Image Control
Image Intensifier and Power Supply
Using copper filters, successively add filters onto the II surface. Observe the image and verify that the system compensates for
each added filter, boosting the brightness and contrast of the monitor image as the filters are added.
WARNING: The following procedure generates X-Rays. Take appropriate precautions when
performing this procedure.
The Fluoro Functions PCB controls the following camera motor functions:
• Camera Iris (Open/Close)
• Camera Optics (Rotation)
• Collimator Leaves (Open/Close)
• Collimator Leaves (Rotation)
• Collimator Iris (Open/Close)
A failure on the Fluoro Functions PCB may result in an array of symptoms. Some failures may result in an error message being
displayed on the Mobile C-Arm’s Control Panel.
WARNING: Do not measure the output of the power supply to the Image Intensifier tube. A lethal
anode voltage exists on this connector.
Check the output of Power Supply PS2 and make sure the output voltage is +24VDC.
Using a voltmeter, measure the +24 volt supply to the II power supply at J7, between pins 15 - 8 and at the output of Power
Supply PS2. If problems are noted in changing from small to medium fields, check the MD_FIELD signal on pin 14 of J7. The
SM_FIELD signal is on pin 6 of J7.
