1. Introduction
We strongly suggest that the operator carefully
reads and follows the information contained in
this instruction manual for the frequency
converter.
Symbol used:
This symbol indicates high voltage
hazard. It draws attention to components
or procedures that could represent a
potential danger to the health and welfare
of the operator.
This symbol is used to draw the operator's
attention to situations of potential danger
for people or for operations that could
cause damage to the product.
2. Special warnings regarding
the frequency converter
We strongly suggest that the operator
carefully reads and follows the information
contained in this instruction manual for the
frequency converter.
The FREQUENCY CONVERTER should
NEVER be opened or tampered with
and guards that come with it should
never be removed.
The frequency converter must be
installed, adjusted and maintained by
qualified personnel who understand the
risks involved.
The frequency converter must be fitted
with voltage surge and overload
protection devices, in accordance with the
prevailing safety standards.
The connection of the alarms can
distribute power even when the frequency
converter is turned off. Ensure that there
is no residual voltage on the terminals of
the alarms.
All the power terminals and other
terminals must be inaccessible after
installation is completed.
The maximum output frequency must not
exceed the design frequency of the pump
being controlled. Operating at a frequency
higher than the allowable frequency can
cause higher current absorption and
damage to the device.
If it is necessary to remove the frequency
converter, remove only the covers
required in order to disconnect the
electrical cables. Take care not to damage
the electronic cards.
Failure to comply with the safety
regulations not only causes risk to
personal safety and damage to the
equipment, but also invalidates every right
to assistance under warranty.
Electro-magnetic compatibility.
The frequency converter is constructed in
compliance with European standard 2004/108CE.

8. Dry-running protection
The frequency converter is equipped with a dry-
running protection for the pumps. When the
pressure on the system remain for a time higher
than the dry-run time (AP05) lower than value of
the dry-run pressure (AP07) the protection system
stop the pump. It is possible the use of an external
float switch for the dry-running protection (see
paragraph 7.5.). In this case the pumps start with
a delay time (in seconds) defined by AP19 (Digital
input restart time), the time will be counted after
the change of the float switch state.

to be checked when the unit is started up:
• arameter U 02 NOMINAL UM CURRENT
The nominal current of the pump must be set.
If the value input is inappropriate there is
the risk of pump damage or to have an
unexpected overcurrent alarm.
• arameter U 03 NOMINAL UM
FREQUENCY
The nominal frequency of the pump must be set.
If the value input is inappropriate there is
the risk of higher current absorption or
pump damage.
• arameter U 05 SET OINT RESSURE
The working pressure of the pump must be set.
If the value input is inappropriate for the needs
of the system, the value can be increased or
decreased using the (plus) or (minus)
keys.
If during the first start-up of the unit, filling
the system takes longer than 1 minute and
the unit signals a dry-running alarm,
Increase the parameter AP06, until the
pressure rises above the set value and the
pump remain on. (Make sure the pump
are primed).
11.1. Vessel pressure
Once the new working pressure is entered,
the tank pre-loaded pressure must be
changed to be 2/3 of the working pressure
(i.e. 4 bar working pressure,tanks to be
pre-loaded at 2.7 bar).

12. Plant starting
ATTENTION: never run the pump dry
not even for a short trial run. Start the
pump after filling completely with liquid.
After completing hydraulic and electrical
connection and checked the preloaded pressure
(for booster set with membrane tank), start the
plant as indicated below:
Prime the pumps (see the pumps instructions).
ump with suction lift:
- Fill the suction pipe and the pump body by
means of the plug hole located close to the
delivery port of the pump.
- Fill the suction tube by pouring water through
the plug hole on the suction manifold of the
pump.
ump with positive suction head:
- Open the gate-valve in the suction
pipeline.With sufficient head, the water will
overcome the resistance of the non-return
valve fitted in the suction side of the pump and
will fill the pump body. Otherwise, prime the
pump with the plug hole near the delivery port.
Never run the pump or more than ive
minutes with closed gate valve.
Starting pump
When the freqeuncy converter is switched on, the
pump are not operating and on the screen
appears OFF.
Press the button (play) to change the pump
status from STOP to run. The pump starts up with
the acceleration ramp set to reach the wished
pressure.
When the motor starts turning, check
the direction of rotation.
If the pump has been primed correctly, after a few
seconds the pressure will begin to increase on the
display.
If, after a few seconds‚ operation the pressure
remains at 0.0, stop the pump by selecting
(stop) as priming has not been carried out
correctly and the pump is idling. Re-prime the
pump and repeat the starting up procedure.
12.1. Inversion of the direction
of rotation
To change the direction of rotation of the motor,
push the button (menù) and then with the
button (plus) move up to the programming
parameter UP. Confirm with (enter) and with
the button (plus) move up to the parameter
UP04, confirm with enter (enter) and by
pushing of the button (plus) change the value,
confirm with (enter). To exit the program,
push (menù) until you arrive on the basic
display, when you are out from the set-up mode
the icon disappear .
13. Operations
The frequency converter is programmed to
manage the automatic operation of 1 or 2 pumps,
all at variable speed.
Depending on user consumption, the pumps start
to guarantee the amount of water necessary at
the set pressure.
When one pump has reached 50 z and water
requirements increase, the second pump will
begin operations.
The pumps are protected against:
- operation when dry, by means of a floating
switch and level sensor,
- over/under voltage (frequency converter),
- thermal overload (frequency converter).
13.1. Quick set point modification
If the frequency converter is operating in constant
pressure mode it is possible to change the set
point pressure without enter on the user
parameter (UP menu). Pushing the button
(enter) for more than 5 seconds you will enter
directly to the set point pressure (UP05
parameter).
By pushing of the buttons (plus) or
(minus) change the pressure value and confirm
with (enter).
By pushing of the button (menu) the system will
return to the basic display (see paragraph 9.1.).

14. Use of megaohmeter
Megging of an installation incorporating the
frequency converter is not allowed, because the
electronics may be damaged. If megging is
necessary, disconnect the frequency converter
and use the megaohmeter directly on the terminal
box of the pump.
15. Maintenance
Inspect the tank pre-loaded pressure
of the delivery vessel periodically.
