Capacitor charge error
- Has the system not been used for a longer period of time
(higher capacitor leakage current)?
➪
- Are the discharge resistors permanently connected?
- Has the temperature sensor on D950 responded
(D950 TP 'TP')?
- Has overvoltage in the C-bank been detected? (D950 TP 'VC')
- Is there a short on D950? The error appears only when the short circuit is
continuous.
Replace D950.
+ 15 V - Error
- Check the fuse on power supply U1.
- Is power supply U1 defective?
Vfil < Vstby (none or insufficient filament current)
- Do 'V1' (-DC) and 'V2' (+DC) flash on D925? Otherwise check fuse F6.
- No filament frequency? Check D915 .
- Connection D925 =>X-ray tube unit (X5).
- ConnectionD925 => D915 (X11).
- Check X-ray tube assembly.
- D925 defective.
Vfil > Vstby (filament current is too high)
- Do 'V1' (-DC) and 'V2' (+DC) flash on D925? Otherwise check fuse F6.
- Filament frequency too high?
- A/D converter on D915 defective? => Replace D915.
- Short-circuit at the output of the filament inverter =>check connection to/in
the X-ray tube assembly.
≠
KVact 0
- No connection to the single tank generator (D915 X8)?
- Plug-in connection on D900 in the single tank generator ok?
≠
mAact 0
- Error in the measurement acquisition on D915? => Replace D915 .
- No connection to the single tank generator (D915 X8)?
- Plug-in connection on D900 in the single tank generator ok?
≠
Rot 0 (rotating anode speed
- Error on D915 or D925.
If the error occurs after switching the system off and back
on again, configure the capacitor bank
(refer to the "Service program" chapter, pages 4-2).
