xnx xnx transmitter installation manual XNX Transmitter Installation Manual (Complete Guide) Introduction The Honeywell XNX Universal Transmitter is a highly flexible gas detection transmitter designed for industrial environments. It supports multiple sensor types (Electrochemical, IR, and mV) and communication protocols such as Ú‒ØÖ mA, HART, Modbus, and Foundation Fieldbus. This guide summarizes the key steps from official manuals and quick-start guides to help you install, wire, configure, and safely operate the XNX transmitter. ×. Before You Begin (Important Safety Notes) Before installation, always: • Read the full Technical Manual (×ßßÞMÖÝÙÞ) carefully • Ensure installation is performed by qualified personnel only • Follow all hazardous area safety standards • Use proper ESD protection when handling electronics Key Requirements: • Use only certified MØÛ cable glands • Use shielded, armored cables • Ensure proper grounding and bonding • Confirm compatibility with the selected sensor type Ø. Mounting the XNX Transmitter A. Choosing Installation Location Select a location based on gas type: • Heavier-than-air gases → install near ground level • Lighter-than-air gases → install at higher elevation • Avoid: ◦ High vibration areas ◦ Extreme temperatures ◦ Direct water exposure B. Mounting Options The XNX supports multiple mounting methods: • Wall mounting (standard) • Pipe mounting (optional kit) • Ceiling mounting Basic Steps: × . Use the mounting lugs on the enclosure Ø . Secure with appropriate bolts Ù . Ensure the unit is mounted upright and stable Ù. Wiring the XNX Transmitter A. Power Supply • Typical input: ØÚV DC • Ensure stable and regulated power source B. Communication Wiring The XNX supports multiple outputs: ×. Ú‒ØÖ mA Output • Standard analog signal for gas concentration • Connect to control system or PLC Ø. HART Communication • Allows configuration and diagnostics • Requires HART-compatible device Ù. Modbus / Fieldbus • Digital communication for advanced systems • Follow specific wiring diagrams for each protocol C. General Wiring Guidelines • Use shielded cables to reduce interference • Keep signal and power cables separate • Properly tighten cable glands to maintain IP rating • Apply anti-seize compound on threaded connections (as recommended) Ú. Sensor Installation The XNX supports different sensor “personality boards” : A. Sensor Types • Electrochemical (EC)‒ toxic gases (e.g., CO, H₂S) • Infrared (IR)‒ hydrocarbons and combustible gases • Millivolt (mV)‒ catalytic sensors Installation Steps: × . Insert the correct sensor module Ø . Connect to the appropriate terminal block Ù . Ensure proper alignment with the personality board Ú . Tighten securely to avoid signal loss Û. Powering Up the Device First-Time Startup: × . Double-check all wiring connections Ø . Apply power (ØÚV DC) Ù . Wait for system initiali
