7. Muammolarni bartaraf qilish; nosozliklarni TUZATISH
| Muammo | Mumkin sabab | Yechim |
|---|---|---|
| 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. |
| Controller not heating/cooling | 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. |
| Harorat keng o'zgarib turadi | PID parameters not optimized; sensor placement. | Perform auto-tuning. Ensure sensor is placed correctly and securely. |
| No display/Power issue | Elektr ta'minoti yo'q; noto'g'ri simlar. | Check power connections (terminals 8 & 9). Verify power source is active. |
