Kolver EDU 2AE/TOP - Advanced Settings and Calibration

Manual EDU 2AE/TOP and EDU 2AE/TOP/TA Rev. 3 Page 7
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.
18) Press OK: when ON, press OK at the end of each screwing.
When OFF, the control unit resets automatically after a screwing.
19) Press ESC: when ON, press ESC to reset the control unit.
When OFF, the control unit resets automatically after an error signal
20) Reset: you can reset the program or the single screw.

21) Error lever: when ON, an error signal will occur when the lever has released before reaching the
torque.
When OFF, this function doesn’t work.
22) Defix allow: when OFF, the reverse is NOT enabled.
23) Calibration: When ON, you will see the torque value (Nm or in.lbs) on the main screen.
