5. Instruções de operação
5.1 Exibiçãoview
The MC701 features a dual display:
- PV (Process Value): Displays the current measured temperature.
- SV (Set Value): Displays the desired target temperature.
Luzes indicadoras:
- OUT: Indicates output status (heating/cooling).
- AT: Auto-tuning indicator.
- ALM1, ALM2: Alarm indicators.
5.2 Funções dos botões
- 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 Setting the Target Temperature (SV)
- Pressione o DEFINIR Pressione o botão uma vez. O visor SV começará a piscar.
- Use o ^ e V botões para ajustar a temperatura desejada.
- Use o < button to shift the cursor for faster adjustment.
- Imprensa DEFINIR again to confirm the new SV and exit the setting mode.
5.4 Advanced Parameter Settings
To access advanced parameters (e.g., PID parameters, alarm settings, input type, temperature unit), press and hold the DEFINIR button for several seconds until the first parameter code appears on the PV display.
- Usar ^ e V to navigate through parameters.
- Imprensa DEFINIR para view or edit a parameter's value.
- Ajuste o valor usando ^, V, e <.
- Imprensa DEFINIR to save the value and return to the parameter list.
- To exit advanced settings, press and hold DEFINIR again, or wait for a timeout.
6. Manutenção
Regular maintenance ensures the longevity and optimal performance of your MC701 controller.
- Cleaning: Wipe the display and casinLimpe com um pano macio e seco. Não utilize produtos de limpeza abrasivos ou solventes.
- 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. Solução De Problemas
| Problema | Possível causa | Solução |
|---|---|---|
| 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. |
| A temperatura varia bastante. | PID parameters not optimized; sensor placement. | Perform auto-tuning. Ensure sensor is placed correctly and securely. |
| Sem problema de exibição/energia | Sem fonte de alimentação; fiação incorreta. | Check power connections (terminals 8 & 9). Verify power source is active. |
