Jog switch to AC contactor! How to connect AC contactor 01 and 02

Self-locking principle: the auxiliary normally open contact of the contactor is connected in parallel on the two terminals of the jog switch, when the jog switch is pressed, the coil of the contactor is energized and engaged, and the auxiliary normally open contact that is connected in parallel on the jog switch is also closed and connected, even if the jog switch button is returned and disconnected, the coil of the contactor is still energized and engaged.

A contactor auxiliary normally open contact is connected in parallel at the jog switch, that is, the self-locking link. When the jog button is pressed, the circuit is turned on, the contactor coil is energized, the contactor is engaged, and the auxiliary contact is normally open and normally closed, and the jog switch is released at this time, and the circuit continues to supply power to the contactor coil through the auxiliary contact connected in parallel at the switch.

Take the 220V contactor as an example, it is the live wire of the power supply, first connect a normally open button, then string a normally closed button, and then connect the coil of the contactor, and the other end of the contactor coil is connected to the neutral line of the power supply. Then connect a normally open auxiliary contact of the contactor in parallel at both ends of the normally open button, and the so-called self-locking line is realized.

I'm an electronics engineer and I wondered about your question when I was in junior high school. In fact, as you said, if the direct access circuit is not able to maintain the normal operation of the circuit, it must be processed by the self-locking circuit.

The coil is strung on the normally closed contact of another contactor, and when the motor 1 is working, the normally closed becomes normally open, so that the coil of the motor 2 is de-energized.

When the motor 2 is working, cut off the contactor coil of the motor 1.

Summary. The use of AC contactor is as follows: AC contactor 01, 02 is the control coil, connected to the control power supply, AC contactor L1, L2, L3 is the power supply side of the contactor, connected to the three-phase power supply.

2t t t3 is load side load. no is the normally open contact, and the contact is closed after the power is turned on, and the normally closed contact becomes normally closed. NC is a normally closed contact, which becomes normally open when energized.

The three-phase power supply is connected to the three main contacts of the AC contactor, and the other three main contacts are connected to the motor, and the AC contactor coil is connected to the control circuit, and the suction of the AC contactor can be controlled by the button.

How to connect AC contactor 01 and 02

The use of AC contactor is as follows: AC contactor 01, 02 is the control hall draft alarm coil, connected to the control power supply, AC contactor L1, L2, L3 is the power side of the contactor, connected to the three-phase power supply. Dress up 2t t t t3 is the load side connection respectful as the load.

no is the normally open contact, and the contact is closed after the power is turned on, and the normally closed contact becomes normally closed. NC is a normally closed contact, which becomes normally open when energized. The three-phase power supply is connected to the three main contacts of the AC contactor, and the other three main contacts are connected to the motor, and the AC contactor coil is connected to the control circuit, and the suction of the AC contactor can be controlled by the button.

How to connect the AC contactor if you can't suck it.

If you can't suck the AC contactor, first see if there is a problem with the contactor itself, and then check why there is no current in the line of the control coil.

How to connect these four wires.

You need a professional electrician to measure the voltage on site, and you can't judge the problem by just a few **.

A1 and A2 are connected to the power supply terminal, and K1 and K2 are connected to the control terminal of the AC contactor.

Look at the wiring on the diagram is correct, mainly to see whether there is a problem with the suction of the AC contactor itself, and then whether there is a voltage at the output end of this module.

You string the time relay contacts in the power supply circuit of the AC contactor's wire pack.

The working current of the AC contactor wire pack with high current is sometimes designed to be around 700 mA, and the inrush current at start-up is greater because the wire pack is an inductive load. If the contact capacity of the time relay you choose is not enough, then you can only add one more intermediate relay.

The principle of time-controlled switch control AC contactor - simply put, it is to use the contact of time-controlled switch to control the AC contactor coil.

220V power supply, 220V load, 220V power supply control - wiring diagram three-phase four-wire 380V power supply, 380V load, 220V wiring control - three-phase four-wire system, 380V power supply, 380V load, 380V wiring control -

The wiring diagram of the AC contactor connected to the time-controlled switch is as follows:

Generally, the three-phase contactor has a total of 8 points, three inputs, three outputs, and two control points. The output and input are corresponding, and it is easy to see. If you want to add self-locking, you also need to connect the wire from one of the terminals at the output point to the control point.

How to connect the 380V AC contactor to the time-controlled switch.

How to connect the time-controlled switch to the AC contactor? Few electricians teach you, but the connection is very simple.

Time-controlled switch controls the wiring diagram of 220V AC contactor.

Time-controlled switch control 380V AC contactor wiring diagram.

To give you a more detailed circuit diagram, don't understand and ask again! I'm sure you will see it!

2 If you use the compass button to control an AC contactor, and then control a power-off delay relay by the Wu Xian normally open contact of the AC contactor, and then control an indicator light from the normally open contact of the power-off delay relay, then when the button is pressed, when the indicator light will light up the cavity finger beat, and when will it go off? and draw a circuit diagram.

Hello, dear, I am glad to answer for you to use the button to control an AC contactor, and then control a power-off delay relay by the normally open contact of the AC contactor, and then control a vertical indicator light by the normally open contact of the power-off delay relay, then when the button is pressed, the indicator light will be lit at 2 seconds The control requirement is Y0 Y78 The lamp is lit in turn from left to right at a speed of 2s, and then the light is turned off from left to right according to the chain after the light is fully on

The three-phase main circuit is wired as follows: the outlet end of the circuit breaker is connected to the inlet end of the AC contactor, and the outlet end of the AC contactor is connected to the load.

The control circuit is wired as follows: the outlet end of the control power fuse is connected to one end of the stop button (normally closed contact), the other end of the stop button is connected to one end of the starting button (normally open contact), and the auxiliary contact of the AC contactor (normally open contact) is connected, the other end of the starting button is connected to the other end of the auxiliary contact of the AC contactor, and then one end of the AC contactor coil is connected, and the other end of the AC contactor coil is connected to the other phase control power supply.
