66 Program features
The digital high level and low level sensors can be used to generate a warning or fault
when the water level in the container raises or falls to the abnormal operation area.
The analog level sensor connected to an analog input measures the water level.

Soft pipe fill
The Soft pipe fill function can be used to fill a empty pipe softly. The function can
avoid sudden charge of water and rise in pressure in a closed valve or a nozzle at the
end of the pump system.
The figure below illustrates the operation of the Soft pipe fill function.
If the pumping system is leaking or is damaged then the setpoint will not reach in
time. To detect such a condition, you can enable soft pipe fill supervision to generate
a warning or a fault. The time is calculated with the last reference change in
parameter 40.03 Process PID setpoint actual.
