8.3.6.5 Memory Management
Default Settings and Setting Ranges
1)
The memory sizes for event list, PQ records, fault records, and mains signalling voltage records can be
changed.
2)
The memory size for continuous recording is calculated automatically and forms the difference to 100 %
of the total memory size. The maximum total memory size of 100 % cannot be exceeded due to
parameterization errors.
3)
If the residual memory capacity falls below 31 %, activation is no longer possible. In this case, the
Action
was not successful
indication appears on the status bar
.

nalling voltage) 14 % to 20 %

NOTE
If the device has been recording data for a longer period, a modification of the memory areas can lead to the
following indication:
„
Memory size should not be changed now. If you active changes, all PQ data will be lost. Please backup data
before activation or cancel changes.
”
This indication is issued only if the stored data and the expected data would exceed the memory capacity of
the SD card.
