Atlas Copco Power Focus 4000 Graph User Manual

The Power Focus offers several ways to control and monitor the
rundown of the screw cycle. The rundown is the rotation before snug
level (where the screw head starts compressing the joint).
Rundown Monitoring: monitor the angle between cutting the
fi rst thread and a settable torque level
PVT Selftap: monitor torque during an angle window
in the beginning of the rundown
PVT Monitoring: monitor torque during an angle window
somewhere within the rundown phase
PVT Compensate: compensate for torque lost to e.g. thread
forming during rundown, measured in
real-time for each individual screw
Post-view torque: a more fl exible strategy, allowing a max
torque for a settable window and a min
torque for another window to be defi ned
during rundown
