fastest reaction time. A reaction time of 0 turns the main lift control off. A slower main lift
reaction time can be beneficial in uneven crops to prevent the boom from making unnecessary
movements. A reaction time of zero can be beneficial in tall crops where the crop is being
pushed over by the sprayer chassis to prevent the center section from moving too low.

Slant Reaction:
The slant reaction time is how long the slant waits between adjustments. This setting is only
visible when the slant control is enabled. The slant reaction time can be adjusted from 0 to 5.
A setting of 1 is slow and a setting of 5 is the fastest reaction time. A reaction time of 0 turns
the slant control off. It is best to set the slant reaction to a low setting in flat fields as the slant
is generally not required in flat fields. It is best to set the slant reaction to a higher setting in
uneven terrain or on side hills. Setting the slant reaction too high will cause the boom to
oscillate and decrease the performance of the system.
Learned/Expected Crop Height:
The learned crop height setting is used when spraying in Hybrid Mode. When Learned Crop
Height is checked, the UC5 system will attempt to learn the average crop height using all crop
readings that are measured by the ultrasonic sensors. If Learned Crop Height is unchecked, the
operator can enter an expected crop height. The expected crop height is then used to try and
achieve a more accurate average crop height reading by excluding ultrasonic sensor readings
that are outside the acceptable distance from the expected crop height. In most situations
leaving the Learned Crop Height setting checked will provide adequate performance.
6.4 Sprayer Switches
When a sprayer switch is pressed, an arrow will be displayed on the screen showing which
function is being activated (Figure 5). For example, if the left up switch is pressed then an
arrow will be shown above the left boom pointing up. Some sprayer types do not support this
functionality.
Tilt Switches:
While in Automatic Mode if either left or right tilt boom switches are pressed, the
corresponding boom section will go into Manual Mode, but other boom sections will remain in
Automatic Mode. To return all boom sections to Automatic Mode, press the “AUTO” button.
If the Double Tap Wings function is enabled, the tilt down switches can be used to resume
Automatic Mode provided that at least one boom section is already in Automatic Mode.
