Functional description

RADEMACHER RolloTube X-line series of tubular motors are designed for opening and
closing roller shutters and awnings.
RolloTube X-line tubular motors are equipped with the new Safe-Drive system for position
detection, torque monitoring and obstacle detection. The drive's compact design and fully
automatic end point configuration ensures for straightforward and convenient installation.
The RolloTube X-line tubular motor impresses in daily operation with automatic roller shut-
ter compensation as well as the blockage and obstacle detection system (with reversing
function), ensuring maximum safety and gentle operation.
Tubular motor functions:
◆ Commissioning with a single run command. Self-learning motor with fully automatic
end point configuration.
◆ Safe-Drive method for precise positioning, torque monitoring and obstacle detection.
◆ Blockage and obstacle detection including reversing function.
◆ Obstacle detection can be arbitrarily configured thanks to the new snap-in FlexiClick
system.
◆ Maintenance free end points thanks to automatic shutter length compensation system.
◆ Quick and easy installation thanks to the new shorter design.
◆ Optionally available: Universal RT ConfigTool for individual configuration of the
motor parameters.

Blockage detection function

The tubular motor stops and automatically shifts into the opposite
direction (reversing) in the event that an obstacle is detected while
opening (e.g. if a roller shutter is iced-up).
i

Obstacle detection function

The tubular motor stops and automatically shifts briefly in the opposite
direction (reversing) in the event that the roller shutter hits an obstacle
while closing.
NOTE
The reversing mechanism after obstacle detection can be switched
on / off if necessary.
Requirements for correct obstacle detection:
◆ The catch with freewheel mechanism must be mounted (see Fig. 4.a; page 53).
◆ The roller shutter must be mounted to the rotating union with the fastening springs
or with the fixed shaft connector.
◆ Roller shutters must always run vertically in the guide rails of the window.

Function of the shutter length compensation system

The shutter length compensation system is active subsequent to every
automatic learning process for the upper end point. Afterwards, the
tubular motor no longer runs fully against the upper end point in order
to protect the roller shutters and the end points.
For example, seized roller shutters can cause the automatically learned
end points and runs to be changed over a period of time. In order to
compensate for this, the tubular motor periodically runs automatically
to the upper and lower end points (the cycle for this is configured at
the factory).
KNX functions
◆ KNX bus connection via twisted pair cable.
◆ Up / Stop / Down control.
◆ Precise position start-up and genuine motor shaft position feedback.
◆ Objects „obstacle detected" and „blockage detected".
◆ Control via internal / external automatic function (e.g. temperature).
◆ 8-fold scenario control.
◆ Various alarms and barrier objects.
NOTE
All available KNX parameters and settings, see page 69.
NOTE
Do not move iced-up roller shutters and rectify the fault or remove the obstacle.
Tubular motors with obstacle detection should not be used in multi-part
systems that are operated with a drive via a winding shaft, because ob-
stacle detection will be delayed or may not trigger at all in such systems.
NOTE
◆ The roller shutter compensation system operates automatically during normal opera-
tion, so that generally you will not notice it.
◆ If the upper end point is manually configured, then the roller shutter compensation
system is inactive.
