System Application This Headsight™ height control system is designed for New Holland TR

series combines. It updates these machines from a single position “switch” height control to full range adjustable height control. This allows these combines to work with any of the newer OEM headers (74C, 98C) as well as Headsight™ sensors.

Due to the design of the NH-TR combine, there is no “safety” circuit to shut off the HHC when the head is not running. Make sure to turn OFF the MODE switch any time you do not want the header to auto lower or raise. Disconnect the 1p “Safety” plugs whenever you are working on the header.

1. Installation

If you are installing a Headsight™ Sensor system on a header, complete the installation portion of the header manual before continuing.

1.1. Control Unit

1. On earlier combines, mount the control unit and bracket to the bottom of the gauge console in the approximate location shown with the two self tapping screws provided.

2. On late model TR’s a suggested mounting is just to the right of the control corner post, either on the control console or on the ceiling. Use the extra “standup” bracket included if desired.

3. Make sure to leave clearance for the harness to plug into the rear of the control unit.

1.2. Main Harness

CABLE ROUTING NOTE: Cable routing properly takes time, but is essential to long life of electrical controls. Take the time to fully understand

the routing requirements, and carefully route and tie all cables in safe locations away from heat, wear, or pinch points.

1. Connect the 16 pin round connector to the back of the control unit, and route the harness back under the header indicator lights assembly. Making sure the fuse holder and power connection stays inside the cab, route the rest of the harness around the rear of the meter console and out the side cab window. Close the window on the cable to hold it at the correct spot.

2. Remove the hydraulic valve body access panel. Route the cable down to under the cab, using the cutout area as shown to get the cable past the hydraulic tank. Pull the cable all the way down through until it lies neatly between the cab wall and the combine body.

3. Route the Header section of the main harness under the cab and down with the OEM wiring/hoses to the right front of the feederhouse. Make sure to leave “slack” for the feederhouse motion.

4. Route the 31 pin header harness connection over the front of the feederhouse to the left side, securing it to the OEM hoses. Loosen the hose shield and put the cable inside, if desired.

5. If your head already has an OEM hazard lights connection to the combine, just tie the lights adapter plug back to the main harness. Use the lights adapter plug when connecting newer NH headers (74C, etc), or when installing a non-OEM header.

Older NH combines may use a flat

connector for lights instead of the round connector. Contact Headsight® or have your dealer make an adapter.

6. Route the solenoid connection section over to the Hydraulic valve block.

6.1. Disconnect the OEM PUR/Or wire from the Header Raise coil and connect it to the BRN wire using the bolt provided. Insulate with tape.

6.2. Attach the YEL wire to the Raise coil.

6.3. Disconnect the OEM PUR/Lt.Bl wire from the Header Lower coil and connect it to the Dk.GRN wire using the bolt provided. Insulate with tape.

6.4. Attach the Lt. GRN wire to the Lower coil.

6.5. Attach the ORG wire to the Tilt Left (CCW) coil along with the WHT/Yel wire.

6.6. Attach the Dk.BLU wire to the Tilt Right (CW) with the WHT/Bk wire.

7. Connect 1 pin plugs with the Red (power) and Purple (safety) wires together. If desired, a switch may be inserted into this connection to shut off the HHC (such as a seat switch). Opening the circuit disables HHC.

5

8. Open the fuse panel access door right in front of the gearshift. Route the power connection into the area thru the slot.

9. On earlier model combines (TR86, 97, etc.) plug the Red wire (12V) into the loose 4 pin molded plug that is inside the fuse area as shown. It must be plugged into the terminal shown.

Connect the Red wire (power) to the terminal with the Red wire

Connect the Grey wire (master) to the terminal with the Purple/Lt Green wire

10. Solidly connect the black wire (GND) to the bolt shown at rear of fuse area, or any other good clean chassis ground point.

11. On later model combines (TR89, 99), the plug shown above is used for the reel controls (see picture below). IN this case, it is suggested that the wires be connected by stripping the OEM wire to the plug connector, and crimping the Headsight wires onto them (remove terminals). Two parallel splice crimp rings are included. Spread the rings enough to slip over the OEM wires and then insert the Headsight wire and crimp. Use electrical tape to insulate the crimps.

Connect the Red wire to the Red wire in the plug Connect the Grey wire to the Purple/Lt Green wire in the plug

12. Carefully check and tie up all cables so they are neat and out of the way, will not catch on any moving parts, and have adequate slack to allow header movement.

The two plugs shown must remain together. The HHC system may be tested by disconnecting these plugs, and inserting the Headsigth wires as noted above (as shown during system testing by Headsight®.) Do not install kit with red wire as shown.

1.3. Header Harness

1. For 74C, 98C type headers with preexisting sensors

For 98C type heads, no adapter harness is necessary, attach the header connector directly.

For 74C headers, no adapter harness is necessary. However the right sensor must be reversed electrically. Please see the instructions under 3: CNH Flex headers for directions

2. For headers without existing sensors

Mount the header interface harness 31pin connector on the left rear of the header near the feederhouse using the included bracket. Connect the Headsight ™ combine header connector.

o For sensor installation instructions, see the appropriate Header Sensor Installation Guide.

3. For other headers with existing sensors

See note below.

Adapter harnesses are available to connect OEM Headers with preexisting OEM sensors to the Headsight™ height control. Contact Headsight™ for the correct part number for your specific application.

2. CNH Flex headers

2.1. NH 74C sensor modification The Headsight® system requires that both header sensors be at nearly equal voltage throughout the stroke of the sensor. The OEM right hand sensor must be reversed electrically for the Headsight® system to work properly. An electronic reverser is included with the kit for this purpose.

1. Reverser Installation

1.1. Identify the right height sensor harness connector on your header

using the pictures below. (Right end as viewed from the seat in the cab.) It is located at the right upper rear corner of the header, and on some heads it may be tucked into the main frame tube.

1.2. Insert the Headsight® electronic reverser included with the kit into the connector.

2.2. CIH 2020 sensor modification The Headsight® system requires that both header sensors be at nearly equal voltage throughout the stroke of the sensor. The OEM right hand sensor must be reversed electrically for the Headsight® system to work properly.

1. On the right sensor ONLY, reverse the red and black wires (A & C) in the sensor connector using a Weather Pack pin pushing tool.

2. Follow the instructions given for 74C headers to properly adjust and maintain the header.

9

2.3. 74C adjustments In order for the height control to work properly, the pad sensing cross rods and sensor linkages MUST turn freely with no binding. The cross rod on 74C type headers has proven troublesome in field use. Please see the pictures and descriptions below to keep your head working properly.

2.3.1. Initial adjustment: all 74C heads On each end, make sure that the short end section of the rod is properly aligned with the main cross rod by adjusting these two bolts. This rod is not in alignment.

On each end, loosen the two bolts shown and align the end carrier bearing so the cross rod is not binding, and pivots freely. However, the rod must still clear the skid pad arm when the head is lowered fully.

For 2007 and up headers, make sure the linkage is in the two holes shown on each end.

Adjust the linkage to make sure the arm does not hit the frame when the header is all the way down on the ground.

10

2.3.2. Maintenance: all 74C heads

It cannot be stressed strongly enough that you MUST keep the header sensing system lubricated and cleaned of trash buildup.

Note how trash buildup on the arm under the rod has bent the end section of the sensing rod. KEEP THIS AREA CLEANED OFF!!!

Keep the cross rod bearings lubricated.

The bent cross rod is causing pressure and binding here. This sensor will not “return”, but will stick in the “down” position.

The Return spring on 2007—up headers is not strong enough to return the sensor if the cross rod is binding.

Also, the sensor arm can “seize” on the pivot block due to dirt build up. Keep this area cleaned and lubricated!

11

2.4. 74C sensor calibration The goal of calibration is to make both sensors “see” the same ground height, so the head cuts level. Thus, both sensors should have the same output voltage (+/- 0.2V) when the header is sitting level. The easiest place to adjust this is when the head is sitting flat on the ground on a level surface.

2.4.1. Measuring voltage On each end, sensor voltage should be measured on the yellow wire HERE, after the reverser. Use a pin or wire-piercing probe, and measure to the chassis as ground. If you do not wish to use a voltmeter, see 3.4.4. Final adjustment

The voltage should be 1.2-1.5V with the header fully lowered on the ground, but if these voltages cannot be reached, it is more important that the two sensors be the same voltage.

2.4.2. Pre-2007 headers Very little adjustment is possible. If the sensors are out of adjustment, the holes for the sensor bolts must be “egged out” to rotate the sensor on the bracket.

2.4.3. 2007—up headers Adjust the rod to achieve the right voltage, making sure the sensor arm still clears the frame as noted above. If necessary, the sensor bolts can be loosened and the sensor rotated slightly to reach the required voltage.

2.4.4. Final adjustment

12

If the header still does not cut level after the above adjustments, the sensors can be “tweaked” to achieve level at the selected cutting height. Simply adjust either sensor until the header sits level at the selected cutting height.

3. Calibration

Before working under the header always:

1. Perform all combine and header manufacturer safety precautions for servicing header.

2. Disconnect “safety” 1p plugs

3. Lower stop to prevent movement of header.

4. Set combine parking brake.

5. Disconnect all drive shafts from the header.

3.1. Sensor Calibration (exc. 74C)

You will not need to calibrate the sensors for new installations because they are pre-calibrated at the factory. You may recalibrate the sensors if you are unsatisfied with the operating range of the system. You should perform calibration if any of the components of the system are used, or once annually.

This step will require 2 people. Its purpose is to “level” the sensors so the control system sees the same ground height for each.

1. Attach all harness and sensor wiring.

2. Power the header control system.

o Start the motor, raise the head and install safety stop. Leave motor running.

o Set the MODE switch to OFF.

o Turn the OEM Header Height switch OFF.

13

3. Move (any) one sensor arm back to the lowest position to which the ground could push the sensor during normal operation.

o This position should not be to the mechanical limit and will vary slightly depending on header type and “angle”.

o The ACTIVE [CAL] light should just turn on at this low position.

You will not be able to adjust OEM sensors (such as JD) properly. If you cannot adjust the sensors as described below, use a voltmeter to set all sensor voltages equal (within 0.2V), and read the note under 5.3 “Adjusting header height”.

o If the ACTIVE [CAL] light does not just turn on at the lowest point:

Loosen the nuts or screws which hold the sensor (the hall effect sensor or potentiometer – NOT the entire sensor assembly) and twist the sensor to a new position which does just turn on the CAL light. More details may be found in the header manual.

4. Repeat step 3 for each sensor – perform seasonally.

5. If needed, adjust the down stops for an equal hang angle for all sensors.

Lower Higher

Loosen 2 nuts and rotate sensor as shown

4. Settings

4.1. Combine Settings

Properly setting the combine is essential to having responsive header control. You should become very familiar with the steps in this section.

Set the automatic drop rate as high as you like without causing head “hunting”. If the head “hunts”, decrease the automatic drop rate.

See owner’s manual for location of drop rate valve and accumulator.

4.1.1. Header drop and raise rates

1. Adjust the lower rate adjustment on the main valve stack to approx. 8-10 seconds from header full up to full down. To adjust, loosen lock nut and turn bolt in (slower) or out (faster).

o If the speed is to fast – hunting will occur.

o If the speed is to slow – the system will not be responsive enough.

2. Adjust the raise rate valve adjustment on the main valve stack to approx. 5-6 seconds from header full down to full up.

3. Fine tune lower rate as needed, do not set raise rate any slower.

4.1.2. Hydraulic accumulator

If you do not have any accumulator, please contact either your local dealer or Headsight™ to install one. It will result in much improved operation and less stress to both you and the machine in all situations, manual or auto.

1. Make sure that your accumulator is properly charged (see your NH owners’ manual). To properly set accumulator, follow the instructions below.

o Close the accumulator valve all the way

o Open the accumulator valve 1 full turn (from closed position). Fine tune as necessary during field operation to remove the “jolt” without making head response “mushy”

Opening the accumulator too far will give a “mushy” response. If the header constantly overshoots, even after drop and raise rates are slowed down, close the accumulator valve or recharge it.

Not opening the accumulator far enough will give a jerky response.

5. Operation

5.1. Control Unit Layout

5.2. Enabling Height Control

1. Make Sure the “Safety” 1p connection is together.

2. Turn MODE switch to HGT or HGT & TILT.

Due to the design of the NH-TR combine, there is no “safety” circuit to shut off the HHC when the head is not running. Make sure to turn OFF the MODE switch any time you do not want the header to auto lower or raise. Disconnect the 1p “Safety” plugs whenever you are working on the header.

3. Press header lower button. The AUTO light should now be lit.

4. To disable, press header raise. The Auto Light should be off.

5.3. Adjusting Header Height

1. Turn the head height knob on the control unit with header control engaged.

o Clockwise = higher

o Counter-clockwise = lower

2. Find and mark the minimum acceptable height as noted below, do not operate below this point.

Because the Headsight™ control unit is designed to work with many OEM sensors, it may be possible for the operator to choose a height that is “too low” for operation – meaning that the sensors would never send a raise signal. To test if the height you have chosen is too low, engage the system, then tap the lower button on the hydro handle. If the header ‘bounces back’ up to its original position, the chosen height is fine. If the header stays in the new position, the height chosen is too low – do not operate header control at or below this height.

5.4. Adjusting Height Sensitivity

1. Increase height sensitivity (turn CW) for more responsive performance.

2. Decrease height sensitivity (turn CCW) to reduce hunting.

o You MUST set your accumulator and drop rate before adjusting the sensitivity knob.

5.5. Adjusting Tilt Sensitivity

1. Increase tilt sensitivity (turn CW) for more responsive performance.

2. Decrease tilt sensitivity (turn CCW) to reduce hunting.

o You may need to adjust the hydraulic flow rate before adjusting the sensitivity knob. The head should take at least 5 seconds to tilt fully from one side to the other, more for wider heads.

18

A. Theory of Operation A review of the following points will help the service technician to understand the complete system which will help when diagnosing specific problems.

1. Control Unit: Front Panel Controls

The control unit contains both the height control analysis circuitry, and the interface to work with the manual controls of the harvester.

o The MODE switch allows the user to operate height control without lateral tilt.

o The control unit will not activate the outputs unless the “safety” is connected, and the manual header lower switch has been pressed.

o The ACTIVE [CAL] light performs two functions. During sensor calibration, it acts as a “low point” indicator to help set all sensors at the same point. During operation, it will light when the auto height control system is activated.

2. Sensors

Further information on sensors is available in the Header manual.

o Each sensor returns a variable voltage to the control unit depending on its height.

high height = high voltage (approximately 4 volts)

low height = low voltage (approximately 1 volt)

o Each sensor has 3 wires (colors of OEM sensor wires vary)

red = 5V power

black = ground

white = signal returned to the control unit (varies between approximately 1.0 and 4.0 volts)

19

3. Height Operation

o Head Height

The control unit compares the lowest (most smashed) sensor to the desired height chosen with the height knob.

If any sensor has a lower voltage (is nearer the ground) than the height setpoint voltage – the box energizes the raise output.

This means that any one sensor can raise the head.

If all sensors have a higher voltage (are farther from the ground) than the height setpoint voltage plus the deadband chosen by the sensitivity knob – the control unit energizes the lower output.

This means that all sensors must agree to lower the head.

o Sensitivity

The sensitivity knobs on the control unit adjust the size of the deadband.

The deadband is a small area where the system will neither raise nor lower (or tilt).

This helps prevent the header from hunting.

o Tilt

The left and right sensor signals are compared and a tilt output is enabled as needed. The tilt sensitivity knob sets the deadband.
