DKX newly developed electric valve control box, beautiful appearance, easy operation, stable performance, praised by users. Debugging do preparatory work before energizing the electrical device in accordance with operating instructions, and then follow the control box and electrical equipment electrical schematic wiring diagram, after checking over power. At this time, such as red and green GN RD are light, said electric valve in the middle position, check the valve motor phase sequence is correct knowledge, open to the press operation girl SO, open place electrical devices should stop working, this time the red light RD, Green GN Watts Valve off that valve is fully open position; operating close to the girl by SC, electrical installations should stop off place to work, then the red light off valve RD, GN green light, indicating that the valve is fully closed position. In the open procedure, RD shiny red, green GN lit; and in the closing process, GN green light flashes, red RD Always. Opening indicator debugging: electric adjustment potentiometer inside the device opening indicator located on the control box W1 and potentiometer W2, so that the opening of the tables in the electric valve is fully closed position indication is 0, the fully closed position full scale indication.
