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 remote controller settings and can store operating logs. *1
*1 To edit main remote controller settings or to check operating data, an Ecodan service tool (for use with PC) is required.
<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 of those shown to the right.
(2) SD memory cards to the SD standards include SD, SDHC, mini SD, micro SD,
and micro SDHC 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 mini SD, mini SDHC, micro SD, or micro SDHC
memory card, use an SD memory card converter adapter.
(4) Before writing to the SD memory card, release the write-protect switch.
(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 mem-
ory cards, however, these operations are not always guaranteed as the specifi-
cations 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 if the read and write operations are successfully
completed. If the LED4 lamp continues blinking or does not light, the SD
memory card cannot be read or written to by the FTC controller.
