INSTALLATION
Step
Four
OMEGA
ENGINEERING's
LVP
‐
51
‐
R
level
switch
may
be
installed
anywhere
on
a
tank
wall
using
the
PE
(LVP
‐
91)
or
PP
(LVP
‐
92)
bracket
that
the
switch
slides
into.
The
bracket
comes
with
adhesive
on
the
tank
side
that
is
sufficient
to
hold
the
sensor
in
position
temporarily
while
the
installation
is
tested,
but
for
permanent
installation
the
bracket
must
be
welded,
glassed
or
strapped
to
the
tank.
Extra
brackets
are
available
from
OMEGA
ENGINEERING,
so
that
the
level
switch
may
be
moved
to
different
locations
on
the
tank
by
sliding
it
into
other
brackets.
Attach
the
bracket
to
the
tank:
1.
Determine
whether
the
tank
is
PP
or
PE.
The
slide
‐
in
fitting
shipped
with
the
sensor
is
determined
by
the
part
number.
If
necessary,
obtain
an
additional
bracket.
2.
Determine
the
mounting
location
for
the
level
switch.
The
point
of
actuation
(where
the
sensor
will
send
a
“wet”
signal)
is
most
often
at
the
center
of
the
sensor;
however
the
actual
Point
of
Actuation
(POA)
may
differ
depending
on
the
application
liquid
and
tank
wall
characteristics.
After
positioning
the
fitting
to
check
clearances,
etc.,
remove
the
paper
protective
strips
from
the
adhesive
of
the
bracket.
3.
Press
the
bracket
into
place.
The
adhesive
provides
a
seal
between
the
sensor
and
the
tank
wall,
and
will
hold
it
in
place
during
testing
and
installation.
If
desired,
the
sensor
may
be
installed
temporarily
without
welding
the
fitting
to
the
wall.
If
several
different
locations
must
be
tried
before
permanent
installation,
use
double
‐
sided
foam
stick
tape
designed
for
PP
or
PE.
4.
After
the
sensor
has
been
tested
to
verify
the
POA,
weld,
glass
or
strap
the
bracket
to
the
tank
using
standard
industrial
plastic
techniques.
Special
note
for
small
round
tanks:
The
bracket
may
be
attached
to
small,
round
tanks,
as
long
as
the
majority
of
the
bracket
is
firmly
attached
to
the
wall.
However,
extreme
installations
may
affect
the
switches
performance.
Mount
the
sensor
in
the
bracket:
1.
Slide
the
sensor
into
the
bracket.
2.
After
trimming
the
sensor
wire
to
length
if
needed
by
the
installation,
thread
the
sensor
wire
into
a
plastic
flexible
conduit
with
a
1/2"
male
fitting.
Screw
the
conduit
into
the
sensor,
being
careful
not
to
cross
the
threads.
Do
not
over
tighten
the
conduit
in
the
sensor
as
this
may
break
the
fitting.
Such
damage
is
not
covered
by
the
warranty.
Take
care
while
pulling
the
wire
through
conduit
that
no
excessive
tension
is
placed
on
the
sensor
end
of
the
wire,
so
that
the
wire
is
not
broken
from
the
sensor
housing.
3.
Connect
the
sensor
wire
to
the
controller
following
the
instructions
in
its
manual.
See
the
following
Wiring
Section
for
detailed
wiring
instructions.
