# Configuration of the Open End

Before using an open end tool, make sure that the tool head and tool body have been assembled and configured correctly. If not, the tool can run in the wrong direction and the mechanical stop in the open-end head may be damaged.

After performing a tightening with an open end tool, it is possible to let the open end tool getting to the opening position again through the open end configuration.

Configure the open end strategies and settings through the HMI (Human Machine Interface).

The open end configuration is applicable only to cable tools, IXB tools, and STB tools.
The open end configuration is not applicable to Flex and to synchronized tightening.

Automatic Positioning | After performing a tightening with an open end tool, it is possible to let the open end tool getting to the opening position again automatically. A toggle key turns the Automatic Positioning On or Off: On: if enabled, after the tightening, when the open end tool is lifted up, the open end tool gets to the opening position again automatically. The operator must hold down the tool trigger during the full process (tightening + Automatic Positioning). If the operator releases the tool trigger before that the Automatic Positioning is completed, the open end tool will get back to the opening position through the selected Positioning Strategy. Off: default value. If disabled, after the tightening, when the open end tool is lifted up, the open end tool does not get to the opening position again automatically. When the open end tool is lifted up, the operator must release the tool trigger. To let the open end tool getting to the opening position again, the operator must hold down the tool trigger again during the full Automatic Positioning. Automatic Positioning is applicable only to Multistep tightening programs. Automatic Positioning is applicable only to cable tools and IXB tools.
Positioning Strategy | Select the Positioning Strategy to let the open end tool getting back to the opening position after the tightening. Forward: default value. The open end tool turns forward - in the same direction of the tightening direction - to the opening position. Reverse: the open end tool turns reverse - in the opposite direction of the tightening direction - to the opening position. Reverse Torque Based: the open end tool gets to the opening position through a slow reverse rotation that is done by reversing slowly and monitoring the torque. Forward Fast Start: the open end tool gets to the opening position as quick as possible. We recommend to use Reverse Torque Based and Forward Fast Start strategies for open end tools with swiveling front part. Reverse Torque Based and Forward Fast Start strategies are applicable only to cable tools and IXB tools. If the Positioning Strategy of the STB tools is Reverse Torque Based or Forward Fast Start, the default Positioning Strategy would run automatically. For Reverse Torque Based, the default Positioning Strategy is Reverse. For Forward Fast Start, the default Positioning Strategy is Forward.
Positioning Speed | Positioning Speed defines how quickly the tool should get to the opening position. Positioning Speed is expressed as the percentage (%) of the open end tool maximum speed. The operator can enter a Positioning Speed value which ranges from 5% through 100%. By default, the Positioning Speed is set to 38%.
