A description of the operation of the breaker control and status monitoring features is provided in chapter 4. Only informa-
tion concerning programming of the associated settings is covered here. These features are provided for two or more
breakers; a user may use only those portions of the design relevant to a single breaker, which must be breaker 1.
The number of breaker control elements is dependent on the number of CT/VT modules specified with the G60. The follow-
ing settings are available for each breaker control element.
• BREAKER 1 FUNCTION: This setting enables and disables the operation of the breaker control feature.
• BREAKER1 PUSH BUTTON CONTROL: Set to “Enable” to allow faceplate push button operations.
• BREAKER 1 NAME: Assign a user-defined name (up to six characters) to the breaker. This name will be used in flash
messages related to breaker 1.
• BREAKER 1 MODE: This setting 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: This setting selects an operand that creates a programmable signal to operate an output relay to
open breaker 1.
• BREAKER 1 BLK OPEN : This setting selects an operand that prevents opening of the breaker. This setting can be
used for select-before-operate functionality or to block operation from a panel switch or from SCADA.
• BREAKER 1 CLOSE: This setting selects an operand that creates a programmable signal to operate an output relay
to close breaker 1.
• BREAKER 1 BLK CLOSE : This setting selects an operand that prevents closing of the breaker. This setting can be
used for select-before-operate functionality or to block operation from a panel switch or from SCADA.
• BREAKER 1
Φ
A/3P CLOSED: This setting selects an operand, usually a contact input connected to a breaker auxil-
iary position tracking mechanism. This input should be a normally-open 52/a status input to create a logic 1 when the
breaker is closed. If the
BREAKER 1 MODE
setting is selected as “3-Pole”, this setting selects a single input as the oper-
and used to track the breaker open or closed position. If the mode is selected as “1-Pole”, the input mentioned above
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.
• BREAKER 1
Φ
A/3P OPND: This setting selects an operand, usually a contact input, that should be a normally-closed
52/b status input to create a logic 1 when the breaker is open. If a separate 52/b contact input is not available, then 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 above 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 above 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 above 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 above 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 from 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.
• BREAKER 1 ALARM DELAY: This setting specifies the delay interval during which a disagreement of status among
the three-pole position tracking operands will not declare a pole disagreement. This allows for non-simultaneous oper-
ation of the poles.
• MANUAL CLOSE RECAL1 TIME: This setting specifies the interval required to maintain setting changes in effect after
an operator has initiated a manual close command to operate a circuit breaker.
• BREAKER 1 OUT OF SV: Selects an operand indicating that breaker 1 is out-of-service.
