Anemometer feeding meter relay energizes control relay for antenna-tower hoist motor, to lower tower au-tomatically when wind exceeds preset safe speed and raise it again when wind drops well below danger level. When only K1 is energized, motor rotates in tower-lowering direction.When K1 and motor-reversing relay K2 are both energized, motor reverses and raises tower.-J.Bernstein, The Tower-Guard System, QST 1974,p 25-28
