Parameter: 79 Ext Trip
•
Default Setting: <None>
See 7 Control Functions, section 79 Automatic Reclosing.
Parameter: 79 Ext Pickup
•
Default Setting: <None>
See 7 Control Functions, section 79 Automatic Reclosing.
Parameter: 79 Lockout
•
Default Setting: <None>
This is used to prevent autoreclosing by cancelling the sequence or preventing starting. This could be
used for unrecoverable conditions such as low gas (SF6) pressure etc, (see 7 Control Functions, section
79 Automatic Reclosing.
Parameter: 79 Reset Lockout
•
Default Setting: <None>
See 7 Control Functions, section 79 Automatic Reclosing.
Parameter: 79 SOTF
•
Default Setting: <None>
See 7 Control Functions, section 79 Automatic Reclosing.
Parameter: 79 Block Reclose
•
Default Setting: <None>
This is used to temporarily inhibit the CB close operation until conditions are correct. This is typically used
with different circuit‑breaker designs for signals such as spring charging or low air pressure
which can be cleared during the sequence allowing the sequence to continue. The Lockout input is
used for unrecoverable conditions such as low gas (SF6) pressure can be used to cancel an autoreclose
sequence or prevent starting, (see 7 Control Functions, section 79 Automatic Reclosing.
Parameter: Trigger I
2
t CB-n Wear
•
Default Setting: <None>
The I
2
t counter can be triggered from this input e.g. for a manually issued trip/open command, (see
7 Control Functions, section 52 Circuit-Breaker Control).
Parameter: Reset CB-n Trip Time
•
Default Setting: <None>
This resets the CB trip time instrument i.e. the measured time between the trip being issued and detec-
tion of the CB open state, (see 7 Control Functions, section 52 Circuit-Breaker Control).
