Automatic Voltage Protector Troubleshooting, Repairs and Help

Reasons why the automatic voltage protector does not light up

[1] Power failure:

If the power line is short-circuited or open-circuited, or the power plug has poor contact, the automatic voltage protector will not light up. At this time, you need to check whether the power line is in good contact and whether there is a power supply.

[2] Switch damage:

Damage to the switch inside the automatic voltage protector will also cause it to not light up. If this happens, you need to check and replace the switch.

[3] Internal instrument failure:

Failure or aging of small switches, bulbs, and other components inside the automatic voltage protector will also cause it to not light up. At this time, you need to check and replace the instrument.

The solution to the automatic voltage protector not lighting up

[1] Check the power line:

First, check whether the power line is short-circuited or open-circuited and whether the power plug has good contact. If a problem is found, you need to reconnect it to ensure a normal power supply.

[2] Replace the switch:

If the switch is damaged and causes it to not light up, you need to replace the damaged switch. During the replacement process, you need to pay attention to the specifications and models of the switch, as well as the wiring method of the connection line.

[3] Replace parts:

If the parts inside the instrument are faulty or aging, you need to replace the faulty parts. During the replacement process, you need to pay attention to the specifications and models of the parts, as well as the wiring method of the connection line.

Automatic voltage protector maintenance guide

[1] Check the device status

Before repairing, you need to check the overall status of the device. Observe whether the appearance of the protector is damaged, deformed, or burnt, and check whether the indicator light is displayed normally. At the same time, you also need to check whether the wiring of the protector is firm, loose, or short-circuited. If the device is found to be obviously damaged or abnormal, it is recommended to stop using it immediately and contact a professional electrician or relevant technician for processing.

[2] Diagnose the cause of the fault

If the device looks normal but cannot work properly, then you need to diagnose the cause of the fault. First, you can check whether the internal circuit of the protector is short-circuited, open-circuited, or damaged. You can use tools such as a multimeter to detect and check whether each part is faulty. In addition, you can also check whether the action parameter settings of the protector are correct and whether the device cannot work properly due to misoperation or improper parameter settings.

[3] Repair measures

After diagnosing the cause of the fault, you can take appropriate repair measures. If the fault is caused by internal circuit damage or component damage, the corresponding circuit components or circuit boards need to be replaced. During the replacement process, it is necessary to select components that match the original equipment and install and connect them correctly according to the equipment manual. If the fault is caused by improper parameter settings, it is necessary to reset the action parameters of the protector to ensure that it can work normally.

Automatic voltage protector AC preventive measures

[1] Select a suitable voltage protector: Select a suitable voltage protector according to the rated voltage and rated current of the electrical equipment to be protected.

[2] Reasonable use of electrical equipment: Avoid long-term overload or short-circuit use to extend the life of electrical equipment.

[3] Regular inspection: Regularly check the working status and connection status of the protector and the electrical equipment to be protected to prevent faults.
