Disturbance report - Settings
This MMI submenu is only available when the Disturbance Recorder
option is installed.
For each of the 10 analogue signals (five voltages and five currents),
Operation = On means that it is recorded by the Disturbance Recorder. If
fewer than 10 signals are selected, the maximum storing capacity in the
flash memories for total recording time becomes longer.
Both undervoltage and overvoltage can be used as triggering condition.
The same applies for the current signals. The triggering is independent of
the setting of Operation and triggers even if Operation = Off.
A user-defined name for each of the signals can be entered. It can consist
of up to 13 characters. It is found at:
Configuration
AnalogInputs
See "Fault locator", in document "1MRK 580 138-XEN", for more infor-
mation.
MMI submenu:
ServiceReport
DisturbReport
SequenceNo
Normally, this setting option is never used. Each disturbance is assigned a
number in the Disturbance Report. The first disturbance each day nor-
mally receives SequenceNo = 0. The value of SequenceNo that can be
read in the Service Report is the number that will be assigned to the next
disturbance registered during that day.
In normal use, the sequence number is increased by one for each new dis-
turbance until it is reset to zero each midnight.
