X-ray generator messages and warning signals
Acoustic signals
The generator indicates particular states with acoustic signals:
• Exposure is terminated: 500 ms tone
• Errors: rapid series of tones
Visual signals
The generator indicates particular states with visual signals:
• Preparation: flashing of prepare ready indicator (green LED)
• X-ray tube is prepared: prepare ready indicator is continuously lit (green
LED)
• Exposure: radiation indicator is continuously lit (red LED)
Exposure termination
In normal operation the exposure is terminated by the generator when:
• mAs product is reached
• Exposure time is reached
• AEC switches off
If the exposure switch is released the exposure is terminated instantaneously
and an error is indicated.
In case of failure the exposure is instantaneously terminated when:
• AEC faulty
• Initial dose too high or too low with AEC (if function is activated)
• Maximum exposure time of 3.2 sec reached in 1-point technique with AEC
• mAs product of 600 mAs is reached
• Maximum permissible exposure time of 6.3 sec is reached (safety switch
off)
• Door contact is opened
