The Xnx menu is accessed via the glass-touch buttons under the display (Left, Up, Down, Right, Enter). Do not use sharp objects to press them.
Ensure correct span gas concentration and verify gas flow rate. Warm-Up Mode
In a standard environment, if you need to calibrate a device, you unplug it, open the casing, and press some buttons. In a Zone 1 or Zone 0 hazardous area (where explosive gases are constantly present under normal operations), taking a screwdriver to a device is literally asking for an explosion.
The screen will indicate a warm-up phase (indicated by a flashing clock icon or specific status code). Wait for the sensor to stabilize; this can take anywhere from 2 to 30 minutes depending on the gas cartridge type.
The XNX display shows specific code types when the unit encounters operational problems. Code Category Typical Action Xnx Universal Transmitter Quick Start Guide
The XNX features an advanced diagnostic system that displays fault and alarm codes if an anomaly is detected. Code / Status Description Corrective Action Sensor Fault
Typically configured as Normally Energized for fail-safe operation. 4. Sensor Installation and Cartridge Insertion
A Quick Start Guide (QSG) is designed to provide users with a fast and simple way to start using a product. Typically, a good QSG should cover:
Select your specific sensor technology (Catalytic, IR, or EC) and confirm. Reboot the transmitter if prompted by the system. 5. Calibration Procedure The Xnx menu is accessed via the glass-touch
Mount the transmitter in an area where gas is likely to accumulate, keeping it away from direct heat sources or high-vibration areas.
Allow the gas reading to return to zero before resuming normal monitoring mode to prevent false alarms at your controller. Troubleshooting Common Display Codes
Re-calibrate using a fresh, unexpired gas cylinder; check flow rate. No power or reversed polarity
If ambient air is completely free of contaminant gases, select start. If testing in an unpredictable environment, apply synthetic zero air via a calibration span cap at a flow rate of 0.5 Liters per minute (L/min). Warm-Up Mode In a standard environment, if you
For , insert the specific gas cartridge into the sensor housing and secure the locking ring. 4. First-Time Power Up and Configuration
When powered on for the first time, the XNX executes a self-test diagnostic routing to identify the connected gas sensor. Step 1: Language and Date Setup Swipe to open the main menu.
Feed a shielded, 3-wire or 4-wire instrument cable through the lower conduit entries.
Attach the calibration adapter to the base of the sensor cartridge.
Do not run the Xnx wiring in the same conduit as high-voltage AC power (motors, VFDs). Inductive noise will cause erratic readings.
Carefully thread the sensor body into the entry, ensuring the threads engage smoothly without cross-threading. Tighten securely to maintain the explosion-proof seal.
