5 Design and Function
5.1 Controller overview
SIGMA CONTROL 2 controls, regulates, monitors, and protects the machine.
All parameters needed to operate KAESER rotary screw compressors can be set and displayed
using the controller. Various user-dependent password mechanisms protect the parameters.
Components
SIGMA CONTROL 2 has the following components:
■ Main Control System (MCS):
─ Industrial PC
─ Software for the control, regulation, and monitoring of the machine, for the display and mod‐
ification of settings and for communication.
─ User interface with backlit display, touch keys, LEDs, and interfaces.
─ Radio Frequency Idenfication (RFID):
Identification with RFID Equipment Card
─ Slot for customer interface; optional communications module
─ SD card slot for SD/SDHC cards:
Manual loading of updates with an SC card, reading or recording process data
■ Main Control System Input Output (MCSIO) [only SIGMA CONTROL 2 FLUID]:
─ As with MCS, but with:
─ integrated digital and analogue inputs and outputs
─ Without slot for customer interface
■ Input-Output-Module (IOM):
For SIGMA CONTROL 2 (Prepared for connection to control centre): modules with digital and
analogue inputs and outputs with autonomous power supply.
