1. Introducció
The TOMZN TOVPD3-63VAYA is an intelligent changeover switch designed to protect electrical circuits from over-voltage, baix voltage, and over-current conditions in a 3-phase system. It automatically cuts off the circuit when voltage or current deviates from set parameters and can automatically reset. This device also functions as an auto phase selector, ensuring continuous power supply by switching to an available phase if one fails.

7. Instruccions de funcionament
7.1. S'ha acabat la funcióview
The device automatically cuts off the circuit when the voltage in any phase is too high or too low, or when the current exceeds the set limit. It also features an auto phase selector to maintain power supply.
7.2. Monitorització en temps real
The digital displays on the front panel provide real-time readings of voltage for each phase (L1, L2, L3) and the total current (A). You can manually calibrate voltage and current if they are not correct using the adjustment keys.
7.3. Configuració dels paràmetres
Utilitza el (SET) button to enter the settings menu and the (Amunt) i (Down) buttons to adjust values. Refer to the table below for detailed parameter descriptions and setting ranges.
Key Settings Explained:
- Power-on delay time: Time needed for power-on after external power cut or recovery. (Setting range: 1s-500s, Factory setting: 10s, Step: 1s)
- Sobrevoltage valor de protecció: Quan voltage of one phase exceeds this value, the protector cuts off the line and switches to the next phase. If all three phases exceed, it cuts off all lines. (Setting range: 230V-300V, Factory setting: 270V, Step: 1V)
- Sobrevoltage recovery value: Quan voltage is 5V or more than 5V lower than the over-voltage protection value, the protector automatically resets. This parameter changes with the over-voltage protection value and does not need to be set independently. (Setting range: 225V-295V, Factory setting: 265V)
- Baix voltage valor de protecció: Quan voltage of one phase drops below this value, the protector cuts off the line and switches to the next phase. If all three phases are under, it cuts off all lines. (Setting range: 140V-210V, Factory setting: 170V, Step: 1V)
- Baix voltage recovery value: Quan voltage is 5V or more than 5V higher than the under-voltage protection value, the protector automatically resets. This parameter changes with the under-voltage protection value and does not need to be set independently. (Setting range: 145V-215V, Factory setting: 175V)
- Over-current protection value: When current exceeds this value, the protector cuts off the line. Setting to OFF disables this function. (Setting range: 3A-63A-OFF, 3A-100A-OFF; Factory setting: 40A/60A, Step: 1A)
- Times of continuous over current protection: If continuous over-current protection exceeds the set value, the protector disconnects the line, requiring manual reset. (Setting range: OFF-1-20, Factory setting: OFF, Step: 1)
- Phase sequence switching detection time: Time to detect if the voltage of the priority phase is stable before switching. OFF means no wait. (Setting range: OFF-1S-500S, Factory setting: 10S, Step: 1S)
- Phase sequence recovery switching settings: ON means when the priority phase returns to normal, it will switch to the priority phase. OFF means it will not switch back. (Setting range: ON/ON-OFF, Factory setting: ON)
- Phase sequence recovery time: Time required to switch to priority phase. (Setting range: OFF-1S-500S, Factory setting: 1S, Step: 1s)
- Over-current protection action time: Time needed for protection action when over current occurs. (Setting range: 0.1s-30s, Factory setting: 1.0s, Step: 0.1s)
- Voltage calibratge: Corrects voltage error. (Setting range: -9.5%-9.5%, Factory setting: 0, Step: 0.5)
- Calibració actual: Corrects current error. (Setting range: -9.5%-9.5%, Factory setting: 0, Step: 0.5)
- Input phase priority selection: Sets the input priority for each phase (e.g., A:L1, B:L2, C:L3). Options include ABC, ACB, BAC, BCA, CAB, CBA. (Factory setting: ABC)

9. Solució De Problemes
| Problema | Causa possible | Solució |
|---|---|---|
| El dispositiu no s'encén | No hi ha alimentació d'entrada; cablejat incorrecte; error intern. | Check power supply. Verify wiring against diagram. If problem persists, contact support. |
| "Fault" indicator is lit | Sobrevoltage, baix voltage, or over-current detected. | Comproveu el volum d'entradatage and current. Device should automatically switch phases or cut off. If manual reset is needed for continuous over-current, press the power button. |
| Vol incorrectetaglectures de corrent elèctric | Error de calibratge. | Utilitzeu el voltage/current calibration setting to adjust readings. |
| Device does not switch phases | Phase sequence switching detection time too long; phase sequence recovery settings are OFF. | Adjust "Phase sequence switching detection time" to a shorter duration or OFF. Ensure "Phase sequence recovery switching settings" is ON if automatic recovery is desired. |
10. Consells d'usuari
- Single-Phase Operation: While designed for 3-phase, some users inquire about single-phase use. The device is primarily for 3-phase systems (e.g., L1 at 127 VAC in a 3-phase context). For dedicated single-phase protection, a different model might be more suitable. Consult an electrician for specific application requirements.
- Calibració: If you notice discrepancies in voltage or current readings, utilize the calibration feature in the settings menu for accurate monitoring.
- Priority Phase: Carefully consider and set your input phase priority selection (ABC, ACB, etc.) based on your specific electrical setup to ensure optimal power continuity.
