CAN communication troubleshooting for TorchConnect consoles
Diagnostic codes 503, 507, 508, 513, 600
Do these steps if you get a diagnostic code that is related to CAN communication issues with a
TorchConnect 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.

503 The TorchConnect console cannot receive commu-
nications (at least once-per-second) from the main

507 There is a problem with the CAN when power is
supplied to the cutting system.
All models None Remote on-off
508 The load on the CAN bus is more than capacity for
10 milliseconds or more.

513 The main control PCB cannot receive communica-
tions (at least once-per-second) from the TorchCon-
nect console through the CAN.
All models Ramp down Remote on-off
600 For a minimum of 30 seconds after power is sup-
plied to the cutting system, the TorchConnect con-
sole does not identify itself to the main control PCB
through the CAN.
All models Shut down Remote on-off
Corrective action
1. Remove the power from the cutting system.
2. Make sure that all connections between the TorchConnect console and the gas connect console are
fully tightened.
3. Make sure that the D43 (+5 VDC) LED and the D46 (+3.3 VDC) LED are illuminated on the control
PCB (141334) in the TorchConnect console.
4. Examine D43 (+5 VDC) and D46 (+3.3 VDC) on the control PCB:
