Use the Grading tab to tune how pallet defects affect the pallet score.

Grading does not choose a lane by itself. It controls defect weights. Routing can then use values such as Pallet Score or Grade when you want scoring to influence lane decisions.

Open the Grading tab

1. Open a pallet vision data source.
2. Click the Grading tab.

The Grading tab is available for pallet devices that support pallet grading.

How grading works

Each supported defect has a weight from 0 to 10.

• Use 0 when a defect should not affect the pallet score.
• Use a low value for minor defects.
• Use a higher value for defects that should strongly affect the score.

The grading setup is saved as a defect-weight list. When pallet inspection results are processed, those weights are used to calculate the pallet score that can be reviewed or used by routing rules.

Review the defect weights

The table shows one row per defect.

The supported defects are:

• Mold
• Major Crack
• Broken
• Minor Crack
• Missing Board
• Missing Stringer
• Missing Block
• Twisted Block
• Damaged Block

Each row has a slider and a number field. Both controls update the same weight.

Change a weight

1. Find the defect you want to tune.
2. Drag the slider or enter a number in the weight field.
3. Pause for the automatic save to finish.
4. Review the confirmation message.

Changes are saved automatically after a short delay. You do not need to click a separate save button.

Weight range

Weights must be between 0 and 10.

If you type a value below 0 or above 10, the field is corrected back into the allowed range when you leave the field.

Defaults

If a pallet device does not have saved grading settings yet, Zira starts from the built-in defect weights:

Use these as a starting point, then adjust the weights to match the site policy.

Use grading with routing

Use routing rules when grading should affect where pallets go.

1. Tune the defect weights in Grading.
2. Open the Routing tab.
3. Add a rule that checks Pallet Score or Grade.
4. Choose the lane and disposition for pallets that match the score rule.

For example, a site may route pallets with a high pallet score to repair-lane or scrap-lane, while pallets below the threshold continue to the default good lane.

Tips

• Change one or two weights at a time so the effect is easier to understand.
• Use the number field when you need an exact weight.
• Use the slider when you want to compare several weights quickly.
• Give severe structural defects higher weights than cosmetic defects.
• Wait for the save confirmation before making a large round of changes.
