9.9.1 - ECSbus system

ECSbus is a system that allows for connecting ECSbus devices using just two wires, which convey both electricity and communication signals. All
the devices are connected in parallel on the two ECSbus wires; each device is recognised individually by the control unit, thanks to an unambiguous
address assigned to each device during installation.
Photocells and other devices adopting this system can be connected to the ECSbus, such as safety devices, control buttons, indicator lights etc. For
information on ECSbus devices, consult the Nice Home range product catalogue or visit the website www.niceforyou.com
Through a recognition procedure the control unit recognises one-by-one all the devices connected and this enables it to detect with extreme precision
all possible anomalies during the automation's normal operation. For this reason, whenever a device connected to the ECSbus is added or removed, it
is necessary to repeat the recognition procedure for these additional devices (Par. 9.2.1).

9.9.2 - Stop input

The Stop input causes the immediate stoppage and a brief inversion of the manoeuvre; both devices with normally open (NO) contacts and devices
with normally closed (NC) contacts can be connected to this input, as well as devices with 8.2 kΩ constant resistance (e.g. sensitive edges). With suit-
able arrangements, multiple devices – even of different type – (read Table 11) can be connected to the Stop input.

NO In parallel (Note 2)
NC (Note 1)
8.2 kΩ In parallel
CAUTION! – If the Stop input is used to connect devices with safety functions, only the devices with 8.2 kΩ constant resistance output
guarantee Category 3 safety against faults.
Similarly to the ECSbus, the control unit recognises the type of device connected to the Stop input when the recognition procedure is carried out.
Subsequently, the system triggers a STOP when any variation occurs with respect to the recognised status.

9.9.3 - Product durability

Durability is the average economic lifespan of the product. The durability value is strongly influenced by the degree of severity of the manoeuvres, in
other words, the sum of all factors that contribute to product wear (Table 10). To estimate the life span of your automated device, proceed as follows:
01. Add up all the values of the entries in Table 12;
02. In Graph 1, from the value obtained above, trace a vertical line until it intersects the curve; from this point trace a horizontal line until it intersects
the line of the "manoeuvre cycles". The value obtained is the estimated lifetime of your product.
The durability values specified in the graph are only obtainable if the maintenance schedule is strictly observed (Chapter 7). The lifetime is estimated on
the basis of design calculations and the results of tests performed on prototypes. Being only an estimate, it does not constitute any form of guarantee
on the actual lifespan of the product.
Example of durability calculation: automation of a gate with a door 1.5 m long with a weight of 220 kg, installed in a windy area. Table 1 shows the
"severity indices" for this type of installation: 10% ("Door length"), 20% ("Door weight") and 15% ("Installation in windy area"). These indicators must be
added together to obtain the overall severity index, which in this case is 45%.
With the value identified (45%), look at the horizontal axis of Graph 2 ("severity index"), and identify the value corresponding to the number of "manoeu-
vre cycles" our product will be able to perform in its lifespan, about 55,000 cycles.

Note 1: the NO and NC combination is possible by wiring the 2 contacts in parallel,
while making sure that a 8.2 kΩ resistor is connected in series with the NC contact
(therefore, it is also possible to combine 3 devices: NO, NC and 8.2 kΩ).
Note 2: multiple NO devices can be connected in parallel to each other without any
quantity limit.
Note 3: multiple NC devices can be connected in series to each other without any
quantity limit.
Note 4: only 2 devices with 8.2 kΩ constant resistance output can be connected in
parallel; if required, multiple devices must be connected in "cascade" mode with a
single 8.2 kΩ termination resistance.
