Configuring A Blemish Sensor - Banner iVu Plus TG Series Instruction Manual

iVu Plus TG and Color Gen2 Image Sensors
• Set the Pass Count parameter.
The Minimum Pass Count is the minimum number of parts, labels, or features expected to fall within the
specified criteria. The Maximum Pass Count is the maximum number expected to fall within the specified
criteria. These settings are used to determine the pass or fail result of the inspection.
In the Demo, both the Minimum Pass Count and the Maximum Pass Count are set to 6, because the
inspection should find six letters. The letters turn green to indicate that the inspection passed.
6. Test a complete range of good and bad samples to make sure that the sensor accepts good parts and rejects bad
parts.
7. To complete the Area application setup, adjust the trigger setting as appropriate for the application.
Note: Remote Teach does not work with the Area sensor.

13.3 Configuring a Blemish Sensor

The Demo Mode application shows how the sensor, when configured as a Blemish sensor, can accept or reject parts based
on the range of edge pixels the sensor detects in the ROI.
1. Begin the setup with a good part.
2. Center the part to be tested in the Field of View (FOV).
3. Adjust the Region of Interest (ROI) so that it surrounds the feature of interest. In the Demo example, the feature of
interest includes the two irregular shapes below the Banner logo.
