The Xnx Universal Transmitter supports 24 VDC (nominal, 18-30 VDC) and can be configured for 3-wire (power, ground, signal) or 2-wire (loop-powered) operation. This guide covers the common 3-wire 4-20mA setup. Xnx Universal Transmitter Quick Start Guide
Install certified conduit seals or cable glands within 18 inches of the enclosure to maintain explosion-proof integrity.
| Fault Code | Description | Recommended Action | |------------|-------------|--------------------| | F112 | 24 VDC supply bad | Check wiring of 24V power supply to transmitter and sensor supply operation | | F113 | Sensor internal 5V power supply defect (Excel) | Remove and return to Honeywell for repair | | F116 | Optima lamp failure / Excel loop failure | Check that supply voltage is stable. Check wiring between Optima/Excel and the transmitter. Check loop impedance | | F117 | Sensor loop failure (losing/has lost mA signal) | Check switches S3 and S4 are set correctly. Power down before changing switch settings. Perform a Soft Reset after resolving the issue | | F118 | Excel real‑time clock issue | Reset date/time in Excel, recycle Excel power. If not retained, return to Honeywell for repair | | W002 / F103 | Temperature error | Check for heat sources. Install sun shield or relocate transmitter. Verify temperature reading in Info → Transmitter Status menu | | W022 | mV sensor calibration needed | Generated after accepting a new mV sensor or changing gas selection. Perform a span calibration | | W015 | Excel internal software error | Remove and return to Honeywell for repair |
Attach the optional pipe mounting kit for horizontal or vertical pipes (2-inch diameter). The analog signal can be configured as Source,
The standard XNX terminal block is split into distinct functional zones:
Its "universal" nature means it uses a common interface for all sensor types, simplifying maintenance and training across your facility. 2. Mounting and Installation
Turn off the gas cylinder regulator and remove the calibration cup. | Fault Code | Description | Recommended Action
Correct wiring prevents signal interference and device damage. Terminal Block Connections
✔ Keep a copy in your tool bag for wiring pinouts and LED codes. ✔ For first-time users, read the full manual before connecting power — but for repeat installs, this guide is perfect.
