# 4.2 | Understanding COMMAND Status

[![image.png](https://docs.t3rra.com/uploads/images/gallery/2026-06/scaled-1680-/GaEUkOtKQeU45dh0-image.png)](https://docs.t3rra.com/uploads/images/gallery/2026-06/GaEUkOtKQeU45dh0-image.png)

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 currently engaged.
- **Yellow** indicates that all requirements have been satisfied and the system is ready for Automatic Control engagement.
- **Red** indicates that operator action, further setup or fault correction is required before Automatic Control can operate normally.

### Typical Workflow

Before engaging Automatic Control:

1. Confirm GNSS has achieved RTK fix.
2. Confirm the correct project or design surface is loaded.
3. Check **COMMAND Status**.
4. Resolve any warnings or required actions.
5. Engage Automatic Control only when **COMMAND Status** shows **Ready to Engage**.

### <span style="color: rgb(0, 152, 8);">Green</span> Statuses - Automatic Control Engaged

Green statuses indicate that Automatic Control is currently engaged.

<table id="bkmrk-status-meaning-opera" style="width: 100%;"><thead><tr><th style="width: 19.5474%;">Status</th><th style="width: 42.0919%;">Meaning</th><th style="width: 38.2712%;">Operator Action</th></tr></thead><tbody><tr><td style="width: 19.5474%;">Engaged - Active</td><td style="width: 42.0919%;">Automatic Control is engaged and **COMMAND** may move the implement automatically.</td><td style="width: 38.2712%;">Continue operating normally.</td></tr><tr><td style="width: 19.5474%;">Engaged - Low Speed</td><td style="width: 42.0919%;">Automatic Control is engaged, but the machine is moving too slowly for **COMMAND** to move the implement.</td><td style="width: 38.2712%;">Increase machine speed above 0.2 km/h to allow automatic implement movement.</td></tr><tr><td style="width: 19.5474%;">Engaged - Calibrating</td><td style="width: 42.0919%;">**COMMAND** is controlling the implement as part of a calibration process.</td><td style="width: 38.2712%;">Continue the calibration procedure shown on screen.</td></tr></tbody></table>

### <span style="color: rgb(241, 196, 15);">Yellow</span> Statuses - Ready for Engagement

Yellow statuses indicate that the system is ready for Automatic Control, but Automatic Control is not currently engaged.

<table id="bkmrk-status-meaning-opera-1" style="width: 100.357%;"><thead><tr><th style="width: 20.6259%;">Status</th><th style="width: 40.6494%;">Meaning</th><th style="width: 38.7545%;">Operator Action</th></tr></thead><tbody><tr><td style="width: 20.6259%;">Ready to Engage</td><td style="width: 40.6494%;">The system is ready for Automatic Control.</td><td style="width: 38.7545%;">Press the engage button when ready to begin.</td></tr></tbody></table>

### <span style="color: rgb(224, 62, 45);">Red</span> Statuses - Operator Attention Required

Red statuses indicate that operator action, additional setup or fault correction is required before Automatic Control can operate.

Once **COMMAND Status** shows **Ready to Engage**, the system is ready for Automatic Control engagement.

Continue to **4.3 | Loading or Importing a Project** if a project has not yet been loaded, or continue to **4.5 | Engaging Automatic Control** if the project and zero reference are already prepared.
