440 ATC
Reason: ATC board may not be getting voltage causing check fuses and cabling error.

If you have +48 Vdc but no lights on your ATC board, please contact Tormach Tech Support.
Check for voltage to the ATC board - Legacy ATC
Your ATC board should show the following LEDs lit if it has +48 Vdc at wires 503 and 504 at the ATC control board and is successfully talking to PathPilot.
...
If you have +48 Vdc at wires 503 and 504 at the ATC control board but no lights on the board, contact Tormach Tech Support.
If you do not have +48 Vdc across wires 503 and 504, move to the 48V Power Supply in the machine column. Measure for 48V DC on the power supply from the V+ and V- wires from the ATC. If the ATC won’t communicate and the ATC tab goes away, but the 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.
