Mounting the Compact optics

NOTE
•
Reinsert the rubber gasket between the I.I. output and the camera optics. Reattach the
Compact optics to the new I.I.
Insert the anode cable through the opening in the optics.
The Compact optics must lie against the excenter screws.
•
Adjust the camera rotation of the Compact optics to the "0" position (6/Fig. 6).
•
To do this, connect an ohm meter to the potentiometer for camera rotation, location 2
and 3 (5/Fig. 7).
The resistance must measure 5000 ohms +/- 40 ohms in the middle position.
•
If necessary, adjust the camera with the clamping ring (1/Fig. 7) by rotating it to the
correct position.
•
Install the Videomed DC in the "0" position on the Compact optics and secure it
(6/Fig. 6).
•
Connect the Videomed DC - Compact optics cable and secure it with cable ties.
Make sure that the cable does not protrude past the edge of the board and that it lies in
the recess of the Videomed DC board.
•
Insert the anode cables for the high voltage panel back into the C-arm (3/Fig. 5).
•
Reinstall the O-ring and the cap nut on the anode cable.
The cable length should be 70 mm from the beginning of the white wire to the cap nut.
•
Reinstall the high voltage panel in the C-arm and reconnect all the cables.
•
Mount the retainer clip above the Videomed DC.
•
Reconnect both jacks, D4.X1 for the Videomed DC and X45 for the cassette contact to
the retainer clip.
•
Connect plugs D4.X1 for the Videomed DC and X45 for the cassette contact.
•
Connect plug M30.X1.
•
Connect plug D120.X1 to the control panel of the I.I. mini voltage supply.
•
Reconnect the protective conductor with the ground screw (5/Fig. 5).
•
Reinstall the cable clamps (3/Fig. 6).
•
Attach 2.1 mm Cu and 60 mm Al prefiltration to the radiation port of the Sirephos.
•
Attach the resolution test to the I.I. input screen and check the optical resolution.
Readjust it if necessary.
•
Remove the resolution test from the I.I. input screen.
•
Check the dose rate and readjust it if necessary.
