USING THE STATUS LED TO TROUBLESHOOT SYSTEM PROBLEMS

The POWER WAVE® / Power Feed are best diag- nosed as a system. Each component (power source, user interface, and feed head) has a status light, and when a problem occurs it is important to note the con- dition of each. In addition, errors displayed on the user interface 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 sys- tem, 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® 405M 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

MEANING

 

 

Status LED is solid green (no blinking).

1. System OK. Power source communicating normally

 

 

 

with wire feeder and its components.

 

 

 

 

 

 

Status LED is blinking green.

2. Occurs during a reset, and indicates the POWER

 

 

 

WAVE® 405M is mapping (identifying) each compo-

 

 

 

nent in the system. Normal for first 1-10 seconds

 

 

 

after power is turned on, or if the system configura-

 

 

 

tion is changed during operation.

 

 

 

 

 

 

Status LED is blinking red and green.

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® 405M. 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.

 

 

 

 

 

 

Status LED is solid red (no blinking).

Non recoverable hardware fault. Generally indicates

 

 

 

nothing is connected to the POWER WAVE® 405M

 

 

 

wire feeder receptacle. See Trouble Shooting Section.

 

Status LED is blinking red.

Not applicable.
