Note: if the severity index exceeds 100%, this means that the conditions are beyond the acceptable limits; a larger model is therefore advised.

Table 4: durability estimate in relation to the manoeuvre severity index
Severity index %
Durability in cycles
The length of the leaf makes it possible to determine both the maxi-
mum 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, for RB 500 if
the leaf is 5 m long it will be possible to have 25 cycles/hour and 13
consecutive cycles. However, if the leaf weighs 500 Kg, they must be
reduced to 75%, resulting in 15 cycles/hour and 7 consecutive cycles,
while the maximum speed allowed is V4: 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 temperature is particularly high.
The “durability” estimate is shown in chapter 8 “Technical characteris-
tics”, 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 RB 500 is fitted to a gate weighing 360 Kg and 4m
in length, equipped with photocells and without other stress related
elements, it obtains a severity index equal to 55% (30+10+15). From
the graph the estimated durability is equal to 70,000 cycles.
