Official Kaeser documentation is often serialized and tailored to specific units. You can find comprehensive community-uploaded versions at the following sites:
Stops the compressor. The machine may idle for a short period to vent internal pressure before stopping completely.
The screen displays erroneous pressure values (e.g., 0 bar or maximum pressure instantly) or a sensor communication error.

One of the primary roles of a control system is to minimize "unloaded" running time—periods when the motor is spinning but not producing air, which wastes significant electricity. The Sigma Control Basic utilizes to automatically switch the compressor between full load, idle, and standby based on actual demand. By maintaining narrow pressure ranges and enabling automatic shutdowns during low demand, the system significantly reduces energy consumption and extends the machine's lifespan.

Switches the machine predictably back and forth between full and IDLE states. When the maximum network cut-out pressure is reached, the intake valve seals, venting the oil separator tank so the motor draws minimal current. Once a fixed idle timer expires, the machine switches fully into STANDSTILL until system pressure drops below the minimum limit. QUADRO Control Mode
