5 SETTINGS
must be programmed to create a logic 0 when the breaker is open. If
ting selects a single input as the operand 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 settings
operands to track phases B and C, respectively.
• BREAKER 1(2) FB: If the mode is selected as 3-pole, this setting has no function. If the mode is selected as 1-pole,
this input is used to track phase B as above for phase A.
• BREAKER 1(2) FC: If the mode is selected as 3-pole, this setting has no function. If the mode is selected as 1-pole,
this input is used to track phase C as above for phase A.
• BREAKER 1(2) EXT ALARM: Selects an operand, usually an external contact input, connected to a breaker alarm
reporting contact.
• BREAKER 1(2) ALARM DELAY: Sets the delay interval during which a disagreement of status among the three pole
position tracking operands will not declare a pole disagreement, to allow for non-simultaneous operation of the poles.
• MANUAL CLOSE RECAL1 TIME: Sets 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(2) OUT OF SV: Selects an operand indicating that Breaker 1(2) is out-of-service.
• XCBR ST.LOC OPERAND: Selects a FlexLogic™ operand to provide a value for the IEC 61850 XCBR1(2) St.Loc
data item.
