EDU 2AE/FR power supply and control unit is an innovative system for controlling the torque of any clutch
model of PLUTO clutch series: PLUTO 3FR/HS, PLUTO 5FR and PLUTO 7FR. Of FAB series: FAB03,
FAB10, FAB12 and FAB18. And of RAF series: RAF32, RAF38 and RAF50.
They are available either inline, pistol, for automation and with angle head (only PLUTO).
EDU 2AE/FR delivers all the advantages of precision torque control electric tools at a fraction of the price
of transdurized tools.
The state-of-the-art electronic control circuit cuts the power supply to the motor calculating the correct
torque in response to 3 parameters; voltage, frequency and current, according to the selected options.
The AC 90÷260V - 50÷60Hz power supply is converted into 40VDC required by the PLUTO series
screwdrivers through a switching board.

1) Model: you can select the screwdriver to be used. Your choice will automatically change the default
settings. It’s important to select the correct model you’re going to use since many parameters regarding the
motor software are specific for every single model.
2) Ramp: You can select the slow start time (acceleration) from 0.2 to 3.0 sec. This option is only available
for the screwing phase, while during the unscrewing phase the ramp time is always 0.2 sec. We suggest
using this option with self tapping screws.
ATTENTION: Reaching the torque while the ramp is still on will activate the “screw OK” signal anyway
(this option is useful if you need to tighten screws that are already tightened, the so called “double hit” ).
On the other hand, if you wish to see an error signal during the preset torque in the ramp phase, you can
change the minimum time by setting value which is equal or superior to the ramp value (see point 8).

3) Final Spd (Final Speed): You can select any speed value of the screwdriver between the maximum and
the minimum specific speed of every single screwdriver (see table with technical data).
4) Run time: You can set the time of a tightening, from OFF to 20.0 sec. When the pre-set time has been
reached, it results in a torque signal.
The couple reached during this time results in a signal of Correct screw. If the correct screw signal is not
required, set the Minimum time up to a value of 'Minimum Time -0.1sec'.

Vers. 210920 5
ATTENTION: Max Time must be set at 20.0 sec.
5) Min Time - Minimum Time: You can set this time from 0.1 sec to 'Max time - 0.1s'. To disable the
function select OFF by pressing as many times as needed. (Min time = 0).
Torque reached below the minimum time won’t activate the torque signal and will result in an error
signal. “Below minimum time” will be displayed on the status bar and the red led will light up. You will
hear two beep sounds, too.

6) Max time - Maximum time: You can select the maximum time of tightening. You can set from 'Min
time + 0.1s' to 20.0 sec.
You also can set the Maximum time to OFF by pressing the button when you have reached the value
of 20.0s. In this case the screwdriver turns without any time limit.
ATTENTION: If torque isn’t reached by the maximum time, the screwdriver will stop. “Over maximum
time” will be displayed on the status bar and the red led will light up. You will hear two beep sounds, too.
7) Auto Rev: This option will automatically start a reverse after a torque reached/ correct screw signal. You
can set time from 0.1 to 20.0 sec.
To disable the function select OFF by pressing as many times as needed.
ATTENTION: During the reverse, it is necessary to keep the lever or the start signal pressed as long as it
won’t stop. “Correct screw” will be displayed on the status bar and a green led will light up. You will
hear one beep sound, too. In case the lever is released before the end of the reverse, “unfinished screw”
will be displayed and a red led will light up. You will hear two beep sounds, too.
8) Screws number: The EDU2AE/FRcan act as screw counter. You can set the number of screws from 1 to
99. To disable the function select OFF by pressing as many times as needed.
If the number of correct screws is equal to the number of set screws “Program end” will appear on the status
bar and the yellow led will light up. If the Press OK function is disabled, “Program end” will automatically
disappear at next screwing or when you enter the menu. Otherwise, press OK at the end of each program.
ATTENTION: Every time you enter the menu, the number of screws resets to zero.
Unit Options
1) Language: This option allows to select among 4 languages: English, French, German, Italian, Spanish
and Portuguese.
2) Versions:in this screen you can see the versions of boards inside the unit.

3) Cycles - Number of total screwing/errors done which have been carried out: It shows the number of
fastened screws and occurred errors. This number can’t be modified.
4) Change password: You can change password (see point 5).
5) Password: If YES, you will be asked for the password to enter the menu. Otherwise select NO.
ATTENTION: Password is only asked to enter the menu for the first time after switching the unit on.
The default password is: 0000.
6) Press OK: when ON, press OK at the end of each screwing.
When OFF, the control unit resets automatically after a screwing.
7) Press ESC: when ON, press ESC to reset the control unit.
When OFF, the control unit resets automatically after an error signal.
INTERPRETATION OF ACOUSTIC SIGNALS
The control unit emits sounds which help you understand if the screwing has been carried out correctly or
not. When the torque is reached meeting all the parameters set, the control unit utters a 0.5 sec beep as
confirmation. In case of Program End, the unit will utter other two beeps. Instead, torque reached under min
time, during the Ramp time or under the Fast speed (see error signals on the display) will cause the control
unit to utter three beep sounds.

I/O CONNECTIONS
EDU 2AE control unit series have connectors placed on the back panel. These connectors allow to enable
functions through inputs and to take signals through outputs. The inputs are activated by connecting them to
ground. A positive voltage must NEVER be brought to these inputs. Bringing 24V to the unit inputs could
damage the inputs themselves. As seen from the picture below, to enable the inputs it is recommended to
bring a clean contact by using a relay or a simple switch or button.
As for the outputs, they are all PNP type with active function. On each pin you will have 24V DC.
These pins can be used directly connected to PNP inputs (PLC) or used to turn on LEDs, buzzers or other
devices with 24V power supply. The maximum total power of the outputs is about 400mA. Using inductive
loads such as relays or other loads with an initial consumption peak greater than 400mA will send all
outputs to protection, displaying the message "output disable". To restore the outputs after a protection, turn
off and turn on the unit again.

On the back panel, in all the EDU 2AE units, there is a 10 pin I/O connector.

results of each screwing. The transmission characteristics are the following:
9600 (bits per second), 8 (data bits), n (no parity), 1 (bits stop 1).
Connection pin: PIN 2 = TX, PIN 5 = GND
The print string is the following:
RESULT

MODEL
SPEED
SCREW
COUNT
NOTICE
Result = screw evaluation: correct or incorrect.
OK = the torque has been correctly reached, all the selected parameters are satisfied and the control
unit will give out a beep sound of 0.5 sec.
NOK = the torque has been reached during the ramp time or the fast speed (see error table). In this
case, the unit will give out 2 beep sounds and the red led will light up.
Screwdriver model =model of selected screwdriver.
S: Speed = speed value.
Screws: Count = number of screws screwed/number of total screws of the sequence/ program.
Notice = in case of program end, it prints “Program End” or it indicates the type of error (see paragraph:
trouble shooting).
