Cavitation protection
Overview
Cavitation problem can damage the impeller of the pumps, reduce the output water flow and
cause unexpected noise. The cavitation protection will generate a fault/warning when
cavitation conditions are deemed to be present. If the converter gets no feedback from the
pump transducer, it will trip to prevent cavitation damage. This function saves the maintenance
efforts and extends the lifetime expectancy of the system.
