corresponding information is available on the non-calculated output (AI4) on theSMAI function block. Connect the signals to the AxRADR accordingly.For each of the analog signals, Operation = On means that it is recorded by thedisturbance recorder. The trigger is independent of the setting of Operation, andtriggers even if operation is set to Off. Both undervoltage and overvoltage can be usedas trigger conditions. The same applies for the current signals.If Operation = Off, no waveform (samples) will be recorded and reported in graph.However, Trip value, pre-fault and fault value will be recorded and reported. Theinput channel can still be used to trig the disturbance recorder.If Operation = On, 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. Thesignals can be selected from internal logical and binary input signals. A binary signalis selected to 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= Off). A binary signal can be selected to activate the yellow (START) and red (TRIP)LED on the local HMI (SetLED = Off/Start/Trip/Start and Trip).The selected signals are presented in the event recorder, event list and the disturbancerecording. But they affect the whole disturbance report when they are used as triggers.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 event list, whichruns 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,there is no disturbance report, no indications, and so on. This implies the importanceof choosing the right signals as trigger conditions.A trigger can be of type:• Manual trigger• Binary-signal trigger• Analog-signal trigger (over/under function)1MRK 511 287-UEN A Section 12Monitoring453Technical manual
