4. Arahan Operasi
The SVP719 features three LED displays and four control buttons for monitoring and configuration.
4.1 Paparan LED
- Voltage Display (V): Menunjukkan vol masa nyatatage litar.
- Current Display (A): Shows the real-time current flowing through the circuit.
- Kilowatt-hour Display (kWh): Shows the accumulated energy consumption.
4.2 Butang Kawalan
- Butang SET: Used to enter the parameter setting mode and cycle through different adjustable parameters.
- Butang Anak Panah Atas: Used to increase the value of a selected parameter.
- Butang Anak Panah Bawah: Used to decrease the value of a selected parameter.
- Butang HIDUP/MATI: Used to manually turn the power supply to the load ON or OFF.
4.3 Manual ON/OFF Operation
Tekan ke HIDUP/MATI button to manually switch the power to the connected load. The display will show 'OFF' when power is disconnected and 'ON' when connected.
4.4 Kilowatt-hour (kWh) Reset
To reset the accumulated Kilowatt-hour (kWh) reading, press the Anak panah ke bawah dan SET buttons simultaneously. The kWh display will reset to 000.0.

5. Tetapan Parameter
The SVP719 allows for adjustment of various protection parameters. All parameters are adjustable within specified ranges.
5.1 Entering Setting Mode
Tekan dan tahan butang SET button for approximately 3 seconds to enter the parameter setting mode. The first adjustable parameter will appear on the display.
5.2 Cycling Through Parameters
Once in setting mode, short press the SET button to cycle through the parameters sequentially. Each press will display the next parameter.
5.3 Adjusting Parameter Values
When a desired parameter is displayed, use the Anak panah atas dan Anak panah ke bawah buttons to adjust its value. The display will flash while adjusting.
5.4 Saving Settings and Exiting
After adjusting a parameter, wait for approximately 5 seconds without pressing any button. The device will automatically save the new setting and exit the setting mode, returning to normal operation.
5.5 Parameter Boleh Laras
- U> (Over-voltage Protection Value): Menetapkan volum atastage limit. If the voltage exceeds this value, the protector will trip.
- U< (Under-voltage Protection Value): Menetapkan volum yang lebih rendahtage limit. If the voltage drops below this value, the protector will trip.
- I> (Over-current Protection Value): Sets the maximum current limit. If the current exceeds this value, the protector will trip.
- t-on (Fault Recovery Delay Time): Sets the delay before the device automatically reconnects after a fault (over/under voltage, over-current) has cleared.
- t-off (Reset/Start Delay): Sets the delay for initial power-on or manual reset.
- CAL-A (Current Calibration): Allows for fine-tuning of the current measurement.
- CAL-V (Voltage Calibration): Allows for fine-tuning of the voltage pengukuran.
- CLP (Clear kWh): Resets the energy consumption counter.
6. Ciri-ciri Perlindungan
The SVP719 provides robust protection for your electrical equipment.
6.1 Lebih-Jilidtage Perlindungan
When the circuit voltage melebihi vol lebih yang ditetapkantage protection value (U>), the protector will instantaneously cut off the power supply to prevent damage to connected devices. The display will indicate an over-voltage syarat.
6.2 Bawah-Voltage Perlindungan
If the circuit voltage drops below the set under-voltage protection value (U<), the protector will immediately disconnect the power. The display will indicate an under-voltage syarat.
6.3 Perlindungan Lebihan Semasa
Should the current drawn by the load exceed the set over-current protection value (I>), the device will trip and cut off power to protect the circuit and load.
6.4 Automatic Recovery
After a fault condition (over-voltage, bawah-voltage, or over-current) has been detected and the power supply is cut off, the SVP719 will continuously monitor the circuit. Once the voltage and current return to normal operating ranges for the duration of the set recovery delay time (t-on), the protector will automatically restore power to the load.
7. Penyelenggaraan
To ensure optimal performance and longevity of your SVP719, follow these simple maintenance guidelines:
- Regularly inspect the device for any signs of physical damage or loose connections.
- Keep the device clean and free from dust and debris. Use a dry, soft cloth for cleaning.
- Jangan gunakan pembersih atau pelarut yang melelas.
- Pastikan pengudaraan yang mencukupi di sekitar peranti untuk mengelakkan terlalu panas.
8. Penyelesaian masalah
If you encounter issues with your SVP719, refer to the following common problems and solutions:
| Masalah | Kemungkinan Punca | Penyelesaian |
|---|---|---|
| Peranti tidak dihidupkan | No input power; incorrect wiring | Check main power supply; verify wiring connections as per diagram. |
| Power cuts off frequently | Voltage/current outside set limits; sensitive settings | Check actual voltage/current; adjust protection parameters (U>, U<, I>) to appropriate levels for your load. |
| Peranti tidak pulih secara automatik | Fault condition still present; recovery delay too long | Pastikan voltage/current has returned to normal; check and adjust 't-on' recovery delay setting. |
| kWh reading is inaccurate | Penentukuran diperlukan | Perform current and voltage calibration (CAL-A, CAL-V) if you have a reference meter. |
