: Fasten the transmitter to the wall or pipe bracket using the mounting lugs on the back of the enclosure. Ensure the unit is vibration-free. Electrical Connections and Wiring
Connect the internal earth ground terminal to a local instrument ground. Connect the external ground lug to a structural earth ground to minimize radio frequency interference (RFI) and electromagnetic interference (EMI). 4. Initial Power-Up and Configuration Once wiring is verified, apply 24V DC power to the unit.
Ensure the package contains the following items:
The XNX can be mounted using the integrated mounting holes on the back of the housing.
The sensor enters a warm-up phase (countdown timer varies by sensor type). The output signal is locked at 4mA (or a designated fault current) during this period. Xnx Universal Transmitter Quick Start Guide
The transmitter cannot communicate with the sensor cartridge. Check sensor pins and connection tightness.
: Verify the transmitter markings match your area's hazardous classification.
Which you are installing (EC, Pellistor/Catalytic Bead, or Infrared)?
Regular calibration is critical to maintaining safety and accuracy. Ensure you have the correct calibration gas cylinder, a fixed-flow regulator (0.5 L/min standard), and the XNX calibration adapter. Step 1: Access the Calibration Menu : Fasten the transmitter to the wall or
Only qualified personnel trained in industrial gas detection and local electrical codes should perform these procedures. 1. Mechanical Installation and Mounting
Do you require communication protocols?
Once stabilized, the display will transition to the standard monitoring screen, showing the current gas concentration, unit of measure, and a green status LED heartbeat. 6. Basic Interface Navigation
The Honeywell Xnx™ is a universal transmitter that supports a wide range of gas detection sensors. It is designed to interface with catalytic bead, infrared (IR), and electrochemical sensors. This guide covers the basic installation, wiring, and configuration required to get the unit operational. Connect the external ground lug to a structural
Use certified gas (recommended concentration = 50–60% of range).
Which are you using (Infrared, Catalytic Bead, or Electrochemical)?
Use the integrated mounting lugs on the XNX housing to mark the drilling holes.
