2.4 Automatic functions The apparatus control has inputs to be connected to automatic functions,
for example, slow autoreclose. When an automatic operation program
must take control of an apparatus, it must check if this is permitted. Auto-
matic 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 auto-
matic operation is permitted.
