About
This
Manual:
PLEASE
READ
THE
ENTIRE
MANUAL
PRIOR
TO
INSTALLING
OR
USING
THIS
PRODUCT.
This
manual
includes
information
on
the
continuous
relay
controller
from
FLOWLINE:
LC52
‐
1001
series.
User’s
Responsibility
for
Safety:
FLOWLINE
manufactures
several
models
of
controller,
with
different
mounting
and
switching
configurations.
It
is
the
user’s
responsibility
to
select
a
controller
model
that
is
appropriate
for
the
application,
install
it
properly,
perform
tests
of
the
installed
system,
and
maintain
all
components.
Electrical
Shock
Hazard:
It
is
possible
to
contact
components
on
the
controller
that
carry
high
voltage,
causing
serious
injury
or
death.
All
power
to
the
controller
and
the
relay
circuit(s)
it
controls
should
be
turned
OFF
prior
to
working
on
the
controller.
If
it
is
necessary
to
make
adjustments
during
powered
operation,
use
extreme
caution
and
use
only
insulated
tools.
Making
adjustments
to
powered
controllers
is
not
recommended.
Wiring
should
be
performed
by
qualified
personnel
in
accordance
with
all
applicable
national,
state
and
local
electrical
codes.
Flammable
or
Explosive
Applications
:
The
LC52
series
continuous
relay
controllers
should
not
be
used
with
explosive
or
flammable
liquids,
which
require
an
intrinsically
safe
or
explosion
proof
rating.
If
you
are
unsure
of
the
suitability
of
a
controller
for
your
installation,
consult
your
Flowline
representative
for
further
information.
Install
In
a
Dry
Location:
The
controller
housing
is
not
designed
to
be
immersed.
When
installed
properly,
it
should
be
mounted
in
such
a
way
that
it
does
not
normally
come
into
contact
with
liquid.
Refer
to
an
industry
reference
to
ensure
that
compounds
that
may
splash
onto
the
controller
housing
will
not
damage
it.
Such
damage
is
not
covered
by
the
warranty.
Relay
Contact
Rating:
The
relay
is
rated
for
a
12
amp
resistive
load.
Many
loads
(such
as
a
motor
during
start
‐
up
or
incandescent
lights)
are
reactive
and
may
have
an
inrush
current
characteristic
that
may
be
10
to
20
times
their
steady
‐
state
load
rating.
The
use
of
a
contact
protection
circuit
may
be
necessary
for
your
installation
if
the
12
amp
rating
does
not
provide
an
ample
margin
for
such
inrush
currents.
In
critical
applications,
redundant
backup
systems
and
alarms
must
be
used
in
addition
to
the
primary
system.
Such
backup
systems
should
use
different
sensor
technologies
where
possible.
