8.2 Initial configuration
When VASCO Solar is switched on for the first time, the initial setting menu is displayed for the initial setting of parameters
to configure pump and system characteristics.
If the initial setting procedure is not completed properly, it is impossible to run the pump. Initial setting procedure can be
repeated if necessary.
The initial setting procedure can be repeated (by using the 2
rd
level password) to reconfigure VASCO Solar or if VASCO Solar is
installed in a different system.
A brief description of parameters and their allowable ranges are listed below:
Parameter

Description
XXXX
End user communication language
XXX
Open circuit voltage of PV strings. Please refer to PV panels
datasheet.
XXX
Motor rated voltage (as shown in the motor plate)
Average voltage drop due to the inverter is between 20 V and 30
Vrms based on load condition.
XX
Rated current of the motor per it’s nameplate indication increased by
10%. The voltage drop caused by the inverter leads to higher input
current than nominal. Make sure motor is capable of accepting
increased current.
50
Rated frequency of the motor per its nameplate.
Control mode: MPPT
Press START/STOP to run a test at rated frequency
Warning: make sure to run the system without damaging pump and
system
--->
If, during the test, the motor runs in reverse, it is possible to change
the wiring sequence via software without physically changing wires at
the terminals.
OFF
If ON is selected, after a lack of voltage, VASCO Solar returns to its
normal status; if VASCO Solar was powering the pump before the
voltage drop, it resumes powering the pump automatically.
Warning, review the advice in chapter 1
Once the Setting procedure is completed you will get this indication
on the display; setting parameters are recorded by VASCO Solar;
these parameters can be set up individually in the INSTALLER
Parameters menu or ADVANCED Parameters menu.
