State
Close : Contact ON Open : Contact OFF
Reading method of Di signal (State)
Di signal “State” shows “Open” and “Close” of the each switch contact. However, Main and Aux. winch two-blocking detection switch (circuit) contacted with the series circuit. Therefore when either switch detects the overwound and the switch contact becomes “Open”, then, both contacts become “Open”. In a word, State of Di5 changes two signals at the same time. These functions are not provided in other Ai and Pi, etc.
