電動(dong)門由(you)于結構復雜所以出故障的幾率比較大。很多時(shi)候電動(dong)門會出現幾個(ge)小問題，這(zhe)里只要給大家講兩個(ge)現象分析和處理方(fang)法。

電(dian)(dian)動(dong)門有(you)時會出現不(bu)(bu)管是微(wei)機操(cao)作還是就(jiu)地操(cao)作都沒反應的現象，檢查電(dian)(dian)源發(fa)現也不(bu)(bu)是電(dian)(dian)動(dong)門沒有(you)電(dian)(dian)，那到底(di)是什么(me)原因呢？

你可(ke)以(yi)先檢查電動門(men)機械是否(fou)沉，行程開(kai)關(guan)是否(fou)正常，遠程、就地開(kai)關(guan)通電是否(fou)良好，門(men)頭內的保(bao)(bao)護(hu)開(kai)關(guan)是否(fou)正常等(deng)等(deng)，如(ru)果(guo)是綠燈(deng)亮的話就是正常的，如(ru)果(guo)是紅(hong)燈(deng)就會(hui)缺項(xiang)，如(ru)果(guo)紅(hong)綠燈(deng)都亮了(le)(le)就是斷項(xiang)保(bao)(bao)護(hu)器出故障(zhang)了(le)(le)，如(ru)果(guo)紅(hong)綠燈(deng)都不(bu)亮就是屬斷項(xiang)保(bao)(bao)護(hu)器質量的問題。

若要電(dian)動門(men)恢復正常則可以將斷項保護器的常閉(bi)接點短(duan)接，然后(hou)電(dian)動門(men)就能(neng)恢復正常操(cao)作了。

還有一種現象就是電(dian)(dian)(dian)動門(men)的開關(guan)方(fang)(fang)向(xiang)不(bu)對，這不(bu)是電(dian)(dian)(dian)機(ji)(ji)相(xiang)序的問(wen)題(ti)(ti)，而是要(yao)檢查電(dian)(dian)(dian)動門(men)電(dian)(dian)(dian)機(ji)(ji)三項(xiang)直阻(zu)是否(fou)平(ping)衡(heng)，開光形行(xing)程是否(fou)正(zheng)確，電(dian)(dian)(dian)動門(men)的機(ji)(ji)械是否(fou)沉。如果電(dian)(dian)(dian)機(ji)(ji)少一項(xiang)電(dian)(dian)(dian)動門(men)電(dian)(dian)(dian)機(ji)(ji)的轉(zhuan)動就屬于自由狀態，哪個(ge)(ge)方(fang)(fang)向(xiang)輕就往哪個(ge)(ge)方(fang)(fang)向(xiang)轉(zhuan)，所(suo)(suo)以電(dian)(dian)(dian)動門(men)的開關(guan)方(fang)(fang)向(xiang)才有問(wen)題(ti)(ti)，所(suo)(suo)以要(yao)解決的就是電(dian)(dian)(dian)動門(men)電(dian)(dian)(dian)機(ji)(ji)缺(que)項(xiang)的問(wen)題(ti)(ti)了。
