The XNX Universal Transmitter supports three distinct sensor technologies: Electrochemical (EC), Infrared (IR), and Catalytic Bead (mV). It features a backlit LCD screen and a non-intrusive magnetic interface, allowing operators to configure and calibrate the unit in hazardous environments without opening the enclosure. Visual Indicators Normal operation. Yellow LED (Flashing): Fault or alarm state. Red LED (Flashing): Gas alarm threshold exceeded. 2. Mechanical Installation and Mounting
For advanced configurations (HART protocol, Modbus mapping, datalogging), refer to the full technical manual. However, for 95% of industrial applications, this guide is all you will ever need.
[ Power & Signal ] [ Options Pod / Relays ] 1: 24VDC (+) 1: Common (Fault) 2: 0VDC (-) 2: Normally Closed (Fault) 3: 4-20mA Output 3: Normally Open (Fault) 4: Earth Ground ... (Configurable Alarm Relays) Use code with caution. Wiring Steps

Remove the transit plugs and install certified cable glands (M20 or 3/4” NPT) in the appropriate entries. 3. Wiring and Electrical Connections
: Install the housing with the main sensor port pointing downward to prevent water or dust accumulation on the sensor element.
Minor issues or maintenance alerts. Output operates normally. The XNX Universal Transmitter supports three distinct sensor
Using the hex key provided (size 3mm), loosen the set screw on the main cover. Unscrew the cover counter-clockwise. Do not lose the O-ring—this is your environmental seal.
Adjust the span value displayed on the screen to match the exact concentration stamped on your calibration gas cylinder.
Attach the calibration weather housing or calibration adapter to the sensor. Yellow LED (Flashing): Fault or alarm state
Terminate the cable shield at the controller or power source end. Do not ground the shield at both ends to avoid ground loops.
Gently pull the display module forward and unclip its retaining tether to expose the terminal blocks underneath. Power and 4-20mA Signal Wiring (3-Wire Current Source)
