Kaeser Sigma Control 2 compressor

The Kaeser Sigma Control 2 (SC2) is equipped with its own industrial PC as standard, including a web server, allowing direct communication with the compressor via intranet/internet. Password-protected compressor settings and operational data can be called up and adjusted on any PC with an internet browser without the need for software. Compressor operation and maintenance are therefore made even easier, as is regular monitoring of cost and energy efficiency.

The large operating panel has an LED backlit, 256 x 128 pixel, greyscale LCD screen on which plain text messages can be easily read across eight 30-character lines. Nine LED indicators signal additional operational parameters and conditions, and 13 membrane keys labelled with easy-to-understand icons ensure unmistakeable input of the various commands.

The operating panel communicates directly with the control system, the core of the Sigma Control 2. It comes with four interfaces for active and passive communication: IO-BUS for up to six I/O modules within the compressor; Sigma Frequency Control speed controllers, enabling the use of infinitely variable, frequency speed control for the compressor and for fans; an RJ45 ethernet interface (10/100 Mbps); and plug-in communication modules available for Profibus, Modbus, ProfiNet or DeviceNet.

An SD card slot is available for data transfer as well as for software updates onto the SC2 using pre-loaded SD cards. Updates can be carried out quickly while all operational settings are retained. Integrated RFID functionality ensures secure login for users or Kaeser service engineers, and safeguards the system against unauthorised changes or operation.
