Is the other problem MP277 at the same machine? It sounds like a bad grounding / bad equipotential bounding. You should check the powersupply first! |

I did see the word crane, reminds me off this : /tf/WW/en/Posts/54520#top So have a good lood at your powerlines and grounding, a crane is mobile so there could be some point where the power or ground can be broken for a short period. Best regards, Marcjan |
Problem solved? |
