5.6 Using SD memory card

The cylinder unit is equipped with an SD memory card interface in FTC.
Using an SD memory card can simplify main controller settings and can store
operating logs. *1
Note: Before inserting or ejecting an SD memory card, confirm that the power supply
earth cable is securely connected and prevent the FTC from being applied with
static electricity (e.g. touch a case body etc.). Otherwise, it may cause a failure of
the FTC due to the static electricity.
<Handling precautions>
(1) Use an SD memory card that complies with the SD standards. Check that the
SD memory card has a logo on it as those shown on lower right figure.
(2) SD memory cards to the SD standards include SD, SDHC, miniSD, micro SD,
and microSDHC memory cards. The capacities are available up to 32 GB.
Choose that with a maximum allowable temperature of 55ºC.
(3) When the SD memory card is a miniSD, miniSDHC, microSD, or micro SDHC
memory card, use an SD memory card converter adapter.
(5) Before inserting or ejecting an SD memory card, make sure to power OFF the
system. If an SD memory card is inserted or ejected with the system powered
ON, the stored data could be corrupted or the SD memory card be damaged.
*An SD memory card is live for a short duration after the system is powered
off. Before insertion or ejection wait until the LED lamps on the FTC control
board are all off.
(6) The read and write operations have been verified using the following SD
memory cards, however, these operations are not always guaranteed as the
specifications of these SD memory cards could change.

Before using a new SD memory card (including the card that comes with the
unit), always check that the SD memory card can be safely read and written to
by the FTC controller.
<How to check read and write operations>
a) Check for correct wiring of power supply to the system. For more details,
refer to section 4.5.
(Do NOT power on the system at this point.)
b) Insert an SD memory card.
c) Power on the system.
d) The LED4 lamp lights up if the read and write operations are successfully
completed. If the LED4 lamp continues blinking or does not light up, the
SD memory card cannot be read or written to by the FTC controller.
(7) Make sure to follow the instruction and the requirement of the SD memory
card's manufacturer.
(8) Format the SD memory card if determined unreadable in step (6). This could
make it readable.
Download an SD card formatter from the following site.
SD Association homepage: https://www.sdcard.org/home/
(9) FTC supports FAT file system but not NTFS file system.
(10) Mitsubishi Electric is not liable for any damages, in whole or in part, including
failure of writing to an SD memory card, and corruption and loss of the saved
data, or the like. Back up saved data as necessary.
(11) Do not touch any electronic parts on the FTC control board when inserting or
ejecting an SD memory card, or else the control board could fail.
