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 Controller Area Network (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.

Symptoms

Code Symptoms XPR® models XPR action Code cancels with...
503 The main control Printed Circuit Board (PCB) cannot receive communications (at least once-per-second) from the TorchConnect console through the CAN. All models Shut down Remote on-off
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. All models None Remote on-off
513 The TorchConnect console cannot receive communications (at least once-per-second) from the main control PCB through the CAN. All models None Remote on-off
600 For a minimum of 30 seconds after power is supplied to the cutting system, the TorchConnect console 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) Light Emitting Diode (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:​
    If you see this condition...Do these steps...
    D43 and D46 are not illuminated.
    1. Measure the power output for PS1 with a digital volt meter.
    2. If there is no 24 VDC output, examine the 120 VAC input to PS1.
    3. If there is no 120 VAC, make sure that the power cable connection is fully tightened between the TorchConnect console and the 120 VAC-out connection from the gas connect console.
    D43 and D46 are illuminated.
    1. Make sure that the 120 VAC-out cable from the gas connect console is fully tightened.
    2. Make sure that the Activity LED (D88) and the Status LED (D87) are flashing one time per second.
    3. If D88 and D87 are not flashing one time per second, replace the control PCB.

    A flashing or flickering LED shows that the microprocessor on the control PCB is functional. If D43 and D46 are good, continue with the next step.

  5. Examine the CAN TX LED (D35) and the RX LED (D34):
    If you see this condition...Do these steps...
    D34 is not flickering. Reconnect the CAN cable between the TorchConnect console and the gas connect console. Fully tighten the connections.
    D34 is flickering, but D35 is not flickering. Replace the control PCB in the TorchConnect console.
  6. If you cannot find or correct the problem, speak to your cutting machine supplier or regional Hypertherm® Technical Service team.
