TRANSIENT RECORDER
520
Low Triggering
Range: Enabled, Disabled
Default: Disabled
This setting selects the low triggering function for the analog channel. When set to
"Trigger Only" or "Trigger/Re-Trigger," the transient recorder initiates data capture when
the magnitude of the signal is less than the value of the
record contains both pre-fault and fault data. The channel must return to the off state
before it can generate a subsequent trigger.
When set to "Trigger/Re-Trigger" or "Trigger Only," the transient recorder is re-triggered
when the magnitude of the signal is less than the value of the
resulting transient record contains fault data only. A re-trigger is generated again at the
end of the record if the magnitude is less than the
triggers is less than the
Maximum Re-Trigger
Note that only phasor magnitudes, RMS magnitudes, frequency, and power can be used
as analog triggers.
Low Pickup
Range: 0.0 to 1000000.0 in steps of 0.1
Default: 1000.0
This setting specifies the magnitude of the signal required to produce a trigger or re-
trigger. This setting is expressed in primary values. The units depend on the value of the
setting.
Available Signal
Block Trigger
Range: any FlexLogic operand or shared logic operand
Default: OFF
When the operand assigned to this setting is asserted, all high and low triggers to the
specified analog channel are inhibited.
