9. Brief description
Soft-start / Soft-stop
The RolloTron Comfort DuoFern is equipped with a Soft-
start / Soft-stop function. Gentle starting and stopping
serves to protect the belt winder mechanics and the belt.
Obstacle detection
The movement of the belt is monitored. If the roller shutters
hit an obstacle in the DOWN ( t ) direction, the belt will stop
moving and the belt winder is switched off.
Once the system has switched off, it is no longer
possible to directly operate the drive in the same
direction.
Run the belt winder back in the opposite direction and
remove any possible obstacle. Subsequently it is possible
to operate the drive in the original direction again.
NOTE
Please ensure that the belt winds evenly during its
subsequent cycle after the obstacle detection system has
triggered.
Overload cut-off
The RolloTron Comfort DuoFern is equipped with an
overload cut-off system.
If the drive jams in the UP ( ▲ ) cycle (for example, due to
ice), the belt winder will also switch off. Once the cause
for the overload has been rectified, the drive will be fully
operational in both directions.
