Product description
ELEVO is a gearmotor designed for the automation of sectional and overhead doors.
ELEVO operates using electric power. In the event of a power failure, the gearmotor can be released in order to 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 doors within the limits shown in
tables 1
,
2
and
3
.

The measurements in
table 2
are to be taken as a guideline and are for general estimate purposes only. The effective suitability of ELEVO for
automating a specific door depends on the degree of door leaf balancing, guide friction and other aspects, 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 9 (“Technical specifications”); also, to calculate the number of cycles/hour and consecutive
cycles, the data in
tables 3
and
4
.must be taken into account.

The height of the door enables the maximum number of cycles per hour and consecutive cycles to be calculated, while the force required
to move the door enables the percentage of cycle reduction to be determined; for example, if the leaf height is 2.2 m, this would enable 12
cycles per hour and 6 consecutive cycles, but if a force of 250 N is required, these would have to be reduced to 70%, resulting therefore in 8
cycles per hour and around 4 consecutive cycles.
To avoid overheating, the control unit has a limiter that is based on the motor operation and duration of cycles, and trips when the maximum
limit is exceeded.
N.B.:
1 kg = 9.81 N, for example, 500 N = 51 kg
