3 - 4 Troubleshooting
Err 17 Maximum exposure time (Max. exposure time reached)
- Filament current too low?
- mAs counter is set incorrectly (P1 on D915)?
Err 18 Exposure not completed (exposure not completed by the system - expo-
sure switch was released)
- Operator error?
- Intermittent contact in the release switch?
- Error in the exposure release circuit?
Err 20 Capacitor bank not ready
Device was not ready yet / had not released yet.
- F1 on D950 defect?
- Error on D950?
Err 21 Vfil > Vmax (Max. Filament heating exceeded during preparation)
- Error during the acquisition of the filament heating?
- Basic value of the exposure filament incorrectly set (P5 on D915)?
- Error on D915?
Err 22 Maximum preparation (preparation time too long)
- Prep level pressed too long.
Err 30 Fast capacitor charge (capacitor bank charges too fast)
- Are all fuses on the capacitor bank (D970) ok?
- Are there defective capacitors?
- Is the line voltage too high (> 250 V)?
- Is the charging frequency too high?
- Configure the capacitor bank.
- D950 defect?
Err 31 Slow capacitor charge (capacitor bank charges too slow
)
- ’V25’ (line) on D950 flashing? Check fuse F1
- None or insufficient charging frequency?
- Check D950 (’V22 - V24’ defective?)
- Poor connections to / in the capacitor bank?
Err 33 Inverter Error
- Check ribbon cable X20.
- FMAX not adusted?
- IGBT short - circuited?
Err 34 Filament Inverter short - circuit
- FMAX not adjusted?
- IGBT short - circuited?
Err 90 EPROM checksum
- EPROM defective.
Err 96 kVnom failure (hardware error , refer also to Err 5)
Err 97 mAnom failure (hardware error, refer also to Err 6)
