2.1 General information
2.2 Description and technical characteristics
2.3 Security measure
This manual is directed to manufacturers, installers and service agents of ventilation equipment specialized in the appli-
cation, installation and adjustment of industrial fans.
2.1.1 Purpose and limits of the use of the manual :
This manual is intended for specialized and adequately trained personnel in the realization of machines or equip-
ment using centrifugal electric fans, preventing preventive errors from the use and installation of such devices.
However, the present recommendations are not the only methods, procedures or other devices for obtaining
security in the represented situations. Always be rigorously careful when moving around moving parts or parts
under tension. Safety depends only on skill, experience and reasonable attention in the actions performed on the
machine.
To operate safely on the electronic fan during installation and maintenance, use individual protective equipment (eg.
gloves) as provided for in Directive 89/686 / EEC (and its successive amendments).
2.2.1 Description :
For a description of the fans, refer to the manual.
2.2.2 Technical features and expected use :
The current electric fan is adapted to transfer non-toxic, non-ammable, non-corrosive air without liquid or solid or
abrasive particles and the temperature does not exceed 40 ° C (UNI EN ISO 13349).
Different temperature and humidity limits are indicated on the fan label. The electric fan must only be operated
with the electrical power supplied by the indication on the label.
In addition to these recommendations, before performing any activities related to the use of this machine, you
must be informed of the required security applications based on the laws, rules and standards applicable to the
installation site
Displacement, installation and maintenance must always be carried out by
trained and trained technicians.
Any installation by unskilled people is therefore prohibited
Attention: The current electrical fan is built to be mounted in a machine and therefore cannot be used
autonomously.
Attention: the present electric fan must be protected against the risks of mechanical type, the risks due
to the projection, the risks due to the electric energy and the risks due to the extreme temperatures (the
engine can reach surface temperatures above 70 °C) in all cases the electric fan must be installed on the
machine taking into account all necessary safety measures, in order to avoid any danger arising from its
application, in accordance with the requirements of Machine Directive 2006/42 / EC (and its successive
amendments). As an indication, we advise you to apply the content of technical standards UNI EN ISO
12100, UNI EN ISO 13857, CEI EN 60204, UNI EN ISO 12499.
Note: the sound power level emitted by the machine is indicated on the label when it exceeds Leq = 85db
(A). The weight of the fan is indicated on the label when it exceeds 30kg. These indications must be taken
into account to provide the appropriate protection for the machine.

2.4 Installation operations
2.5 Use and operation
The correct installation of the electric fan ensures the solution of many problems that could arise during its use.
The fan must be used only for the purpose for which it was designed (par.2.2.2) and introduced into the machine with all
the protections to prevent any risk to persons and things.
Use out of predetermined limits can lead to dangerous situations not considered and independent of the responsibility of
the manufacturer.
Installation phases:
a) check if parts are damaged or missing;
b) check that the wheel rotates freely and that there is no sign of excessive imbalance or play on the motor shaft
c) Insert the fan into the machine by securing it with the anchor holes on the fan housing or through the holes on the
ange, if tted, or holes of the brackets that are part of the supply. The electro ventilator must have a space between
the suction gates and the walls of the machine to not punish the aeroulic and sound characteristics, this distance must
at least be the diameter of the wheel. The diameter of the wheel can be found in the description on the label, which is
expressed in pulses (if it is three digits, it is expressed in millimetres);
d) connect the electric fan according to the attached connection diagram and also present on the electric fan, also
veries that the supply voltage for the test does not exceed the ones indicated on the label of the electric fan;
e) during the test phases of the machine, check that the direction of rotation coincides with that indicated by the
orientation arrow on the electric fan and that the current absorption does not exceed the one indicated on the label;
f) Check the protections specied by the project so that the machine complies with the requirements of the
89/392 / EEC directive in the protection of the electric fan, and that these are adequately installed.
CAUTION: do not remove the safety protections provided; do not intervene on
the electric fan without rst turning off the voltage and wait until the wheel has
stopped
Attention: the displacement of the electric fan could be difcult given its shape and the uneven distribu-
tion of the weights.
Attention: Turn off the power of the machine before you start the installation process.
Attention: the electric fan must be installed with the motor shaft placed horizontally with respect to the
ground
Caution: before operating the electric fan control that the voltage of the power supply corresponds to that
shown on the label
Attention: the electric fan must operate only within the limits of operation (power supply, temperature,
etc.) indicated on the label.

3. DIGITAL SPEED CONTROL
FE230 regulator is an advanced control system using a micropro- cessor for manual or
automatic speed adjustment of an induction single-phase motor (typically used for air
intake systems), for lighting system management and for a possible optional load
(such as, for example an external gas solenoid valve for chim- ney or gas outlet).
The precision and its use ease are guaranteed by using a latest generation
microprocessor and by digital controls situated on the front panel: picture 2 and the
following instructions illustrate the functions managed by FE230 control unit, these
functions turn the control unit into an ideal solution for many indoor and pro- fessional air
intake systems (odours, smokes and fumes extrac tors fan, indoor, professional and
industrial range hoods, purication and air treatment devices, etc...).
Special attention in designing FE230 control system has been dedicated to achieve an innovative electronic control sys-
tem, characterized in stand-by condition by lower power consumption cur- rently available for these kind of product.
This feature, particularly appreciated today, and the possibility to automate air intake system by optional sensors, allow
to install a sophisticated and efcient air-treatment system control in every kind of settings. The possibility of using
wireless remote control (IR/RADIO code FE1004) or RS- 485 serial channel turn FE230 system into a “clever” system
control that is able to set up new features that can be implemented according to custom requirements.
The manufacturer declares that this product is free from manufacturing defects. The guarantee lasts 12 months if the
product is correctly used.
The manufacturer reserves the right to make changes, also without notice, on the de- vice or on the documentation in
order to improve its performances.
WARNINGS:
•Before installing and plugging the device into the mains, check that the specications indicated on the data plate
and the technical characteristics explained on this manual correspond to those of the electrical mains system, of
motor, of lighting system and of eventual gas solenoid valve.
• Use always high quality and suitable section electric cables wire to connect the regula- tor to the mains and to
loads.
• We recommend that you keep within the device the lenghts cable short to avoid their contact with particular compo-
nents that could reach high temperatures.
• Install the regulator in ventilated places and away from sources of heat, especially if the current load absorption are
close to the maximum declared.
• Be sure to connect the ground wire of the motors (or the chassis of the motors) to the main board and the latter one
to the grounding system of the network.
•To avoid danger of re, electric shock or malfunctions, do not expose the device to rain, humidity, favouring the
installation in a dry place. It is recommended to not in- stall the regulator in areas with moisture, fumes or gas, avoid
direct sunlight or heat sources that could damage the device dissipation capacity.
• The regulator must be installed and used only in compliance with the instructions pro- vided: the manufacturer won’t
be responsible for the improper use of the device (if it is used for applications different than those for which it was
designed) or for failure to

When loads are off, it is possible to do the calibration procedure of the motor speed, by which the user can customize
the value of the minimum, maximum and start speed. After completing the calibration procedure, intermediate speeds
(the speed 2 to 7) are dened by software based on the minimum and maximum setting.
If the user does not perform the calibration procedure for setting the minimum and maxi- mum motor speed, these pa-
rameters have default values.
Press and hold simultaneously for 3 seconds the keys SW3 and SW4 to access the cali- bration procedure of the motor
speed:
the display shows «0», indicating that it is enabled the start speed, and is automatically selected minimum speed that
can be associated to that parameter (it should be noted that this speed, depending on the type of load applied, it may
not be sufcient to start the motor:
in this case press the button SW3 to incre- ment until the motor starts).
Push the SW3 and / or SW4 to increase and / or decrease the speed until you get the desired value for the start speed.

After removing the cover, do on the box the necessary holes for the passage of cables.
Then attach the box to the desired support and make connections to the terminal block on the board according to the
connexion diagram shown in Fig. 3 (Note: If the motor used in the installation has a metal chassis, it is recommended to
connect it to one of the two ground terminals on the board. The second terminal must be connected to the earth of the
mains).
When all connections have been done, power on to the regulator.
This will remain in low power mode (stand-by) until loads are activated or you will access the Congu- ration Menu.
