Reset
The dangerous state of the machine ( ) is interrupted if the light path is broken ( ), and

Do not confuse reset and the restart interlock with the starting interlock on the machine.

restart interlock prevent the machine starting again after an error or an interruption of the
light path.
You can only implement a restart interlock via an external machine restart interlock:
The miniTwin2 has no control over the restart.
You can implement a reset using the Reset function on the miniTwin2:
The miniTwin2 controls the machine start.
Ensure on the usage of the Reset function that an erroneous start-up cannot result in a
dangerous situation!
