The Webomatic board is an industrial controller used in vacuum‑packaging and thermoforming machines to manage process timing, sensor inputs, and motor drives. Common failure modes on similar PLC/drive boards include power supply degradation (brown‑out or ripple), capacitor leakage, solder joint fatigue on I/O headers, and firmware corruption due to improper updates. First‑check steps: verify the 24 V DC rail with a multimeter for correct voltage and low noise; inspect all connectors and surface‑mount components for visible damage or burn marks; read any diagnostic LEDs or error codes displayed on the panel and cross‑reference them against the service manual’s fault list.[oss-gpt-20b]
