7. Fully lower the combine feeder house (float module
should be fully separated from the header).

lowered.
8. Read voltage.
9. Raise header so cutterbar is 150 mm (6 in.) off the
ground.
10. Read voltage.
11. 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 Adjusting Voltage Limits: One-Sensor System, page 131 or
Adjusting Voltage Limits: Two-Sensor System, page 131.

Changes may have been made to the combine controls or display since this document was published. Refer to the
combine operator’s manual for updates.
The following system components are required in order for the auto header height control (AHHC) to work:
• Main module (PCB board) and header driver module (PCB board) mounted in card box in fuse panel
module (FP)
• Multi-function control handle operator inputs
• Operator inputs mounted in the control console module (CC) panel
