USING THE STATUS LED TO
TROUBLESHOOT SYSTEM PROBLEMS
The Power Wave / Power Feed are best diagnosed as
a system. Each component (power source, user inter-
face, and feedhead) has a status light, and when a
problem occurs it is important to note the condition of
each. In addition, errors displayed on the user inter-
face in most cases indicate only that a problem exists
in the power source, not what the problem may be.
Therefore, prior to cycling power to the system,
check the power source status light for error
sequences as noted below. This is especially
important if the user interface displays "Err 006"
or "Err 100" .
Included in this section is information about the power
source Status LED, and some basic troubleshooting
charts for both machine and weld performance.
The STATUS LIGHT is a two color light that indicates
system errors. Normal operation is a steady green
light. Error conditions are indicated in the following
chart.
NOTE: The POWER WAVE 405 status light will flash
green, and sometimes red and green, for up to one
minute when the machine is first turned on. This is a
normal situation as the machine goes through a self
test at power up.
LIGHT CONDITION
Status LED is solid green (no blinking).
Status LED is blinking green.
Status LED is blinking red and green.
Status LED is solid red (no blinking).
Status LED is blinking red.
MEANING
1. System OK. Power source communicating normally
with wire feeder and its components.
2. Occurs during a reset, and indicates the POWER
WAVE 405 is mapping (identifying) each component
in the system. Normal for first 1-10 seconds after
power is turned on, or if the system configuration is
changed during operation.
3. Non-recoverable system fault. If the PS Status light
is flashing any combination of red and green, errors
are present in the POWER WAVE 405. Read the
error code before the machine is turned off.
Error Code interpretation through the Status light is
detailed in the Service Manual. Individual code digits
are flashed in red with a long pause between digits. If
more than one code is present, the codes will be
separated by a green light.
To clear the error, turn power source off, and back
on to reset.
Non recoverable hardware fault. Generally indicates
nothing is connected to the POWER WAVE 405 wire
feeder receptacle. See Trouble Shooting Section.
