6. Functional description
The RADEMACHER RolloTube S-line Zip DuoFern radio
tubular motors are used for raising and lowering
screens in Zip systems.
The RolloTube S-line Zip DuoFern tubular motors are
self-learning motors. The end positions are automati-
cally learned during the first run cycles. This elimi-
nates 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 55.
The compact design and self-learning motor en-
sure a quick and easy installation.
The RolloTube S-line Zip DuoFern impresses
in daily operation with blockage detection in both
directions of travel and obstacle detection, ensuring
maximum safety and gentle operation.
Use in the DuoFern network
As soon as you integrate your RolloTube S-Line Zip
DuoFern into a DuoFern radio network, you can set
and make use of many different automatic functions
using DuoFern controllers such as the HomePilot®.
DuoFern controllers and transmitters must be con-
nected to the DuoFern network.

6.1 Blockage detection function
Function of the blockage detection
when raising the screen
The tubular motor stops and automatically relieves
the strain on the screen by shifting briefly in the
opposite direction (reversing) in the event that the
screen is blocked by an obstacle while it is being
raised.
Requirements for correct blockage detection:
◆
The screen must move easily and freely.
If the motor detects a blockage due to strong wind,
it will reverse first. After a few seconds, another
attempt is made to raise the screen. The number of
attempts can be configured via the HomePilot®.
i
In conjunction with an environmental
sensor/etc., the motor can react to a
wind command and raise the screen
without detecting a blockage.
Moving a blocked (e.g. iced-up/jammed) screen
can result in overloading and damage to the
tubular motor and Zip system.
◆
Do not move the iced-up/jammed screen and
rectify the fault or remove the obstacle.
