GETTING
STARTED
(continued)
Step
Four
The
LC80
Series
may
be
used
with
almost
any
Flowline
flow
with
an
N
‐
channel
(ends
in
“
‐
_
_
_
2”)
or
relay
(ends
in
“
‐
_
_
_
5”)
output.
The
relay
is
a
single
pole,
double
throw
type;
the
controlled
device
can
be
connected
to
either
the
normally
open
or
normally
closed
side
of
the
relay.
A
time
delay
from
0
to
60
seconds
can
be
set
before
the
relay
responds
to
the
sensor
input.
Typical
applications
for
the
LC80
Series
are
pump
protection,
no
‐
flow
indication
or
chemical
injection.
Guide
to
Controls:
Below
is
a
listing
and
the
location
of
the
different
components
for
the
controller:
1.
Power
indicator:
This
green
LED
lights
when
AC
power
is
ON.
2.
Relay
indicator:
This
red
LED
will
light
whenever
the
controller
energizes
the
relay,
in
response
to
the
proper
condition
at
the
sensor
input(s)
and
after
the
time
delay.
3.
AC
Power
terminals:
Connection
of
120
VAC
power
to
the
controller.
The
setting
may
be
changed
to
240
VAC
if
desired.
This
requires
changing
internal
jumpers;
this
is
covered
in
the
Installation
section
of
the
manual.
Polarity
(neutral
and
hot)
does
not
matter.
4.
Relay
terminals
(NC,
C,
NO):
Connect
the
device
you
wish
to
control
(pump,
alarm
etc.)
to
these
terminals:
supply
to
the
COM
terminal,
and
the
device
to
the
NO
or
NC
terminal
as
required.
The
switched
device
should
be
a
non
‐
inductive
load
of
not
more
than
10
amps;
for
reactive
loads
the
current
must
be
derated
or
protection
circuits
used.
When
the
red
LED
is
ON
and
the
relay
is
in
the
energized
state,
the
NO
terminal
will
be
closed
and
the
NC
terminal
will
be
open.
5.
Time
delay:
Use
potentiometer
to
set
delay
from
0.15
to
60
seconds.
Delay
occurs
during
switch
make
and
switch
break.
6.
Input
indicators:
Use
these
LEDs
for
indicating
Flow
or
No
‐
Flow
status
of
switch.
When
switch
is
Closed,
LED
will
be
Amber.
When
switch
is
Open,
LED
will
either
be
OFF.
Note:
Consult
the
manual
for
the
flow
switch
to
determine
exact
wiring
as
well
as
switch
polarity
(Open
or
Closed
during
Flow).
7.
Invert
switch:
This
switch
reverses
the
logic
of
the
relay
control
in
response
to
the
switch:
conditions
that
used
to
energize
the
relay
will
now
de
‐
energize
the
relay
and
vice
versa.
8.
Latch
switch
(LC82
series
only):
This
switch
determines
how
the
relay
will
be
energized
in
response
to
either
one
input
(Input
2A)
or
two
inputs
(Inputs
2A
and
2B).
When
LATCH
is
OFF,
the
relay
responds
to
sensor
Input
2A
only;
when
LATCH
is
ON,
the
relay
will
energize
or
de
‐
energize
only
when
both
switches
(2A
and
2B)
are
in
the
same
state
(both
open
or
both
closed).
Note:
In
a
majority
of
flow
/
no
‐
flow
applications,
the
latch
will
be
turned
OFF.
9.
Input
terminals:
Connect
the
switch
wires
to
these
terminals:
(+)
is
a
24
VDC,
100
mA
power
supply,
(
‐
)
is
the
return
path
from
the
sensor
and
(S)
is
a
powered
switch
input
(14
VDC,
25mA).
Consult
the
flow
switch
manual
for
switch
polarity
(Ex:
Open
or
Closed
for
Flow)
as
well
as
wiring
information.
