The
setting
“drive
to
former
position”
let
the
shutter
actuator
drive
the
channel
to
the
position,
which
it
had
before
the
alarm
was
activated.
If
you
chose
“no
action”
for
the
action
of
an
activated
channel,
this
setting
will
have
no
effect
to
the
position
of
this
channel.
Furthermore
the
shutter
actuator
can
drive
the
channel
to
the
top
or
the
bottom
at
the
reset
of
an
alarm.
The
setting
“action
at
reset
of
alarms”
is
always
valid
for
the
complete
channel,
even
if
you
have
chosen
three
different
settings
for
the
three
possible
alarms.

Reaction
to
bus
power
faults
For
the
“reaction
when
bus
power
down”
as
well
as
for
the
“reaction
when
bus
power
up”
three
setting
options
are
available.
The
channel
can
drive
to
a
defined
value
as
well
for
the
bus
power
breakdown
as
for
the
bus
power
return
and
drive
to
the
top
or
to
the
bottom.
The
setting
“no
action”
let
the
channel
maintain
in
its
actual
position.
It
is
important
to
note,
that
the
shutter
actuator
can
not
be
addressed
via
the
bus
during
a
bus
power
breakdown
and
so
can
not
be
driven
in
its
„normal
way“.
