Product Durability; Preliminary Installation Set-Up Work - Nice Naked Sliding NKSL400 Instrucciones Y Advertencias Para La Instalación Y El Uso

3.2.1 - Product durability

The lifetime is the average economic duration of the product. The value of life-
time is strongly influenced by the intensity of the manoeuvres, i.e. the sum of all
factors that contribute to product wear (see Table 3).
To estimate the lifetime of your automation, proceed as follows:
01. Add the values of the items in Table 3 regarding the system conditions;
02. In Graph 1 from the value obtained above, trace vertical line until it inter-
sects the curve; from this point trace a horizontal line until it intersects the
line of the "manoeuvre cycles". The obtained value is the estimated lifetime
of your product.
The lifetime values specified in the graph are only obtainable if the maintenance
schedule is strictly observed (see chapter "Maintenance schedule"). The esti-
mation of lifetime is made on the basis of design calculations and the results of
tests performed on prototypes. As it is only an estimation, it does not represent
any form of guarantee on the effective lifetime of the product.
Example of durability calculation: automation of a gate with a door 4.5 m long
with a weight of 250 Kg, installed near the sea:
Table 3 shows the "severity index" for this type of installation: 10% ("Door length"),
15% ("Door weight") and 15% ("Presence of dust, sand or salt").
These indicators must be added together to obtain the overall severity index, which
is in this case 40%. With the value identified (40%), look at the horizontal axis of
Graph 1 ("severity index"), and identify the value corresponding to the number of
"manoeuvre cycles" our product will be able to perform in its lifespan, about 105,000
cycles.

A: Power line
B: Flashing light with aerial
C: Photocells
D: Key-operated selector switch
E: Fixed edges
F: Movable edges
Note 1 – power supply cable longer than 30 m may be used provided it has a larger gauge, e.g. 3x2,5mm
near the automation unit.
Note 2 – If the "BLUEBUS" cable is longer than 30 m, up to 50 m, a 2x1mm
Note 3 – A single 2x0,5mm 2 cable can be used instead of two 4x0,5mm
Note 4 – Please refer to Chapter "7.3.2 STOP Input" in situations where there is more than one edge, for information about the type of connection recom-
mended by the manufacturer.
Note 5 – special devices which enable connection even when the leaf is moving must be used to connect movable edges to sliding leaves.
CAUTION! – The cables used must be suited to the type of environment of the installation site.

These parts are positioned according to a typical standard layout. With refer-
ence to fig. 2, locate the approximate position for installation of each compo-
nent envisaged in the system. Important – Before installation, prepare the elec-
tric cables required for the system, with reference to fig. 2 and "Table 4 - Tech-
nical specifications of electric cables".
Caution – When laying the ducting for routing the electrical cables, also take
into account that due to possible deposits of water in the routing ducts, the
connection pipelines must not create condensate in the control unit, with con-
sequent damage to the electronic circuits.
