9.9 - SPECIFICATIONS

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 sui-
table arrangements, multiple devices – even of different type – (read Table 11) can be connected to the Stop input.
TABLE 11
NO
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.
During memorisation in Mode 1, it is normal for it to last maximum 10 seconds.
During memorisation in Mode 2, it is normal for it to last maximum 10 seconds.

(Note 4)
In series
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.
