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
t
) direction, the
belt will stop moving and the RolloTron Swivel Winder
Standard DuoFern is switched off.
i
Once the system has switched off, it is not
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.
Overload cut-off
The RolloTron Swivel Winder Standard DuoFern is
equipped with an overload cut-off system.
If the drive jams in the UP (
▲
▲
) direction (for example, due
to ice), the RolloTron Swivel Winder Standard DuoFern
is switched off.
◆
First, remove the cause of the overload.
◆
Once the cause has been rectified, the RolloTron
Swivel Winder Standard DuoFern is fully operational
again in both directions.
i
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.
