TaskLink

also

allows

you

to

download

device

data

from

a

file

on

your

PC.

TaskLink

sends

the

PE

information

on

the

data

file

format

and

then

downloads

the

file.

The

PE

translates

the

formatting

information

in

the

file,

discards

all

formatting

characters

and

stores

the

data

in

RAM.

The

PE

signals

TaskLink

when

it

completes

writing

the

file

data

into

RAM.

TaskLink

then

sends

the

“program”

command

to

the

PE

and

the

device

is

programmed.

Conditions

Requiring

Corrective

Action

To

run

the

diagnostic

tests

and

to

make

some

of

the

adjustments,

you

must

operate

the

2500

from

its

front

panel

in

local

mode.

You

cannot

run

the

tests

using

TaskLink.

To

access

the

front

panel

from

remote

mode,

press

LOWER

CASE

+

L.

To

return

to

remote

mode

after

completing

the

diagnostics

and

adjustments,

press

LOWER

CASE

十

R

from

the

Main

Menu.

Device

Jams

The

optics

detect

stopped

or

jammed

devices

and

alert

you

to

the

condition.

Some

common

causes

for

device

jams

are

listed

below.

•

The

track

width

is

not

adjusted

correctly

for

the

device

in

the

track.

•

A

partially

full

output

tube

was

inserted

in

the

tube

holder.

TaskLink

assumed

the

tube

was

empty

and

sent

too

many

devices

to

the

tube.

•

The

number

of

parts

per

tube

is

incorrect.

•

The

track

is

dirty

so

devices

cannot

travel

smoothly.

•

A

device

has

bent

leads

that

cause

it

to

become

wedged

in

the

narrow

track.

•

A

device

has

foreign

material

(such

as

residual

label

adhesive)

on

the

surface.

•

The

output

track

air

pressure

is

set

too

low

for

the

size

of

the

device.

•

The

transition

height

between

the

output

tracks

and

the

tubes

is

incorrect.

Adjust

the

output

transition

height

screw

(for

the

affected

track)

for

the

correct

tube

thickness.

If

a

jam

occurs

in

the

output

track

and

the

2500

stops

operating,

push

the

jammed

device

with

a

wood

or

plastic

pointer

into

the

tube.

When

you

free

the

device,

either

the

2500

resumes

operation

automatically

or

you

may

need

to

press

START

to

continue

operation.

If

a

device

does

not

move

easily

down

the

input

track

due

to

bent

pins

or

some

other

condition,

you

might

have

to

remove

that

device

from

the

input

track

and

resume

operation

by

pressing

START

or

by

restarting

the

Task.

If

a

device

falls

off

the

chuck,

replace

it,

press

START

and

follow

the

prompts

on

the

2500's

display.

If

the

system

times

out,

press

STOP

and

then

START.
