1. Sarrera
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. Segurtasun informazioa
Bete beti segurtasun neurri hauek gailuari lesioak eta kalteak saihesteko:
- Ziurtatu energia-iturria deskonektatuta dagoela kableatu edo mantentze-lanak egin aurretik.
- Instalazioa eta mantentze-lanak langile kualifikatuek bakarrik egin behar dituzte.
- Egiaztatu elikadura hornidura boltage matches the specifications of the controller.
- Do not expose the controller to excessive moisture, dust, or corrosive gases.
- Ziurtatu lurra egokia deskarga elektrikoa saihesteko.
3. Konfigurazioa
3.1 Paketatzea
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 Muntaketa
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 Kableatutako konexioak
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.
- Elikatze-iturria: Connect the appropriate AC voltage (e.g., 230V AC) to the designated power terminals.
- Sentsore sarrera: Connect the temperature sensor (e.g., NTC, PT100) to the sensor input terminals. Observe polarity if applicable.
- Kontrol-irteera: 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 Hasierako piztea
After all connections are verified, apply power to the controller. The display should illuminate, showing the current temperature and default settings.
4. Funtzionamendua
4.1 Bistaratuview
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 Botoien funtzioak
- SET botoia: Used to enter parameter setting mode and confirm selections.
- GORA/BEHERA botoiak: Used to navigate through parameters and adjust values.
- MODE botoia: Used to switch between display modes or access advanced settings.
4.3 Setting Temperature Setpoint (SV)
- Sakatu EZARTU button once. The SV value will flash.
- Erabili UP or BEHERA buttons to adjust the setpoint to the desired temperature.
- Sakatu EZARTU button again to confirm the new setpoint. The display will return to showing the PV.
4.4 Parametroen konfigurazioa
To access advanced parameters such as hysteresis, calibration offset, or delay times, press and hold the EZARTU button for several seconds until the first parameter code appears. Use the GORA/BEHERA buttons to navigate through parameters and the EZARTU button to select and modify values. Refer to the detailed parameter list in the full technical manual for specific codes and ranges.
5. Mantentzea
5.1 Garbiketa
Clean the front panel of the controller periodically with a soft, damp oihal. Ez erabili garbitzaile edo disolbatzaile urratzailerik, hauek pantaila edo c kaltetu baitezakete.asing. Ziurtatu ez dela likidorik sartzen gailuan.
5.2 Ohiko egiaztapenak
- Egiaztatu kableatu-konexioak solteak edo korrosiorik dauden ikusteko.
- Verify the temperature sensor is clean and properly installed.
- Check for any unusual noises or smells from the controller or connected equipment.
5.3 Kalibrazioa
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.
