 III. Use 
 First, in accordance with the instructions to do electrical device debugging before the preparation of power, then in accordance with the control box electrical schematic wiring diagram of wiring and electrical equipment, the check is correct, power. 
 At this time, such as red and green GN RD are bright, said electric valve in the middle position, check the motor phase sequence is correct, the operation open to the press the little girl SO, opening in place of electric device should be stopped and RD red light, green light GN off that valve is fully open position; operations related to the girl by SC, off electrical devices when in place should stop working, this time off the red RD, GN green light, indicating the fully closed position. In the opening process, RD shiny red, green GN Always; and in the closing process, GN shiny green, red RD Always. 
 Opening indicator debug: adjusting electrical device opening position indicator potentiometer on the control box is located in W1 and potentiometers W2, so that the opening statement in the electric valve in the fully closed position, direction is 0, the fully closed when the full-scale indication.
