Product Duration; Product Technical Features - Nice LFAB4024 Instrucciones Y Advertencias Para La Instalación Y El Uso

Product duration

The duration and average economic life of the product. The value of duration
is strongly affected by the fatigue index of the manoeuvres performed by the
automation: i.e. the sum of all factors that contribute to wear of the product
(see Table 1).
The estimation of duration is made on the basis of the design calculations and
the test results performed on prototypes. In fact, as it is an estimate, it does not
represent any guarantee regarding the effective duration of the product.
To establish the probable duration of your automation, proceed as follows:
01. Calculate the fatigue index by adding the percentage values of the items
present in Table 1.
02. In Graph A of the value just found, trace a vertical line that crosses the
curve; from this point trace a horizontal line until the "manoeuvre cycles"
line is crossed. The value determined is the estimated duration of your
product.
Example of the duration calculation of an LFAB(...) / BFAB(...) gear
motor. Refer to Table 1 and Graph A:
1) - Panel length: 3 m
2) - Panel weight: 500 kg = fatigue index: 30%.
3) - Installation in windy areas = fatigue index: 15%.
4) - Does not have other elements of fatigue.
Total fatigue index = 45%
Estimated duration = 110.000 manoeuvre cycles
RECOMMENDATIONS: • All technical features stated make reference at a room temperature of 20°C (± 5°C). • Nice S.p.a. reserves the right to modify the
product at any time it deems necessary, however maintaining the same functionality and destination of use.
