Connecting
the
delivery
nozzle
with
an
adapter
and
gas
meter
A
simple
function
test
is
used
to
verify
that
all
components
of
the
vapour
recovery
system
are
working,
i.e.,
the
vacuum
pump
is
pumping,
the
VR
pipes
are
not
clogged,
the
solenoid
valve
and
the
dispensing
nozzle
valve
open.
Procedure
for
a
simple
function
test
of
the
vapour
recovery
system:
1)
All
nozzles
on
the
tested
part
of
the
dispenser
are
hung
up
and
the
filling
point
has
a
completed
and
paid
filling
(transaction).
Pick
up
the
nozzle
for
which
is
necessary
to
verify
the
functionality
of
the
vapour
recovery
and
instead
quickly
insert
a
spare
nozzle
or
magnet
so
that
the
delivery
does
not
start
and
the
dispenser
remains
at
idle
status.
2)
Attach
an
adapter
‐
whistle
(Quick
Tester
GR92
‐
see
Picture
83)
to
the
picked
‐
up
dispensing
nozzle.
Then
hang
the
dispensing
nozzle
downwards
with
the
outlet
spout
to
open
the
internal
ON/OFF
vapour
recovery
valve.
3)
Press
the
<8>
key
on
the
manager
or
service
remote
controller.
The
screen
(1)
will
appear
on
the
display
‐
see
previous
test.
4)
Press
the
<E>
key.
The
vacuum
pump
starts
for
the
time
set
in
parameter
P11
(factory
setting
=
60
seconds).
At
the
same
time,
the
corresponding
proportional
valve
(VRA
or
VRB)
opens
and
air
flows
through
the
dispensing
nozzle.
The
set
time
up
to
0
will
be
counted
down
on
the
unit
price
display
line.
5)
At
the
end
of
the
test
period,
the
test
ends,
i.e.,
the
vacuum
pump
is
switched
off
and
the
valve
is
closed.
The
new
test
can
be
started
again
by
pressing
the
<E>
key.
Test
evaluation:
The
vapour
recovery
system
is
functional
if
a
whistling
sound
is
heard
from
the
adapter
during
the
test,
see
Picture
83
‐
which
is
proof
of
the
air
flowing
through
the
entire
recuperation
system.
NOTE
The
Quick
Tester
GR
92
adapter
is
manufactured
by
ELAFLEX
(Germany).
If
an
adapter
is
not
available,
the
functionality
of
the
recuperation
system
can
also
be
verified
with
a
plastic
bag,
which
is
wrapped
around
the
neck
of
the
nozzle
and
which
deforms
(vacuums)
during
the
test.
