The use of any product will appear certain disadvantages, this is for the purposes of course is not an electromagnetic coil. For the electromagnetic coil trust we should not feel strange, this product in the industrial production use is appropriate. For the use of electromagnetic coil will bring great convenience to us, but if there is a disadvantage, then it will in constituting what is owed good effect, to repair the electromagnetic coil we want to attach.

1 test for electromagnetic coil voltage. In attracting coil of AC contactor in the voltage is 90% of the additional electromagnetic coil voltage, so that the electromagnetic coil is normal operation, does not need to worry too much.

2. In the use of electromagnetic coil, need to check without overheating, if aging, or discolor overheating of the outside would appear, if appear the situation and perhaps because of the short circuit noise of the ramp, at this time need to be replaced to prevent accidents as.

3 for the wire and wire for the electromagnetic coil is also need to check, see if there is a welding or disconnection, if there is a freak appear must be timely repair.

It is very important for the accurate repair of the electromagnetic coil, so that it can reduce the appearance of the faults and prevent damage..
