Integrated intelligence: The next dimension

KAESER KOMPRESSOREN’s revolutionary modular concept takes compressor controllers to the next level and beyond. Welcome to the world of Sigma Control 2.

One size fits all

The SIGMA CONTROL 2 features a highly flexible modular design, yet its standard construction means that this versatile control system can be matched to suit the needs of any rotary screw compressor from KAESER KOMPRESSOREN’s extensive range.

Comprising a main control unit and separate input/ output modules, this modular concept therefore enhances communication and user-friendliness.

Integrated web server

The SIGMA CONTROL 2 is equipped with its own web server, making it possible to communicate with the compressor via intranet/Internet.

Operational data and maintenance and alarm messages can therefore be viewed, with password protection, from any PC running a standard Internet browser. This feature consequently simplifies operation and maintenance for example.

Flexible communication

SIGMA CONTROL 2 communicates internally with the compressor via input/output modules that are tailored to meet the specific needs of the various compressor ranges; this future-proof concept therefore offers exceptional flexibility.

Moreover, Ethernet interfaces and numerous plug-in bus communication modules enable external communication with utilities management and centralised control systems.

Security with RFID

SIGMA CONTROL 2 provides high level security with its integrated RFID (Radio Frequency Identification) functionality.

Not only does this technology ensure secure log-in for users and/or KAESER service engineers, but also safeguards the system against unauthorised changes or operation. Manufacturer-provided passwords are no longer required.

The intelligent way to save energy

With multiple compressor control modes, a timer and base-load sequencing function, compressor energy consumption is now lower than ever before.

The precision electronic pressure sensor enables exact switching differential selection to meet requirement thereby ensuring further savings.

Modular design – Dependable performance

The control centre

The control unit features an easy to read display and durable input keys; all relevant information can be viewed at a glance. User-friendliness is further enhanced by the logical menu structure coupled with the ability to display data in any one of 30 selectable languages

Stay connected

The Ethernet interface (10/100 MBbit/sec) allows users to directly call-up operational parameters via a connected PC network. Optional communications modules support Modbus-RTU, Modbus/ TCP, Profibus DP-VO, DeviceNet and ProfiNet IO.

Your security

The addition of RFID functionality to the SIGMA CONTROL 2 means that service work and system changes to the compressor can be performed only by authorised personnel, e.g. suitably qualified KAESER service partners.

Manufacturer-provided passwords are not required.

Update and save

Software updates and operational parameters can be quickly uploaded and transferred via the convenient SD card slot.

This both minimises service costs and allows the SD card to be used for (long-term) storage of key operational data.
