Error codes.

3.4.1

-02- EEprom error.

Block due to user data memory writing error.
Replace panel board (48).
3.4.2 -06- Communication error detected by panel
board (48).
3.4.3 -09- Communication error detected by INV
board on power board (45).
Communication error between panel board (48) and INV
board on power board (45).
Check the wiring between J1 on panel board (48) and J7
on power board (45).
Check correct fixing and connections cleaning of the INV
board on power board (45), J4 connector.
Replace panel (48) and/or power (45) boards.
3.4.4 -10- Missing voltage and current at the power
source output.
Upon power source start-up the control checks the
operating conditions by performing a brief test to generate
the open-circuit output voltage.
EN
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 at the power source start-up, or
with inverter running, the circuits for detecting the output
voltage and output current, on power board (45), detect
voltage = 0 and current = 0.
This situation is possible only with the inverter broken
(thus it does not generate the alternating voltage on the
primary circuit of the TF5 power transformer) or with one
or both voltage and current detection lines interrupted.
Perform the "open circuit operation" tests in par. 3.3.8 and
the "operation on resistive load" tests in par. 3.3.9.
3.4.5 -42- "Motor fault" on display A. Motor (25) en-
coder signal error.
The signal provided by the encoder built into the motor
(25) is used as a speed feedback signal to adjust the motor
speed.
28
"Error 42" indicates that the signal provided by the en-
coder is not suited to the reference signal generated by the
panel board (48) and thus the motor (25) speed is out of
control.
Perform the "wire feeder motor operation" tests in par.
3.3.7.
3.4.6 -53- "Release start button" on display A. Start
button pressed at start-up or while reset-
ting from stop due to overtemperature.
The high temperature and the wire feed unit guard open
alarms stop the power source, with a message on the con-
trol panel of the corresponding alarm.
These alarms automatically reset when the temperature is
again within the allowed limits or the guard is closed.
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 power source block, with the mes-
sage "Release start button" on display A.
To restore proper operation, remove the start command
(see par. 3.3.4).
3.4.7 -54- "Current not 0" on display A. Short-cir-
cuit between torch and workpiece upon
start-up.
Upon power source start-up the control 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 54 indicates a possible short-circuit or isolation leak
in the power circuit at the output of the secondary diodes
group on power board (45) and polarity reverser.
Check the wiring between VITE1 and VITE2 terminals, po-
larity reverser and power source C and D output terminals.
If defective connections are found, fix and replace any
damaged components.
3.4.8 -57- "Motor current high" on display A. Exces-
sive wire feeder motor (25) current.
The panel board (48) is equipped with a supply current
limiting circuit for motor (25), to protect it over any over-
