3.4 - Error codes and alarm signals.

3.4.1 - 02 - EEPROM error.

Block due to software error. Replace the control board (29).

3.4.2 - 10 - Malfunction in the circuit to detect short-circuits at the output.

Upon power source start-up this test checks the operating conditions by performing a brief
test to generate the open-circuit output voltage. While this is taking place it is important that the
torch not touch the workpiece or welding bench.
The following conditions may be detected during this test:
− Output voltage present and output current present = error 54;
− Output voltage present and output current absent = correct operation;
− Output voltage absent and output current present = error 54;
− Output voltage absent and output current absent = error 10.
Error 10 indicates that a low output voltage (<45 Vdc) has been detected, with no output
current from the power source. This test is carried out only during the power source start-up.
This may be caused by an interruption in the inverter command circuits, or in the power
circuits, or in the output voltage detection line.
Check the wiring between power source +(H) output terminal and terminal J7 of power board
(32) and wiring between terminals 9(+) and 10(-) of J1 control board (29) and terminals 9(+) and
10(-) of J1 power board (32).
In case of "Error 10" carry out the open circuit operation test in par. 3.3.7.
If results are positive, replace control board (29).

3.4.3 - 42 - Wire feeder motor (31) fault.

This signal indicates a failure in the wire feeder motor (31) supply circuit.
In particular, motor supply voltage is generated but no motor current absorption is detected
(open circuit).
See WIRE FEEDER MOTOR (31) TEST, par. 3.3.6.

3.4.4 - 52 - "trG" on display (M). Start button pressed during start-up.

See START COMMAND TEST, par. 3.3.4.
3.4.5 - 53 - "trG" on display (M). Start button pressed while resetting from stop due to
temperature beyond allowable limits.
The high temperature alarm stops the power source with indication "tH0" on display (M), but
it doesn't remain in memory. It is automatically reset when the temperature falls within the
allowed limits.
It may occur that the unit resets when the start command is present; therefore, to prevent the
power source from starting suddenly, due to a random reset, this situation is detected and causes
a stored block in the power source, with "trG" indication on display (M).
To restore proper functioning, remove the start command, and if necessary carry out the
START COMMAND TEST, par. 3.3.4.
