GENERAL

INFORMATION

This

manual

provides

knowledge

required

to

repair

trouble

which

may

occur.

with

ACS-152.

Section

covers

the

principle

of

operation.

concerns

the

of

the

major

components

for

reference.

Note:

High

used

in

device.

SECTION

2

PRINCIPLE

OF

OPERATION

Normal

operation

Capacitor

C6

is

charged

through

C5

to

operate

RLI

in

the

initial

phase.

When

the

tubing

is

inserted

between

seal

electrodes,

uSl

operates

to

drive

RL1.

At

that

time,

RL2

is

also

operated

by

the

contact

of

RL1,

and

SO(plunger)

pinches

the

tube.

With

RLI

operated,

the

vacuum

tube

operates

to

oscillated

at

40.7

MH

|

The

oscillation

output

dielectrical-ly

heats

the

tubing

to

fuse

it.

When

it

is

fused,

an

electrode

gap

is

shortened.

Then

uS2

operates

to

stop

operation

of

RLl.

When

operation

of

RL1

ends,

.oscillation

stops

and

the

fused

tubing

is

cooled.

Tubing

cool-

ing

time

is

set

by

discharge

of

C7

which

is

connected

to

RL2.

During

this

cooling

time,

SO

(plunger)

which

is

connected

to

RL2

pinches

the

tube.

Operation

under

abnormal

conditions

When

the

tubing

is

wet

by

blood

or

liquids,

high

frequency

short

circuits

between

the

electrodes,

thus

dielectric

heating

of

the

tube

is

not

performed.

If

the

tubing

is

left

under

that

condition,

the

vacuum

tube

can

become

defective.

To

prevent

this,

RL1

operates

only

for

discharge

time

(approx.

4

seconds),

then

oscillation

is

automatically

stopped

,

and

the..plunger

is

returned

to

its

original

position.
