To make your header’s auto header height control (AHHC) system compatible with Case IH 7, 8 or 9 series combines, you
must set your combine’s header configuration options for the particular model of header, check the height sensor voltage
range, and calibrate the AHHC system to ensure that it is working correctly.
4.7.1 Checking Voltage Range from Combine Cab (Case 8010)
To ensure that the auto header height control (AHHC) system on your header works correctly with your Case IH 8010
combine, the output voltage from the header height control sensors must be verified.
NOTE:
Changes may have been made to the combine controls or the display since this document was published. Refer to the
combine operator’s manual for updated information.
