— O time between startup: compressor o for minimum switch-o time;
Mode control = indicates the control mode; this mode can be:
— Error: the compressor signals an error condition;
— Calibration mode: compressor in calibration stage (support only);
— Manual mode: compressor active in manual mode (support only);
— Analog mode: not used;
— Modabus mode: compressor active via command of the pCO board;
— Chiller mode: not used;
Status = indicates the current status of the compressor, it can be:
— o: compressor o;
— Locked out state: situation after an alarm has ceased;
— System Resetting: the compressor is in reset stage;
— Ramping Up: the compressor is in start-up stage;
— Partially Closed Vane: the compressor is closing the IGV valve;
— Normal Operation State: the compressor is operating normally;
— Maximum Flow State: the compressor is operating at full speed;
