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.
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 24) 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 which
is sufficiently higher than the threshold value (line 4), so that the set value is reached before the
screwdriver stops because of the reached torque.
