When the voltage is too high or too low, the protector will automatically protect and flash continuously. At this time, it is necessary to troubleshoot the voltage fluctuation protector.
(1)Check the power supply voltage.
First, you must check whether the power supply voltage meets the rated voltage range of the voltage fluctuation protector. If the voltage is too high or too low, the protector will trigger the protection. If the voltage meets the standard, first check whether the power cable of the protector is damaged or has poor contact.
(2)Check the protector settings.
The protector has multiple protection modes. If the settings are improper, the protector will also have a continuous flashing fault. Therefore, it is necessary to check whether the settings are correct.
(3)Check the load resistance.
If the voltage fluctuation protector detects that the load resistance of the circuit is abnormal, it will automatically trigger the protection. Therefore, it is necessary to check whether the load resistance of the circuit is normal.
Voltage fluctuation protector maintenance method
(1)Replace the voltage fluctuation protector.
If the above troubleshooting does not find the problem, you need to replace the protector.
(2)Repair the circuit
If you can’t find the specific problem, you can consider repairing the circuit. It may be caused by aging of the line, poor contact, or damage to the circuit components. Professionals are required for repair.
In short, the voltage fluctuation protector is too high or too low and keeps flashing. This is a common fault that requires timely troubleshooting and repair to ensure the circuit’s normal operation. Before troubleshooting, it is necessary to check the power supply voltage, protector settings, and load resistance and replace the protector or repair the circuit in time.
