5.6 CONTROL ELEMENTS
• The 'Incomplete Sequence' timer times out.
The recloser will be latched in the Lockout state until a 'Reset from lockout' signal is asserted, either from a manual close of
the breaker or from a manual reset command (local or remote). The reset from lockout can be accomplished by operator
command, by manually closing the breaker, or whenever the breaker has been closed and stays closed for a preset time.
After the dead time elapses, the scheme issues the close signal. The close signal is latched until the breaker closes or the
scheme goes to Lockout.
A reset timer output resets the recloser following a successful reclosure sequence. The reset time is based on the breaker
'reclaim time' which is the minimum time required between successive reclose sequences.
SETTINGS:
• AR1(2) INITIATE: Selects the FlexLogic™ operand that initiates the scheme, typically the trip signal from protection.
• AR1(2) BLOCK: Selects the FlexLogic™ operand that blocks the autoreclosure initiate (it could be from the breaker
failure, bus differential protection, etc.).
• AR1(2) MAX NUMBER OF SHOTS: Specifies the number of reclosures that can be attempted before reclosure goes
to "Lockout" because the fault is permanent.
• AR1(2) REDUCE MAX TO 1(3): Selects the FlexLogic™ operand that changes the maximum number of shots from
the initial setting to 1, 2, or 3, respectively.
• AR1(2) MANUAL CLOSE: Selects the logic input set when the breaker is manually closed.
• AR1(2) MNL RST FRM LO: Selects the FlexLogic™ operand that resets the autoreclosure from Lockout condition.
Typically this is a manual reset from lockout, local or remote.
• AR1(2) RESET LOCKOUT IF BREAKER CLOSED: This setting allows the autoreclose scheme to reset from Lockout
5 if the breaker has been manually closed and stays closed for a preset time. In order for this setting to be effective, the
next setting (
AR1(2) RESET LOCKOUT ON MANUAL CLOSE
• AR1(2) RESET LOCKOUT ON MANUAL CLOSE: This setting allows the autoreclose scheme to reset from Lockout
when the breaker is manually closed regardless if the breaker remains closed or not. This setting overrides the previ-
ous setting (
AR1 RESET LOCKOUT IF BREAKER CLOSED
• AR1(2) BLK TIME UPON MNL CLS: The autoreclose scheme can be disabled for a programmable time delay after
the associated circuit breaker is manually closed. This prevents reclosing onto a fault after a manual close. This delay
must be longer than the slowest expected trip from any protection not blocked after manual closing. If no overcurrent
trips occur after a manual close and this time expires, the autoreclose scheme is enabled.
• AR1(2) DEAD TIME 1 to AR1(2) DEAD TIME 4: These are the intentional delays before first, second, third, and fourth
breaker automatic reclosures (1st, 2nd, and 3rd shots), respectively, and should be set longer than the estimated
deionizing time following a three pole trip.
• AR1(2) ADD DELAY 1: This setting selects the FlexLogic™ operand that introduces an additional delay (Delay 1) to
the initial set Dead Time (1 to 4). When this setting is "Off", Delay 1 is by-passed.
• AR1(2) DELAY 1: This setting establishes the extent of the additional dead time Delay 1.
• AR1(2) ADD DELAY 2: This setting selects the FlexLogic™ operand that introduces an additional delay (Delay 2) to
the initial set Dead Time (1 to 4). When this setting is "Off", Delay 2 is by-passed.
• AR1(2) DELAY 2: This setting establishes the extent of the additional dead time Delay 2.
• AR1(2) RESET LOCKOUT DELAY: This setting establishes how long the breaker should stay closed after a manual
close command, in order for the autorecloser to reset from Lockout.
• AR1(2) RESET TIME: A reset timer output resets the recloser following a successful reclosure sequence. The setting
is based on the breaker 'reclaim time' which is the minimum time required between successive reclose sequences.
• AR1(2) INCOMPLETE SEQ TIME: This timer defines the maximum time interval allowed for a single reclose shot. It is
started whenever a reclosure is initiated and is active when the scheme is in the 'reclose-in-progress' state. If all condi-
tions allowing a breaker closure are not satisfied when this time expires, the scheme goes to "Lockout".
This timer must be set to a delay less than the reset timer.
