How to judge the operating status of the fan through this indicator light？

之前我们介绍过，EBM新款的EC风机在电机底座上配备了一个状态指示灯，本期我们就来讲解一下如何通过该指示灯判断风机的运行状态。

We have introduced before that EBM's new EC fan is equipped with a status indicator light on the motor base. In this video, we will explain how to judge the operating status of the fan through this indicator light.

在风机上电之后会先进入自检状态，此时指示灯呈绿色并且会闪烁，一般闪烁三次后，如果风机没有任何问题，指示灯将由绿色闪烁变成绿色常亮，此时我们可以正常操控风机。

After the fan is powered on, it will first enter the self-test state. At this time, the indicator light will be green and flash. Generally, after flashing three times, the indicator light will change from green flashing to green and steady on if there is no problem with the fan. At this time, we can control the fan normally.

如果风机检测到异常，则会发出警告，此时指示灯会变成黄色闪烁状态，但风机并不会停机，只是发出警告并激活相应的保护功能。

If the fan detects an abnormality, it will issue a warning. At this time, the indicator light will turn yellow and flash, but the fan will not stop. It will only issue a warning and activate the corresponding protection function.

而当风机检测到严重故障时，指示灯会变成红色闪烁，此时风机将停止运行。

When the fan detects a serious fault, the indicator light will turn red and flash, and the fan will stop running.

当风机出现警告时，虽然风机不会停机，但依然需要操作人员及时排查问题，避免风机由异常转为故障，影响现场的生产和使用。

When a fan warning occurs, although the fan will not stop, the operator still needs to troubleshoot the problem in time to prevent the fan from turning abnormal into a failure, which will affect on-site production and use.

当风机处于不同的警告或故障状态时，指示灯闪烁的次数也不同，我们可以通过数出一个周期内指示灯闪烁的次数来判断当前的警告和故障信息，对应关系如下

When the fan is in different warning or fault states, the number of times the indicator light flashes is also different. We can determine the current warning and fault information by counting the number of times the indicator light flashes in a cycle. The corresponding relationship is as follows
