sonic Tracker IITM faceplate is a small symbol used to represent the use of the temperature bail. The LED symbol will automatically illuminate when the bail is connected to the tracker. The tracker is casted with holes on each side for the bail to snap and lock into place.

2-22 Figure 2.12h System FiveTM Paver Operator's Manual


When setting up the Tracker over a grade reference, the size of the Sonic Cone or the "footprint" needs to be considered. As an example, at about 2 feet from the tracker, you will have a footprint or cone of about 6 inches. As the Tracker is positioned closer to the grade reference the working footprint decreases in size. As the Tracker is moving farther away from the grade reference the sonic footprint or cone will increase in size.

Figure 2.12i

2-23



For Laser Control a laser transmitter is used to produce a plane of light which becomes the grade control reference for the job site. The laser receiver will control the screed to lay a mat parallel to the laser beam reference. When the laser beam is in the center of the receiver, it indicates an On-Grade signal.

Figure 2.12j

2-24



As the screed is raised, the beam of light hits the Laser Receiver below the center and a lower signal is indicated.

Figure 2.12k

2-25



As screed is lowered the beam of light hits the Laser Receiver above the center a raise signal is indicated.

Figure 2.12l

2-26



•

Slope Control System Five uses a slope sensor mounted to the transducer beam on the paver to measure and control the slope of the mat being laid. The sensor contains an electronic level vial, that acts as a "precision carpenter's level". Slope control with this electric level vial is very accurate and repeatable.

Figure 2.12m

2-27



If the required slope changes, the screed man dials the new slope in the System Five Box. The tow point cylinder on the slope side will raise or lower until the slope sensor measures the new slope.

Figure 2.12n

Chapter 3: Performance Menu

Performance Menu Control Box Memory The Control Box automatically stores all operating information when it is turned off. NOTICE If power is interrupted to the Control Box within 2 seconds after making an adjustment, the new setting will not have had time to be stored and the settings will revert to the previous (or original) settings. Accessing System Five TM Performance Menu Settings System FiveTM Performance Menu Settings are a series of features that allow System FiveTM to be modified for operator ease-of-use reasons, or performance enhancement reasons. Performance Menu Settings Chart



NOTICE Some of the Menu selections may not be available for the operator to select or change. Please contact dealer/distributor with any questions. NOTICE The factory settings are preset values that will run most pavers.

Gain (Elevation) This setting determines the speed at which System FiveTM allows the Tow Point Cylinders to adjust to a change in elevation. For faster hydraulic response, increase the gain value. For slower hydraulic response, decrease the gain value. The objective is to set the gain so the screed reacts to the change in grade quickly but without "overshooting" the new elevation. • •

Gain Elevation Value Range: 1-100 Factory Preset: 25 NOTICE

Before setting the Gain, make sure the machine's hydraulic flow controls valves are adjusted for proper cylinder speed according to the manufacturer's recommendations. Typical cylinder speed is 15-20 seconds for full up or down cylinder travel. 1. Press the Auto button to select Gain (Elevation).

NOTICE Do not set slope gain at a higher value than the elevation gain on the other side of the paver. A higher value may cause the slope to be over reactive.

3-8



Valve Offset The valve offset is the minimum amount of electrical signals sent to the valve which causes the hydraulic cylinder to move. If the valve offset is too small, the sensor will not reach On-Grade. Likewise, if the valve offset value is too large, the sensor will move too much and overshoot On-Grade. Valve offsets should be set before adjusting elevation and slope gains and averaging. •

•

Valve Offset Value Range: 1-700 Solenoid: 135 Proportional: 350 Factory Preset: 135 NOTICE

Valve offsets should be the first performance menu function completed. The paver should be run until the hydraulic oil is at normal operating temperature before the value offset functions preformed. Once they are set, valve offsets should not need to be adjusted unless the Control Box has been moved to a new paver, or the hydraulic performance has changed. 1. Press the Auto button to select Valve Offset. This will automatically activate the value screen for Raise Offsets. The Raise Grade Correction Display Arrow will illuminate, and the Control Box will begin sending a raise correction signal to the valve.

Averaging This setting changes the amount of dampening, or filtering, applied to sonic tracker and laser receiver measurements. It can be thought of as the time period over which a running average of the elevation measurement is calculated. A lower value will average fewer elevation measurements, allowing the system to react more quickly to smaller grade changes. This will make it more susceptible to fluctuations in temperature or small obstructions. A larger value will average more elevation measurements, preventing the system from reacting to undesirable items close to the reference. This will also make it less susceptible to fluctuations in temperature or small obstructions. • •

Averaging Value Range: 1-100 Factory Preset: 50 1. Press the Auto button to select Averaging.

Deadband Elevation Deadband is the area of the Working Window that is OnGrade. While the reference is within that area, the paver’s valves are idle (closed). Therefore the wider the Deadband (On-Grade area), the more a reference can move up or down without a correction being initiated. Once the signal from the reference is out of the deadband, System FiveTM will drive the hydraulics to place the reference back in the CENTER of the deadband. • •

Deadband Elevation Value Range : 1-30 mm Factory Preset : 3mm (.01', or 1/8") 1. Press Auto Button to select Elevation Deadband.

Figure 3.06a

2. Turn the Grade Adjustment Knob to select the desired value - typically 3mm (0.01').

Figure 3.06b

3. Press the Auto button again to store the value. 4. Rotate the Grade Adjustment Knob to access another choice in the Performance Menu or press the Set/Menu button to exit. NOTICE The amount of Deadband should be carefully selected. Too small of a Deadband will cause the tow point cylinder to constantly hunt up and down while the sensor tries to find On-Grade. Too large of a deadband will not allow the sensor to send grade corrections to the valves, causing unwanted variations in the mat thickness.

Deadband Slope Deadband is the area of the Working Window that is OnGrade. While the reference is within that area, the paver’s valves are idle (closed). Therefore the wider the Deadband (On-Grade area), the more a reference can move up or down without a correction being initiated. Once the signal from the reference is out of the deadband, System FiveTM will drive the hydraulics to place the reference back in the CENTER of the deadband. When the Deadband is changed it adds or takes away from the fine correction region (1% above or below On-Grade) of the slope sensor. It does not add this distance to the overall working range. • •

Chapter 4: Principles of Paving

Principles of Paving

Figure 4.0

Paver Components Modern pavers consist of two major units: The Tractor and the Screed. The primary function of the tractor is to propel the truck or paver feeding device, to convey and distribute the paving material and to tow the screed. The function of the screed is to strike off the material in preparation for further compaction. The screed is mounted to the tow arms at the screed pivot points and is attached to the paver at the tow points.


4-1


How a Screed Works

Figure 4.01a

The screed on all modern pavers is of the "floating, self leveling" type. As the paver tows the screed unit forward, paving material flows under the screed. This causes the screed to float on the mat of material, thus establishing mat thickness. Since the screed is mounted to the paver only at the tow points, the screed is completely free to float up or down. The screed will always seek it's own "Planing Angle", or angle of attack, dependent on the combination of forces acting upon the screed.

4-2

Figure 4.01b



• •

If the screed angle of attack is increased the screed rises increasing the mat thickness. If the angle of attack is decreased, the screed will settle providing a thinner mat surface.

Figure 4.01c

Because the screed floats, it will not immediately react to a change in the tow point. It needs a certain amount of time or distance to make a correction in the mat thickness. If the tow point is changed by a unit of one, the paver must move one tow arm length before the screed will correct 63% of the elevation. After 2 tow arm lengths 83% of the correction is made and 3 tow arm lengths would account for 95%. It takes 6 tow arm lengths to achieve 100% of the elevation change. Considering that 95% of the change takes place after 3 tow arm lengths, this can be used in practical applications to qualify for full correction.

4-3 Figure 4.01d System FiveTM Paver Operator's Manual


The same is true when making elevation changes with the manual thickness cranks.

Figure 4.01e

It is very important to check mat depth in several locations before making any elevation corrections. The surface being paved may have wheel ruts, dips and ridges that will give an untrue indication of overall mat depth. Check several spots to get an average. If an elevation change is made, wait 3 tow arm lengths for full correction. Too much cranking and stabbing will cause raise and lower changes that will produce an uneven mat surface.

4-4 Figure 4.01f System FiveTM Paver Operator's Manual


There are four main forces acting on the screed at all times. These forces occur whether you are paving in manual or with automatics. A change in any one of the forces will cause the screed to rise or fall, changing the mat depth. The key to smoother paving is to keep these forces as constant as possible. Let's review each of the forces and what factors will have an effect.

Figure 4.01g

4-5



Tow Point Force The tow point force (P) is the resistance to forward travel. The P force will remain constant if the paver is kept moving at a consistent speed at all times. If the paver is allowed to stop, the screed will settle in the fresh mat and leave a mark. The mark cannot be fully smoothed out by the roller and a bump will end up in the mat. This will show up in the profilograph readings and reduce your chance for any bonuses. Changing the speed of the paver will also cause the screed to rise and fall, affecting the mat thickness. The optimum paving speed is determined by the depth and width being paved and the rate at which material can be delivered to the job. Calculate the tons/ hour into feet per minute. Do not start and stop the paver.

Figure 4.02

4-6



Truck Exchange is another tow point force. It is very important that truck exchanges be carried out as smoothly as possible to avoid disturbing the smooth, uninterrupted forward motion of the paver. The following lists some steps to take to avoid disturbance of the paving operation by trucks. 1. Stop the mix delivery truck close, but not too short of the paver. Always allow the paver to pickup trucks on the run. 2. Never allow the truck to bump the paver. Allowing trucks to bump the paver when backing up, can drive the screed into the mat and produces bumps and ridges which may not roll out. 3. Trucks applying and holding their brakes excessively while dumping their load may cause the paver to slow, which in turn will cause the screed to rise. The truck driver should apply only light pressure on the brakes, sufficient to maintain contact with the paver. 4. Dumping of material in front of the paver as the truck pulls away after emptying its load into the hopper, can cause the paver to ride over the pile of material with subsequent adverse effects on mat quality. Avoid trucks pulling away prior to completely dumping all material. Use a dump person to monitor and regulate truck movements in front of the paver.

4-7



"M" Head of Material As described before, one of the primary functions of the paver tractor is to convey and distribute paving material onto the ground in front of the entire width of the screed. This material, once deposited in front of the screed is the head of material over which the screed will pass. One of the keys to smooth paving is to maintain this head of material as constant as is possible. The resistance to forward motion exerted by the head of material (M) is one of the major component of resistance to forward motion. Control of this force is a basic and necessary function of any paving operation. The volume and consistency of the head of material determines how much paving material flows under the screed and influences mat thickness and surface texture.

Figure 4.03a

4-8



The most common factor affecting force "M", the head of material, is the following: Incorrectly Adjusted Automatic Feeder Controls: These systems, whether they are of the "hanging paddle" type or the sonic sensors should be adjusted to operate the auger/conveyor assemblies 95 to 100% of the time. On/off operation of the auger system will cause fluctuation in the head of material. The highest quality mat will generally result when a constant head of material is maintained across the entire width of the screed and the material almost covers the auger shaft. If the volume of paving material is too high, there is resistance to the travel of the screed. This causes the screed to rise and can result in ripples, auger shadows and long waves. It also results in increased auger wear.



"R" Reaction of Material Under Screed Ideally, every truck load of material delivered to the paver would be exactly like every other load with no variation. However, as a practical matter, changes in mix characteristics such as mix temperature, density, gradation, A.C. Content, segregation, etc., will affect the internal stresses developed within the mix, which in turn affects the resistance of the mix to flow under the screed. The key element to bear in mind is that the screed passing over the paving material will compact the material to a certain degree. Variable in the resistance of the material to compactive forces will cause changes in the screed's angle of attack, which in turn will affect mat thickness and therefore mat smoothness.

Figure 4.04

4-10



Mix Characteristics Gradation This aspect of the paving material will vary according to the intended use of the material as abase course, binder course or the final wearing surface. Normally, maximum aggregate size, ratio of aggregates, fines content and most importantly, asphaltic binder content, is specified by the contracting agency. Adherence to mix design specifications is usually the responsibility of the material supplier. Segregation is a material deficiency caused by a separation of the larger aggregate sizes from the bulk of the paving material. This condition is encountered especially in mixes with relatively large maximum size aggregate (example: 1" and larger, the so called "large-particle" mixes). When paving material is deposited in piles, as in an asphalt plant silo, a haul truck, a paver hopper, on the ground in front of the paver in a windrow, or on the ground in the auger chamber, segregation can and does frequently occur. NOTICE The areas listed above where segregation can occur are all areas that the material may encounter before being laid down as a mat. Therefore, these areas of segregation must be addressed prior to any paving. The screed cannot rectify segregation during the paving process.

4-11



Segregation can also be the result of improper hopper dumping: Duration normal operation, the vibration of the pavers hopper will cause segregation. Therefore, dumping the hopper after each truck should be avoided because material that has rolled to the outside of the hopper (the large aggregate) will fill the conveyors and auger chamber and result in a segregated area behind the paver with a noticeable difference in surface texture. If It Doesn't Look Right, It Isn't Right: Surface and texture irregularities indicate that the homogeneous characteristics of the material in the mat have been interrupted, which usually results in bumpiness and premature failure of the pavement in those areas. Segregation can also be the result of excessively worn augers: "Center Streak" segregation can be caused by worn "Kicker Paddles" at the center chain cause or near the outside auger bearings. In fact center streak segregation is frequently caused by incorrect arrangement of the auger segments adjacent to the auger chain case. (Consult the Manufacturers Manual). "Center Streak" segregation is also caused by feeder gates being set to tow. Adjust as necessary to provide sufficient uniform material at the center of the paver. NOTICE "Center Streak" segregation can be limited and even eliminated by slowing paving speed. 4-12



Mix Temperature A common paving problem is inconsistent temperatures in the asphalt mix. As the material cools it loses its viscosity making it more difficult to compact. If the resistance to compaction increases, the screed will naturally increase its angle of attack and begin to float up. This will change the mat depth, resulting in bumps in the surface. If the mix and or screed temperature are too low, the screed may no longer slide smoothly over the material and a tearing of the mat will occur. Some simple steps to take to control temperature variations: A. Ensure that haul trucks take the shortest, most practical route to the paver. Make certain that all trucks take the same route to the paver. B. Make sure that the trucks arrive at the same order in which they were loaded at the asphalt plant. C. Ensure that no bunching of trucks occurs at the paver, with several trucks waiting to dump their loads. D. Match lay-down rate to material delivery rate. NOTICE Temperature problems may occur will before the time the material is loaded into the trucks, or during the trip to the paver. They can be the result of temperature variations at the plant. If this is not addressed prior to delivery of material to the paver, waviness in the he mat will be the result. 4-13



"W" Weight of Screed For weight of screed force "W" to remain constant, the weight of the screed or the downward pressure exerted by the screed on the paving material should not change. The weight of the screed is measured in pounds per square inch.

Figure 4.05a

Members of the paving crew climbing on and off the screed will have some affect on the weight of screed force. The primary factor affecting this force is changing the width of the screed. Extendible screeds weigh the same whether they are fully retracted or fully extended. The difference is the wider the extension of the screed the greater the surface area of paving material to support. An extended screed has fewer psi, which means less compaction, causing the screed to raise.



Quality of Base Being Paved There are factors other than the four main forces that can have an effect on the quality of the mat. An important one is the quality of the base to be paved. It makes more sense to build smoothness from the base up, than to try to smooth a road in the last lift of paving. However, on overlay paving jobs we have to work with what we have. Remember that a mat which appears smooth immediately behind the paver, may actually contain areas of considerably varying thickness of material as a result of undulations in the base being paved. Due to the principle of "Differential Compaction" high spots will not compact as much as the low, therefore allowing some of the irregularities to be rolled back onto the mat. To minimize this problem, lay a leveling course in the low spots or pave multiple lifts to average out the irregularities.

Figure 4.06

4-15



Rolling Techniques A well laid mat can end up with a poor ride quality if proper rolling methods are not followed. Consult your compaction equipment manufacture's manuals and handbooks on compaction techniques.

Controlling Mat Quality The primary purpose of the asphalt paver is to place a smooth mat of material. The primary function of System Five is to control the vertical position of the screed in relation to the surface being paved. Automatic grade and slope control systems can help tremendously in controlling mat smoothness but mat quality is also dependent on the following factors: A. B. C. D. E.

Non-Stop, Continuous Operation of Paver Constant Speed of Paver Truck Exchange Head of Material Mix Characteristics 1. Gradation 2. Segregation 3. Mix Temperature F. Screed Compaction G. Quality of Base Being Paved H. Rolling Techniques NOTICE

4-16

Changes in any of these factors will cause a change in mat thickness, density, surface appearance and mat quality. If changes must be made, make them as gradually as possible. Abrupt changes in any of the above factors will produce rapid changes in mat thickness, adversely affecting mat quality.


Chapter 5 : Getting Ready to Pave

Getting Ready to Pave

Figure 5.0

This chapter is designed to get the paving crew started using System FiveTM. The job application and the desired results will determine what type of non-contacting controls should be used; i.e. sonic, slope, laser and SAS. The components should be mounted on the paver and then the paver itself must be properly set up. 5-1


Chapter 5: Getting Ready to Pave

Connect the cables into the Control Box:

Figure 5.01

NOTICE Due to different types of machine configuration, your cable connections may vary.

Machine Setup To start paving with System FiveTM, set up the paver just as you would under manual control. Place the screed on blocks or lath set for the desired paving thickness. Make sure you account for material compaction. 5-2



Figure 5.02a

Center the tow point cylinders to maximize travel in raise or lower directions. You can use the jog switch on the System FiveTM Box (Power must be on) or the switch provided with the paver.

5-3 Figure 5.02b



Using the manual thickness adjustment cranks or hand cranks on the paver, null the screed and set the proper angle of attack. Next, turn on the auger feeder controls to place the asphalt in front of the screed.

Figure 5.02c

5-4



Sonic Tracker Setup When installing and positioning the Sonic Tracker IITM, first connect the coil cord to the Tracker. Then bolt the Tracker to the bracket, and visually check to get the Sonic Tracker plumb. Make one wrap of the coil cord around the "L"-Bar. This will act as a strain relief for the connector on the Tracker. Be sure the coil cord snap hook is in place and secure.

Figure 5.03


5-5


Control Box Setup - Elevation Once the Sonic Tracker has been positioned over the reference, the Control Box can now set the Tracker On-Grade. Flip the power switch to the on position press and hold the survey button for 1 second until the box beeps and the green OnGrade Bar is displayed.

Figure 5.04a

Next, make the display read the same number as depth of mat to be laid. Press and hold the "Set" button with one hand. With your other hand, turn the grade adjustment knob to change the display to the height of the blocks under the screed. Release the "Set" Button and the value will be saved.



Using Set will not change the existing mat thickness, it only changes the reference number viewed on the display.

Figure 5.04c

Press the Red Button and the Red LED will light up. You are now in automatic mode and can begin paving.

5-7



After you begin paving it is important to check the mat depth to insure the desired thickness is being laid. The blocks initally placed under the screed may cause the mat to be too thick or thin. Check the mat several times to get an average before making any corrections.

Figure 5.04d

5-8



If a 2.50 inch mat is required, but a 3.0 inch mat is being laid, then an adjustment is necessary. You must first get the box to display the same number as the mat depth. Press and hold the "Set" button with one hand. With other hand turn grade adjustment knob to read 3.0 inches. Press the red auto button to put the system back in automatic control.

Figure 5.04e

5-9



With the paver moving and in auto, slowly dial the display from 3 inches down to 2.5 inches. How fast you turn the knob depends on how smooth you want the transition to take place. Highways require gradual changes, parking lot require quick changes. The display should now read the depth of the mat being laid.

Figure 5.04f

5-10



Control Box Setup - Cross Slope The slope sensor should already be mounted on the transverse beam of the paver. The sensor can talk to both control boxes, but only one at a time. The sensor communicates to the Control Box through the cable.

Figure 5.05a

To pave using cross slope you must first calibrate the slope sensor, to the screed. Find a smooth area where the screed can rest evenly across its entire surface. Using a laser, a Smart Level, or a slope board, that itself has been calibrated, check the cross slope and direction of fall of the ground.



Now place the screed on the ground and null it out. Flip the power switch to the On position and push the Slope Mode Button. The yellow LED next to the cross slope symbol will illuminate.

Figure 5.05c

To find out the slope and direction of fall the slope sensor thinks the screed is resting on, push the survey button for 1 second to lock sensor On-Grade. If the box is displaying and On-Grade bar and a slope value that is identical to the laser or Smart Level then you can begin paving. Make sure to push the Auto Button.

5-12

Figure 5.05d



If the slope displayed in the box does not match the surface, then the sensor must be calibrated. Press and hold the "Set" button with one hand. With your other hand, turn the grade adjustment knob to change the display to match the slope of surface. Release the "Set" button and the value will be saved.

Figure 5.05e

NOTICE Using Set will not change the slope, it only changes the slope value viewed on the display. Press the Red Button and the Red LED will light up. You are now in Automatic Mode and can begin paving.

5-13



Once the slope sensor is calibrated and you are ready to begin paving, you may find the existing surface does not have the same slope as the finish design. In order to produce a smooth transition, begin paving at the existing slope and slowly turn the grade adjustment knob to change the cross slope to the correct percentage.

Figure 5.05f

If a smooth transition is not required, then dial in the desired slope and begin paving.

5-14


Chapter 6: Tracker Placement

Tracker Placement Raise or lower the tracker bracket to position the tracker at the proper height above the grade reference. The tracker has a total working range of 14 to 55 inches. For paving applications the recommended working height would be from 14 to 24 inches. At 55 inches the sonic footprint would be very large and the tracker may pick up an undesired reference. The tracker also compensates for temperature changes only within the bail range. Placing the tracker too far from the reference may not allow for accurate temperature compensation.

6-1 Figure 6.0



Position the "L"-Bar horizontally so the tracker will be over the reference. For example, when tracking a curb and gutter, place the screed or extension flush with the edge of gutter and slide the "L"-Bar so the Tracker is over the lip of the gutter.



The "L"-Bar can also be mounted to a bracket on the screed extension. This would work well in applications where the reference will not be a constant width and requires the extension to be moved in and out. Mounting to the extension will make it easier to keep the tracker over the reference.



When tracking a curb and gutter, keep the tracker 14 to 24 inches above the lip of gutter. If the tracker is placed too high, the sonic cone may pick up an unwanted surface, such as the face of the curb.

Figure 6.01c

For joint matching and tracking sub-grade or most surfaces keep the tracker between 14 to 24 inches. A good rule of thumb is to set the tracker about 18 inches from the reference.

6-4 Figure 6.01d System FiveTM Paver Operator's Manual


Temperature and atmospheric conditions will have an effect on the speed of sound. In paving applications you can get a dramatic and rapid change in air temperature. A temperature bail is attached to the tracker to compensate for these variations. If you are on a job where there are high winds and/or large temperature fluctuations, lower the tracker closer to the reference.

Figure 6.01e

6-5



If a mechanical ski with an elevated string or wire is being used, make sure the string/wire reference is a minimum of 4 inches above the ski. When paving with a mechanical ski through super elevations the ski will tend to pull away from the paver and may even tip to one side. Elevating the string at least 4" will insure the ski stays out of the working window. It is also important to place the tracker in the center of the ski to maximize the averaging length. If you are using a 30' ski, then the sensor should be placed 15' from the end of the ski. For every 1' positioning error from the center of the ski, you lose 2' effectivity of the ski. An example of this would be if the sensor is moved foreword or backward 2 1/2 ' (12 1/2' from the end) you are using a 25' ski.

Figure 6.01f

6-6



Some jobs may require the mat be laid to a specified elevation. In an application like this an elevated stringline or wire may be set up. As was mentioned in the operation section, the sonic tracker has a built in working window that will prevent the screed from diving if the tracker loses the stringline reference. Position the tracker over the stringline and set the distance between 18 and 24 inches.

Figure 6.01g

6-7



Sometimes the surface to be paved contains pot holes or the surface is too broken up to use as a joint match reference. Setting an elevated stringline is too time consuming especially for small, divided up projects. In these applications, surface stringline would be a good alternative. (See section on Setting Surface Stringline).

Figure 6.01h

6-8



We've discussed how far a tracker should be positioned from the reference, now we need to look at where the tracker should be placed in relation to the screed. As a tracker is moved closer to or further away from the screed, the response of the screed to an elevation correction changes. A rule of thumb is to place the tracker about 1/3 to 2/3 the length of the tow arm forward of the screed pivot point.

Figure 6.01i

If the tracker is not placed between these points then incorrect screed responses could result. Let's look at a couple of examples. If the tracker is placed directly at the screed pivot point, you can see exactly where the screed is relative to the grade reference. This is good, but the problem is we have no feedback from the tow point cylinder, which is what we are using to make the grade control changes.

6-9 Figure 6.01j System FiveTM Paver Operator's Manual


If the tracker gets closer to the reference, it sends a raise correction signal to the valve and the tow point cylinder begins to move up. Because the screed floats it does not react immediately to the tow point movement so the tracker continues to send raise correct signals to the valve. By the time the screed gets to grade, (approximately 3 tow arm lengths) the tow point cylinder has moved too far causing the screed to continue raising. The tracker senses this over correction and sends a lower signal to the tow point cylinder, repeating the whole process in the other direction. Therefore, with the tracker mounted at the screed pivot point, long waves in the mat will be produced because there is no feedback from the tow point cylinder to the screed.

Figure 6.01k

6-10



To compensate for no tow point feedback let's place the tracker directly at the tow point where we are making the grade corrections. At this point we can keep the sonic tracker an exact distance from the grade reference. Any tracker elevation changes will cause the tow point cylinder to move right away. The problem with the tracker placed here is we have no feedback from the screed.

Figure 6.01l

If any of the forces acting on the screed change then the screed will rise or fall without the tracker sensing the movement. For example if the amount of material in front of the screed was decreased, the head of material force "M" also decreases and the screed would begin to fall. The sonic tracker would keep the tow point cylinder on grade, but not the screed since there is no feedback.

6-11 Figure 6.01m System FiveTM Paver Operator's Manual


The best place for the tracker is in the 1/3 to 2/3 zone, but where do we position the tracker within that area? That depends on what end result of paving you are trying to achieve. As the tracker is moved further back towards the screed it becomes more reactive. At the 1/3 point a 1/4 inch correction at the tracker will cause a 3/4 inch correction at the tow point. Another way to look at it is the "Net Tow Arm Length". A paver with a 9 foot tow arm and no sonic tracker will take 27 feet (9 feet x 3 tow arm lengths) to see 96% of the elevation change. If a tracker is placed at the 1/3 point or 3 feet in front of the screed pivot point then the paver must only move 9 feet (3 feet x 3 tow arm lengths) for 96% of the elevation change. The tracker is measuring the distance to the reference so its position along the tow arm becomes the net tow arm length. A more reactive screed would be beneficial for applications where it is important to match the reference such as tracking a curb and gutter or matching a joint.

6-12

Figure 6.01n



As the tracker is moved further forward the screed becomes less reactive. A tracker placed at the 2/3 point and looking for a 1/4 inch correction will only cause the tow point to move 3/8 inch. The net tow arm length is now 18 feet (6 feet x 3 tow arm lengths). This would be a better tracker position for applications where smoothness is desired such as mainline paving or when using a mechanical or noncontacting (SAS) ski.

Figure 6.01o

6-13



Notes

6-14


Chapter 7: Stringline

Stringline Setting Surface Stringline Surface Stringline is a great replacement for a contacting averaging ski, or where no reference is available or practical. The purpose of a ski is to average out the irregularities of the surface being paved. Although a good idea in principle, averaging skis seldom work well in practice. They are bulky, complex, cumbersome and get broken easily. When they are working they still only average over their length. Surface Stringline is better. As a Surface Stringline is stretched over the ground it levels out the high places and bridges the low, creating a very natural average over a distance as long as 500 feet. Since the Sonic Tracker IITM is non-contacting, it can track Surface Stringline without deflecting it, producing an extremely smooth surface. Additionally, the smoothness of the surface you will get from Surface Stringline is verifiable before you begin paving. Just sight down the string and you can see how good the job will be. If there will be problem areas, mark the spots and either fix them ahead of time or use the marks as a "I told you so" for future reference. You can also use the same Sonic Stringline as a steering guide.



Position the tracker 14 to 18 inches above the stringline.

Figure 7.01a

NOTICE It is important to use a stringline with a diameter at least 1/8" thick. The sonic tracker can detect a smaller diameter stringline, but when stretched on the surface to be paved the surface below the stringline will be within the working window so you want to make sure you have a strong return signal.

7-2



To setup surface string, simply drive a concrete nail into the existing surface to be overlaid and tie the stringline to the concrete nail.

Figure 7.01b

7-3



Roll out the stringline to the desired length. Pull tight and secure to another nail at the opposite end. The tightened stringline will rest right on top of the existing surface. When the sonic tracker sends out a sound wave, the first thing the tracker sees will be the reference stringline.

Figure 7.01c

Since the stringline has been pulled tight, any small variables in the existing surface will be bridged. You now have 500 ft. ski.

Figure 7.01d

The operator may use the surface stringline for steering and grade control. Trucks and other traffic can drive right over the top of the surface string with out causing any grade control problems or damage to the reference 7-4

The surface stringline is a verifiable grade reference, what you see is what you get. Any potential problems can be pointed out to the inspector before you pave. Try it, it really works! System FiveTM Paver Operator's Manual


Setting Elevated Stringline On some projects the asphalt must be laid to a specified elevation. For this application an elevated stringline must be set. The stringline will usually be set up at a 1' or 2' "hike up" from finished grade. The stringline is set referencing hubs or lath placed by the surveyor.

Figure 7.02a

Sonic Stringline provides an inexpensive, easy to set up, continuous reference that takes the best advantage of the non-contacting feature of the Sonic Tracker IITM. By taking a few minutes to set up a stringline the Tracker can transfer grade to the paver 39 times per second! The stringline also becomes a great visual reference for the job. Any mistakes in a hub elevation can be quickly spotted by just sighting down the string.



NOTICE Although Topcon’s Sonic Tracker will work with many sizes and types of stringline, for best results werecommend an 1/8 inch diameter nylon stringline. Using steel wire or a plastic coated stringline with a smooth surface is not recommended. If the Tracker will track the ground, but will not track a 1/8 inch diameter stringline, clean or replace the transducer.

1. Place the Sonic Grade Clips on stakes and drive the stakes approximately 6 to 8 inches away from, but in line with, the hubs (Do Not disturb the hubs).

7-6 Figure 7.02c System FiveTM Paver Operator's Manual


2. Using an anchor pin at each end, roll out the Sonic Stringline the length of the working area and pull the stringline tight. 3. After the stringline has been pulled tight, place it into the ‘fingers” of each Sonic Grade Clip.

Figure 7.02d

4. Decide what the Sonic Stringline hike-up (the distance from Finished Grade to the Sonic Stringline) should be: in this case, 2 feet. Make a cut/fill lath using a lath and a Topcon Cut/Fill Decal. 7-7



Measure, from the bottom of the lath, the desired hike-up and make a mark at that point. Place the Cut/Fill Decal on the lath with “0” on the point you marked.

Figure 7.02e

5. Next, set the cut/fill lath on the hub and read the cut or fill from the grade stake next to the hub. Adjust the clip up or down until the stringline crosses the cut/fill lath at that point. A cut of .25 feet

• The stringline is now set to 2 feet above finished grade.

• Repeat this process at each station before starting to pave.

•

Setting Stringline to Projected Slope Jobs with slope transitions or super-elevations must have the stringline set to the “projected slope”. Failure to do this will produce an elevation error at the edge of the road as the slope is changed. To set the stringline to the projected slope, first set up the string at the desired hike up as shown in the previous pages. Next, raise or lower the stringline to compensate for the % slope and the distance from edge of the road to the stringline. [RISE = (RUN)(%)]. If the road is rising away from the stringline, the stringline will need to be lowered. If the road is sloping down from the stringline, the stringline will need to be raised. This adjustment is needed at each station. • Example: 2.0% Cross Slope with 2 feet offset.

Figure 7.02i

• Example: 3.0% Cross Slope with 2 feet offset.

Figure 7.02j

On some jobs, it may be more practical to secure the stringline directly to the grade stake next to the hub. First, mark the lath with a 2 or 3 feet “hike up” or boot” above grade, just as you would to check grade with an eye level or pulling a string across the street.

7-11 Figure 7.02k System FiveTM Paver Operator's Manual


Secure an anchor pin at each end of the stringline and pull the stringline tight. At each station, staple or ty-rap the stringline directly to the witness lath so the stringline is at the desired hike-up.

Figure 7.02l

Due to the height of some stakes the Tracker may need to be raised or the tops of those stakes may need to be cut off.

• Making a Grade Verification Lath Verifying grade requires measuring the distance from the asphalt to the Sonic Stringline. Because the hubs are offset from the edge of road and the Sonic Stringline is a predetermined “hike-up” above Finished Grade, a simple tool called a “Grade Checking Lath” can be constructed. This can be easily done using lath, a level bubble and simple hand tools. In this example assume that the hub offset from the edge of road is 1.5 feet and that the “hike-up” is 2.0 feet. Construct a Grade Checking Lath as shown below.

7-13 Figure 7.02m System FiveTM Paver Operator's Manual


• Verifying Grade To verify grade, set the Grade Checking Lath on the newly laid mat edge so that the level bubble extends over the Sonic Stringline shown below.

Figure 7.02n

7-14

Tilt the Grade Checking Lath until the level bubble is centered. Finished Grade is correct when the level just touches the Sonic Stringline. System FiveTM Paver Operator's Manual

Chapter 8: Smoothtrac® (SAS) Set Up

Smoothtrac® (SAS) Set Up Topcon's Smoothtrac® is a non-contacting averaging system that uses multiple sonic trackers to smooth out the bumps and dips in a mat surface. The non-contacting design allows full maneuverability of the paver when turning around, backing up or passing over obstacles without lifting or removing the beam. The screed man can adjust mat thickness on the control box while standing on the screed. The Smoothtrac® is mounted to the tow arm of the paver, and connects to System FiveTM with the same coil cord used for the Sonic Tracker.

Figure 8.0

8-1



When mounting the SAS to the paver there are a few simple steps to follow First, if the ski is not in one piece, connect both halves together.

Figure 8.01a

Next, mount the "L" bars to the brackets on the tow arm. The outside "L" bar can be attached so it points up or down. The position will depend on how tall the tow arm is off the ground. For pavers with a tall tow arm, mount the "L" bar in the downward position. For shorter tow arms, mount in the upward position. Place locking collars on bars and adjust so they are parallel with one another before tightening with an Allen wrench. This will allow the ski to move freely when adjustments need to be made without falling off.

8-2



Bend "L" bars so they are aligned in the same position and fold inwards so they are close to the paver. Make sure clamp handles are loose so bars can move.

Figure 8.01b

Lift ski and slide over "L" bars. Adjust the ski so it is approximately 2 1/2 feet off the ground. Slide the locking collar up to the ski and lock in place. Helpful hint, the ski will be easier to mount if the end beams are folded in. Bend "L" bars so they are aligned in the same position and fold inwards so they are close to the paver. Make sure clamp handles are loose enough so bars can move.

8-3



Lower each of the Tracker hangers on the SAS and mount a Sonic Tracker using the "L" handle bolt. An extra washer may need to be added so the "L" handle does not block the cable connection.

Figure 8.01c

Connect the SAS coil cable to each tracker to the Sonic Tracker coil cord. Make sure to loop the coil cable through the "U" hangers to keep it from getting damaged. Don't forget to install temp bails before paving!

8-4 Figure 8.01d



Positioning the SAS The SAS should be positioned so the Sonic Trackers are 14 to 24 inches from the grade reference. As with single tracker operation, the "lower the better" is a good rule of thumb for paving applications. This will help minimize the variable temperature conditions that can cause erratic signals. The beam does not have to be perfectly level because each tracker averages the distance to the reference individually.

Figure 8.02a

With SAS be careful when the screed is raised, that the front tracker does not hit the ground. If needed the tracker bracket can be folded back when raising the screed to keep the tracker from hitting obstructions.

8-5



The trackers can be placed so all four are over the reference, or the back tracker can be set over the freshly laid mat. The best method is the one you are presently using or the one in which you are most comfortable.



In some applications the grade reference outside the screed extension may not be in satisfactory condition, such as the shoulder of a road or the broken and warped edge of pavement. Traditionally the screedman would manually adjust mat thickness on that side of the paver. The non-contacting SAS can be set up over the screed so full automation can be used. The first three trackers will reference the existing grade and the back tracker will reference the mat just laid.

Figure 8.02c

8-7



When paving with the screed extensions out, there may be a large "head of material: which could be picked up by the Sonic Tracker. If this happens determine how far forward the tracker must be placed on the beam to not pickup the mix and drill a new mounting hold for the tracker hanger. The SAS coil cable will easily reach the tracker.

Figure 8.02d

8-8



Placement of Sonic Averaging System The center connection point of the SAS is the balance point. The position of the balance point to the tow arm is very critical. By moving the balance point, the performance of the system is greatly affected. The balance point of the beam should be located 1/3 to 2/3 the distance from the pivot point of the screed to the tow point cylinder. Placing the balance point closer to the 2/3 point (near the tow point cylinder), will cause the system to have a slower reaction time. This would be good for smoothness or for mainline paving. Placing the balance point near the back 1/3 (closer to screed) will cause the system to have a faster reaction time. This would be good for a combination of smoothness and joint matching. To determine where to position the SAS on the paver, start by measuring the length of the tow arm. Divide the total length by three. This will give you the placement of the balance point of the SAS on your machine.



Once the SAS has been installed, the System Five control box will automatically configure for SAS when powered on. The box will check to see how many trackers are connected and average over that amount. Getting the System Five Box ready to pave is the same as with one tracker. 1. Block screed for required mat thickness 2. Center hydraulic rams 3. Null screed and turn on augers to place material in front of the screed 4. Place trackers over reference 5. Push survey button on Box to lock trackers On-Grade. 6. Push and hold set button while dialing in mat depth. 7. Put Control Box in Auto and begin paving.

Figure 8.03b

NOTICE

8-10

It is not necessary to start paving in manual as is traditionally done when using a mechanical ski. If the setup procedures are followed correctly, paving with the SAS can and should start in automatic. System FiveTM Paver Operator's Manual


The SAS system has been designed to discontinue operating when one of the Trackers fails. When a failure occurs, the control box will flash "ERR" followed by a number from 1 to 4. The number represents the Tracker which failed, making troubleshooting easy and fast. To reset the control box once a new tracker has been installed, or if the tracker has been removed and only three trackers will be used, turn the power off then on. The control box will reconfigure to the number of trackers. Changing the number of trackers may change the average distance. Resurvey the Control Box to lock SAS On-Grade. Once one of the Trackers has been eliminated from the averaging, the balance point of the beam will have changed. If the faulty Tracker is not replaced the beam will need to be repositioned to adjust for the new balance point. It is strongly recommended, if the first or last Tracker fails, to replace it with one of the Trackers from the middle of the beam. This will insure that the balance point is not outside of the 1/3 to 2/3 rule. NOTICE A number reading of "1" could mean the first or last Tracker has failed depending on which side of the paver the beam has been mounted. The SAS cable is labeled with numbers at each connector for easy identification.

Chapter 9: Applications

Applications What type of controls you should use for paving depends on what result is required for the finish product. Some projects are looking for smoothness and improved rideability. Others are concerned with mat thickness and some require the new asphalt to match curb and gutter or existing grades. Topcon's System Five is very versatile and can be used in all these applications. The following are a few examples of what controls might be used and how to set them up.

Paving City Streets with Sonics When paving city streets the general requirement is to lay a mat that is so many inches above the base at the centerline and to match curb and gutter. For this application sonic control will be used on both sides.

Figure 9.01a

NOTICE Before paving make sure the machine is properly setup, cross slope is calibrated and trackers are set in the correct position. (See Chapters - Getting Ready to Pave & Tracker Placement.) System FiveTM Paver Operator's Manual

9-1


Position right Tracker over lip of gutter and left Tracker past the centerline on the base material.

Figure 9.01b

Turn Boxes on, then "Survey" and "Set" the displays to read the depth of asphalt to be laid.

Figure 9.01c

Put boxes in Automatic and begin paving. Check depth of mat at centerline and verify joint is matching at lip of gutter. After compaction make necessary adjustments on the Control Box. NOTICE If the road width varies, it will be easier to keep the Tracker over the gutter if the Tracker is mounted to the extension on the paver. 9-2



To pave the other side of the road, position the left Tracker over the lip of the gutter and place the right Tracker over the new mat.

Figure 9.01d

"Survey" boxes On-Grade and "Set" the displays to read the depth of asphalt to be laid. Put boxes in Automatic and begin paving. Check to make sure joints are matching after compaction.

9-3



Paving City Streets with Cross Slope Another option is to pave the street using cross slope and sonic control. The Tracker is positioned over the lip of gutter on one side and cross slope is dialed in for the crown on the other. This method may have to be modified due to the fact that in many cases the curbs may be poured at different elevations across the street. Even though the curb was poured out of tolerance, it may have passed inspection and the asphalt needs to match the curb and gutter. If the curbs are at different elevations, it is impossible to pave a typical design slope on both sides of the street. A cross section design of a 36 feet wide street with a 2.0% slope will produce a .36 feet rise at centerline.

Figure 9.02a

9-4



If the curbs are at different elevations, a .36 feet rise at centerline will produce incorrect slopes.

Figure 9.02b

When System FiveTM is used to pave a true 2.0% slope, the crown of the street will not be at the centerline.

Figure 9.02c

9-5



To pave from uneven curbs using slope control choose the side of the road with the highest curb and position the tracker over the curb. Set the other side for the desired cross slope and begin paving.

Figure 9.02d

To keep the centerline in the middle of the road, the second pass will have to be set up with Sonic Control on each side of the paver. The left Tracker will match the lip of the curb and the right side Tracker will follow the new mat. The cross will not be consistent on this side of the roadway, but the joints will match.

9-6 Figure 9.02e System FiveTM Paver Operator's Manual


The curb elevations can be easily spot checked using a fast leveling RL-HB rotating laser. Set the laser at the lip of one curb, then use the detector and a folding rule to take a reading on the other curb. Spot check every 25-50 feet by just moving the laser.

Figure 9.02f

Paving Streets Through Intersections As you pave city streets you will come upon an intersection where the curb will not continue. There are a couple of methods for controlling grade through the intersection. Method 1 For this method the base of intersecting road will be used as the reference. With both sides in Elevation Control, pave to the intersection.



Just before the right Tracker reaches the end of the curb, put the Control Box in Manual Mode by pushing the Red Auto Button.

Figure 9.03b

Without stopping, continue paving until the Tracker is on the base material of the intersecting road. "Survey" the Tracker On-Grade on the new reference and put back into Automatic Control.

Figure 9.03c

9-8



Pave through the intersection and just before the Tracker reaches the curb on the other side, put the Control Box in Manual mode.

Figure 9.03d

Without stopping, continue paving until the Tracker is back on the lip of the curb. "Survey" the Tracker OnGrade and put back into Automatic Control.

Figure 9.03e


9-9


NOTICE You may find after surveying the Tracker on the curb that the number has changed slightly from the curb on the other side of the intersection. This is due to the different depth of the base below lip of curbs. While paving, slowly dial the display back to the previous number. Method 2 Sometimes the base of the intersecting road is too rough to use as a reference. A great alternative is to use a simple piece of stringline. Take a section of 1/8" diameter string and nail or secure it to the curb. Pull the string tight through the intersection and nail or secure it to the other curb. If the intersecting road has a crown, hike the stringline up in the middle of the road to place the string at the proper height. A hub or a stake with a piece of wire to hold the stringline works fine.

9-10

Figure 9.03f



This constant reference will give you complete control through the intersection and will also insure that you tie in perfectly to both curbs.

Paving Intersections with Cross Slope When paving with slope, intersections do not require any adjustments if the "mainline" cross slope does not change. If the slope does change, then a combination of slope and Tracker should be used.

Figure 9.04a

9-11



Put the slope side of System Five Box in Manual just before the slope of the intersection begins to change. Switch from slope to elevation control on the box and "survey" the Tracker On-Grade.

Figure 9.04b

Figure 9.04c

9-12



Pave through the intersection with the Sonic Tracker in Automatic. Upon reaching the end of the intersection put the System Five Box back in Manual and change to slope control and survey the slope to get an On-grade signal.

Figure 9.04d

9-13



Figure 9.04e

Figure 9.04f

NOTICE You may find after surveying the slope that the number displayed is not the same as the desired cross slope. This will occur if the surface being paved is not also at the desired slope. To get back to the correct slope continue paving in automatic and slowly dial the display to the desired slope. Failing to survey when changing back to slope control could result in a bump in the mat. 9-14


Chapter 10: Maintenance

Maintenance This section contains information regarding preventative maintenance and daily care of System FiveTM. Also included are:

1. Cleaning procedures for the Sonic Tracker IITM Transducer. 2. Replacement procedures for the Sonic Tracker IITM Transducer.

Preventative Maintenance & Daily Care A good preventative maintenance and daily care routine will prevent many problems before they occur. The most important part of daily care for System FiveTM is to clean it and keep it free of debris, and to thoroughly dry removable components (Sonic Tracker IITM, the Control Box, and cables) before storing them in the Carrying Case. In addition, the following procedures will ensure trouble free operation: 1. Keep the Carrying Case clean and dry. Do not leave it open and exposed to the elements. Clean and dry all components prior to placing them into the Carrying Case. 2. Be sure cables left on the paver are attached to protective connector caps, not in use. Water accumulating on the connectors can cause electrical shorts. System FiveTM Paver Operator's Manual

10-1


3. Do not use high pressure spray water steam cleaner hoses directly on cables and components. The components can be used in the rain or light spraying. 4. Check the Sonic Tracker IITM Transducer daily to make sure the Filter Foam and Transducer are clean and free of debris. If the Filter Foam is clogged with dirt, replace it. If the Transducer appears to be covered with debris and performance is being affected (see Sonic Tracker IITM in Chapter 2: Operation) clean or replace Sonic Tracker IITM Transducer using the steps listed later in this chapter.

10-2



Transducer Cleaning (Sonic Tracker II) NOTICE This procedure is not meant to be a regular maintenance procedure. Cleaning of the Transducer should only be performed when Transducer contamination is suspected or evident. Over cleaning of the transducer will result in shortened Transducer life and/or water damage to the Sonic Tracker. 1. Hold the Sonic Tracker IITM in an UPRIGHT position (this will prevent moisture from inadvertently entering the Sonic Tracker). 2. Mix a mild detergent with water and place the mixture in a spray bottle (use Simple Green® where available.) 3. With the Sonic Tracker IITM upright, thoroughly spray the Transducer with the detergent solution. 4. Once the Transducer has been sprayed with the detergent, fill the spray bottle with clean water and rinse any residual detergent off of the Transducer. 5. Allow to thoroughly dry. If the ability of the Sonic Tracker IITM to "see" a sonic stringline continues to be impaired, the transducer may be damaged and needs replaced. 10-3



Transducer Replacement Procedure (Sonic Tracker II) NOTICE If the Sonic Tracker II is experiencing erratic or inconsistent readings, Transducer contamination should be considered first before assuming any other type of failure. The most common sign of Transducer contamination is the ability of the Sonic Tracker IITM to “see” the ground, but not a Sonic Stringline.

Sonic Tracker II Transducer Replacement 1. Remove and discard the Filter Foam (a new Filter Foam is provided in the Transducer Replacement Kit). Figure 10.01a

10-4

2. Remove the four screws and the black Retaining Ring. There are four replacement screws supplied in the Transducer Replacement Kit, but it is advisable to use the original screws and keep the four supplied in the kit for replacements in the event one or more are lost). Remove and discard the “O”-Ring (a new “O”-Ring is supplied with the Transducer Replacement kit). Figure 10.01b System FiveTM Paver Operator's Manual


NOTICE Always remove and discard used “O”-Rings. Used “O”-Rings will be distorted and may loose there elasticity due to weather or exposure to diesel fumes. 3. The Transducer can now be gently pulled out. Use a SMALL pair of dikes to gently cut the Ty-Wrap then remove the small wire connectors from their tabs. NOTICE When cutting the Ty-Wrap, be careful not to cut or damage the wires.

Figure 10.01c

10-5



4. Place the wire connectors of the new Transducer firmly on their tabs (the gray wire connector is placed on the elevated tab). Place the Ty-Wrap in the slot next to the elevated (gray wire) tab, tighten and trim. DO NOT pinch the wires.

Figure 10.01d

5. "Feed" the wires back up into the Sonic Tracker IITM and seat the Transducer into place (the two wire tabs have to sit down into the extra deep area of the recess). Place the new “O”-ring around the Transducer and seat firmly between the Transducer and the Sonic Tracker IITM Transducer recess.

Figure 10.01e

10-6



6. Place the black Retaining Ring over the Transducer assembly with the beveled edges out and the flat surface against the Sonic Tracker IITM base. Line up the holes for the mounting screws (the mounting screw holes are set to an irregular pattern. This ensures the retaining ring will only lineup with the mounting holes one way). 7. Start the mounting screws into the holes and tighten each until firm. DO NOT OVER TIGHTEN. Use a cross (X) pattern to tighten screws.

Figure 10.01f

NOTICE Over tightening may distort the Transducer metallic material and may crack the Retaining Ring. Use of the “O”-Ring assures tightness while preventing vibration from loosening the Mounting Screws.

10-7



NOTICE DO NOT use Loctite® on the mounting screws. Loctite® will attack the plastic retaining ring. 8. Make sure there are no visible wrinkles in the metallic surface inside the Transducer. If distortion is evident, repeat Steps 5 through 8. 9. Place a NEW Filter Foam over the Transducer. The Sonic Tracker IITM is now ready to return to operation.

11-1


Control Box Symptom 1 •

"The Control Box LCD does not display."

Probable Cause • No power to the Control Box. 1. Check that the machine power is on and all switches for automatic control on the paver are in the proper position. 2. Check that all cables are properly and securely connected to the System Five™ Box and the paver. Make sure cables are not still connected to Control Box bracket. 3. Disconnect cables and inspect them for damage or contamination. Clean all connections with an electrical contact cleaner. NOTICE Do not use electrical contact cleaner to clean the Tracker's transducer. 4. Swap Control Boxes from left to right side. 5. For System Four™ bypass Junction Box by plugging coil cord from paver to J-Box directly into Control Box.

11-2




"Control Box LCD shows 'Error '"

Figure 11.0

Probable Cause • No communication with the sensor selected. 1. Check that all cables are properly connected to System Five™ Control Box and sensors. 2. Disconnect cables and inspect them for damage or contamination. Clean all connections with an electrical contact cleaner. NOTICE Do not use electrical contact cleaner to clean the Tracker's Transducer. 3. If elevation has been selected, one at a time, swap the Sonic Tracker II™ and cables from the opposite side to locate the error.


11-3


4. Refer to Tracker Symptom #1. 5. If slope has been selected, check that slope has not been selected on the other Control Box. Only one box at a time can have slope turned on. 6. Swap slope cable from opposite side. 7. Disconnect cable at slope sensor and connect to other side of sensor to check slope sensor pins.


"Cannot adjust to On-Grade when elevation control is selected."

Probable Cause • Tracker is too close to control reference. 1. Check that the Sonic Tracker II™ is at least 14 inches away from the control reference. 2. Check for unwanted objects within the sonic footprint. 3. Make sure tracker is not positioned in front of a gusty heat source, such as the engine fan exhaust.

11-4

4. Stop the paver, make sure the screed is on the ground and turn the vibrators off. Press Survey and hold for 2 seconds. "IND" will display on the faceplate and a number will be displayed on the LCD. The number should stay constant, or change up and down by a few numbers. If the numbers fluctuate significantly then the Transducer is probably weak or damaged.



5. Check for contamination on the Sonic Tracker II™ Transducer or foam filter. Refer to Transducer and Filter Cleaning and replacement information in the Maintenance and Parts section of this manual. 6. Swap the Tracker with the unit on the opposite side. 7. Averaging may be set too low if tracking an uneven reference. Factory setting is 50.


"The tow point cylinder doesn't move up or down."

Probable Cause • Machine electrical switches are not in the proper position, or hydraulics to the cylinder are not active. 1. Check that all locking pins have been removed and that all hydraulic blocking valves are in the open and correct position for automatic control. Refer to the paver manufacturer's manual. 2. Check that all machine electrical switches and in motion circuits are in the correct position for automatic control. Refer to the paver manufacturers manual. Press the jog switch up and down on the Control Box to make sure there is a current going to the valve. Cylinder should move in the same direction the jog switch is pressed. 3. Check that the Auto Switch is in "Auto" and that the Auto Symbol is illuminated on the front panel.


11-5


4. Disconnect cables and inspect them for damage or contamination. Clean all connections with an electrical contact cleaner. 5. Swap the Control Box with the unit on the opposite side. 6. If a Control Box is replaced make sure the configuration and performance settings are correct. 7. If a cable is replaced make sure it is the right part number. A cable with the incorrect resistor could set the Control Box to have the wrong configuration.

Control Box Symptom 5 • "The tow point cylinder is moving in the wrong direction." Probable Cause

• Machine is incorrectly wired or hydraulically connected. 1. Check that the machine is properly wired and hydraulically connected to the valve. A raised jog switch should make the cylinder go up, lowering the jog switch should make the cylinder go down. 2. Check that the proper cables have been supplied for your machine. 3. For System Four, if "OIN" setting is in the performance menu, make sure it is in the off position. 11-6

4. Make sure the screed lift cylinders are in the float position and not supporting the screed. System FiveTM Paver Operator's Manual


Control Box Symptom 6 • "The tow point cylinder is moving 'too fast' or 'too slow." Probable Cause • The paving machine's hydraulic flow

adjustment is incorrect, or the control box Valve Offsets or Gain Adjustments are not correct. 1. Refer to paver manufacturers recommended flow adjustment setting for the time it takes the hydraulic cylinder to complete a full stroke of travel. Typically between 12 to 15 seconds. 2. Adjust Gain Performance Settings. Factory setting is 25. 3. Adjust Valve Offsets. Refer to Valve Offset section in the Performance Section within this Manual.

Control Box Symptom 7 • "System intermittently drives the cylinder all the way up or down when tracking a mechanical ski." Probable Cause • Tracker is intermittently picking up signals from the ski. 1. Verify string is at least 4 inches above the surface of the ski. Ski will pull away from the paver and can get in Tracker's Working Window if string is too close. Ski will also tilt to one side when traveling through a super elevation or slope transition.


11-7


2. For a multi-foot ski, make sure "foot spring pin" is not within the sonic footprint as the ski surges back and forth.

Control Box Symptom 8 • "Control Box displays Error and a number from 1-4" Probable Cause • Defective Sonic Tracker or SAS cable. 1. Check SAS cable connections at each tracker. 2. Turn Control Box off and swap tracker showing the error number (1-4) with another tracker on the SAS. (Tracker number is on the cable at the tracker connector). Turn Control Box on to reset SAS. If the error number (1-4) has changed, the problem is the tracker. If the error number remains the same, the problem is the SAS cable. 3. If more than one error number is shown, check trackers individually by plugging sonic trackers directly into the single tracker coil cord to determine if trackers or SAS cable is source of error. 4. The defective tracker or SAS cable should be repaired, but SAS can still be operated without all four. Remember balance point will change if a tracker is removed.

11-8



Control Box Symptom 9 • "Grade lights flash high and low and will not stay on grade." Probable Cause • If problem is only in automatic mode, then hydraulic Performance Settings are incorrect. 1. Verify paving machines hydraulic flow adjustments (time for hydraulic cylinder to travel full stroke) are set to manufactures recommendations. 2. Check that the Valve Offsets are set correctly. 3. Check that the Gain setting is too high. Factory setting is 25. •

If problem is in manual mode, then

1. Verify that temperature bails are clean and securely attached. 2. Verify temperature bail symbol "T" is displayed on face of Tracker. If not clean or replace transducer. 3. Check that Trackers are between 14 and 24 inches from reference. 4. If there are gusty winds, lower Tracker closer to reference. Approximately 14 to 16 inches. 5. Move Tracker away from gusty heat source, such as engine fan exhaust. 6. Verify Tracker is not picking up erroneous signals from undesired reference. Example: Head of material, end gate, shoulder grade or material spillage from hopper.


11-9


7. If using Stringline, verify line is not bouncing. 8. Check to see if Averaging in Performance Menu is set too low. Factory setting is 50. 9. Check Deadband in Performance Menu is not less than 3mm.

Control Box Symptom 10 • "The valve is driving the hydraulic cylinder too far, overshooting grade." Probable Cause • Valve Offset in Control Box are set too high. 1. Lower the Valve Offset value till the sensor no longer overshoots grade. Refer to "Setting Valve Offsets" section in this manual. 2. For Servo and solenoid valves lower the value by 2 to 5 numbers, then check the hydraulic performance. 3. For Proportional valves, lower the value by 10 to 15 numbers, then check hydraulic performances.

Control Box Symptom 11 • "The valve will not drive hydraulic cylinder far enough to get sensor On-Grade." Probable Cause • Valve offsets in Control Box are set too low. 1. Raise the Valve Offset Value till the sensor is driven to grade. Refer to "Setting Valve Offsets" section in this Manual. 11-10



2. For Servo and Solenoid valves raise the value by 2 to 5 numbers, then check hydraulic performance. 3. For Proportional valves raise the value by 10 to 15 numbers, then check hydraulic performance.

Control Box Symptom 12 • "The Control Box displays 'No Signal' when indicate is selected in elevation mode." Probable Cause • Sonic Tracker is reporting no echo. 1. Verify that the Sonic Tracker is ticking. 2. Make sure tracker is pointing at a target with the working range, recommended 14 to 24 inches. 3. Transducer may be dirty or damaged. Refer to the Transducer and Filter section within this manual. 4. Power or ground connection at transducer may be loose. Remove transducer and check wires.

11-11



Control Box Symptom 13 • "The Auto light on the Control Box intermittently flashes on and off." Probable Cause • Sonic Tracker is too far from reference for current atmospheric conditions, or Temperature Cutout is too low. 1. Verify that the Sonic Tracker is positioned 14 to 24 inches from the reference. If there are gusty winds lower the Tracker to 14 to 16 inches from the reference. 2. Move Tracker away from gusty heat source, such as engine fan exhaust. 3. Temperature Cutout is set too low. Factory setting is 7. Refer to Technicians manual.

11-12



Tracker Symptoms 1.

Sonic Tracker will not power on.

2.

Sonic Tracker is ticking, but will not adjust to Grade

3.

Tracker grade lights flash high and low and will not stay On-Grade.

4.

Sonic Tracker is not matching joint or curb.

5.

The Sonic Tracker will pick up the ground, but will not pick up a stringline.

Tracker Symptom 1 • "Sonic Tracker will not power on" Probable Cause • Defective cable or tracker. 1. Check coil cord is plugged in correctly and securely. 2. Inspect Coil cord for any physical damage. 3. Turn Control Box on and watch the tracker lights to make sure they go through the power up sequence. All the lights on the tracker should flash at once followed by a flash of an arrow pointing to the left. The "T" symbol should also be displayed in the upper right hand corner of the tracker faceplate when a Temperature Bail is attached. If the tracker does not go through this sequence then the tracker is not getting power or is defective. 4. One at a time, swap tracker and then coil cord from opposite side to determine the problem. System FiveTM Paver Operator's Manual

11-13


Tracker Symptom 2 • "Sonic Tracker is ticking, but will not adjust to grade." Probable Cause • Tracker is too close to reference, minimum working distance is 14 inches. 1. Tracker is too close to reference point. Position tracker 14 to 24 inches from grade reference. 2. Connect tracker to other side of paver to determine if problem stays with tracker. 3. If problem stays with tracker, clean or replace transducer or foam filter. Refer to the Transducer and filter cleaning and replacement information in the "Maintenance and Parts" section of this manual. 4. If problem does not move with tracker, inspect coil cord for damage and swap with cord from other side.

Tracker Symptom 3 • "Tracker grade lights flash high and low and will not stay On-Grade." Probable Cause • If problem is only in Automatic Mode, then Hydraulic Performance Settings are incorrect.

11-14

1. Verify paving machines hydraulic flow adjustments, time for hydraulic cylinder to travel full stroke, are set to manufacturers recommendations. Typically 12 to 15 seconds.



2. Check Valve Offsets are set correctly. Refer to setting valve offsets. 3. Make sure Gain Setting is not too high. Factory setting is 25. •

If problem exists in manual mode, then Tracker is setup incorrectly or Performance Settings are incorrect.

1. Verify that temperature bails are clean and securely attached. 2. Verify temperature bail symbol "T" is dis played on face of Tracker. If not, clean or replace transducer. 3. Check that Trackers are between 14 and 24 inches from reference. 4. If there are gusty winds, lower Tracker closer to reference. Approximately 14 to 16 inches. 5. Move Tracker away from gusty heat source, such as engine fan exhaust. 6. Verify Tracker is not picking up erroneous signals from undesired reference. Example: Head of material, end gate, shoulder grade or material spillage from hopper. 7. If using Stringline, verify line is not bouncing. 8. Check to see if Averaging in Performance Menu is set too low. Factory setting is 50. 11-15



9. Check that Deadband, in Performance Menu, is not less than 3mm.

Tracker Symptom 4 • "The Sonic Tracker is not matching joint or curb." Probable Cause • Tracker is too far forward on the tow arm. 1. Position the Tracker at 1/3rd the tow arm length (just in front of auger). 2. Gain for tracker may be set too low. Adjust Gain to a minimum of 25. 3. Brackets and L-Bars have not been securely tightened. Also, check for excessive play or slop where tracker is attached to the paver. (Tow arm or end gate.)

Tracker Symptom 5 • "The Sonic Tracker will pick up the ground, but will not pick up a stringline." Probable Cause • Tracker is too close to a reference or transducer is weak. 1. Verify that tracker is at least 14" from the stringline. 2. Smooth, steel wire is not recommended. Use minimum 1/16" diameter string for elevated stringline or averaging ski. Use 1/8" string for Surface Stringline.

11-16



Slope Sensor Symptoms 1. Cross Slope reads "Error" 2. Cross slope drives cylinder in the wrong direction 3. Slope lights flash between raise and lower and will not stay On-Grade. 4. Cross slope will not lock On-Grade. 5. Cross slope being laid is not correct.

Slope Sensor Symptom 1 • "Cross Slope reads 'Error." Probable Cause • Both Control Boxes are selected for slope or have a defective cable. 1. Cross slope operates one side at a time. Verify only one Control Box has been selected for slope. 2. Verify that the slope cable is connected securely and properly. 3. Swap slope cable from other side to check cable.

11-17



Slope Sensor Symptom 2 • "Cross Slope drives cylinder in the wrong direction." Probable Cause • Slope sensor installed incorrectly. 1. Verify the slope sensor is positioned correctly on the transverse beam. "Slope Forward" Decal must be in direction of travel. 2. Check that the machine is properly wired and hydraulically connected to the valve. Raised jog switch should make the cylinder go up, lower jog switch should make the cylinder go down. Refer to the paver manufacturers manual.

Slope Sensor Symptom 3 • "Slope lights flash between raise and lower and will not stay On-Grade." Probable Cause • Incorrect Performance Setting adjustments or a loose transverse beam. 1. Check Valve Offset for proper operation. Refer to "Setting Valve Offsets" section in this manual. 2. Check gain setting. Factory setting is 25. 3. Slope deadband set too low. Increase Slope Deadband. Factory Setting is .075% 4. Check for excess vibration in the Transverse Beam due to poor connection at Tow Arm. 11-18

5. Make sure slope sensor is mounted directly to the Transverse Beam and is not elevated or supported by additional brackets. System FiveTM Paver Operator's Manual


Slope Sensor Symptom 4 • "Cross Slope will not lock On-Grade." Probable Cause • Loose Transverse Beam or incorrect Performance Setting adjustments. 1. Verify that the Slope Sensor is not moving or vibrating when trying to survey slope on grade. 2. Slope deadband setting is too low, factory setting is .075%. 3. Stop the paver, make sure the screed is on the ground and turn the vibrators off. Press Survey and hold for 2 seconds. IND will display on the faceplate and a slope value will appear in the LCD. The number should stay constant or change up or down by a few counts. If the numbers fluctuate significantly then the slope sensor is probably the problem.

Slope Sensor Symptom 5 • "The Cross Slope being laid is not correct." Probable Cause • Calibration in Slope Sensor is incorrect. 1. Calibrate the Slope Sensor as described in “Daily Cross Slope Calibration” in the Function and Operations section. 2. Check that the Transverse Beam is mounted according to the manufacturer’s instructions and that it is not loose or damaged.


11-19


3. Recheck slope using a good reference such as a laser or level. Make sure to wait at least 3 tow arm lengths before checking the slope after a change has been made. 4. If the paver's mat thickness controls have been used then the slope calibration may have to be changed. This can occur after "buying back" cylinder.

11-20



SAS Symptoms 1. When the SAS is connected, control Box displays "Error" and a number. 2. 1 Tracker stops working 3. SAS will not lock On-Grade 4. SAS is not producing smooth surface 5. Tracker picking up head of material

SAS Symptom 1 • "When the SAS is connected, the Control Box displays 'Error' and a number." Probable Cause • Defective tracker or cable, tracker with incorrect code. 1. Verify that all trackers are correctly and securely plugged into the SAS cable. 2. Turn Control Box off and move the Tracker to a different position on the SAS cable. Turn the Control Box on to reconfigure SAS. If error number moved positions with the swapped tracker, then the tracker is the problem. Replace transducer if necessary. Refer to transducer and filter cleaning and replacement information in the "Maintenance and Parts" section of this manual.

11-21



3. Check to see if a Tracker without SAS code is attached to the cable. Verify that the tracker has a SAS compatible decal near the S/N label.

Figure 11.01a

4. Tracker can also be checked by verifying code revision. Turn box off and back on. Watch the temperature bail symbol in the top right portion of the tracker. The "T" symbol will flash a certain number of times, pause and flash again to indicate the revision of its code.

Figure 11.01b

11-22

Example: Flash twice, pause flash twice means the code in the Tracker is 2.2. SAS requires trackers with code of 2.2 or higher. System FiveTM Paver Operator's Manual


SAS Symptom 2 • "A Tracker stops working." Probable Cause • Defective Tracker. 1. Check SAS cable connections at each tracker. 2. Turn off Control Box and swap tracker showing error with another tracker on the SAS. (Tracker number is on the cable at the tracker connector). Turn the Control Box back on to reset SAS. If error number moved positions with the swapped tracker, then the tracker is the problem. Replace transducer if necessary. Refer to Transducer and Filter Cleaning and Replacement information in the "Maintenance and Parts" section of this manual. 3. If error continues to display for the same position even after trackers have been swapped, the tracker connector or SAS cable is the problem. 4. The defective tracker or SAS cable should be repaired, but SAS can still be operated without all four trackers operating. Remember balance point will change if a tracker is removed.

11-23



SAS Symptom 3 • "SAS will not lock on grade." Probable Cause • Tracker too close to reference or defective transducer in Tracker. 1. Verify that all cable connections are properly and securely connected. 2. Check that all trackers are sending out sound waves (transducer is making ticking sound) and grade lights are flashing. 3. If tracker is not working, check that transducer and foam filter are clean and free from damage. Replace transducer if necessary. Refer to transducer and filter cleaning and replacement information in the "Maintenance and Parts" section of this manual. 4. SAS beam and trackers may be too close to reference. Bottom of tracker must be minimum of 14 inches from reference. 5. Non-SAS compatible tracker attached to cable. Verify tracker has SAS compatible decal near S/N label.

11-24 Figure 11.02



SAS Symptom 4 • "SAS is not producing smooth surface." Probable Cause • Improper setup or Performance Menu Settings. 1. Verify that temperature bails are clean and securely attached. 2. Verify temperature bail symbol "T" is displayed on face of Tracker. If not clean or replace transducer. Refer to transducer and filter cleaning and replacement information in the "Maintenance and Parts" section of this manual. 3. Check that Trackers are between 14 and 24 inches from reference. 4. If there are gusty winds, lower SAS to get Trackers closer to reference. 5. Move the Tracker away from gusty heat source, such as engine fan exhaust. 6. Verify that the Trackers are not picking up erroneous signals from undesired reference. Example:

Head of material, end gate shoulder grade or material spillage from hopper.

7. Verify that the center of the SAS beam is between the midpoint and the forward 2/3 point of the tow arm. 8. Check to see if Averaging in Performance Menu is set too low. Factory setting is 50. 9. Check that Deadband in Performance Menu is not less than 3mm. System FiveTM Paver Operator's Manual

11-25


10. Check that Valve Offsets are set properly. 11. Check that the Gain setting in the Performance Menu is not set too high. Factory setting is 25.

SAS Symptom 5 • "Tracker picking up head of material." Probable Cause • Improper placement of Tracker 1. Move tracker forward of the material. Rotate Tracker to front of bracket or drill a hole in the beam far enough forward to move tracker away from material. 2. Check balance point. Balance point will shift when moving a tracker.
