9. The SETTINGS page updates to display the voltage in
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. Adjust the voltage limits (refer to 4.4.2 Adjusting Voltage
Limits, page 137) if the sensor voltage is not within the low
and high limits or if the range between the low and high
limits is insufficient (refer to Table 4.1, page 134).
4.6.3 Calibrating Auto Header Height Control – Case IH 5130/6130/7130;
5140/6140/7140
The auto header height control (AHHC) sensor output must be calibrated for Case IH 5, 6, and 7 (Midrange) series
combines, or the AHHC feature will not work properly.
For best performance from 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. For instructions, refer to 3.7.4
Header Angle, page 78.
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 4.7.5 Calibrating Auto Header Height Control – Case IH 7010/8010;
7120/8120/9120; 7230/8230/9230; 7240/8240/9240 – Software Versions Above 28.00, page 159.
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 the most up-to-date information.
1. Ensure that the center-link is set to D.

2. Ensure that all header and adapter electrical and hydraulic
connections are complete.
3. Lower the combine feeder house all the way down.
4. Hold the DOWN button for 2 seconds.
5. Push the RAISE button and hold it until the feeder house
travels all the way up. It will stop 61 cm (2 ft.) above the
ground for 5 seconds, then it will resume rising. This is an
indication that the calibration procedure has been
successful.
