2.1) Operating limits
Chapter 8 "Technical Characteristics" provides the data needed to determine whether the products of the SPIN line are suitable for the intend-
ed application.
The structural characteristics of the SPIN products make it suitable for use on sectional and overhead doors within the limits shown in Tables
2, 3 and 4.

The measurements in table 2 are guideline only and can be used as a general estimate only. The effective suitability of SPIN 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 "rated torque" specified in chapter "8 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 a calculation of the maximum number of cycles per hour and consecutive cycles, while the force required to
move the door enables a calculation of the percentage of cycle reduction; 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 250N 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.
Note: 1Kg = 9.81N, for example, 500N = 51Kg
