义乌电动卷拉门维修安装定做
故障壹
現象；；；微機操作；。。。。；；就地操作電動門均不動作；；；電動門也沒失電；
檢查步驟；；；檢查電動門機械是否沈；；；行程開關是否正常；；；遠程；。。。。；；就地開關是否通斷良好；；；門頭內斷項保護開關是否正常；
故障原因分析；；；亮綠燈屬正常；；；紅燈為缺項；；；如果紅；。。。。；；綠燈均亮；；；屬斷項保護器故障。紅燈亮；。。。。；；三項電不缺項；；；屬斷項保護器質量問題；
處理方法；；；將斷項保護器的常閉接點短接；；；恢復正常操作。
故障二
現象；；；運行值班員聯系開關能操作；；；門的開關方向不對；；；去就地操作觀察；；；發現門的方向有時對；；；有時不對；；；誤認為電機相序有問題；；；至新換相序後；；；故障仍沒排出；
檢查步驟；；；檢查電動門電機三項直阻是否平衡；；；開；。。。。；；關行程是否正確；；；電動門機械是否沈；
檢查結果；；；電動門電機直阻少壹項；；；行程正常；；；電動門機械不沈；
故障原因分析；；；因電動門機械較輕；；；電機少壹項；；；電機轉動屬自由狀態；；；哪個方向較輕就朝哪個方向轉動；；；所以；；；電動門開關方向無法固定；；；此故障屬缺項所至；；；將電機缺項恢復正常；；；故障消除。Fault one
Phenomenon; microcomputer operation;.... The electric door is not operated on the spot; the electric door is not lost;
Check the steps;; check whether the electric door machine Shen;; stroke switch is normal;; remote;.... Whether on-off switches;; good;; fault protection; door switch is normal;
Analysis of the cause of the fault;; bright green light is normal;; red light is missing;; if red;.... ; green light is bright;; fault protection device. Red light;.... ; three items of electricity are not missing;; the quality of the fault protection device;
The normally closed contact of the fault protector is shorted; and the normal operation is resumed.
Two fault
Phenomenon;; operation; attendant contact switch can switch the wrong direction; operation;; door;;; to observe the operation on the spot;;; find the direction of the door sometimes;;; sometimes not;;; mistaken motor phase problem;;; to the new phase;; fault; still did not discharge;
Check the steps;; check the electric door motor three straight resistance balance;;.... ; whether the closing stroke is correct; whether the electric door machine is shen;
Inspection results;; electric door motor direct resistance of less than one;; normal stroke;; electric door mechanical;
Failure analysis;;; the electric door mechanical lighter;; motor; a little;;; the rotation of the motor is a free state;;; the direction in which light is direction of rotation;;;;; so; the electric door switch direction can not be fixed;;; the fault is short of study;; the lack of normal motor;;;; fault elimination.
