Setting The Sensitivity Of The Auto Header Height Control (Claas 500 Series) - MacDon FlexDraper FD1 Series Operator's Manual

Setting the Sensitivity of the Auto Header Height Control (CLAAS 500 Series)

The sensitivity adjustment controls the distance the cutterbar must travel up or down before the auto header height
control (AHHC) reacts and raises or lowers the feeder house. When the sensitivity is set to maximum, only small
changes in ground height are needed to cause the feeder house to raise or lower. When the sensitivity is set to
minimum, large changes in the ground height are needed to cause the feeder house to raise or lower.
NOTE:
The upper and lower limits of the header must be programmed into the CEBIS before adjusting the sensitivity of the
AHHC system. The setting can be adjusted from 0–100%. When sensitivity is adjusted to 0%, the signals from the
sensing bands have no effect on the automatic cutting height adjustment. When sensitivity is adjusted to 100%, the
signals from the sensing bands have maximum effect on the automatic cutting height adjustment. The
recommended starting point is 50%.
NOTE:
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.
