1. Uvod
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. Varnostne informacije
Vedno upoštevajte naslednje varnostne ukrepe, da preprečite poškodbe in škodo na napravi:
- Pred kakršnim koli ožičenjem ali vzdrževanjem se prepričajte, da je napajanje odklopljeno.
- Namestitev in servisiranje naj izvaja samo usposobljeno osebje.
- Preverite, ali je voltage se ujema s specifikacijami krmilnika.
- Do not expose the controller to excessive moisture, dust, or corrosive gases.
- Poskrbite za pravilno ozemljitev, da preprečite električni udar.
3. Nastavitev
3.1 Razpakiranje
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 Montaža
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 Žične povezave
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.
- Napajanje: Connect the appropriate AC voltage (e.g., 230V AC) to the designated power terminals.
- Vhod senzorja: Connect the temperature sensor (e.g., NTC, PT100) to the sensor input terminals. Observe polarity if applicable.
- Izhod krmiljenja: 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 Začetni vklop
After all connections are verified, apply power to the controller. The display should illuminate, showing the current temperature and default settings.
4. Delovanje
4.1 Prikaz končanview
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 Funkcije gumbov
- Gumb SET: Uporablja se za vstop v način nastavitve parametrov in potrditev izbir.
- Gumba GOR/DOL: Uporablja se za navigacijo po parametrih in prilagajanje vrednosti.
- Gumb MODE: Used to switch between display modes or access advanced settings.
4.3 Setting Temperature Setpoint (SV)
- Pritisnite NASTAVI button once. The SV value will flash.
- Uporabite UP or DOL buttons to adjust the setpoint to the desired temperature.
- Pritisnite NASTAVI button again to confirm the new setpoint. The display will return to showing the PV.
4.4 Konfiguracija parametrov
To access advanced parameters such as hysteresis, calibration offset, or delay times, press and hold the NASTAVI button for several seconds until the first parameter code appears. Use the GOR/DOL buttons to navigate through parameters and the NASTAVI button to select and modify values. Refer to the detailed parameter list in the full technical manual for specific codes and ranges.
5. Vzdrževanje
5.1 Čiščenje
Clean the front panel of the controller periodically with a soft, damp krpo. Ne uporabljajte abrazivnih čistil ali topil, saj lahko poškodujejo zaslon aliasing. Ensure no liquid enters the device.
5.2 Redni pregledi
- Preverite ožičene povezave glede ohlapnosti ali korozije.
- Verify the temperature sensor is clean and properly installed.
- Check for any unusual noises or smells from the controller or connected equipment.
5.3 Kalibracija
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.
