FE230/T - Digital speed regulator for single-phase
induction motors with temperature probe
The FE230/T module is an advanced electronic control
system with microprocessor dedicated to the manual
or automatic speed regulation of a single phase
induction motor (typically intended for applications of
air suction), to the management of the lighting system
and a solenoid for the gas supply (or other type of
load such as, for example, an external solenoid for the
chimney’s opening). The accuracy and the practicality of use are guaranteed by
the use of a last generation microprocessor and by digital commands on the
front panel. This model can work both in manual or automatic mode. The in-
structions below explain its functioning.

Technical features
The regulator can be controlled/configured via the 5-key keypad.
Keyboard:
SW1 key: motor starts running, allow s the acces to the configuration menu and it is
used as confirm key when navigating the configuration menu.
SW2 key: torn off the motor, reset the filter usage counter
and the filter alarm and it is used as the "Exit" button when navi-
gating the configuration menu.
SW3 key: increases the speed of the motor, allow s naviga-
tion in the Configuration Menu and allows to enable / disable the
Automatic operation.
SW4 key: decreases the motor speed and allow s naviga-
tion within the Configuration Menu.
SW5 key: turn on/off the light.
8-segments display
It provides indications on the operating status of the regulator and in particular:
 speed implemented by the motor
 any automatic mode active
 any alarms in progress
 Menu level and configuration values in the Configuration Menu.
The display point gives additional indications:
 when it is fixed it indicates that it is inside the Configuration Menu;
 when it is flashing it indicates a phase of transitory operation: accelleration, waiting time
to open the gas solenoid valve, waiting time for the motor turning off.
Led
The status of activated Gas Solenoid Valve is indicated by the illiminated LED.
Management of the suction motor, the gas solenoid valve and the lights
The motor can operate in:
 Manual mode, 8 preset speeds controlled by Keypad.
 Automatic mode, with the supplied NTC temperature probe connected, to automatically
adjust the motor speed according to the temperature detected by the probe. Instaed of
the NTC temperature probe it is possible to manage a digital input for the control of a
thermal contact (normally closed) typically destined to the protection of the motor win-
dings: for further information related to the Automatic Mode and to the logic of opera-
tion of the aforementioned digital input, refer to the dedicated paragraphs.
In the transition from one speed to the other, as well as at switch-on and switch-off, the mo-
tor always follows an appropriate ramp.
Motor start procedure
When the ignition command is given (SW1 key) the motor starts for 3 seconds at the
acceleration speed (settable) and then automatically switches to speed 1.
Once the set time has elapsed (see the relative configuration mode), the Gas Solenoid valve
is activated with the relative lighting of the DL LED.
Motor shutdown procedure
At the shutdown command (SW2 key), the gas solenoid valve is immediately deactivated and
this event is signaled by the DL LED: the motor starts to suck at maximum power (speed 8)
for the set time (see relative configuration mode), after which it stops. During the transitory
phase that leads to the actual switching off of the engine, the Display Point flashes and the
speed can be changed manually.
Motor management
With the engine running it is possible to:
- Increase the motor speed in sequence (V1 - V2 - ... - V7 - V8) using the SW3 key on the key-
board;
- Decrease the motor speed in sequence (V8 - V7 - ... - V2 - V1) using the SW4 key on the key-
board.
It is not possible to start the engine with the Speed Increment command and the engine can not
be switched off with the Speed Decrease command.
Light Management
At any time and in any operating condition the light can be switched on or off using the SW5
key on the keyboard.
Automatic operation
When an NTC temperature probe is connected to the digital controller, it is possible to enable
the Automatic Mode to obtain an automatic and linear adjustment of the motor speed according
to the temperature measured by the NTC probe .
The Automatic Mode is activated and deactivated alternately keeping the SW3 key of the
keyboard pressed for about 2 seconds when the motor is off and not in the configuration menu.
The activation of the Automatic Mode is signaled by the temporary display of the letter "A";
while the deactivation of the Automatic Mode (ie the return to Manual Mode) is signaled by the
temporary display of the number "0".
In Automatic Mode, the speed varies between the minimum and the maximum speed set for non
-automatic operation: the latter are controlled at settable temperature limits.
The Automatic Mode is active with the motor running, if the regulator is not in the condition of:
- configuration via Menu;
- initial acceleration;
- motor shutdown delay.
The automatism does not control the ON and OFF of the motor-driven fan, but, if activated,
regulates its speed.
The automatic operation of the fan is indicated by the letter "A" which alternates with the
indication of the non-automatic speed closest to the current one.
To optimize the automatic operation according to the probe position and the size of the
extractor hood, it is possible to set from the menu the two temperature limits corresponding to
the minimum and maximum engine speeds (see the paragraph dedicated to the Configuration
Menu); for intermediate temperatures an intermediate speed is implemented.
Management of a thermal contact for the protection of the motor windings
As an alternative to the NTC temperature probe it is possible to manage a digital input for the
control of a thermal contact (normally closed) typically intended for the protection of the motor
windings. If this configuration is used, the Manual Motor Speed Adjustment Mode must always
be selected.
As long as the thermal contact is closed, all the functions of the digital controller can be
managed:
 turn the engine on/off and increase/decrease the speed by pressing the appropriate keys on
the keyboard;
 turn on/off the light;
 access the configuration menu and reset the filter counter.
When the contact opens, any loads that are switched on are switched off and the display shows
the indication "c" flashing; if, before the power supply to the regulator is disconnected, the
thermal contact closes, the functions that were active before the event of opening the contact
are restored (unless the engine shut-off keys have been pressed in the meantime) and/or light).
As long as the thermal contact is open, it is only possible to access the configuration menu and
reset the filter counter: any attempts to switch on the engine and / or light have no effect.
Note: w ith the thermal contact open and in the presence of an eventual filter alarm,
the display alternately shows the letter "c" and the letter "F" indicating active filter alarm.
Visualization and management of alarm conditions
when the NTC temperature probe is connected to the controller
In critical operating conditions (for example, when the Automatic Mode is active or if the NTC
probe wiring may be damaged), the digital controller signals an alarm condition; in particular:
1) if the NTC temperature probe is not detected (possible damage to the wiring) or if it returns
temperature measurements below the minimum permissible limit, the display will show the
letter "c" flashing and possibly alternating with other indications such as specified below;
2) if the NTC temperature probe returns temperature measurements above the maximum
permissible limit, the display will show the letter "E" flashing and possibly alternating with other
indications as specified below.
If the alarm condition occurs with the Automatic Mode activated, the automation remains
inhibited until the correct functioning of the probe is restored and:
 if the anomaly occurs with the motor running, then the maximum speed set for the motor
is activated and the display shows an alarm code (represented by the letter "c" or the letter
"E", as specified above) alternating with the indication of the current speed; in this situation
it is always possible, by pressing the appropriate keys on the keypad, to set a different
speed of the motor as well as switch off/on the light and the motor;
 when the motor is switched off, a flashing alarm code appears on the display (represented
by the letter "c" or the letter "E", as specified above); in this situation it is always possible,
by pressing the appropriate keys on the keyboard, to switch on / off the light and the motor
and, if necessary, set the desired speed;
 if the anomaly is signaled by the letter "E" you can deselect the Automatic Mode (by pres-
sing for about 2 seconds the SW3 key of the keyboard, as already specified above) in order
to use the controller according to the Manual Mode without having any alarm signal to di-
splay;
 if the anomaly is signaled by the letter "c" the controller can not be used by deselecting the
Automatic Mode: in fact, if in this situation the SW3 key of the keyboard is pressed for about
2 seconds to activate the Manual Mode, the display shows the letter "C" flashing and the
light and motor ignition commands are ignored.

Restore default settings
To restore the default configuration of the controller, enter the Configuration Menu (first menu level) and keep
the SW3 and SW4 keys pressed simultaneously for at least 3 seconds; the exit from the Configuration Menu
with simultaneous temporary display of the letter "d" indicates the successful restoration.
This operation involves restoring the default conditions for:
 the 8 speeds of non-automatic operation
 the starting speed
 the activation delay of the gas valve when the fan is switched on
 the delay in switching off the motor
 the hours of filter saturation (Alarm disabled)
 Automatism (disabled).
If the alarm condition occurs when the Automatic mode is deactivated, only the anomaly related
to point 1 (NTC probe not detected or temperature measurement below the minimum
permissible limit) is signaled and managed, and in particular:
 if the anomaly occurs with the motor running, then the motor and the light are switched off
and the display shows the alarm code represented by the letter "c" flashing;
 after the motor and light have been switched off, any light and motor ignition commands are
ignored and the display continues to show the letter "c" flashing ;
 if the alarm condition ends before the power supply to the controller is removed, the active
functions are restored before the alarm occurs (unless these functions have been disabled
from the keypad or remote control after the alarm event occurs same); with the alarm retur-
ned, the display no longer shows the letter "c" flashing;
 if with active alarm the Automatic Mode is selected (by pressing the SW3 key of the key-
board for about 2 seconds, as already specified above) the automatism will be inhibited,
but it will be possible to use the controller to switch the light on / off, switch on / off the
motor and change its speed using the appropriate keyboard commands; in this case the di-
splay shows the letter "c" alternating with the indication of the current speed.
Note: w ith NTC probe alarm in progress and in the presence of a possible filter alarm,
the display alternately shows the alarm code (represented by the letter "c" or by the letter "E",
as specified above) and the letter "F" for signaling active filter alarm.

ting the starting, minimum and maximum speed; use the UP button to switch to the "T" menu.
With the ESC key, you exit the Configuration Menu.
Use the ENTER key to enter the submenu to set the starting speed "b" (boost). The motor mo-
ves to the minimum speed that can be associated with this parameter (it should be noted that
this speed, depending on the type of load applied, may not be sufficient to start the engine, in
which case press the UP key to increase it when the engine starts). The speed can be changed
to the desired point with the UP and DOWN keys.
With the ENTER key, the current speed is acquired as the starting speed and the minimum "L"
speed setting submenu is entered (Low); with the UP and DOWN keys the motor speed can be
brought to the desired minimum level; it is not possible to select a speed greater than that
chosen for the starting speed.
With the ENTER key, the current speed is acquired as minimum speed (1) and the submenu for
setting the maximum speed "H" (High) is entered; the motor goes to the maximum speed (8)
that can be changed to the desired point with the UP and DOWN keys.
With the ENTER key, the current speed is acquired as the maximum speed (8); the
intermediate speeds are automatically calculated; the 8 speeds plus the inrushing speed are
memorized and you return to the "P" menu.
Pressing the ESC key in the submenus "b", "L", and " H" returns to the " P" menu w ithout
saving any speed settings.

menu.
Pressing the ESC key returns to the "t" menu without saving the current setting.
Regulator installation
After removing the cover, make the necessary holes on the box for the passage of the cables,
the cable glands and of the temperature probe. Then set the box to the desired support and
connect to the terminal block on the board respecting the connection scheme. (Note: If the
motor used in the installation has a metallic chassis, it is recommended to connect this to the
one of the two terminal blocks on the board. The second terminal then will be connected to
the earth by the eletricity grid). Connect the temperature probe to CN1 connector on the
board.
After making the connections, provide supply to the regulator. This will remain in low power
mode (standby) until will be activated outputs or will enter to the Configuration menu.
Check the outputs correct operation using the special keys on the front panel.
Then close the cover using the screws: the device is ready for use.
