# Source Tightening Properties

Parameter | Description
--- | ---
Name | The name issued to the source tightening.
Selector mode | Control mode: An external source selects a tightening program by requesting an identifier number. The identifier number is linked to a corresponding socket in the socket selector, and by lifting the socket the tightening program is selected 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.
Max consecutive NOK per program | On: The batch will advance even if a NOK tightening is performed. Off: Set Max consecutive NOK for the tightening. The batch will only advance if a successful tightening is performed.
Max consecutive NOK | Set the number of consecutive NOK results to be allowed. If the value is set to 0, there is no check performed for NOK tightenings. When reaching max consecutive NOK, the tool locks and the sequence execution is halted.
Batch control | Select how the source tightening is to be executed. Internal: Configure how many times a source tightening is to be repeated. External: Configure how many times a source tightening should be executed by using Open protocol or an external protocol. Any configuration change clears the source tightening to start over from a clean and known state (the batch count in the batch will be reset to 0). Ongoing tightenings are able to finish before the changes take effect.
