: Never open the XNX enclosure while under power unless the area is confirmed to be non-hazardous. Power Supply
To get started with the Xnx Universal Transmitter, follow these steps:
Mount the transmitter in an area where gas is likely to accumulate, keeping it away from direct heat sources or high-vibration areas.
If your model includes the optional relay module (three Form C SPDT relays for Alarm 1, Alarm 2, and Fault) or the Modbus/Foundation Fieldbus options, connect these lines to the secondary terminal strip located on the internal interface board. 4. Front Panel Interface and User Navigation
Before handling the equipment, ensure all safety protocols are met.
The transmitter will execute a 30-second diagnostic self-test, displaying firmware versions and sensor configurations.
Steps progress naturally:
Apply 24V DC power to the unit. The XNX will initiate a self-test routine, which includes: Flashing the diagnostic LEDs. Displaying the internal software version. Testing the LCD backlight. Running a sensor initialization countdown.
Turn off the gas, remove the calibration adapter, and allow the sensor to return to clean air before exiting the menu to avoid false alarms. 7. Common Fault Codes and Troubleshooting Fault Code Action Required Sensor Under-range Recalibrate the zero point in clean air. F116 Calibration Overdue Perform standard field calibration. F154 Sensor Fault Check sensor connections or replace the sensor cartridge. F161 Supply Voltage Low
The is an abbreviated reference designed for the rapid installation, operation, and maintenance of the XNX gas detection system. It is intended for use with various sensor technologies, including electrochemical (EC), infrared (IR), and catalytic bead (mV) sensors. Essential Installation & Mounting
Swipe to accept the zero point. The display will show a "Zero Passed" message. Step 2: Span Calibration
Connect the calibration gas cylinder to the sensor housing. Open the regulator valve to apply gas.
Feed a shielded, 3-wire or 4-wire instrument cable through the lower conduit entries.
