be modied and select
(enter), with the buttons
(plus) or (minus) increase or decrease
the value. From this moment the setup icon start
blinking until the value is conrmed with
(enter).
To exit the program, push (menu) until when
you arrive to the basic display.
When you go in the setup mode icon will appear.
Example of parameter variation.
In order to modify the set-point pressure from 3.0
bars to 2.8 bars:
Select
(menu) and then with the buttons
(plus) or (minus) until you move to programming
parameter UP. Conrm with (enter) and then
with the buttons (plus) or (minus) move
to the parameters UP06. Conrm with (enter)
and then with the buttons (plus) or (minus)
change the value up to the desired value. From this
moment the setup icon will start blinking until the
value is conrmed with
(enter).
To exit the program, push (menu) until you
arrive on the basic video, when you exit the setup
mode the icon will disappear.
8.5. Password insertion
To enter on a menu with password, four numbers
appear on the display, the number to insert is
blinking. By pushing buttons
(plus) or
(minus) you can change the blinking. If you conrm
with (enter) the next number start blinking.
If the password is correct you can enter on the
MENU, if the password is wrong the rst number
restart blinking. To exit the program, push
(menu) until you arrive to the basic display, when
you are out from the setup mode the setup icon will
disappear.

8.6. Factory reset
This parameter allows to reset the frequency
converter to factory settings.
WARNING: Before resetting the frequency
converter, make sure that the system is Off,
and that the pump/s are stopped.Once the
reset is done it’s possible to congure the
previous settings only manually setting all
the modied parameters.
To reset the frequency converter it is necessary
change the value of the parameter AP50 from no to
yes, and push the button
(enter).
During this phase the display is turned off for
few seconds, then it will turn off, and it becomes
possible to reprogram the frequency converter.
9. Operating mode programming
9.1. Parameters to check when starting up the unit
i
Check that the motor voltage is matching or
it’s lower than the Mains Supply voltage.
If the motor Voltage is different from 400V set the
parameter SA01 “Nominal Motor Voltage” in order
to match the value written in the motor label.
Once the frequency converter is turned on for the
rst time, after a short check phase on the display
it’s shown Er13.
If the entered rated current value is not
correct there is the risk of pump damage
or to have an unexpected overcurrent
alarmParameter UP03 Nominal pump
frequency
The nominal frequency of the pump must be set.
If the entered rated frequency value entered
is not correct there is the risk of higher
current absorption or pump damage.
If the selected programmed mode is different
from the purpose of the plant there is a risk
of pump damage and/or plant damage.
9.2. Constant pressure operating mode
Constant pressure operating mode keeps constant
the pressure at a point of the system.
In this operating mode the frequency converter
keeps constant the pressure at a set-point value
decided by the user through parameter UP06.
It is possible to have different congurations of this
operating mode related with the different types and
number of transducers installed:
- Constant pressure with 1 pressure transducer
(absolute or differential transducer)
- Constant pressure with 2 pressure transducers
in differential mode.
For detailed program settings see the following
conguration sections.
9.2.1. Constant pressure mode with single
transducer (absolute or differential)
This conguration uses a feedback given by a
pressure transducer (connected as shown in
section 6.7).
Parameters to programm or check (recommended
sequence):
