760-P5-G5-S5-HI-A20-R-E综合保护继电器
故障识别FA-M3提供了快速识别系统故障的方法，如下图所示。该故障识别系统易于理解，因为它具有层次结构，通过检查每个级别的故障来促进故障分析。指示输出模块的问题严重性和状态FA-M3通过CPU模块上部的LED指示存在或不存在故障，将其分为重大、中度和轻微故障。表A4.1至A4.3总结了每种情况下的故障严重程度和输出模块状态。有关在使用光纤FA总线2型模块的应用中，如果传输线（如光纤电缆）发生故障，FAI信号触点输出和输出模块如何工作的详细信息，请参阅光纤FA母线模块和光纤FA公共汽车2型模块、FA母线2型模块（IM 34M06H45-01E）*1： 可以使用配置的操作控制下的错误时间操作字段设置此错误项的严重性级别。将字段设置为“停止”表示中度故障，而将其设置为“运行”表示轻微故障。默认值为“停止”（中度故障）*2： 可以使用配置的操作控制下的错误时间操作字段设置此错误项的严重性级别。将字段设置为“停止”表示中度故障，而将其设置为“运行”表示轻微故障。默认值为“Run”（小故障）*3： 使用F3SP21、F3SP25或F3SP35 CPU模块Rev.8或更高版本或F3FP36.*4时：高级模块的输出继电器（Yxxxxx）*5： 当检测到电源电压异常时，输出模块根据选择的是标准模式还是立即检测模式而表现不同。每种模式下瞬时电源故障期间的行为如下
故障排除程序
如果出现错误情况，请注意当前情况和症状，然后根据图A4.5所示的流程图排除故障，同时考虑到与其他设备的关系和错误情况的再现性。如果要在主序列或中等序列CPU模块发生故障时重置输出模块的触点，请执行以下操作：使用32点或更少的输出模块，并将配置的“输入/输出设置”下的“停止时输出”字段设置为“重置”。（对于F3SP22/28/38/53/58/59/66/67/71/76模块，也可以使用F3YD64-1F、F3YD 64-1P、F3Y D64-1R、F3WD64 xF和F3WD64-xP模块。）-如果您想在主要或中等顺序CPU模块故障的情况下保持输出模块的触点，请将配置的“输入/输出设置”下的“停止时输出”字段设置为“保持”。行为与CPU模块或输出模块的类型无关*1： 可以使用配置的操作控制下的错误时间操作字段设置此错误项的严重性级别。将字段设置为“停止”表示中度故障，而将其设置为“运行”表示轻微故障。默认值为“停止”（中度故障）*2： 可以使用配置的操作控制下的错误时间操作字段设置此错误项的严重性级别。将字段设置为“停止”表示中度故障，而将其设置为“运行”表示轻微故障。默认值为“Run”（小故障）*3： 高级模块的输出继电器（Yxxxxx）。
Fault Identification
The FA-M3 provides means to quickly identify system faults as illustrated in the following figure. This fault identification system is easy to understand because it is hierarchically structured to facilitate fault analysis by checking for faults at each level.Indicating Problem Severity and Status of Output Module The FA-M3 indicates the presence or absence of failures by the LEDs in the upper section of the CPU module, classifying them into major, moderate and minor failures. Tables A4.1 to A4.3 summarize the failure severity levels and the status of the output module in each case. See the Fiber-optic FA-bus Module and Fiber-optic FA-bus Type 2 Module, FA-bus Type 2 Module (IM 34M06H45-01E) for details on how the FAIL-signal contact output and output module work if a failure arises in a transmission line, such as a fiber-optic cable, in an application where a fiber-optic FA-bus type 2 module is in use.*1: The severity level of this error item can be set using the Error-time Action field under Operation Control of the Configuration. Setting the field to "Stop" indicates a moderate failure whilst setting it to "Run" indicates a minor failure. The default value is "Stop" (moderate failure). *2: The severity level of this error item can be set using the Error-time Action field under Operation Control of the Configuration. Setting the field to "Stop" indicates a moderate failure whilst setting it to "Run" indicates a minor failure. The default value is "Run" (minor failure). *3: When using F3SP21, F3SP25 or F3SP35 CPU modules Rev. 8 or later or F3FP36. *4: Output relays (Yxxxxx) of the advanced modules. *5: When supply voltage abnormality is detected, output modules behave differently depending on whether the standard mode or immediate detection mode is selected. Behaviors during momentary power failure in each mode are as follows
Troubleshooting Procedure
If an error condition occurs, take note of the current situation and symptom, then troubleshoot the problem according to the flowchart shown in Figure A4.5 considering the relationship with the other devices and the reproducibility of the error condition. If you want to reset the contacts of an output module in the event of a major or moderate sequence CPU module failure, do the following: Use an output module with 32 or less points and set the Output When Stopped field under "Input/Output Setup" of the Configuration to "RESET". (For F3SP22/28/38/53/58/59/66/67/71/76 modules, F3YD64-1F, F3YD64-1P, F3YD64-1R, F3WD64-xF and F3WD64-xP modules can also be used.) - If you want to hold the contacts of an output module in the case of a major or moderate sequence CPU module failure, set the Output When Stopped field under "Input/Output Setup" of the Configuration to "HOLD". The behavior is independent of the type of CPU module or output module.*1: The severity level of this error item can be set using the Error-time Action field under Operation Control of the Configuration. Setting the field to "Stop" indicates a moderate failure whilst setting it to "Run" indicates a minor failure. The default value is "Stop" (moderate failure). *2: The severity level of this error item can be set using the Error-time Action field under Operation Control of the Configuration. Setting the field to "Stop" indicates a moderate failure whilst setting it to "Run" indicates a minor failure. The default value is "Run" (minor failure). *3: Output relays (Yxxxxx) of the advanced modules.
