CHAPTER 5: SETTINGS
— Selects an operand that prevents initiation of Breaker 1 close commands. This setting can be used
BREAKER 1 BLK CLOSE
for blocking circuit breaker closing, for instance to prevent closing into a closed ground switch.
— Selects an operand, usually a contact input connected to a breaker auxiliary position tracking
BREAKER1 ΦA/3P CLSD
mechanism. This input is for a normally-open 52/a status input that creates a logic 1 when the breaker is closed. If the
setting is selected as "3-Pole," this setting selects a single 52/a input as the operand used to track the
BREAKER 1 MODE
breaker open or closed position. If the mode is selected as "1-Pole," the input mentioned is used to track phase A and the
and
BREAKER 1 ΦB
BREAKER 1 ΦC
— Selects an operand, usually a contact input, that is for a normally-closed 52/b status input that
BREAKER1 ΦA/3P OPND
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
— If the mode is selected as three-pole, this setting has no function. If the mode is selected as single-
BREAKER 1 ΦB CLOSED
pole, this input is used to track the breaker phase B closed position as outlined for phase A.
— If the mode is selected as three-pole, this setting has no function. If the mode is selected as single-
BREAKER 1 ΦB OPENED
pole, this input is used to track the breaker phase B opened position as outlined for phase A.
— If the mode is selected as three-pole, this setting has no function. If the mode is selected as single-
BREAKER 1 ΦC CLOSED
pole, this input is used to track the breaker phase C closed position as outlined for phase A.
— If the mode is selected as three-pole, this setting has no function. If the mode is selected as single-
BREAKER 1 ΦC OPENED
pole, this input is used to track the breaker phase C opened position as outlined for phase A.
— This setting specifies the required interval to overcome transient disagreement between the 52/a
BREAKER 1 TOPERATE
and 52/b auxiliary contacts during breaker operation. If transient disagreement still exists after this time has expired, the
FlexLogic operand is asserted for alarm or blocking purposes.
BREAKER 1 BAD STATUS
— This setting selects an operand, usually an external contact input connected to a breaker alarm
BREAKER 1 EXT ALARM
reporting contact. While the selected operand is active, the
— This setting specifies the delay interval during which a disagreement of status among the three-
BREAKER 1 ALARM DELAY
pole position tracking operands does not declare a pole disagreement. This allows for non-simultaneous operation of the
poles.
— This setting specifies the seal-in time of the three-pole open command initiated by either the
BREAKER 1 OPEN SEAL-IN
Trip Out element or a manual open command to the circuit breaker.
— This setting specifies the seal-in time of the close commands due to an operator-initiated
MANUAL CLOSE RECAL1 TIME
manual close command to the circuit breaker.
— Selects an operand indicating that breaker 1 is out-of-service.
BREAKER 1 OUT OF SV
— This setting selects a contact input to show whether the breaker is racked-in or racked-out. The
BREAKER 1 RACKED-IN
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.
IEC 61850 functionality is permitted when the C60 device is in "Programmed" mode and not in local control mode.
