Remedy
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, no-
tify Service.
Slope "Acknowledge error" signal (0 to 1) using the ro-
bot interface (if present).
Switch the machine off and on. If the error persists, no-
tify Service.
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).
value).
times if necessary.
Check the wear parts of the plasma torch.
Switch the machine off and on. If the error persists, no-
tify Service.
Switch the machine off and on.
If the error persists, notify Service.
Inform service.
Check the welding process.
Inform service.
Check the external shutdown devices. Check jumper
JP 1 on PCB T320/1.
Check the auxiliary drive (tacho – no signal, M3.51 de-
fective > notify Service).
Replace component.
