# Source Tightening

The tightening menu shows a list of source tightening configurations. To link separate lists to a virtual station, go to the Virtual Station tab, select the virtual station in question on the left pane and, on the Task window, select Choose task. There, a Source can be chosen as a task. Source tightenings link a specific tightening program to an identifier number. When the identifier number is sent to the controller (either by external digital signal, or, in cases where a socket selector is used, by lifting the corresponding socket in the selector) the linked program will run according to the source tightening configuration. It can either run repeatedly, or as a batch with a batch size configured either in the source tightening list or set dynamically by an external system.

Source Tightening lists can be set either in Control or Confirm mode.

- In Control mode, an external source selects a tightening program by requesting an identifier number. In case of a socket selector, the identifier number is linked to a corresponding socket in the socket selector, and the tightening program is selected by lifting the socket.

- In Confirm mode, the socket selector cannot be used as a controlling source. In this mode identifier numbers are linked to both a tightening program and a specific socket (indicated in an additional column in the list). When an identifier number is requested (by an external signal), the corresponding socket is prompted in the socket selector and the tightening program is activated when the operator lifts the socket (other sockets are disabled). If no socket is specified (that is, set to 0 in the Socket column), the tightening program is activated directly and the socket status is ignored.

POWER FOCUS 8 can store up to 250 sources.
