: The XNX EC sensors employ the patented Reflex™ cell fault diagnosis routine, which checks for cell presence, cell dry‑out, and cell open or short circuit. Reflex™ is automatically initiated by the transmitter every eight hours, as well as on power‑up or sensor exchange.
| Symptom | Likely Cause | Fix | | :--- | :--- | :--- | | | Incompatible or unseated sensor | Power down, reseat sensor, ensure firmware matches sensor type. | | 4-20mA reads 0mA (open circuit) | Wiring polarity reversed on OUT1 | Swap the signal and ground wires on the PLC side. | | Reading drifts after warm-up | Moisture or debris on sensor | Remove sensor, dry with warm (not hot) air for 2 hours, reinstall. |
Unscrew the enclosure cover and remove the display module to access the terminal blocks.
