電動(dong)門(men)由于結構復雜所(suo)以出故障的幾率比較(jiao)大。很多(duo)時(shi)(shi)候電動(dong)門(men)會出現幾個小問題，這里只要給大家講兩(liang)個現象分析(xi)和處理(li)方法。電動(dong)門(men)有(you)時(shi)(shi)會出現不管是微機(ji)操作還是就地操作都沒(mei)反應的現象，檢查電源發現也不是電動(dong)門(men)沒(mei)有(you)電，那到底是什么原因呢？

你(ni)可以(yi)先檢查電動門(men)機械(xie)是(shi)(shi)否沉，行程開(kai)(kai)關是(shi)(shi)否正常，遠程、就地開(kai)(kai)關通(tong)電是(shi)(shi)否良好，門(men)頭內的保(bao)護開(kai)(kai)關是(shi)(shi)否正

常等等，如(ru)(ru)果(guo)是(shi)綠(lv)燈(deng)亮的話就是(shi)正(zheng)常的，如(ru)(ru)果(guo)是(shi)紅(hong)燈(deng)就會(hui)缺項(xiang)(xiang)，如(ru)(ru)果(guo)紅(hong)綠(lv)燈(deng)都亮了就是(shi)斷(duan)項(xiang)(xiang)保護(hu)器出故障(zhang)了，如(ru)(ru)果(guo)紅(hong)綠(lv)燈(deng)都不亮就是(shi)屬(shu)斷(duan)項(xiang)(xiang)保護(hu)器質量的問題。

若(ruo)要(yao)電動(dong)門恢(hui)復正(zheng)常則可以將斷項保護器(qi)的(de)常閉(bi)接點短(duan)接，然后電動(dong)門就能恢(hui)復正(zheng)常操作(zuo)了。

還有一種現(xian)象(xiang)就是(shi)(shi)(shi)電(dian)動(dong)(dong)(dong)門(men)(men)(men)的(de)開關方(fang)向不(bu)對，這(zhe)不(bu)是(shi)(shi)(shi)電(dian)機(ji)相(xiang)序的(de)問題(ti)，而是(shi)(shi)(shi)要(yao)檢查電(dian)動(dong)(dong)(dong)門(men)(men)(men)電(dian)機(ji)三項直阻是(shi)(shi)(shi)否(fou)平衡(heng)，開光形行程(cheng)是(shi)(shi)(shi)否(fou)正(zheng)確，電(dian)動(dong)(dong)(dong)門(men)(men)(men)的(de)機(ji)械是(shi)(shi)(shi)否(fou)沉(chen)。如果電(dian)機(ji)少一項電(dian)動(dong)(dong)(dong)門(men)(men)(men)電(dian)機(ji)的(de)轉動(dong)(dong)(dong)就屬于(yu)自由狀態，哪個方(fang)向輕就往哪個方(fang)向轉，所以電(dian)動(dong)(dong)(dong)門(men)(men)(men)的(de)開關方(fang)向才有問題(ti)，所以要(yao)解決的(de)就是(shi)(shi)(shi)電(dian)動(dong)(dong)(dong)門(men)(men)(men)電(dian)機(ji)缺項的(de)問題(ti)了。
