Sauer-Danfoss MC200 Controller Module

The Sauer‑Danfoss MC200 Controller Module is a rugged microcontroller designed for dual‑axis valve or drive control in mobile equipment such as pavers and trenchers. Common failure points on this family include power‑supply over‑voltage, capacitor leakage on the board’s high‑current paths, and firmware corruption that can trigger watchdog resets or communication timeouts. For initial troubleshooting, verify 24 VDC input stability with a multimeter, inspect all surface‑mount capacitors for bulging or leakage, and review the module’s diagnostic LEDs or serial log for error codes indicating I/O faults or bus communication errors.[oss-gpt-20b]
