1. Inspect your ATC board for LED lights that are illuminated. If you have no lights at all, move to the step.
2. If you have lights on your board but still no communication, ensure all wires are properly seated and secured in the terminals on the ATC board itself and try and reseat the connector
3. Check for
68V DC 68 Vdc across wires 204 and 205 at the ATC control board.  Image Modified
4. If you do not have +
68V DC 68 Vdc across wires 204 and 205, move to the DC bus board in the electrical cabinet and check the F8 fuse for continuity. If you do not have continuity, replace the fuse.
Note: This value should be close to zero and absolutely no more than 5 ohms.  Image Modified
5. If you have +
68V DC 68 Vdc but no lights on your ATC board, please contact Tormach Tech Support.

Your ATC board should show the following
LED’s LEDs lit if it has +
68V DC 68 Vdc at wires 503 and 504 at the ATC control board and is successfully talking to PathPilot.  Image Modified
2. If you have +
68V DC 68 Vdc at wires 503 and 504 at the ATC control board but no lights on the board, contact Tormach Tech Support.
3. If you do not have +
68V DC 68 Vdc across wires 503 and 504, move to the DC bus board in the electrical cabinet and check the F8 fuse for continuity. If you do not have continuity, replace the fuse.
Note: This value should be close to zero and absolutely no more than 5 ohms.  Image Modified
4. If the ATC won’t communicate and the ATC tab goes away, but the
Power Drawbar does open/close and the status page power drawbar opens/closes and the Status tab shows when the USB is removed and replaced, then inspect the RJ11 (DB3) cable for damage. Reseating and/or replacing this cable may be necessary as it may have became damaged or have an intermitted short.  Image Modified
5. If you continue to experience the check fuses and cabling error, contact Tormach Tech Support.
