SORTEX A is an ATEX‑compliant optical sorting system used for grains, coffee, nuts and plastics, employing high‑speed cameras, lighting arrays and machine‑learning algorithms to detect color, shape and texture defects. Common failure points in this class include camera lens contamination or misalignment, LED illumination degradation, motor drive faults on the air‑jet ejector, and PLC/communication errors due to cable wear or firmware glitches. First‑check diagnostics should verify power supply voltage and current to the sorter’s mainframe, inspect the camera lenses and lighting modules for dust or damage, and review the latest error logs for any I/O or communication timeouts before proceeding with deeper mechanical or software troubleshooting.[oss-gpt-20b]
