NOTICE: If the pump is provided alone, and not
integrated into a system installed by us, the con-
figuration mode upon delivery is the "speed stage
control"
mode.
"Speed stage control" mode (Fig. 2, 3)
• The duty point is obtained by manually adjust-
ing the speed stage via the menus or using an
external command signal for the speed stage
expressed in %.
• For entry into service, the motor speed stage
should be set at 2400 rpm.
"Constant pressure: pc" mode (Fig. 2D, 3D, 4D)
• In "p-c" mode, the converter maintains a con-
stant pressure at the pump discharge irrespective
of the delivery rate required by the installation.

The duty point is defined manually via the menus
or an external signal.
• This mode can be accessed when the
open hydraulic loop parameter is selected in
menu 5.7.8.0.
• A relative pressure sensor is used for control
(sensor: accuracy: ≤ 1 %; using between 30 %
and 100 % of the measuring range).
• For entry into service, the set pressure should be
set at 60 % of the pump's maximum pressure.
"Δp-c" mode (Fig. 2D, 3D, 4D)
• In "Δp-c" mode, the converter maintains a con-
stant differential pressure (generated by the
pump) irrespective of the delivery rate required
by the installation.
Δp-c
• The differential pressure is defined manually via
the menus or via an external signal.
• This mode can be accessed when the
closed hydraulic loop parameter is selected in
menu 5.7.8.0.
• A differential pressure sensor is used for control
(sensor: accuracy: ≤ 1 %; using between 30 %
and 100 % of the measuring range).
• For entry into service, the set pressure should be
set at 60 % of the pump's maximum pressure.

Mode "variable pressure: Δp-v"
(Fig. 2D-3D-4D)
• In "Δp-v" mode, the converter changes the dif-
ferential pressure of the pump in a linear manner,
in line with the delivery rate required by the
installation.
• The duty point (Pset) is defined manually via the
menus or an external signal.
• The duty point at a zero delivery rate (%Pset) is
defined manually via the menus.
• This mode includes zero delivery rate detection
that switches off the pump.
• A differential pressure sensor is used for control
(sensor: accuracy: ≤ 1 %; using between 30 %
and 100 % of the measuring range).
• For entry into service, the set pressure should be
set at 60 % of the pump's maximum pressure.
• This mode can be accessed when the
closed hydraulic loop parameter is selected
in menu 5.7.8.0.
"PID control" mode
• The converter enables control with another type
of sensor (temperature, delivery rate, etc.) via
control of the PID (proportional integral differen-
tial control).
• The duty point is expressed as a percentage of
the measurement range of the sensor used. This
point is defined manually via the menus or via an
external control signal.
