P3.13.8.5. PID SOFT FILL TIMEOUT RESPONSE (ID 748)
Use this parameter to select the response of the drive to a 'PID Soft Fill' fault.
If the PIDFeedback value does not reach the set level in the time limit, a soft fill fault occurs.
10.14.9 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.
