Main Lift Trigger:
If the main lift switch is enabled as the trigger, the Headland Assist will be triggered when the
operator toggles the “main up” switch while in automatic mode. By toggling the “main down”
switch the boom will return to automatic mode. When in manual mode the main lift switch
will operate the normal main lift function.
Note: If the main lift switch is enabled as the trigger, the set point increment / decrement feature is
disabled for the main lift switch.
Remote Auto Trigger:
Enabling remote auto as the trigger will allow a separate switch to trigger the Headland Assist.
This switch must not be a momentary type switch. Remote auto is an input line normally
located in the wiring harness in the cab. Refer to Section 10.2 for the location of the remote
switch inputs.
When +12 VDC is applied to the remote auto line the system will change to automatic mode
from either manual mode or headland mode. When 0 VDC is applied to the line the system
will change to headland mode from automatic mode. If the system is put into automatic from
the display, then the voltage on the remote auto line will dictate what mode (auto or headland)
the system will start in.
Headland Assist Mode:
The Headland Assist feature can operate in two different modes; main lift or wings only.
If the main lift mode is selected, when the Headland Assist is triggered the wings will
temporarily be disabled and the main lift will raise to the predetermined Headland Assist height
to allow the operator to turn around at the end of the field. When triggered again, the entire
boom will return to automatic mode.
