More about the XAIR Expert controller

Designed for use with any brand of equipment with motor power up to 500 kW: oil-injected screw compressors and other machines based on individual algorithms. Users rate it as exceptionally intuitive, even for the most complex processes and settings. Thanks to its ease of use, many users emphasize that using the XAIR Expert controller doesn’t require constantly referring to the manual, which significantly improves workflow efficiency and reduces the risk of incorrect parameter entry.

The clear interface supports operators, facilitating compressor management and rapid issue diagnosis.

Modern monitoring and diagnostics

The XAIR Expert controller is equipped with an advanced remote monitoring and diagnostic system via a built-in Webserver, which can be activated with a code. This unique solution on the market provides maximum control over communication and industrial data transmission. The system enables full, visualized real-time analysis of the compressor’s operation, allowing maintenance managers to continuously monitor all working parameters, analyze individual function settings like the compressor work schedule, and review messages reported by the device.

Advantages of the Webserver:

  • Real-time monitoring: The Webserver provides current information on compressor operating parameters, sensor readings, and energy consumption. This allows continuous tracking of compressor operation and control over settings such as work schedules and error reports.
  • Secure hosting: The system can be hosted directly on an internal LAN network, ensuring high cybersecurity. Local data transmission eliminates risks associated with external clouds and servers, offering full control over information and avoiding issues related to internet outages.
  • Convenient data access: Thanks to mobile access, users can monitor compressor parameters from any location.
  • Secure communication: The system ensures authorized data transmission via VPN, allowing secure external communication.

User-friendly operation

A major convenience is the display of inverter messages and faults directly on the controller. The XAIR Expert shows clear and readable messages, helping operators quickly understand the situation. This is especially useful for inverter events that typically use codes like “E01.” The XAIR Expert displays full, understandable descriptions, e.g., “E01 Power supply asymmetry error.”

International support in XAIR Expert controllers

The XAIR Expert controller offers comprehensive functionality with language support in:

  • Polish
  • English
  • German
  • Russian

This allows users from different countries to operate the device in their preferred language. Additionally, the controller can be adapted to other language versions in agreement with the manufacturer, providing global usability and support.

Network operation in Master & Slave mode

The XAIR Expert controller allows for networked operation, enabling efficient management of multiple compressors in one system. In this setup, one controller acts as the Master, while others operate as Slave controllers.

Using the Modbus RTU protocol, communication between devices is fast and reliable. The system allows for synchronization of compressor operations, optimizing performance and reducing energy consumption.

Main benefits of XAIR Line network operation:

  • Compressor coordination: Automatic regulation of starting and stopping units based on compressed air demand.
  • Energy optimization: Eliminates unnecessary idle work and balances compressor loads.  
  • Easy configuration: Quick assignment of Master-Slave roles without hardware modifications. 
  • Stable communication: Modbus RTU ensures reliable data transmission and device monitoring.

The XAIR network system is an ideal solution for companies seeking intelligent compressor control, increased energy efficiency, and better control over the pneumatic system.

Inputs and Outputs

The XAIR Expert controller offers a wide range of functions and flexibility thanks to its advanced I/O set. Its compact housing includes:

  • 4 RTD temperature inputs configurable for various sensor types (PT100, PT1000, KTY84, PTC), allowing monitoring of parameters such as oil temperature, motor temperature, outlet air temperature, and ambient temperature.
  • 3 analog inputs for 4–20 mA sensors and 1 analog input for a 5A current transformer, offering flexibility in measuring pressure, dew point, and other values.
  • 8 digital inputs for binary signals with configurable logic, and 9 digital outputs (relay) with functions like power control, fan control, or alarm signaling.
  • 2 USB ports and 1 Ethernet port for additional connectivity and integration.

Detailed I/O specifications are available in the product catalog.

System updates via USB port

The XAIR Expert controller is equipped with a USB port for easy and convenient system updates. This allows the device to regularly receive new features and software improvements, ensuring long-term support and adaptability to users’ evolving needs.

USB port functions also include:

  • Exporting service statistics: Users can export detailed compressor performance data, simplifying diagnostics and performance analysis.
  • Backup and restore settings: This function allows full configuration backup and quick restoration in case of failure or when transferring settings to another device.

DThese solutions ensure that the XAIR Expert controller provides not only reliability but also high user comfort and full control over compressor operation.
