Behavior
at
bus
power
up/down
Every
channel
can
occupy
a
certain
state
as
well
in
case
of
a
bus
power
breakdown
as
in
case
of
a
bus
power
return.
The
channel
can
be
switched
off
or
on,
but
also
stay
in
its
current
state
by
choosing
the
parameter
“no
change”.
To
avoid
problems
in
case
of
a
bus
power
breakdown,
you
should
adjust
this
parameter
very
conscientious.
Because
there
is
no
controlling
possible
as
long
as
the
bus
power
is
down.
