4.2 | Understanding COMMAND Status
The COMMAND Status area is shown at the bottom-right of the Apply View and provides a quick indication of the current operating state of the COMMAND ECU.
Operators should check COMMAND Status before attempting to engage Automatic Control. The status message indicates whether the system is ready to engage, currently engaged, waiting for an operator action, or unable to operate due to a warning, fault or incomplete setup condition.
Status Colours
The coloured frame around the COMMAND Status area provides a quick visual indication of the current system state:
- Green indicates that Automatic Control is
engagedcurrently or ready for normal operation.engaged.
- Yellow indicates that all requirements have been satisfied and the system is ready for Automatic Control engagement.
Red indicates that operator
actionaction, further setup or fault correction is required before Automatic Control can
engageoperate or continue operating.
Red indicates an error, invalid configuration or fault condition that must be corrected before operation.normally.
Typical Workflow
Before engaging Automatic Control:
- Confirm GNSS has achieved RTK fix.
- Confirm the correct project or design surface is loaded.
- Check COMMAND
Status.Status.
- Resolve any warnings or required actions.
- Engage Automatic Control only when COMMAND Status shows Ready to Engage.

Engaged - Calibrating
Automatic Control is engaged and the ECU is currently performing a calibration process.
Continue the calibration procedure as instructed.

Ready to Engage
All required conditions are satisfied and Automatic Control is ready to engage.
Press the engage button when ready to begin Automatic Control.
Engaged - Active
Automatic Control is engaged and may actively move the implement.
Continue operation while monitoring grade, machine behaviour and COMMAND Status.
Engaged - Low Speed
Automatic Control is engaged, but implement movement is disabled because machine speed is below the low-speed threshold.
Increase travel speed above the low-speed threshold if automatic implement movement is required.
Ready to Continue
Once COMMAND Status shows Ready to Engage, the system is ready for Automatic Control engagement.
