When we use electric actuators, a variety of faults often occur, such as the failure of the black screen on power-up, so today I will explain in detail how to deal with this fault.
Before explaining the solution of the black screen, we must first analyze the reasons for this failure, so that everyone can understand the purpose of the measures to solve the black screen of the electric actuator.
Then the main reasons for the black screen of the electric actuator, through daily detection of the cause of the black screen of the electric actuator, comprehensive consideration of brush selection, mainly include the following:
1. A black screen appears on the electric actuator, either the voltage is incorrect, or the power supply is out of phase.
2. There is an error in the wiring of the electric actuator. One of the power wires of the electric actuator is connected to the ground terminal.
3. Poor contact inside the electric actuator.
4. The fuse of the electric actuator is burnt out.
5. The display of the electric actuator is abnormal.
Then the following explains the solutions to these reasons for electric actuators.
1. First, we use a multimeter to detect the voltage on the terminals. If the voltage is found to be too low, we will take corresponding boosting measures. If the voltage is normal, check the inside of the electric actuator.
2. Check whether any power cord is connected to the wire terminal. If it is found to be wrong, reconnect it.
3. Check whether the plug inside the electric actuator is detached. If it is detached, reinsert it.
4. Also use a multimeter to measure whether the internal fuse is damaged. If it is burnt out, replace the fuse of the same type.
5. If the display screen is found to be defective, the operation display screen can be replaced.
