2. Product description
ROLLS is a gearmotor designed for the automation of sectional and overhead doors.
ROLLS operates using electric power, in the event of a power failure from the electrical network, it is possible to release the gearmotor and
move the door manually.
2.1 - Operating limits
Chapter 16 (“Technical specications”) provides the data needed to determine whether the product is suitable for the intended application.
Its structural characteristics make it suitable for use on sectional and overhead doors within the limits shown in table 1.

The effective suitability of ROLLS for automating a specic door depends on the degree of door leaf balancing, guide friction and other as-
pects, including occasional phenomena such as wind pressure or the presence of ice, which could obstruct leaf movement.
To establish effective conditions, the force required to move the leaf throughout its stroke must be measured to ensure that this value does not
exceed the “nominal torque” specied in section 16 (“Technical specications”); also, to avoid overheating, the control unit provides a limiter
based on engine effort and cycle duration, that intervenes when
the maximum limit is exceeded.
N.B.: 1 kg = 9.81 N, for example, 500 N = 51 kg
