2)
The memory size for trend 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 rest storage capacity fall below 31 %, it will mark as red color on User Interface, then the activation
is not possible.

This message is only output if the stored data and the data to be expected exceed the storage capacity of the
SD card.
