CavtProt: Cavitation Protection
This section describes the CavtProt function block that helps to avoid operating the VS and FS pumps in a cavitation situation. To achieve this, it monitors the suction pressure and adapts the pressure setpoint, if necessary.
NOTE: A pressure sensor providing absolute pressure values is required to implement this function.
