4–366 869 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUALCONTROL CHAPTER 4: SETPOINTSTrip BusThe 869 relay provides six identical Trip Bus elements. The Trip Bus element allowsaggregating outputs of protection, control elements, inputs without using FlexLogic andassigning them in a simple and effective manner. Each Trip Bus can be assigned to trip,alarm or the other logic actions. Simple trip conditioning such as latch, delay, and seal-indelay are available.Path: Setpoints > Control > Trip Bus 1FUNCTIONRange: Disabled, Trip, Alarm, Latched Alarm, ConfigurableDefault: DisabledINPUT 1 to 16Range: Off, Any FlexLogic operandDefault: OffThese settings select a FlexLogic operand to be assigned as an input to the Trip Bus.LATCHINGRange: Enabled, DisabledDefault: DisabledThe setting enables or disables latching of the Trip Bus output. This is typically usedwhen lockout is required or user acknowledgement of the relay response is required.RESETRange: Off, Any FlexLogic operandDefault: OffThe trip bus output is reset when the operand assigned to this setting is asserted.PICKUP DELAYRange: 0.000 to 6000.000 s in steps of 0.001 sDefault: 0.000 sDROPOUT DELAYRange: 0.000 to 6000.000 s in steps of 0.001 sDefault: 0.000 sBLOCKRange: Off, Any FlexLogic operandDefault: OffOUTPUT RELAY XFor details see Common Setpoints.EVENTSRange: Enabled, DisabledDefault: EnabledTARGETSRange: Self-reset, Latched, DisabledDefault: Self-resetNOTENOTE:The Any Trip operand must not be programmed as an input for the Trip Bus function.
