7. Баррасии мушкилот
| Мушкилот | Сабаби эҳтимолӣ | Ҳалли |
|---|---|---|
| Display shows "HHHH" or "LLLL" | Sensor open circuit or short circuit; temperature exceeds range. | Check sensor wiring and connection. Verify sensor type matches setting. Ensure temperature is within range. |
| Контроллер гарм/хунук намекунад | Output wiring incorrect; SV not set correctly; PID parameters need tuning. | Check output wiring (SSR/Relay). Confirm SV is set to desired temperature. Perform auto-tuning if necessary. |
| Temperature fluctuates widely | PID parameters not optimized; sensor placement. | Perform auto-tuning. Ensure sensor is placed correctly and securely. |
| No display/Power issue | Не таъминоти барқ; ноқилҳои нодуруст. | Check power connections (terminals 8 & 9). Verify power source is active. |
