I've found that the SHUTTLE IN/SHUTTLE OUT RELAYS sometimes get sticky and the shuttle will time out. You night try cleaning the relay contacts or replacing the relays.
I'm having an issue with our 2004 VF-3. The proximity switches for the shuttle in and out are acting up. The switches test fine and they supply the correct voltage back to the I/O board. Though on the I/O screen they both say 1. The weird thing is that if I open the door to rear panel and wait a minute they will work right, but if i close the door I can watch the 0 turn to a 1 on the I/O screen and it will fault out. I installed all new fans and the cabinet filter thinking it was a cooling issue. I also replaced the I/O board. Still no luck. Any help would be greatly appreciated.

Thank you. I'll look into these cables.
I think I figured it out. The new mocon board has aluminium heat sinks on one part of the board. The old one didn't. it's working fine now that I got a spare from a retired haas tech.
