6 Installation Installation Before working under header always: 1. Perform all combine and header manufacturer safety precautions for servicing header. 2. Insert stop to prevent movement of header. 3. Turn off combine and remove key from ignition. 4. Set combine parking brake. 5. Disconnect all drive shafts from the header. Required Equipment The combine must be equipped with the following OEM hydraulic components. Hydraulic accumulator & valve Automatic Drop rate valve See the Settings/Combine Settings portion of this manual to identify these components. If your combine does not have these, please contact your JD dealer. 1

7 Control Unit Complete the installation portion of the header manual before continuing. Installation 1. Connect the two mounting brackets together with two ¼" x ½" bolts and nuts. 2. Remove the two 5/16" head screws from under the outer lower edge of the armrest console. 3. Attach the enclosed armrest bracket to the armrest with the bolts removed in step Mount the control unit to the bracket using two ¼" x ½" bolts and nuts provided. Adjust angle as necessary. Main Harness To extend lifespan of electrical components, take 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. Open the access door just outside the cab door, and lay the coiled cable on the cab platform with the control unit connection plug Y811 on top. See Wiring for plug identification 2. Feed the control unit connection plug and cable under the cab immediately behind the JD main harness. 2

8 Installation 3. From the right side of the combine, pull the Y811 connection across under the cab and through the loop that holds up the JD main harness until the Y in the Headsight harness is just about to start under the left side of the cab as shown. Ziptie harness to existing cables at point indicated 4. Clean the area around the electrical access panel in the rear right corner of the cab. 5. Remove the 6 outer bolts holding the electrical access panel to the cab, and pull it away from cab. 6. Drill or notch a new access hole in area indicated. 7. Feed Y811 through the new access point and up into the cab through the rectangular cutout in the rear corner. Draw the harness fully into the cab and plug Y811 into controller. Make sure to have sufficient slack in cab 8. Reinstall the access panel and seal the hole around the cable with silicon. 9. Secure cab leg of harness outside cab and up to console with zipties. 10. Route the Y204 header connector forward over the frame rail and returns auger, and down around the feederhouse pivot point along with the JD feederhouse wiring. Follow existing wiring to front left of feeder Make sure to leave a slack for motion Make sure to leave adequate length to connect to header 11. Connect Y221 to OEM header connector on combine feederhouse. 12. Secure feeder leg of harness with zip ties, making sure all wiring is firmly held and not in danger of being rubbed or pinched. 3

9 Installation 13. Route Y821-Y824 & Y886 back along the left side of the combine. Secure along the shift cable and pipes to reach the JD Logic Module Disconnect the OEM plug from the Logic Module, and connect it to Y822 on the Headsight main harness Plug Y821 into the Logic Module 14. If the combine has lateral tilt, disconnect the original 4 pin flat Weather Pack plugs and connect Y823 & Y824 in between the original connectors. 15. Connect Y886 to the auto drop rate bypass solenoid. If your combine is not equipped with this valve, please see you JD dealer to install one See Settings/Combine settings for location of valve directly above main valve block 16. Route the short end of the main harness Y825 & Y826 up beside the main JD harness and over to the Header Clutch Solenoid connector. Disconnect the OEM JD 2 pin plug and connect Y825 & Y826 in between the original plugs 4

10 Installation Header Harness The Y204 header connector mates to OEM headers set up for JD 9x50 combines. Mate the header plug to either existing OEM header connector, or to the Headsight Header harness supplied with the Header Kit. For installation instructions, see the Header Sensor Installation Guide. 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.

11 Calibration Before working under header always: 1. Perform all combine and header manufacturer safety precautions for servicing header. 2. Insert stop to prevent movement of header. 3. Turn off combine and remove key from ignition. 4. Set combine parking brake. 5. Disconnect all drive shafts from the header. Calibration Sensor Calibration New Headsight sensors are pre-calibrated at the factory; you may skip this step. Recalibrate the sensors if you are unsatisfied with the operating range of the system, if any of the components of the system are replaced, or once annually. Some OEM sensors (such as JD green bar ) cannot be adjusted properly. If you cannot adjust the sensors as described below, use a voltmeter to set all sensor voltages as close as possible, and read the note under Operation, Adjusting Header Height. 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. Start the motor, raise the head, and install safety stop. Leave motor running Set the MODE switch to HGT 3. For flex heads, adjust the cutterbar sensors to V with the head flat on the ground. The Auto [Cal] light should just turn on at this low position. 4. For other sensors, move (any) one sensor arm back to the lowest position to which the ground could push the sensor during normal operation. This position should not be the mechanical limit and will vary slightly depending on header type and angle The Auto [Cal] light should just turn on when the sensor reaches this low position 6

12 Calibration If the Auto [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) Twist the sensor to a new position; stop when the Auto [Cal] light turns on More details may be found in the header manual HIGHER LOWER 5. Repeat step 3 or 4 for each sensor perform seasonally. 6. If needed, adjust the down stops for an equal hang angle for all sensors. 7. All sensors must be adjusted to an equal voltage/indicator position for the AHHC to perform properly. 7

13 Settings 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. For 20 series combines see owners manual for location of drop rate valve and accumulator series are shown. Automatic Drop Rate 1. Use the automatic drop rate valve adjustment knob on the main valve block. Turn in all the way then out ½ turn for initial guess. If the speed is to fast: Hunting will occur If the speed is to slow: The system will not be responsive enough 2. Common range is 8-12 seconds from header full up to full down in automatic mode. A B Settings A: Automatic Drop Rate Valve B: Manual Drop Rate Valve The maximum automatic drop rate is limited by the manual drop rate. Hydraulic Accumulator 1. Close the accumulator valve all the way. 2. Open the accumulator valve 1 full turn from the closed position. Opening the accumulator to far will give a sloppy response Not opening the accumulator far enough will give a jerky response 8

14 Operation Control Unit Layout 1 2 Operation Head Height knob: Adjusts Head Height; MODE must be set to HGT or HGT & TILT 2. Height Sensitivity knob: Adjusts Height Sensitivity, MODE must be set to HGT or HGT & TILT 3. Tilt Sensitivity knob: Adjusts Tilt Sensitivity; MODE must be set to HGT & TILT For a technical explanation of the Height, Sensitivity, and Tilt functions, see Advanced Information 4. Directional and Auto [Cal] Lights: The four directional lights indicate that solenoid output is activated. The Auto [Cal] light performs two functions During sensor calibration, it acts as a low point indicator to help set all sensors uniformly During operation, it will light when the auto height control system is activated 5. MODE switch: The MODE switch selects operating mode, allowing the user to turn off auto height control or operate height control without lateral tilt. The mode switch replaces an existing OEM AHHC on/off switch (if equipped) 9

15 Enabling Height Control When using the Headsight system, the MODE switch replaces the OEM DAM & Contour Master switches (if equipped) to turn ON/OFF the height control system. The OEM switches should be left OFF. Turn OFF the MODE switch any time you do not want the header to auto lower or raise. 1. Turn MODE switch on Headsight control unit to HGT or HGT & TILT. 2. Engage Header clutch. Operation 3. Press header lower button. The Auto [Cal] light on the control unit should be lit 4. To disable, press header raise. The Auto [Cal] Light on the control unit should be off 10

16 Adjusting Header Height 1. Turn the head height knob on the control unit with header control engaged. Clockwise = higher 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. Operation 3. To test if the height you have chosen is too low, engage the system, then press and release 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 Adjusting Height Sensitivity 1. Increase height sensitivity (turn CW) for more responsive performance. 2. Decrease height sensitivity (turn CCW) to reduce hunting. You MUST set your accumulator and drop rate valves before adjusting the sensitivity knob Adjusting Tilt Sensitivity 1. Increase tilt sensitivity (turn CW) for more responsive performance. 2. Decrease tilt sensitivity (turn CCW) to reduce hunting. 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 time is needed on wider heads See Advanced Info/Changing Tilt Orifices 11

17 Advanced Information Changing Tilt Orifices The purpose of changing the orifices is to decrease/increase the maximum speed that the Contour-Master can tilt. The factory configuration will be satisfactory for most conditions. However, wide headers may need to adjust the orifices. Only change orifices if the system cannot be set properly by using the sensitivity adjustment on the contour-master card. 1. The target tilt speed is 5 8 seconds from full right to full left for most machines. 2. Using 1/8" Allen wrench, remove original orifice from valve block in tilt cylinder supply lines. Keep orifice in secure location for later use if needed 3. If tilt speed is too fast: Install an orifice that is smaller than the original orifice removed 4. If tilt speed is too slow: Install an orifice that is larger than the original orifice removed, or remove orifice completely JD Orifice Availability.26" Z60904 (Original on 50/60 series).31" H (Original on 00/10 series).46" H Advanced Info 12

18 Theory of Operation A review of the following points will help the service technician to understand the complete system which will help diagnosing specific problems. Sensors Further information on sensors is available in the Header manual. 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) 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) Control Unit The control unit contains both the height control analysis circuitry, and the interface to work with the manual controls of the harvester. For a more detailed look at the controls, see Operation, Control Unit The control unit will not activate the outputs unless the Mode switch is on, the OEM All Harvest switch is on, and the manual header lower switch has been pressed Advanced Info Height Operation Head Height The control unit compares the sensor closest to the ground 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 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 Tilt The left and right sensor signals are compared and a tilt output is enabled as needed The tilt sensitivity knob sets the deadband Raise Point Lower Point Deadband 13

27 Troubleshooting Sensors and Harnesses To properly test the wiring and sensors on the header, follow the steps below in order. Use a Volt Meter as needed. The sensor connector pattern is as follows: Pin A is Ground (Black or Lt Blue) Pin B is Signal (White) Pin C is 5V (Green or Pink) A very common problem during install is to reverse the wires at the connector after removing the plug to route the cables. Make sure that the wires/voltages are as shown. If A & C are reversed, the voltages will swing backwards. The following requirements must be met before testing: Key on, combine engine running Header connected Error Code Problem Solution Bad Harness Wiring Disconnect Sensor Plug (Measure voltage on harness plug at sensor) Measure C to Frame Ground Voltage should be 5V Measure C to A Voltage should be 5V Jump C to B in harness plug Voltage should be 5V If not, check harness for continuity or short on 5V wire Check Combine 5V source If not check harness for continuity on ground wire Check combine sensor ground source If not check signal wire for broken harness or bad connection If you have a Headsight Sensor tester, use it to test the sensor. For all other: (For Insight systems, see Diagnostics/Display Sensor Voltages. For all others, use Combine Diagnostics*) All of the above are correct Verify sensor is connected to extension harness Sensor voltage should be V Harness & combine connections pass test. If sensor cannot be adjusted to achieve a voltage within the range, replace sensor. Diagnostics (For Insight systems, see Diagnostics/Display Sensor Voltages. For all others, use Combine Specific Diagnostics) 22
