Manual   brake

keep   pressing the button 5s unload completely,and then recover by pressing it for   another 5s

Tune the switch   on the panel to"BRAKE position",three-phase AC short cricuit,turn   to "RUN" position to run.

Brake by   overcurrent

45A（factory   default,0-54A settable）it dumps load   completely when overcurrent,and will recover after 10mins automatically

Brake by   over rotational speed(optional)

300RPM（factory   default，0~1499RPM settable）unload completely when   reached the set rotational speed ,and recover automatically after 10mins

Brake by   over wind speed(optional)

18m/s（0~30m/settable），it dumps   load completely when reached the set wind speed ,and recover automatically   after 10mins
