Replacing boards / replacing components
I.I.
•
Mount the I.I. back on the C-arm flange. The labels should face the C-arm.
•
Reinstall the attachment screws in the threaded holes. Turn them at least 5 revolutions.
•
Holding the I.I. firmly, swivel the C-arm so that the I.I. is above and the SIREPHOS is be-
low.
•
Carefully lower the I.I. into the service position.
I.I. Mini voltage supply
•
Reinstall the high voltage section of the I.I. mini voltage supply.
•
Reconnect the control section, however, do not tighten the screws yet.
•
Route the cables to the high voltage section and the control section and secure them
with cable ties or cable clamps.

VIDEOMED DC

•
Rotate the Compact optics into the 0° position (slowly!).
•
Connect an ohmmeter to the potentiometer for camera rotation, point 2 and 3.
At 0° , there should be a resistance value of 5000 ohms, + 40 ohms.
•
Place the VIDEOMED DC in the 0° position on the compact optics and secure it with the
clamp. Refer also to chapter 6, Replacing the VIDEOMED DC.

Miscellaneous parts

•
Mount the grid to the new I.I. Attach the wires for the cassette contact.
•
Reroute and reconnect all the cables (protective conductor, cables etc....).

Checks and adjustments

•
Check the I.I. electrode voltages according to the test protocol for the I.I. and adjust
them.
•
Check the resolution. If necessary, adjust the optical sharpness on the Compact optics.
•
When doing this, use the I.Q. Quick test, chapter: Resolution for evaluating the optical
sharpness.
•
Check the dose rate and, if necessary, adjust it.
•
Check that the camera optics are centered to the I.I. output and, if necessary, adjust
them. Refer also to chapter 6: Replacing the Compact optics, paragraph "Checking the
camera optics centering at the I.I. output" and "Centering the Compact optics to the I.I.
output".
•
Check the camera rotation and, if necessary, adjust it.
