Basic functions
82
If Operation Ch = "On", waveform (samples) is 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.
Binary signals
Up to 64 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 in two occasions.
• Corresponding function block is included in the configuration
• Signal is connected to the input of the function block
Each of the 64 signals can be selected as a trigger of the disturbance report (Operation
Ch = "Off"). A binary signal can be selected to activate the yellow (START) and red
(TRIP) LED on the LHMI: Set LED = "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 64 signals with LHMI: Show
indication="Show/Hide".
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. It is important to choose the
right signals as trigger conditions.
There are three different trigger types.
• Manual trigger
• Binary-signal trigger
• Analog-signal trigger (over/under function)
Manual trigger
A disturbance report can be manually triggered from the LHMI, WHMI, 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.
Binary signal trigger
Any binary signal state, that is, logic one or a logic zero, can be selected to generate
a trigger ( Trigger level = "Trig on 0/Trig on 1"). When a binary signal is selected to
generate a trigger from a logic zero, the selected signal is not listed in the indications
list of the disturbance report.
