Input Pressure Supervision - Vacon 100 flow Applications Manual

PARAMETER DESCRIPTIONS
soft fill frequency (P3.13.8.2 Soft Fill Frequency) before the PID controller starts the
regulation.
P3.13.8.5 SOFT FILL FAULT (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.
0 = No action
1 = Alarm
2 = Fault (stop according to stop mode)
3 = Fault (stop by coasting)

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.
