4. Enstalasyon ak Enstalasyon
Avi Sekirite Enpòtan: 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 Dyagram fil elektrik
Refer to the following diagram for correct wiring connections. This model operates on DC 12V power supply.
Figi 3: Wiring diagram for the STC-1000 12V temperature controller. Connections are for power supply, NTC sensor, heating relay, and cooling relay.
- Tèminal 1 ak 2: Power Supply (DC 12V).
- Tèminal 3 ak 4: NTC Sensor connection.
- Tèminal 5 ak 6: Heating Relay Output (Connect to heating device).
- Tèminal 7 ak 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. Operasyon Enstriksyon
The STC-1000 operates in Celsius only. It cannot be switched to Fahrenheit.
5.1 Power On/Off
- Peze a Chanjman pouvwa button (marked with ⏻) to turn the controller on or off.
5.2 Ajisteman Paramèt Tanperati yo
The controller has two main temperature settings: the Set Temperature (ST) ak la Difference Temperature (DT), also known as hysteresis.
- Pou view the Set Temperature (ST): Yon ti tan peze la Setting (S) button. The display will show the current set temperature.
- To modify the Set Temperature (ST):
- Peze epi kenbe la Setting (S) bouton an pou apeprè 3 segonn jiskaske ekran an flache.
- Sèvi ak la LEVE (▲) or DESANN (▼) buttons to adjust the desired set temperature.
- Peze a Chanjman pouvwa button to save the setting and exit, or wait for 10 seconds for it to save automatically.
5.3 Advanced Parameter Settings (F1-F4)
To access and modify advanced parameters:
- Peze epi kenbe la Setting (S) bouton an pou apeprè 3 segonn jiskaske ekran an flache.
- Pandan ekran an ap flache, peze bouton an Setting (S) button again (do not hold) to cycle through parameters F1, F2, F3, F4.
- Sèvi ak la LEVE (▲) or DESANN (▼) buttons to adjust the value of the selected parameter.
- Peze a Chanjman pouvwa button to save the setting and exit, or wait for 10 seconds for it to save automatically.
| Paramèt | Deskripsyon | Range | Default |
|---|---|---|---|
| F1 | Difference Temperature (Hysteresis): The difference between the set temperature and the temperature at which the relay switches off. | 0.3 ° C a 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 | Kalibrasyon Tanperati: Adjusts the temperature reading to match a known accurate thermometer. | -10 ° C a 10 ° C | 0.0°C |
5.4 Mòd Chofaj ak Refwadisman
The STC-1000 automatically switches between heating and cooling based on the set temperature (ST) and difference temperature (DT).
- Mòd refwadisman: If the current temperature is higher than (ST + DT), the cooling relay activates. It deactivates when the temperature drops to ST.
- Mòd chofaj: If the current temperature is lower than (ST - DT), the heating relay activates. It deactivates when the temperature rises to ST.
6. Antretyen
- Netwayaj: Siye sifas kontwolè a avèk yon twal mou epi sèk. Pa sèvi ak pwodui netwayaj abrazif oswa solvan.
- Swen Capteur: Ensure the NTC sensor probe is clean and free from debris. While waterproof, avoid unnecessary physical damage to the probe or cable.
- Koneksyon: Periodically check wiring connections for tightness and signs of corrosion.
- Anviwònman: Operate the controller within the specified ambient temperature and humidity ranges to ensure optimal performance and lifespan.
NAN. Depanaj
| Pwoblèm | Kòz posib | Solisyon |
|---|---|---|
| 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). |
| Kontwolè pa limen | Pa gen ekipman pou kouran oswa vòltaj ki pa kòrèktage. | Check power connections and ensure DC 12V is supplied. |
| Chofaj/Refwadisman pa aktive | 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. |
