Tips: Iron core of the contactor can't suck up, how to solve?
Possible causes of the fault:

• Low power supply voltage.
• Something is wrong with the contactor's control loop or the power supply can't be connected.
• Contactor coil is broken or burned.
• The contactor magnet is partly inflexible or the moving contact gets stuck.
• Pressure of the contact spring is too large.

Maintenance method:

1. If there's a huge difference between the measured value and the coil's rated voltage, look up the reason from the power supply and adjust the voltage to the normal value.
2. Correct the contactor's control loop and connect it by the correct line; replaced the damaged electrical components.
3. Measure the coil resistance with a multimeter, if the current is too large, the coil shorts or breaks, please replace the coil.
4. Repair the mechanical fault of the contactor, remove the rusty part, add some lubricating oil to the movement mechanism; replaced the damaged electrical components.
5. Adjust the contact spring pressure according to technical requirements.
