1. GENERAL
Read this documentation carefully before installation. Installation and functioning must comply
with the safety regulations in force in the country in which the product is installed. The entire
operation must be carried out in a workmanlike manner.
Failure to comply with the safety regulations not only causes risk to personal safety and damage to
the equipment, but invalidates every right to assistance under guarantee.
2. WARNINGS
2.1 Skilled personnel
It is advisable that installation be carried out by competent, skilled personnel in
possession of the technical qualifications required by the specific legislation in force.
The term skilled personnel means persons whose training, experience and instruction, as well as
their knowledge of the respective standards and requirements for accident prevention and working
conditions, have been approved by the person in charge of plant safety, authorizing them to perform
all the necessary activities, during which they are able to recognize and avoid all dangers. (Definition
for technical personnel IEC 60634).
2.2 Safety
Use is allowed only if the electric system is in possession of safety precautions in accordance with the
regulations in force in the country where the product is installed (for Italy, IEC 64/2).
2.3 Responsibility
The Manufacturer does not vouch for correct operation of the ACTIVE DRIVER or for any damage
that it may cause if it has been tampered with, modified and/or run outside the recommended work
range or in contrast with other indications given in this manual. The Manufacturer declines all
responsibility for possible errors in this instructions manual, if due to misprints or errors in copying.
The Manufacturer reserves the right to make any modifications to products that it may consider
necessary or useful, without affecting the essential characteristics.
2.4 PARTICULAR WARNINGS
Before working on the electrical or mechanical part of the system, always turn off the mains voltage.
Wait at least five minutes after the power supply to the machine has been switched off before opening
the appliance. The condenser of the continuous intermediate circuit remains charged with dangerously high
voltage even after the mains voltage has been switched off.
Only firmly wired mains connections are admissible. The appliance must be earthed (IEC 536 class 1, NEC
and other relevant standards).
Mains terminals may carry dangerous voltage even when the motor is stopped.
In determined calibration conditions, after a power cut the converter may start automatically.
Pay attention: the motor terminals U, V and W (for the Active Driver M/M 1.1 the motor terminals R
and S) may carry dangerous voltages even when the converter is not operating.
Do not operate the appliance in direct sunlight.
This appliance may not be used as an “EMERGENCY STOP mechanism” (see EN 60204, 9.2.5.4).

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
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.

ENGLISH
41
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.
7.4 RISK OF FROST: pay attention to the place where the ACTIVE DRIVER is installed!
If the place of installation reaches a temperature below 0°C, the following precautions must be
taken:

If the ACTIVE DRIVER is operative it is absolutely necessary to protect it suitably
against frost and to leave it constantly fed.
If it is disconnected from the power supply, the anti-frost function is no longer active!

If the ACTIVE DRIVER is not operative it is advisable to turn off the power supply,
disconnect the appliance from the pipe and completely empty out all water left inside it.
It is not sufficient just to remove pressure from the pipe, because some water is
always left inside.
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.
Figure 2 shows the logical function diagram for the connection of the alarm output terminals.
Figure 3 shows the connection diagram for 2 ACTIVE DRIVER units, for the exchange function.

When the + key or the – key is pressed, the selected value is modified and saved immediately. Even the
accidental shut-down of the machine during this phase does not cause the loss of the newly set parameter. The
SET key is used only to return to the display of the machine status. It is not fundamental to press the SET key
in order to save the changes made.
8.3 FIRST SWITCH-ON OPERATIONS (only with ACTIVE DRIVER as accessory)
(ref. Table no. 14 page 53)
After having correctly carried out the installation of the hydraulic and electric system, power can be
supplied to the ACTIVE DRIVER.
The letters “ZF” will appear on the display and after a few seconds the error condition “EC” will be
shown.
To start the ACTIVE DRIVER it is necessary to set the current value shown on the data plate (in A) and
the frequency (in Hz) of the electropump used.
Below are described some steps for setting the main parameters and making the first start-up.
8.3.1 Setting the rated current “rC”
In normal operating status, hold down simultaneously the MODE and SET and - keys until "rC" appears on
the display.
Using the + and – keys you can respectively increase and decrease the value of the parameter, according to the
indications on the data plate of the electropump motor.
If the set parameter is lower than the correct one, during operation the error message “oC” will appear as soon
as the set current has been exceeded for a certain time.
If the set parameter is higher than the correct one, the overload protection will trip incorrectly beyond the
motor safety threshold.
An incorrect configuration of the electric motor of the electropump may cause damage to the
motor.
If SET is pressed to leave the menu without setting “Fn”, the set current value is activated but
the ACTIVE DRIVER is not unblocked because the frequency has not been set and the letters
“EC” will still be displayed.
8.3.2 Setting the rated frequency “Fn”
From the parameter “rC”, press the MODE key once, the electropump rated frequency “Fn” will appear
on the display.
The frequency “Fn” must be set as shown on the data plate of the electropump using the + and – keys.
The next time MODE or SET is pressed, the set current and frequency values are activated and the
ACTIVE DRIVER is unblocked, unless other error or blocking conditions have occurred.
An incorrect configuration of the working frequency of the electropump may cause damage to
the electropump.
8.3.3 Setting the direction of rotation
From the parameter “Fn” press the MODE key to make the current and frequency settings active and
move on to the next item “rt”. At this point the ACTIVE DRIVER is ready to start.
Switch on a user to start the electropump turning.
If the direction of rotation is correct, proceed to set the Setpoint pressure, otherwise invert the direction of
rotation of the motor using the + and – keys (function active even with the motor switched on).
8.3.4 Setting the setpoint pressure
In normal operating status, hold down simultaneously the MODE and SET keys until "SP" appears on the
display. In these conditions the + and – keys respectively allow you to increase and decrease the desired
pressure value.
The regulating range is from 1 to 15 bar depending on the ACTIVE DRIVER model.
Press SET to return to normal operating status.

ENGLISH
45
8.4 OPERATION : PARAMETERS FOR THE USER (ref. Table no. 14 page 53)
Access keys MODE and SET for 2 seconds
8.4.1 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 to 6 bar for the S.D. M/M 1.1, from 1 to 9 bar for the A.D. M/T 1.0 and
from 1 to 15 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 one other value:
rP: expresses in bars the decrease in pressure, with respect to SP, that makes the pump restart.
8.5 OPERATION : PARAMETERS FOR THE INSTALLER (ref. Table no. 14 pa
g
e 53)
Access keys MODE and SET and – 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 and SET and –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
.
8.5.1 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).
8.5.2 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.
8.5.3 Fn : Setting the rated frequency (pre-set value 50Hz)
This parameter defines the rated frequency of the electropump and it may be set at 50Hz or 60Hz.
However the frequency must be set as indicated on the data plate of the
electropump motor.
Press the + or – keys to select the two frequencies 50Hz or 60Hz.
An incorrect setting of the rated frequency may cause damage to the
electropump.
Each change of Fn is interpreted as a change of system and so FS, FL and FP will automatically assume
the default values.
8.5.4 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.

ENGLISH
46
8.5.5 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 is equipped with a limiting system depending on the combination of the SP value so as to have in any
case a minimum restarting pressure of 0.3 bar.
8.5.6 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.
8.5.7 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.
8.6 OPERATION : TECHNICAL ASSISTANCE DISPLAYS AND SETTINGS
Access keys MODE and SET and + for 5 seconds (ref.Table no. 14 pa
g
e 53
)
8.6.1 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.
8.6.2 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.

ENGLISH
47
8.6.3 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.
8.6.4 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 frequency, limiting the maximum frequency sent to the electropump in the event of an excessive
increase in temperature.
The value of the set maximum frequency (FS) can therefore be reached with the motor cold and it
decreases to Fn (rated frequency) as the temperature rises in the windings.
The ACTIVE DRIVER also allows a maximum working frequency to be set that is lower than the rated
frequency Fn. In this case, in whatever regulating condition, the electropump will never be run at a
frequency higher than the set rated frequency.
The maximum FS is Fn + 20%, while the minimum FS is Fn – 20%.
FS will align automatically with Fn whenever a new Fn is set.
When increasing the supply frequency, pay attention not to exceed the Max. phase current of the
motor, otherwise there is a risk of blockage due to current overload in the output stages oF.
8.6.5 FL : Setting the minimum frequency
FL is used to set the minimum frequency at which the electropump is to be run.
The minimum value may be assumed to be 0Hz, the maximum value is 60% of Fn.
For example, if Fn=50Hz, FL may be regulated between 0Hz and 30Hz.
FL will align automatically with Fn whenever a new Fn is set.
8.6.6 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.
8.6.7 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.

ENGLISH
48
8.6.8
AE : Enabling the anti-block/anti-frost function
It starts rotation of the motor-impeller assembly so as to avoid mechanical blockages due to low temperature or to
long inactivity. When the function is enabled, if the ACTIVE DRIVER measures a temperature that is too low and
with a risk of frost, it automatically starts to turn the electropump at a low number of revs (25Hz). Instead, if the
temperature is within a safety range and the ACTIVE DRIVER records long inactivity, to avoid blockages of
formations of residue it makes the electropump perform an unblocking cycle every 23 hours.
ATTENTION: Since a starting frequency close to the rated value is necessary for a certain time in order to ensure
the starting of a single-phase pump, whenever the anti-frost function starts up with the users closed there may be an
increase in the pressure of the system.
It is important to ensure that the electropump installed has a maximum head that the system can withstand.
Otherwise it is advisable to deactivate the anti-frost function.
8.6.9
Setting pump start
The minimum frequency at which a single-phase pump can be started is an extremely variable parameter, depending
on the pump model used. It has therefore been made possible to set the starting frequency and the time during which
that frequency must be maintained in order to guarantee the correct operation of any model. The pre-set values of SF
and St are a good compromise, but if the pump does not start, or starts with difficulty or slowly, increase SF or St
until good pump operation is reached. If there are problems of excess pressure at starting, it will instead be necessary
to decrease the SF or St parameters. In this case it is recommended to vary one parameter at a time in small steps and
to check operation. The phenomenon of excess pressure at starting is typically found only for very low SP vales (1.0-
1.5 bar) and it may be limited, but not completely eliminated, by decreasing the parameters indicated above.
8.6.10
SF : Setting the starting frequency
This is the frequency at which the pump has to be started for the time St.
The pre-set value is 45 Hz and it may be varied between Fn and Fn-50% using the “+” and “-“ keys.
If a FL higher than Fn-50% has been set, SF will be limited to the value of the minimum frequency FL.
For example, for Fn=50 Hz and FL=0, SF may be set between 50 and 25 Hz; instead, if Fn=50 Hz and
FL=30 Hz, SF may be set between 50 and 30 Hz.
8.6.11
St : Setting the starting time
The parameter St represents the period of time during which the frequency SF is supplied before passing the
frequency control to the automatic system PI. The pre-set value of St is 1 second and it is the best value in the
majority of cases. However, if necessary, the parameter St may be varied from a minimum of 0 seconds to a
maximum of 3 seconds.

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 and SET and – for 5 seconds ) and set the
correct motor data plate current (parameter rC as in paragraph 8.5.1.)
13. ERROR AND STATUS CONDITIONS (ref. Table no. 14 page 53)
The ACTIVE DRIVER is equipped with protection systems to preserve the pump, the motor, the
supply line and the ACTIVE DRIVER itself.
If one or more protections trip, the one with the highest priority is immediately notified on the display.
Depending on the type of error the electropump may switch itself off, but when normal conditions are restored
the error status may be cancelled immediately or only after a certain time, following an automatic reset.

ENGLISH
51
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), 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.
In the case of excess temperature, the protection intervenes in two ways:
 blockage on reaching too high a temperature,
 limitation of the maximum frequency as the temperature rises.
Another type of protection is adopted on:
 the power device,
 the supply capacitors,
 the printed circuit.
These protections intervene when a potentially dangerous temperature is reached, limiting the maximum rotation
frequency FS to small steps.
Once the alarm is over the protection is automatically disabled and normal operating conditions are restored. The
invention of one of these three protections or a combination of them may at the most decrease the frequency FS by
20%.
The three protection systems do not cause and do not generate an error message, but they keep a trace of their
intervention by generating a warning in the fault log.
If the temperature on the final output stages or on the printed circuit is not limited with this system, the blockage for
excess temperature will intervene.
During the intervention of these protections a rotation frequency FR less than the expeted one
may be displayed.

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
bP : Blockage due to fault of the pressure sensor
If the ACTIVE DRIVER is unable to detect the presence of the pressure sensor, the electropump remains
blocked and the error signal “bP” is given. This status begins as soon as the problem is detected and ends
automatically 10 seconds after correct conditions have been restored.
13.3 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.

ENGLISH
52
13.4 oF/ot: Blockage due to current overload in the output stages with temperature of the stages higher
than 45°C
The letters “oF” and “ot” are shown alternately on the display, indicating that a current higher than the safety
threshold has been detected in the output stages and that the temperature of the stages is higher than 45°C.
This means that it might be possible to restart the electropump once the stages have cooled down. The
operating principle of this protection is as follows: since single-stage pumps are characterised by a high
starting current, to make it possible to protect the stages both at starting and during normal operation, 2
different protection thresholds have been introduced.
Moreover, the protection threshold for starting decreases as the temperature of the output stages increases, so
that it will be easier to have a blockage for current overload when trying to start a single-phase pump when
the stages are too warm.
13.5 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!
13.6 MANUAL RESET of error condition
In error status the operator can reset the error by forcing a new attempt, pressing the +and –keys
simultaneously.
13.7 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
bP Blockage due to fault of the
pressure sensor - Reset 10 seconds after correct conditions return
LP Blockage due to low supply
voltage
- Reset when voltage returns to a value in the range
220V - 20% + 10%
HP Blockage due to high
voltage
- Reset when the internal voltage returns in acceptable
conditions
Ot Blockage due to overheating
of the power stages
- Reset when the temperature of the power stages falls
below 70°C again
OC Blockage due to current
overload - An attempt every 10 minutes for a total of 6 attempts
oF
Blockage due to current
overload in the output
stages
- An attempt every 10 minutes for a total of 6 attempts
oF/ot
Blockage due to current
overload in the output
stages with temperature of
the stages higher than 45°C
- An attempt every 10 minutes or when the temperature
has fallen by 10°C. The counting of the attempts is
shared with that of the blockage oF.
