6. Functional description

Only use RADEMACHER RolloTube S-line DuoFern
tubular motors for opening and closing roller shut-
ters and awnings.
The RolloTube S-line DuoFern tubular motors are
self-learning motors with a smooth stop at both end
positions. The end positions for the smooth stop are
automatically learned during the first run cycles.
This eliminates the need to set the end points or a
teach-in run.
However of course, the end points can also be set
manually see page 62.
The lower end point must be set manually when
using it as an awning drive, see page 62.
The compact design and self-learning smooth stop
ensure a quick and easy installation.
The RolloTube S-line DuoFern impresses in daily
operation with blockage detection in both direc-
tions of travel, ensuring maximum safety and gentle
operation.
The roller shutter must be equipped
i
with stoppers or an end rail in order to
use the RolloTube S-line DuoFern in self-
learning mode, see page 55 / 56.
Use in the DuoFern network
As soon as you integrate your RolloTube S-Line
DuoFern into a DuoFern radio network, you can
set and make use of many different automatic
functions using DuoFern controllers such as the
HomePilot® or central operating unit.
DuoFern controllers and transmitters must be con-
nected to the DuoFern network.

6.1 Blockage detection function

The tubular motor stops and automatically shifts
briefly in the opposite direction (reversing), in the
event that the roller shutter is blocked by an obstacle
in one of the two directions of travel (e.g. if a roller
shutter is iced-up/jammed).
Moving a blocked (e.g. iced-up/jammed) roller
shutter may overload and damage the tubular
motor and roller shutter system.
◆ Do not move the iced-up/jammed roller shutter
and rectify the fault or remove the obstacle.
Overview of functions:
◆ Self-learning mode with a smooth stop at both
end positions, see page 62.
◆ Torque monitoring
◆ Blockage detection in both directions of travel,
including reversing function
◆ Obstacle detection include reversing function
◆ Shutter length compensation
◆ Quick and easy installation thanks to the short
design
◆ Either one or both end points can be set manu-
ally as required. Also in combination with the
self-learning mode.
◆ Jog mode when using a roller shutter button
◆ Operation using a roller shutter switch
◆ Controller with a 1-pole button
◆ Fly screen door protection
◆ DuoFern radio code for activating registering
mode in combination with the HomePilot® or
DuoFern manual central operating unit.
Requirements for correct blockage detection:
◆ The roller shutter must always run vertically, eas-
ily and freely in the guide rails of the window.
