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 4 .
To estimate the life span of your automated device, proceed as follows:
01. Add the values of the items in Table 4 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 .
Sample durability calculation: automation of a gate with a door 10 m long with a
weight of 150 Kg, installed near the sea:
Table 4 shows the "severity index" for this type of installation: 15% (length of gate), 30%
(weight of gate) and 10% (ambient temperature > 40°C or < 0°C or humidity > 80%").
These indicators must be added together to obtain the overall severity index, which is
in this case 55%. With the value identified (55%), 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 life span, about 180,000 cycles.

3.3 - Works in preparation for installation

fig. 2 provides an example of an automation system, produced using Nice
components:
1 Key switch
2 FT210B receiver
3 Photocells
4 FT210B transmitter
5 Main mobile edge
6 Open stop bracket
7 Rack
8 Flasher with integral antenna
9 RUN
10 Closed stop bracket
11 Secondary mobile edge (optional)
12 Transmitter
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
5% electric cables required for the system, with reference to fig. 2 and to "Table
5 - Technical specifications of electric cables" .
10%
Caution - When laying the ducting for routing the electrical cables, also take
15% 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-
20%
quent damage to the electronic circuits .
