Multistep Tightening Strategy

A multistep tightening is a tightening done in several steps. The number of steps and the type of the steps vary depending on the tightening to be done. A multistep tightening program is highly configurable, including monitoring functions and restrictions. A total of 16 steps can be added to a multistep program.

Restrictions are used to make sure the tightening stops if something unexpected occurs. These restrictions could, for example, test that a maximum set torque is not reached or that a part of the multistep tightening does not take too long to run. Every step can have up to four restrictions each. Each step has mandatory step restrictions and optional step restrictions. The mandatory restrictions are included when dragging a new step to the multistep program.

Monitors are used to verify that the tightening was made according to the specification. This can be, for example, angle limits or torque limits. Every step can have up to eight monitors each. Each step has mandatory step monitors and optional step monitors. The mandatory monitors are included when dragging a new step to the multistep program.
