move the door manually.

Operating limits

Chapter 16 ("Technical specifications") 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.
Model:
ROLLS 700
ROLLS 1200
The effective suitability of ROLLS for automating a specific 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" specified in section 16 ("Technical specifications"); 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
