1. Introducció
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. Informació de seguretat
Observeu sempre les següents precaucions de seguretat per evitar lesions i danys al dispositiu:
- Assegureu-vos que el subministrament elèctric estigui desconnectat abans de realitzar qualsevol cablejat o manteniment.
- La instal·lació i el manteniment només els ha de dur a terme personal qualificat.
- Comproveu que la font d'alimentació voltage matches the specifications of the controller.
- Do not expose the controller to excessive moisture, dust, or corrosive gases.
- Assegureu-vos de posar a terra correctament per evitar descàrregues elèctriques.
3. Configuració
3.1 Desembalatge
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 Muntatge
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 Connexions de cablejat
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.
- Font d'alimentació: Connect the appropriate AC voltage (e.g., 230V AC) to the designated power terminals.
- Entrada del sensor: Connect the temperature sensor (e.g., NTC, PT100) to the sensor input terminals. Observe polarity if applicable.
- Sortida de control: Connect the chiller or heating element to the relay output terminals. Ensure the load current does not exceed the relay's maximum rating.
- Sortida d'alarma (opcional): If applicable, connect external alarm devices to the alarm output terminals.
3.4 Engegada inicial
After all connections are verified, apply power to the controller. The display should illuminate, showing the current temperature and default settings.
4. Funcionament
4.1 Mostra finalview
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 Funcions dels botons
- Botó SET: S'utilitza per entrar al mode de configuració de paràmetres i confirmar les seleccions.
- Botons UP/DOWN: S'utilitza per navegar pels paràmetres i ajustar els valors.
- Botó MODE: Used to switch between display modes or access advanced settings.
4.3 Setting Temperature Setpoint (SV)
- Premeu el botó SET button once. The SV value will flash.
- Utilitza el UP or ABAIX buttons to adjust the setpoint to the desired temperature.
- Premeu el botó SET button again to confirm the new setpoint. The display will return to showing the PV.
4.4 Configuració de paràmetres
To access advanced parameters such as hysteresis, calibration offset, or delay times, press and hold the SET button for several seconds until the first parameter code appears. Use the Amunt/Avall buttons to navigate through parameters and the SET button to select and modify values. Refer to the detailed parameter list in the full technical manual for specific codes and ranges.
5. Manteniment
5.1 Neteja
Clean the front panel of the controller periodically with a soft, damp drap. No utilitzeu productes de neteja abrasius ni dissolvents, ja que poden danyar la pantalla o laasing. Ensure no liquid enters the device.
5.2 Comprovacions periòdiques
- Inspeccioneu les connexions del cablejat per detectar si hi ha fluïdesa o corrosió.
- Verify the temperature sensor is clean and properly installed.
- Check for any unusual noises or smells from the controller or connected equipment.
5.3 Calibració
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.
