Therefore, this feature can beblocked until the machine is online and adequate time has expired during which the fieldhad been applied. From that point forward, the reactive power trip and alarm elementswill be active. A value of zero for the block time indicates that the reactive powerprotection is active as soon as the generator comes online.BLOCKRange: Off, Any FlexLogic operandDefault: OffEVENTSRange: Disabled, EnabledDefault: DisabledTARGETSRange: Disabled, Self-reset, LatchedDefault: Self-reset
