线路图有主电路、控制电路、工作显示电路和开度指示电路等组成虚线框内的器件均装在电装内，其它器件装在控制箱内，电气元件见表1~4.The electric working principle of KFD type control cabinet equipped according to the type of electric valve actuator sees diagram 1~8 The circuit diagram consists of main circuit, control circuit， working display circuit and opening degree indicating circuit, etc. The elements in the box of broken line are installed in the electric fitting and other elements are installed in the control cabinet The electric elements see sheet 1～4.四、外形及外形尺寸Outline and outline dimensionKFD - G 型挂壁式控制箱外形和尺寸见图9、10KFD — C 型抽屉式控制箱外形和尺寸见图11KFD — X 型小型抽屉式控制箱外形和尺寸见图12The outline and dimension of KFD-G wall type control cabinet see diagram 9 and 10.The outline and dimension of KFD-C drawer type control cabinet see diagram 11.The outline and dimension of KFD—X small drawer type control cabinet see diagram 12.五、安装与调试 Installation and debugging1、将控制箱固定在支架上. 2、对照控制箱电气原理图、端子接线图,用电缆按对应的线号把控制箱和电动装置的端子连接起来。
3、把三相电源分别接到控制箱的L1、L2;L3、N端子上. 4、在阀门处于中间位置时，按“开”或“关”按钮，检查阀门的旋向是否与按钮一致，如不一致则调换电机电源相序 5、在阀“开”“闭”过程中,检查开度表指针是否正常 6、当阀门处于“全开"位置时，检查开度表指针是否指示在满刻度，如有误差，调整面板上的“开度微调”电位器 7、与阀门电动装置配套控制,详见阀门电动装置说明书1. Fix the control cabinet on the bracket.2. Connect the terminals on the control cabinet with those of the electric actuator by the cable as per electric schematic diagram and terminal wiring diagram of control cabinet3. Connect the three—phase power with L1, L2； L3, N terminal on the control cabinet.4. When the valve is in the middle， press on the ON or OFF button to inspect whether the rotation direction of valve accords with the button. If not, please exchange the phase sequence of power of the motor。
5. In the opening and closing course of valve, inspect whether the needle of opening degree meter is normal6. When the valve is totally open， inspect whether the needle of opening degree meter indicates to the limit scale. If there is error， adjust the potentiometer of “fine adjustment of opening degree" on the panel7. For the details for control of electric valve actuator, please see the operation instructions of electric valve actuator.图 1 KFD-C III型(配ZW型电装）Drawing 1 KFD—C III type (for ZW type electric fitting)图 2 KFD-C IV型（配JQ型电装）Drawing 2 KFD-C IV type (for JQ type electric fitting）图 3 KFD-X III型(配ZW型电装）Drawing 3 KFD-X III type (for ZW type electric fitting）图 4 KFD-X IV型（配JQ型电装)Drawing 4 KFD—X IV type （for JQ type electric fitting)Drawing 5 KFD-G III type图 5 KFD—G III型Drawing 5 KFD-G III type图 6 KFD— G IV型Drawing 6 KFD—G IV type图 7 KFD-GT III型Drawing 7 KFD-GT III type图 8 KFD-GT IV型Drawing 8 KFD-GT IV type表1 KFD-C 型电器元件表 表2 KFD-X 型电器元件表Sheet 1 Electric elements of KFD-C type Sheet 2 Electric elements of KFD-X type表3 虚线框内电器元件表(在电装上）Sheet 3 Elements sheet in the box of broken line （ on the electric fitting) 表4 KFD-G 型电器元件表Sheet 4 Elements sheet of KFD-G type图 9 KFD-G 型控制箱外型尺寸(普通型)Drawing 9 Outline dimension of KFD-G type control cabinet （common type)。
