4. **Appliance Connection**: Plug the electrical appliance you wish to protect into the socket of the EAMPS-1-VA.
5. **Initial Power-On**: The device will power on and display the current voltage and current readings.

Operating Instructions

The EAMPS-1-VA allows you to adjust various protection parameters. Use the 'SET' button to enter setting mode and the Up/Down arrows to adjust values.

1. **Enter Setting Mode**: Press and hold the 'SET' button for 5 seconds. The display will show the current parameter (e.g., P1).
2. **Navigate Parameters**: Press 'SET' briefly to cycle through parameters P1 to P10.
3. **Adjust Values**: When a parameter is displayed, use the Up (▲) and Down (▼) arrow buttons to adjust its value.
   • **P1: Over-Voltage Protection Value (V)**: Range 240-300V, Default: 270V.
   • **P2: Over-Voltage Recovery Value (V)**: Range 235-295V, Default: 265V.
   • **P3: Under-Voltage Protection Value (V)**: Range 140-200V, Default: 170V.
   • **P4: Under-Voltage Recovery Value (V)**: Range 145-205V, Default: 175V.
   • **P5: Over-Current Protection Value (A)**: Range 1-16A, Default: 16A.
   • **P6: Power-on Delay Time (S)**: Range 1-300 seconds, Default: 5 seconds.
   • **P7: Voltage Protection Recovery Delay Time (S)**: Range 5-300 seconds, Default: 30 seconds.
   • **P8: Current Protection Recovery Delay Time (S)**: Range 30-300 seconds, Default: 30 seconds.
   • **P9: Voltage Regulation**: Range -9.5% to +9.5%, Default: 0. (For fine-tuning voltage display accuracy)
   • **P10: Current Regulation**: Range -9.5% to +9.5%, Default: 0. (For fine-tuning current display accuracy)
4. **Exit Setting Mode**: After adjusting all desired parameters, continue pressing 'SET' until 'OFF' is displayed, then press 'SET' one more time to return to the main display. The device will save your settings automatically.
5. **Manual Reset to Factory Defaults**: In setting mode, press and hold the Up (▲) and Down (▼) keys simultaneously for 3 seconds to restore the factory default parameters.

Features and Protection Functions

• **Under Voltage Protection (UV)**: Automatically cuts off power if the voltage drops below the set threshold (P3).
• **Over Voltage Protection (OV)**: Automatically cuts off power if the voltage rises above the set threshold (P1).
• **Over Current Protection (OA)**: Automatically cuts off power if the current drawn exceeds the set threshold (P5).
• **Adjustable Recovery Delay**: Configurable delay times (P6, P7, P8) before power is restored after a fault, preventing rapid cycling and protecting sensitive equipment.
• **Automatic Recovery**: The device automatically restores power once voltage and current return to safe levels after the set delay.
• **Real-time Display**: Dual LED displays show current voltage and current readings.
• **Safety Socket Design**: Prevents children from accidentally inserting objects into the socket.
• **Durable Construction**: Made with PC flame-retardant material and high conductivity copper plates for safety and longevity.

Maintenance

• **Cleaning**: Wipe the device with a dry, soft cloth. Do not use abrasive cleaners or liquids.
• **Storage**: Store in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
• **Regular Check**: Periodically check the device and its connections for any signs of wear or damage.

Troubleshooting

• **Device not powering on**:
  • Ensure the wall outlet has power.
  • Check if the device is securely plugged into the wall outlet.
• **Appliance not receiving power**:
  • Check the device's display for any fault indicators (e.g., >V, <V, >A LEDs).
  • Verify that the appliance is correctly plugged into the protector socket.
  • Ensure the appliance itself is functioning correctly.
  • Wait for the set delay time (P6, P7, P8) if a protection event has occurred.
• **Incorrect voltage/current readings**:
  • Use parameters P9 (Voltage Regulation) and P10 (Current Regulation) to calibrate the display if you have a known accurate reference meter.
  • Ensure the device is not overloaded beyond its 16A capacity.
• **Device frequently tripping**:
  • Review your set protection parameters (P1-P5) to ensure they are appropriate for your electrical environment and connected appliances.
  • Consider if the connected appliance is drawing excessive current or if the supply voltage is unstable.

User Tips

• **Optimal Settings**: For most household appliances, using the default settings for voltage and current protection is usually sufficient. However, for sensitive or specific equipment, consult their manuals for recommended operating ranges and adjust P1-P5 accordingly.
• **Delay Times**: The recovery delay times (P6, P7, P8) are crucial. Longer delays can prevent damage from rapid power fluctuations, especially for appliances with motors or compressors (e.g., refrigerators, air conditioners).
• **Monitoring**: Regularly check the LED display to understand your home's voltage and current patterns, which can help identify potential electrical issues before they cause damage.
• **Child Safety**: The built-in safety socket design is a great feature, but always supervise children around electrical outlets.
