4. Інструкція з експлуатації
Once correctly installed and wired, the GEYA GYHC modular contactor operates by receiving a control voltage (DC12V or DC24V) to its coil, which then switches the main power circuit (AC220V-240V) to connected loads.
- Вікно індикатора: The contactor is equipped with an indicator window that visually displays its on/off state.
- Застосування: This contactor is ideal for controlling various household and commercial loads, including lighting circuits, heating elements, ventilation fans, motorized curtains, and other low inductive loads.
5. Технічне обслуговування
The GEYA GYHC modular contactor is designed for long-term, reliable operation with minimal maintenance. However, regular checks can help ensure optimal performance and safety.

- Прибирання: If necessary, gently clean the exterior of the contactor with a dry, soft cloth. Do not use liquids or abrasive cleaners.
Завжди відключайте живлення перед проведенням будь-якої перевірки або технічного обслуговування.
6. Вирішення проблем
Якщо контактор не працює належним чином, зверніть увагу на такі поширені проблеми:
- Contactor Not Engaging:
- Check if the correct control voltage (DC12V or DC24V) is being supplied to the coil terminals (A1/A2).
- Verify that the control circuit is complete and there are no breaks in the wiring.
- Ensure the main power supply to the contactor is active.
- Contactor Overheating:
- Check for loose wiring connections, which can cause resistance and heat buildup.
- Ensure the load current does not exceed the contactor's rated current (25A for this model).
- Verify that the ambient operating temperature is within the specified range (-5°C to +60°C) and there is adequate ventilation.
- Indicator Window Not Showing State:
- This may indicate a mechanical failure or an issue with the coil engagement. Check the control voltage and listen for the audible click of the contactor engaging.
For complex issues or if you are unsure, consult a qualified electrician.
7. Поради користувача
- Правильний розмір: Always ensure the contactor's current rating (e.g., 25A) is appropriate for the connected load to prevent overloading.
- Coil Voltage Матч: Double-check that the control voltage supplied to the contactor coil (DC12V or DC24V) precisely matches the contactor's specification to avoid damage.
- Чітке маркування: Utilize the transparent flip cover design to insert clear labels for each circuit controlled by the contactor, aiding in future maintenance and troubleshooting.
- Професійна установка: For safety and optimal performance, it is highly recommended to have the contactor installed by a certified electrician.
