Dry run protection
The Dry run protection function can be used to protect the pump from getting dry.
The figure below illustrates the operation of dry run protection function.
The dry run can be detected using the underload curve, low level mechanical switch
and pressure sensor.
•
Underload curve
- Detects the pump from getting dry and generates a warning or
fault.
•
Low/high level mechanical switch
- Indicates the water level in the pump
system through a digital input and generates a warning or fault.
•
Pressure sensor
- Connected to Supervision 1...3 through an analog input. The
output of supervision indicates the pump inlet getting dry and generates a warning
or fault.
