The length of the leaf makes it possible to determine both the maximum number of cycles per hour and consecutive cycles, while the weight
makes it possible to determine the reduction percentage of the cycles and the maximum speed allowed. For example if the leaf is 5 m long
it will be possible to have 23 cycles/hour and 11 consecutive cycles. However, if the leaf weighs 350 Kg, they must be reduced to 50%,
resulting in 16 cycles/hour and 5 consecutive cycles, while the maximum speed allowed is V5: fast. The control unit has a limiting device
which prevents the risk of overheating based on the load of the motor and duration of the cycles. This device triggers when the maximum
limit is exceeded. The manoeuvre limiting device also measures the ambient temperature reducing the manoeuvre further when the temper-
ature is particularly high.
The "durability" estimate is shown in chapter 8 "Technical characteristics", which is the average useful life of the product. The value is deeply
influenced by the severity index of the manoeuvre, this being the sum of all factors that contribute to wear. To perform this estimate, all sever-
ity indexes in table 4 must be totalled, then the estimated durability in the graph must be checked with the total result.
For example, when NAKED is fitted to a gate weighing 650 Kg and 5m in length, equipped with photocells and without other stress related
elements, it obtains a severity index equal to 50% (30+10+10). From the graph the estimated durability is equal to 80,000 cycles.

Preparing the column for installation of the gearmotor

Important: the column must be sealed at the top.
Dimensions of the hole for introduction of the gearmotor: 520 x 134 mm
Note – We recommend use of a lid such as the one shown in the illustration (a): 151 mm, internal measurement.
