Error messages

6.2 Error messages
Depending on the options of the machine display, a fault is shown as follows:
Display type - machine control
Graphic display
two 7-segment displays
one 7-segment display
The possible cause of the fault is signalled by a corresponding fault number (see table). In the case of an
error, the power unit shuts down.
The display of possible error numbers depends on the machine version (interfaces/functions).
•
If multiple errors occur, these are displayed in succession.
•
Document machine errors and inform service staff as necessary.

Remedy
Check wire guide / hose package.
Switch off cold wire mode in the machine configuration
menu (off status). Connect the wire feeder.
Allow the machine to cool down.
Check the external shutdown devices. Check the jum-
per JP 1 on PCB T320/1.
Switch off the machine and check the mains voltage.
Check coolant level and top up if necessary.
Check the gas supply.
Switch the machine off and on. If the error persists,
notify the service department.
Slope "Acknowledge error" signal (0 to 1) using the
robot interface (if present).
Switch the machine off and on. If the error persists,
notify the service department.
Check welding torch.
Check the wire feed system (drives, hose packages,
welding torches, process wire feed speed and robot
travel speed) and correct if necessary.
Check plasma gas supply (leak tightness, kinks, guide,
connections, closure).
Check plasma gas supply (leak tightness, kinks, guide,
connections, closure).
Check cooling circuit (coolant level, leak tightness,
kinks, guide, connections, closure).
