During fluoroscopy there is not x-rays but also there aren't any errors. KV and mA on display are zero both in manual setting and automatic mode. I think that kontactors QK1 and QK2 in converter are not activated but what is the reason? I'm appreciated for any help.

Super 50 DO is part of DORNIER HM3 lithotripter and it has two x-ray tubes and two TV chains. It's used only for fluoroscopy with both tubes. When I swiched on fluoro from remote hand switch got led and buzzer for x-rays,but really there is no x-rays. It's same for both tubes and for mannual and auto settings of kV and mA. I found that PRON signal is HIGH (should be low to activate conntactors QK1,2,3 for high voltage). I have only schematic diagrams without any explanation.
Also there is filament curent and it is changed if I mannualy change mA's.

Does the fluoro light on the desk comes on? Does it expose on small focal spot? Have you done Fluoro from the generator cabinet?
