Troubleshooting
A. Self-Diagnostics
The XRTV zoom camera is equipped with self-diagnostic features that help to
debug certain problems that may hinder system performance. This self-
diagnostic feature will help to identify if the x-ray source is emitting x-rays,
and if the camera control microprocessor and the camera itself are
functioning normally.
To use the self-diagnostic feature, power off the entire x-ray system at the
main power switch. Turn the system back on with the main power switch. Go
to the camera controls. The camera controls should be making an audible
beep and, if equipped with a lighted Zoom/Gain switch, the LED should also
be flashing. As soon as the beeping starts (about 4 seconds after start-up)
hold down the memory button until the beeping stops. You will notice that the
image processor will not boot up and that there will be no image on the
monitor. Depress and hold the footswitch. After about 3 seconds, the
camera control box should let out a continuous beep and the AGC LED (if so
equipped) should turn o n. Now release the foot switch and the LED should
turn off and the beeping should stop. The beeping and lighting of the AGC
LED signifies that the x-ray source is emitting x-rays and that the x-ray
converter inside of the camera is functioning properly. Now, press and
release the memory button. The camera control box should begin its start-up
beeping. This is testing the camera and microprocessor communications.
After about 5-7 seconds, the beeping should stop and a video signal will now
be present. Note that the image processor should now boot up properly and
an x-ray image should now appear on the monitor. If there ever was a
problem with your x-ray system, you may be asked to perform this test if you
call PACE for technical support.
B. Blurry Image
The XRTV Zoom camera employs an advanced focus system, which keeps
the image in constant focus. On occasion, the focus system will drift. This
problem occurs most often if the magnification is changed while the x-ray
source is not on. In most cases, the camera control system will refocus the
camera within 1-2 seconds. If the image appears out of focus for longer than
a few seconds, change the magnification setting while the x-ray source is on.
This should give the camera enough information to let it lock onto the proper
focus. In general, it is best to change the magnification only when the x-ray
source is on. Changing the magnification when the x-ray source is off will not
cause any damage; it will just take a few extra seconds for the camera to lock
into focus.
