Проблемаларды чечүү
If you encounter issues with your STC-3008 controller, refer to the following common problems and their solutions.
| Көйгөй | Мүмкүн себеп | Чечим |
|---|---|---|
| Дисплейде "LLL" же "HHH" көрсөтүлөт | Sensor error or temperature out of range. | Check sensor connection. Ensure sensor is within the operating temperature range (-50°C to 70°C). Replace sensor if damaged. |
| Controller not turning device on/off | Incorrect temperature settings, wiring issue, or device malfunction. | Verify start and stop temperature settings. Check all wiring connections for looseness or incorrect placement. Test the connected device independently. |
| Температураны туура эмес окуу | Sensor placement, interference, or sensor calibration. | Ensure sensor is placed correctly and not exposed to direct heat/cold sources that don't reflect the desired measurement area. Check for electromagnetic interference. While the unit is factory calibrated, significant discrepancies might indicate a faulty sensor. |
| Дисплей/кубат берүү көйгөйү жок | Электр энергиясы жок же зымдары бузулган. | Check power source and ensure it matches the controller's voltage (12V/24V/110V-220VAC). Verify power supply wiring to terminals 1 and 2. |
Техникалык тейлөө
To ensure the longevity and optimal performance of your Walfront STC-3008 temperature controller, follow these maintenance guidelines:
- Тазалоо: Дисплейди үзгүлтүксүз сүртүп,asing with a soft, dry cloth. Avoid using abrasive cleaners or solvents that could damage the plastic.
- Экологиялык шарттар: Ensure the controller is operated within the specified ambient temperature (0~60°C) and humidity (20%~85% non-condensing) ranges.
- Сенсорго кам көрүү: Keep the temperature sensor clean and free from debris. Avoid bending or damaging the sensor cable.
- Туташуу текшерүүлөрү: Бардык зымдардын туташууларынын бекем жана дат баспагандыгын текшерүү үчүн мезгил-мезгили менен текшерип туруңуз.
- Вентиляция: Ашыкча ысып кетүүнүн алдын алуу үчүн, айрыкча жабык мейкиндикте орнотулган болсо, түзмөктүн айланасында жетиштүү желдетүүнү камсыз кылыңыз.
