06. On the table A below, select the box corresponding to the intersec -
tion between the line with the Ed value and the column with the K
value. The box contains the maximum possible number of cycles per
day (e.g. Ed = 2800 and K= 105; cycles per day ≈ 22).
If the number obtained is too low for the envisaged use or is located in the
“area not recommended for use”, the use of 2 or more photovoltaic panels
may be considered, or the use of a photovoltaic panel with a higher power.
Contact the Nice technical assistance service for further information.
The method described enables the calculation of the maximum possible
number of cycles
per day
that can be completed by the automation while
running on solar power. The calculated value is considered an average
value and the same for all days of the week. Considering the presence of
the battery, which acts as an energy “storage depot”, and the fact that the
battery enables automation autonomy also for long periods of bad weather
(when the photovoltaic panel produces very little energy) it may be possible
to exceed the calculated maximum possible number of cycles per day, pro -
vided that the average of 10-15 days remains within the envisaged limits.
Table B below specifies the maximum possible number of cycles,
according to the manoeuvre’s severity index (K), using exclusively the
energy stored by the battery. It is considered that initially the battery is
completely charged (e.g. after a prolonged period of good weather or
recharging via the optional PCB power supply unit) and that the manoeu -
vres are performed within a period of 30 days.
When the battery runs out of the stored energy, the led starts to indicate
the battery low signal by flashing briefly every 5 seconds, accompanied
by a “beep”.

10.3 - ADDING OR REMOVING DEVICES
An automation using WG2S enables devices to be added or removed at
any time.
Caution! – Do not add devices before ensuring that they are fully
compatible with WG2S; for further details, contact the Nice techni -
cal assistance.
10.3.1 - ECSBus
ECSBus is a system that enables connections of ECSBus devices using
just two wires, which convey both electrical power and communication
signals. All devices are connected in parallel on the same 2 wires of the
ECSBus; each device is recognised individually as it is assigned a unique
address during installation.
Photocells and other devices using this system can be connected to
ECSBus, such as safety devices, control buttons, indicator lights etc. For
information on ECSBus devices, refer to the Mhouse catalogue or visit the
website www.niceforyou.com .
A special learning phase enables the control unit to recognise all con-
nected devices individually, and enables precise diagnostics procedures.
For this reason, each time a device connected to ECSBus is added or
removed, the learning phase must be performed on the control unit; see
paragraph 10.3.3 “Learning other devices”.
10.3.2 - STOP Input
STOP is the input that causes immediate shutdown of the movement (fol -
lowed by a brief inversion of the manoeuvre). This input can be connected
to devices with contact types Normally Open (NO, as in the case of the
KS100 selector switch), Normally Closed (NC) or devices with a constant
resistance of 8.2 kΩ, such as sensitive edges.
When set accordingly, more than one device can be connected to the
STOP input, also different from one another; see Table 7 .
Note 1. The NO and NC combination can be obtained by placing the
two contacts in parallel, and placing an 8.2kΩ resistance in series with
the NC contact (it is, therefore, possible to combine 3 devices: NA, NC
and 8,2k
Ω
).
Note 2. Any number of NO devices can be connected to each other in
parallel.
Note 3. Any number of NC devices can be connected to each other in
series.
Note 4. Only two devices with an 8.2 kΩ constant resistance output can
be connected in parallel; multiple devices must be connected “in cas -
cade” with a single 8.2 kΩ termination resistance.

TABLE 7
2nd
device type:
Caution! – If the STOP input is used to connect devices with safety
functions, only the devices with 8.2 kΩ constant resistance output
will guarantee the fail-safe category 3.
As with the ECSBus, the control unit recognises the type of device con -
nected to the STOP input during the learning phase; subsequently the
control unit gives a STOP command when it detects a variation with
respect to the learned state.
10.3.3 - Recognition of other devices
The learning operation of the devices connected to the ECSBus and
STOP input is usually carried out during the installation phase; if devices
are added or removed the learning operation can be carried out again as
follows:
01.
Press and hold key P2
[B]
on the control unit for at least three sec-
onds ( fig. 41 ), then release the key.
02. Wait a few seconds for the control unit to complete the device learn -
ing phase.
03.
At the end of the learning the LED P2
[A]
(
fig. 41
) should switch off.
If the LED P2 flashes it means there is an error; see paragraph 10.5
“Troubleshooting”.
04.
After having added or removed a device the automation test must be
carried out again as specified in paragraph 8.1 “Testing”.
