- SV (Set Value): Displays the desired target temperature.
Indicatoare luminoase:
- OUT: Indicates output status (heating/cooling).
- AT: Auto-tuning indicator.
- ALM1, ALM2: Alarm indicators.
5.2 Funcțiile butoanelor
- SET: Enters parameter setting mode or confirms a setting.
- < (R/S): Shifts cursor during setting, or resets alarm.
- V (Down Arrow): Decreases value during setting.
- ^ (Up Arrow): Increases value during setting.
5.3 Setarea temperaturii țintă (SV)
- Apăsați tasta SET Apăsați butonul o dată. Afișajul SV va începe să clipească.
- Utilizați ^ şi V butoane pentru a regla temperatura dorită.
- Utilizați < pentru a deplasa cursorul și a realiza o ajustare mai rapidă.
- Presa SET again to confirm the new SV and exit the setting mode.
5.4 Setări avansate ale parametrilor
To access advanced parameters (e.g., PID parameters, alarm settings, input type, temperature unit), press and hold the SET button for several seconds until the first parameter code appears on the PV display.
- Utilizare ^ şi V to navigate through parameters.
- Presa SET la view or edit a parameter's value.
- Ajustați valoarea utilizând ^, V, și <.
- Presa SET to save the value and return to the parameter list.
- To exit advanced settings, press and hold SET again, or wait for a timeout.
6. Întreținere
Regular maintenance ensures the longevity and optimal performance of your MC701 controller.
- Cleaning: Wipe the display and casinȘtergeți cu o cârpă moale și uscată. Nu utilizați substanțe de curățare abrazive sau solvenți.
- Ventilation: Ensure the ventilation slots on the sides of the unit are not obstructed to prevent overheating.
- Connections: Periodically check all wiring connections for tightness and signs of wear or corrosion.
- Storage: If storing the unit, keep it in a dry, dust-free environment within its specified operating temperature range.
7. Depanare
| Problemă | Cauza posibila | Soluţie |
|---|---|---|
| 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. |
| Temperatura fluctuează foarte mult | PID parameters not optimized; sensor placement. | Perform auto-tuning. Ensure sensor is placed correctly and securely. |
| No display/Power issue | Fără alimentare cu energie electrică; cablare incorectă. | Check power connections (terminals 8 & 9). Verify power source is active. |
