Fault Recorder
7.2 Function-Group Type Recorder
NOTE
i

In the mode off , the continuous recorder no longer records any measured values, but continues to record
device statuses (time jumps, modes on/off, as well as disconnection and recovery of the supply voltage).
PQDif recordings are still generated, even though the continuous recorder is set to the mode off. It is
recommended to delete the recorder instance in case of long-term non-use.
Averaging of the Continuous Recorder
If the Averaging time parameter is configured to 600 s or 900 s , the data are made available cycli-
cally after 2 hours. This setting defines the time frame in a 2-hour cycle. That means, the activation occurs at
00:00, 02:00, 04:00 UTC, etc. If the averaging time is less than 600 s, the cycle time is 10 minutes.
Ring-Buffer Mode
With the continuous recorder, data are stored on the flash memory in blocks. With an averaging time up to
and including 300 seconds, these blocks cover a time span of 10 minutes. With longer averaging times, the
blocks cover a time span of 2 hours. If while recording a record, the device determines that the free space
remaining on the record partition is too small, the oldest data block is deleted automatically. During this
process, complete time segments in the specified grid are always lost.
Disconnection and Recovery of Supply Voltage
NOTE
i
i
If the supply voltage of the device is disconnected intentionally or by mistake, measuring gaps will appear
for the period of the disconnection. However, the recorded data remains stored and can be read after
recovery of the supply voltage.
