APARTADO 4 FUNCIONAMIENTO
1. Aplique energía cerrando el conmutador de línea (de pared).
(El EPP-450 no tiene un conmutador de conexión/desco-
nexión). La luz de alimentación principal se iluminará y la luz
de fallo parpadeará y después se apagará.
2. El botón de E-parada está fuera.
3. Seleccione la conguración de panel/remoto.
4. Establezca el conmutador alto/bajo de arco piloto. Si se
selecciona alto/bajo de arco piloto desde un control remoto,
el conmutador debe estar en la posición bajo. (Consulte los
datos de corte del manual del soplete).
5. Si utiliza el modo panel, visualice los amperios precongu-
rados con el conmutador AMPERIOS ACTUALES/PRECONFI-
GURACIÓN. Ajuste la corriente hasta que el valor deseado
aproximado se muestre en el amperímetro. Si utiliza el modo
remoto, al colocar el conmutador amperios actual/amperios
preconguración en la posición amperios preconguración
proporciona la corriente de salida inicial enviada por el
control remoto.
6. Comience la operación de corte de plasma. Esto puede incluir
la conguración manual de otras opciones, dependiendo
del paquete de plasma total.
7. Si utiliza el modo panel, después de que el corte haya
comenzado, ajuste la corriente a la cantidad deseada.
8. Si el corte o el marcado no se inicia, consulte la luz de fallo. Si
se ilumina la luz de fallo, consulte la sección de localización
y resolución de problemas.
Nota:
La luz de fallo parpadea cuando el conector se
activa por primera vez, lo cual indica que el bus DC
recibe la alimentación necesaria para funcionar con
normalidad.

4.3 Sequence of Operation
1. Apply power by closing the line (wall) switch.
(The ESP-400C does not have an on/off
switch). The main power light will illuminate
and the fault light will flash and then go out.
2. Select the Panel/Remote setting.
3. Set pilot arc High/Low switch. (Refer to cutting
data in the torch manual.)
4. If using panel mode, view preset amps with the
ACTUAL/PRESET AMPS switch. Adjust current
until the approximate desired value is shown on
the ammeter.
5. Begin plasma cutting operation. This may
include manually setting up other options,
depending on the total plasma package.
6. If using panel mode, after cutting has begun,
adjust current to desired amount.
7. Check for fault light. If a fault light illuminates,
refer to troubleshooting section.

4.4 Arc Initiation Settings
The time to achieve full current can be adjusted to
suit your particular system. This feature uses 50%
of the cutting current to start, dwell and then
gradually (less than a second) achieve full current.
The ESP-400C is factory shipped with this feature
enabled. The default settings are:
Minimum Start Current 40A
Start Current 50% of cut current
Timing to achieve full current 800 msec
Dwell Time 50 msec
