The two indicators of the motor are lit up, what is the reason why it can t start?

Schematic: <>

Button interlock, contactor interlock.

Below is the physical picture:

1. After the circuit is connected, the energized motor does not attract the contactor, the main circuit is not electric or the motor is broken, and the contactor is not engaged and the control circuit is faulty.

2. Press the start button and the motor rotates normally, and then press the stop button without stopping: the control circuit is wired incorrectly or the stop button is normally closed and cannot be broken by short circuit.

3. Connect the composite dynamic break switch to the moving switch: the normally closed contact (dynamic breaking switch) and normally open contact (dynamic switch) in the button switch are connected incorrectly. Please don't do it yet, and then pick it up after reading the picture.

1. Check whether the coil of the contactor, whether the auxiliary normally closed is on, whether the normally closed contact of the thermal relay is on, and whether the button is easy to use, etc., the most important thing is that the wiring is correct.

2. The contactor is self-locking at the inlet end of the button.

3. The motor will start.

Note: Switch the normally closed contact of the actuating and closing button, and switch the normally open contact of the inverted and closing button.

First question! The motor won't rotate is not that you didn't press the start button! The control line is not energized!

Second question! The stop button should be connected to the closing contact! If you are connected to a moving disconnecting contact!

Pressing the start button won't start the motor! Third question! The stop button is turned off!

Start button to pick up the house! If your third problem is with the stop button, the motor won't start! Of course, the motor does not turn!

If the problem appears on the start button! As soon as the circuit is energized, the motor will spin! Pressing the button doesn't stop either!

Your problem conditions are not clear, is it completely unresponsive or difficult to start, you must have a problem with the line, including the control line of the control elements of the line, it is possible, but I think there should be no problem with the motor, you take a look.

1》The motor is damaged or the load is too large and stuck.

2》The main contact of the contactor is damaged or individually damaged.

3》Power supply phase off (non-contactor coil two-phase).

The two indicators of the motor are lit up, what is the reason why it can't start? Hello dear, the three-phase asynchronous motor can not be started in reverse, fundamentally speaking, the failure to start must be the reason why the resistance torque is greater than the electromagnetic force guess sock moment, the specific reasons for the resistance torque is greater than the electromagnetic torque are many, but it is nothing more than three aspects of the problem, that is, the power supply square spike answer surface, the motor itself, the problem of good wear. Hope mine is helpful to you, thank you and have a great day!

What is the situation when the indicator light is on, but the motor is not working?

This situation occurs when the power supply of the motor secondary control line is connected from the motor power switch. When the motor power switch is turned off or tripped, the power supply of the secondary control line is still in a normal state, and at this time, the contactor of the motor controlled by the simple hole can be engaged normally, and the operation indicator light is also on normally. If it belongs to the above line, please check whether the power switch of the primary line of the electric barrier is tripped or turned off.

The reason why the car dashboard lights are fully lit.

The CAN bus of the Oak State is faulty, and the CAN interface of the ECU is not in good contact.

2.Excessive dirt and carbon deposits, abnormal air circulation, and inability to accurately control the normal air intake volume, resulting in unstable gas levels and making the engine not work well.

3.The low fuel pressure combined with the poor constant pressure performance leads to a low level of atomization in the system, making it difficult for the car to start.

Extended Materials. About the car dashboard.

1.The car dashboard is a device that reflects the working conditions of each system of the vehicle. Different cars have different gauges. However, the conventional instruments of general automobiles include speedometer, tachometer, oil pressure gauge, water temperature gauge, fuel gauge, charging gauge, etc. Beam liquid.

2.Hyundai has a variety of indicators or warning lights under the instrument panel, such as coolant level warning light, fuel level indicator, washer liquid level indicator, charging indicator, high and low beam pitch beam light indicator, transmission gear indicator, brake anti-lock braking system (ABS) indicator, drive force control indicator, airbag (SRS) warning light, etc.

Based on the information you provided, I'm guessing that you might be using a motor control device that flashes the forward light when the motor reverses and stops. This situation is generally caused by interference caused by the reverse electromotive force when the motor is running in the opposite direction.

The old ways to solve the problem of stupidity can be tried here:

1.Check whether the wiring of the motor control device is correct and make sure that the motor is connected correctly;

2.Try to increase the resistance of the motor winding to reduce the effect of reverse electromotive force;

3.Electromagnetic interference suppression components such as capacitors and resistors can be added to the motor control device to reduce the interference effect of reverse electromotive force.

4.If the above methods do not work, you can also try to change the motor control scheme or replace the motor.

If you are unsure of how to operate or if there is a safety hazard, it is important to seek professional technical support or consult the relevant manufacturer of the gear upgrade.

The KM1 coil rotates forward when energized, and the KM2 coil rotates backwards when energized.

All you need to do is connect two indicators in parallel on the KM1 coil and KM2 coil.

But it should be noted that the power supply voltage of the coil is 380V, I don't know if you have an indicator with a voltage of 380V. As shown in the figure below.

The coils in km1 and km2 are connected in parallel to the indicators.

There are three kinds of bend belt original nonsense cherry cause:

1. It may be that the voltage tester is not in good contact or the terminal is rusty.

2. Either the motor is out of phase and is easy to be damaged.

3. Also the trouser tufts may lead the line from other positions.

Check if the time relay is normal. Generally, the time relay does not work and cannot be converted to the operating state.
