EDU 2AE/TOP/NT power supply and control units are an innovative system for controlling the torque of
any current control NATO electric screwdrivers.
EDU 2AE/TOP/NT 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. Only NATO models.
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 displayed 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 at the selected speed (see point 8). Instead if you
select HARD, the screwdriver will maintain the selected speed for a selected time after the start (see point 6)
and then the speed will be reduced automatically to apply a pre-torque before reaching the desired 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 press until you get to OFF. 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 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.
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 result in a different torque level from the
one that results when at the end of the ramp. 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, you can modify the minimum time by setting value
which is equal or superior to the ramp value (see point 10).
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) Runtime: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.
10) Min time - Minimum Time:You can select the minimum time of screwing from 0.1 sec to 'Max
time - 0.1s'. To disable the function press until you get to OFF (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.
11) Max time - Maximum time:You can select the maximum time of screwing. You can set from 'Min
time + 0,1s' to 20.0 sec.

Page 6
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.
12) Pre-Rev.: pre-reverse. You can unscrew before tightening. This time can be set from OFF to
20.0 sec.
N.B. The speed and torque will be the same as those for the Auto Reverse.
13) Auto rev. –Auto reverse: This option will automatically start a reverse after a torque reached signal.
You can set time from 0.1 to 20.0 sec.
To disable the function press until you get to OFF.
ATTENTION: During the reverse, it is necessary to keep the lever or the start signal pressed as long as it
doesn’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.
14) 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).
15) Rev torque –Reverse torque: You can select the desired reverse torque as a percentage of the
torque range of the selected screwdriver (see point 2). If the torque is set on MAX, the reverse torque is
about 20% higher than the possible maximum torque, so that it is always possible to unscrew a tightened
screw (we suggest leaving this function on in normal use). If the setting is from MIN to 99% the reverse
torque with the same percentage will be equal to the settings of the screwing phase.
ATTENTION: If you’re using open-end wrenches, the reverse torque has to be set to MIN value in
order to bring the wrench back to the correct position.
16) 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 press until you get to OFF.
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.
17) 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.

24) Compens –Compensation: This function allows an increase or decrease of the displayed torque
value after a calibration. The available range is from 0 to ±9.99 Nm. For example: after calibration (see
Torque calibration) you make a screwing on your assembly and compare the displayed value to 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/NATO is +0.2 Nm higher than the value indicated on the tester (which
is the right one). In this case you can modify this value by setting -0.2 Nm so that the value on the display
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.
25) 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 within this range,
“Screw OK” will be displayed on the status bar and the green led will light up. If the reached torque is
outside this range, “error minimum torque” or “error maximum torque” will be displayed and the red led
will light up. You can set the torque range from 0 to ‘Torq Max-0.01 Nm’ in steps of 0.01 Nm.
The minimum torque option allows to set the lowest value of the torque range. When Calibration is OFF, the
minimum torque value automatically sets on 0 Nm.

The selection of the torque value is carried out by entering the digit cell by cell.
26) 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 within this range,
“Screw OK” will be displayed on the status bar and the green led will light up. If the reached torque is
outside this range, “error minimum torque” or “error maximum torque” will be displayed. You can set the
torque range from ‘Torq Min+0.01 Nm’to 55 Nm at intervals of 0.01 Nm.
The maximum torque option allows to set the highest value of the torque range. When Calibration is OFF
the maximum torque value automatically sets on 55 Nm.
The selection of the torque value is carried out by entering the digit cell by cell.

TORQUE CALIBRATION
The torque calibration function allows to view the torque value in Nm or in.lbs or kgf.cm directly on the
display of the control unit.
IMPORTANT: You need a torque tester to proceed, either with static transducer (model minik or K)
or with rotary transducer (model minik-e).
EXAMPLE: You have an application where you need 1.5 Nm and you would like to see, after each screw,
the torque value on the display of your EDU2AE/TOP (as you know all information you see on the display
can be printed out through the serial port thus helping you to keep trace of all fastening data). Let’s say you
are using a PLUTO6 screwdriver. Test the PLUTO6 on mini k5 torque tester and you find that you get
1.5Nm with the following parameters: Torque 25%, speed 920 RPM, SOFT Joint.
CALIBRATION PROCESS:
1. Select Calibration at point 23 of the menu and press OK.
2. The following screen will appear on the display:

WARNING:
- Calibration values will be referred to the parameters of the control unit which are set during
calibration, i.e. if you modify speed or type of joint, the unit will need to be recalibrated. During
calibration when a screwing is not carried out correctly or if for any reasons you’re not sure of the
torque value it is possible to repeat it. A wrong screwing can affect the precision of the calibration.
- Calibration is carried out for two torque levels optionally chosen. The minimum calibration interval
is 5% (example: if I have to work at 50%, I can calibrate at 45% and 55%). In this case, if for any
reasons I need to work at torque percentages which are lower or higher than the min-max ones set
during the calibration, they will be analyzed and displayed anyway but since they won’t be based on
effective data the torque value displayed may be not accurate.
- During calibration it is not possible to go back to the previous screen. Press ESC to stop calibration
and then repeat the screwing cycles.
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.

Page 15
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.
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.

Page 16
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.
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. 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 three beep sounds.
