P/F Shots Sub-Menu; E/F Shots Sub-Menu; Sef Shots Sub-Menu; Extern Shots Sub-Menu - Siemens 7SR10 Argus Series Manual

If the Lockout command is received while a Manual Close operation is in progress, the feature is immediately
locked-out.
Once the Lockout condition has been reached, it will be maintained until reset. The following will reset lockout: -
• By a Manual Close command, from fascia, comms or Close CB binary input.
By a 79 Reset Lockout binary input, provided there is no signal present that will cause
•
Lockout.
• At the end of the 79 Minimum LO Delay time setting if 79 Reset LO by Timer is selected to
ENABLED, provided there is no signal present which will cause Lockout.
• Where Lockout was entered by an A/R Out signal during an Autoreclose sequence then a 79
In signal must be received before Lockout can reset.
• By the CB Closed binary input, provided there is no signal present which will cause Lockout.
The Lockout condition has a delayed drop-off of 2s. The Lockout condition can not be reset if there is an active
lockout input.

P/F Shots sub-menu

4.1.5
This menu allows the Phase fault trip/reclose sequence to be parameterized:-
79 P/F Prot'n Trip1
79 P/F Deadtime 1
79 P/F Prot'n Trip2
79 P/F Deadtime 2
79 P/F Prot'n Trip3
79 P/F Deadtime 3
79 P/F Prot'n Trip 4
79 P/F Deadtime 4
79 P/F Prot'n Trip5
79 P/F HighSet Trips to Lockout Sets the number of allowed HighSet trips. The relay will go to Lockout on the
79 P/F Delayed Trips to Lockout Sets the number of allowed Delayed trips, Relay will go to Lockout on the last

E/F Shots sub-menu

4.1.6
This menu allows the Earth Fault trip/reclose sequence to be parameterized:-
As above but E/F settings.

SEF Shots sub-menu

4.1.7
This menu allows the Sensitive Earth trip/reclose sequence to be parameterized:-
As above but SEF Settings, Note: - SEF does not have HighSets

Extern Shots sub-menu

4.1.8
This menu allows the External Protection auto-reclose sequence to be parameterized:-
79 P/F Prot'n Trip1
79 P/F Deadtime 1

The first protection Trip in the P/F sequence can be set to either Inst or Delayed.
Sets the first Reclose Delay (Dead time) in the P/F sequence.
The second protection Trip in the P/F sequence can be set to either Inst or Delayed.
Sets the second Reclose Delay (Dead time) in the P/F sequence.
The third protection Trip in the P/F sequence can be set to either Inst or Delayed.
Sets the third Reclose Delay (Dead time) in the P/F sequence.
The fourth protection Trip in the P/F sequence can be set to either Inst or Delayed.
Sets the fourth Reclose Delay (Dead time) in the P/F sequence.
The fifth and last protection Trip in the P/F sequence can be set to either Inst or
Delayed.
last HighSet Trip. This function can be used to limit the duration and number of high
current trips that the Circuit Breaker is required to perform, if the fault is permanent
and close to the Circuit Breaker then there is no point in forcing a number of Delayed
Trips before the Relay goes to Lockout – that sequence will be truncated.
Delayed Trip. This function limits the number of Delayed trips that the Relay can
perform when the Instantaneous protection Elements are externally inhibited for
system operating reasons - sequences are truncated.
Not Blocked/Blocked - Blocked raises an output which can be mapped to a Binary
output to Block an External Protection's Trip Output.
Sets the first Reclose Delay (Deadtime) for the External sequence.
