13 Altivar Process 600 variable speed drives Pump Functionality Introduction Cavitation Pump Protection Functions used to prevent cavitation which can damage the pump impeller, reduce flow, create vibration, and increase energy consumption. Dry Running Pump Protection Detects pump operation in a dry running condition to avoid severely damaging or destroying the pump. No Flow/ Low Flow Pump Protection Detects pump operation at no flow or low flow to avoid severely damaging or destroying the pump by overheating PID Feedback Supervision Keep pump running point in right running area. Prevention of burst pipe High Flow Protection Detection of Pipe Burst. Detect running outside normal working area Inlet Pressure Protection Protects the pump against low inlet pressure. When the inlet pressure goes below the settable pressure, the applied pressure setpoint is decreased by the drive itself to prevent cavitation. If the pressure setpoint is reduced, the pump speed will also decrease. Outlet Pressure Protection This protection provides outlet "high pressure" and "low pressure" alarms. Used to prevent pipe system damage or to detect burst pipes. Low Pressure Pump Protection Detects pump operation at low pressure in order to avoid pump damage due to cavitation.
