Up to 10 analog signals (five voltages and five currents from the transformer module)
can be selected for recording and triggering if the disturbance recorder function is in-
stalled. If fewer than 10 signals are selected, the maximum storing capacity in the flash
memories, regarding total recording time are increased.
A user-defined name for each of the signals can be programmed in the terminal.
For each of the 10 analog signals,
2SHUDWLRQ 2Q
means that it is recorded by the dis-
turbance recorder. The trigger is independent of the setting of
2SHUDWLRQ
, and triggers
even if operation is set to
2II
. Both undervoltage and overvoltage can be used as trigger
condition. The same applies for the current signals.
1 Pre-fault or pre-trigger recording time. The time before the fault including
the operate time of the trigger. Use the setting tPre to set this time.
2 Fault time of the recording. The fault time cannot be set. It continues as
long as any valid trigger condition, binary or analog, persists (unless limited
by tLim the limit time).
3 Post fault recording time. The time the disturbance recording continues
after all activated triggers are reset. Use the setting tPost to set this time.
tLim Limit time. The maximum allowed recording time after the disturbance
recording was triggered. The limit time is used to eliminate the conse-
quences of a trigger that does not reset within a reasonable time interval. It
limits the maximum recording time of a recording and prevents subsequent
overwriting of already stored disturbances.Use the setting tLim to set this
time.
