Two EPP-360’s, connected in parallel, and can be used for marking down to 10A and cutting from 30A up to
720A.
OPERATION OF TWO PARALLEL EPP-360’S:
1. Provide start/stop, Cut/Mark, “HI CURRENT” logic signals and either logic or analog inputs to control the pilot
current signals to primary unit for both cutting and marking. When marking, both power sources are powered up, but the mark signal disables the output of the supplemental power source.

SECTION 4 OPERATION
4.3 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 reference signal fed into connector J1.
When using a remote signal, 1 volt corresponds to 36 amps, and 360 amps corresponds to a signal of 10.00
VDC.
The EPP-360 defaults to the Cutting Mode of operation unless the command signal from a remote control for
Marking 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 from
0 amps through 36 amps using the remote current reference signal fed into connector J1. In the Panel Marking mode, the output current can be adjusted from 0 - 36 amps using the panel potentiometer, as the unit is
shipped. If 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 3.6 amps, and 36A corresponds to a signal of 10.00 VDC.
4.3.1. 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 Panel/Remote switch to Panel position. Used with
a limited capability CNC that can only provide a start/stop signal to the power source. The microcontroller in
the power source will accept the analog setting from the panel potentiometer as the cut current information.
Based on this value it will calculate the initial current value, the pilot arc and the upslope time. The cut value
and P.A. value can be displayed prior to cutting by moving the spring return switch on the power source to
the cut current preset, and the pilot arc preset positions. If the pilot arc current is deemed insucient, the
CNC can increase it by providing inputs on the PA0 and PA1 control leads. The increased values are as follows:
PA0 PA1
o o no change
on o value increased by 12.5%
o on value increased by 25%
on on value increased by 37.5%

SECTION 4 OPERATION
The table used to calculate the initial current, pilot current and upslope values are stored in the micro and contains the following information:
Cut Current
(amps)
30 20 15 200
50 25 20 250
100 50 25 500
200 100 30 800
300 150 35 900
360 180 40 950
Start Current
(amps)
Pilot Arc Current
Command (amps)
Upslope Time
(msec)
If values other than the table values are used for the cut current, the corresponding values are calculated assuming a linear slope for all the required parameters.
2. Remote Mode -
a. Partial CNC operation - (CNC cable pin “V” open, open for internal control) In this mode of operation the
panel/remote switch needs to be in the REMOTE position. The CNC should be providing the cut current reference and start/stop signal to the power source. Based on the cut reference the micro in the power source will
compute the initial current, pilot current and upslope time.
b. Remote with Full CNC Mode - (CNC cable pin “V” closed, closed for external control) Panel/remote switch
on the power source is set to REMOTE. The CNC should activate the input labeled “full CNC control” on pin
“V” of the interconnect cable. In this mode all parameters are controlled by the CNC, including start current,
pilot current and sloping times. The control of the pilot current can be done either by logic inputs or by an
analog input. If the analog input is less than 0.5 volts the power source will use the logic inputs PA0 and PA1
to provide the requested pilot arc current, based on the following combination:
PA0 PA1 Pilot current in amp
open open 10
closed open 20
open closed 30
closed closed 40
If the analog reference is used, 10 VDC will provide 45 amps or 1 V = 4.5 amps.
Marking - Can be done in both panel and remote mode and requires the mark mode select input to be closed
by the CNC. In the panel mode the maximum marking current (set by the panel potentiometer) is 36 amps.
If SW1-1 (which is open on the control board) is closed, the range becomes 0 -18 amps max. In the remote
mode the marking current is set by the main reference input and 10 VDC will provide 36 amps or 1 V = 3.6
amps of marking current.
24
SECTION 4 OPERATION
4.3.2 Multiple Power Sources
1. Parallel Mode of operation - Connect power sources together as shown in section 3.6. Set the panel/remote
switches 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 “HI CURRENT” (pin “T”) on the CNC cable. In
this manner a maximum current of 720 amps can be provided for an analog input of 10 VDC from the CNC. If the
“HI CURRENT” input is deactivated the supplemental power source will not provide any output even though it is
connected to the primary power source. In marking mode only the primary power source will supply the marking current. If alternating marking and cutting operations are done, the “HI CURRENT” input can be maintained
and the mark input will control whether both or only one power source will provide output current. The marking
current range is from 10 to 36 amps and the cut current range is from 30 to 720 amps.
4.4 Sequence of Operation
A. Apply power by closing the line (wall) switch. The EPP-360 does not contain its own power On/O switch.
Once power is supplied, the EPP-360 display board will display “EPP-360” briey, followed by the display “Pr
x.xx”, indicating the software program revision number, then “0 amps” and “0 volts”.
B. Select Panel / Remote setting for current control depending on whether your CNC has remote current con-
trol capability.
1. If using the “Panel” mode, the selected cutting current may be viewed by holding the front panel switch
in the “Cut Current Preset” position. In the “Panel” mode, the Pilot Arc Current, Initial Current, and Upslope Time are determined by the power source based on the selected cutting current. The selected
Pilot Arc Current can be viewed by holding the front panel switch in the “PA Current Preset” position. See
section 4.2 Control Panel.
2. If using the “Remote” mode, there are two possible modes of operation.
a. The default mode is similar to the “Panel” 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 current command is 1.0 V DC = 36 amps. This mode is useful if the CNC does not have the capability
of controlling the initial current and sloping of the output. For remote control connections see the
CNC interface diagram.
b. If your CNC has the capability of controlling Initial Current and Slopes, place the Panel/Remote switch
in “Remote” and supply a contact closure between pins “R” and “V” of the CNC interface connector.
In this mode the CNC must supply the analog signal to control Initial Current, Upslope, and Cut Current level. Scaling is the same as default mode. Pilot Arc current will be controlled by a second 0 – 10
V DC analog signal, if available, or by supplying a binary coded signal as dened in the CNC interface
diagram. 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, ow rates,
and torch height etc.
D. If for any reason cutting or marking fails to initiate, the EPP-360 should display an error code indicating the
reason for the shutdown. See “Help Codes” in the troubleshooting section.

6.0 Troubleshooting
6.1 Troubleshooting Introduction
Check the problem against the symptoms in the following troubleshooting guide. The remedy may be quite
simple. If the cause cannot be quickly located, shut o the input power, open up the unit, and perform a simple
visual inspection of all the components and wiring. Check for secure terminal connections, loose or burned wiring or components, bulged or leaking capacitors, or any other sign of damage or discoloration.
EQUIPMENT. ELECTRICAL WORK MUST BE PERFORMED BY AN EXPE
RIENCED ELECTRICIAN.
Stop work immediately if power source does not work properly.
Have only trained personnel investigate the cause.
Use only recommended replacement parts.
The cause of control malfunctions can be found by referring to the sequence of operations, electrical schematics
and checking the various components. A volt-ohmmeter will be necessary for some of these checks.
6.2 Troubleshooting Guide
As the unit is powered up, the display should show EPP-360 for one second and then show the program number
such as: Pr 3.01 or higher. If the display remains blank, look for the following:
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 panel.
If the unit shows Error 5 after the program number display times out, look for a closed start switch. To reset the
unit simply open the start switch. At this point the display should show 0’s in both windows. If the power source
is not connected to a CNC at power up, the emergency stop relay (K4) in the power source is not energized, preventing 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 respond
to a start signal until it’s master select input (pin H on J1) is connected to the “HOT“ side of 115 input (master
select input). This connection is handled in the CNC to primary supply cable. Note all inputs from the CNC are
relay 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 mode
and will shut down with an error indication if the condition is not satisfactory: Errors 1, 3, 4, 5, 9 or 12 (See 6.3
Help code list).
As the start switch is activated and the unit is being prepared for cutting, additional conditions are being monitored. The resulting error conditions are as follows: Error 2, 6, 8, 12, 13, 14, 15, 17, 18, 19 or 113 (See 6.3 Help code
list).
