WARNING:
-
Calibration values will be referred to the parameters of the control unit which are set during
calibration, i.e. if you modify speed or type of joint, the unit will need to be recalibrated. During
calibration when a screwing is not carried out correctly or if for any reasons
you’re not sure of the
torque value it is possible to repeat it. A wrong screwing can affect the precision of the calibration.
-
Calibration is carried out for two torque levels optionally chosen. The minimum calibration interval
is 5% (example: if I have to work at 50%, I can calibrate at 45% and 55%). In this case, if for any
reasons I need to work at torque percentages which are lower or higher than the min-max ones set
during the calibration, they will be analyzed and displayed anyway but since they won’t be based on
effective data the torque value displayed may be not accurate.
-
During calibration it is not possible to go back to the previous screen. Press ESC to stop calibration
and then repeat the screwing cycles.
USE OF T&A (Torque & Angle)
Choose the T & A mode (see point 26: 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 27). 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 op
erator: in fact the value is the result of an external impulse through a proper
co
ntact (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.
