Use of any product will be some failures, which the electromagnetic coil is no exception. Solenoid believe that people should not feel strange, in the industrial production of the product is very important. For the use of the electromagnetic coil it will bring great convenience, but if one fails, it will become a negative impact on the electromagnetic coil, maintenance attention.

Correct repair method electromagnetic inductance of the coil:

1, the voltage necessary to detect the electromagnetic coil. AC contactor solenoid pull-in coil voltage 90% of rated voltage, solenoid, work, do not need to worry too much.

2, the use of an electromagnetic coil, you need to check whether overheating, if the external thermal aging or discoloration occur, if this happens, noise may be due to short-circuit the ramp needs to be replaced to prevent accidents.

3, the lead member and the rubbing line solenoid also need to check to see if there are open welding or disconnected if there is an exception must be promptly repaired.

4, the appropriate solenoid maintenance is very important, it can reduce the failure to avoid damage.
