The

LC52

can

be

set

in

one

of

two

modes,

sourcing

and

sinking.

The

LC52

is

shipped

from

the

factory

in

the

sourcing

mode.

This

is

compatible

with

any

loop

powered

transmitter

such

as

the

EchoSonic

(LU23,

LU27,

LU28

&

LU29

series),

EchoSpan

follow

the

instructions

below.

1.

Remove

the

back

panel

of

the

controller

and

gently

slide the

printed

circuit

board

(PCB)

from

the

housing.

Use

caution

when

removing

the

PCB.

2.

Locate

jumpers

JWA

and

JWB

on

the

PCB.

3.

To

change

from

sourcing

to

sinking,

remove

jumper

from

JWA

and

place

on

JWB.

The

LC52

is

shipped

from

the

factory

in

the

sourcing

mode

(JWA

active).

4.

Gently

return

PCB

into

housing

and

replace

back

panel.

Note:

Loop

powered

devices

can

operate

in

either

the

souring

or

sinking

modes.

Repeater

Output:

The

isolated

repeater

output

reproduces

the

input

4

‐

20

mA

current

signal.

This

signal

can

be

repeated

to

any

other

device

that

accepts

a

4

20

mA

input,

such

as

a

PLC,

DCS,

SCADA,

chart

or

another

display.

The

repeated

4

20

mA

signal

is

not

an

excited

output.

An

external

power

supply

is

required

and

should

not

exceed

a

maximum

of

36

VDC.

See

the

wiring

diagram

to

the

right

for

instructions

in

wiring

all

three

components

(repeater

output,

power

supply

and

the

new

device)

in

series

with

each

other.
