A) Direction of movement for deinstalling the holddowns (left, right)

1. Conveyor assembly (fixed or movable side)

2. Rocker lever, fixed or movable side: DO NOT DEINSTALL

3. Setscrew M3 x 5

4. Ball bearing and spacer disk (remove for deinstallation of the lifting table plate)

5. Compression spring on the rocker lever

6. PCB guide rail (all remained installed)

7. Compression spring for holddown

8. Retaining bracket (support)

9. DU strip (3 units)

10. Cassette 1 or 2, guide for holddown

11. Cassette 3, guide for holddown

12.Adjusting shim 3 x 4.5 x 0.1 mm

13.Sliding strip 2 for holddown

14. Sliding strip for holddown

15. Holddown (to be deinstalled)

16.Fasteners for support: 2 slotted screws M4 x 6

Carry out the following steps on the fixed and movable conveyor side for each of the two pro-

cessing areas of the conveyor to be retrofitted (1 / 2):

Å Remove the 3 DU strips (see Fig. 2.5.2 -> 9) and the two guides for the guides for the hold-

downs (see Fig. 2.5.2 -> 10 and 11) on the exterior of the conveyor.

To do so, undo and remove the M3 cross-slotted and hexagonal socket head cap screws.

Being careful not to lose the adjusting shims (see Fig. 2.5.2 -> 12).

Å During the subsequent removal of the holddowns make certain that each of the 2 compression

springs (see Fig. 2.5.2 -> 7, 8) are not lost:

Å For dual conveyor: Now reduce the conveyor width somewhat by carefully moving the

toothed belt in the appropriate direction. Exert just a little force during this process and only

in the direction in which the toothed belt moves.

Å Fold the holddown device to the outside (direction of movement: see Fig. 2.5.2 -> A) and

take it off. While doing so, remove the compression spring from the retaining bracket (sup-

port): see Fig. 2.5.2 -> 7 and 8.

Å During this process, exchange the compression spring of the pertinent holddown (see Fig.

2.5.2 -> 7), if the spring is shorter than 32 mm when not loaded -> Item no. of compression

spring: see Section 2.4.2.

Å Install the appropriate holddown from the retrofit kit incl. the (new, if necessary) compression

spring with retaining bracket (support) on the conveyor assembly and install it in the reverse

order to the steps as described in Section 2.5.4 for deinstallation.

1. Holddown 1

2. Holddown 2

3. PCB holddown bracket on fixed and movable side:

Only for reinstallation on the PCB centering unit

(fasteners: 5 countersunk screws each M3 x 6).
