7. Cara ngungkulan
This section provides guidance on common issues you might encounter with the STVP-932.
| Masalah | Mungkin Cukang lantaranana | Solusi |
|---|---|---|
| Device trips frequently | 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. |
| Teu aya tampilan/Teu aya daya | 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. |
| salah voltage bacaan | Loose connections, sensor issue. | Verify all wiring connections are secure. If the issue persists, contact support. |
