Appendix F – Removable Media
To ensure that historical and performance information is stored properly be sure to insert a
Micro - Secure Digital (SD) card in the proper slot at all times. See section 6.6 for installation
instructions.
The SD card stores all information in standard comma separated values (*.CSV) format for
easy access with any computer. Remove the SD card from the CL1 as described in section 6.6
and transfer the files to your personal computer*. The files are best viewed with programs
that convert CSV format to rows and columns (Microsoft Excel, OpenOffice, etc) but can be
viewed with any text editor.
Figure F.1 shows the folders found on the SD card depending on the configuration or your
CL1 and the use of the SD cards. All files have the format YYMMDD.CSV. A new file is
automatically created each day – be sure that the Date/Time are set correctly (Section 5.5.e)

F.1 Concentration Log Files (YYMMDD*.CSV)
Whenever the concentration detected exceeds the preset alarm level in the CL1, the system
starts a log file on the SD card (if available). The log file will update approximately every 2
seconds until the gas is no longer detected. A sample alarm file is shown in figure F.2 The
columns show: Date, Time, Gas Concentration, Alarm Level 1, Alarm Level 2, and the
selected gas range.

Each time a new event, fault or alarm is added to the History log on the CL1, the message is
written to the current days event log file on the Micro SD card (if available). A sample event
log is shown in figure F.3. The columns show: Date, Time, Event Number, and Action
(unused). The Event Numbers are listed in Appendix D.
