Fixed safety braking for wind turbine:
The wind turbine can be braked in a fixed position for several reasons:
Automatic safety braking:
This is a function designed to increase the safety of
the equipment and to lessen wear suffered by the system's mechanical elements,
and it works through using an internal counter by which the wind turbine
reduces its turning speed automatically when, over an uninterrupted 120 minute
period, at least 1500 braking impulses have been affected. When this occurs, the
system deduces that the battery is completely charged and the wind turbine is
not freed from the fixed braked mode until the voltage has lowered to under
12.5v - 25v - 50v.
When this situation arises, and the automatic braking is active, the status
message appears at the end of the second line on the screen, as in the following
