4. TROUBLESHOOTING

4.1 PROGRAM DOWNLOAD

4.1.1 OVERVIEW
Here are some important points to keep in mind when downloading software:
If an error interrupts download processing, the machine cannot operate normally
with the program software only partially downloaded.
When download processing execution starts, "Downloading..." is displayed and
when downloading has completed successfully, the message is cleared.
If the download is interrupted when the "Downloading ..." message is displayed,
the machine does not attempt a re-try.
The program that downloads firmware from an SD card is part of the GW
controller software. If downloading this software is interrupted, the program
stored in the machine may be corrupted. Because of this, it may not be possible
to restart the downloading program. (In addition, if the GW controller software
cannot be downloaded, other software on other SD cards cannot be
downloaded.) However, it may be possible to restart the program without
replacing the board by setting DIP SW 1 on the controller to ON, and re-starting.
4.1.2 RECOVERY METHODS
When an error occurs during downloading, an error code is displayed on the
operation panel.
If the download procedure can be re-started, re-start the download procedure.
If the download procedure cannot be downloaded for other than the GW
controller, replace the board where the downloaded program is stored.
If the download procedure cannot be downloaded for the GW controller, set DIP
SW 1 to ON. Power the machine OFF and ON to start the downloading program.
After downloading has completed, set the DIP SW to OFF then power the
machine OFF and ON again.
