Section 6 – SR-2 Service Procedure A46A
Obtaining Flash Load Files and Preparing Them for Use
A file containing the new software is required in order to perform a flash load. These files are supplied in the
following format:
Microcode Update B0xx for SR2 Microprocessor.exe (where xx = the software revision)
IMPORTANT: There are also flash load files for the SR2 HMI Control Panel. Be sure to select the file for SR2
Microprocessor.
Software flash load files can be obtained in a number of different ways.
• The Thermo King web site www.thermoking.com/.
• An attachment to a Lotus Notes message.
• An attachment to an e-mail message.
Create a sub-directory and detach or download the necessary file or files. The files must then be prepared for
use.
Preparing flash load files for use by Wintrac
Flash load files must be prepared for use before the Wintrac flash load process can be started. To prepare the
files proceed as follows:
1. Using Windows Explorer locate the sub-directory containing the files. The files will be in the format
“Microcode Update B0xx for SR2 Microprocessor.exe” (where xx = the software revision)
2. Double click the desired file. The file will be uncompressed and installed in the sub-directory
Wintrac\Flashload\SR2. If this directory does not exist it will be created automatically. There will be two files
in this sub-directory. However, only one file will appear when the directory is displayed by Wintrac.
The software files are now ready for flash loading using Wintrac.
