CONTROL BOX
(USER INTERFACE)
The system Control Box is the main entry
point for all system parameters, and from it
the user can control both power source and
wire feeder functions. Refer to Figure E.10.
The user interface motherboard is the heart
of the Control Box. Dependent upon the
option panels and the information received
through the network cable, it directs the
entire system as to the options, wire feed
speed, and weld cycle requirements and
parameters.
The options are divided into two physical
size categories. The smaller option, typical-
ly installed in the middle section of the con-
trol box, is dedicated to dual procedure,
head selection, and memory related func-
tions. The larger, or bottom section, is
reserved for control of the setup functions
for the power source (Power Wave 455)
and wire drive (Power Feeder 10) such as
mode, arc control, run in and timer set up.

In addition to the large and smaller size
options, there is a Display Panel which is
standard on the Control Box unit. The
Display Panel, typically installed in the
upper position of the Control Box assembly,
houses the encoder controls and the STA-
TUS LED. The controls are used to adjust
the wire feed speed, current, voltage and
trim parameters. The STATUS LED is
designed to blink a red and green code if a
fault should occur.
The internal Network Connector is used
when the Control Box is mounted on either
the power source or the wire drive units.
See System Diagram A and System
Diagram B in this section.
The optional Network Input and Output
receptacles are utilized when the Control
Box assembly is mounted independently
from both the wire drive and power source.
See System Diagram C in this section.
There are two DIP switch banks located on
the motherboard. They are labeled S1 and
S2 and are used to set display, trigger,
acceleration and run in functions.
