Use of a NO/ NC combination
As a general principle, use both NO contacts as switching outputs!
To configure machine contactors this means connecting a
contactor at each NO output!
If a combination of NO and NC contacts is used as safety
switching outputs, both NO contacts must be connected in series.
The function of the contactors must be tested by use of external
device monitor T
