WARNING

Mar ‘95

ELECTRIC AND

MAGNETIC FIELDS

may be dangerous

2.a. Electric current flowing through any conductor causes

localized Electric and Magnetic Fields (EMF). Welding

current creates EMF fields around welding cables and

welding machines

2.b. EMF fields may interfere with some pacemakers, and

welders having a pacemaker should consult their physician

before welding.

2.c. Exposure to EMF fields in welding may have other health

effects which are now not known.

2.d. All welders should use the following procedures in order to

minimize exposure to EMF fields from the welding circuit:

2.d.1.

Route the electrode and work cables together - Secure

them with tape when possible.

2.d.2. Never coil the electrode lead around your body.

2.d.3. Do not place your body between the electrode and

work cables. If the electrode cable is on your right

side, the work cable should also be on your right side.

2.d.4. Connect the work cable to the workpiece as close as

possible to the area being welded.

2.d.5. Do not work next to welding power source.

1.h. To avoid scalding, do not remove the

radiator pressure cap when the engine is

hot.

CALIFORNIA PROPOSITION 65 WARNINGS

SAFETY

ARC RAYS can burn.

4.a. Use a shield with the proper filter and cover

plates to protect your eyes from sparks and

the rays of the arc when welding or observing

open arc welding. Headshield and filter lens

should conform to ANSI Z87. I standards.

4.b. Use suitable clothing made from durable flame-resistant

material to protect your skin and that of your helpers from

the arc rays.

4.c. Protect other nearby personnel with suitable, non-flammable

screening and/or warn them not to watch the arc nor expose

themselves to the arc rays or to hot spatter or metal.

ELECTRIC SHOCK can

kill.

3.a. The electrode and work (or ground) circuits

are electrically “hot” when the welder is on.

Do not touch these “hot” parts with your bare

skin or wet clothing. Wear dry, hole-free

gloves to insulate hands.

3.b. Insulate yourself from work and ground using dry insulation.

Make certain the insulation is large enough to cover your full

area of physical contact with work and ground.

In addition to the normal safety precautions, if welding

must be performed under electrically hazardous

conditions (in damp locations or while wearing wet

clothing; on metal structures such as floors, gratings or

scaffolds; when in cramped positions such as sitting,

kneeling or lying, if there is a high risk of unavoidable or

accidental contact with the workpiece or ground) use

the following equipment:

• Semiautomatic DC Constant Voltage (Wire) Welder.

• DC Manual (Stick) Welder.

• AC Welder with Reduced Voltage Control.

3.c. In semiautomatic or automatic wire welding, the electrode,

electrode reel, welding head, nozzle or semiautomatic

welding gun are also electrically “hot”.

3.d. Always be sure the work cable makes a good electrical

connection with the metal being welded. The connection

should be as close as possible to the area being welded.

3.e. Ground the work or metal to be welded to a good electrical

(earth) ground.

3.f.

Maintain the electrode holder, work clamp, welding cable and

welding machine in good, safe operating condition. Replace

damaged insulation.

3.g. Never dip the electrode in water for cooling.

3.h. Never simultaneously touch electrically “hot” parts of

electrode holders connected to two welders because voltage

between the two can be the total of the open circuit voltage

of both welders.

3.i. When working above floor level, use a safety belt to protect

yourself from a fall should you get a shock.

3.j. Also see Items 6.c. and 8.

FUMES AND GASES

can be dangerous.

5.a. Welding may produce fumes and gases

hazardous to health. Avoid breathing these

fumes and gases.When welding, keep

your head out of the fume. Use enough

ventilation and/or exhaust at the arc to keep

fumes and gases away from the breathing zone. When

welding with electrodes which require special

ventilation such as stainless or hard facing (see

instructions on container or MSDS) or on lead or

cadmium plated steel and other metals or coatings

which produce highly toxic fumes, keep exposure as

low as possible and below Threshold Limit Values (TLV)

using local exhaust or mechanical ventilation. In

confined spaces or in some circumstances, outdoors, a

respirator may be required. Additional precautions are

also required when welding on galvanized steel.

5.b.

Do not weld in locations near chlorinated hydrocarbon

vapors

coming from degreasing, cleaning or spraying operations.

The heat and rays of the arc can react with solvent vapors

form phosgene, a highly toxic gas, and other irritating

products.

5.c. Shielding gases used for arc welding can displace air and

cause injury or death. Always use enough ventilation,

especially in confined areas, to insure breathing air is safe.

5.d. Read and understand the manufacturer’s instructions for this

equipment and the consumables to be used, including the

material safety data sheet (MSDS) and follow your

employer’s safety practices. MSDS forms are available from

your welding distributor or from the manufacturer.

5.e. Also see item 1.b. Mar ‘95

FOR ELECTRICALLY

powered equipment.

8.a. Turn off input power using the disconnect

switch at the fuse box before working on

the equipment.

8.b. Install equipment in accordance with the U.S. National

Electrical Code, all local codes and the manufacturer’s

recommendations.

8.c. Ground the equipment in accordance with the U.S. National

Electrical Code and the manufacturer’s recommendations.

CYLINDER may explode

if damaged.

7.a. Use only compressed gas cylinders

containing the correct shielding gas for the

process used and properly operating

regulators designed for the gas and

pressure used. All hoses, fittings, etc. should be suitable for

the application and maintained in good condition.

7.b. Always keep cylinders in an upright position securely

chained to an undercarriage or fixed support.

7.c. Cylinders should be located:

• Away from areas where they may be struck or subjected to

physical damage.

• A safe distance from arc welding or cutting operations and

any other source of heat, sparks, or flame.

7.d. Never allow the electrode, electrode holder or any other

electrically “hot” parts to touch a cylinder.

7.e. Keep your head and face away from the cylinder valve outlet

when opening the cylinder valve.

7.f. Valve protection caps should always be in place and hand

tight except when the cylinder is in use or connected for

use.

7.g. Read and follow the instructions on compressed gas

cylinders, associated equipment, and CGA publication P-l,

“Precautions for Safe Handling of Compressed Gases in

Cylinders,” available from the Compressed Gas Association

1235 Jefferson Davis Highway, Arlington, VA 22202.

SAFETY

iii

Mar ‘95

WELDING SPARKS can

cause fire or explosion.

6.a.

Remove fire hazards from the welding area.

If this is not possible, cover them to prevent

the welding sparks from starting a fire.

Remember that welding sparks and hot

materials from welding can easily go through small cracks

and openings to adjacent areas. Avoid welding near

hydraulic lines. Have a fire extinguisher readily available.

6.b. Where compressed gases are to be used at the job site,

special precautions should be used to prevent hazardous

situations. Refer to “Safety in Welding and Cutting” (ANSI

Standard Z49.1) and the operating information for the

equipment being used.

6.c. When not welding, make certain no part of the electrode

circuit is touching the work or ground. Accidental contact

can cause overheating and create a fire hazard.

6.d. Do not heat, cut or weld tanks, drums or containers until the

proper steps have been taken to insure that such procedures

will not cause flammable or toxic vapors from substances

inside. They can cause an explosion even

though

they have

been “cleaned”. For information, purchase “Recommended

Safe Practices for the

Preparation

for Welding and Cutting of

Containers and Piping That Have Held Hazardous

Substances”, AWS F4.1 from the American Welding Society

(see address above).

6.e. Vent hollow castings or containers before heating, cutting or

welding. They may explode.

6.f.

Sparks and spatter are thrown from the welding arc. Wear oil

free protective garments such as leather gloves, heavy shirt,

cuffless trousers, high shoes and a cap over your hair. Wear

ear plugs when welding out of position or in confined places.

Always wear safety glasses with side shields when in a

welding area.

6.g. Connect the work cable to the work as close to the welding

area as practical. Work cables connected to the building

framework or other locations away from the welding area

increase the possibility of the welding current passing

through lifting chains, crane cables or other alternate cir-

cuits. This can create fire hazards or overheat lifting chains

or cables until they fail.

6.h. Also see item 1.c.

SAFETY

PRÉCAUTIONS DE SÛRETÉ

Pour votre propre protection lire et observer toutes les instruc-

tions et les précautions de sûreté specifiques qui parraissent

dans ce manuel aussi bien que les précautions de sûreté

générales suivantes:

Sûreté Pour Soudage A L’Arc

1. Protegez-vous contre la secousse électrique:

a. Les circuits à l’électrode et à la piéce sont sous tension

quand la machine à souder est en marche. Eviter toujours

tout contact entre les parties sous tension et la peau nue

ou les vétements mouillés. Porter des gants secs et sans

trous pour isoler les mains.

b. Faire trés attention de bien s’isoler de la masse quand on

soude dans des endroits humides, ou sur un plancher

metallique ou des grilles metalliques, principalement dans

les positions assis ou couché pour lesquelles une

grande partie du corps peut être en contact avec la

masse.

c. Maintenir le porte-électrode, la pince de masse, le câble

de soudage et la machine à souder en bon et sûr état

defonctionnement.

d.Ne jamais plonger le porte-électrode dans l’eau pour le

refroidir.

e. Ne jamais toucher simultanément les parties sous tension

des porte-électrodes connectés à deux machines à soud-

er parce que la tension entre les deux pinces peut être le

total de la tension à vide des deux machines.

f. Si on utilise la machine à souder comme une source de

courant pour soudage semi-automatique, ces precautions

pour le porte-électrode s’applicuent aussi au pistolet de

soudage.

2. Dans le cas de travail au dessus du niveau du sol, se pro-

téger contre les chutes dans le cas ou on recoit un choc. Ne

jamais enrouler le câble-électrode autour de n’importe quelle

partie du corps.

3. Un coup d’arc peut être plus sévère qu’un coup de soliel,

donc:

a. Utiliser un bon masque avec un verre filtrant approprié

ainsi qu’un verre blanc afin de se protéger les yeux du

rayonnement de l’arc et des projections quand on soude

ou quand on regarde l’arc.

b. Porter des vêtements convenables afin de protéger la

peau de soudeur et des aides contre le rayonnement de

l‘arc.

c. Protéger l’autre personnel travaillant à proximité au

soudage à l’aide d’écrans appropriés et non-inflamma-

bles.

4. Des gouttes de laitier en fusion sont émises de l’arc de

soudage. Se protéger avec des vêtements de protection

libres de l’huile, tels que les gants en cuir, chemise épaisse,

pantalons sans revers, et chaussures montantes.

5. Toujours porter des lunettes de sécurité dans la zone de

soudage. Utiliser des lunettes avec écrans lateraux dans les

zones où l’on pique le laitier.

6. Eloigner les matériaux inflammables ou les recouvrir afin de

prévenir tout risque d’incendie dû aux étincelles.

7. Quand on ne soude pas, poser la pince à une endroit isolé de

la masse. Un court-circuit accidental peut provoquer un

échauffement et un risque d’incendie.

8. S’assurer que la masse est connectée le plus prés possible

de la zone de travail qu’il est pratique de le faire. Si on place

la masse sur la charpente de la construction ou d’autres

endroits éloignés de la zone de travail, on augmente le risque

de voir passer le courant de soudage par les chaines de lev-

age, câbles de grue, ou autres circuits. Cela peut provoquer

des risques d’incendie ou d’echauffement des chaines et des

câbles jusqu’à ce qu’ils se rompent.

9. Assurer une ventilation suffisante dans la zone de soudage.

Ceci est particuliérement important pour le soudage de tôles

galvanisées plombées, ou cadmiées ou tout autre métal qui

produit des fumeés toxiques.

10. Ne pas souder en présence de vapeurs de chlore provenant

d’opérations de dégraissage, nettoyage ou pistolage. La

chaleur ou les rayons de l’arc peuvent réagir avec les

vapeurs du solvant pour produire du phosgéne (gas forte-

ment toxique) ou autres produits irritants.

11. Pour obtenir de plus amples renseignements sur la sûreté,

voir le code “Code for safety in welding and cutting” CSA

Standard W 117.2-1974.

PRÉCAUTIONS DE SÛRETÉ POUR

LES MACHINES À SOUDER À

TRANSFORMATEUR ET À

REDRESSEUR

1. Relier à la terre le chassis du poste conformement au code

de l’électricité et aux recommendations du fabricant. Le dis-

positif de montage ou la piece à souder doit être branché à

une bonne mise à la terre.

2. Autant que possible, I’installation et l’entretien du poste

seront effectués par un électricien qualifié.

3. Avant de faires des travaux à l’interieur de poste, la

debrancher à l’interrupteur à la boite de fusibles.

4. Garder tous les couvercles et dispositifs de sûreté à leur

place.

SAFETY PRECAUTIONS

SELECT SUITABLE LOCATION

Place the welder where clean cooling air can freely

circulate in through the side louvers and out through

the rear louvers. Dirt, dust or any foreign material that

can be drawn into the welder should be kept at a

minimum. Failure to observe these precautions can

result in excessive operating temperatures and

nuisance shut-downs. Idealarc CV-400-I power

sources carry an IP23 enclosure rating. They are

rated for use in damp, dirty environments subject to

occasional falling water such as rain.

STACKING

The CV-400-I may be stacked three-high provided the

bottom machine is on a stable, hard, level surface. Be

sure that the two pins in the roof fit into the slots in the

base of the CV-400-I above it.

TILTING

Do not place the machine on a surface that is inclined

enough to create a risk of the machine falling over.

INPUT CONNECTIONS

Be sure the voltage, phase, and frequency of the input

power is as specified on the welder nameplate.

Gain access to the input reconnect panel by removing

the right case side of the CV-400-I (side nearest to the

Power switch.)

Have a qualified electrician connect the input leads to

L1, L2, and L3 of the input reconnect panel in accor-

dance with the National Electrical Code, all local

codes, and the connection diagram located on the

inside of the right case side. Use a three phase line.

The frame of the welder must be grounded. A ground

terminal marked with the symbol located on the

base of the machine is provided for this purpose. See

the National Electrical Code for details on proper

grounding methods.

Fuse the input circuit with the recommended super lag

fuses. Choose an input and grounding wire size

according to local codes or use the following table.

"Delay type"1circuit breakers may be used in place of

fuses. Using fuses or circuit breakers smaller than

recommended may result in "nuisance" tripping from

welder inrush currents even if not welding at high cur-

rents.

ELECTRIC SHOCK can kill.

•Only qualified personnel should

perform this installation.

• Turn the input power OFF at the discon-

nect switch or fuse box before working on

this equipment.

• Turn the Power switch on the CV-400-I

“OFF” before connecting or disconnect-

ing output cables, wire feeder or remote

connections, or other equipment.

• Do not touch electrically hot parts.

• Always connect the Idealarc CV-400-I

grounding terminal (located on the welder

base near the reconnect panel) to a good

electrical earth ground.

CONNECTION OF AUXILIARY EQUIPMENT

TO THE WIRE FEEDER RECEPTACLE

Occasionally, it may be necessary to make connection

to the circuits present in the 14-pin wire feeder recep-

tacle. These circuits, such as the auxiliary voltage,

contactor, and remote control circuits, may be

accessed with a K867 Universal Adapter. This

adapter plugs into the receptacle and provides the

user with short wire leads for connections. Refer to

the instructions provided with the K867, as well as the

wiring diagram for the CV-400-I power source, for

details on making those connections. For your conve-

nience, wire feeder connection details are shown in

the DIAGRAM section.

NOTE: If you intend to use a standard Lincoln wire

feeder, order the appropriate input cable for

the specific feeder. It will make all of the con-

trol and power connections between the CV-

400-I and the wire feeder WITHOUT the

need for a K867 Universal Adapter.

A., B., C. OUTPUT CONNECTORS

-Each connector is a Magnum Twist-Mate™,

receptacle. Insert a mating Twist-Mate™

plug, and twist clockwise to secure.

For GMAW processes, and most FCAW

processes, the positive output connection

goes to the wire feeder. One of the negative

output connections goes directly to the work.

A. POSITIVE OUTPUT CONNECTION.

B. LOW INDUCTANCE NEGATIVE CONNECTION.

-The low inductance connection is typically

used for short arc welding of mild steel, par-

ticularly on thin materials or when using CO2

shielding gas.

C. HIGH INDUCTANCE NEGATIVE OUTPUT CONNECTION.

-The high inductance connection is more suit-

able for short arc welding heavier weldments

or when using 75% Argon/25% CO2shield-

ing gas. This connection produces a softer

arc and a flatter bead with more wash-in than

the low inductance connection. A spray type

transfer is possible with either connection.

STARTING THE MACHINE

The power switch at the extreme right side of the con-

trol panel energizes the CV-400-I.

ADJUSTING THE OUTPUT VOLTAGE

USING THE DIGITAL METER

The digital meters in the CV-400-I incorporate a voltage pre-

set function. This allows the operator to set the desired

welding voltage before striking an arc. The digital meters

can also display welding current.

To make use of the voltage preset function, the Volts/Amps

switch must be in the "Volts" position. Turn the Voltage

Adjust knob until the digital meter displays the desired weld-

ing voltage. (See below if an external power source remote

control is installed.)

When an arc is struck, the digital meter displays the actual

welding voltage, as measured at the CV-400-I output termi-

nals.

NOTE: The arc voltage at the electrode may be as much as

two volts different from the CV-400-I output terminal

voltage. This is due to voltage drops present in the

welding cables, cable connections, and welding

gun. To minimize these drops, use cables of ade-

quate capacity, and make sure all connections are

clean and tight. Because of these voltage drops,

you may have to preset the CV-400-I for a slightly

higher welding voltage than your procedure calls for.

To read welding current, set the Volts/Amps switch to the

"Amps" position. The welding current will be displayed

whenever an arc is struck.

LOCAL/REMOTE SWITCH OPERATION

If voltage control is desired at the CV-400-I, the

Local/Remote switch must be in the "Local" position. The

Voltage Adjust on the front panel can be used to adjust the

CV-400-I output. (The remote control, even if connected,

will have no effect if the switch is in the "Local" position).

To use a remote control, such as the K857 (see INSTALLA-

TION section), place the Local/Remote switch (see Figure

B.1) in the "Remote" position. The remote control now con-

trols the output voltage, in the manner described above.

This control may be adjusted while welding to change the

CV-400-I output.

AUXILIARY POWER

42 volt AC auxiliary power, as required for some wire

feeders, is available through the wire feeder recepta-

cle. A 10 amp circuit breaker protects the 42 volt cir-

cuit from overloads.

CV-400-I Export machines only can also supply 115

volt AC auxiliary power through the wire feeder recep-

tacle. A 5 amp circuit breaker protects the 115 volt

circuit from overloads.

The CV-400-I can supply 220 volt AC power at 2

amps for powering water coolers or other equipment.

This auxiliary power is available from the Continental

European type receptacle mounted on the case back.

A 2 amp circuit breaker, located next to the recepta-

cle, protects this auxiliary from overloads.

NOTE: Do not use circuits 2 or 4 for control of auxil-

iary loads. (The 2-4 circuit is isolated from the

31-32 and 41-42 circuits.)

Note that some types of equipment, especially pumps

and large motors, have starting currents which are

significantly higher than their running current. These

higher starting currents may cause the circuit breaker

to open. If this situation occurs, the user should refrain

from using the CV-400-I auxiliary power for that equip-

ment.

___________________________________________

OVERLOAD PROTECTION

This welder has thermostatic protection from exces-

sive duty cycles, overloads, loss of cooling, and high

ambient temperatures. When the welder is subjected

to an overload or loss of cooling, a thermostat will

open. This condition will be indicated by the illumina-

tion of the yellow Thermostatic Protection Light on the

case front (see Figure B.1).The fan will continue to run

to cool the power source. No welding is possible until

the machine is allowed to cool and the Thermostatic

Protection Light goes out.

REMOTE VOLTAGE CONTROL (K857)

The K857 consists of a control box with 25 feet (7.6

m) of four conductor cable. Installation of a K857

Remote Voltage Control in the CV-400-I requires a

K864 Remote Control Adapter. Refer to the instruc-

tions provided with the K857 for hookup to the CV-

400-I. When properly connected, and with the CV-

400-I Local-Remote Switch in the "Remote" position,

the K857 functions the same as the CV-400-I Voltage

Adjust control, enabling minimum to maximum output

voltage adjustment of the CV-400-I.

SAFETY PRECAUTIONS

GENERAL MAINTENANCE

1. The fan motor has sealed bearings which require

no service.

2. In extremely dusty locations, dirt may clog the air

channels causing the welder to run hot with prema-

ture tripping of thermal protection. Blow out the

welder with low pressure air at regular intervals to

eliminate excessive dirt and dust build-up on inter-

nal parts.

MACHINE AND CIRCUIT PROTECTION

The CV-400-I Control PC Board has built-in diagnostic

routines to alert the operator when trouble exists.

When a trouble condition occurs, the CV-400-I meter

will display an error code, in the form "EXX", where

"XX" refers to a specific error. See TROU-

BLESHOOTING section for an explanation of the error

codes.

The power source is thermostatically protected

against overload or insufficient cooling. If the machine

is overloaded, the thermostat will open, thermal pro-

tection indicator light will turn on, and the output will

be zero. The fan will continue to run and auxiliary

power will still be available. The thermostat will

remain open until the machine cools, at which time it

will close and the output will again be available.

The CV-400-I is electronically protected against over-

loads and accidental short circuits. The overload pro-

tection circuit automatically reduces the output current

to a safe value when an overload is detected. If the

circuitry senses a short circuit, it will shut off the CV-

400-I output. The short circuit protection circuit can

be reset by turning the CV-400-I Power switch OFF

for at least 10 seconds. Remove the short before

turning the Power switch ON again.

CV-400-I

ELECTRIC SHOCK can kill.

•Only qualified personnel should

Procedure for Replacing PC Boards

Before replacing a PC board which is suspected of

being defective, visually inspect the PC board in ques-

tion for any electrical or mechanical damage to any of

its components and conductors on the back of the

board.

a. If there is no visible damage to the PC board,

install a new one and see if this remedies the prob-

lem. If the problem is remedied, reinstall the old

PC board to see if the problem still exists. If it

does no longer exist with old PC board:

1. Check the PC board harness connector pins for

corrosion, contamination, or looseness.

2. Check leads in the plug harness for loose or

intermittent connection.

b. If PC board is visibly damaged electrically, before

possibly subjecting the new PC board to the same

cause of failure, check for possible shorts, opens,

or grounds caused by:

1. Frayed or pinched lead insulation.

2. Poor lead termination, such as a poor contact

or a short to adjacent connection or surface.

3. Shorted or open motor leads, or other external

leads.

4. Foreign matter or interference behind the PC

boards.

c. If PC board is visibly damaged mechanically,

inspect for cause, then remedy before installing a

replacement PC board.

If there is damage to the PC board or if replacing

PC board corrects problem, return it to the local

Lincoln Electric Field Service Shop.

ELECTRIC SHOCK can kill.

• Have a qualified individual install and

service this equipment.

• Turn the power source input power off

at the disconnect switch before work-

ing on this equipment.

• Do not touch electrically hot parts.

WARNING

PC BOARD TROUBLESHOOTING

PROCEDURES

CONTROL PC BOARD

The Control PC Board controls all machine functions

including the thermal protection indicator light and the

Meter PC Board. Most problems, if not caused by

faulty wiring machine misuse, will stem from a faulty

Control PC Board.

Perform the following diagnostic procedure before

replacing the Control PC Board.

1. Turn off the input power at the fuse box.

2. Check for loose connections in the PC Board

plugs, particularly J3.

3. Disconnect the J3 plug from the Control PC Board.

Measure the resistance between the following wire

terminals in the plug:

A) Between wire #200 and wire #201.

B) Between wire #202 and wire #203.

Both of these resistances should be less than 1 ohm.

If these resistances are not less than 1 ohm, check the

wiring back to the main transformer.

If these voltages are less than 1 ohm, refer to

"Procedure for Replacing PC Boards."

METER PC BOARD

When the Meter PC Board malfunctions, first determine

if the rest of the machine functions correctly. If so, then

the problem is in either the harness between the meter

and control boards, or in the meter board itself. Refer

to "Procedure for Replacing PC Boards". As a last

resort, the Control PC Board may have to be replaced.

TROUBLESHOOTING

E-8

CV-400-I

If for any reason you do not understand the test procedures or are unable to perform the tests/repairs safely, contact your

Local Lincoln Authorized Field Service Facility for technical troubleshooting assistance before you proceed.

CAUTION

OUTPUT VOLTAGE

The open circuit voltage of the machine should be 10

to 43 volts. If any other condition exists, refer to the

Troubleshooting Guide.

FAULT PROTECTION OPERATION

The overload protection circuit on the PC Board will

cause the CV-400-I meter to display "E60". This pro-

tection circuit will reset itself automatically. The short

circuit protection circuit will cause the meter to display

"E00". The CV-400-I power switch must be turned

"OFF" and then "ON" to return the machine to normal

output.

CHECKING SNUBBER CIRCUIT

In case of an SCR malfunction or failure, the snubber

assembly should be checked. Disconnect the input

power to the CV-400-I at the fuse box and remove the

right side of the machine.

1.Visually inspect the snubber PC Board assembly

(located below the Control PC board on the case front

for overheated components or damaged compo-

nents).

OPTIONAL K857 REMOTE CONTROL

CHECK

Disconnect the remote output control and connect an ohm-

meter between pins C and B and rotate the rheostat in the

remote control. The resistance reading should go from zero

to 10K ohms. Repeat with ohmmeter across A and B with

the same results. Connect ohmmeter across A and C. The

reading should be 10K ohms. A lower reading will indicate a

shorted or partially shorted rheostat. A very high reading

will indicate an open rheostat. In either of the last two

cases, replace the rheostat.
