1.
Determine the length of the rotating union (Figure

)
B = Counter bearing / Bearing capsule
C = Drive end bearing / motor
Measure the wall gap of the drive bearing (13) and counter bearing
(1) as shown.
Measure the roller shutter box and calculate the required shaft
length (L).
Length of the rotating union: L = A - (B + C)
Shorten the rotating union (5) to the required size.
Cut the shaft to size with a hacksaw at a right-angle. Remove the burrs from the shaft
internally and externally with a file.

Mounting / dismounting the adapter (Figure

)
Mounting the adapter (10)
Slide the adapter (10) over the magnetic ring (19) on the drive head
until it engages. In doing so, check the correct positioning of the groove
in the adapter (10).
Dismantling the adapter (10)
Press the two retaining springs on the magnetic ring (19) downwards
and pull the adapter (10) off of the magnetic ring (19).
1.
Mounting the catch with freewheel mechanism (Figure ) *
IMPORTANT
If the tubular motor is to be operated with automatic end point con-
figuration and obstacle detection, then the catch (8) must be mounted
with free-wheeling action.
Slide the catch (8) onto the drive adapter (20) so that it can free-wheel
and so that it engages behind the retaining clip (7).
Free-wheeling is given if the catch (8) can be easily turned back and
forth.
* = supplied state
1.
Mounting the catch without freewheel mechanism (Figure )
Slide the catch (8) onto the drive adapter (20) so that it cannot free-
wheel and so that it engages behind the retaining clip (7).
NOTE
◆ If the catch (8) is mounted without the freewheel mechanism, then
the tubular motor will work without obstacle detection and without
automatic end point configuration.
◆ It may be necessary to mount the catch (8) without the freewheel
mechanism for very lightweight roller shutters or for roller shutters
which do not drop easily, in order to avoid premature switch-off.
