Thread: Machine Not powering Up

We have an Integrex 400Y with Fusion, when we came in this morning and hit the power on button nothing would happen. Screen will not come on and none of the servos lights come on as well. Power coming into the machine checked good and when we turn on the main breaker the cooling fans kick on. Checked the On Power Switch on the front of the screen and it is making good contact. I suspect a power supply, but not sure which one to check. Any ideas or suggestion would be greatly appreciated.
Thanks in advance.

When you turn the main breaker on, the servo drives should show an Ab (I think) on them until the pc boots up and they initialize. Power supplies should have led's on or something. Nothing is alive in the Electrcal Cabinet after the main breaker except the cooling fans?

I would check the 24v power supplies. Cant recall exactly where they are at on a Int 400. I want to say they are on the bottom right of the electrical cabinet. I'm working on one today I'll look and see.

If you could check and see where you have power and where you don't. that would help out. seems like you have 100v but no 24V.

the 24v power supply is in small electrical cabinet on the back of the machine. It is on the very bottom. There is a green LED on it to see if it working. Let us know what you find.

Yep, turned out to be a dead power supply. Ordered one from Mazak and installed it and it fired back up. Thanks for your help.
