=> insert the microSD card holder correctly
l
Corrupted filesystem on the microSD card
=> Reformat the microSD card
l
Faulty microSD card

CAUTION
DATA LOSS
If the microSD memory card is being written to and a voltage drop
occurs or the card is removed, data may be lost or the microSD
memory card may be ruined.
Insert the microSD card only when the easyE4 is de-energized.
Do not write to microSD cards constantly:
l
microSD cards have a limited number of write cycles.
l
If there is a voltage drop while a write operation is in progress,
data loss is highly likely to occur.
Remove the microSD card only when the easyE4 is de-energized.
