K2A20L模块常见故障处理

故障名称：模块显示屏问题

Fault name: Module displaying screen fault

故障现象：模块不显示或黑屏

Fault phenomenon: The module does not display or the black screen

原因分析：监控器未检测到数据或没工作

Reason analysis: The monitor has not inspected the data or has not worked

处理方法：检查模块与托架接触是否良好，模块内部所有接口有无松动,如松动需重新插上,如接触良好需与厂家联系

Processing method: Inspect whether the module contact with the bracket well, the module interior all interfaces whether is reliable, if become less crowded must insert again, if contact well must relate with the factory

故障名称：模块保护故障

Fault name: Module protection fault

故障现象：报过温保护、过压保护

Fault phenomenon: The monitor sends out the over-warm protection, the over-voltage protection

原因分析：模块监控未检测到数据

Reason analysis: The module monitor has not inspected the data

处理方法：检查模块内部连接到显示板的接口有无松动。如松动需重新插上，模块工作正常；如重新插上后，仍不能排除保护故障，则需与厂家联系

Processing method: Inspect the module interior interface what connect to the displaying panel whether become less crowded. If become less crowded must insert again, the module works normally; if after insert, still could not eliminate the protection fault must relate with the factory

故障名称：模块电流偏差

Fault name: Module current deviation

故障现象：模块电流有显示，但比实际输出大

Fault phenomenon: There is the module current displaying, but is bigger than the actual output

原因分析：电流采集异常

Reason analysis: The current collection is unusual

处理方法：在模块显示器上校准电流，检查模块内部所有接口有无松动,如松动需重新插上,如接触良好需与厂家联系

Processing method: Calibrate current on the module monitor, inspect the module interior all interfaces whether become less crowded, if become less crowded must insert again, if contact well must relate with the factory

故障名称：模块欠压

Fault name: The module under-voltage

故障现象：模块报欠压报警,输出电压低于180V（220V系统）或90V（110V系统）

Fault phenomenon: The module sends out the under-voltage alarm, the output voltage is lower than 180V (the 220V system) or 90V (the 110V system)

原因分析：模块输出保险损坏或模块处于限流状态

Reason analysis: The module output insurance has been damaged or the module is at the limited current condition

处理方法(Processing method)：

1.      查看系统是否处于限流均充状态，如是，则属正常；

Inspect the system whether is at the limited current equalize condition, if is, then is normally;

2.      检查模块输出保险有无损坏，如保险正常，则需与厂家联系。

Inspect the module output insurance whether has been damaged, if insurance normal, then must relate with the factory.

故障名称：模块通讯问题

Fault name: Module communication fault

故障现象：主监控间隔循环报模块通讯故障

Fault phenomenon: The host monitor sends out the module communication fault discontinuously and circularly

原因分析：一台模块干扰其他模块通讯故障

Reason analysis: A module disturbs other module communication fault

处理方法：单个模块与主监控进行通讯，查出具体的模块需与厂家联系

Processing method: The single module communicates with the host monitor, find out the concrete fault module to relate with the factory
