5.5. Slow start
The slow start option can be adjusted between
0.2 and 2 seconds.
This option is mostly used in the self-tapping
screw cases.
If the torque is reached during this phase, less
acurate tightening torques may result from it.
If the torque has been reached during this
phase, a NOK message is displayed on the
screen with 3 audible sounds.
The output signals "ERROR" and "TORQUE"
will be transmitted simultaneously.

5.6. Speed
You can choose a speed value included between
30 % and 100 % of the rated speed of the tool
(see 5.3).
The torque range is valid only for the
rated speed given for each screwdriver.
If you need to choose a slower speed than the
authorised speed, check that the screwdriver
stops correctly at the selected torque.
Also see 5.4 (approach time) for the speed
adjustment on hard joints.
5.7. Elapsed time
You can choose a time included between 0
second (the function is not actuated) and 10
seconds.
This option can be used for two main reasons:
● In the event that you would like to stop
screwdriver at a given depth or time.
● In the event that you would like to detect a
damaged thread or a missing screw (with a
spindle application for example).
If the pre-adjusted time has elapsed without
having reached the torque, a NOK message is
displayed on the screed and an "ERROR" output
signal is transmitted.
5.8. Run reverse time
By selecting this option, the screwdriver will
automatically start an untightening cycle after
having detected a " TORQUE" or an " ERROR"
signal (see 5.7).
You can choose a time included between OFF
(function excluded) and 10 seconds.
During the untightening cycle, it is important
to maintain the lever pressed or to maintain
the input "START" signal to make sure the
screwdriver stops at the end of the adjusted
untightening time.
