6.8.2.3 Residual Peak/Torque
This strategy evaluates the residual torque on a joint as the peak of the torque necessary to rotate the
screw further. The result of this strategy is affected by operator movement; it is important to release
the torque as soon as the screw starts moving.
Specify the
Cycle start and the Torque limits .
Furthermore, it is MANDATORY to set a
Change Screw value: if the operator goes over this value, a
message is shown on the Delta Wrench display to indicate that the screw must be replaced with a
new one.
The Delta Wrench display background is colored as follows:
Blue Default color used for Pset execution.
Green
The display turns green if the torque peak is between the minimum and maximum
torque.
Red
The display turns red if the torque peak is below the minimum or over the
maximum torque.
The buzzer is activated as follows:
Buzzer The beep emitted by the buzzer starts when the torque goes over the Cycle Start
value.

end of the operation; if the result is
Not OK , the last beep remains active to
indicate the error, and it is reset when either the OK or CL button is pressed.
