Abstract
A powered driver and methods are disclosed, the driver including a head having a gapped jaw and housing a motor driven drive transfer assembly for operating a rotatable split socket engageable at a threaded connector. A reaction unit is movably maintained through the head, and a probe is associated with the reaction unit. The methods of this invention include setting a selected rotational limitation at the driver relating to fitting characteristics, operating the driver to cause relative rotation of a connector nut located in the socket and connector body engaged by the reaction unit. One of a plurality of operational modes for driver operations is selected and relative movement of the head and reaction unit are monitored during driver operation. The driver is controlled so that driver operation ceases when a selected combination of events related to operational mode selected and at least one of rotational limitation setting, monitored relative movement or driver operation occurs.
