Electrical Connections - Nice Volo ST Instrucciones Y Advertencias Para El Instalador

2.1) Electrical connections

The Volo ST sensor is connected to the control units and motors by
means of 2 wires through which run the power supply as well as the con-
trol signals (blue wire). Up to 5 parallel control units or motors can be
connected to each sensor as shown in figure 10. Observe the polarity,
connecting wires of the same colour or the same control unit terminals.
The sensors are equipped with an input (grey wire) that deactivates the
sun reading (the wind protection is always active); a simple switch can be

!
Volo ST climatic sensors can only be connected to motors and control units which have been designed for this purpose.
Incorrect connection or use may cause serious damage to the sensor.
3) Testing
To make sure that the sensor has been installed properly follow the steps
listed below. The following description refers to the use of a sensor with
3.1) Connection testing
1. Make sure that the sensor is powered by the motor (24±5 Vdc on the
blue wire terminals).
2. Disconnect the power to the motor and reconnect after a few seconds
3.2) Wind sensor testing
1. Position the awning at an intermediate point between the open and
closed positions.
2. Adjust the wind trimmer to the minimum value.
3. Rotate the anemometer (using a hair dryer if need be) increasing the rota-
tion speed; once the wind threshold has been exceeded for 3 seconds,
3.3) Sun sensor testing
1. If the motor is in the condition described in point 4 of above, the pow-
er to the motor must be disconnected and then reconnected and the
awning positioned at an intermediate point between the open and
closed positions
2. Adjust the sun trimmer to the minimum value.
4) Adjustments
Rotate the trimmers according to the values shown in Fig. 11 in order to
adjust the "sun" and "wind" triggering thresholds.
• Wind: the anemometer measures the speed of the wind in real time.
When the speed exceeds the threshold set using the trimmer for at lea-
st 3 seconds, the red led will switch on and the sensor will send to the
control unit or the motor an ascent manoeuvre command (▲).
• Sun: the "sun" sensor measures the intensity of solar radiation in real
time. When the intensity of the light exceeds the threshold set using the
trimmer, the green led will switch on and the sensor will send a com-
mand to the control unit or the motor so that after 2 minutes the con-
trol unit or the motor will command a descent manoeuvre (▼).

The threshold that may have been programmed on the con-
trol unit or motor is of no importance.
used to operate this function that deactivates the sun reading when
closed. The automatism can also be enabled and disabled by means of
the ERGO4 and PLANO4 transmitters. Make sure the fixing bracket cov-
er is properly closed once the wiring has been performed.
a motor for awning automation; however, this procedure can also be
used for the other applications.
(if necessary, place the two terminals with the blue wires in short cir-
cuit for a few seconds); check that the led gives a red and a green
flash when switched on.
the red led lights and the sensor sends a signal to the motor which
activates a manoeuvre in the same direction as the ▲ button on the
remote control.
4. The awning will roll up completely and usually for 1 minute no other
commands can be given.
3. If the light is not strong enough to trigger the sun threshold, the sensor
must be illuminated with a sufficiently intense light source (lamp) to cause
the green led to light; after the sun threshold has been exceeded the sen-
sor sends a command that, after approximately 2 minutes, starts a
manoeuvre in the same direction as the ▼ button on the remote control.
