Other/
Examples
of
use
At
this
chapter,
examples
of
use/areas
of
use
for
the
presence
detector
are
given.
The
examples
are
only
suggestions
and
if
necessary
they
must
be
adapted
to
the
actual
state.
4.7.1
Blackboard
light
via
second
light
group
For
switching
the
light
in
a
classroom
according
to
its
specific
use,
a
presence
detectore
is
used
for
switching
the
room
light.
But
often
a
second
light
at
the
blackboard
is
necessary
for
which
a
second
light
group
can
be
used.
This
light
must
also
switch
on
request
and
shall
switch
off
automatically,
when
the
teacher/lecturer
leaves
the
area
before
the
blackboard
again.
For
realizing
this
scenario
in
small
rooms,
only
one
presence
detector
is
needed.
At
greater
rooms
a
second
presence
detector,
which
is
used
as
Slave
can
be
useful.
The
first
presence
detector
for
the
blackboard
light
must
be
parameterized
as
follows:
Selection
of
lightgroups:
2
light
groups
1.
light
group:
Operating
mode:
fully
automatic
Active
sensors:
1234
other
parameters:
according
to
usage
2.
light
group:
Operating
mode:
semi
automatic
Active
sensors:
1234
other
parameters:
according
to
usage
The
output
objects
of
the
light
group
must
be
connected
to
the
switching
objects
of
these
light
groups.
The
object
“external
input”
of
the
second
light
group
must
be
connected
to
the
push
button,
which
sends
the
requirement
for
the
blackboard
light.
The
push
button
must
send
an
1
‐
signal
to
the
object.
