the
vapour/gasoline
ratio
must
be
equal
to
or
greater
than
0.95
but
less
than
or
equal
to
1.05.
The
actual
operation
of
the
vapour
recovery
system
is
indicated
on
the
display
of
the
dispenser
depending
on
the
type
of
display
used
either
by
the
display
segment
or
by
the
green
LED
or
by
the
two

A
malfunctioning
vapour
recovery
system

system
may

on

The
operation
of
the
vapour
recovery
system
can
be
automatically
monitored
by
a
control
unit
coupled
to
a
vapour
flow
sensor
located
on
the
return
pipe
in
the
dispenser,
e.g.,
VAPORIX
(FAFNIR)
or
Vareco
Plus
(TST).
The
vapour
monitoring
system
compares
the
volume
of
extracted
vapours
with
the
volume
of
filled
fuel
at
each
delivery
and
stores
the
data
in
the
control
unit.
If
the
vapour/gasoline
ratio
is
not
within
the
specified
limits
(95%
to
105%),
it
sends
a
signal
to
the
counter
of
the
dispenser
which,
if
the
defect
is
not
removed
within
72
hours,
does
not
allow
gasoline
to
be
delivered
from
the
dispenser.
According
to
European
Directive
2009/126/EC
Art.
5,
the
vapour
recovery
system
must
be
officially
inspected
at
least
once
a
year.
If
the
dispenser
is
equipped
with
monitoring
of
the
vapour
recovery
system,
the
official
examination
is
necessary
at
least
every
three
years.
NOTICE
In
case
of
suspicion
of
malfunctioning
of
the
recovery
or
detection
of
malfunctioning
of
the
signalling,
the
operator
is
obliged
to
notify
this
fact
immediately
to
the
service
organization
to
carry
out
the
inspection
and
to
remedy
the
defect.

VAPOUR
RECOVERY
SYSTEM
TEST
The
PDEX
or
PDEX5
dispenser
counter
allows
you
to
perform
a
simple
test
of
the
vapour
recovery
system
of
a
dispenser
according
to
EN

article
5.4.
and
a
simple
functional
test
without
delivering
fuel
or
shutting
down
the
dispenser
communication
with
the
POS.
It
is
therefore
a
so
‐
called
dry
test,
in
which
the
fuel
flow
is
only
simulated.
Only
a
manager
service
remote
controller
is
required
to
run
the
test.
To
measure
the
air
flow
through
the
fume
extraction
system,
a
gas
meter
with
a
dispensing
nozzle
adapter
must
be
used,
for
example

Test
progress:
1)
Before
performing
the
test,
it
is
necessary
that
the
filling
point
is
at
idle
state,
i.e.,
all
nozzles
are
in
nozzle
boots
and
the
last
transaction
paid.
Press
the
<8>
key
on
the
manager
or
service
remote
control
to
start
the
test
mode.
The
quantity
display
line
displays
the
value
of
the
simulated
fuel
flow,
whose
default
value
Q
=
38L/min.
If
we
want
to
set
a
different
value
of
the
simulated
fuel
flow,
then
