What kind of I/O do you have? separate remote boards? In some cases the fault can be pinned down by removing the Honda plugs one-at-a time to eliminate which is the offending I/O.

Here's a photo of the cabinet. Upper left I have all the honda connectors.

Do you have any remote boards out on the machine?
What is the number of the board with the Honda's plugged in?

I've been waiting for the replacement fuses to arrive. I looked for a number on the honda connector board but didn't find it. I need to look some more with a mirror tomorrow. Here's a couple photos. Sorry they are sideways.

I finally replaced the fuse that blew and promptly blew it again when I attempted to power the control. Last time, if you recall, the control posted and ran for a minute or two. Going downhill.

I realize it has been a couple of months. Finally had Mike from CNC Machine Service come down and diagnose the machine. Everything except the control power supply checked out. He installed the new power supply today and the machine is finally back up and running.

Thank you to everyone for your assistance and ideas. Just as the manual stated... if you blow fuses F1 and F2 on the input board... the power supply is bad.

Just bringing this machine online after being moved. I suspect the estop is related to the now missing pallet changer.

I've attached a photo of what I think is the Fanuc Input Unit. The leds PIL and ALM are both off. Fuses are all good. Voltage at R and S is 212V. This is a 208 3 phase system. The online maintenance manual, which is newer than my hard copy has some tests. Being that the fuses are good and the green PIL led never comes on it appears to be a bad power unit. The power unit they are describing is the input unit or the upper power supply? See the picture below.

Thanks for your help. I couldn't find the PIL and ALM leds for the life of me.

Can you please share that manual in the attached picture?

Both fuses appear to be blown (the white flag is shown). Problem is likely the power supply. I probably have a good one I can sell.

This is the manual I used:

+1 to what memoryman suggests. We replaced the power supply and it has worked perfectly.
