Installation Before working on combine or under header always: 1. Perform all combine and header manufacturer safety precautions for servicing header. 2. Insert stop to prevent movement of header. 3. Set combine parking brake. 4. Turn off combine and remove key from ignition. 5.
Control Unit 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 2.

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.

Module • Disconnect the OEM plug from the Logic Module, and connect it to Y 822 on the Headsight® main harness • Plug Y 821 into the Logic Module 14. If the combine has lateral tilt, disconnect the original 4 pin Weather Pack plugs and connect Y823 &...
The 31 pin header connector mates to OEM headers set up for JD 9x50 combines. A “single point” version is also available. Mate the header plug to either existing JD header connector, or to the Headsight® Header harness supplied with the Header Kit. For installation instructions, see the Header Installation Guide.
Set the MODE switch to HGT 3. For Headsight sensors, adjust them to 4.0V against the stops. Make sure the stops are adjusted correctly, so sensors all hang at the same angle first.. Or follow the steps below for “all sensors”.

• If the Auto [Cal] light does not just turn on at the lowest point: • Loosen the nuts or screws which hold the HIGHER 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 •...
Settings Harvester Settings Properly setting the machine is essential to having responsive header control. You should become very familiar with the steps in this section. Always perform the combine ground calibration before adjusting settings. Set each sensitivity setting by increasing till header bouncing occurs then decreasing till header becomes stable. •...

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.
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 –...
Low header height = low voltage (approximately 1 volt) • Sensor may not exceed 4 .. 5 V, or be less than 0 . 5 V 2. When using Headsight sensors, each sensor has 3 wires. Others similar. • black or Lt Blue = ground •...

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.
