SECTION 1 SAFETY PRECAUTIONS

10 Safety Precautions 11 Safety - English

WARNING These Safety Precautions arefor your protection They summarize pre-

cautionary information from the referenceslisted in Additional Safety Information sec-

tion Before performing any installation or operatingprocedures be sure to read and follow the safety precau-tions listed below as well as all other manuals materialsafety data sheets labels etc Failure to observe SafetyPrecautions can result in injury or death

PROTECT YOURSELF AND OTHERS --Some welding cutting and gougingprocesses are noisy and require ear

protection The arc like the sun emitsultraviolet (UV) and other radiationand can injure skin and eyes Hot metal can causeburns Training in the proper use of the processesand equipment is essential to prevent accidentsTherefore

1 Always wear safety glasses with side shields in anywork area even if welding helmets face shields andgoggles are also required

2 Use a face shield fitted with the correct filter andcover plates to protect your eyes face neck and

ears from sparks and rays of the arc when operatingor observing operations Warn bystanders not towatch the arc and not to expose themselves to therays of the electric-arc or hot metal

3 Wear flameproof gauntlet type gloves heavy long-sleeve shirt cuffless trousers high-topped shoesand a welding helmet or cap for hair protection toprotect against arc rays and hot sparks or hot metalA flameproof apron may also be desirable as protec-tion against radiated heat and sparks

4 Hot sparks or metal can lodge in rolled up sleevestrouser cuffs or pockets Sleeves and collars shouldbe kept buttoned and open pockets eliminated fromthe front of clothing

5 Protect other personnel from arc rays and hotsparks with a suitable non-flammable partition orcurtains

6 Use goggles over safety glasses when chipping slagor grinding Chipped slag may be hot and can fly farBystanders should also wear goggles over safetyglasses

FIRES AND EXPLOSIONS -- Heat fromflames and arcs can start fires Hotslag or sparks can also cause fires andexplosions Therefore

1 Remove all combustible materials well away fromthe work area or cover the materials with a protec-tive non-flammable covering Combustible materialsinclude wood cloth sawdust liquid and gas fuelssolvents paints and coatings paper etc

2 Hot sparks or hot metal can fall through cracks orcrevices in floors or wall openings and cause a hid-den smoldering fire or fires on the floor below Make

certain that such openings are protected from hotsparks and metalldquo3 Do not weld cut or perform other hot work until the

workpiece has been completely cleaned so that thereare no substances on the workpiece which mightproduce flammable or toxic vapors Do not do hotwork on closed containers They may explode

4 Have fire extinguishing equipment handy for instantuse such as a garden hose water pail sand bucketor portable fire extinguisher Be sure you are trainedin its use

5 Do not use equipment beyond its ratings For ex-

ample overloaded welding cable can overheat andcreate a fire hazard

6 After completing operations inspect the work areato make certain there are no hot sparks or hot metalwhich could cause a later fire Use fire watchers whennecessary

7 For additional information refer to NFPA Standard51B Fire Prevention in Use of Cutting and WeldingProcesses available from the National Fire Protec-tion Association Batterymarch Park Quincy MA02269

ELECTRICAL SHOCK -- Contact withlive electrical parts and ground cancause severe injury or death DO NOTuse AC welding current in damp areasif movement is confined or if there isdanger of falling



6


1 Be sure the power source frame (chassis) is con-nected to the ground system of the input power

2 Connect the workpiece to a good electricalground

3 Connect the work cable to the workpiece A pooror missing connection can expose you or othersto a fatal shock

4 Use well-maintained equipment Replace worn ordamaged cables

5 Keep everything dry including clothing work

area cables torchelectrode holder and powersource

6 Make sure that all parts of your body are insulatedfrom work and from ground

7 Do not stand directly on metal or the earth whileworking in tight quarters or a damp area standon dry boards or an insulating platform and wearrubber-soled shoes

8 Put on dry hole-free gloves before turning on thepower

9 Turn off the power before removing your gloves

10 Refer to ANSIASC Standard Z491 (listed onnext page) for specific grounding recommenda-tions Do not mistake the work lead for a groundcable

ELECTRIC AND MAGNETIC FIELDSmdash May be dangerous Electric cur-rent flowing through any conduc-tor causes localized Electric andMagnetic Fields (EMF) Welding and

cutting current creates EMF around welding cablesand welding machines Therefore

1 Welders having pacemakers should consult theirphysician before welding EMF may interfere withsome pacemakers

2 Exposure to EMF may have other health effects whichare unknown

3 Welders should use the following procedures tominimize exposure to EMF

A Route the electrode and work cables togetherSecure them with tape when possible

B Never coil the torch or work cable around yourbody

C Do not place your body between the torch andwork cables Route cables on the same side ofyour body

D Connect the work cable to the workpiece as closeas possible to the area being welded

E Keep welding power source and cables as faraway from your body as possible

FUMES AND GASES -- Fumes andgases can cause discomfort or harmparticularly in confined spaces Donot breathe fumes and gases Shield-ing gases can cause asphyxiation

Therefore

1 Always provide adequate ventilation in the work areaby natural or mechanical means Do not weld cut orgouge on materials such as galvanized steel stain-less steel copper zinc lead beryllium or cadmiumunless positive mechanical ventilation is providedDo not breathe fumes from these materials

2 Do not operate near degreasing and spraying opera-tions The heat or arc rays can react with chlorinatedhydrocarbon vapors to form phosgene a highlytoxic gas and other irritant gases

3 If you develop momentary eye nose or throat ir-ritation while operating this is an indication thatventilation is not adequate Stop work and takenecessary steps to improve ventilation in the workarea Do not continue to operate if physical discom-fort persists

4 Refer to ANSIASC Standard Z491 (see listing below)for specific ventilation recommendations

SECTION 4 OPERATION

43 Modes of Operation

The EPP-360 operates in the Cutting Mode through a single continuously adjustable output current range from

30 amps through 360 amps using either the Current Potentiometer on the front panel or a remote current refer-ence signal fed into connector J1

When using a remote signal 1 volt corresponds to 36 amps and 360 amps corresponds to a signal of 1000VDC

The EPP-360 defaults to the Cutting Mode of operation unless the command signal from a remote control forMarking Mode is supplied

The power source is placed in Marking Mode with an external isolated relay or switch contact connecting J1-R(115VAC) to J1-C See Schematic Diagram included inside back cover This contact closure must be made before(50 mS or longer) issuing a Start or Contactor On command

In the CNC Marking mode the output current is adjusted through a single continuously adjustable range from0 amps through 36 amps using the remote current reference signal fed into connector J1 In the Panel Markingmode the output current can be adjusted from 0 - 18 amps using the panel potentiometer as the unit is shippedIf SW1-1 (which is open on the control board) is closed the range becomes 0 -18 amps max

When using a remote signal 1 volt corresponds to 36 amps and 36A corresponds to a signal of 1000 VDC

431 Single Power Source (used with the CNC two basic modes of operation are possible)

1 Panel Mode - (switch is provided on the power source) Put PanelRemote switch to Panel position Used with

a limited capability CNC that can only provide a startstop signal to the power source The microcontroller inthe power source will accept the analog setting from the panel potentiometer as the cut current informationBased on this value it will calculate the initial current value the pilot arc and the upslope time The cut valueand PA value can be displayed prior to cutting by moving the spring return switch on the power source tothe cut current preset and the pilot arc preset positions If the pilot arc current is deemed insufficient theCNC can increase it by providing inputs on the PA0 and PA1 control leads The increased values are as fol-lows

SECTION 4 OPERATION

1 Parallel Mode of operation - Connect power sources together as shown in section 36 Set the panelremoteswitches on both power sources to remote If the units will be used for cutting and both power sources are to

contribute to the cut current value activate the logic input labeled ldquoHI CURRENTrdquo (pin ldquoTrdquo) on the CNC cable Inthis manner a maximum current of 720 amps can be provided for an analog input of 10 VDC from the CNC If theldquoHI CURRENTrdquo input is deactivated the supplemental power source will not provide any output even though it isconnected to the primary power source In marking mode only the primary power source will supply the mark-ing current If alternating marking and cutting operations are done the ldquoHI CURRENTrdquo input can be maintainedand the mark input will control whether both or only one power source will provide output current The markingcurrent range is from 10 to 36 amps and the cut current range is from 30 to 720 amps

44 Sequence of Operation

432 Multiple Power Sources

A Apply power by closing the line (wall) switch The EPP-360 does not contain its own power OnOff switchOnce power is supplied the EPP-360 display board will display ldquoEPP-360rdquo briefly followed by the display ldquoPrxxxrdquo indicating the software program revision number then ldquo0 ampsrdquo and ldquo0 voltsrdquo

B Select Panel Remote setting for current control depending on whether your CNC has remote current con-trol capability

1 If using the ldquoPanelrdquo mode the selected cutting current may be viewed by holding the front panel switchin the ldquoCut Current Presetrdquo position In the ldquoPanelrdquo mode the Pilot Arc Current Initial Current and Up-slope Time are determined by the power source based on the selected cutting current The selectedPilot Arc Current can be viewed by holding the front panel switch in the ldquoPA Current Presetrdquo position Seesection 42 Control Panel

2 If using the ldquoRemoterdquo mode there are two possible modes of operation

a The default mode is similar to the ldquoPanelrdquo mode with the exception that the cutting current com-mand is supplied by the CNC instead of the front panel potentiometer Scaling of the remote cur-rent command is 10 V DC = 36 amps This mode is useful if the CNC does not have the capabilityof controlling the initial current and sloping of the output For remote control connections see theCNC interface diagram

b If your CNC has the capability of controlling Initial Current and Slopes place the PanelRemote switchin ldquoRemoterdquo and supply a contact closure between pins ldquoRrdquo and ldquoVrdquo of the CNC interface connectorIn this mode the CNC must supply the analog signal to control Initial Current Upslope and Cut Cur-rent level Scaling is the same as default mode Pilot Arc current will be controlled by a second 0 ndash 10V DC analog signal if available or by supplying a binary coded signal as defined in the CNC interfacediagram Scaling of the pilot arc signal is 10 V DC = 45 amps

C Begin plasma cutting operation This may require setting of other variables such as gas pressures flow ratesand torch height etc

D If for any reason cutting or marking fails to initiate the EPP-360 should display an error code indicating thereason for the shutdown See ldquoHelp Codesrdquo in the troubleshooting section

a loose or missing display cable between the main control board and the display board b lack of +15 volt bias supply which could be caused by blown fuses F1 or F2 c an open circuit breaker (CB1) on the front panelIf the unit shows Error 5 after the program number display times out look for a closed start switch To reset theunit simply open the start switch At this point the display should show 0rsquos in both windows If the power sourceis not connected to a CNC at power up the emergency stop relay (K4) in the power source is not energized pre-venting any relay operation in the power source itself

If the CNC has been booted up the display should read 0 for both the volts and amps The unit will not respondto a start signal until itrsquos master select input (pin H on J1) is connected to the ldquoHOTldquo side of 115 input (masterselect input) This connection is handled in the CNC to primary supply cable Note all inputs from the CNC arerelay closures providing 115 V AC inputs to the isolation board (PCB4 in the power source) The isolation board

converts these inputs to open collector type outputs The control will monitor various signals in the idle modeand will shut down with an error indication if the condition is not satisfactory Errors 1 3 4 5 9 or 12 (See 63Help code list)As the start switch is activated and the unit is being prepared for cutting additional conditions are being moni-tored The resulting error conditions are as follows Error 2 6 8 12 13 14 15 17 18 19 or 113 (See 63 Help codelist)

63 Help Code list

Error number displays and their meaning for the EPP-360 power supply

Error 1 +- 15 deviation in the idle mode is exceeded

Error 2 Line voltage during cut drops by more than 20

Error 3 Problem with the bias supplies on the control board The +15 and -15 volt supplies are not balanced boardshould be replaced

Error 4 Thermal switch has opened Unit is disabled until overheated component cools down Look for fans notworking or restrictions on input or output louvers

Error 5 The start switch from the CNC was already on when the power source was powered up Unit will not befunctional until start signal is removed and then reapplied

Error 6 Ignition did not take place during the 10 seconds allowed for arc ignitionNote This should rarely occur since the CNC has a much shorter time allowed for the ignition time andwill reset the power source to idle

Error 7 Not used

Error 8 Electrode current was present before the PWM was enabled Most likely caused by an electrode to nozzle

short on the torchError 9 Open circuit voltage in idle mode was over 40 volts Possible cause leaky IGBTs faulty PWM drive

Error 10 Open circuit voltage is over 70 volts when unit is powered up Possible cause leaky IGBTrsquos faulty PWM

Error 11 Not used

Error 12 Shut down due to single phasing Fuse blown in supply line circuit

Error 13 Open circuit voltage did not reach 300 volts in the allowed time Check PWM circuit amp E-Stop on J1

Error 14 Ambient temperature exceeded 55 C in control enclosure

Error 15 Bus voltage did not reach 100 volts during the allowed time Bus charge relay or surge limiting resistorsdefective
