ABB DPT-CB010系列双电源自动转换开关；DPT63-CB010 C50 3P
遇到开关不能正常工作情况时，请首先按复位按钮看可否排除故障，然后检查主备开关的进线、二次采样线是否正常，接插件是否有松动、虚接情况。下面供常见故障排除时参考。
When the switch can not work normally, please first press the reset button to see if the fault can be eliminated. Then check the incoming line of the main switch, whether the two sampling line is normal, whether the connector has loose or virtual connection. The following is for reference when troubleshooting.
一、接入电源自动转换开关不动作，控制器灯不亮
First, the automatic switch of the access power doesn't act. The controller doesn't light.
可能出现部位：
Possible location:
1.安装接线是否接正确及接实
1. installation connection is correct and true
2.熔断器熔芯是否熔断
2. fuse core melting or not
解决方法：
Resolvent：
1.检查断路器进线端有无脱落和接虚，如有脱落重新接好
1. check whether the circuit breaker has any drop and connection, and if there is any shedding, it will be reconnected.
2.对于3极ATS中性线应接入中性端子上
2. for the 3 pole ATS neutral line should be connected to the neutral terminal
3.更换熔断器
3. replacement fuse
二、接入电源自动转换开关不工作，控制器灯亮
Two, the automatic switch of the access power does not work, and the controller lights up.
可能出现部位：
Possible location:
1.自动转换开关未置自动位置
1. non automatic position of automatic switch switch
2.自动转换开关延时调整过长
2. time delay adjustment of automatic conversion switch
解决方法：
Resolvent：
1.自动转换开关自动/手动切换开关处在手动位置，同时B型控制器自动切换灯不在自动位置
1. automatic transfer switch automatic / manual switch is in manual position. Meanwhile, B controller automatically switches the lamp off.
2.自动转换开关置在自投不自复或互为备用状态下。不能备用回路转为主用回路，如需改为自投自复状态时重新调整拨码开关及控制器设置
2., the automatic transfer switch is placed in the state of automatic switching or standby. It is not possible to turn the standby loop into the main circuit, if necessary, adjust the dial switch and the controller settings when changing to the self return state.
3.自动转换电器切换延时被调整，重新调整延时拨码开关及控制器的设置
3., automatic switching device switching delay is adjusted, re adjust the time delay dial switch and controller settings.
三、控制器电源灯闪烁
Three, the power lamp flicker of the controller
可能出现部位：
Possible location:
1.进线电源故障 a.电源超压b.电源线路接触不良c.控制器故障
1., incoming line power failure, A. power overvoltage, B. power supply line bad contact, C. controller failure.
2.电源灯闪烁，蜂鸣器报警
2. power lights flicker, buzzer alarm
解决方法：
Resolvent：
1.重新调整进线电源电压
1. readjust the line power supply voltage
2.检查进线电源是否有断相，或虚接现象，如存在接实，其中包括自动转换电器的采样线。
2., check whether the incoming line power has phase interruption or virtual connection phenomenon, such as the existence of connection, including automatic conversion of electrical sampling line.
3.控制器插件重新接插或更换控制器。
The 3. controller plug-in reconnects or changes the controller.
4.进线电源端中性线与相线接反，重新更正接好。
4., the neutral line of the incoming power supply is connected with the phase line, and it is re corrected.
四、自动转换开关脱扣灯亮
Four, automatic switch off switch off light
可能出现部位：
Possible location:
1.运输原因造成自动转换电器断路器 脱扣
1. cause of automatic switching of electric circuit breaker.
2.使用中造成自动转换电器的断路器脱扣
2., circuit breaker tripping caused by automatic conversion of electrical appliances.
