3.2.1 - Product durability
Durability is the average economic life span of the product. The value of the life
span 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 life span of your automated device, 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 a 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 life
span 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 durability 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 repre-
sent any form of guarantee on the effective life span 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 “manoeu
-
vre cycles” our product will be able to perform in its life span, about 105,000 cycles.

F: Movable edges No.1 cable 2x0.5mm

( note 4 ) 30m ( note 5 )
Note 1
– power supply cable longer than 30 m may be used provided it has a larger gauge, e.g. 3x2.5mm 2 , and that a safety earthing system is provided
near the automation unit.
Note 2
– If the “BLUEBUS” cable is longer than 30 m, up to 50 m, a 2x1mm 2 cable is needed.
Note 3 – A single 4x0.5mm
2
cable can be used instead of two 2x0.5mm
2
cables.
Note 4 – if there is more than one edge, please refer to paragraph “9.1.2 STOP input” for the type of recommended connection.
Note 5
– special devices which enable connection even when the leaf is moving must be used to connect movable edges to sliding leaves.
WARNING! – The cables used must be suited to the type of environment of the installation site.

3.3 - Works in preparation for installation
La fig. 2 provides an example of an automation system, produced using Nice
components :
a
Key-operated selector switch
b Photocells on post
c
Photocells
d Main fixed edge (otional)
e
Main movable edge
f Rack
g
Secondary fixed edge (optional)
h Flashing light with incorporated aerial
i
Slight
l Secondary movable edge (optional)
These parts are positioned according to a typical standard layout. With refer -
ence to fig. 2, locate the approximate position for installation of each com -
ponent envisaged in the system.
Important
– Before installation, prepare the
electric cables required for the system, with reference to fig. 2 and to “ Table
4 - Technical 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 might create condensate in the control unit, with conse-
quent damage to the electronic circuits.
