4. Kurulum ve Kurulum
Önemli Güvenlik Bildirimi: Installation should be performed by qualified personnel. Ensure power is disconnected before wiring to prevent electric shock. Strictly distinguish between power supply, sensor, and relay interfaces. Maintain proper distance between sensor down-lead and power wires to avoid interference.
4.1 Kablolama Şeması
Refer to the following diagram for correct wiring connections. This model operates on DC 12V power supply.
Şekil 3: Wiring diagram for the STC-1000 12V temperature controller. Connections are for power supply, NTC sensor, heating relay, and cooling relay.
- Terminal 1 ve 2: Power Supply (DC 12V).
- Terminal 3 ve 4: NTC Sensor connection.
- Terminal 5 ve 6: Heating Relay Output (Connect to heating device).
- Terminal 7 ve 8: Cooling Relay Output (Connect to cooling device).
Ensure all connections are secure and insulated. Verify the power supply voltage matches the controller's requirement (DC 12V for this model).
4.2 Montaj
The STC-1000 is designed for panel mounting. Cut an opening of 71mm x 29mm in your panel. Insert the controller and secure it using the provided clips or mounting brackets.
5. Kullanım Talimatları
The STC-1000 operates in Celsius only. It cannot be switched to Fahrenheit.
5.1 Güç Açma/Kapatma
- Basın Güç Anahtarı button (marked with ⏻) to turn the controller on or off.
5.2 Sıcaklık Parametrelerinin Ayarlanması
The controller has two main temperature settings: the Set Temperature (ST) ve Difference Temperature (DT), also known as hysteresis.
- İle view the Set Temperature (ST): Kısaca basın Setting (S) Düğmeye basın. Ekran, ayarlanmış mevcut sıcaklığı gösterecektir.
- To modify the Set Temperature (ST):
- Basılı tutun Setting (S) button for approximately 3 seconds until the display flashes.
- Kullanın YUKARI (▲) or AŞAĞI (▼) buttons to adjust the desired set temperature.
- Basın Güç Anahtarı button to save the setting and exit, or wait for 10 seconds for it to save automatically.
5.3 Advanced Parameter Settings (F1-F4)
Gelişmiş parametrelere erişmek ve bunları değiştirmek için:
- Basılı tutun Setting (S) button for approximately 3 seconds until the display flashes.
- Ekran yanıp sönerken, tuşuna basın. Setting (S) button again (do not hold) to cycle through parameters F1, F2, F3, F4.
- Kullanın YUKARI (▲) or AŞAĞI (▼) Seçilen parametrenin değerini ayarlamak için düğmeler.
- Basın Güç Anahtarı button to save the setting and exit, or wait for 10 seconds for it to save automatically.
| Parametre | Tanım | Menzil | Varsayılan |
|---|---|---|---|
| F1 | Difference Temperature (Hysteresis): The difference between the set temperature and the temperature at which the relay switches off. | 0.3°C ila 10°C | 2.0°C |
| F2 | Highest Set Point Limit: Limits the maximum adjustable set temperature. | Set Temp to 110°C | 110°C |
| F3 | Lowest Set Point Limit: Limits the minimum adjustable set temperature. | -50°C to Set Temp | -50°C |
| F4 | Sıcaklık Kalibrasyonu: Adjusts the temperature reading to match a known accurate thermometer. | -10°C ila 10°C | 0.0°C |
5.4 Heating and Cooling Modes
The STC-1000 automatically switches between heating and cooling based on the set temperature (ST) and difference temperature (DT).
- Soğutma Modu: If the current temperature is higher than (ST + DT), the cooling relay activates. It deactivates when the temperature drops to ST.
- Isıtma Modu: If the current temperature is lower than (ST - DT), the heating relay activates. It deactivates when the temperature rises to ST.
6. Bakım
- Temizlik: Wipe the controller's surface with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Sensör Bakımı: Ensure the NTC sensor probe is clean and free from debris. While waterproof, avoid unnecessary physical damage to the probe or cable.
- Bağlantılar: Periodically check wiring connections for tightness and signs of corrosion.
- Çevre: Operate the controller within the specified ambient temperature and humidity ranges to ensure optimal performance and lifespan.
7. Sorun Giderme
| Sorun | Olası Neden | Çözüm |
|---|---|---|
| Display shows "EE" | Sensor error or open circuit. | Check sensor connection. Replace sensor if damaged. |
| Display shows "HHH" | Temperature exceeds upper limit of measurement range. | Ensure the environment temperature is within the sensor's range (-50°C to 99°C). |
| Display shows "LLL" | Temperature falls below lower limit of measurement range. | Ensure the environment temperature is within the sensor's range (-50°C to 99°C). |
| Denetleyici açılmıyor | Güç kaynağı yok veya yanlış voltajtage. | Check power connections and ensure DC 12V is supplied. |
| Heating/Cooling not activating | Incorrect temperature settings (ST, DT), wiring error, or device malfunction. | Verify ST and DT settings. Check heating/cooling device wiring. Ensure the device is within operating parameters. |
