How to measure the paths and know the validity of the ingredients.

Service measuring (amplifier)

Using the millimeter, the bell position is set, if it gives the whistle it is healthy.

In the event of the safety of the amplifier, it gives equal reading during the opposite of the poles, and if it is damaged, it gives a different reading during the opposite of the poles.

Service measuring (headphone)

Using the millimeter, the bell position is set, if it is given a whistle, it is healthy.

In the event of the safety of the headphone, it gives equal reading during the opposite of the poles, and if it is damaged, it gives a large percentage reading during the opposite of the poles.

Knowing the validity (keyboard)

All the buttons on the keyboard are two tracks and to measure any path, we use the reluctance measurement.

1) On the mode of "diode", the red end of the millimeter is placed on the floor of the Board and the Black Perfume of the Mloreter on both ends of the button to the button

Three-Phase Motor Control Circuit – Start/Stop System Explained

This diagram shows a three-phase motor control system using a start/stop push button station with safety and protection components. It’s a basic yet essential setup for controlling industrial motors. Let’s break it down!

⚡ Main Components:

MCB (Miniature Circuit Breakers) – Protect the circuit from overload and short circuits.

Contactor (K1) – Electrically controls the motor power supply.

Overload Relay (bottom of the contactor) – Cuts off the motor if it draws too much current.

Start Button (MARCHA – Green) – Energizes the contactor to start the motor.

Stop Button (PARADA – Red) – De-energizes the contactor to stop the motor.

Indicator Lamps (H1, X1) – Show motor status (ON/OFF or fault).

Three-Phase Motor (MOTOR) – Converts electrical energy to mechanical motion.

⚙️ How It Works:

When you press the green button (MARCHA):

The contactor coil (A1-A2) is energized.

This closes the main power contacts and powers the motor.

The auxiliary contact (13-14) keeps the circuit latched even after you release the button.

Pressing the red button (PARADA):

Breaks the control circuit and de-energizes the contactor.

The motor stops immediately.

The overload relay protects the motor from damage due to high current.

Indicator lamps light up to show whether the motor is running or stopped.

🧠 Why This Matters:

This type of control circuit is widely used in:

Industrial machinery

Pump systems

Conveyor belts

HVAC systems

It ensures safe, reliable, and efficient control of motors!
