GE Multilin B90 Low Impedance Bus Differential System 5-315 SETTINGS 5.2 PRODUCT SETUP55.2.8 USER-PROGRAMMABLE FAULT REPORTPATH: SETTINGS PRODUCT SETUP USER-PROGRAMMABLE FAULT REPORT USER-PROGRAMMABLE FAULT REPORT 1(2)When enabled, this function monitors the pre-fault trigger. The pre-fault data are stored in the memory for prospective cre-ation of the fault report on the rising edge of the pre-fault trigger. The element waits for the fault trigger as long as the pre-fault trigger is asserted, but not shorter than 1 second. When the fault trigger occurs, the fault data is stored and the com-plete report is created. If the fault trigger does not occur within 1 second after the pre-fault trigger drops out, the elementresets and no record is created.The user programmable record contains the following information: the user-programmed relay name, detailed firmwarerevision (5.7x, for example) and relay model (B90), the date and time of trigger, the name of pre-fault trigger (a specificFlexLogic™ operand), the name of fault trigger (a specific FlexLogic™ operand), the active setting group at pre-fault trig-ger, the active setting group at fault trigger, pre-fault values of all programmed analog channels (one cycle before pre-faulttrigger), and fault values of all programmed analog channels (at the fault trigger).Each fault report is stored as a file to a maximum capacity of ten files. An eleventh trigger overwrites the oldest file. TheEnerVista UR Setup software is required to view all captured data. A FAULT RPT TRIG event is automatically created whenthe report is triggered.The relay includes two user-programmable fault reports to enable capture of two types of trips (for example, trip from ther-mal protection with the report configured to include temperatures, and short-circuit trip with the report configured to includevoltages and currents). Both reports feed the same report file queue.The last record is available as individual data items via communications protocols.• PRE-FAULT 1 TRIGGER: Specifies the FlexLogic™ operand to capture the pre-fault data. The rising edge of thisoperand stores one cycle-old data for subsequent reporting. The element waits for the fault trigger to actually create arecord as long as the operand selected as PRE-FAULT 1 TRIGGER is “On”. If the operand remains “Off” for 1 second, theelement resets and no record is created.• FAULT 1 TRIGGER: Specifies the FlexLogic™ operand to capture the fault data. The rising edge of this operandstores the data as fault data and results in a new report. The trigger (not the pre-fault trigger) controls the date and timeof the report.• FAULT REPORT 1 #1 to FAULT REPORT 1 #32: These settings specify an actual value such as voltage or currentmagnitude, true RMS, phase angle, frequency, temperature, etc., to be stored should the report be created. Up to 32channels can be configured. Two reports are configurable to cope with variety of trip conditions and items of interest.
