5.1 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 superrollo GW180 / GW185
is switched o.
i
Once the system has switched o, it is not
possible to directly operate the drive in the
same direction.
◆ First, run the belt winder back in the
opposite direction and remove any
possible obstacle.
◆ Then it is possible to operate the drive
in the original direction again.
Overload cut-o
The superrollo GW180 / GW185 is equipped with
an overload cut-o system.
If the drive jams in the UP ( ▲ ) direction (for example,
due to ice), the superrollo GW180 / GW185 is switched o.
◆ First, remove the cause of the overload.
◆ Then the superrollo GW180 / GW185 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.
