CONTROL ELEMENTS
306
Select Time
Range: 1.0 to 30.0 seconds in steps of 0.1
Default: 5 seconds
This setting determines the maximum permissible time from selection of autoreclose
and a control action.
Maximum Number of Shots
Range: 1, 2, 3, 4
Default: 2
This setting specifies the number of reclosures attempted before reclosure goes to
lockout when the fault is permanent.
Block Breaker 1
Range: any FlexLogic™ operand or shared operand
Default: Off
This setting selects an operand that will block the reclose command for breaker 1. This
condition can include breaker low air pressure, reclose in progress on another line (for
the central breaker in a breaker and a half arrangement), or a sum of conditions
combined in FlexLogic™.
Close Time Breaker 1
Range: 0.00 to 655.35 seconds in steps of 0.01
Default: 0.10 seconds
This setting represents the closing time for breaker 1 from the moment the
command is sent to the moment the contacts are closed.
Breaker Manual Close
Range: any FlexLogic™ operand or shared operand
Default: Off
This setting selects an operand that represents a manual close command to a breaker
associated with the autoreclose scheme.
Block Time Upon Manual Close
Range: 0.00 to 655.35 seconds in steps of 0.01
Default: 10.00 seconds
The autoreclose scheme can be disabled for a programmable time delay after an
associated circuit breaker is manually commanded to close, preventing reclosing onto
an existing fault such as grounds on the line. This delay must be longer than the slowest
expected trip from any protection not blocked after manual closing. If the autoreclose
scheme is not initiated after a manual close and this time expires, the autoreclose
scheme is set to the reset state.
1-Pole Initiate
Range: any FlexLogic™ operand or shared operand
Default: Off
This setting selects an operand used to initiate single-pole autoreclosure.
3-Pole Initiate
Range: any FlexLogic™ operand or shared operand
Default: Off
This setting selects an operand used to initiate three-pole autoreclosure. The first timer
( ) can be used for a high-speed autoreclosure.
