12- 3 Other Operator Fault Analysis
TABLE 12-3
OPERATOR FAULT ANALYSIS
Fault
Recommended Action
System circuit breaker on
and LCD display is dark.
Verify:
– Power line is plugged into the receptacle or connected to the main circuit breaker?
– Power is available at the receptacle or the main circuit breaker?
– The remote ON/OFF switch on the System Console is in the
ON
position?
No exposure.
Are any error messages displayed?
Image quality.
– Motion artifacts?
Relax the patient. Make the patient as comfortable as possible. Check once again for
proper positioning.
– Insufficient contrast? Decrease kVp.
Check the dark room, film expiration date, chemicals and developer temperature.
Fault Reset (AEC).
Verify:
– Proper chamber selected?
– Chamber connected?
– Film speed correct?
If the film is too dark, decrease density.
If the film is too light, increase density.
12- 4 Resetting Faults
When AEC mode is enabled, exposure time/termination is controlled via
ionization chamber sensing circuits. In addition, a back-up time is programmed
into the system to help prevent excessive patient dose in the event of an AEC
system malfunction. If the exposure time equals the back-up time, exposure will
be terminated and a fault message will appear across the bottom of the screen.
To clear the fault, press the function key by the flashing
FAULT RESET
field. If
the fault persists, the system should be used in manual mode until the fault can
be isolated/corrected.
