Figure 4.155: Set the Cutting Height Manually
Adjusting the Sensitivity of the Auto Header Height (Lexion 500 Series)
Setting the sensitivity of the auto header height control (AHHC) system influences the reaction speed of the
AHHC on the header.
NOTE:
CEBIS must learn the upper limits and the lower limits of the header before you adjust the sensitivity of the
AHHC system. The setting can be adjusted from 0 percent to 100 percent. When sensitivity is adjusted
to 0 percent, the signals from the sensing bands have no effect. When set to 100 percent, sensing bands
have maximum effect on the automatic cutting height adjustment. 50% is a recommended starting point.
