SD Memory Module Removal / Replacement
The ATX10 Memory Module is a dual plug daughter
board located on the back side of the ATX10 transmitter
module. See Figure 4 for location. The SD memory
card is attached to the memory module by a locking
connector.
The memory module is designed to be easily removed
from the transmitter module. To remove the memory
module, simply grasp it with your fingers and pull it
from the transmitter module circuit board (no tools
required). The memory module is keyed to ensure
correct orientation when replaced.
To remove the SD card from the memory module, follow
the procedure shown in Figure 5.
Note
the SD card and memory module are not intended
to be hot-swappable. Proper precautions must
be observed when removing or replacing the
memory module/SD card.
Prior to removal of the Memory Module/SD card, it is
recommended that the REMOVE option be selected
via HART. This will disable communication to the SD
card and annunciate an advisory fault. This is similar
to selecting the option to “Safely Remove” a flash drive
on a PC.
After re-inserting the Memory Module/SD card, the
ENABLE option should be selected via HART. This
should re-establish communication with the card after
a memory module initialization.
The ATX10 Transmitter is intended to be used with the
SD card in place, but will continue to perform its safety
function should the memory be removed, damaged, or
corrupted. An advisory fault (flashing yellow LED) will
indicate conditions where the SD card is missing, non-
operational, or of incorrect specification.
Note
the detector will continue to operate with an SD
advisory fault present, however, the fault must be
corrected in order to clear.
In the event that the SD card will not be used, it is possible
to disable it entirely including fault annunciation. This is
done with the DISABLE option selected via HART. This
operation is permanent and the SD card will remain
disabled, with no fault annunciation, even if power is
cycled to the ATX10. The SD card can be re-enabled
with the ENABLE option selected via HART.
Note
It is Not recommended to select the DISABLe
option unless absolutely necessary as the
benefits of real-time data logging will lost.
