• Installation of drive adaptor with drive adaptor safety catch on
drives R8/17R to R20/17R:
The feed direction of the drive adaptor safety catch is preset by its shape.
When inserting the drive adaptor safety catch, make sure that the locking
lug engages. You can tell by an audible click. Check that the catch is se-
curely located by pulling on the drive adaptor (Fig. 4).
• Installation of drive adaptor with screw connection on drives R30/
17R to R40/17R:
In this case an M6x12 screw is used for fastening. This is secured with an
M6 plain washer and an appropriate toothed washer (Fig. 4)
3. Connect the driver of the tubular drive to the roller tube properly, as fol-

BECKER-Antriebe GmbH recommends that the limit switch adaptor is
also screwed to the barrel.

• On shaped section barrels:
Mount the drive with the appropriate limit ring adaptor (A) and drive adap-
tor (B). Insert the drive with the pre-mounted adaptors into the barrel so
that it locks positively. Make sure that the adaptors are securely located in
the barrel (Fig. 5).
Tolerances in the slot widths in different barrels can, with some drive
adaptors, be equalised by turning the drive adaptor into an-other slot re-
cess. These slot recesses have different dimensions and enable you to
accurately fit the drive (Fig. 6).
• On round barrels:
First notch the tube on the motor side, so that the key of the limit collar can
also be pushed into the barrel. There must not be any play between the
limit collar key and the barrel (Fig. 7).

Attention
When using locking straps enclosed bearings must be fitted.
The tubular drive presses the closed shutter down to prevent
anyone from grasping the bottom rail and pushing it up. Only
use shutters made of sufficiently strong material, such as alu-
minium, steel or wood. To avoid damage to the shutter it must
run in guide rails from top to bottom.
