Analyzer Installation & Connections
16
3.4.5 Analog Output Connections – A-OUT
There are two active 4…20 mA output signals
*
for load up to 600 ohm. The configura-
tion is as follow:
Terminals 1 & 2
= Analog Output 1 for the remote indication of oxygen level
Terminal 3 = No connection
Terminals 4 & 5 = Analog Output 2 (optional)
* Active output signal means signal voltage from the G36p analyzer.
For setting of analog outputs please see section 5.4.
3.4.6 SD Card
The SD card is used for storage of the historical trend of O
2
and the logbook. The SD
card can also be used to load a new software version to the analyzer.
Data log
The internal memory of the analyzer measures and saves six values every minute. How-
ever, the internal memory can only store one hour of logging, which is equal to 360 log
values. If there is no SD card installed the new log values will supersede the old log val-
ues. This means there will be no historical trend curve and alarm logs as well.
However, if you place an SD card in the analyzer, the internal memory will be saved on
the SD card every minute. If the analyzer alarm and logbook functions are ON, the
alarms will also be logged on the SD card.
There are two log files in the SD card, a log file for O
2
values
g1x.log
and a log file for
alarms g1x.alm .
Attention
In order to read the log files directly from the SD card using a Windows-operated
computer, the user has to use Notepad.
Do not open the log files in WordPad. WordPad will damage the format of the log
files, and the analyzer will be unable to log any more data on the SD card.
The best way to read the log files is to copy them to the local disk of your computer and
then open them from your computer. This way, you can use any program that can open a
txt-file including Notepad, WordPad, MS Word and MS Excel
The data in the log file – g1x.log includes 5 columns, i.e.:
