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.

ATTENTION: The pre-set torque level in % and in Nm for PLUTO3FR, PLUTO5FR o PLUTO7FR models

doesn’t appear on the display. Moreover, some settings will be unchangeable, so if you try to modify such

settings the following line will be displayed: “not available for clutch”.

4) Torque level: 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 on hard joint 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 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

U

only

U

in 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 s.

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 we

suggest selecting a shorter time, and then increase it step by step until the optimum time is found.

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 e EDU 2AE/TOP/TA Rev.0 Pagina 6

7) Ramp time: You can select the slow start time (acceleration) from 0.2 to 3.00 seconds. This option is

only available for the screwing phase, while during the unscrewing phase the ramp time is always 0.2

seconds. 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 0,1s 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 tightening time. You can set from 'Min

time + 0,1s' to 20,0s.

ATTENTION: If torque isn’t reached within 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 20.0s.

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

nominal (maximum speed given in the catalogue) and the minimum speed of every single screwdriver (see

table with technical data).

Manual EDU 2AE/TOP e EDU 2AE/TOP/TA Rev.0 Pagina 7

13) 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.

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 0.1s to 10.0s. 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 trilobe 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.

and release it before reaching the torque. Set OFF in you don't want this feature.

19) Defix allow: Set ON if you want the reverse switch on the PLUTO to work normally. Set OFF if you

want the screwdriver to work only forward, i.e. the reverse switch will not work.

20) Calibration: Set ON to see the torque value (Nm or lb.in) on the main screen. Set OFF if you

don't want the torque value to be displayed.

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

after calibration. The available range is from 0 to ±9,99Nm. 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 model). Let's say you notice

that the torque displayed in the unit EDU 2AE/HP is +0.2Nm higher than the value indicated on the tester

(which is the right one). In this case you change this value by setting -0,2Nm so that the value on the screen

will be the same as the value on the tester. If it’s lower than 0.3Nm, you need to set +0.3Nm and so on.

22) Unit: You can choose between the following units of measurements: Nm and lb.in.

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 Nm 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 0Nm.

TORQUE CALIBRATION

It is necessary to have a torque tester to proceed with the torque calibration operation. Please read the

instructions carefully.

The torque calibration function allows to view the torque value in Nm or lb.in 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 2% (example: if I have to work at 30%, I can calibrate at 29% and 31%) but we recommend a

minimum of 10% interval.

−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.

Manual EDU 2AE/TOP e EDU 2AE/TOP/TA Rev.0 Pagina 12

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.

Manual EDU 2AE/TOP e EDU 2AE/TOP/TA Rev.0 Pagina 13

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.

TORQUE/INPUT (T/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.

Manual EDU 2AE/TOP e EDU 2AE/TOP/TA Rev.0 Pagina 14

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 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.
