To

 

mount

 

the

 

MS2600E:

 

 

1.

 

Align

 

the

 

keyways

 

of

 

the

 

transmitter

 

and

 

probe

 

connectors.

 

2.

 

Insert

 

the

 

transmitter

 

connector

 

plug

 

fully

 

into

 

the

 

probe

 

connector

 

receptacle.

 

3.

 

Secure

 

the

 

transmitter

 

to

 

the

 

top

 

of

 

the

 

probe

 

by

 

tightening

 

the

 

coupling

 

nut.

 

NOTE:

 

Hand

‐

tight

 

is

 

sufficient.

  

Do

 

not

 

over

‐

tighten

 

the

 

coupling

 

nut.

 

NOTE:

  

Never

 

force

 

the

 

connectors

 

to

 

mate.

  

If

 

there

 

is

 

resistance,

 

stop

 

and

 

check

 

for

 

bent

 

pins

 

on

 

the

 

probe

 

and

 

for

 

foreign

 

material

 

in

 

the

 

female

 

sockets

 

of

 

the

 

transmitter

 

connector.

  

Gently

 

straighten

 

any

 

bent

 

pins

 

and

 

clear

 

any

 

foreign

 

material

 

that

 

may

 

be

 

found.

Mounting

 

When

 

it

 

is

 

not

 

practical

 

to

 

direct

‐

probe

 

mount

 

the

 

MS2600E,

 

the

 

unit

 

can

 

be

 

remote

 

mounted

 

instead.

  

In

 

this

 

case

 

the

 

instrument

 

is

 

mounted

 

to

 

a

 

separate

 

mounting

 

pole

 

using

 

the

 

optional

 

Remote

 

Mounting

 

Hardware

 

Kit.

  

The

 

MS2600E

 

is

 

then

 

connected

 

to

 

the

 

ER

 

probe

 

via

 

the

 

optional

 

probe

 

extension

 

cable.

  

When

 

possible,

 

the

 

MS2600E

 

should

 

be

 

mounted

 

within

 

10’

 

(3m)

 

of

 

the

 

probe

 

to

 

keep

 

the

 

probe

 

cabling

 

short

 

and

 

minimize

 

signal

 

degradation.

Connections

 

The

 

MS2600E

 

current

is

 

made

 

via

 

the

 

external

 

6

‐

pin

 

circular

 

connector

 

as

 

shown

 

below.

  

This

 

hermetically

 

sealed

 

connector

 

prevents

 

moisture

 

ingress,

 

and

 

eliminates

 

the

 

need

 

for

 

internal

 

wiring

 

by

 

an

 

operator

 

which

 

reduces

 

the

 

risk

 

of

 

damage

 

to

 

the

 

circuit.
