VAC
Power
Input
Wiring:
Observe
the
POWER
SUPPLY
label
on
the
LC80
series.
The
label
identifies
the
power
requirement
(120
or
240
VAC)
and
the
terminal
wiring.
Note:
Polarity
does
not
matter
with
the
AC
input
terminal.
Relay
Input
Wiring:
The
relay
is
a
dry
‐
contact
single
pole,
double
throw
(SPDT)
type
rated
at
250
VAC,
10
Amps.
The
relay
is
designed
to
switch
power
on
and
off
to
a
device.
There
is
no
active
power
within
the
relay
contacts
alone.
Power
must
be
introduced
from
secondary
source
or
from
the
power
being
used
by
the
controller.
Power
from
a
secondary
source
Power
from
the
same
source
as
the
controller
The
two
terminal
Normally
Open
(NO)
and
Normally
Closed
(NC)
will
be
used
in
different
applications.
Remember
that
the
"normal"
state
is
when
the
relay
coil
is
de
‐
energized
and
the
Red
relay
LED
is
Off
/
de
‐
energized.
Both
terminals
share
the
Common
(C)
terminal.
When
relay
is
de
‐
energized,
C
to
NO
will
be
open
and
C
to
NC
will
be
closed.
When
relay
is
energized,
C
to
NO
will
be
closed
and
C
to
NC
will
be
open.
If
power
is
removed
to
the
controller,
the
relay
will
return
to
a
de
‐
energized
state.
Changing
from
120
to
240
VAC:
1.
Remove
the
back
panel
of
the
controller
and
gently
slide
the
printed
circuit
board
from
the
housing.
Use
caution
when
removing
the
PCB.
2.
Located
jumpers
JW1,
JW2
and
JW3
on
the
PCB.
3.
To
change
to
240
VAC,
remove
jumpers
from
JW1
and
JW2
and
place
a
single
jumper
across
JW3.
To
change
to
120
VAC,
remove
jumper
JW3
and
place
jumpers
across
JW1
and
JW2.
4.
Gently
return
PCB
into
housing
and
replace
back
panel.
