Avoidance Zones

WARNING – Entering an avoidance zone could cause personal injury or damage to the machine. Always be aware of nearby avoidance zones when operating a machine.

WARNING – You are responsible for observing safe operating practices. This product does not guarantee error-free avoidance zone guidance.

Avoidance zones indicate areas on a site that machines need to avoid. They appear as solid magenta shapes on the site plan and at the current machine elevation.

Avoidance zones display as horizontal boundaries that do not describe objects such as pipes or overhead wires.

Avoidance zones are available on machines with:

an applied project that has an avoidance file loaded into it
3D positioning sources only

Avoidance zone files are added to project files by the office or your technician.

Projects must be applied and include an avoidance zone file for the avoidance zones to display.

Avoidance zone icons

Applied projects that have avoidance zones (supplied by the office) can display the following icons:

You can continue working when any of these icons display. These icons are for information only.

Icon	Meaning	Action
	Project includes an avoidance file	Continue working
	Avoidance file cannot be loaded	Be aware that if you continue working, intended avoidance zones will not display. Notify your technician.
	Avoidance file has too many edges
	The avoidance file requires a 3D positioning source	Be aware that if you continue working, intended avoidance zones will not display. Notify your technician.
	Some machine measurements are not configured

The work screen

Applied projects that have avoidance zones (supplied by the office) can display the following border colors on the work screen:

Indicators	State	Machine proximity to zone
Blue border	Zone detected	The machine is approaching the avoidance zone but is still outside the warning perimeter.
Orange border Audible beep	Zone warning distance	The machine is within the warning perimeter of 8 m minimum, configurable in the Web Interface.
Magenta border Continuous audible beep	Zone breached	The machine is in the avoidance zone.

Indicators

State

Machine proximity to zone

Blue border

Zone detected

The machine is approaching the avoidance zone but is still outside the warning perimeter.

Orange border

Audible beep

Zone warning distance

The machine is within the warning perimeter of 8 m minimum, configurable in the Web Interface.

Magenta border

Continuous audible beep

Zone breached

The machine is in the avoidance zone.

When a machine breaches an avoidance zone, full guidance continues.

WARNING – When an attachment is fully curled in, the stick may extend into an avoidance zone before the breach is reported on screen and audibly.

Machine boundary

The machine boundary is the magenta outline around the machine.

To show or hide the machine boundary outline, use the Machine Boundary toggle on the Overlays screen.

Avoidance zone limit

Each avoidance zone can have up to 800 segments (or sides) per polygon.

The system supports multiple avoidance zone polygons. For best performance:

Try to keep individual avoidance zones below 500 segments.
Break up a large or thin polygon into multiple polygons with similar dimensions.

If an avoidance zone fails validation, use the ProjectDiagnostics.txt file to troubleshoot it. See the Project and Design Files User Guide for details.

Troubleshooting

The table below lists an error message that may appear when working with avoidance zones.

Error Message	Possible cause(s)	Action
Avoidance Zone Proximity and Guidance Lost	Machine orientation is unknown.	Identify the avoidance zone on the site and move or rotate the machine away from the avoidance zone.
