This chapter contains general instructions about the installation of the BLD. For specific information at
system level, refer to the relevant system reference manual.
2.1.1 TOOLS & TEST EQUIPMENT
• Standard Service Toolkit
• BLD alignment tool, code number 4522 980 31521, available from Service Logistics Best.
2.1.2 S
The BLD is delivered as part of a pre-installed system or in a single package, always containing:
2.2 I
Whenever replacing a BLD, no centering is required, provided the coupling flange is left on the X-Ray
UPPLIED ITEMS
• BLD (including aesthetic cover)
• Coupling flange assembly (to mount and adjust the BLD on the X-Ray tube housing)
• Four countersunk screws (M6x25mm) (used for mounting the shipping bracket to the coupling
flange, also are intended to mount the coupling flange to the X-Ray tube housing)
• Service Manual (No Operator Manual supplied)
NSTALLATION INSTRUCTIONS
• Remove the items from the packing and check them against paragraph 2.1.2 Supplied Items,
for completeness.
This chapter describes the mounting procedure in case a pre-aligned X-ray Tube Assembly is used.
• Unscrew the locking plate screw (item 5, Figure 3, page 19) from each of the two locking plates
(item 1, Figure 3) and push them outwards as far as possible.
• Remove the shipping bracket (item 2, Figure 3) together with the coupling flange (item 3, Figure
3) from the BLD
• Unscrew the shipping bracket from the coupling flange (countersunk screws M6 x 25 mm must
be reused to mount the coupling flange on the tube housing.)
NOTE
Check the screw required length (25 mm) in the applicable tube housing service documentation.
At least 5 mm must be screwed into the tube housing.
________________
• Place the coupling flange (item 1,
Figure 1) on the X-Ray tube
housing (item 2, Figure 1) with
factory mounted alignment ring
(item 3, Figure 1)
• Positioning the reference pin (item
4, Figure 1) to the notch (item 5,
Figure 1) of the alignment ring.
Secure it with the four countersunk
• Unscrew the locking plate screw (item 5, Figure 3, page 19) from each of the two locking plates
(item 1, Figure 3) and push them outwards as far as possible.
• Remove the shipping bracket (item 2, Figure 3) together with the coupling flange (item 3, Figure
3) from the BLD
• Unscrew the shipping bracket from the coupling flange (countersunk screws M6 x 25 mm must
be reused to mount the coupling flange on the tube housing.)
NOTE
Check the screw required length (25 mm) in the applicable tube housing service documentation.
At least 5 mm must be screwed into the tube housing.
________________
• Place the coupling flange (item 1, Figure 2) on the X-Ray tube housing (item 2, Figure 2),
positioning the 0° notch (item 5, Figure 2) to the rear of the X-Ray tube housing, and secure it
with the four countersunk screws M6 x 25 mm, item 3, Figure 2. (see note above)
Figure 2: Mounting the coupling flange assembly
2.2.3 CENTERING THE BLD WITH RESPECT TO THE X-RAY TUBE
All BLD functions have been accurately centered in the factory, relative to the central axis; any further
centering has to be done by adjusting the coupling flange assembly of the BLD with respect to the XRay focus. The specified alignment tool must be used.
The centering procedure is described in paragraph 6.1.4, page 40.
This procedure must be carried out:
• After replacement of NICOL DISC 4522 300 2417x
• After replacement of the X-Ray tube, configurations A and D of Table 3.
