automatic section power recognition process in
progress process can have 3 or 6 steps
C=0 C=0 C=0 C=0
no capacitors have been successfully detected in
automatic section power recognition process or
in manual section value specification mode
(parameter 20), parameters 21 through 26 have not
been set properly or
all capacitive sections have been automatically
disabled because of error (parameter 25) or they are
set as fixed (parameter 26)
if automatic section power
recognition process is set, it will
be automatically repeated in
about 15 minutes or you can
specify values of parameters 21
through 26 manually
