Wiring Key Points:
- Fonte de energia: Connect 230V AC to the designated terminals.
- Sensores: Connect the two temperature sensors (S1, S2) to their respective terminals.
- Saídas de relé: Connect the compressor, fan, and auxiliary loads to their corresponding relay terminals. The diagram specifies maximum current ratings for each output (e.g., COOL: 12(9)A 250V~, FAN: 5(4)A 250V~, AUX: 8(4)A 250V~).
- Entradas Digitais: Utilize terminals for programmable digital inputs such as door switches or external alarms.
4.3 Inicialização
After wiring, apply power to the controller. The display should illuminate, showing the current temperature or an initial setup prompt.
5. Instruções de operação
The AKO D-14323 offers various programmable parameters to suit different refrigeration needs.
5.1 Operação básica
- Exibição de temperatura: The main display shows the current temperature measured by the primary sensor.
- Botão de configuração: Pressione para view or modify the setpoint temperature. Hold to enter parameter programming mode.
- Botão ESC: Used to exit menus or cancel changes.
- Setas para cima/baixo: Used to adjust values in programming mode or manually initiate defrost (if configured).
- Botão de energia: Turns the unit on/off or acts as a reset in some configurations.
5.2 Definindo o ponto de ajuste da temperatura
- Pressione o DEFINIR button briefly. The current setpoint will flash.
- Use o Up or Abaixo Botões de seta para ajustar a temperatura desejada.
- Imprensa DEFINIR again to confirm and save the new setpoint, or ESC para sair sem salvar.
5.3 Advanced Parameter Programming
To access advanced parameters (e.g., defrost cycles, differential, auxiliary relay functions), hold the DEFINIR button for several seconds until the first parameter code appears. Navigate using the arrow buttons and press DEFINIR to enter/confirm values. Refer to the detailed programming guide (usually provided separately or available from AKO) for a complete list of parameters and their functions.
5.4 Defrost Cycle Management
The controller supports various defrost methods, including controlling the compressor, resistance heaters, or fans. Defrost parameters can be adjusted to optimize performance based on the application. An optional probe allows defrosting by temperature.
6. Manutenção
Regular maintenance ensures optimal performance and extends the lifespan of your temperature controller.
- Limpeza: Limpe periodicamente o painel frontal com um pano macio e seco.amp pano. Não use produtos de limpeza abrasivos ou solventes.
- Inspeções: Regularly check wiring connections for tightness and signs of wear or corrosion.
- Verificação do sensor: Ensure temperature sensors are securely in place and free from damage.
For any internal maintenance or repairs, contact a qualified technician.
7. Solução De Problemas
If you encounter issues with your AKO D-14323 controller, refer to the following common problems and solutions:
| Problema | Possível causa | Solução |
|---|---|---|
| Display está em branco | Sem fonte de alimentação; fiação incorreta | Check power connections and ensure 230V supply. Verify wiring according to the diagram. |
| Leitura incorreta de temperatura | Faulty sensor; sensor not properly connected or placed | Check sensor connections. Replace sensor if damaged. Ensure sensor is correctly positioned in the controlled environment. |
