PART IX - SD CARD FILE FORMAT
.
The controller is equipped with an SD (Secure Digital) memory card on the motherboard to store the Pressure log, Event log,
Operators Manual in PDF format, Auxiliary Alarm configuration information and the controller drawings in PDF format.
The SD card is located on the right hand edge of the motherboard and is removed by pressing in on the right edge of the card to
release from the card holder. When the SD card is removed, data is still being recorded on temporary flash memory on the
motherboard. Once the card is replaced, the stored data will be written back to the SD Card. When the SD card is removed, the
LCD display will indicate that the card is missing and that is should be replaced. If the card is not replaced within approximately
1 minute, the alarm will sound and the System Fault LED will come on. Once the SD card is replaced, the System Fault LED will
go out but the Alarm Silence button must be pressed to silence the alarm horn. The data stored on the SD card is in standard
ASCII text format and can be read by an computer equipped with an appropriate SD card reader. These are readily available at
any electronics store. The data on the SD card is in the following format:
PressXXX.txt file
Data is stored in a standard comma delimited file as follows:
07/27/07, 11:07:52, 060
Date Time Pressure
Each file starting with “Press” contains one days worth of pressure data.
