济南卷帘门厂解读卷帘门无动作响应
2015-6-25 16:39:09

故障现象一:卷帘门不动作(现场按键操作毫无反应)

Fault phenomenon: rolling door does not act (the site key operation is no response)
排查分析:
Investigation and analysis:
1、确认控制箱内是否送上主电
1, to confirm whether the control box is sent to the main power
2、控制面板是否有问题(可以在卷帘门控制箱内的端子排上直接短接下降端子触点和COM端触点,看卷帘门是否动作,如果卷帘动作,证明控制面板损坏)
2, the control panel is a problem (which can be in rolling shutter door control box terminal row short direct connection drop terminal contacts and com terminal contacts, rolling shutter door to see whether or not the action, if rolling action. The experiment shows that the control panel damage)
3、假设上述两项都没问题后,检查卷帘门上下限位开关,是否上下限位开关都没有复位弹出(正常卷帘门上到顶的状态下,上限位开关是被转子卡轮压下去的,下限位开关是弹出的状态)
3, assume that the two are no problem, check the shutter door upper and lower limit switches, whether on the lower limit switch are not reset pop-up (normal rolling shutter door to reach the summit of the state, the limit switch is by rotor card wheel presses down, the lower limit switch is pop)
4、如果控制箱内供三相电机的线用的是接触器的控制主板,那么可以在接触器上直接用螺丝刀之类的工具压下去 使接触器处于吸合状态 观察电机是否动作(以排除电机烧坏的可能)
4, if control box for three-phase motor line contactor control board, then it can be in contact directly with a screwdriver like tool is pressed down the contacts in attracting state observation whether the motor action (to exclude the possibility of a burned out motor)
注:判断电机是否烧毁,可以用兆欧表(也就是俗称的摇表测对地绝缘程度)若阻值偏向零刻度 则证明 线圈已烧坏
Note: to determine whether the motor burned, can use megohm table (is commonly known as the shake table test of insulation level) if the resistance bias zero scale proof coil has burnt out
