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 GW250 / GW255

is switched o.

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 GW250 / GW255 is equipped with an

overload cut-o system.

If the drive jams in the UP ( ▲ ) direction (for example, due

to ice), the superrollo GW250 / GW255 is switched o.

◆ First remove the cause of the overload.

◆ Then the superrollo GW250 / GW255 is fully

operational again in both directions.

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

subsequent cycle after the obstacle detection

system has triggered.
