The Xnx does not ship with a pre-installed sensor to allow for customized configuration.
Remove the gas and exit the menu to return to monitoring mode. 6. Common Fault Codes Sensor missing or disconnected. F161: Calibration required or failed. W001: Warning that the unit is in "Inhibit" mode. Safety Warnings Xnx Universal Transmitter Quick Start Guide
Before touching a screwdriver, it is vital to understand what makes the Xnx "universal." Unlike single-gas detectors, the Xnx platform supports multiple sensor types (catalytic, electrochemical, infrared, PID) and communication protocols (4-20mA, Modbus, HART, Fieldbus). This guide focuses on the standard hardware setup, which applies to 90% of use cases. The Xnx does not ship with a pre-installed
Why is this important? Because in an industrial setting, the person holding this guide might be a technician in heavy PPE (Personal Protective Equipment), standing in the rain, with grease on their gloves. They don't want to read about the theory of 4-20mA loop signals; they want to know exactly which of the five terminal blocks the shield wire goes into. The guide respects the user's time and physical reality by relying on color-coding (e.g., matching the color of the wire to the color of the terminal block diagram).
