If you see this condition... Do these steps...
D24 and D25 are not illuminated and
are not flickering.
Reconnect the CAN cables to the plasma power supply and the cooler.
D24 is not illuminated, and D25 is
flickering.
1. Examine the control PCB in the gas connect console for shorts.
2. Look for a shorting block across pin 1 and pin 2 of J16.
3. If there is a shorting block, remove it and start the cutting system again.
4. If J16 is open, replace the control PCB.
9. If you cannot find or correct the problem, speak to your cutting machine supplier or regional
Hypertherm Technical Service team.
CAN communication troubleshooting for mixing modules in
OptiMix consoles
Diagnostic codes 501, 507, 508, 511
Do these steps if you get a diagnostic code that is related to CAN communication issues with the mixing
module in an OptiMix gas connect console.
Multiple CAN diagnostic codes at the same time can identify a problem with the CAN cable. If there is only
one code, the problem is more likely to be caused by what the code says and not by the CAN cable.
