: Transmitters can be daisy-chained; maximum distances depend on cable gauge (e.g., 18 AWG to 12 AWG). Relay Ratings
: Connect positive to Terminal 1 and negative to Terminal 2.
After about 30–60 seconds, the unit will enter normal monitoring mode, displaying the current gas concentration. 4. Navigation and Magnetic Wand

The XNX is designed to work with various sensor technologies, including: For toxic gases and Oxygen. Catalytic Bead: For flammable gases (LEL). Infrared (IR): For combustible gases and CO2. Share public link The screen will prompt for
If the XNX is not functioning correctly, check for these common issues:
Connect to +24V DC nominal power source (acceptable range: 16-32V DC).
4–24mA (Sink/Source), Optional RS-485 Modbus, Foundation Fieldbus Relay Outputs (Optional): 3 x SPDT Form C (5A at 250V AC) Optional RS-485 Modbus
Turn on the power supply. The display will show the firmware version and then the "Warm-up" screen.
The XNX can be mounted in several configurations using the integrated mounting shoes:
Disconnect the gas supply. The XNX will temporarily hold the 4-20mA output in a "Maintenance" state to prevent false alarms at your controller while the residual gas clears from the sensor. 7. Basic Troubleshooting and Fault Codes
