USE OF T&A (Torque & Angle)
Choose the T & A mode (see point 29: Modify function on the program menu)
It is possible to set 6 different modes:
TORQUE (Torque): It’s the most common use mode. The control unit shows the tightening torque and
the torque starting from a certain torque percentage (threshold torque, see point 30). If the final torque
and angle values are within the preset minimum and maximum values, the screw is correctly tightened. If
the torque and/or angle are outside the preset values, the screw will be considered as incorrectly tightened.
In this case the red led will light up and the message “
Error Max (Min) Angle
” or “
Error Max (Min)
Torque
” will be displayed.
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.
