PRIOR

 

TO

 

INSTALLING

 

OR

 

USING

 

THIS

 

PRODUCT.

   

This

 

manual

 

includes

 

information

 

on

 

the

 

Series

 

ULS

 

Ultrasonic

 

Level

 

Switch,

 

controller

 

and

 

transmitter

 

from

 

Dwyer

 

Instruments,

 

Inc.

 

Please

 

refer

 

to

 

the

 

part

 

number

 

located

 

on

 

the

 

switch

 

label

 

to

 

verify

 

the

 

exact

 

model

 

configuration,

 

which

 

you

 

have

 

purchased.

   

 

User’s

 

Responsibility

 

for

 

Safety:

   

Dwyer

 

Instruments,

 

Inc

 

manufactures

 

a

 

broad

 

range

 

of

 

level

 

sensing

 

technologies.

 

While

 

each

 

of

 

these

 

sensors

 

is

 

designed

 

to

 

operate

 

in

 

a

 

wide

 

variety

 

of

 

applications,

 

it

 

is

 

the

 

user’s

 

responsibility

 

to

 

select

 

a

 

sensor

 

model

 

that

 

is

 

appropriate

 

for

 

the

 

application,

 

install

 

it

 

properly,

 

perform

 

tests

 

of

 

the

 

installed

 

system,

 

and

 

maintain

 

all

 

components.

 

The

 

failure

 

to

 

do

 

so

 

could

 

result

 

in

 

property

 

damage

 

or

 

serious

 

injury.

  

 

Proper

 

Installation

 

and

 

Handling:

  

Only

 

professional

 

staff

 

should

 

install

 

and/or

 

repair

 

this

 

product.

  

Install

 

the

 

transmitter

 

with

 

the

 

included

 

FKM

 

gasket

 

and

 

never

 

over

 

tighten

 

the

 

transmitter

 

within

 

the

 

fitting.

  

Always

 

check

 

for

 

leaks

 

prior

 

to

 

system

 

start

‐

up.

 

 

Wiring

 

and

 

Electrical:

 

 

A

 

supply

 

voltage

 

of

 

12

 

to

 

28

 

VDC

 

is

 

used

 

to

 

power

 

the

 

Series

 

ULS.

  

Electrical

 

wiring

 

of

 

the

 

transmitter

 

should

 

be

 

performed

 

in

 

accordance

 

with

 

all

 

applicable

 

national,

 

state,

 

and

 

local

 

codes.

  

Note:

 

Series

 

ULS

 

uses

 

latching

 

relays.

  

When

 

power

 

is

 

removed

 

to

 

the

 

sensor,

 

the

 

relays

 

will

 

remain

 

in

 

their

 

last

 

state.

  

Ex:

 

If

 

the

 

relay

 

is

 

energized,

 

when

 

power

 

is

 

removed,

 

the

 

relay

 

will

 

remain

 

in

 

an

 

energized

 

state.

  

 

Material

 

Compatibility:

   

The

 

enclosure

 

is

 

made

 

of

 

Polycarbonate

 

(PC).

   

The

 

transducer

 

is

 

made

 

of

 

Polyvinylidene

 

Fluoride

 

(PVDF).

  

Make

 

sure

 

that

 

the

 

model,

 

which

 

you

 

have

 

selected,

 

is

 

chemically

 

compatible

 

with

 

the

 

application

 

media.

   

 

Enclosure:

 

 

While

 

the

 

transmitter

 

housing

 

is

 

liquid

‐

resistant

 

the

 

Series

 

ULS

 

is

 

not

 

designed

 

to

 

be

 

operational

 

when

 

immersed.

  

It

 

should

 

be

 

mounted

 

in

 

such

 

a

 

way

 

that

 

the

 

enclosure

 

and

 

transducer

 

do

 

not

 

come

 

into

 

contact

 

with

 

the

 

application

 

media

 

under

 

normal

 

operational

 

conditions.

   

Safety

 

Installation

 

should

 

be

 

done

 

by

 

properly

 

trained

 

staff

 

Supply

 

voltage

 

should

 

never

 

exceed

 

a

 

maximum

 

of

 

28

Make

 

sure

 

the

 

sensor

 

is

 

chemically

 

compatible

system

 

that

 

accommodates

 

the

 

possibility

 

of

failure

  

This

 

sensor

 

should

 

not

 

be

recommends

 

the

 

use

 

of

 

redundant

 

backup

 

systems

 

and

 

alarms

 

in

environments.

 

 

Warning:

 

Always

 

use

 

the

 

FKM

 

gasket

 

when

 

installing

 

the

 

Series

 

ULS,

 

and

 

make
