CONTROL ELEMENTS CHAPTER 5: SETTINGS
5
AR1 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 previous setting (
AR1
RESET LOCKOUT IF BREAKER CLOSED
).
AR1 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 DEAD TIME 1 to AR1 DEAD TIME 4 — These are the intentional delays before first, second, third, and fourth breaker
automatic reclosures (1st, 2nd, and 3rd shots), respectively. Set them longer than the estimated deionizing time following a
three pole trip.
AR1 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 DELAY 1 — This setting establishes the extent of the additional dead time Delay 1.
AR1 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 DELAY 2 — This setting establishes the extent of the additional dead time Delay 2.
AR1 RESET LOCKOUT DELAY — This setting establishes how long the breaker stays closed after a manual close command, in
order for the autorecloser to reset from Lockout.
AR1 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 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 conditions
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.
