3. Орнотуу боюнча көрсөтмөлөр

Proper installation is crucial for the safe and effective operation of the STC-100A temperature controller. Ensure all electrical connections are made by a qualified professional if you are unsure.

3.1 Физикалык орнотуу

1. Prepare an opening in your control panel or enclosure with dimensions matching the 'Installing Hole Size' (71mm L x 29mm W).
2. Insert the STC-100A controller into the prepared opening.
3. Secure the controller using the provided mounting clips or screws to ensure it is firmly in place.
4. Connect the NTC temperature sensor probe to the designated terminals on the controller. Ensure the sensor is placed in the area where temperature measurement is required. The sensor wire length is 2 meters.

3.2 Электр зымдары

Эскертүү: Disconnect power before performing any wiring to prevent electric shock. All wiring should comply with local electrical codes.

• Connect the power supply (220VAC, 50/60Hz) to the designated power input terminals on the controller.
• Connect your heating or refrigerating load (e.g., compressor, heater) to the relay output terminals. The relay output capacity is 10A (0.5HP) at 220VAC.
• Double-check all connections for tightness and correct polarity before applying power.

4. Иштетүү жана дисплей панели

The STC-100A features a two-digit LED display that shows the current temperature value and other operational information. Control is managed via three buttons located below the display.

4.1 Баскыч функциялары

• Жогорку баскыч (▲): Маанилерди жогорулатуу же менюларда өйдө багыттоо үчүн колдонулат.
• Төмөн баскычы (▼): Маанилерди азайтуу же менюларда ылдый багыттоо үчүн колдонулат.
• Set Key (SET): Used to enter parameter setting mode, confirm selections, or save changes.

5. Иштөө нускамалары

5.1 Күйгүзүү/өчүрүү

The controller powers on automatically when connected to a suitable power supply. There is no dedicated power button.

5.2 Setting the Temperature Value

1. басыңыз SET key once. The display will flash, indicating that the temperature setting value can be adjusted.
2. колдонуу Өйдө (▲) or Төмөн (▼) keys to adjust the desired temperature set point.
3. басыңыз SET key again to confirm and save the new setting. The display will stop flashing and return to showing the current temperature.

5.3 Adjusting Advanced Parameters

To access and modify advanced parameters (e.g., difference value, delay protection, temperature calibration), refer to the detailed parameter list in the full manual. Typically, this involves pressing and holding the SET key for several seconds to enter the parameter menu, then using the Өйдө (▲) жана Төмөн (▼) keys to navigate and adjust values, and SET ырастоо үчүн.

6. Техникалык тейлөө

Regular maintenance ensures the longevity and accuracy of your temperature controller.

• Тазалоо: Дисплейди мезгил-мезгили менен сүртүп туруңуз жанаasing with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure no liquids enter the device.
• Сенсорго кам көрүү: Ensure the temperature sensor probe is clean and free from debris. Avoid bending or damaging the sensor wire. If the sensor appears damaged or provides inconsistent readings, it may need replacement.
• Экологиялык шарттар: Operate the controller within the specified operating temperature (0°C to +60°C) and relative humidity (+20% to +85%, non-condensing) to prevent damage.

7. Кыйынчылыктарды

This section addresses common issues you might encounter with the STC-100A controller.

7.1 Sensor Error Alarm

• Белги: The display shows an error code (e.g., 'E1' or similar, as indicated by 'Alarm when sensor error' in main functions).
• Мүмкүн болгон себеп: The NTC sensor is disconnected, damaged, or faulty.
• Чечим: Check the sensor's connection to the controller. Ensure the wire is not cut or shorted. If the connection is secure and the error persists, replace the sensor. The delay time when sensor error is 1 minute before an alarm is triggered.

7.2 Температуранын туура эмес көрсөткүчтөрү

• Мүмкүн болгон себеп: Sensor misplacement, environmental interference, or calibration offset.
• Чечим: Ensure the sensor is correctly positioned to measure the desired temperature. Check for drafts or heat sources directly affecting the sensor. If necessary, use the temperature calibration function (refer to advanced parameters) to adjust the reading.

7.3 Controller Not Powering On

• Мүмкүн болгон себеп: Электр менен камсыздоо жок, үн туура эмесtage, or faulty wiring.
• Чечим: Verify that the 220VAC power supply is connected and active. Check all wiring connections for security and correctness. Ensure the voltage is within the specified range (220VAC +10% -15%).

8. Коопсуздук маалыматы

• Always disconnect power before installing, wiring, or performing maintenance on the controller.
• Ensure all wiring is done by a qualified person and complies with local electrical codes and regulations.
• Do not operate the device in environments exceeding its specified operating temperature or humidity ranges.
