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. The
input 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 the
entire disturbance report when being used as triggers.
12.4.6.10 Binary signals
Up to 96 binary signals can be selected to be handled by disturbance report. The
signals can be selected from internal logical and binary input signals. A binary signal
is selected to be recorded when:
• the corresponding function block is included in the configuration
• the signal is connected to the input of the function block
Each 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 disturbance
recording. But they affect the whole disturbance report when they are used as triggers.
The indications are also selected from these 96 signals with local HMI
IndicationMask=Show/Hide .
12.4.6.11 Trigger signals
The trigger conditions affect the entire disturbance report, except the event list, which
runs continuously. As soon as at least one trigger condition is fulfilled, a complete
disturbance 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 importance
of choosing the right signals as trigger conditions.
A trigger can be of type:
• Manual trigger
• Binary-signal trigger
• Analog-signal trigger (over/under function)
Manual trigger
A disturbance report can be manually triggered from the local HMI, PCM600 or via
station bus (IEC 61850). When the trigger is activated, the manual trigger signal is
generated. This feature is especially useful for testing.
