EDU 2AE/TOP/MITO power supply and control units are an innovative system for controlling the torque of
any MITO electric screwdriver either inline, pistol, with angle head or for automation.
EDU 2AE/TOP/MITO 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.

3) 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 most parameters regarding the
motor software are specific to every single model.
4) Torque: you can select the desired torque as a percentage of the torque range of the selected
screwdriver. 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 shown on the display and you will hear a beep sound, too.
Such torque level is indicated as “ T: ..% ” on the main screen.
5) Joint: You can select the type of joint you are working on. A soft joint is typically a self tapping screw
on plastic or sheet metal, or a metric (machine) screw on a material subject to strain (for example: gasket, o
ring etc.) A hard joint is typically a fastener joining metal with metal.
If you select the option SOFT the screwdriver will run the complete cycle at the selected speed (see point
6.). When selecting the option HARD the screwdriver will maintain the selected speed for a selected time
after the start (see point 4.) and then the speed will be reduced automatically to apply a pre-torque before
reaching the preset torque. The type of joint is indicated as “J” on the main screen.
IMPORTANT: An incorrect selection of the joint type can result in inaccurate torque output.

6) Brake time: This option can be selected Uonly Uin combination with the option JOINT: HARD.
It indicates how long the selected speed (higher speed) will be on before switching to “pre-torque speed”
(lower speed). The “pre-torque speed” will be automatically chosen by the unit depending on the preset
torque. You can set the brake time from 0.3 to 10.0 sec.
To disable the function select OFF by pressing as many times as needed. In this case the screwdriver will
automatically start at pre-torque speed, which cannot be set by the user.
CAUTION: The aim of the BRAKE TIME 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 selecting a shorter time, and then increase it step by step until finding the optimum time.
Torque reached during the Brake Time won’t activate the torque signal and the message “Error brake
time” will be displayed on the main screen together with 2 beep sounds. The red led will turn on, too.

Manual EDU 2AE/TOP/MITO Page 5
7) 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 9).
8) Speed:You can select any speed value of the screwdriver between nominal (maximum speed given in
the catalogue) and the minimum speed of every single screwdriver (see table with technical data).

9) 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.
10) Max time - Maximum time:You can select the maximum time of tightening. You can set from 'Min
time + 0,1s' to 20.0 sec.
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.
11) Auto rev. –Auto reverse: This option will automatically start a reverse cycle after a torque reached
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 cycle, 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 cycle, “unfinished
screw” will be displayed and a red led will light up. You will hear two beep sounds, too.

12) Rev spd - 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).
13) Rev torque –Unscrewing torque: You can select the desired torque as a percentage of the torque
range of the selected screwdriver (see point 3). 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.

Manual EDU 2AE/TOP/MITO Page 6
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.
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 (brake time, 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 pvt time” will be
displayed and the red led will light up. You will hear two beep sounds, too.

21) Compens –Compensation: This function allows an increase or decrease of the displayed torque
after calibration. The available range is from 0 to ±9.99 Nm. For example: after calibration (see Torque
calibration) you make a screwing cycle 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/TOP/MITO 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.
22) Unit: You can choose between the following units of measurements: Nm and in.lbs.
23) 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 in steps 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.

24) 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 40 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. If the calibration is OFF the maximum torque value automatically sets on 40 Nm.
25) Ins. barcode: to scan a barcode and recall the desired program. To be used in combination with option
4. of the Sequence Menu.
THE FOLLOWING MENU IS AVAILABLE ON TAVERSION ONLY

TORQUE CALIBRATION
Please read the instructions carefully and equip a torque tester to proceed.
The torque calibration function allows to view the torque value in Nm or in.lbs directly on the display.
ATTENTION: The displayed torque level is approximate and it’s determined by mathematical calculations.
The smaller the calibration interval the more precise the value on the screen.
IMPORTANT WARNINGS:
Calibration values will be referred to the parameters of the control unit which are set during
calibration. If you modify speed or type of joint, the unit will need to be recalibrated.
If the screwing cycle during calibration isn’t carried out correctly or if you’re not sure of the value
it’s possible to repeat it. A wrong screwing cycle can affect the precision of the calibration cycle.
Calibration is carried out for two torque levels optionally chosen. The minimum calibration interval
is 5% (example: if I have to work at 30%, I can calibrate at 25% and 35%) but we recommend a
minimum of 10% interval.

Manual EDU 2AE/TOP/MITO Page 10
Torque percentages which are higher than the maximum one set during the calibration will be
analyzed and displayed anyway. They will be theorized by the system and they won’t be based on
effective data, therefore the analysis won’t be precise.
During the calibration it’s impossible to go back to the previous screen. Press ESC to stop
calibration and then repeat the cycle.
CALIBRATION PROCESS:
1. Select Calibration at point 17 of the menu and press OK.
2. The following screen will appear on the display:

3. Choose if you want to set calibration ON or OFF, then press OK to confirm or ESC to exit. If you
choose OFF calibration will be interrupted and no torque value will be displayed. If you choose ON
calibration will continue and the following screen will be displayed:
4. Set the first torque level percentage by pressing o , then press OK.
5. Complete a fastening cycle.
6. If you’re sure of the torque level displayed on your torque tester press OK, then set the displayed
value and press OK again to save. Otherwise press ESC and start again.
7. The following screen will be displayed. Set the percentage of the second torque by pressing or
and press OK.
8. Repeat the procedures described on points 4 and 5.
9. When calibration ends, “Setting end” will be displayed. You will hear two beep sounds, too.
ATTENTION: If you press ESC after confirming “calibration ON”, the display will show the torque screen
again and the displayed values are the default ones or the ones set during the previous calibration (if done
before).

USE OF T&A (Torque & Angle)
Choose the T & A mode (see point 26: Modify function on the program menu)
It is possible to set 6 different modes:
TORQUE (Torque): It’s the most common use mode. The control unit shows the tightening torque and
the torque starting from a certain torque percentage (threshold torque, see point 27). If the final torque
and angle values are within the preset minimum and maximum values, the screw is correctly tightened.
If the torque and/or angle are outside the preset values, the screw will be considered as incorrectly
tightened. In this case the red led will light up and the message “Error Max (Min) Angle” or “Error Max
(Min) Torque”will be displayed.
TORQUE/INPUT (T/IN): It corresponds to Torque mode, except for the threshold torque which
can’t be set by the operator: in fact the value is the result of an external impulse through a proper
contact (see paragraph “connections”). It can be very useful if the operator wants the control unit to
start counting the angle from a position which is indicated by a precision instrument.
TORQUE/LEVER (T/LV): No threshold is preset by the operator: the angle value that appears on
the display corresponds to the angle that is carried out starting from the moment in which the lever
is pressed until the torque is reached.

Manual EDU 2AE/TOP/MITO Page 12
ANGLE (Ang.): This mode gives priority to the angle to be reached. The value is measured starting
from a tightening torque percentage.
Starting from the preset threshold torque (see point 27) the system will start counting the degrees
and when the preset angle is reached the screwdriver will stop. If the preset angle is reached the
screw will be considered as correctly tightened, the green led will light up and the message
“tightening OK” will be displayed on the status bar. If the screwdriver stops before reaching the
preset angle the tightening will be considered not ok, the red led will light up and the message “error
angle not reached” will be displayed on the status bar. Therefore it’s very important to set a torque
value (line 4) which is sufficiently higher than the threshold value (line 27), so that the set value is
reached before the screwdriver stops because of the reached torque.
ANGLE/INPUT (A/IN): The threshold can’t be set by the operator: in fact the value is the result of
an external impulse through a proper contact (see paragraph “connections”).
This function can be very useful if the operator wants the screw to rotate a certain number of
degrees after reaching a position indicated by a precision instrument.
ANGLE/LEVER (A/LV): the threshold torque value can’t be set by the operator and the angle value
that appears on the display corresponds to the angle that is carried out starting from the moment in
which the lever is pressed

Manual EDU 2AE/TOP/MITO Page 13
INTERPRETATION OF ACOUSTIC SIGNALS
The control unit emits sounds which help you understand if the fastening operation has been carried out
correctly or incorrectly. When the torque is reached meeting all the parameters set, the control unit utters a
0.5 sec beep as confirmation. On the other hand, torque reached under min time, during the Ramp time or
under the Brake time (see error signals on the display) will cause the control unit to utter two beep sounds.
In case of wrong settings (e.g. both sequence and switchbox are enabled or the selected switch box program
is different from the one required by the sequence) the control unit will utter a long beep sound.
