Event recorder (ER)
2.1
Application
Use the event recorder to obtain a list of binary signal events that occurred during the distur-
bance.
2.2
Design
When a trigger condition for the disturbance report is activated, the event recorder collects time
tagged events from the 48 binary signals that are connected to disturbance report and lists the
changes in status in chronological order. Each list can contain up to 150 time tagged events that
can come from both internal logic signals and binary input channels and up to ten disturbances
can be recorded. Events are recorded during the total recording time which depends on the set
recording times and the actual fault time.
Events can be viewed via SMS and SCS.
