II.2.2. CAUCHO DE POLICLOROPRENO
All active system parameters can be logged using ESP for a user-determined period of time. The file that is saved is a binary file (file extension .AClog) that must be converted or extracted into a usable file for-mat. Using the Log file Processor program installed with ESP, the binary file can be converted into a Tab Separated Value File (.TSV) readable with Microsoft® Excel or the file can be converted into a text file (.TXT).
Once the data is readable as a .TSV or .TXT file, the user can review, chart, and/or trend the data logged as desired. Complete the following:
1. In ESP, click on the “Start Logging All” button located on the button bar. A file will automatically be created on the PC’s hard drive with the engine data being logged.
NOTE: The “Start Logging All” and the “Stop Logging All” buttons cannot be active at the same time. When one is active, the other becomes inactive.
Figure 3.10-16. Start Logging All Button
NOTE: Allow the engine to run while the data is being logged. It is recommended that 1– 2 hours be the maximum amount of time that is allowed to log data to avoid creating a file too large to open with applications that have a minimum number of columns/rows, such as Microsoft® Excel.
2. When you want to stop logging data, click the
“Stop Logging All” button.

Log File Processor.4. Determine whether you would like to convert the file into a .TXT file that can be opened in Microsoft® Word or another word processing program, or if you would like to extract the file into a .TSV file that can be opened and charted in Microsoft® Excel or another spreadsheet program.
• If you want to create a .TXT file, continue with “Cre-ate Text File.”
• If you want to create a .TSV file, continue with
“Create .TSV File.”
CREATE TEXT FILE
The following steps explain how to extract a logged file (a file with the extension .AClog) into a .TXT file that can be opened in Microsoft® Word or another word processing program.
1. Start the Log File Processor program and click the
“Create Text File” button.
Figure 3.10-18. Log File Processor
2. Select the folder that contains the log file to con-vert and click the “Open” button.
NOTE: All log files are saved to a directory. Typically, this directory is located at C:\Program File\Esm\Logs.
Within the directory “Logs” there is a subdirectory (or subdirectories) named with the engine serial number.
The log file is saved in the subdirectory of the appropriate engine.

5. Close the Log File Format Extractor dialog box by clicking “X” in the upper right corner. The Log File Pro-cessor program is now closed.
6. Using Microsoft® Excel or another spreadsheet software program, open the .TSV file that was just cre-ated. The .TSV file will be in the same subdirectory as the .AClog file. Select desired .TSV to be opened and click “Open.”
NOTE: If the spreadsheet program being used does not show the .TSV file, try changing the “Files of type:”
to read “All Files.”
7. Using Microsoft® Excel, you can then plot or chart the logged parameters. Refer to Microsoft® Excel soft-ware documentation for instruction on creating charts and graphs.
