Soft pipefill
Filling up an empty system using normal PID control would cause a sudden pressure
peak. To avoid this, a soft pipefill function is available. This involves running the pump
at a lower speed until a predefined threshold of process actual value (for example,
measured pressure) is achieved. If a specified increase in the actual value is not
achieved within a specified time, pump speed is stepped up. This is repeated until the
