If Operation = Disabled, no waveform (samples) will be recorded and reported in graph.However, Trip value, pre-fault and fault value will be recorded and reported. The inputchannel can still be used to trig the disturbance recorder.If Operation = Enabled, waveform (samples) will also be recorded and reported in graph.The analog signals are presented only in the disturbance recording, but they affect theentire disturbance report when being used as triggers.12.4.6.10 Binary signalsUp to 96 binary signals can be selected to be handled by disturbance report. The signalscan be selected from internal logical and binary input signals. A binary signal is selectedto be recorded when:• the corresponding function block is included in the configuration• the signal is connected to the input of the function blockEach of the 96 signals can be selected as a trigger of the disturbance report (Operation =Operation—>TrigDR =Disabled). A binary signal can be selected to activate the yellow(PICKUP) and red (TRIP) LED on the local HMI (SetLED = Disabled/Pickup/Trip/Pickup and Trip).The selected signals are presented in the event recorder, sequential of events and thedisturbance recording. But they affect the whole disturbance report when they are used astriggers. The indications are also selected from these 96 signals with local HMIIndicationMask=Show/Hide.12.4.6.11 Trigger signalsThe trigger conditions affect the entire disturbance report, except the sequential of events,which runs continuously. As soon as at least one trigger condition is fulfilled, a completedisturbance report is recorded. On the other hand, if no trigger condition is fulfilled, thereis no disturbance report, no indications, and so on. This implies the importance ofchoosing the right signals as trigger conditions.A trigger can be of type:• Manual trigger• Binary-signal trigger• Analog-signal trigger (over/under function)Section 12 1MRK 511 287-UUS AMonitoring486Technical manual
