Transferring the memory unit to a new regen supply module

When a regen supply module is replaced, the parameter settings can be retained by
transferring the memory unit from the defective regen supply module to the new
module.
WARNING! Do not remove or insert a memory unit when the regen supply module is
powered.
After power-up, the regen supply module will scan the memory unit. If a different
application program or different parameter settings are detected, they are copied to
the regen supply module. This may take a few moments; the LED display will read
"L" while copying is in progress.
