Time interval for updating the set value as a function of
compensation.

Minimum frequency below that the pump must try to
stop following the control ramp (Control ramp).

Stop delay
t = XX [s]
5
Delay with which the pump is attempted to be stopped
below the minimum control frequency (Freq.min.con-
trol ).
x
x
Control ramp
t = XX [s]
40
Time in which the device decreases the motor power
frequency from the minimum control frequency
(Freq.min.control ) to the minimum motor frequency
( Min motor freq.). If during this time the measured val-
ue falls below Set value - Delta control, the device re-
starts the motor. Otherwise the device will stop the mo-
tor completely following the control ramp (Control
ramp).

Delta start
p = XXX.X [bar]
0.5
This parameter communicates by how much the meas-
ured value must fall from the set value for the previously
stopped pump to be restarted.
x
x
Delta control
p = XXX.X [bar]
0.1
This parameter communicates by how much the meas-
ured value must fall in relation to the set value so that
the pump, during shutdown in control ramp, is restarted.

This parameter represents the increment of the meas-

ceeded in order for there to be a forced shutdown of the
pump according to the stop ramp.
