14 CHANGE OF PROGRAM
14.1 General
When changing programs, the flash memory (IC15)
must be replaced. In doing this, the trimming data set
will be replaced by the preset values of the new flash
memory, see page 35.
To keep the set trimming data, the data must first be
stored in the welding power source and then be sent
back to the PEH electronics when the new flash
memory is installed.
Store trimming data for future upgradings of the
program if the complete PEH electronics are to be
replaced.
N.B. When changing the flash memory (IC15) make
sure that the program versions are compatible between
for example the PEH and the welding power source.
