Hi,

Yesterday I positioned z-axes and moved manually down to the workpiece, while suddenly spindle turret made a silent clink and move slightly below to workpiece. After that, appeared some message on the screen for a moment. I didn't see, that was written on it, because computer closed all programs and alert/s. Eventually appeared message: "computer is now safe to restart" (or something like that). Computer shutted down. Now, the computer will not start.

I connected power supply to grid with external power cable and the computer started.

In elelctric cabinet, I found that one wire of power supply goes to communication board. Is it possible, that the wire is some impulse cable.

Conjointly, I checked fuses on output board and fuses below the transformer. All were okay.

Any advice will be helpful.
