VAPOUR
RECOVERY
SYSTEM
HISTORY
(P33,
P34)
The
parameter
is
used
to
display
the
last
40
fillings
on
nozzles
with
activated
vapour
recovery
for
filling
point
A
(P33)
or
B
(P34).
Records
are
only
stored
if
the
internal
vapour
recovery
monitoring
system
is
activated.
After
switching
to
parameter
P33
(vapour
recovery
system
history
for
filling
point
A),
the
display
shows
the
vapour
recovery
values
for
the
last
delivery.
The
amount
display
line
shows
the
percentage
feedback
factor
value
to
one
decimal
place
(see
P36
for
more
information).
The
quantity
display
line
shows
the
vapour
/
fuel
ratio
in
percent
with
one
decimal
place.
After
pressing
the
<+>
key,
the
penultimate
filling
appears.
After
pressing
the
<E>
key,
the
date
and
time
of
the
end
of
the
saved
delivery
will
appear
on
the
display.

Example:
According
to
the
last
record
(00),
fuel
delivery
took
place
on
24.8.2021
at
12:51:01,
during
which
the
vapor
recovery
feedback
factor
was
98.0%
and
the
ratio
of
the
volume
of
extracted
vapours
to
the
volume
of
flowed
fuel
was
102.5%

AVERAGE
VALUE
OF
VAPOUR/FUEL
RATION
(P35)
The
parameter
is
used
to
display
the
average
value
of
the
ratio
of
the
volume
of
extracted
vapors
to
the
volume
of
fuel
dispensed.
The
average
is
calculated
from
the
last
40
fillings
for
filling
points
A
and
B.
After
switching
to
parameter
P35,
the
display
shows
the
average
volume
ratio
value
for
filling
point
A
(P35
‐
A).
The
quantity
display
line
shows
the
vapour/fuel
ratio
in
percent
with
one
decimal
place.
After
pressing
the
<+>
key,
the
average
ratio
value
for
filling
point
B
(P35
‐
B)
appears.

to
the

AVERAGE
VALUE
OF
VAPOUR
RECOVERY
FEEDBACK
FACTOR
(P36)
The
parameter
is
used
to
display
the
average
feedback
factor
of
the
vapour
recovery
system.
The
average
is
calculated
from
the
last
40
fillings
for
filling
points
A
and
B.
After
switching
to
parameter
P36,
the
display
shows
the
average
value
of
the
feedback
factor
for
filling
point
A
(P36
‐
A).
On
the
quantity
display
line,
there
is
a
percentage
factor
with
one
decimal
place.
After
pressing
the
<+>
key,
the
average
factor
value
for
filling
point
B
(P36
‐
B)
appears.
Parameter

feedback
factor
for

A
P36
‐
B
Average
value
of

Example:
The
average
value
of
the
vapour
recovery
feedback
factor
for
filling
point
A
is
98.0%
NOTE
The
average
value
should
be
between
95%
and
105%.
If
the
value
is
lower
than
95%,
it
probably
means
a
problem
with
the
vapor
recovery
vacuum
pump
or
dirt
in
the
VR
piping.
If
the
value
is
higher
than
105%,
then
the
regulation
(VR
solenoid
valve)
may
not
work
properly.
