5-118 N60 NETWORK STABILITY AND SYNCHROPHASOR MEASUREMENT SYSTEM – INSTRUCTION MANUALSYSTEM SETUP CHAPTER 5: SETTINGS5A description of the operation of the breaker control and status monitoring features is provided in chapter 4. Information toprogram the settings is covered here. These features are provided for two or more breakers; a user can use only thoseportions 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 N60. The followingsettings 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 pushbutton operations.BREAKER 1 NAME — Assign a user-defined name (up to six characters) to the breaker. This name is used in flash messagesrelated to breaker 1.BREAKER 1 MODE — Selects “3-Pole” mode, where all breaker poles are operated simultaneously, or “1-Pole” mode where allbreaker poles are operated either independently or simultaneously.BREAKER 1 OPEN — Selects an operand that creates a programmable signal to operate an output relay to open breaker 1.BREAKER 1 BLK OPEN — 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 — Selects an operand that creates a programmable signal to operate an output relay to close breaker 1.BREAKER 1 BLK CLOSE — 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 A/3P CLOSED — Selects an operand, usually a contact input connected to a breaker auxiliary position trackingmechanism. This input is a normally-open 52/a status input to create a logic 1 when the breaker is closed. If the BREAKER 1MODE setting is selected as “3-Pole,” this setting selects a single input as the operand used to track the breaker open orclosed position. If the mode is selected as “1-Pole,” the input mentioned is used to track phase A and the BREAKER 1 B andBREAKER 1 C settings select operands to track phases B and C, respectively.
