P3.13.8.2 SOFT FILL FREQUENCY (ID 1055)
P3.13.8.3 SOFT FILL LEVEL (ID 1095)
P3.13.8.4. SOFT FILL TIMEOUT (ID 1096)
The drive operates at the soft fill frequency until the feedback value is equal with the soft fill
level. If the feedback value does not become equal with the soft fill level, during the timeout,
an alarm or fault shows. You can make a selection of the response with parameter P3.13.8.5
(PID Soft Fill Timeout Response).

9.12.6 INPUT PRESSURE SUPERVISION
Use the Input pressure supervision to make sure that there is enough water in the inlet of
the pump. When there is enough water, the pump does not suck air and there is no suction
cavitation. To use the function, install a pressure sensor on the pump inlet.
If the input pressure of the pump goes below the set alarm limit, an alarm shows. The
setpoint value of the PID controller decreases and causes the output pressure of the pump to
decrease. If the pressure goes below the fault limit, the pump is stops and a fault shows.
