5. Enstalasyon ak Enstalasyon
The STVP-932 is designed for DIN rail mounting within an electrical enclosure. Ensure proper ventilation and clearance around the device.
5.1 Montaj
Attach the protector to a standard 35mm DIN rail by snapping the clips on the back of the device onto the rail. Ensure it is securely fastened.
5.2 Dyagram fil elektrik
Follow the wiring diagram carefully to connect the STVP-932 to your three-phase electrical system. The device has 'IN' terminals for incoming power (L1, L2, L3, N) and 'OUT' terminals for protected outgoing power (L1, L2, L3, N).
Etap Koneksyon:
- Connect the incoming three-phase power supply (L1, L2, L3, N) to the 'IN' terminals of the STVP-932.
- Connect the 'OUT' terminals (L1, L2, L3, N) of the STVP-932 to the load or downstream circuit protection devices (e.g., air circuit breaker).
- Asire w tout koneksyon yo byen sere epi byen fiks pou anpeche kontak ki lach epi surchof.
6. Operasyon Enstriksyon
6.1 Digital Display
Ekspozisyon dijital la montre volim an tan reyèltage readings for each phase (A, B, C). In normal operation, it cycles through these readings or displays the current status.
6.2 Anviwònman Paramèt
Use the 'SET' button to enter the parameter setting mode. The 'Up' and 'Down' arrow buttons are used to navigate through parameters and adjust their values. Press 'SET' again to confirm a setting and move to the next parameter, or to exit the setting mode.
Adjustable parameters include:
- Sou-voltage protection value (Uvo)
- Sou-voltage valè rekiperasyon
- Sou-voltagtan aksyon pwoteksyon e
- Anba-voltage protection value (Uve)
- Anba-voltage valè rekiperasyon
- Anba-voltagtan aksyon pwoteksyon e
- Twa-faz voltage unbalance protection value
- Twa-faz voltage unbalance protection action time
- Delay time after power-on
- Fault recovery delay time
6.3 Reset Mode Selection
The device supports different reset modes. Consult the English manual included in the package for detailed instructions on selecting the appropriate reset mode for your application.
6.4 Fault Inquiry and Factory Reset
The device allows for fault inquiry to review past protection events. A factory data reset option is also available to restore all parameters to their default settings.
NAN. Depanaj
This section provides guidance on common issues you might encounter with the STVP-932.
| Pwoblèm | Kòz posib | Solisyon |
|---|---|---|
| Aparèy la deklanche souvan | Voltage fluctuations (over/under voltage), phase unbalance, incorrect settings. | Check power supply stability. Adjust protection thresholds (Uvo, Uve) and action times. Verify load balance across phases. |
| Pa gen ekspozisyon/Pa gen kouran | No input power, incorrect wiring, internal fault. | Ensure main power is on. Check input wiring (L1, L2, L3, N). If wiring is correct and power is present, contact support. |
| Device does not reset | Continuous fault condition, incorrect reset mode setting. | Ensure the fault condition has cleared. Check the configured reset mode and recovery delay time. |
| Incorrect voltage lekti | Loose connections, sensor issue. | Verify all wiring connections are secure. If the issue persists, contact support. |
8. Antretyen
- Regularly inspect the device for any physical damage or signs of overheating.
- Kenbe aparèy la pwòp epi san pousyè ak debri. Sèvi ak yon twal sèk epi mou pou netwaye.
- Periodically check all wiring connections to ensure they remain tight and secure.
- Do not attempt to open or repair the device yourself, as this may void any warranty and pose a safety risk.
9. Konsèy itilizatè yo
Based on common usage and feedback, here are some tips for optimizing your experience with the STVP-932:
- Premye konfigirasyon: When first installing, set the protection values slightly wider than your expected normal operating range to avoid nuisance tripping, then fine-tune as needed.
- Siveyans: Regularly check the digital display to understand the typical voltage behavior of your system, which can help in setting optimal protection parameters.
- Reta Rekiperasyon: Utilize the fault recovery delay time setting to prevent rapid on/off cycling of equipment during intermittent power issues, protecting sensitive loads.
