4.2.5
Pause
at
change
of
direction
The
pause
at
change
of
direction
is
for
the
protection
of
the
shutter
motor,
if
the
shutter
actuator
receives
simultaneously
commands
for
the
up
‐
and
down
‐
movement.
A
direct
shift
from
the
one
to
the
other
direction
can
contract
the
duration
of
the
motor
significantly
and
even
by
some
motors
a
total
damage
is
caused.
If
the
shutter
actuator
receives
during
a
running
movement
a
command
for
a
movement
to
the
other
direction,
the
shutter
actuator
will
switch
off
the
movement.
Before
the
shutter
actuator
switches
the
movement
to
the
other
direction
on,
the
actuator
stops
for
the
adjusted
time
for
the
pause
at
change
of
direction.
The
pause
at
change
of
direction
counts
as
well
for
the
change
of
direction
of
the
up
‐
/down
‐
movement
as
for
the
blind
adjustment.
Too
short
adjusted
pause
at
change
of
direction
can
cause
damages
of
the
motor!
Notice
the
manufacturer´s
data
at
the
datasheet
of
the
drive
absolutely.
4.2.6
Switch
‐
on/Switch
‐
off
delay
motor
Some
motors
can
not
bring
the
full
power
at
the
moment
of
switching
it
on,
but
first
after
some
milliseconds.
The
time,
which
the
motor
needs
to
get
the
full
power,
can
be
balanced
with
the
adjustment
of
the
switch
‐
on
delay
of
the
motor.
On
the
other
hand
there
are
motors,
which
run
after
it
was
switched
off.
This
characteristic
can
be
balanced
by
using
the
setting
switch
‐
off
delay
motor.
4.2.7
Position
of
blinds
at
end
of
driving
only
at
blinds
By
using
the
adjustment
“position
of
blinds
at
end
of
driving“
can
be
adjusted
in
which
position
the
blinds
shall
be
set
after
a
down
‐
or
an
up
‐
movement.
The
shutter
actuator
drives
automatically
to
this
position
after
the
end
of
a
blind
‐
movement.
The
position
of
blinds
at
end
of
driving
can
be
set
percentage
in
1%
steps,
from
0%
to
100%,
whereby
0%
full
opened
and
100%
full
closed
correspond.
4.2.8
Short
time
operation
only
at
blinds
from
hardware
version
2.2
The
short
time
operation
helps
you
to
drive
the
blinds
to
a
certain
position,
e.g.
for
sun
protection.
With
small
steps,
the
blinds
can
be
driven
to
every
possible
position.
It
is
often
useful
to
set
the
short
time
operation
as
a
multiple
of
the
movement
time.
So
the
blinds
can
be
driven
from
the
bottom
to
the
top,
or
the
other
way
around,
in
a
certain
number
of
steps.
