7-537SA6 Manual
C53000-G1176-C133-1
The Interlock display has an object table similar to the one described for Set Status.
The table provides the set interlocking conditions, which prevent, or could prevent, a
local control operation. Letters identify the interlocking conditions. The meanings of
the letters are:
• L Local/Remote (Switching Authority),
• S Equipment is subject to System Interlocking (in Substation Controller).
Commands entered locally are sent to the central computer or controller,
• Z Zone controlled (Field- or Bay-Interlocking),
• P Check switch position (test actual vs. scheduled),
• B Blocking by picked-up protection elements,
• – Non-Interlocked.
