Environmental Monitoring: Monitor the temperature and humidity of the electrical box to ensure the cooling fan is working properly and to prevent equipment failure due to overheating.
Troubleshooting:
Grounding Fault: Check if the grounding wire connection is correct (size conforms to standards), avoid sharing power with other equipment, and ensure the grounding resistance is ≤0.5Ω.
Noise Interference: Use a ferrite filter to suppress high-frequency noise, and ensure that encoder data cables are routed separately from high-power cables to reduce electromagnetic interference.
Signal Anomalies: Measure input/output signals through the front panel test points to confirm they are within the normal range; check filter settings and output mode configuration.
Power Supply Issues: Measure the power module output voltage, check for loose power connectors, and investigate capacitor aging or terminal oxidation.
Compatibility Issues: Verify interface compatibility with the MOOG servo proportional valve, and check if signal conversion (e.g., MFB to EFB) is configured correctly.
Special Maintenance:
Redundancy Testing: Simulate a main module failure quarterly to verify the switching capability of the backup module (e.g., IN123-825-001), and record the switching time and data consistency.
Firmware Updates: Update firmware through official MOOG channels to fix known vulnerabilities and improve performance, ensuring compatibility and security.
