5 - Operation
The sprayer's boom lift control (main up or main down) switches provide a target height adjustment feature. If you press
and hold either the main up or the main down switches for more than two seconds, the AutoHeight panel will switch ALL
booms (left, right, main, and roll) to MANUAL mode. This feature provides a convenient method of switching to MANUAL
mode when folding the sprayer for transport.
Adjusting the Target Height (Setpoint)
Adjust the target height setting with the "+/-" switch while in AUTO mode. The smallest target height setting allowed is
called the minimum height override. The default minimum height settings are programmed before shipped from the
factory.
÷
NOTE! The minimum height settings are adjustable. If you wish to adjust them, please contact HARDI for details.
You can also adjust your boom lift target height by pressing the sprayer's boom lift control switches. Each press of the up
switch will increase the target height by one unit. Each press of the down switch will decrease the target height by one unit.
Viewing the Actual Boom Height
When in manual mode the run screen shows the average of all the sensor heights. In automatic mode the number shown
on the run screen is the target height. Sensor height menus can be viewed in both automatic and manual mode.
• Toggle "SENSOR DISPLAY" to view the actual sensor heights. The left, right, and main (centre) sensor heights are each
displayed on a separate screen. If there are 2 sensors on each wing, both sensor heights will be displayed on the same
screen.
• To lock the currently viewed sensor heights on the screen indefinitely, toggle the "+" switch once.
μ
ATTENTION! The sensor heights are shown in either centimeters or inches depending on the sprayer type. The height
displayed is measured from the spray nozzles to the soil (soil mode) or crop canopy (crop mode).
Sprayer switches
When a sprayer switch is pressed, an arrow will be displayed on the screen showing which function is being activated. For
example, if the left up switch is pressed, an arrow will be shown on the left side pointing up.
Tilt Switches
While in automatic mode, if either left or right tilt switches are pressed, the corresponding boom section will go into manual
mode. The corresponding "A" on the display will change to an "M" to indicate that boom is in manual mode. This is useful
when spraying near ditches or fences where you would like to manually control one of the booms while leaving the other
boom in automatic mode. To return all boom sections to automatic mode, toggle the "AUTO (YES)" switch. If the system is
operating with only one boom in automatic mode, you will occasionally hear an audible chirp to remind you that one of the
booms is in manual mode.
Boom Lift Switch
While in automatic mode, if the boom lift up or down switch is momentarily pressed, the target height is incrementally
adjusted up or down.
If HeadlandAssist is enabled with the trigger as the boom lift switch, the boom lift switch will be used to control
HeadlandAssist instead of the target height. The boom lift up switch will activate HeadlandAssist. By toggling the boom lift
down, the system will return to automatic mode. See "HeadlandAssist" on page 42 for more information on HeadlandAssist.
Pressing and holding the boom lift switch will always put the system into manual mode.
Changing the Sensitivity of the System
The Sensitivity (Sensi) setting ("Sensitivity (Sensi) Setting" on page 14) can be adjusted in both MANUAL and AUTO
modes. Toggle the "SETUP (NO)" switch to view the current Sensi setting. While viewing this menu, toggle the "+/-"
switch to adjust the value.
• Decreasing number will reduce the system sensitivity and dampen the system.
• Increasing the number will speed up the response and improve the boom stability.
