5. ELECTRICAL CONNECTIONS OF THE ACTIVE DRIVER TO THE ELECTROPUMP
5.1
Ensure that all the terminals are fully tightened, paying particular attention to the earth
terminal .
5.2 Check that all the connecting cables are in excellent conditions, with the external sheathing
unbroken.
5.3 The motor of the installed electropump must comply with the data in the table in Chapter 4.
The user connected to the ACTIVE DRIVER M/M 1.1 must not exceed 8,5 A as phase current.
The user connected to the ACTIVE DRIVER M/T 1.0 must not exceed 4,7 A as phase current.
The user connected to the ACTIVE DRIVER M/T 2.2 must not exceed 9,3 A as phase current.
The user connected to the ACTIVE DRIVER T/T 3.0 must not exceed 7,5 A as phase current.
The user connected to the ACTIVE DRIVER T/T 5.5 must not exceed 13,3 A as phase current.
5.4 Connect the electropump to the output cable of the ACTIVE DRIVER, paying particular attention to
the earth connection.
The incorrect connection of the earth lines to a terminal other than the earth terminal
may cause irremediable damage to the whole appliance!
The incorrect connection of the power supply line on output terminals intended for the
load may cause irremediable damage to the whole appliance!
6. CONNECTION TO THE POWER SUPPLY LINE
6.1 Connect the ACTIVE DRIVER to the power supply line by means of the power socket.
(See values in chapter 4).
6.2 If an extension to the power cable is used the following minimum sections must be respected:
Section of each lead (mm²) Maximum length of the line (metres)
1.5 15
2.5 30
4 60

ENGLISH
27
6.3 The ACTIVE DRIVER is already provided with current protections. If a magnetothermal switch is
installed in line, it must have a max. capacity of 16A.
6.4 The connection of the line to the ACTIVE DRIVER must include the earth line. The total earth
resistance must not exceed 100 Ohm.
6.5 To protect the system it is recommended to install a differential switch with correct
dimensions, type:
Class A, with adjustable dispersion current, selective, protected against sudden
tripping.
The automatic differential switch must be marked with the following two symbols:
7. HYDRAULIC CONNECTIONS
7.1 Always install a check valve on the pipe upstream from the ACTIVE DRIVER.
For the purposes of operation of the ACTIVE DRIVER it does not matter whether the valve is fitted
on the suction or on the delivery of the pump.
7.2 The hydraulic connection between the ACTIVE DRIVER and the electropump must not have any
derivations.The dimensions of the pipe must be suitable for the electropump installed.
7.3
The ACTIVE DRIVER works at constant pressure. This regulation is appreciated if the hydraulic
system downstream from the system is of suitable dimensions.
Systems made with pipes that have too narrow a section introduce load losses which the appliance
cannot compensate; the result is that the pressure is constant on the device but not on the user.
When electrical and hydraulic installation have been completed, supply power to the system and check the
direction of rotation of the electropump. If it is not correct, invert two phases on the motor terminal board.
8. CHARACTERISTICS – INTERPRETATIONS – OPERATION
The ACTIVE DRIVER is an innovative integrated system for controlling electropumps with variable speed, able to
keep a constant pressure while the flow rate varies.
The ACTIVE DRIVER is composed of an inverter, a pressure sensor and a flow sensor.
With the exclusion of models M/M 1.1 and M/T 1.0 the ACTIVE DRIVER is provided with 3 inputs and 2 outputs so
as to be able to realise certain interface solutions with more complex installations.
Figure 1 shows the logical function diagram for the connection of the user input terminals.

8.3 OPERATION : PARAMETERS FOR THE USER
Access keys MODE & SET for 2 seconds
8.3.1 SP : Setting the set point pressure ( in bar )
From normal operating status, hold down the MODE and SET keys simultaneously until the letters
SP appear on the display. In these conditions the + and – keys allow you respectively to increase and
decrease the desired pressure value.
The regulating range is from 1.0 to 6.0 bar for the A.D. M/M 1.1 and from 1.0 to 9.0 bar for the other models.
Press SET to return to normal operating status.
As well as the working pressure the ACTIVE DRIVER allows you to set two other values:
RP: expresses in bars the decrease in pressure, with respect to SP, that makes the pump restart.
DP: expresses in bars the desired decrease in pressure at low flow rates.
The three parameters are related to each other.
Diagram for regulating pressure according to in flow rate
SP
Example:
SP = 4.5 bar
DP = 1.0 bar
RP = 0.7 bar Q
During normal operation the system will be pressurised at 4.5 bar.
In case of low flow rates (losses) the system will be pressurised at 3.5 bar.
The electropump restarts when the pressure falls below 2.8 bar.
8.4 OPERATION : PARAMETERS FOR THE INSTALLER
Access keys MODE & SET & - for 5 seconds
If an error or malfunction occurs during this phase, the display is not changed. Depending on
the type of error, the electropump may switch off. However it is still possible to make the
desired calibration. To know the type of error that has occurred you must return to the mode
in which you see the operating status by pressing the SET key.
From normal operating status, hold down the MODE & SET & - keys simultaneously until the letters “rC”
appear on the display. In these conditions the + and – keys allow you respectively to increase and decrease
the value of the parameter while the MODE key allows you to move on to the next parameter in cyclic mode.
Press SET to return to normal operating status.
8.4.1 rC : Setting the rated current of the electropump (excluding A.D. M/M 1.1)
This parameter must be set the same as the current on the motor data plate (Amps) in the configuration
in which it is used (power supply 230V for A.D. M/T - power supply 400V for A.D. T/T).
8.4.2 rt : Setting the direction of rotation (excluding A.D. M/M 1.1)
Possible values: 0 and 1
If the direction of rotation of the electropump is not correct, it is possible to invert the direction of
rotation by changing this parameter.
If it is not possible to observe the direction of rotation of the motor, proceed as follows:
- Open a user and observe the frequency (parameter Fr with MODE key from GO) and the current
(parameter C1).
- Without changing the amount of water taken, change the parameter rt and observe the frequency Fr
and the current C1 again.
- The correct parameter rt is the one which, with the same amount of water taken, requires a lower
frequency Fr and current C1.

8.4.3 od: Setting the operating mode of the ACTIVE DRIVER
Possible values: 1 and 2
The ACTIVE DRIVER leaves the factory in mode 1 for working without expansion vessels or with
small vessels. If there is an expansion vessel near the ACTIVE DRIVER, with a half-inch or larger
fitting, you must change to mode 2.
8.4.4 rP: Setting the fall in pressure for restarting
Expresses, in bars, the fall in pressure that makes the pump restart.
rP may be set from a minimum of 0.1 to a maximum of 1.5 bar.
rP has a limitation system depending on the combination of the values SP and dP so that there is always
a minimum restarting pressure of 0.3 bar.
8.4.5 Ad : Setting the interconnection address (excluding A.D. M/M 1.1)
With the ACTIVE DRIVER system it is possible to realise booster sets composed of two elements
communicating by means of serial interconnection (see fig.3). In this type of installation it is necessary
for the two units to have a different identifying address (Ad).
The admissible values are: “- -”, 1 and 2:
- When “Ad” is “- -” the communication is disabled.
- When “Ad” is “1” it is called Secondary ACTIVE DRIVER (booster).
- When “Ad” is “2” it is called Primary ACTIVE DRIVER (leader).
Attention: If two interconnected ACTIVE DRIVER units are set with the same “Ad” value, the
communication does not work and there may be malfunctions in regulation.
When the communication does not work (due to incorrect setting of the “Ad” value, for wiring
problems, or other reasons), the two ACTIVE DRIVER units will work as though they were two
completely independent machines, but they will indicate the impossibility of dialogue by making the
display blink when the states “Go” or “Sb” are shown.
When the “Ad” values are correctly set, some regulating parameters are aligned. In particular the
secondary ACTIVE DRIVER copies the following values from the primary ACTIVE DRIVER:
- SP : Setting of the set point pressure.
- rP : Setting of the restarting pressure drop.
- Eb : Enabling of the booster pump.
- CM : Method of exchange.
- dP : Setting of the pressure differential at low flow rates.
- P1 : Setting of the input function 2 set point P1.
Note: During operation it is possible to change all the parameters of the ACTIVE DRIVER on each of
the two machines.
8.4.6 Eb : Enable booster (pre-set value 2) (excluding A.D. M/M 1.1)
When two ACTIVE DRIVER units are interconnected with each other, in the case where only one
ACTIVE DRIVER is not able to satisfy the user, there is the possibility of activating the two
electropumps at the same time.
Eb = 1 : The leader-booster operating mode is disabled, so only one electropump at a time will
be active.
If during operation the leader electropump is not able to satisfy the user, the booster
electropump will not be switched on.
Eb = 2 : The leader-booster operating mode is enabled, so 2 electropumps can be activated at the
same time.
If during operation the leader electropump is not able to satisfy the user, the booster
electropump will also be switched on and will work at the maximum frequency, while
the leader machine will continue to modulate the rotation frequency according to the
user.

8.5 OPERATION : TECHNICAL ASSISTANCE DISPLAYS AND SETTINGS
Access keys MODE & SET & + for 5 seconds
8.5.1 tb: Setting the reaction time of the water lack blockage
The setting of the reaction time of the water lack blockage allows you to select the time (in seconds)
taken by the ACTIVE DRIVER system to indicate the lack of water in the electropump. The variation
of this parameter may be useful if it is known that there is a delay between the moment in which the
electropump is switched on and the moment in which it actually starts delivering.
8.5.2 GP: Setting the gain of the proportional coefficient of the PI
For nearly all systems, the GP parameter set in the factory is the optimum one. However, if there
should be any problems in regulation, this setting may be adjusted. Indicatively it may be said that, for
example, the presence of great swings in pressure or of a slow response of the system to variations in
pressure may be compensated by high GP values. Instead the occurrence of “vibrations” in pressure
(extremely rapid pressure swings around the set point value) may be attributed to too high a GP value.
8.5.3 GI: Setting the gain of the integral coefficient of the PI
The integral value must be increased when the system is not very elastic, that is where there is absence
of any expansion. On the contrary, in systems with deformable pipes or with delays due to considerable
distances between the electropump and the ACTIVE DRIVER, the integral value must be lowered.
To obtain satisfactory pressure regulations, you generally have to adjust both GP and GI. In
fact it is the correct agreement between these two parameters which allows the optimum
pressure regulation.
8.5.4 FS: Setting the maximum rotation frequency of the electropump
The ACTIVE DRIVER allows the electropump to be fed for short periods at a frequency higher than
the rated one, returning then to 50 Hz without heating the motor.
When increasing the power supply frequency take care not to exceed the max. current of 9.3
A, otherwise there is a risk of blockage due to current overload in the power stages oF.
8.5.5 dP: Setting the pressure differential at low flow rates
In mode od=01, the setting of the allowed excursion for the pressure set point permits you to select a
pressure interval lower than the set point (SP) at which the ACTIVE DRIVER will regulate the
pressure in the event of low flow rates.
The advantage of selecting a dP different from zero lies in the redimensioning of the flow rate if there
are losses n the system and allows an energy saving so that the electropump can be operated at low
speeds when the requested flow rates are low.
To select the possible dP values, the ACTIVE DRIVER is equipped with a limiting system which
intervenes when pressure set points lower than 2.0 bar are set. In this case the dP is limited to 0.5. See
example on page 29.
8.5.6 Ft: Setting the low flow rate threshold
The ACTIVE DRIVER system possesses a flow sensor. Whenever the electropump is switched off a
new zero is acquired. The ACTIVE DRIVER switches off the electropump when the flow rate reading
is lower than 0 flow (ZF) + the set Ft parameter.
8.5.7 CM : Method of exchange (pre-set value 1) (excluding A.D. M/M 1.1)
When two ACTIVE DRIVER units are interconnected to work in exchange it is possible to choose
between two different strategies for alternating the switching on of the two electropumps.
CM = 0 : The primary ACTIVE DRIVER is always the regulation leader and the secondary
ACTIVE DRIVER will be active as a booster (if Eb=2) or as a reserve (if Eb=1). If the
secondary machine remains unused for 23 hours, it becomes the leader until it has
accumulated one minute of regulation.
If during operation the leader electropump is unable to satisfy the user and the
secondary electropump is set as a booster (Eb=2), the latter will work at maximum
frequency, while the leader ACTIVE DRIVER will continue to modulate the rotation
frequency according to the user.
If the user decreases, the booster machine is switched off, while the leader machine
continues regulating.

CM = 1 : The primary and secondary ACTIVE DRIVER alternate in being the regulation leader.
The exchange takes place each time the leader ACTIVE DRIVER goes into stand-by
mode or after 2 hours of continuous activity.
If during operation the leader electropump is unable to satisfy the user and the
secondary electropump is set as a booster (Eb=2), the latter will work at maximum
frequency, while the leader ACTIVE DRIVER will continue to modulate the rotation
frequency according to the user.
If the user decreases, the leader machine goes into stand-by and becomes the booster
(off), while the booster machine becomes the leader (and starts regulating at variable
speed).
For each of the two exchange modes, if one of the machine breaks down, the other becomes the leader
and carries out regulation at constant pressure up to its maximum available power.
8.5.8 AE : Enabling the anti-frost function (pre-set value 1)
Starts rotating the motor-impeller assembly in order to avoid mechanical blockages.
When the anti-frost function is enabled, if the ACTIVE DRIVER measures a temperature that is too
low with a risk of frost, it automatically starts running the electropump at a low number of revs (25
Hz).
8.5.9 Setup of the auxiliary digital inputs IN1; IN2; IN3 with the parameters i1; i2; i3
(excluding A.D. M/M 1.1 and A.D. M/T 1.0)
The function assigned to each of the digital inputs IN1; IN2; IN3 may be activated or modified by
means of the parameters i1; i2; i3.
The setup of the parameters i1,i2,i3 may always assume the values:
0 => function disabled
1 - 3 - 5 => function active on high active input tied to the supply voltage + 12V(see fig. 1)
2 - 4 => function active on low active input tied to GND 0V (see fig. 1)

following values are displayed:
( NB: to scroll through the values press the MODE key)
UF: Display of the flow
Display of the instantaneous flow.
Parameter to be used only as a reference in programming.
ZF: Display of zero flow
Display of the reading of the flow sensor on which zero was acquired (with electropump switched off).
During normal operation the ACTIVE DRIVER will use this parameter to switch off the electropump.
FM: Display of the maximum rotation frequency (in Hz)
tE: Display of the temperature of the power stages (in °C)
GS: Display of running status
SP = pump operating to maintain pressure “SP”.
P1 = pump operating to maintain pressure “P1” (input 2 active).
AG = pump operating for “anti-frost”.
FF: Display of fault history (+ & - to scroll through the alarms)
There is a queue of 16 positions for containing the last 16 faults which have occurred during system
operation. By pressing the – key you can go back in history and stop at the oldest fault present, whereas
by pressing the + key you can go forward in history and stop at the most recent fault present.
The decimal point identifies the last fault to have occurred in chronological order.
The history contains at the most 16 positions. Each new fault is inserted in the most recent position
(decimal point). For each fault after the sixteenth, the oldest one in the queue is erased. The history of
the faults is never erased but only updated as new faults occur. Manual reset and switching off of the
appliance do not erase the history of faults.
10. ACCESS

MODE & SET & + & -
12. RESTORING THE FACTORY SETTINGS
Access keys SET & + for 2 seconds when switching on
The factory settings are indicated in table no. 14 on page 36.
To reset the factory values:
Switch off the appliance, press and hold down the SET and + keys while switching on the appliance again, release
the two keys only when the letters EE appear. In this case the ACTIVE DRIVER restores the factory settings.
When it has finished setting all the parameters the ACTIVE DRIVER returns to normal operation.
In this phase, in the models in which RC is active, the motor current is set at 0 as factory
default, so when you try to start the electropump it will immediately give the error EC.
Go to the installer’s display and settings menu (keys MODE & SET & - for 5 seconds ) and
set the correct motor data plate current (parameter rC as in paragraph 8.4.1.)
13. ERROR AND STATUS CONDITIONS
The ACTIVE DRIVER is equipped with a protection system against malfunctions. If any malfunctions
occur, this is indicated on the display and, depending on the type of error, the electropump may switch
off.
In cases of blockage due to water lack (bL), blockage due to current overload in the electropump (oC),
blockage due to current overload in the output stages (oF), blockage due to direct short circuit between the
phases of the output terminal (SC) and of low line (LL) indication, you may try to exit the error conditions
by pressing the “+” and “–” keys simultaneously. If the error condition remains, you must take steps to
eliminate the cause of the malfunction. Error conditions

13.1 “bL” Blockage due to water lack
In conditions of zero flow the system switches off the pump. If, by mistake, a pressure set-point is set
which is higher than the maximum pressure that the electropump can supply, the system indicates
“blockage due to water lack” (bL) even if there is really no lack of water. Then you must lower the
switch-off pressure to a reasonable value that normally does not exceed 2/3 of the head of the installed
electropump.
13.2 “LP” Blockage due to low supply voltage (excluding A.D. M/M 1.1 and A.D. M/T 1.0)
When the line voltage at the supply terminal falls below 180V, the ACTIVE DRIVER goes into block
status due to low line voltage. This is reset only automatically when the voltage at the terminal rises
above 200V.
If the dimensions of the wiring are not suitably large, this block may occur when the electropump is
started even if higher voltages are measured with the machine in stand-by mode.
13.3 “LL” Blockage due to low supply line (excluding A.D. M/M 1.1 and A.D. M/T 1.0)
This indication is given when more than 5 falls in the supply voltage (LP) are recorded in the space of
an hour. However the appliance continues operating regularly. Repeated switch-offs of the appliance do
not cause the appearance of the “LL” signal.
If the signal “Low line voltage” (LL) is given, the system does not block and the normal indications of
operating status or error continue to alternate on the display.
The ACTIVE DRIVER is equipped with an electronic protection for current overloads in the
electropump motors.
13.4 “SC” Blockage due to direct short circuit between the phases of the output terminal
The ACTIVE DRIVER is equipped with protection against the direct short circuit which may occur
between the phases U, V, W of the “PUMP” output terminal. When this block status is indicated, you
are advised to eliminate the short circuit and to check the wiring carefully to ensure it is unbroken and
the installation in general. Once these checks have been made you can try to reset operation by
simultaneously pressing the “+” and “–” keys; anyway, this will have no effect until 10 seconds have
passed from the moment in which the short circuit occurred.
Whenever a short circuit occurs, an event counter is increased and saved in the permanent memory
(EEPROM).
AFTER THE HUNDREDTH SHORT CIRCUIT THE MACHINE BLOCKS PERMANENTLY
AND IT WILL NO LONGER BE POSSIBLE TO UNBLOCK IT!
13.5 MANUAL RESET of error condition
In error status the operator can reset the error by forcing a new attempt, pressing the “+” and “-” keys
simultaneously.
13.6 Self-reset of error conditions
For some malfunctions and block conditions, the system makes attempts at automatic reset of the
electropump.
The following table shows the sequences of the operations performed by the ACTIVE DRIVER for the
different types of blockage.
Automatic resets of error conditions
Display indication Description Sequence of automatic reset
bL Blockage due to water lack
- An attempt every 10 minutes for a total of 6 attempts
- An attempt every 1 hour for a total of 24 attempts
- An attempt every 24 hours for a total of 30 attempts
LP Blockage due to low supply
voltage
- Reset when voltage returns to a value in the range
