Selection is possible between:
•Constant value control: the E-IPFC changes the pump speed so that the set
value stays constant depending on the water consumption.
•Fixed frequency control: the E-IPFC powers the pump at the set frequency.
•Constant value control with the two set values wanted, selectable by opening
or closing digital input 2.
•Fixed frequency control with the two frequency values wanted, selectable by
opening or closing digital input 2.
•In external frequency control mode, the motor frequency can be controlled by
an analogue signal connected to the AN4 input.
Alarm Max value
p = XX.X [bar]
8
Specifies the value that
can be reached in the
system beyond which, even
with a constant frequency
operating mode, the pump
gets stopped and an alarm
signal is issued. The pump
will only be restarted once
the measured value has
dropped below the maximum
alarm value for more than 5
seconds

Min. alarm value
p = XX.X [bar]
0
Specifies the minimum value
that can be reached in the
system below which, even
in a constant frequency
operating mode, the pump
gets stopped and an alarm
signal is issued. The pump
will only be restarted after
the measured value has
risen above the minimum
alarm value for more than 5
seconds
