CONTROL UNIT OPERATION DIAGRAM
Looking at our practical case explained above, our Relays, past a concrete Tr previously set up in the control unit, are set to 1.
Once the wind speed reaches MAX2 = 10 km/h, our Relay 1, after a Td, is deactivated.
Arrived to MAX3 = 20 km/h, and passed again a Td, our Relay 2 will be deactivated.
When the speed will go down again under MAX2, our Relay will activate again after a predetermined Tr. The same thing happens with the
Relay 1, when the wind speed decreases below MAX1 during a Tr period.
