2、使用条(tiao)件：(1)周围高气(qi)温(wen)(wen)≤+40℃，≥-5℃，且24h平均(jun)温(wen)(wen)度(du)不(bu)超过+35℃；(2)安装地点海拔不(bu)超过200m；(3)空气(qi)月平均(jun)大湿(shi)度(du)百分之≤90（平均(jun)气(qi)温(wen)(wen)25℃时）；(4)周围空气(qi)无爆炸危险的介(jie)质(zhi)，且介(jie)质(zhi)中无足以腐(fu)蚀金属和(he)破坏绝缘的气(qi)体及(ji)导电尘埃（污染等级(ji)3级(ji)）。

3、种类：本型控(kong)制器有(you)一控(kong)一、二控(kong)二（一用(yong)一备）、一控(kong)三（二用(yong)一备）三种。

直接(jie)(jie)启(qi)动(dong)控(kong)(kong)制柜（工频启(qi)动(dong)控(kong)(kong)制柜）控(kong)(kong)制回路(lu)中，既设(she)自动(dong)控(kong)(kong)制亦有手动(dong)控(kong)(kong)制，还具备过压、过流、欠压、缺相保护及事故报苦功能，使用前，须按电气原(yuan)理图(tu)复(fu)核后接(jie)(jie)线，按照电动(dong)机(ji)实际(ji)要求调整相应元件设(she)定值，然(ran)后起(qi)动(dong)。

1、自动(dong)(dong)(dong)(dong)操作(zuo)：接通(tong)电(dian)(dian)源，电(dian)(dian)源指示(shi)(shi)灯(deng)亮，将转换开(kai)(kai)关转至“自动(dong)(dong)(dong)(dong)”位(wei)(wei)置(zhi)，检(jian)查控(kong)(kong)(kong)(kong)制柜（箱）所控(kong)(kong)(kong)(kong)制的电(dian)(dian)机是(shi)否按(an)液位(wei)(wei)控(kong)(kong)(kong)(kong)制仪的指令动(dong)(dong)(dong)(dong)作(zuo)。当液位(wei)(wei)达(da)到(dao)(dao)控(kong)(kong)(kong)(kong)制液位(wei)(wei)时，对(dui)应 液位(wei)(wei)指示(shi)(shi)灯(deng)发光，相应的限位(wei)(wei)控(kong)(kong)(kong)(kong)制继电(dian)(dian)器常开(kai)(kai)触点(dian)自动(dong)(dong)(dong)(dong)闭合，二次控(kong)(kong)(kong)(kong)制回(hui)路(lu)(lu)自动(dong)(dong)(dong)(dong)接通(tong)，电(dian)(dian)机起动(dong)(dong)(dong)(dong)，同(tong)时运行指示(shi)(shi)灯(deng)亮。当水位(wei)(wei)达(da)到(dao)(dao)停止水位(wei)(wei)时，对(dui)应的指示(shi)(shi)灯(deng)发光， 液位(wei)(wei)测控(kong)(kong)(kong)(kong)仪的对(dui)应限位(wei)(wei)控(kong)(kong)(kong)(kong)制继电(dian)(dian)器常闭触点(dian)断(duan)开(kai)(kai)，二次控(kong)(kong)(kong)(kong)制回(hui)路(lu)(lu)开(kai)(kai)路(lu)(lu)，电(dian)(dian)机停止工作(zuo)，运行指示(shi)(shi)灯(deng)熄灭。

2、手(shou)动(dong)操(cao)作(zuo)：接通电(dian)源，电(dian)源指(zhi)示灯亮(liang)，将转(zhuan)(zhuan)(zhuan)换开(kai)关转(zhuan)(zhuan)(zhuan)至“手(shou)动(dong)”位置 ，按下起动(dong)按钮，电(dian)机(ji)开(kai)始(shi)运(yun)转(zhuan)(zhuan)(zhuan)，运(yun)行指(zhi)示灯亮(liang)，按下”停止”按钮，电(dian)机(ji)停止运(yun)转(zhuan)(zhuan)(zhuan)，其运(yun)行指(zhi)示灯熄(xi)灭。

3、不论采用何种控制方式，当达到(dao)限(xian)水位(wei)时，其超限(xian)水位(wei)信号触点接通，二次控制回路失(shi)电(dian)(dian)，使电(dian)(dian)机停(ting)止运(yun)转，并(bing)发(fa)出声(sheng)光(guang)报苦信号。在电(dian)(dian)机运(yun)行过(guo)程中(zhong)如有(you)事(shi)故出现，事(shi)故指示灯亮，电(dian)(dian)铃自动报苦，这时，按下停(ting)止按钮，迫使电(dian)(dian)机停(ting)止工作。
