1. Introdução
The Selec CH-403-2 is a precision temperature chiller controller designed for industrial and commercial applications requiring accurate temperature regulation. This manual provides essential information for the safe and efficient installation, operation, and maintenance of your device. Please read this manual thoroughly before installation and operation.
2. Informações de segurança
Observe sempre as seguintes precauções de segurança para evitar ferimentos e danos ao dispositivo:
- Certifique-se de que a fonte de alimentação esteja desconectada antes de realizar qualquer fiação ou manutenção.
- A instalação e a manutenção devem ser realizadas somente por pessoal qualificado.
- Verifique se o volume da fonte de alimentaçãotage corresponde às especificações do controlador.
- Do not expose the controller to excessive moisture, dust, or corrosive gases.
- Garanta um aterramento adequado para evitar choque elétrico.
3. Configuração
3.1 Desembalagem
Carefully remove the controller from its packaging. Inspect the device for any signs of damage during transit. Report any damage to your supplier immediately.
3.2 Montagem
The CH-403-2 is designed for panel mounting. Cut an opening of 45mm x 45mm (1.77" x 1.77") in the panel. Insert the controller into the opening and secure it using the provided mounting clamps. Ensure a snug fit to prevent dust and moisture ingress.
3.3 Conexões de Fiação
Refer to the wiring diagram located on the side of the controller or in the detailed technical specifications. Ensure all connections are secure and correct before applying power.
- Fonte de energia: Connect the appropriate AC voltage (e.g., 230V AC) to the designated power terminals.
- Entrada do sensor: Connect the temperature sensor (e.g., NTC, PT100) to the sensor input terminals. Observe polarity if applicable.
- Saída de controle: Connect the chiller or heating element to the relay output terminals. Ensure the load current does not exceed the relay's maximum rating.
- Alarm Output (Optional): If applicable, connect external alarm devices to the alarm output terminals.
3.4 Inicialização
After all connections are verified, apply power to the controller. The display should illuminate, showing the current temperature and default settings.
4. Operação
4.1 Exibiçãoview
The front panel features a digital display showing the process value (PV) and set point (SV), along with indicator LEDs for output status (e.g., ON/OFF, Alarm).
4.2 Funções dos botões
- Botão de configuração: Utilizado para entrar no modo de configuração de parâmetros e confirmar as seleções.
- Botões PARA CIMA/PARA BAIXO: Used to navigate through parameters and adjust values.
- Botão MODE: Used to switch between display modes or access advanced settings.
4.3 Setting Temperature Setpoint (SV)
- Pressione o DEFINIR button once. The SV value will flash.
- Use o UP or ABAIXO buttons to adjust the setpoint to the desired temperature.
- Pressione o DEFINIR button again to confirm the new setpoint. The display will return to showing the PV.
4.4 Configuração de Parâmetros
To access advanced parameters such as hysteresis, calibration offset, or delay times, press and hold the DEFINIR button for several seconds until the first parameter code appears. Use the PARA CIMA/PARA BAIXO buttons to navigate through parameters and the DEFINIR button to select and modify values. Refer to the detailed parameter list in the full technical manual for specific codes and ranges.
5. Manutenção
5.1 Limpeza
Clean the front panel of the controller periodically with a soft, damp pano. Não utilize produtos de limpeza abrasivos ou solventes, pois estes podem danificar a tela ou o computador.asing. Ensure no liquid enters the device.
5.2 Verificações Regulares
- Inspecione as conexões da fiação para verificar se estão soltas ou corroídas.
- Verify the temperature sensor is clean and properly installed.
- Check for any unusual noises or smells from the controller or connected equipment.
5.3 Calibração
If temperature readings appear inaccurate, the sensor or controller may require calibration. Refer to the advanced parameter settings for sensor offset adjustment. For precise calibration, consult a qualified technician.
