The apparatus control has inputs to be connected to automatic functions, for example,
delayed autoreclosing. When an automatic operation program must take control of an
apparatus, it must check if this is permitted. Automatic operations are permitted when
these conditions are fulfilled:
•
Operator place is not local
•
The apparatus is not selected
•
The apparatus is not reserved
•
The concerned apparatus is not blocked for operation
•
Position indications are not blocked
The function, which operates automatically, also first determines if automatic operation
is permitted.
