The XNX features an onboard diagnostic system that outputs distinct error codes on the LCD screen to assist in rapid troubleshooting. Error Code Description Corrective Action Sensor Fault Sensor cartridge missing or disconnected. Power down, verify sensor seating, and restart. F112 Over-Range Gas concentration exceeded scale limit. Verify area safety; check for high residual gas. W001 Calibration Due Pre-set calibration interval expired. Schedule and perform zero and span calibration. W005 Low Supply Voltage Input voltage has dropped below 16V DC. Check the power supply and cable run lengths. F160 Loop Fault The 4-24mA current loop is open or shorted. Inspect signal wiring connection at Terminal 3. Technical Specifications Summary Input Voltage: 16–32V DC (24V DC Nominal)

The Honeywell XNX Universal Transmitter is a versatile, high-performance gas detection platform that simplifies installation and maintenance across diverse industrial environments. By standardizing on a single transmitter for toxic, flammable, and oxygen gas detection, facilities can significantly reduce training time and spare parts inventory.

The LCD will light up and initiate a self-test routine. The display will show the current firmware version, the configured gas type, and the target full-scale range.

Check HART or Modbus wiring for loose connections. F112 Over-Range Gas concentration exceeded scale limit

There are four magnetic switches located around the display bezel: Up , Down , Escape (ESC) , and Enter ( ) . Accessing the Menu: Hold the magnetic wand over the Enter ( ) target for 3 seconds.
