    That is a circuit breaker/Thermal overload trip. Someone plug something in to the 110v plug on the machine?

    Yes, our sending and receiving unit for programs. We unplugged it and tried restarting and still won't do anything? Is there something we can reset?

    Yes, look for a tripped breaker in the cabinet. IF i remember correctly, that one is mounted on the door. It should be labeled CB1

    Our CB1 is not mounted on the door and it doesn't have a reset on it. Attachment 196094 See the picture of fuses, only one light comes on these fuses, and it is the first one to the left. Any other suggestions?

    Keep looking. Those are relays. Won't be a fuse. It will be a circuit breaker.

    I wanted to let you and anyone else having this problem know that the Alarm A106 E Overload actually stems from the Alarm 201-3 Alarm A Servo Amp X-Axis 2C6, we had to replace the BLII-D50-50A Dual Axis AC Servo Drive A006-0629 2-50 AMP A-TYPE E4809-770-065 SVCII-A Board. I wanted to Thank you for giving us a starting point of which lead to solving the problem. Also, Okuma wanted $6,500.00 for this, we went to Precision Zone and did an exchange for $3,000.00.
