Reading method of Di signal (State)
Di signal “State” shows “Open” and “Close” of the each switch contact.
However, Main and Aux. winch twoblocking 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.
