the

recorder

selects

operation

for

either

115

or

230

volts.

The

three-conductor

power

cable

supplied

with

the

instrument

is

terminated

in

a

three-prong

polarized

male

connector

recommended

by

the

Electrical

Manu-

facturers'

Association

(NEMA).

The

third

contact

is

an

offset

round

pin,

added

toastandard

PROGRAMMING

THE

RECORDER.

The

recorder

can

be

programmed

to

accept

different

codes

if

the

proper

column

boards

are

installed.

The

column

boards

may

be

inter-mixed

if

desired.

The

standard

recorder

is

supplied

with

six

+1224

BCD

column

boards,

with

connectors

installed

to

accept

a

total

of

nine

column

boards.

If

more

than

nine

column

operation

is

desired,

J201

must

be

installed

with

the

connectors

that

attach

to

the

rear

of

the

column

boards

(PIIO-PIl5).

Normally

JIOl

supplies

data

to

column

boards

Al-A9,

but

connectors

PIOl-

PI09

can

be

connected

to

supply

data

to

any

of

the

column

boards

the

operator

desires.

J201

can

supply

data

to

any

of

the

remaining

column

boards.

Con-

nectors

PIIO-Pll5

can

be

connected

to

supply

data

to

six

column

boards.

3-6.

PROGRAMMING

THE

CONTROL

BOARD

(AI3).

Connectors

P20l

and

P202

supply

control

signals

to

If

only

'one

is

used,

the

board

connector

that

must

be

disconnected,

otherwise

the

When

the

is

disconnected,

the

associated

print

remains

in

the

Thus

a

is

required

from

REFERENCE

VOLTAGES.

Input

to

the

binaries

is

through

gates

which

are

controlled

by

two

dc

-biasing

signals

which

control

the

passage

of

transfer

pulses.

One

of

the

biasing

signals

is

the

BCD

data

input

and

the

other

is

a

reference

voltage.

The

transfer

pulses

are

internally-generated

within

the

recorder.

The

inputs

to

the

binaries

are

capacitively-coupled

and

may

be

floating

with

respect

to

chassis

ground.

The

reference

voltage

is

thus

required

to

establish

a

point

to

which

the

BCD

sig'nal

is

referred.

Two

reference

voltages

are

required

in

the

data

system

and

should

generally

be

the

REFERENCE

VOLTAGE

ADJUSTMENT.

Model

562A

The

input

voltage

applied

for

any

column

board

must

not

exceed

150

volts.

That

is

the

refe

renee

voltage

plus

theBCD

It1It

level

should

not

be

greater

than

150

volts.

For

instance,

if

the

BCD

swing

is

from

100

volts

(tiD"

level)

to

160

volts

(til"

level)

then

attenuation

must

be

introduced

to

reduce

the

"0"

level

to

94

volts

and

the

"1"

level

to

150

volts.

The

minus

reference

voltage

can

then

be

adjusted

for

94

volts.

The

plus

reference

level

must

then

be

adjusted

to

150

volts.

Before

a

reference

voltage

can

be

chosen,

the

"0"

and"

I"

levels

of

the

equip-

ment

supplying

the

BCD

signals

must

be

known.

For

instance

if

the

recorder

is

connected

toabinary

counter

with

a

-1248

code,

each

column

board

will

be

driven

byadecade

in

the

counter.

Sometimes

binaries

in

the

decades

have

different"

1"

and"

0"

levels,

thus

a

proper

reference

voltage

must

be

chosen.

If

the

column

board

is

a

-1248

code,

then

the

-reference

voltage

must

be

chosen

that

includes

the

"1"

levels

applied

to

the

A,

B,

C,

and

D

binaries.

A

+reference

voltage

must

be

chosen

that

will

include

the

"0"

levels

for

the

A,

B,

C,

and

D

binaries.

If

high

impedance

reference

levels

are

used

(above

5000

ohms),

suitable

by-

passing,

providing

a

time

constant

of

150

~s,

should

be

used.

If

the

BCD

drive

is

derived

from

an

unregulated

supply,

then

it

is

desirable

to

obtain

the

reference

voltage

from

the

same

unregulated

supply.

3-11.

POWER

SUPPLY

AND

INTERNAL

REFERENCE

VOLTAGES.

The

power

supply

board,

A16,

supplies

the

de

voltages

required

by

the

recorder.

The

power

supply

also

has

provisions

for

providing

reference

voltages

of

-9

to

+17

volts.

The

operator

can

select

a

value

of

resistors

or

breakdown

diodes

needed

to

provide

the

proper

reference

voltages.

Connectors

P301

and

P302

(optional)

supply

the

reference

voltages

to

the

column

boards.

When

using

an

external

reference

voltage,

connectors

P30l

and

P302

must

be

disconnected

from

the

power

supply

board

if

resistors

are

installed.

Unless

specified

by

the

customer,

resistors

are

not

installed.

The

proper

mounting

holes

are

in

the

power

board

and

the

operator

can

install

the

resistors

or

break-

down

diodes

required

to

give

the

desired

shunt

the

with

a

value

of

which

results

in

Potentiometer

recorders

having

less

may

be

used,

but

the

POTENTIOMETER

will

than

provide

less

than

100

millivolts

for

The

internal

is

approximately

2500

and

when

loaded

with

INTRODUCTION.

Section

Operation

of

the

is

dependent

uponaseries

of

timing

and

reference

volt-

ages.

The

timing

voltages

are

supplied

by

the

control

board

(Al3).

Reference

voltages

can

be

supplied

by

the

power

supply

(A14)

or

by

an

external

source.

The

following

paragraphs

will

describe

the

functions

of

various

circuits

in

the

recorder.

4-2.

CONTROL

BOARD

OPERATION.

Operation

of

the

recorder

is

dependent

upon

a

series

of

timing

voltages

developed

by

the

control

board.

Refer

to

the

functional

diagram,

figure

5-2.

Assume

the

data

source

initiates

a

print

command.

Print

Command

Binary

Number

and

immediately

supplies

the

data

source

withadisable

voltage.

Assume

Print

Command

Binary

Number

2

has

its

input

connector

arranged

so

only

one

print

is

required.

The

Print

Scan

Schmitt

is

in

the

proper

state

because

the

shutter

is

open.

The

Print

Scan

Schmitt

applies

the

proper

signal

to

the

"And"

Gate.

The

"And"

Gate

conducts

and

causes

the

Clutch

Binary

to

change

state.

The

clutch

solenoid

starts

to

energize.

When

the

Clutch

Binary

changes

state,

a

signal

is

applied

to

the

Delay

Multivi-

brator

(2MS).

The

output

of

the2ms

delay

multivibrator

produces

a

reset

pulse

which

is

applied

to

the

storage

binaries.

This

removes

stored

information

and

sets

the

storage

binaries

in

the

proper

state

to

receive

new

information.

The

output

of

the2ms

delay

multivibrator

is

also

applied

toa60

J-Ls

delay

multi-

vibrator.

The

output

of

the

60

J-LS

multivibrator

is

applied

to

the

storage

binary

gate

diodes

by

way

of

the+and-Transfer

Amplifiers,

then

data

transfer

takes

place.

The

output

of

the

60

f.LS

multivibrator

is

also

applied

to

the

Print

Command

Binaries

and

resets

them.

While

this

action

is

occurring,

the

clutch

solenoid

is

completing

its

pull-in

cycle.

When

the

clutch

solenoid

has

engaged

the

clutch,

the

clutch

will

remain

engaged

for

one

complete

revolution

of

the

clutch

assembly

because

of

mechanical

action.

As

the

clutch

assembly

rotates,

the

shutter

closes,

de-energizing

the

photo

conductor.

This

causes

the

schmitt

to

change

state,

initiating

the

scan

signal.

The

scan

signal

then

resets

the

clutch

binary

and

opens

the

Inhibit

Gate

circuits

which

can

allow

the

pawl

magnets

to

energize.

When

the

brush

senses

the

correct

voltage,

the

pawl

magnets

de

-energize

and

lock

the

print

wheels

at

the

proper

position.

Then

the

character

is

printed

as

the

clutch

assembly

finishes

its

one

revolution,

disengages,

and

opens

the

shutter.

The

photo

conductor

is

energized

and

the

system

is

ready

for

the

command.

the

supplied

is

for

the

decimal

8.

According

to

table

"0"

will

be

supplied

to

the

G,

B,

A

binaries.

The

D

binary

will

have

"l"

information

supplied.

The

"0"

or

"l'"

do

not

change

the

state

of

the

binaries.

The

-

and+transfer

pulses

cause

the

binaries

to

change

state

if

the

are

At

Since

the

will

change

The

is

equal

to

the

Thus

and

The

GR102.

Since

the

"Olt

is

(at

volts)

more

positive

than

the

diode

GRl02

is

The

The

ANALOG

CIRCUITRY

OPERATION.

Sincethe

column

boardscontain

stored

binary

information,

an

analog

function

can

be

derived

to

drive

a

strip

chart

recorder.

The

analog

circuitry

provides

the

following:

a.

A

graphic

presentation

whereby

the

trend

of

recorded

data

can

be

seen

at

a

glance.

b.

Three

digits

of

analog

information

where

full

scale

on

the

recorder

may

beafew

parts

per

million

of

the

original

printed

reading.

c.

A

recording

where

an

increasing

numerical

count

is

always

an

upward

direction

on

the

strip

chart

recording.

d.

An

analog

recording

which

is

always

on

scale.

To

derive

the

analog

voltage

a

switching

arrrangement

is

used

which

utilIzes

the

stored

binary

data

from

three

consecutive

columns

of

the

printed

data.

Any

three

of

the

first

nine

columns

may

be

used

as

well

as

the

first

two

right

hand

digits.

The

binary

output

data

is

weighted

according

to

the

code

required

by

the

storage

units.

Four

resistors

are

used

to

develop

a

staircase

function

from

the

four

storage

binaries.

The

four

weighting

resistors

are

in

the

ratio

4221.

Refer

to

the

analog

circuitry

schematic.

Each

of

the

three

storage

decades

then

produces

a

staircase

function

withalevel

proportional

to

the

numerical

value

of

its

stored

binary

data.

The

three

staircase

voltages

are

then

mixed

in

proportion

to

their

decade

value

or

in

the

ratio

of

1,

10,

100,

to

produce

a

single

staircase

function

1000

part

in

amplitude.

Each

discrete

step

then

represents.

10/0

of

full

scale

and

for

practical

purposes

is

an

analog

function.

This

output

voltage

is

then

attenuated

and

applied

directly

toapotentiometer

The

analog

signal

is

also

applied

to

an

can

be
