The SD card may never be installed in/or removed
from the CCR 2 when data is being written to it.
Disrespecting this rule may lead to:
– data loss
– SD card damage
– CCR 2 control damage.
INSTALLING THE SD CARD
Disconnect the control from the power supply
for at least five seconds before inserting the SD
card. The SD card may only be installed after this
pause.
REMOVING THE SD CARD
From ACCESS CODE menu quadruple press up
arrow key "▲" without entering any code it will
give access to "SD Card Exchange". SD card can
be pulled out safely from CCR2 (process of date
recording is interrupted).
Power failures occuring when data is written to
the SD card may also corrupt the archive or even
damage files stored on the card. To reduce the
risk, it is recommended to use a buffered power
supply for a CCR 2 used with the data archiving
function and to set the "Archive" setting to "2
Files." The archived files will be doubled, but the
storage space is halved.
