Hardware/Software

Critical

Fault Description

This fault triggers when the UL2202 Annex C code decides there is a safety critical fault on one of the LCCClosed Liquid Cooled Cable cables (UL2202 Annex C does not apply to non-LCCClosed Liquid Cooled Cable cables). The loop runs continuously. The exact cause of the fault will be sent as a separate fault.

Troubleshooting

Look for the exact fault sent out and follow troubleshooting steps for that fault code.

Hardware/Software

Critical

Fault Description

The CAN traffic to the Phoenix cable has dropped three (or perhaps six) consecutive packets.

Possible Causes

Troubleshooting

  1. Check if the SEVBClosed Smart Ethernet Vehicle Board firmware or any hardware has been changed recently on the Power Link 2000. Reboot SEVBClosed Smart Ethernet Vehicle Board/Power Link 2000 to force a power cycle on SEVBClosed Smart Ethernet Vehicle Board. Check if this clears up the fault.

  2. If software was updated, leading to this fault, then re-flash the firmware and check if the issue resolves.

  3. If hardware was updated, leading to this fault, then check if all connectors are seated correctly. If any are disconnected, then re-seat them and see if the issue resolves.

  4. Contact engineering if the issue persists.

Critical

Fault Description

This fault is declared when the CAN traffic from the Phoenix cable has temperature data outside the expected range.

Possible Causes

Troubleshooting

  1. Check if the SEVBClosed Smart Ethernet Vehicle Board firmware or any hardware has been changed recently on the Power Link 2000. Reboot SEVBClosed Smart Ethernet Vehicle Board/Power Link 2000 to force a power cycle on SEVBClosed Smart Ethernet Vehicle Board. Check if this clears up the fault.

  2. If software was updated, leading to this fault, then re-flash the firmware and check if the issue resolves.

  3. If hardware was updated, leading to this fault, then check if all connectors are seated correctly. If any are disconnected, then reseat them and see if the issue resolves.

  4. Contact engineering if the issue persists.

Hardware/Software

Critical

Fault Description

This fault triggers when the cable's positive terminal temperature exceeds the limit of 89 °C.

Possible Causes

Cable internal joint failure.

Troubleshooting

Contact engineering for the debugging steps if this fault triggers three times in 24 hours.

Fault Type

Criticality

PL_LCCClosed Liquid Cooled Cable

PL_Cooling

Hardware

Critical

Fault Description

This fault triggers when terminal temperatures are still above 84 °C and when the current is below the rated 200 A. The fault clears with UL-Stop and when terminal temperatures reach below 80 °C.

Possible Causes

  • Issue with cable cooling.

  • Cable internal conductor issue.

Troubleshooting

  1. Run Power Link 2000 self-test to confirm if the system is functioning as expected.

  2. If this fault triggers on more than three consecutive sessions, replace the cable to resolve the issue (refer to the Power Link 2000 Service Guide).

  3. Contact engineering if the issue persists.

Critical

Fault Description

This fault triggers when the SEVBClosed Smart Ethernet Vehicle Board RTD temperature is below 70 °C for 10 seconds.

Possible Causes

Hardware failure.

Troubleshooting

  1. Replace the cable to resolve the issue (refer to the Power Link 2000 Service Guide).

  2. Contact engineering if the issue persists.
