PRIOR
TO
INSTALLING
OR
USING
THIS
PRODUCT.
This
manual
includes
information
on
the
LVCN
‐
40
Series
level
indicator
from
OMEGA
ENGINEERING.
Please
refer
to
the
part
number
located
on
the
switch
label
to

the
exact
model
configuration,
which
you
have
purchased.
User’s
Responsibility
for
Safety:
OMEGA
ENGINEERING
manufactures
a
broad
range
of
level
sensing
technologies.
While
each
of
these
sensors
is
designed
to
operate
in
a
wide
variety
of
applications,
it
is
the
user’s
responsibility
to
select
a
sensor
model
that
is
appropriate
for
the
application,
install
it
properly,
perform
tests
of
the
installed
system,
and
maintain
all
components.
The
failure
to
do
so
could
result
in
property
damage
or
serious
injury.
Proper
Installation
and
Handling:
Only
professional
staff
should
install
and/or
repair
this
product.
Install
the
level
indicator
with
the
included
locking
nut
and
never
over
tighten
the
indicator
within
the
installation.
Always
check
for
leaks
prior
to
system
start
‐
up.
Wiring
and
Electrical:
A
supply
voltage
of
12
to
28
VDC
is
used
to
power
the
LVCN
‐
40
Series
and
the
LVCN
‐
414,
LVCN
‐
210
&
LVCN
‐
318
Series
sensor.
Electrical
wiring
of
the
transmitter
should
be
performed
in
accordance
with
all
applicable
national,
state,
and
local
codes.
Material
Compatibility:
The
enclosure
is
made
of
Polycarbonate
(PC)
with
the
Cable
made
of
Polyurethane
and
the
Buttons
made
of
silicon
rubber.
Make
sure
that
the
model,
which
you
have
selected,
is
chemically
compatible
with
the
application
media.
Enclosure:
While
the
level
indicator
housing
is
liquid
‐
resistant
the
LVCN
‐
40
Series
is
not
designed
to
be
operational
when
immersed.
It
should
be
mounted
in
such
a
way
that
the
enclosure
and
level
indicator
do
not
come
into
contact
with
the
application
media
under
normal
operational
conditions.
Make
a
Fail
‐
Safe
System:
Design
a
fail
‐
safe
system
that
accommodates
the
possibility
of
LVCN
‐
414,
LVCN
‐
210
&
LVCN
‐
318
Series/LVCN
‐
40
Series
and/or
power
failure.
OMEGA
ENGINEERING
recommends
the
use
of
redundant
backup
systems
and
alarms
in
addition
to
the
primary
system.
Flammable,
Explosive
or
Hazardous
Applications:
LVCN
‐
40
Series
should
not
be
used
within
classified
hazardous
environments.
Safety
Installation
should
be
done
by
properly
trained
staff
Supply
voltage
should
never
exceed
a
maximum
of
28
VDC
Make
sure
the
sensor
is
chemically
compatible
with
your
application
Design
a
fail
‐
safe
system
that
accommodates
the
possibility
of
sensor
and/or
power
failure
This
sensor
should
not
be
used
in
