Calibrating Auto Header Height Control (Case Ih 5130/6130/7130, 5140/6140/7140) - MacDon FlexDraper FD1 Series Operator's Manual

8. From the PARAMETER menu, select LEFT
HEIGHT/TILT SENSOR (A).
9. The SETTINGS page updates to display the voltage in
the VALUE/STATUS field (A). Lower the feeder house
fully, and then raise it 305 mm (12 in.) off the ground to
view the full range of voltage readings.
10. If the sensor voltage is not within the low and high
limits, or if the range between the low and high limits is
insufficient, adjust the voltage limits. Refer to
Voltage Limits: One-Sensor System, page

Calibrating Auto Header Height Control (Case IH 5130/6130/7130, 5140/6140/7140)

For best performance of the auto header height control (AHHC), perform these procedures with center-link set to D.
When setup and calibration are complete, adjust center-link back to desired header angle. Refer to
Angle, page 81.
NOTE:
This procedure applies to combines with a software version below 28.00. For instructions on calibrating the AHHC
for combines with software version 28.00 or above, refer to
Combines with Version 28.00 or Higher Software), page
NOTE:
Changes may have been made to combine controls or display since this document was published. Refer to
combine operator's manual for updates.
NOTE:
If header float is set too light, it can prevent calibration of AHHC. You may need to set the float heavier for
calibration procedure so header doesn't separate from the float module.
1. Ensure center-link is set to D.
2. Ensure all header and float module electrical and hydraulic connections are made.
