Fit the blade by means of 2 screws M10 and 2 self-locking
nuts (tightening torque 70 Nm).

5.10 Wind sensor (optional)
NOTE
Place the wind sensor in correspondence of the most critical area.
The Breeze Fan with wind sensor is able to manage the machine also if the wind is too strong.
The Breezefan with wind sensor has to work with a specific drive: the SK520 Inverter.
The wind sensor has to be connected like indicated in the pictures below (see Fig.24); pay attention that the wind sensor
cable is at low voltage (15Vdc) and have to be:
•
keep away from high voltage (230Vac or more) or switching signal
•
lay out on a standalone tube
•
shielded cable.
At the start up (switch on the main power supply and the “switch On” the start command) the Breeze Fan checks the wind
speed, before to start the blades rotation. Only if the wind is not too strong, the Breeze Fan starts to work.
If the wind speed is not so strong, the Breeze Fan starts the rotation of the blades (after the Starting Time more or less 1
minute). This time is useful to be sure that the Breeze Fan could work in the correct way and with the right wind condition.
When the Breeze Fan is working and the average
wind becomes too strong the machine will be switch off; before the
Breeze Fan starts to rotate it needs that the average
wind speed becomes lower (inside the working wind range).
If the Wind sensor has disconnected or the wind sensor cable has cut off during the normal working, the Breeze Fan stops
to rotate and goes to the shutdown state. In this state (when the wind sensor disconnection occurs), the Breeze Fan tries
to restart itself for five times; after that, if the problem is continuously present, it goes to a permanently off state. This fault
only occurs when the sensor is disconnected. When the Breeze Fan is in the off state, in order to get it operative again, it
is necessary to:
•
connect the wind sensor (or check the continuity of the wires) or change the wind sensor;
•
switch off the main power supply and wait some seconds (3 seconds are enough);
•
switch on the main power supply.
