Operation and Maintenance Instructions
Install the module in a Tricon V9/V10 rack, ensuring secure seating and proper grounding
Use shielded coaxial cables for sensor connections; separate power and signal cables
Verify 24 V DC supply before power‑on; check LED indicators for normal operation
Configure sampling rates, filter parameters, and safety thresholds via Tricon engineering tools
Keep the module surface clean with a dry cloth; avoid moisture and corrosive substances
Periodically inspect connectors for oxidation or damage; tighten loose connections
Back up configuration data before replacement; use anti‑static measures during handling
Operate within specified temperature and humidity limits; avoid strong vibration
