6.1 Description of the safety functions

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 RolloTron Basic DuoFern
1200 is switched off.
Once the system has switched off, it is not
i
possible to directly operate the drive in the
same direction.
◆ First, run the belt winder back in the op-
posite direction and remove any possible
obstacle.
◆ Then it is possible to operate the drive in
the original direction again.
There is a risk of injury if the obstacle detection is
not working.
◆ The belt must be wound on as evenly as possible to
ensure safe and correct functioning of the obstacle
detection function.
◆ Please ensure that the belt winds as straight and
evenly as possible into the device during its subse-
quent cycle after the obstacle detection system has
triggered.
Overload cut-off
The RolloTron Basic DuoFern 1200 is equipped with
an overload cut-off system.
If the drive jams in the UP ( ▲ ) direction (for example, due
to ice), the RolloTron Basic DuoFern 1200 is switched off.
◆ First, remove the cause of the overload.
◆ Once the cause has been rectified, the RolloTron
Basic DuoFern 1200 is fully operational again in both
directions.
