Although this is not a common problem of AC contactors, the failure of AC contactors to engage will affect the efficiency of operation and even damage the production equipment.
What if the solenoid coil causes a pick-up problem? Delixi Electric teaches you to test, if the test results are the existence of additional voltage, but the additional voltage and the parameter specification of the electromagnetic coil has a certain gap, generally means that the electromagnetic coil may present a problem, if the additional voltage exists, and the same parameter specification as the low-voltage AC contactor, it is roughly the problem caused by the electromagnetic coil, and the electromagnetic coil may need to be replaced to be able to deal with the suction problem.
What should I do if the control loop causes a problem with engagement? Under normal circumstances, when looking for a problem with low-voltage AC contactor equipment, you need to prepare corresponding things, and the homework you need to do is to test both sides of the electromagnetic coil, if the test result is that there is no additional voltage, it means that the cause of the problem is closely related to the control loop, and you can check whether the control loop presents a problem. Problems with the control circuit and solenoid coil often lead to problems with the engagement of low-voltage AC contactors, so it is important to always check the components of the equipment and perform excellent maintenance work on the low-voltage AC contactors.
To sum up, if the Delixi AC contactor is unable to suck the situation, comprehensively check from the following conditions:
1. The contactor coil is broken
2. Check whether the power supply voltage reaches more than 85% of the additional voltage, which is the minimum requirement for the contactor coil suction voltage
3. Check whether the applicable voltage level of the contactor coil corresponds to the power supply, and see whether the voltage is 220V or 380V
4. Check whether the power supply is AC or DC
5. Check whether the power switch is turned on and whether the starting circuit is open
