1. Failure of electric actuator: 
After energizing the electric actuator, it is found that the power indicator light is not on, the server board has no feedback, and the signal does not act. 
Fault diagnosis and repair process: 
Because the power indicator light is not on, first check whether the safety tube is open, check that the safety tube is intact, synthesize the fault phenomenon, we can infer that the fault may occur in the power supply part of the service board, and then check the power indicator light.Use multimeter detection to find that the indicator light is open, replace the indicator light troubleshooting. 
Conclusion: the open circuit of the power indicator will cause the whole server board not to work. 
2. Fault phenomenon: (found in debugging). 
After the actuator of the electric actuator is powered on, the signal can be turned on and off without action. 
Fault diagnosis and repair process: 
First carefully check the feedback line, confirm that the feedback signal is fault-free, turn on the indicator light when the signal is turned on, indicating that the on is normal, the indicator light is not on when the signal is turned off, indicating that there is a problem with the thyristor part, first check the turn-off indicator.Using multimeter to detect and discover customs indication. 
Open the lamp and troubleshoot it after replacement. 
Conclusion: the thyristor does not act when the indicator light is not on (open circuit).
