During the procedure the [+] and [-] keys are used to set the various values. The [MODE] key is used to accept the set
value and move on to the next step. If the mode key is held down for more than 1s, the wizard returns to the previous
page.
5.2.1 Setting the language LA
Select the menu language that you want to use. See par. 6.2.6
5.2.2 Setting the measurement system MS
Set the display system of the measurement unit you want to use for the values on the display. See par. 6.5.9
5.2.3 Setting the pressure setpoint SP
Set the system pressure setpoint value. See par. 6.3.1
5.2.4 Setting the rated frequency of the pump FN
Select the rated frequency of the electropump that you want to use. The wizard measures the mains frequency
entering the inverter and, based on this, proposes a value for FN. The user must set this value according to the
recommendation of the electropump manufacturer. See par. 6.5.3
An incorrect configuration of the working frequency of the electropump may cause damage to the
electropump and give rise to "OC" and "OF" errors.
5.2.5 Setting the rated voltage of the pump UN
This parameter is present only on type M/M inverters, size 11 and 14 A.
Select the rated voltage of the electropump that you want to use. The wizard measures the mains voltage entering the
inverter and, based on this, proposes a value for UN. The user must set this value according to the recommendation
of the electropump manufacturer. See par. 6.5.4
5.2.6 Setting the rated current RC
Select the rated current value of the electropump that you want to use. See par. 6.5.1
An incorrect setting of RC can give rise to "OC" and "OF" errors and cause failed intervention of the
overload protection, allowing a load beyond the safety threshold of the motor and causing damage to
the motor.
5.2.7 Setting the direction of rotation RT
This parameter is present in all sizes of type M/T and T/T inverters.
When you come to the RT setting you must start the pump and check that its axis is turning in the correct direction.
In this phase the RUN/STOP key is used to start and stop the pump. Pressing the key the first time starts the pump,
the second time stops it. During this phase a maximum run time of 2 min is allowed, after which time it switches off
automatically (similar to stopping with the RUN/STOP key).
During this phase the + and – keys allow you to invert the direction of rotation of the motor.
In case of a surface pump with visible direction of rotation:
start the pump,
check the direction of rotation and change it if necessary,
stop the pump,
press mode to confirm the settings made and to start the application.
In case of a submerged pump:
switch on a utility (do not change the utility until the end of the procedure),
start the pump,
make a note of the direction of rotation used and the frequency realised (parameter FR at top right of the
wizard screen 6/6),
change the direction of rotation,
make a note of the direction of rotation used and the frequency realised (parameter FR at top right of the
wizard screen 6/6),
close the utility,
evaluate the two cases examined and set the direction of rotation that gives the lower frequency FR,
press mode to confirm the settings made and to start normal operation.
5.2.8 Setting other parameters
After the initial start-up procedure, the other pre-set parameters can be modified as required, by accessing the
relative menus and following the instructions for the specific parameters (see chapter 6). The most common
parameters are: restart pressure, regulation gain values GI and GP, minimum frequency FL, water failure time TB,
etc.
