E6
‐
VLV
CONTROL
CARD
FOR
ONCOMING
TRAFFIC
LIGHT
The
E6
‐
VLV
oncoming
traffic
light
control
card
is
used
to
control
traffic
on
ramps
and
in
other
such
places
where
traffic
can
proceed
in
one
direction
at
a
time.
Areas
of
application
are
car
parks
and
other,
similar
places
with
an
entrance
ramp
that
is
the
width
of
a
single
vehicle
and
that
must
be
reserved
based
on
the
direction
of
traffic.
The
ramp
has
a
door
or
equivalent,
or,
alternatively,
both
a
door
and
a
barrier.
In
such
cases,
the
door
is
used
at
night
and
the
barrier
during
the
daytime.
There
are
red/green
traffic
lights
at
both
ends
of
the
ramp,
which
are
given
control
signals
by
the
card
upon
receipt
of
a
reservation
request.
The
lights
are
controlled
either
with
coils
or
the
equivalent
or
by
control
devices
at
the
ends
of
the
ramp
with
a
potential
‐
free
contact.
It
is
essential
that
the
control
devices
be
direction
‐
sensing.
Direction
‐
sensing
is
imple
‐
mented
via
software.
In
order
for
the
direction
‐
sensing
to
work
correctly,
the
vehicle
must
encounter
the
two
sensing
con
‐
trol
devices
in
the
correct
order
and
be
in
their
area
of
detection
at
the
same
time
(for
example,
two
vehicle
detector
coils
at
a
distance
of
around
one
metre
from
each
other).
Incoming
direction
sensing
is
connected
to
connectors
15,
16,
and
17,
with
17
being
common.
Connectors
15
and
17
are
connected
first,
and
then
16
and
17.
The
green
diodes
light
up
in
the
fol
‐
lowing
order:
first
H1
and
then
H2
.
Outgoing
direction
sensing
is
connected
to
connectors
20,
21,
and
22,
with
22
common.
Connectors
22
and
21
are
connected
first,
and
then
22
and
20.
The
green
diodes
light
up
in
the
following
order:
first
H5
and
then
H4
.
If
reservation
requests
are
implemented
with,
for
example,
buttons
or
the
equivalent,
with
a
potential
‐
free
con
‐
tact,
incoming
traffic
reservation
is
connected
to
connectors
18
and
19,
and
when
the
contact
closes,
green
diode
H3
is
illu
‐
minated.
Correspondingly,
outgoing
traffic
reservation
is
connected
to
connectors
29
and
30,
and
when
the
contact
closes,
green
diode
H8
lights
up.
If
the
controller
includes
the
E6
‐
6
‐
02/3E
service
terminal
and
the
controller
receives
a
reservation
request
from
the
incom
‐
ing
traffic
control
device,
the
display
reads
‘OU
b’
for
a
moment,
or
‘OU
t’
when
the
reservation
request
comes
from
a
direc
‐
tion
‐
sensing
control.
The
corresponding
texts
for
outgoing
traffic
are
‘
IN b
’
and
‘
IN t
’.
The
operation
of
the
E6
‐
VLV
card
is
controlled
via
a
flat
cable
directly
from
the
bus
connector
of
the
E6
‐
2L
card.
The
pro
‐
gramming
required
for
light
control
with
the
E6
‐
VLV
card
can
be
done
using
the
jumpers
of
the
X12
connectors.
The
LEDs
indicate
operation.
Perform
duration
settings
with
rotary
switches
S1
and
S2
,
relays,
and
required
terminal
blocks
for
the
lights
and
controls.
OPERATION
Select
the
light
control
method
with
jumpers
1
and
2
of
connector
X12
.
If
the
controller
includes
the
E6
‐
6
‐
02/3E
service
terminal,
the
text
‘
A402
’
and
the
selected
control
method
are
shown
briefly
on
the
display.

WARNING
AND
TRAFFIC
LIGHTS
Control
method
1:
A
red
light
is
on
at
both
ends
of
the
ramp.
A
reservation
request
causes
the
green
light
to
be
illuminated
for
the
driving
di
‐
rection
and
turns
off
the
red
light
if
there
are
no
outstanding
reservations
from
the
opposite
direction.
Also,
the
door
is
sent
an
automatic
open
command.
The
light
changes
back
to
red
after
the
time
set
with
jumpers
5
and
6
of
connector
X12
.
A
new
reservation
request
extends
the
illumination
of
the
green
light
and
sends
a
new
open
command
to
the
door.
If
there
is
a
constant
queue
and
there
are
no
reservation
requests
from
the
opposite
direction,
the
green
light
stays
on
constantly,
on
the
assumption
that
each
vehicle
generates
a
reservation
request.
