Fault codes for the MA4, MA6 and U6 panels
Fault codes are updated every three seconds. They are shown on the display in the form of
a symbol, as follows:
The upper figure in the symbol is the number of the particular fault code. The
lower figure indicates where the fault is:
0 = control panel 1 = cooling unit 2 = power source
3 = wire feed unit 4 = remote control unit
The above symbol show that the control panel (0) has lost contact with the power source.
Symbols may be steady or flashing, depending on the type of fault. Flashing symbols are
indicaded with “o” in the table below.
If several faults have been detected, the code of only the most recent fault is displayed.
Press any of the function keys in order to clear the symbol from the display.
