Notes on SD Card Handling
1. The SD card access LED flashes red when the SD card is being accessed. Do not remove the SD
card while the LED is flashing. Doing so may destroy data on the SD card.
2. When removing the SD card, check that the SD card access LED has turned off, then select
[Storage Removal] in the system menu, or press the [Storage Removal] switch.
3. Do not turn off power to the unit when the SD card is being accessed.
4. Make a backup copy of the SD card at regular intervals.
5. If a disk error occurs and data read/write operations are disabled, execute ScanDisk on Windows
and try to restore the disk.
If the disk cannot be restored, format the device. Note that formatting will completely erase all
stored data. (For information on executing ScanDisk on Windows, refer to the relevant Windows
manual.)
6. SD cards have a limited number of write cycles. Consequently, frequent writing at short intervals
may shorten the service life of SD cards. When using an SD card to save logging/alarm data, take
the logging time/monitoring intervals into consideration. Also, avoid repeated writing using the
CYCLE macro command.
