Service and repair
The following options are available.
•
”Change after Load”:
The system will initiate reprogramming of the timer's internal flash
memory (if necessary, after all backup processes have been ac­
tivated, refer to "Save Counter", "Backup" options). During this
process, the timer will copy the contents of a dedicated RAM
memory range to which data was stored using the "FW Load"
command button into the flash memory.
If "Change after Load" is not activated, the copying process must
be manually started later on in the course of the firmware update
by pressing the "FW Change" command button.
Do not use "Change after Load" unless none of the weld timers
involved actively participates in the production process for the du­
ration of the complete firmware update!
• ”Quit after done”:
The program will be automatically closed after the firmware up­
date (and the completion of Restore, if activated; refer to "Save
Counter", "Backup" functions) of all selected timers.
• ”Save Counter”:
All actual counter statuses (electrode count and cutter wear, if
programmed) will be saved on the programming terminal prior to
programming the flash memory and will be restored to the timer
after Timer Reset.
• "Backup":
All welding parameters or UI controller parameters will be saved
in the programming terminal prior to programming the flash
memory and will be restored to the timer after Timer Reset.
5.
Check whether communication with the timers selected for the firm­
ware update is still possible.
Click on the "List" command button.
Communication works properly if all currently active firmware ver­
sions are displayed in the new "SW Version" window after a few se­
conds.
Then close the "SW Version" window.
Communication is interrupted if the firmware version is not dis­
played, but rather the text: "--N/A---".
In this case, you should check whether the timer in question has
been properly connected, switched on, and completely booted. A fi­
rewall activated on the programming terminal may also inhibit com­
munication.
Then close the "SW Version" window and check the communication
again.
6.
Click on the "FW Load" command button.
The currently selected firmware file (refer to step 2.) is loaded by the
programming terminal to a dedicated RAM memory range of the
timer. The progress is indicated by a status bar in the "SST" (German
abbreviation of 'weld timer') field.
When loading has been completed, the system will display the new
firmware version loaded in the "SST" field.
If the firmware is generally suitable for the timer, the background of
the "SST" field will be green, otherwise it will be red.
