3. Adjusting the torque
The torque value of the screwdriver is adjusted by changing the tension of the
clutch spring, screwing or unscrewing the threaded #2 nut. After each adjustment
lock the nut by means of #30 ring.
To increase the torque turn the nut clockwise, to decrease it turn the nut
anticlockwise.
To change the spring remove #2 nut, replace the spring and then adjust the torque
value as mentioned above.
To check the torque value we suggest the use of K5 or MINI K5 electronic torque
tester.
4. Control unit and power supply
EDU 1FR power supply and control units act as voltage transformer and electronic
torque controller.
The power supply, 90/260VAC-50/60Hz, is converted into 18-30V DC required by
FAB and RAF series screwdrivers through an electronic transformer with constant
power of 120W. The electronic control circuit cuts the power supply to the motor
in response to the clutch action as soon as the pre-set torque has been reached.
On the front panel of the controller, there are two knobs indicated with the letters
“R” and “A”.
Knob “R” is used to adjust the slow start option (ramp) from 0 to 2 seconds, i.e. the
motor will reach the nominal speed gradually. Dial “1” for no ramp and “10” for
maximum ramp.
Knob “A” is used to adjust the motor speed for nominal speed, i.e. speed as per ctg.
data sheet, to 60% of nominal speed. Dial “1” for minimum speed and “10” for
nominal speed.
On the front panel you can also see 2 lights: the green one will light permanently
when the power is on, the red one will light only when the clutch “fires” indicating
the preset torque has been reached.
The temperature of the unit can normally reach 45°C.
On the back panel you can find a socket equipped with a fuse holder and on/off
switch. To replace the fuse just pull out the fuse holder and change the fuse.
