Allowing a disabled tool to unlock after loosening

  1. In the configuration used by the tool (set in the Virtual Station the tool is connected to), set the Unlock tool on loosening to On OK or Always.

    In order to enable the setting above, three conditions need to be met:

    1. The Disable loosening parameter cannot be set to Off or Always.

    2. The Disable loosening value cannot be set to the same value as the Disable tightening.

    3. The tightening program used must have loosening enabled.

When the tool is locked for either tightening or loosening due to a disable state, it can be unlocked by any of the following input signals:

  • Master_Unlock

  • Unlock_Tool_On_Disable

This input signal can be sent to the controller either from an accessory, from a programable tool accessory, or from the Fieldbus unit.
