For optimum performance, the microSD card should not be more than
90% full. Regularly check available space on your microSD card and
ensure that the card is exclusively used for the Micro800 controller and
no unnecessary files are present. Regularly delete old datalog files and
directories.
Do not remove the microSD card or power down while operations such as
upload, download, delete, search, backup and restore are ongoing to
prevent data loss. A blinking SD status LED indicates that these
operations are ongoing.
The SD status LED will not blink when flash upgrading the firmware from
the microSD card.
To prevent data loss, recipe and datalog function blocks must indicate
Idle status before microSD card is removed.
