3.4 Errors 30-33 (generator errors)

Er 30 kV value does not reach given value
Er 31 mA value does not reach given value
Er 32 Tube filament control inoperative
Er 33 Tube filament control inoperative
Technical Manual
If the kV value remains more than 6 kV below the desired value (in service settings mode if kV
does not exceed 35 kV) this error is indicated.
- kV feedback cable short circuit
- Defective tube head
- Defective generator
- Defective generator processor board
- Check operating voltages and locate fault by replacing boards
- see Er 11
If the mA value remains more than 1 mA below the desired value (in service settings mode if
mA does not exceed 0.5 mA) this error is indicated.
- mA feedback cable short circuit
- Faulty tube head filament power cables
- Faulty X-ray tube filament
- Power generator tube filament power supply inoperative
- Defective generator processor board
- Check operating voltages and locate fault by replacing boards
- If it appears between Er 11 and continuous Er 30, most likely defective tube head.
If the mA value exceeds more than 1 mA the desired value during exposure this error is indi-
cated.
Error during exposure:
- mA feedback opened during exposure (try new exposure Er 32)
- Filament power supply broken during exposure (try new exposure to see if Er 33 occurs)
- Generator processor board measuring circuits broken during exposure. (Try new exposure
to see if Er 33 occurs)
After 2 seconds pre-heat period the tube filament voltage must be within 0.1V. If not, this error
is indicated.
Error in the beginning of the exposure:
- Generator operating voltage missing (mains)
- Tube filament short circuit
- Generator board filament power supply defective (likely when after Er 11)
- Check operating voltages and locate fault by replacing boards.
