Q: What are some common issues with the Xnx Universal Transmitter? A: Common issues include device not responding, inaccurate measurements, and communication issues.
The XNX interface is operated entirely non-intrusively via four magnetic switches on the glass display cover. Use the provided magnetic wand to activate the contacts: : Exit current menu or cancel an entry. Xnx Universal Transmitter Quick Start Guide
: Ensure the housing, threads, and O-rings are free of debris, damage, or corrosion. Mechanical Installation and Mounting
Position the unit based on the target gas density. Place it low for heavy gases like Hydrogen Sulfide ( H2Scap H sub 2 cap S ) and high near the ceiling for light gases like Hydrogen ( H2cap H sub 2 ) or Methane ( CH4cap C cap H sub 4 Mounting Steps
Connect to Xnx for Configuration
Wire the for the 4-20mA analog loop signal output.
Use the integrated mounting lugs on the XNX housing to mark the drilling holes.
The XNX supports three primary sensor technologies: Electrochemical (EC), Infrared (IR), and Catalytic Bead (mV). Turn on the power supply
Define the full-scale measurement range (e.g., 0-100% LEL or 0-50 ppm) and the appropriate engineering units.
The Xnx Universal Transmitter can be configured and programmed using various tools and software. Some of the key configuration options include:
Configurable Normally Open (NO) or Normally Closed (NC). Relay 2 (Alarm 2): Configurable NO or NC. (Standard 4-20mA, HART, Modbus, or Foundation Fieldbus
Ensure the unit is properly grounded to prevent EMI interference. 3. Powering Up
