Siemens Multix Swing Err 0042

Hi, here is what you can try:

Check the high voltage; if the high voltage is generated to less than 20 kV (check on D500_X186 at Pin UTact), then -> replace the tube unit, but first readout/note the tube data.
If no high voltage is generated, check the oscillation current signal on D500, Pin X210_Iload -> if the oscillation current signal is present, there is a short circuit in the HVT or in the high voltage circuit; for this, check for a short circuit on D530 X13 and X11 if there is no short circuit, then: - Replace tube unit, but first read out/note the tube data
Determine the oscillation with the single oscillation Test, check the control (D500_X100_F_INV) and oscillation pulse (D500_X210_I_load): - 1) If there is no control, then replace the D500. - 2) If no oscillation pulse is generated, replace the inverter
