- 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. Wskazówki użytkownika
