Cera‑Mat II II is a high‑temperature ceramic processing unit typically used in dental laboratory furnaces or coating systems. Common failure modes for this class of equipment include power supply degradation (transformer/rectifier), motor drive overheating, and control board component burn‑outs due to voltage spikes. Initial checks should verify mains voltage and UPS status, inspect the main transformer and rectifier for signs of arcing or insulation breakdown, and review any error codes displayed on the panel or logged in the PLC. If faults persist, proceed with a continuity test of motor windings and a visual inspection of the control board for damaged capacitors or solder joints.[oss-gpt-20b]
