The default factory passcode is 0000 . Use the Up and Down targets to change digits, and Enter to confirm each field to access the configuration menus. 7. Zero and Span Calibration Quick Steps
Mount the unit with the sensor pointing directly downward to prevent water accumulation or dust blockages on the sensor flame arrestor.
Bolt the XNX firmly to the mounting surface or pipe clamp assembly using M10 or 3/8-inch steel fasteners.
The analog signal can be configured as Source, Sink, or Isolated. Adjust the onboard physical hardware switches to match your controller topology: : 4-24mA Loop Signal Output. Ensure loop resistance does not exceed 500 ohms at 24V DC. Optional Relay and Digital Connections Xnx Universal Transmitter Quick Start Guide
The grounding symbol used in the wiring diagram is not explained. A note specifying whether chassis ground, earth ground, or signal ground is intended would prevent confusion.
: Position the main housing vertically with the sensor pointing down.
: The XNX EC sensors employ the patented Reflex™ cell fault diagnosis routine, which checks for cell presence, cell dry‑out, and cell open or short circuit. Reflex™ is automatically initiated by the transmitter every eight hours, as well as on power‑up or sensor exchange. The default factory passcode is 0000

Turn off the gas, remove the calibration cup, and wait for the gas value to return to normal before returning the loop to service. Troubleshooting Common Fault Codes The XNX display indicates errors with distinct fault codes.
The XNX features five conduit entries (M20 or 3/4-inch NPT) to separate power, signal outputs, and remote sensor connections. Zero and Span Calibration Quick Steps Mount the
The XNX transmitter can be pipe-mounted, wall-mounted, or ceiling-mounted using the integrated mounting lugs.
The Xnx Universal Transmitter can be installed in a variety of configurations, including wall-mounted, panel-mounted, or pipe-mounted. Here are the general steps for installing the device:
