操控箱适用广泛。其沟(gou)通(tong)50HZ，额外(wai)作业压力为沟(gou)通(tong)电压380V的低(di)压电网体(ti)系中。

也可运(yun)(yun)用于(yu)沟通50HZ，电(dian)(dian)压(ya)500V以下电(dian)(dian)力体系作为消防水(shui)泵操控、潜污泵操控、消防风机操控、风机操控、照明配电(dian)(dian)操控等运(yun)(yun)用。

操(cao)控(kong)方(fang)法有直接(jie)操(cao)控(kong)发(fa)(fa)动，星三角降压发(fa)(fa)动操(cao)控(kong)、自(zi)耦降压发(fa)(fa)动操(cao)控(kong)、变频器发(fa)(fa)动操(cao)控(kong)、软发(fa)(fa)动操(cao)控(kong)等各种发(fa)(fa)动方(fang)法。

接通(tong)电(dian)(dian)(dian)源(yuan)，电(dian)(dian)(dian)源(yuan)指示(shi)(shi)灯(deng)(deng)亮，将(jiang)转(zhuan)换开关转(zhuan)至“主动(dong)”位(wei)(wei)置，查看操(cao)(cao)控(kong)柜（箱）所操(cao)(cao)控(kong)的电(dian)(dian)(dian)机(ji)是否按液位(wei)(wei)操(cao)(cao)控(kong)仪(yi)的指令动(dong)作(zuo)。当液位(wei)(wei)达(da)到操(cao)(cao)控(kong)液位(wei)(wei)时(shi)，对应液位(wei)(wei)指示(shi)(shi)灯(deng)(deng)发(fa)光，相应的限位(wei)(wei)操(cao)(cao)控(kong)继电(dian)(dian)(dian)器(qi)常(chang)开触点主动(dong)闭合，二次操(cao)(cao)控(kong)回路(lu)主动(dong)接通(tong)，电(dian)(dian)(dian)机(ji)起动(dong)，一起运转(zhuan)指示(shi)(shi)灯(deng)(deng)亮。当水(shui)位(wei)(wei)达(da)到停止(zhi)水(shui)位(wei)(wei)时(shi)，对应的指示(shi)(shi)灯(deng)(deng)发(fa)光，液位(wei)(wei)测(ce)控(kong)仪(yi)的对应限位(wei)(wei)操(cao)(cao)控(kong)继电(dian)(dian)(dian)器(qi)常(chang)闭触点断(duan)开，二次操(cao)(cao)控(kong)回路(lu)开路(lu)，电(dian)(dian)(dian)机(ji)停止(zhi)工(gong)作(zuo)，运转(zhuan)指示(shi)(shi)灯(deng)(deng)平息(xi)。
