FQM end stops limit the swing angle. They are used as limit switches and protect
the valve in the event of a fail safe operation.
No end stops are provided within the AUMA part-turn actuator when combined with
an FQM. The end stops of the fail safe unit exclusively limit the swing angle.
The swing angle set in the factory is indicated on the name plate of the fail safe unit.

The setting sequence depends on the application. As a general rule, the end position
of the fail safe function (fail safe position) is set first.
