*
The generator purges the existing X-ray tube auto calibration data before starting the auto calibration
routine and saving new calibration data. Therefore, auto calibration should be a last resort during
general troubleshooting, and should only be done to recalibrate the tube. For example, if a low mA
fault is presented, you should ensure that the generator is fully functional, and actually needs
recalibration. If calibration is attempted on a partially functional generator, the auto calibration routine
may be aborted before any calibration is done, and the generator will inhibit further exposures until the
selected mA is calibrated for the selected kV.
1. For an APR MEMORY ERROR fault, the console factory defaults must be restored or the APR must
be restored via GenWare®. The procedure for resetting console factory defaults is described in
chapter 6.
5.3.0 MISCELLANEOUS FAULTS
5.3.1

Erratic Console Faults

SYMPTOM: In some environments that are "electrically noisy", the console may exhibit erratic faults i.e. RAM
data error, intermittent loss of communication, or random fault messages may be displayed.
SOLUTION: Connect a separate ground wire, #14 AWG (2.3 mm
of the console (marked CONSOLE GROUND in the figure "Rear of control console" in chapter 2)
to the ground stud located beside the main input fuse block. This is marked GROUND
CONNECTION in the figure "Generator mains connection" in chapter 2.
SYMPTOM: In some situations the touchscreen console may appear "frozen". i.e. cannot activate any of the
buttons on the touch sensitive screen. This may be a case of the touchscreen calibration being
significantly out of alignment.
SOLUTION: Connect a USB keyboard to the rear of the touchscreen and simultaneously press Alt + C. This
will activate the touchscreen calibration sequence. Refer to Chapter 3C for the procedure to
complete this sequence.
