set a timeout for the soft fill function. If the set level is
not reached within the timeout a fault is triggered.
This function can be used e.g. to fill the empty pipe
line slowly in order to avoid "water hammers" that
could otherwise break the pipes.
It is recommended to use the Soft Fill function always
when using the Multi Pump functionality.
Code Parameter Min Max Unit Default ID Description
P3.13.8.1 Enable 0 1 0 1094
0 = Disabled
1 = Enabled
P3.13.8.2 SoftFill Freq 0.00 50.00 Hz 20.00 1055
The drive accelerates to this frequency
before starting to control.
P3.13.8.3 SoftFill Level Varies Varies Varies 0.0000 1095
The drive runs at the PID start
frequency until the feedback reaches
this value. At this point the controller
starts to regulate (depending on acting
mode).
P3.13.8.4 Timeout Time 0 30000 s 0 1096
If the desired value is not reached
within this time a fault or alarm is
created.
0 = No timeout (Note! No fault triggered
if value "0" is set)
P3.13.8.5 Timeout Response 0 3 2 738
0 = No action
1 = Alarm
2 = Fault (Stop according to stop mode)
3 = Fault (Stop by coasting)
Group 3.13.9: Input Press.Superv.
The Input pressure supervision function is used to
supervise that there is enough water in the inlet of the
pump, to prevent the pump from sucking air or
causing suction cavitation. This function requires a
pressure sensor to be installed on the pump inlet, see
fig. Location of pressure sensor.
If the pump inlet pressure falls below the defined
alarm limit, an alarm will be trigged and the pump
output pressure reduced by decreasing the PID
controller setpoint value. If the inlet pressure still
keeps falling below the fault limit, the pump is
stopped and a fault will be triggered.
