Novatec GDM-3000 MCD-3000 control board

Novatec GDM‑3000 MCD‑3000 is a microprocessor‑controlled dryer interface board used in plastic injection molding lines. Common failure modes on this class of controllers include burnt or tripped power supply fuses, degraded I/O relays, and firmware corruption that manifests as erratic cycle times or “offline” status. Start by verifying the 24 V DC input voltage and inspecting the main power transformer for overheating; then check all connector pins for continuity and look for visible burn marks on the board’s surface mount components. Finally, review any stored error codes in the device log and perform a quick firmware checksum to confirm integrity.[oss-gpt-20b] Post Comment
