"MAX"
BUTTON
FOR
DELIVERY
CONTROL
For
gasoline
and
diesel
dispensers,
the
"MAX"
button
on
the
display
of
the
dispenser
is
used
to
control
the
maximum
fuel
flow
in
the
delivery
hose,
especially
when
pumping
diesel
alternately
to
passenger
cars
(Q
lim
=
40
L/min)
and
trucks
(Q
max
=
80
L/min).
Functional
principle:
a)
When
lifting
the
delivery
nozzle
and
pumping
without
using
the
"MAX"
button,
the
fuel
runs
through
the
hose
with
a
preset
limited
flow
rate
Q
lim
which
prevents
frequent
switching
off
of
the
nozzle
due
to
the
resulting
foam,
especially
for
diesel.
b)
If
the
"MAX"
button
is
pressed
before
or
during
the
delivery
operation,
the
letter
"H"
or
the
pictogram
of
the
truck
appears
on
the
display
and
the
fuel
with
the
maximum
flow
Q
max
given
by
the
pump
used
flows
through
the
delivery
hose.
The
limited
flow
value
Q
lim
can
be
set
for
each
delivery
hose
using
the
counter
parameter.

"MIN"
BUTTON
FOR
DELIVERY
CONTROL
For
fuel
dispensers,
the
"MIN"
button
on
the
display
of
the
dispenser
is
used
to
control
the
fuel
flow
in
the
delivery
hose,
especially
when
pumping
fuel
into
small
motorcycles
or
small
containers
(Q
min
=
4
‐
6
L/min).
Functional
principle:
a)
Upon
lifting
up
the
delivery
nozzle
and
delivering
without
the
"MIN"
button,
the
fuel
flows
through
the
hose
with
the
preset
limited
flow
Q
min
.
b)
If
the
"MIN"
button
is
pressed
before
or
during
the
delivery
operation,
the
letter
"L"
or
the
motorcycle
pictogram
appears
on
the
display
and
the
fuel
with
the
set
minimum
flow
Q
min
flows
through
the
delivery
hose.
c)
When
the
"MIN"
button
is
pressed
again,
the
letter
"L"
disappears
on
the
display
and
the
dispenser
delivers
with
a
higher
flow
rate
again.
The
limited
flow
value
Q
lim
can
be
set
for
each
delivery
hose
using
the
