Pipe fill ramp
XXX [s]
=
Ramp up
time
Ramp time to follow after a start if the measured value is lower
than the minimum alarm value. The piping filling ramp expires
after the set time or if the measured value reaches the set
value.
In COMBO mode, only one unit is enabled to operate as long
as the filling ramp is active.

Set value
p = XXX.X [bar]

Compensation at the maximum frequency. The sign can be
reversed via the green key.

1: sensor; 2: Compensation ; 3: Set value ; 4: Min motor fre-
quency; 5: Max motor frequency
In the case of a group of pumps in COMBO mode, the com-
pensation must be referred to each pump.

Compensation set 2
p = XX.X [bar]
0
Compensation at the maximum frequency. The sign can be
reversed via the green key.

Value set update
t = XX [s]
5
Time interval for updating the set value according to the com-
pensation.

Operating frequency
f = XXX [Hz]

Max mo-
tor fre-
quency
Frequency used by the device to power the motor.

Frequency min control
fmin = XXX [Hz]
50
Minimum frequency below which the pump must try to stop
following the control ramp (Control ramp).
x
x
Stop delay
t = XX [s]
5
Delay during which an attempt is made to stop the pump below
the minimum control frequency (Frequency min control).
x
x
Control ramp
t = XX [s]
40
Time in which the device decreases the motor power frequen-
cy from the minimum control frequency (Frequency min con-
trol) to the minimum motor frequency (Min motor frequency).
If during this time the measured value falls below Set value -
Delta control, the device restarts the motor. If not, the device
will stop the motor completely following the control ramp (Con-
trol ramp).
x
x
Delta start
p = XXX.X [bar]
0.5
This parameter communicates by how much the measured
value must fall from the set value for the previously stopped
pump to be restarted.
