吴忠三相 380V控制箱

▼剖面分解图/Cross section and parts list：

▼产品特点/Detailed Introduction：

1、每一规格功率的水泵配置同一功率的自动控制箱;

2、控制箱置于无直经日晒雨游、通风良好的环境，避免强烈震动;

3、无空气开关的规枯品科，需在电源输入端外接空气开关(或三相闸刀开关)作隔离开关及短路保护:

4、 保险丝选定:熔断电流=电机额定电流X(1.5-2);

5、按机内及说明书的两图，控设并接好三相电源线，电机线和水位电极线。水位电

校线对线经要求不严、主要考虑架空强度。

6.各电级线、电极塔（池）井壁之间不得短路:

7、水源克足，水位不会降至大泵进水口的场合，可以不装“并电极”，但必须将主线路板上部的微型拨动开关拨至右边(或在接线端子上将“井极”和“回路”用导线短接)。反之则应拨至左边:

8.开机最应行细检查、确认安装提线正确无误，三相电源电压正常，无缺相现象，符合使用最件、方可开机。

1.Each pumnp with rated horsepower should match the automatie controt box with the same horsepower.

2.Do not expose the control box to the strong sunlight or get it wet by tain, Put it in a well-ventilated place, and avoiding strong shock.

3.The live wire of three-phase power should go through on-off switch, the zero wire can go through directly.

4.Fuse requirement：fusing current = rated current X (l.5~2）

5.The water-level control of headwaters and water tower needa only an electrode conducting wire and a return conducting wire. The upper and lower limits of the water level can be differentiated by special "level divider". One side of it has a conducting wire, which should be connected with the terminal ot "well electrode" or "tower electrode"; the other side has two conducting wires. of which the short one is the water-level upper limit conductng wire, while the long wire is the water-level lowor limit conducting wire.Both conducting wires can be connected with electrode detector respectively and be put at the required water levels. If the electrode cannot reach the required depth, the conducting wire can be lengthened. The return electrode must be placed under upper and lower electrodes.

6.Short circuit should be avoided between various conducting wires, electrode, and the wall of the well or tank.

7."Well Electrode" could not be installed if water is sufficient, and the water level will never be lowered to the intake of the pump, but the micro switches on the upper part of the main circuit board should be turned to "right"(or connect terminal "well electrode" with "return electrode"),otherwise the switches should be turned to "left".

8.Check the connection of wires and make sure the a installation, the three phase power voltage is right, and no phase vacancy. then turn on it.
