For rapid setup of gas detection with Xnx (HART/analog/modbus versions).
| 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 |
: Verify the transmitter markings match your area's hazardous classification.
Remove the protective cap from the sensor body, align the keyed pins of the plug-in cartridge, and push it firmly into place. Xnx Universal Transmitter Quick Start Guide
Wait for the reading to stabilize. Press to save the new zero baseline. Step 3: Span Calibration (Gas Verification)
Once wiring and sensor installation are complete, reattach the display module, screw the main enclosure cover tightly until fully seated, and tighten the cover locking screw. Switch on the 24V DC power source.
: The XNX is certified for worldwide use in hazardous environments. For explosion-proof integrity, the cover must be fully seated with at least 9 threads engaged , and conduit runs must have a seal fitting within 18 inches (45cm).

Enter the menu using your passcode and select > Zero Calibration .
The Honeywell XNX Universal Transmitter is a state-of-the-art gas detection platform designed to provide reliable, flexible monitoring for a wide range of hazardous gases. This quick start guide compiles the essential information needed to get your XNX unit up and running quickly and safely, covering everything from initial mounting to calibration and basic troubleshooting.
: Confirm that the transmitter labels match the hazardous area rating of the installation site. Check loop impedance | | F117 | Sensor
Enter the passcode (Default passcodes can be found in the manufacturer's user manual).
If you provide from the guide (quotes, steps, warnings, part numbers), I can help you:
: If fitted with the optional relay module, contacts are rated at 250 VAC 5A or 24 VDC 5A (resistive loads only). file.yizimg.com 4. Sensor Installation (Plug-in) To install or replace a sensor:
Correct wiring prevents signal interference and device damage. Terminal Block Connections
Always mount the transmitter with the sensor pointing vertically downward.
