B3S Wiring:
1,If SW is connected with GR,the valve will open and keep on,
At this time,LS.1 is closed,giving signal of opening totally.
2.If SW is connected with RD,the valve will close and keep off,
At this time,LS.2 is closed,giving signal of closing totally.

* The feedback signal is asynchronous with valve location.
    It is earlier than the location.
Feedback Loading capacity:  1) DC36V <=0.2A   2) AC220V  <=50mA

BP5 Wiring(The actuator color will be changed into Red)
1) When Red line connected with power " +", black connected with power " -":,Valve turns counterclockwise to fully open,micro switch S1 close and send singal of closing fully,the client can disconnect the motor power.
2) When Red line connected with power "-",black connected with power "+":Valve turns clockwise to fully open,micro switch S2 close and send the signal of opening fully,the client can disconnect the motor power.
3) Above circuit of driving motor can adopt triode or bridge circuit consist of field-effect transistor,whatever driving circuit must have the motor equipped with braking function.
