Procedures

Installing

the

PE

Assembly

Follow

the

steps

below

to

install

the

programming

electronics

assembly

in

the

2500.

1.

Turn

off

the

2500

and

remove

the

power

cord.

CAUTION:

Pins

in

the

pin

block

are

delicate

and

could

be

damaged

if

they

hit

components

mounted

on

the

underside

of

the

main

plate.

The

pin

block

cover

ensures

that

these

pins

are

not

damaged

while

you

are

removing

or

reinstalling

the

PE

assembly.

2.

Carefully

slide

the

PE

assembly

onto

the

clamp

assembly.

Figure

7-7

shows

the

two

tracks

on

the

clamp

assembly

that

fit

into

grooves

on

the

pin

block.

3.

Install

the

retaining

bar

and

its

two

hex

screws

to

connect

the

PE

assembly

to

the

clamp

assembly.

4.

Reconnect

the

two

optic

cables

(S-24

and

C-25).

5.

Reconnect

the

two

of

the

four

air

lines

(one

red

and

one

blue)

to

the

rear

quick

connects.

6.

Hold

the

programming

module

clamp

assembly

in

place

and

reinstall

the

six

7/64-inch

hex

screws.

7.

Reconnect

the

two

remaining

air

lines

(one

red

and

one

blue)

to

the

front

quick

connects.

8.

Reconnect

all

of

the

remaining

cables.

CAUTION:

When

you

connect

the

cables,

be

careful

to

use

the

correct

polarity

of

the

cables

to

the

connectors.

Reversing

or

misaligning

a

cable

could

damage

components

on

the

2500.

9.

Connect

the

2500

to

a

compressed

air

source

and

check

for

air

leaks

by

listening

for

a

hissing

sound.

10.

When

you

determine

that

there

aren't

any

air

leaks,

lower

the

main

plate.

11.

Tighten

the

two

corner

screws

in

the

main

plate

(see

Figure

7-3).

Motor

Replacement

These

procedures

explain
