Page 61 Design and Function Operating points and control modes The controller SIGMA CONTROL 2 can operate in the following control modes: ■ DUAL ■ QUADRO ■ VARIO ■ CONTINUOUS ■ DYNAMIC Option C1 ■ MODULATING control DUAL In the DUAL control mode, the machine is switched back and forth between LOAD and IDLE to maintain the machine working pressure between the preset minimum and maximum values.
Page 62: Variable Speed Drive With Frequency Converter (Sfc)
If the network pressure falls below the TARGET value: SIGMA CONTROL 2 runs the motor up to a speed at which air delivery matches the air demand. The above description is valid only when the Pressure control option is set to Local mode: in the menu:10.1.1 Power switching .
Page 63: Modulating Control
The load and power consumption of the drive motor rises and falls with the air demand. To ensure optimal control on large compressors, the control air for the proportional controller is tak‐ en from an external air receiver.

For the mains contactor, the usage time is defined by the maximum permissible number of switching cycles. The mains contactor switching cycle counter in SIGMA CONTROL 2 records the number of switching cycles and generates a warning message when the maximum permissible number of switching cycles is exceeded.

Page 203: Excessive Temperature Shut-Down Test
SIGMA CONTROL 2 will simulate a higher temperature for checking this function. For this purpose, SIGMA CONTROL 2 automatically determines an offset value to be displayed. During the test mode, this offset is added to the actual airend discharge temperature to cause the machine to shut down prematurely.
