USING THE STATUS LED TO TROUBLESHOOT SYSTEM PROBLEMS
The Power Wave / Power Feed are best diagnosed 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 condition 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 trou- bleshooting charts for both machine and weld perfor- mance.
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 355/405 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.
