Fault code 5 means AIR XS internal memory is at 100% capacity and requires erasing.

AIR XS is designed for environments where hazardous RCS is present, but the manual states that RCS detection can be influenced by particle orientation, shape, size, and overall dust loading.
The device must be operated within its technical limits, and continuous operation at temperature extremes may reduce product life.
Yes. The manual states that AIR XS may show cross-responsivity from poly-crystalline particles in the local environment, with severity depending on particle density and crystalline properties.
Because of these possible interferences, the manual frames AIR XS as an indicative real-time monitoring device rather than a regulatory compliance method.
The AIR XS manual notes that test and calibration assumptions include a controlled environment, consistent temperature and humidity, evenly distributed particles, laminar airflow through the sensor, particles moving at constant velocity, and the reference device being treated as the basis for comparison.
Real site conditions may differ from those assumptions, which can affect observed readings.
Mount AIR XS vertically on a suitable surface using the integrated mounting brackets. Isolate power before electrical connections, ensure the supply matches the rating plate, run cables through the bottom cable glands, wire to the relevant terminals, tighten glands to maintain the IP seal, and close and lock the door after use.
Ensure the particulate entry and exit ports are not restricted or covered.
The AIR XS technical specification lists nominal power supply options of 100 V AC to 240 V AC at 50/60 Hz, or 9 V DC to 18 V DC.
The product also provides two 15 V DC 1 A external power outputs for powering external devices.
AIR XS supports MODBUS/RTU via RS485 and MODBUS/TCP via Ethernet. The default MODBUS address is 1, default baud rate is 115200, parity is none, stop bits are 1, and Ethernet IP assignment is dynamic DHCP.
RS485 and Ethernet settings can be viewed or changed from Main Menu > Communication.
Open Main Menu > Communication. Use the RS485 or Ethernet submenu to view settings through Details or change them through Configure.
If floating point byte order is not compatible with the receiving system, change the byte ordering from Main Menu > Communication > RS485/MODBUS > Configure.
AIR XS input registers include product TX number, firmware version, serial number characters, live RCS, RCS averages for 15 minutes, 1 hour, 4 hours, 8 hours, a register that differs by firmware version for 12 hours or 1 minute, live flow rate, temperature, humidity, internal voltage, and alarm status.
Use the register table in the manual when integrating with SCADA or a MODBUS client.
AIR XS has two user-configurable alarms for warning of a selected particulate threshold breach. From Main Menu, select Alarms, use Detail to view current alarms, and Configure to set channel, threshold value, latching or non-latching mode, and units.
