CHAPTER 5: SETTINGS
A description of the operation of the breaker control and status monitoring features is provided in chapter 4. Information to
program the settings is covered here. These features are provided for two or more breakers; a user can use only those
portions of the design relevant to a single breaker, which must be breaker 1.
The number of breaker control elements depends on the number of CT/VT modules specified with the C30. The following
settings are available for each breaker control element.
— This setting enables and disables the operation of the breaker control feature.
BREAKER 1 FUNCTION
BREAKER1 PUSH BUTTON CONTROL
— Assign a user-defined name (up to six characters) to the breaker. This name is used in flash messages
BREAKER 1 NAME
related to breaker 1.
— Selects "3-Pole" mode, where all breaker poles are operated simultaneously, or "1-Pole" mode where all
BREAKER 1 MODE
breaker poles are operated either independently or simultaneously.
— Selects an operand that creates a programmable signal to operate an output relay to open breaker 1.
BREAKER 1 OPEN
— Selects an operand that prevents opening of the breaker. This setting can be used for select-before-
BREAKER 1 BLK OPEN
operate functionality or to block operation from a panel switch or from SCADA.
— Selects an operand that creates a programmable signal to operate an output relay to close breaker 1.
BREAKER 1 CLOSE
— Selects an operand that prevents closing of the breaker. This setting can be used for select-before-
BREAKER 1 BLK CLOSE
operate functionality or to block operation from a panel switch or from SCADA.
— Selects an operand, usually a contact input connected to a breaker auxiliary position tracking
BREAKER 1 ΦA/3P CLOSED
mechanism. This input is a normally-open 52/a status input to create a logic 1 when the breaker is closed. If the
setting is selected as "3-Pole," this setting selects a single input as the operand used to track the breaker open or
MODE
closed position. If the mode is selected as "1-Pole," the input mentioned is used to track phase A and the
settings select operands to track phases B and C, respectively.
BREAKER 1 ΦC
— Selects an operand, usually a contact input, that is a normally-closed 52/b status input to create
BREAKER 1 ΦA/3P OPND
a logic 1 when the breaker is open. If a separate 52/b contact input is not available, then the inverted
signal can be used.
— 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 from 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.
— 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 interval required to maintain setting changes in effect after an
MANUAL CLOSE RECAL1 TIME
operator has initiated a manual close command to operate a circuit breaker.
— Selects an operand indicating that breaker 1 is out-of-service.
