Q: Why does my display show “NC”?

A: The “NC” means No Communication.

1. This will generally appear if you have an MCE M2000 or M4000 controller with a built in CE interface board and means there is no communication between the interface board and the controller, but the connection to the remote display is fine.  You will need to contact tech support at Motion Control Engineering to troubleshoot the problem.
2. This may also happen if you have a Thyssen TAC20/32/50 controller using the THY02 interface board and normally means there is no communication between the interface board and the controller.
