Setting information
Parameter: Disk Activity Symbol
•
Default Setting: Disabled
New Events, Waveform Records or Fault Records are held in volatile RAM. To increase the data
storage capacity data is archived to non-volatile memory. Archiving is a secondary task so data transfer is
initiated during quiescent operating periods of the device.
Archiving may take several minutes, if power to the device is lost during this time some data will also be
lost.
The relay can provide a visual indication at the top-right position of the LCD that data storage is taking
place. A disc symbol is displayed showing that the copying of Events, Waveform Records or Fault
Records, to non volatile disk storage is taking place. This symbol is displayed when this setting is
enabled. Binary outputs can also be energized during periods of device or waveform archiving.
The inverted A symbol at the top-right position of the LCD indicates that new Events, Waveform
Records or Fault Records are currently being held in volatile RAM and have not yet been archived.
