Xnx Universal Transmitter Quick Start Guide

The XNX Universal Transmitter Quick Start Guide serves as a field reference for installing and configuring the Honeywell XNX platform, focusing on supporting Electrochemical, Infrared, and Catalytic Bead sensors. It provides critical instructions for hazardous location compliance, including wiring, mounting, and using magnetic switches for non-intrusive operation.

Adjust the displayed span value using the arrows to match the exact concentration printed on your calibration gas cylinder.

Perform a zero calibration. If using a toxic sensor, perform a span calibration using the appropriate calibration gas. Troubleshooting Common Issues

To navigate the menus without breaking the explosion-proof seal, swipe the provided magnetic wand over the four target areas on the glass cover:

Connect alarm relays (A1, A2, Fault) if required for local alarm annunciation. Xnx Universal Transmitter Quick Start Guide

Connect via pluggable, color-coded terminal blocks (12 to 28 AWG wire). Ensure you use only certified M25 cable glands to maintain the unit's explosion-proof rating.

Working with gas detection equipment requires strict adherence to safety protocols to prevent personal injury and equipment damage.

: Mount the unit with the sensor pointing downwards to prevent water accumulation and dust build-up.

Leave sufficient clearance beneath the unit to allow for sensor cartridge replacement and calibration adapter attachment. Mounting Steps The XNX Universal Transmitter Quick Start Guide serves

Distance requirements depend on wire gauge, power supply voltage, and whether transmitters are daisy‑chained. Always verify voltage at the transmitter terminals—it must remain within the specified range under all operating conditions.

The external controller drives the loop current. Connect the jumper so Terminal 1 returns current to the 0V common line. 4. Optional Relay Wiring (If Equipped)

Before handling the equipment, observe the following safety protocols to prevent personal injury or damage to the device:

Mount the transmitter in an area where gas is likely to accumulate, keeping it away from direct heat sources or high-vibration areas. Perform a zero calibration

Always isolate and lock out power sources before opening the transmitter enclosure in a hazardous area.

For rapid setup of gas detection with Xnx (HART/analog/modbus versions).

Only trained, qualified service personnel should install, wire, configure, or service the XNX Universal Transmitter.
