Xnx Universal Transmitter Quick Start Guide Direct

Once your Xnx is online, schedule a full calibration (span gas) within 48 hours of installation. The quick start gets you running; the calibration keeps you safe.

If your unit includes the local relay option, wire your external alarms or horn/strobe units to the dedicated relay terminal slots:

Regular calibration is critical to maintaining safety and accuracy. Ensure you have the correct calibration gas cylinder, a fixed-flow regulator (0.5 L/min standard), and the XNX calibration adapter. Step 1: Access the Calibration Menu

The XNX features an onboard diagnostic system that outputs distinct error codes on the LCD screen to assist in rapid troubleshooting. Error Code Description Corrective Action Sensor Fault Sensor cartridge missing or disconnected. Power down, verify sensor seating, and restart. F112 Over-Range Gas concentration exceeded scale limit. Verify area safety; check for high residual gas. W001 Calibration Due Pre-set calibration interval expired. Schedule and perform zero and span calibration. W005 Low Supply Voltage Input voltage has dropped below 16V DC. Check the power supply and cable run lengths. F160 Loop Fault The 4-24mA current loop is open or shorted. Inspect signal wiring connection at Terminal 3. Technical Specifications Summary Input Voltage: 16–32V DC (24V DC Nominal) Xnx Universal Transmitter Quick Start Guide

Use certified gas (recommended concentration = 50–60% of range).

: Allow at least 6 inches (150 mm) of clearance below the sensor for calibration cup attachment and sensor replacement.

The XNX enclosure features five conduit entries (metric M25 or imperial ¾” NPT) to allow flexible routing for power, signal, and optional relay connections. 1. Enclosure Grounding Ensure you have the correct calibration gas cylinder,

Holds the magnet used to trigger the screen sensors.

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.

Swipe the magnetic wand over for 3 seconds to access the main menu. Enter the security passcode (default is 0000 ). Navigate to General Settings > Sensor Type .
