Specifications

Determine the total thickness of the supplied spacer(s) that must be added to the
collimator mounting surface to obtain a focal spot to collimator mounting flange
distance of 2-7/16” (2.44 inches, 62 mm) +/- 1/32” (.031 inches, 1 mm). Refer
to Figure 2-3.
Remove the upper swivel ring from the collimator by removing the 6-32 socket
head cap screw and opening the clamp ring.
In order to insure a safe and secure mounting of this collimator to the X-Ray tube
housing, the following installation guidelines should be followed.
1. Two different lengths of screws are provided in the cloth bag containing
the spacers. Determine the correct length of screw to use, taking into
account the collimator spacing requirements and/or peculiarities of the
tube housing port boss.
2. Clean the screws and housing port boss with alcohol and if necessary,
remove any debris which may be present in the tube housing mounting
holes.
3. SECURELY fasten the upper mounting flange and spacers to the
collimator mounting surface. As a precaution, a medium strength thread
locking compound, such as Loctite #242, should be applied to the screws
before fastening the collimator mounting ring to the tube housing.
Verify that the collimator mounting screws engage the housing by at least
five (5) threads when used with any required collimator spacer plate(s).
4. Carefully support the collimator in place and re-attach the clamping ring.
The hinge of the clamping ring must line up with the pin in the lower
mounting ring. Apply Loctite to the 6-32 socket head screw holding the
clamping ring and securely fasten together.
5. After mounting the collimator and/or performing any service to it or the
tube housing, inspect the fit of the collimator and tube housing. Grasp
and attempt to move the collimator and then the tube housing assembly
while inspecting for loose joints or gaps between the tube/collimator
assembly as well as other tube mounting areas.
WARNING! FAILURE TO ADHERE TO THE ABOVE GUIDELINES MAY
RESULT IN LOOSENING, DAMAGED SCREWS, OR MOUNT FAILURE
WHICH CAN RESULT IN HEAVY COMPONENTS FALLING DURING
USE. INCIDENTS OF LOOSE SYSTEM COMPONENTS SHOULD BE
REPORTED IMMEDIATELY TO X-RAY SERVICE FOR REPAIR.
