💡 Operational Tips
- Wiring Guidelines:
- Use shielded twisted-pair cables for 4–20 mA signals to minimize electromagnetic interference (EMI).
- Avoid running signal wires parallel to high-voltage power lines.
- Configuration:
- Use Yokogawa’s FieldMate software or a HART communicator to set channel ranges, tags, and alarm thresholds.
- Enable HART communication for advanced diagnostics (e.g., sensor health monitoring).
- Maintenance:
- Regularly inspect terminal blocks for loose connections or corrosion.
- Replace the module if the LED indicator shows calibration data loss (red blinking).
