Troubleshooting

 

 

If

 

the

 

MS2600E

 

does

 

not

 

seem

 

to

 

perform

 

as

 

expected,

 

check

 

the

 

following

 

items:

 

 

 

CAUTION:

  

Before

 

performing

 

any

 

tests

 

or

 

maintenance

 

on

 

the

 

MS2600E,

 

ensure

 

that

 

all

 

hazardous

 

area

 

requirements

 

are

 

met.

 

 

 

1.

 

Ensure

 

that

 

the

 

probe

 

is

 

operational

 

and

 

is

 

not

 

completely

 

corroded.

 

This

 

can

 

be

 

done

 

in

 

two

 

ways.

 

a.

 

Test

 

the

 

probe

 

with

 

a

 

portable

 

ER

 

meter

 

if

 

available.

 

b.

 

Test

 

the

 

probe

 

with

 

a

 

portable

 

resistance

 

or

 

continuity

 

meter

 

as

 

follows:

 

i.

 

Connect

 

one

 

test

 

lead

 

to

 

pin

 

‘A’

 

of

 

the

 

probes

 

6

‐

pin

 

connector.

 

ii.

 

Measure

 

continuity

 

to

 

each

 

of

 

the

 

other

 

pins.

  

There

 

should

 

be

 

continuity

 

(low

 

resistance)

 

to

 

each

 

pin.

 

NOTE:

  

Continuity

 

on

 

each

 

pin

 

does

 

not

 

ensure

 

that

 

the

 

probe

 

is

 

good.

  

However,

 

if

 

you

 

find

 

an

 

open

 

circuit

 

on

 

any

 

pins

 

then

 

it

 

is

 

almost

 

certain

 

that

 

the

 

probe

 

is

 

bad

 

and

 

should

 

be

 

replaced.

 

2.

 

Ensure

 

that

 

the

 

Probe

 

Selection

 

Switches

 

are

 

set

 

correctly

 

for

 

the

 

probe

 

being

 

used.

  

Confirm

 

the

 

probe

 

type,

 

and

 

refer

 

to

 

Table

 

2

 

on

 

page

 

9

 

to

 

verify

 

the

 

appropriate

 

switch

 

settings.

 

3.

 

Perform

 

a

 

visual

 

inspection

 

of

 

the

 

circuit

 

boards

 

to

 

look

 

for

 

any

 

signs

 

of

 

mechanical

 

or

 

electrical

 

damage.

 

4.

 

Ensure

 

that

 

all

 

electrical

 

cables

 

and

 

wiring

 

are

 

in

 

good

 

condition.

 

5.

 

Ensure

 

that

 

all

 

electrical

 

contacts

 

are

 

secure

 

and

 

free

 

of

 

corrosion.

 

6.

 

Ensure

 

that

 

there

 

is

 

adequate

 

supply

 

voltage

 

at

 

the

 

4

‐

20mA

 

Current

 

Loop

 

Connector.

 

7.

 

Verify

 

that

 

the

 

supply

 

voltage

 

polarity

 

is

 

correct.

 

8.

 

If

 

there

 

is

 

insufficient

 

supply

 

voltage

 

on

 

the

 

4

‐

20mA

 

Current

 

Loop

 

Connector,

 

check

 

the

 

safety

 

barrier

 

(if

 

applicable)

 

for

 

a

 

blown

 

fuse

 

or

 

any

 

other

 

failure.

 

9.

 

Test

 

the

 

MS2600E

 

using

 

the

 

supplied

 

Meter

 

Prover

 

(see

 

page

 

10.)

 

10.

 

Test

 

the

 

MS2600E

 

with

 

a

 

local

 

multi

‐

meter

 

or

 

loop

 

calibrator.

 

 

These

 

basic

 

checks

 

should

 

indicate

 

the

 

source

 

of

 

any

 

problem

 

(probe,

 

power

 

supply,

 

wiring,

 

etc…)

  

If

 

it

 

is

 

determined

 

that

 

the

 

MS2600E

 

is

 

malfunctioning,

 

or

 

if

 

you

 

need

 

further

 

assistance

 

in

 

troubleshooting,

 

contact

 

Metal

 

Samples

 

Technical

 

Support.

 

 

 

CAUTION:

  

If

 

the

 

MS2600E

 

shows

 

any

 

signs

 

of

 

damage

 

remove

 

it

 

from

 

service

 

immediately

 

and

 

consult

 

the

 

factory.
