Before wiring the XNX, always power off the transmitter. Key points include:
Holds the magnet used to trigger the screen sensors.
You perform a quick "bump test" by applying a known concentration of gas. The transmitter displays the reading, confirming the pre-calibrated sensor is communicating correctly with the main board without needing a full span calibration. Key Quick-Start Specifications Power Supply 16 to 32 VDC (sensor dependent) Communication 4-20mA with HART (standard); Modbus or Fieldbus (optional) Display Backlit LCD with text, bar graphs, and status icons Mounting Surface lugs, pipe mount (2–6"), or ceiling bracket Operating Temp -40°C to +65°C (-40°F to +150°F) Important Maintenance Tips Xnx Universal Transmitter Quick Start Guide
For further details, refer to the complete user manual provided in the packaging or visit the manufacturer's website.
However, the guide subtly proves why this analog standard is bulletproof. A 4-20mA signal doesn't care about electromagnetic interference from massive turbines. It doesn't suffer from latency. If a wire gets cut, the current drops to 0mA, Before wiring the XNX, always power off the transmitter
Routine calibration ensures measurement accuracy and sensor health.
The large, backlit LCD provides:
Navigate to to set the trip points for Alarm 1 and Alarm 2, as well as their behavior (latching/non-latching, energised/de-energised). First-Time Calibration
Apply the span gas from the cylinder regulated to 500 mL/min. Optional Relay Wiring (If Equipped)
: Mount near potential leak sources or in the breathing zone.
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)
