One of the problems is - as the title implies - the machine's immense hunger for power. It consumes about 5 kW, which at 380 V makes little less than 14 A.
Another problem is that a PSU (H7189-A) refuses to function as it's supposed to. A small lamp indicates OVERCURRENT. Very concerning indeed. (We have, after investigation, come to the conclusion that it might be a result of one of the three phases' fuse that blew...oh, well.)
DEC Östersund agreed to loan us some hardware-manuals - on microfiche! Well, mountains are made for moving. We ran to the City Library, scanned the 800 pages of manual, and came up with - nothing. Not that the manual is bad, probably just us being to eager learning all about it. We'll probably come around soon. Many thanks to DEC!
