1. Introduction
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. Consignes de sécurité
Respectez toujours les consignes de sécurité suivantes afin d'éviter les blessures et les dommages à l'appareil :
- Assurez-vous que l'alimentation électrique est débranchée avant d'effectuer tout câblage ou opération de maintenance.
- L'installation et l'entretien doivent être effectués uniquement par du personnel qualifié.
- Vérifiez que le volume d'alimentationtage matches the specifications of the controller.
- Do not expose the controller to excessive moisture, dust, or corrosive gases.
- Assurez-vous d’une mise à la terre appropriée pour éviter les chocs électriques.
3. Installation
3.1 Déballage
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 Montage
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 câblage
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.
- Alimentation: Connect the appropriate AC voltage (e.g., 230V AC) to the designated power terminals.
- Entrée capteur: Connect the temperature sensor (e.g., NTC, PT100) to the sensor input terminals. Observe polarity if applicable.
- Sortie de contrôle: Connect the chiller or heating element to the relay output terminals. Ensure the load current does not exceed the relay's maximum rating.
- Sortie d'alarme (optionnelle) : If applicable, connect external alarm devices to the alarm output terminals.
3.4 Mise sous tension initiale
After all connections are verified, apply power to the controller. The display should illuminate, showing the current temperature and default settings.
4. Fonctionnement
4.1 Affichage terminéview
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 Fonctions des boutons
- Bouton de réglage: Permet d'accéder au mode de paramétrage et de confirmer les sélections.
- Boutons HAUT/BAS : Permet de naviguer dans les paramètres et d'ajuster les valeurs.
- Bouton MODE : Used to switch between display modes or access advanced settings.
4.3 Setting Temperature Setpoint (SV)
- Appuyez sur le ENSEMBLE button once. The SV value will flash.
- Utilisez le UP or VERS LE BAS buttons to adjust the setpoint to the desired temperature.
- Appuyez sur le ENSEMBLE button again to confirm the new setpoint. The display will return to showing the PV.
4.4 Configuration des paramètres
To access advanced parameters such as hysteresis, calibration offset, or delay times, press and hold the ENSEMBLE Appuyez sur le bouton pendant plusieurs secondes jusqu'à ce que le premier code de paramètre apparaisse. Utilisez le HAUT/BAS buttons to navigate through parameters and the ENSEMBLE button to select and modify values. Refer to the detailed parameter list in the full technical manual for specific codes and ranges.
5. Entretien
5.1 Nettoyage
Clean the front panel of the controller periodically with a soft, damp chiffon. N’utilisez pas de nettoyants abrasifs ni de solvants, car ils peuvent endommager l’écran ou le câble.asing. S'assurer qu'aucun liquide ne pénètre dans l'appareil.
5.2 Contrôles réguliers
- Vérifiez que les connexions électriques ne sont pas desserrées ou corrodées.
- Verify the temperature sensor is clean and properly installed.
- Check for any unusual noises or smells from the controller or connected equipment.
5.3 Étalonnage
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.
