If the 'Result' LED doesn't light up, the 'Result 2' switching output doesn't pulse, or the SICK Barcode Reader (CLV) outputs status ST = 2, it indicates an unsuccessful read. This could be due to several reasons: * No barcode was present in the reading field during the reading pulse. * The scan line may be positioned incorrectly. * The evaluation range of the scan line (CP values) might be improperly limited. * The barcode might be presented at an incorrect reading distance or be excessively tilted. * The reading angles could be too large or the barcode might be in the total reflection zone. To resolve this: * Synchronize reading with the object. * Ensure the barcode is centered on the scan line and check reading quality in the CLV Setup program using PERCENTAGE EVALUATIO...
