Configuring the Material Indicator LED (PlasTell and CarpeTell)

You can assign specific LED colours on the machine to different plastic materials, making the scanning process faster and more intuitive. For example, the machine can be configured to show purple for PET and blue for PE. The colour assignments are fully customisable, so you can set them up in any way that works best for your workflow. For instance, you might choose to display green for materials you want to keep and red for those you wish to reject.
