Minimum Time; Maximum Time - Kolver EDU2AE Manual

4)
Brake time: This parameter is only active in combination with the option JOINT: HARD. Break Time
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
many times as needed. In this case the screwdriver will automatically start at pre-torque speed (lower
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. Reach -
ing 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 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.
5) 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 final torque during the ramp time will likely result in a different (lower) torque
level from the one that results when the tool is at full speed (due to the motor acceleration). Even so; the
"Screw OK" signal will activate when reaching final torque during the ramp time, allowing for tightening
screws that are already tightened, the so called "double hit". If you wish to disable this function and see a
error signal during the ramp phase, you can change the minimum time by setting value which is equal or
greater to the ramp time value (see point 7).

6) Speed:
You can select any speed value of the screwdriver between the maximum & minimum speed
specified in the catalog (see table with technical data). Note that all the torque specification provided
assume the tool is set at its maximum speed.

7) Minimum Time:

You can set this time from 0,1s to 'Max time - 0.1s'. To disable the function select OFF by pressing
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.

8) Maximum time:

You can set this time from 'Min time + 0,1s' to 20,0s
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.
