GE Multilin L90 Line Differential Relay 5-455 SETTINGS 5.3 SYSTEM SETUP5must be programmed to create a logic 0 when the breaker is open. If BREAKER 1 MODE is selected as "3-Pole", this set-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 BREAKER 1 ΦB and BREAKER 1 ΦC selectoperands to track phases B and C, respectively.ï 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.ï 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.ï BREAKER 1(2) EXT ALARM: Selects an operand, usually an external contact input, connected to a breaker alarmreporting contact.ï BREAKER 1(2) ALARM DELAY: Sets the delay interval during which a disagreement of status among the three poleposition tracking operands will not declare a pole disagreement, to allow for non-simultaneous operation of the poles.ï MANUAL CLOSE RECAL1 TIME: Sets the interval required to maintain setting changes in effect after an operator hasinitiated a manual close command to operate a circuit breaker.ï BREAKER 1(2) OUT OF SV: Selects an operand indicating that Breaker 1(2) is out-of-service.ï XCBR ST.LOC OPERAND: Selects a FlexLogicô operand to provide a value for the IEC 61850 XCBR1(2) St.Locdata item.
