Sauer Danfoss MC300 AT302696 Controller

The Sauer Danfoss MC300 AT302696 is a rugged multi‑loop controller designed for mobile off‑highway hydraulic systems, capable of operating as a stand‑alone unit or networked via high‑speed CAN. Common failures include loss of communication with slave units, output driver faults on the 12/24 V rail, and water ingress damage to the PCB or connectors. First‑check diagnostics should verify the main power supply voltage and continuity to the controller’s input pins; inspect all CAN and I/O connectors for corrosion or loose contacts; and review any stored fault codes or diagnostic LEDs for indications of driver or communication errors.[oss-gpt-20b]
