SERVICE AND TROUBLESHOOTING
Fig. 40 LED indicators
Meaning of the LEDs:
Row A (red)
These indicators are normally off.
LED lit up red: Control fuse defective.
The six control fuses are located on the interface PCB in the machine and are accessible after flipping open the cover.
They are arranged in a row and have the same enumeration as the LEDs. The LEDs in position 7 and 8 have no function.
A tripped control fuse normally indicates a defective switching power supply unit. An output-side overload of the
switching power supply unit is usually not present when a fuse is tripped, as all power supply units used are short-
circuit-proof and are also regulated automatically, even in the case of an overload.
Row B (green)
These indicators are normally on (except LED B2).
They indicate the status of the output voltages of the internal power supply units.
With a tripped fuse (row A), a LED of row B will not light up, because a power supply unit which is disconnected from the
mains by a fuse is no longer supplying output voltage.
If a green LED (except for B2) is off and no red LEDs are lit up, the power supply unit in question is overloaded on the
output side or is defective.
•
B1: Weld head power supply unit. The power supply unit provides power to the buttons in the handle of the weld
head, the limit switch (home position) and the head encoding with control voltage. If the voltage is missing, the
machine cannot be started. Usually, the "No weld head connected" error message appears, as head encoding does
not have a function.
•
B2: Power supply unit of internal printer. This LED can also be off without there being an error. The power supply
unit is only switched on during printing.
–
Printer power supply unit control: Carry out printing with the internal printer.
– or –
From the main menu, select "System settings" > "Service" > "Switch on internal printer".
–
In both cases, the power supply unit is activated and the B2 LED lights up.
