Parameter Description Help text Possible settings Unit Factory setting
3-9-8-2 Time Constant for
Attenuation of
Estimated Flow Rate
Values
Time constant for attenuation of estimated
flow rate values. The time constant makes it
easier to read the display value on the
control panel and is required for sensorless
flow rate control.
0,0 … 600,0 s 5,0
3-9-9 Waste Water Function
3-9-9-1 Flow Velocity
Monitoring
Activates flow velocity monitoring.
Depending on the selection made, a
warning is output when the value defined
in 3.9.9.2 is undershot, and the pipe
flushing function may also be started.
OffWarningWarning + Pipe flushing OFF
3-9-9-2 Minimum Flow Velocity The minimum flow velocity set here must be
undershot for a configurable period of time
so that the pipe flushing function starts or a
warning is displayed, depending on the
configuration.
0,0…10,0 m/s 2,0
3-9-9-3 Time Delay, Flow
Velocity Monitoring
Configurable period of time for which the
minimum flow velocity must be continually
undershot so that the pipe flushing
function starts.
0…168 h 24 h 24
3-9-9-4 Duration of Pipe
Flushing
Duration of pipe flushing cycle. Period of
time during which alternative control is
active
0 …120 min 2
3-9-9-5 Pipe Flushing Flow
Velocity
Flow velocity value during flushing 0,0…5,0 m/s 4,0
3-9-9-6 Inside Pipe Diameter of
System
Pipe diameter of system 0…5000 mm 0
3-9-9-7 Pump Start at Maximum
Speed
Start-up along a ramp up to maximum
speed and maintaining maximum speed for
the duration of a defined period of time.
The function is run or executed at every
start to prevent deposits in the pump sump
and in the piping.
OFF / ON OFF
3-9-9-8 Duration of Maximum
Speed
Configurable period of time for which the
frequency inverter maintains maximum
speed
0,0…600,0 s 180,0
