Install the microSD Card
The Micro820 controller has a card slot for a microSD card. The microSD card is primarily used
for project backup and restore. It is also used for data-logging and recipe and to change controller
mode under specific conditions.
1. Insert the microSD card into the card slot.
You can install the microSD card in one orientation only. The beveled corner should be
at the bottom. If you feel resistance when inserting the microSD card, pull it out and
change the orientation.
WARNING: When you insert or remove the microSD card while
power is on, an electrical arc can occur. This could cause an
explosion in hazardous location installations.
Be sure that power is removed or the area is nonhazardous before
proceeding.

an embedded microSD card slot. It supports Class 6 and 10 SDSC and
SDHC microSD cards, with FAT32/16 formats, 32 GB maximum size.

recommended. The microSD card file system supports only one
file partition.
