EDU 2AE and EDU 2AE/HPROpower supply and control units are an innovative system for controlling the
torque of any current control MITO and PLUTO electric screwdrivers: MITO15, PLUTO 3, PLUTO 6,
PLUTO 10, PLUTO 15, PLUTO 20, PLUTO 35 snd PLUTO50, either inline, pistol, for automation and
with angle head (only PLUTO). It’s also possible to use the following clutch models: PLUTO 3FR/HS,
PLUTO 5FR and PLUTO 7FR.

EDU 2AE and EDU 2AE/HPROdeliver 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.

2)Ramp:0.3s

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 could give as result a different torque level
from the one that results when the ramp is over. This is due to the motor acceleration.

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) Torque: you can select the desired torque as a percentage of the torque range of the selected screwdriver.
For example, for a Pluto10, a 50% setting will result in a torque in the area of 4.5 Nm. The torque range is
always referred to the MAX speed. In case you’re not working at maximum speed, the torque range will

progressively lower in order to avoid motor stalling. If the torque level is reached correctly, it will be
showed on the display and you will hear a beep sound, too.
Such torque level is indicated as “ T: ..% ” on the main screen.

4) TM Fast Spd (Time Fast Speed): It indicates how long the screwdriver should turn at the FAST SPEED
speed (see point 6) before switching to “pre-set speed” (lower speed). The “pre-set speed” is the speed set at
point 4. This FAST SPEED time can be set from 0.3 to 10.0 sec.
To disable the function press until you get to OFF. In this case the screwdriver will automatically start at
pre-set speed (see point 6).

CAUTION: The aim of the FAST SPEED is only to speed up the approach time in case of long screws.
Reaching the torque at higher speed will result in inaccurate torque output. To avoid inaccurate torque
values we suggest first to set a shorter time, and then increase it.
Torque reached during the FAST SPEED won’t activate the torque signal and the message “Error FAST

SPEED” will be displayed on the main screen and 2 beep sounds. The red led will turn on, too.

5) Fast Spd (Fast Speed): You can select the speed of the screwdriver during the FAST SPEED. It can be
set between max speed and the pre-set one (see point 4).
This function is available only if the Time Fast Speed is active.

6) 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).

7) 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'.

ATTENTION: Max Time must be set at 20.0 sec.

8) 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.

9) 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.

10) 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.

11) Rev torque – Unscrewing torque: You can select the desired torque as a percentage of the torque
range of the selected screwdriver (see point 2). If the torque is set on MAX, the unscrewing torque is about
20% higher than the possible maximum torque, so that it is always possible to unscrew the tightened screw
(we suggest leaving this function on in normal use). If the setting is from MIN to 99% the unscrewing
torque with the same percentage will be equal to the settings of the screwing phase.
ATTENTION: If you’re using open-end wrenches, the unscrewing torque has to be set to MIN value in

order to bring the wrench back to the correct position.

12) Rev speed – Reverse speed: You can select any reverse speed value of the screwdriver between the

maximum and the minimum specific speed of every single screwdriver (see table with technical data).

The following menu is available in the HPROmodel only

13) Pre-Rev. (Pre-reverse): You can set a reverse before a screwing.

Time can set from OFF to 20.0 sec.
ATTENTION: Pre-reverse speed and torque are the same as Auto Rev.

14) PV torque: Period of time in which the screwdriver works at maximum torque before switching to the
torque that has been set by the user. You can set time from 0.1 to 10.0 sec. To disable the function select
OFF by pressing as many times as needed.
This function overlaps other time settings (fast speed, ramp time, minimum time, maximum time) from the
motor start on.
ATTENTION: This function is useful for applications where the prevailing torque is higher than the final
torque (for example trilobal screws or locknuts).

Please use this function with utmost attention because an incorrect use can damage both the assembly
and the screwdriver.

Torques reached during the max torque time won’t activate the torque signal. “Error tm max torque” will be

displayed and the red led will light up. You will hear two beep sounds, too.

15) Rotation: You can choose between right tightening (standard screws) or left tightening (left threaded
screws). All the other functions will adapt to the selected direction of rotation.

16) Calibration: ON allows to see the torque value on the main screen. OFF doesn’t show the torque

value.

(To modify the calibration parameters see paragraph Torque calibration).

17) Compens – Compensation: This function allows an increase or decrease of the displayed torque after

calibration. The available range is from 0 to ±55 Nm. For example: after calibration (see Torque calibration)
you make a screwing on your assembly and compare the value you see on the main screen display with the
value you see on a torque tester (for example a mini-K or a K model). Let's say you notice that the torque
displayed in the unit EDU 2AE is +0.2 Nm higher than the value indicated on the tester (which is the right
one). In this case you change this value by setting -0.2 Nm so that the value on the screen will be the same
as the value on the tester. If it’s lower than 0.3 Nm, you need to set +0.3 Nm and so on.

18) Torq min – Minimum torque: The minimum torque and maximum torque options allow the user to set
the acceptable torque range for each single application. When the reached torque is inside this range,

“tightening OK” will be displayed on the status bar and the green led will light up. If the reached torque is
outside this range the messages “error minimum torque” or “error maximum torque” will be displayed. You

can set the torque range from 0 to 40 Nm at intervals of 0.01 Nm.
The minimum torque option allows to set the lowest value of the torque range and it’s on if calibration is
'ON'. If calibration is 'OFF' the minimum torque value automatically sets on 0 Nm.

19) Torq Max – Maximum Torque: The minimum torque and maximum torque options allow the user to
set the acceptable torque range for the single application. When the reached torque is inside this range,

“right screwing” will be displayed on the status bar and the green led will light up. The messages “below
minimum torque” or “over maximum torque” will be displayed if the reached torque is outside this range.

You can set the torque range from 0 to 55 Nm at intervals of 0.01 Nm.

The maximum torque option allows to set the highest value of the torque range and it’s on if the calibration

is 'ON'.

20) Screws number: The EDU2AE/HP and the EDU 2AE/HPROcan 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 OK/ESC function is disabled (see point 23), “Program end” will
