WARNINGS
• Please read all parts of this manual carefully before installing and using the product.
• Check that the rating plate data is as required and matches the facilities.
• Only qualied personnel capable of making electrical connections in accordance with national regulations may carry out
installation and maintenance.
• TheVSP must only be used for the purpose and operation for which it was designed. Any other application and use should
be considered misuse and hazardous.
• In the event of a re at or near the installation site, do not use water jets, but use suitable extinguishers (powder, foam,
carbon dioxide).
• Install the equipment away from heat sources in a dry, covered place in accordance with the specied degree of protection
(IP).
• Only qualied technicians who are aware of the safety regulations in force may carry out any installation and/or mainte-
nance work.
• Use of non-original spare parts, tampering or improper use will void the product warranty.
• The manufacturer cannot be held liable for damage deriving from misuse of the product and is not responsible for damage
caused by maintenance or repairs carried out by unqualied people and/or using non-original spare parts.
DURING THE FIRST INSTALLATION PHASE AND IN THE EVENT OF MAINTENANCE, ensure that:
• THERE IS NO LIVEVOLTAGE on the electricity mains.
• The system IS NOT PRESSURISED
• The electrical power mains is equipped with safety devices and, in particular, a high sensitivity dierential switch (30
mA in class F and B) suitable to protect against fault currents, alternating type, unipolar button, continuous with high
frequency. Also check that the earthing complies with the regulations.
• Before removing the cover of the inverter or starting interventions on it, disconnect the system from the electrical mains
at least 5 minutes so that the capacitors have the time to discharge using the built-in discharge capacitors;
• Having carried out the electrical connection on the system, check the settings of the inverter.
• Do not remove the cover and/or disconnect theVSP power if the inverter is running.
ATTENTION: If out of services (display on in OFF with white background) VSP remains live; before any
intervention, it is compulsory to disconnect power from the unit.
EMERGENCY STOP
WhileVSP is running, you can make an emergency stop by disconnecting the power supply to the unit.
Ensure there is no VOLTAGE on the electricity mains. Make sure that the system is NOT PRESSURISED.

POSITIONING OF THE PRODUCT
• Fasten the unit to a horizontal surface with screws.
• If the pump must be installed outside where frost can occur, protect it to avoid freezing.
For correct operation of the VSP, installation is indispensable of an adequate expansion tank .
• The expansion tank:
– Accumulates pressurised water to reduce pump start-up to a minimum.
– It is indispensable in the presence of small system leaks.
– It absorbs any excess pressure from the system.
–The minimum volume necessary, in litres (for membrane models) is approximately equal to 10% of the maximum ow
rate of the individual pump, expressed in l/min.
Example of standard application: Qmax = 80 l/min àV = 80 x 10% = 8 litres (rounded in excess to commercial size).
– Pre-load pressure (with system empty): 70% approx. of working pressure:
Example: Pset = 4 bar àPreload pressure = 4 x 70% = 2.8 bar.
• Correctly connect the pressure sensor supplied to the system (see next chapter).
PRESSURE SENSOR
A pressure sensor is a transducer that measures the pressure of a liquid or a gas, using an electric signal sent to a receiver in
analogue format. The pressure sensors are then also called pressure transducers.
The working principle is based on the physical deformation of the strain gauge in the transducer membrane: the electrical
resistance is proportional to the pressure applied, which is converted to an electric signal, the output is transmitted in cur-
rent that varies from 4 to 20 milliampere.
The pressure sensor should be positioned on the system as indicated in the gures on the previous page.

8| VSP
ELECTRICAL CONNECTION
Make sure that there is no voltage at the terminals of the line conductors before making the connec-
tions. Also ensure the electrical power supply mains is equipped with safety devices and in particular a
high sensitivity dierential switch (30 mA, in class F or B) and a ground compliant with standards.
• Check the electricity mains power supply voltage corresponds to the voltage indicated in the VSP inverter plate
and the motor, therefore connect the ground before every other connection.
• The voltage of the VSP power line can vary in a range between +/-10% of the plate power voltage.
• Check the rated current absorbed by theVSP unit is compatible with the plate data.
• The power line must be protected by a dierential circuit breaker switch, with the characteristics listed above.
• Secure the electrical cables in the corresponding terminals using a tool of suitable size to avoid damaging the clamping
screws. Take extra care when using an electric screwdriver.
• Do not use multicore cables containing both conductors connected to inductive power loads and signal conductors such
as sensors and digital inputs.
• Make connection cables as short as possible, and avoid forming them into a spiral shape as inductive eects could damage
the electronics.
• All wiring conductors must be suitably dimensioned to withstand the loads they supply.
• The electrical wiring between the electric pump and the inverter is carried out in the factory and therefore for operation
no operation is necessary.

START-UP
PUMP PRIMING
• Before start-up, fully read this manual and follow the instructions, to avoid wrong settings and manoeuvres that could
cause operating faults.
• Do not start the electric pump dry, unless for a few seconds.
• Before starting the VSP, ll the pump (priming).
• Insert the power plug in the socket.
• Wait the STARTING time (approx. 10 seconds).
• Once 10 seconds are up and the STARTING phase has terminated, the VSP returns to the same operating conditions it was
in on last plug insertion.
– IN SERVICE if at time of last switch o it was IN SERVICE.
– OUT OF SERVICE if at time of last switch o it was OUT OF SERVICE.
In the event of accidental contact of the voltage, ifVSP was IN SERVICE (ON), on resetting the mains, it returns IN SERVICE
(ON).

12 | VSP
• To put the VSP in service, press the ON/OFF key on the control panel.
• Having pressed the ON/OFF key ensure the pressure of the system is under the SETPOINT value less the RESTART
DIFFERENTIAL set. Only in this condition can the inverter start the electric pump.
• If the electric pump is not correctly primed, bringVSP toTEST mode (manual operation) and gradually open the supply
valve (for operation inTEST mode, see the corresponding chapter described later in the following manual).
ATTENTION: the inverter is perfectly congured by default settings, to work correctly with the associated elec-
tric pump.
If theVSP default values should be edited, set the inverter using the parameters in the ADVANCED MENU (see the ADVANCED
MENU PARAMETERS chapter)
After making all the electrical and plumbing connections correctly, enter the conguration menu to set the correct parame-
ter values for the kind of operation to be performed by the system.
FUNCTIONING PARAMETERS
• The display on the control panel assumes three dierent types of colours based on the status in which theVSP is found.
–WHITE display if theVSP is found in STAND BY
– GREEN display if theVSP is working regularly (START)
– RED display if theVSP is in alarm mode due to some fault (ERROR)
–YELLOW display if theVSP is found in the PROGRAMMING MENU
• WhenVSP is regularly working, the display on the control panel turns GREEN and on the display:
– the automatic operating indicators lights turn on and electric pump running ;
– the alphanumerical display will show the system pressure.
– the fountain logo indicator lights start to run;
• IfVSP sets to alarm mode, the display on the control panel will turn RED and the display switches on the indicator and
the alphanumerical display will show an ERROR and the alarm type.

• Sets the minimum operating frequency.
Default 30 Hz Range 25-70 Hz Step 1 Hz
MOTOR CONFIG
F MAX 50 MAXIMUM FREQUENCY
• Sets the maximum operating frequency. ATTENTION: increase in max-
imum frequency compared to the rated frequency can cause strong
motor overloads.

MOTOR CONFIG
COSFI MIN 0,50 MINIMUM COSFI FOR DRY RUN
• Sets the minimum value of the cos under which the dry run is de-
tected
Default 0.50 Range 0.1–1 Step 0.01
MOTOR CONFIG
COSFI TIME 10 STOP DELAY FOR DRY
• Sets the pump stoppage delay in the dry run condition.
(0=Dry0=dry run disabled)
Default 0 sec Range 0–100 sec Step 1 sec
(*) The DEFAULT value depends on the electric pump model associated with the VSP inverter
