The unit records data to a USB-Flash memory or micro-SD flash memory card.
The unit will record data in a directory with the first 11 characters of its site-id parameter. In order to avoid
confusion between records, it is highly recommended to configure the site-id parameter according to the
compressor installation site. Thus, the same memory module may be used for recording data from
different controllers. Inside the directory, the unit will make a separate directory for each year of
recording. The directory will simply be named by year (2018, 2019, etc.) Inside the directory, the
controller will records data in a different file for each day of recording. The record will be named
YYYMMDD (ex.
“20190331”, meaning March 31, 2019). Thus, alphabetical listing will produce a sorted
list by date of recording. The recorded file type is CSV (comma separated values). This is a text file which
can be opened using Microsoft Excel without any loss of information. It can also be opened with any text
editor such as Notepad. Inside the file, each record consists of a line listing a large set of measured
parameters. The recorded parameters list is not adjustable. The controller records all practically
necessary parameters.
The
“
.csv
” file is basically a text file format. This allows for it to be opened by any text editor in any
operating system.
When opened with Microsoft Excel, the values will appear in tabulated form, enabling application of
formulas, graphs and other features of Excel.
