4. Operating Principle
After power-on, the 8116071G001 board completes self-inspection, initialization and communication handshake with the host system and 8F cryopump. It continuously collects real-time data including secondary refrigeration temperature, cavity vacuum pressure and operating current, and performs closed-loop operation comparison with process preset thresholds.
The board automatically switches operating modes according to production demands: fast cooling and high-vacuum establishment during startup; dynamic refrigeration power adjustment to stabilize vacuum during mass production; low-power vacuum maintenance during standby; and regeneration pressure relief and reset during maintenance.
It monitors hardware and operating status in real time. Once abnormal conditions such as over-temperature, refrigeration failure, vacuum leakage and communication interruption are detected, it immediately activates protection logic, stops cooling output, uploads fault codes and triggers interlock alarm and shutdown to protect process stability and equipment safety. All operating and fault data are recorded for maintenance traceability and process analysis.
