tubenut tool to the home position on every other trigger pull. The resolver integrated into the
nutrunner measures the angle during the untightening. The value is processed by the control
system. When the Turnoff angle is reached the nutrunner is shut off. For a tubenut tool, the Turn-
off angle is programmed so that the attachment will always turn far enough to reach the home
position and stop based on the torque reaction against the pawl.

Parameters are programmable for a given Tool, Application and Stage based on the selected
Fastening Sequence and only the appropriate parameters are displayed for the selected Fasten-
ing Sequence.
The Next Stage <F2> key will increment to the next stage until it reaches the last stage having a
selected Sequence. It will then rollover to the first stage. In order to add a stage without a
selected Sequence the user must highlight the stage field and enter a number 1-6.
The following is a detailed description of each Fastening Sequence and associated Parameters:
Sequence 11
High Speed Rundown
This tightening method is generally used as a fast pre-tightening stage. The torque transducer
integrated into the nutrunner measures the torque during the tightening. The value is processed
by the control system. When the defined Turnoff Torque is reached the nutrunner is shut off.
Thereafter the peak torque is measured during a dwell time and is then processed as the tighten-
ing torque of the bolt in the control system. This value is displayed on the Run Screen and can be
output to a printer or transmitted to other system components by data communication. When the
trigger torque is reached the torque curve is recorded and can be viewed and evaluated using
the oscilloscope function.
