Replacement procedures 2

Replace the plastic tray 2

Plastic tray with frame, former version, unmodified.

2 - 1

NOTICE

1. Loosen the four screws (1/Fig. 1) and remove the plastic tray from the frame.

Fig. 1

When replacing the plastic tray, always replace the frame as well.

(The new frame is delivered with the new plastic tray.)

2. Loosen the two Allen screws (2/Fig. 1) and remove the frame from the support.

3. Fit the new frame to the support and fasten with the two Allen screws (2/Fig. 1)
and washers.

4. Then fit the new plastic tray to the frame and fasten with four new screws (1/Fig. 1)
and washers, but do not screw tight.

NOTICE

Check that the plastic tray is correctly inserted regarding the AEC
detector markings (3/Fig. 1).

Plastic tray with frame, newer version, modified. 2

In order to improve the reliability of the plastic trays some frame fixations have been mod­ified.

In the first step the fixation of the plastic trays, material number 64 83 809 and 64 83 817
were modified, the four screws (1/Fig. 1) are being led inside of special plastic bushings
(Fig. 2). These bushings have to be inserted from inside of the tray, their collar staying
inside (see Fig. 3)

2 - 2 Replacement procedures

CAUTION

The exchange procedure is self explanatory following the description above.

NOTE

Correct torque.

If torque is out of tolerance, either the fixation will be weak or the
bushings will get damaged.

Tighten all 4 screws by a torque of 0.45 Nm +

In future there may be other material numbers from the table
"Plastic trays with frame" delivered with such plastic bushings.

In such cases follow this part of the instruction.

Strictly adhere to prescribed value of the tightening torque.

2 - 4 Replacement procedures

Flexible plastic tray and rubber springs 2

NOTICE

When replacing the flexible plastic tray, always replace the rubber
springs, nuts, bolts and washers, as well. (Actually the entire kit
should always be replaced, the used materials properly disposed
off.)

1. Loosen the four screws and nuts (1 and 3 / Fig. 5) and remove the plastic tray from
the frame.

2. Fit the four new rubber springs (2/ Fig. 5) to the new plastic tray. Make sure the
rubber springs are properly positioned. (One rubber spring is delivered as reserve,
if damage by fitting it into the hole should occur.)

3. Fit the new plastic tray to the frame on the support and fasten it with the four new
screws and nuts (1 and 3/ Fig. 5). Do not forget to insert one washer 066 16 259
each between the outer collar of the rubber spring and the inner part of the frame
(as indicated by the arrow 4 / Fig. 5). The washers are meant to prevent
unprotected rubbing of the spring on painted inner surface of the support frame in
case of flexible compression plates.

NOTICE

When the screws are tightened there is still a small gap between
the frame and the plastic tray. This is to allow for the tray to move
slightly up and down. (It is a "Flexible compression plate"!)

Adjustment procedures 3

Final check and adjustment of the compression plate 3

After replacing a plastic tray, the compression plate must be checked and adjusted.

Flexible compression plates and spot compression plates do not need further adjustment.

Low edge compression plate

3 - 1

NOTICE

The instructions on this page only apply to low edge compression
plates (18 x 24, 24 x 30, Axilla, Mag 1.5 and Mag 1.8).

1. Attach the compression plate to the compression unit (ensure that the
compression plate is fully inserted).

2. Place a non-compressive object, for example a 10 - 20 mm thick Plexiglas plate,
on the object table. The plate must cover the object table.

3. Lower the compression plate to the Plexiglas plate. Apply a compression force of
3 - 5 kg. The plastic tray will now adjust itself so that it lies flat against the Plexiglas
plate. Before tightening the four screws, check the alignment of the compression
plate and the object table at the front edge (chest-wall side) (Fig. 1). Adjust by
displacing the plastic tray, if necessary. Tighten the screws.

3 - 2 Adjustment procedures

High edge compression plate 3

NOTICE

The instructions on this page only apply to high edge compres­sion plates (18 H and 24 H).

This adjustment is necessary to ensure that the front edge does not show on the film.

1. Attach the compression plate to the compression unit (ensure that the
compression plate is fully inserted).

2. Place a non-compressive object, for example a 10 - 20 mm thick Plexiglas plate,
on the object table. The plate must cover the object table.

3. Lower the compression plate to the object table. Apply a compression force of
3 - 5 kg. The plastic tray will now adjust itself so that it lies flat against the Plexiglas
plate. Attach the adhesive gauge block to the front of the object table (chest-wall
side). Make sure the piece is perpendicular to the object table and laterally placed
at the center of the compression table (1/Fig. 2).

4. Raise the compression unit and adjust the compression plate so that the bottom
and the center fits the adhesive gauge block when a compression force of 3 - 5 kg
is applied (2/Fig. 2).

5. Tighten the four screws.

6. Remove the adhesive gauge block.
