What is the reason why the contactor of the air curtain cabinet does not engage?

What is the reason why parents refuse to suction at the base, I think the reason why parents refuse to dissuade is that there are too many ordinary dreams, or he doesn't.

This may be that the combiner in this motherboard is not engaged, so this situation will occur, change the motherboard today.

The reason why the air curtain cabinet contactor does not engage may be that the connection place where he is not installed is good, of course, you can also consult the after-sales service.

Oh, it may be that contactor of his is broken, so please find someone to repair it quickly, otherwise it will easily break down.

Now the maple is so expensive that it does not come into contact with it, I think it should still be set for the reason, we can still readjust, so that we can bring a better one.

The contactor does not engage most of the contactor itself coil does not get the power supply voltage, and the coil is broken or armature jamming is very rare, when judging the working voltage of the contactor coil with a multimeter, continue to find the relevant circuits of the coil power supply when there is no voltage, such as: coil power supply, button, interlock button related to coil power supply, auxiliary normally open and normally closed contacts of interlock contactor, thermal relay contact, timer contact--- etc. Finally, find the fault point that the coil cannot be powered by power. (Of course, if the coil does not engage with voltage, it can be replaced directly).

A lot of times live to see the live operation, remember that you are not difficult, here very. It's not easy to say clearly, what to ask specifically, I said it in detail, help you find a way.

The reason why the air curtain cabinet contactor does not engage is probably that the electromagnetic system should not be very effective.

It may be a contactor, the coil is burned out, you can change a contactor to see if it can be.

The AC contactor of Fengmu cabinet can be used for a new one, and it will not be shut down again.

Test whether there is rated voltage at both ends of the solenoid coil, if there is no voltage, it means that the control loop is faulty, and it should be checked and processed according to the circuit; If there is a standby voltage, but it is lower than the rated voltage of the coil, the electromagnetic force generated by the electromagnetic coil after energizing is not enough to overcome the reaction force of the spring, and the coil should be replaced or the circuit should be reconnected; 2.Check whether the moving mechanism and moving contact of the moving part of the AC contactor are stuck. If it is jammed, the action mechanism can be trimmed, the arc extinguishing cover can be straightened, and the position of the contact and the arc extinguishing cover can be adjusted to eliminate the friction between the two.

3.Check the hinge for rust or skew. If there is rust or skew, the shaft should be disassembled for cleaning to make the shaft rotate flexibly.

If the contactor or pick-up is disconnected after suction, it may be that the auxiliary contact in the contactor self-locking circuit is not connected or the contact is poor, so that the circuit self-locking link is ineffective. At this time, the actuating auxiliary contact can be refurbished to make it in good contact. First, there is a foreign body inside the contactor, second, the contactor voltage is wrong, for example, your voltage is 220V, but the working voltage of the contactor is 380V, third, the contactor coil burns out, the principle of contactor engagement, the balance and rolling is that the electrified coil produces magnetic force, and when the rock coil is burned, it cannot produce suction, so the armature cannot be sucked, and the fourth may be a line problem, and the line is broken.

There are many reasons why the contactor does not engage.

1. The coil of the contactor is burned, and the contactor is charged by the coil to generate electromagnetism, and the moving contact of the contactor is sucked together.

2. The control circuit is disconnected, resulting in the coil of the contactor being unable to be energized 3, and the thermal overload relay protection action is not reset or the button and other components are damaged.

No electricity, stuck, coil burned.
