NICOL X-Ray Beam Limiting Device Fault Finding

3 FAULT FINDING

NOTE

NOT described in this document, is how to find to an FRU,

based on error messages, which are sent from the BLD to the system via the CAN.

This is described in the applicable system documentation, see the relevant system reference manual.

________________

NTRODUCTION

3.1 I

This chapter describes:

• indicators and measuring points for each PCB

• miscellaneous complaints and/or problems

Also for each problem, possible fault causes and/or solutions are given.

However to get feedback from the field as soon as possible, a very high FRU level is defined. So only a very limited spare parts list is available.

In case of problems, the complete BLD has to be exchanged. The defect BLD, together with a clear

NOTE

problem description, has to be returned to Best as soon as possible!

AULTFIND STRATEGY

3.2 F

It is advised to start/perform faultfinding based on error messages as described in the relevant system documentation, see system reference manual. Only if this is not possible, or does not lead to a solution for the problem, this chapter may be of help. The faultfinding directly points to some basic FRU’s (PCB’s and BLD) and a few FRU’s which are cheap and easy to replace.

3.3 INDICATORS

LED indicators are present on PCB’s LA2 and LA3. The explanation of the LED indicators is given in Table 10 and Table 11. The location of the LED’s on the PCB’s is given in Z3-2 to Z3-3.

NTRODUCTION

For perfect attachment of the BLD to the X-Ray tube housing, it is necessary that the BLD axis coincides with the median perpendicular line that passes through the center, between the two tube foci. Use BLD alignment tool, see Figure 32, page 50. Ideally, the resulted picture consists of two concentric circles. In reality there will be different pictures for small and large focus, see

Figure 22

, page 41.

6.1.2 TOOLS REQUIRED

OUNTING THE

BLD A

The BLD alignment tool can be mounted:

• if the coupling flange assembly is not mounted, first perform this procedure as described in paragraph 2.2.2, page 18.

• if the coupling flange assembly is mounted, similar procedure as for BLD mounting, see paragraph 0, page 19.

6.1.4 C

HECKING THE CENTERING FOR

To check the BLD centering relative to the X-Ray tube, proceed as follows:

1. Prepare a film cassette (with screen) oriented in the plane perpendicular to the central ray, with the edges of the film parallel to the longitudinal axis of the tube.

2. Set the following data: 65kV, 30mAs, SID=100mm (or more)

3. Make an exposure with small focus (SF)

Develop the film and determine:

• the center MA of the projection of ring A (see Figure 20)

• the center MB of the projection of ring B (see Figure 20)

• Draw the system coordinates on the film in the A-direction and B-

direction with reference to the film edges. (the positive directions can be derived from the mark at the right-hand top of the film)

4. Measure the distances P and Q on the film

5. Make an exposure with
