BREAKER 1 NAME
— Assign a user-defined name (up to six characters) to the breaker. This name is used in flash messages
related to breaker 1.
BREAKER 1 MODE
— Selects “3-Pole” mode, where all breaker poles are operated simultaneously, or “1-Pole” mode where all
breaker poles are operated either independently or simultaneously.
BREAKER 1 OPEN
— Selects an operand that when activated, and unless blocked, initiates the Breaker 1 open and individual
phase trip commands.
BREAKER 1 BLK OPEN
— Selects an operand that prevents initiation of Breaker 1 open and individual phase trip commands.
This setting can be used for blocking circuit breaker tripping for instance when breaker monitoring detects conditions such
as low SF
6
gas density during which breaker opening can cause damage.
BREAKER 1 CLOSE
— Selects an operand that when activated, and unless blocked, initiates the Breaker 1 close commands.
BREAKER 1 BLK CLOSE
— Selects an operand that prevents initiation of Breaker 1 close commands. This setting can be used
for blocking circuit breaker closing, for instance to prevent closing into a closed ground switch.
BREAKER1
Φ
A/3P CLSD
— Selects an operand, usually a contact input connected to a breaker auxiliary position tracking
mechanism. This input is for a normally-open 52/a status input that creates a logic 1 when the breaker is closed. If the
BREAKER 1 MODE
setting is selected as "3-Pole," this setting selects a single 52/a input as the operand used to track the
breaker open or closed position. If the mode is selected as "1-Pole," the input mentioned is used to track phase A and the
BREAKER 1
Φ
B
and
BREAKER 1
Φ
C
settings select operands to track phases B and C, respectively.
BREAKER1
Φ
A/3P OPND
— Selects an operand, usually a contact input, that is for a normally-closed 52/b status input that
creates a logic 1 when the breaker is open. If a separate 52/b contact input is not available, then the inverted 52/a status
signal or the inverted
BREAKER 1 CLOSED
status signal can be used.
BREAKER 1
Φ
B CLOSED
— If the mode is selected as three-pole, this setting has no function. If the mode is selected as single-
pole, this input is used to track the breaker phase B closed position as outlined for phase A.
BREAKER 1
Φ
B OPENED
— If the mode is selected as three-pole, this setting has no function. If the mode is selected as single-
pole, this input is used to track the breaker phase B opened position as outlined for phase A.
BREAKER 1
Φ
C CLOSED
— If the mode is selected as three-pole, this setting has no function. If the mode is selected as single-
pole, this input is used to track the breaker phase C closed position as outlined for phase A.
BREAKER 1
Φ
C OPENED
— If the mode is selected as three-pole, this setting has no function. If the mode is selected as single-
pole, this input is used to track the breaker phase C opened position as outlined for phase A.
BREAKER 1 TOPERATE
— This setting specifies the required interval to overcome transient disagreement between the 52/a
and 52/b auxiliary contacts during breaker operation. If transient disagreement still exists after this time has expired, the
BREAKER 1 BAD STATUS
FlexLogic operand is asserted for alarm or blocking purposes.
BREAKER 1 EXT ALARM
— This setting selects an operand, usually an external contact input connected to a breaker alarm
reporting contact. While the selected operand is active, the
BREAKER 1 TROUBLE
operand is activated.
BREAKER 1 ALARM DELAY
— This setting specifies the delay interval during which a disagreement of status among the three-
pole position tracking operands does not declare a pole disagreement. This allows for non-simultaneous operation of the
poles.
BREAKER 1 OPEN SEAL-IN
— This setting specifies the seal-in time of the three-pole open command initiated by either the
Trip Out element or a manual open command to the circuit breaker.
MANUAL CLOSE RECAL1 TIME
— This setting specifies the seal-in time of the close commands due to an operator-initiated
manual close command to the circuit breaker.
BREAKER 1 OUT OF SV
— Selects an operand indicating that breaker 1 is out-of-service.
BREAKER 1 RACKED-IN
— This setting selects a contact input to show whether the breaker is racked-in or racked-out. The
racked-in or racked-out status is used to indicate dynamically the status of breaker symbol, only applied in the single-line
diagram in the graphical front panel. If this setting is set to Off, the racked status is not considered.
