How to wire the emergency stop switch?
Just connect the normally closed point of the emergency stop switch to the control circuit (contactor coil) of the contactor in series! Pressing a few buttons will open the closed point of the emergency stop, which also disconnects the circuit of the contactor coil and contacts Stop the work and cut off the main circuit! Use a multimeter to measure the emergency stop switch. If it is open when you don’t press it, it will be closed! Your contactor has L1 ---- L6 is the main circuit if it is marked with K1, K2, the two contacts at the bottom are the coils of the contactor, and you can see that they are wired into the internal, but you can't connect it, it's better to find someone to fix it!
How to use an emergency stop switch?
Precautions for the use of emergency stop button switches: In industrial safety, it is required that all machines whose transmission parts directly or indirectly cause harm to the human body under abnormal conditions must be protected. The emergency stop button is one of them. Therefore, the emergency stop button must be added when designing some machines with transmission parts. And it should be set on the surface of the machine that can be easily pressed by personnel, and there should be no obstructions. The emergency stop button switch can be directly pressed down to quickly stop the whole equipment or release some transmission parts. If you want to start the device again, you must release this button, that is, you only need to rotate it clockwise about 45° and then release it, and the pressed part will pop up. That is to "release".
The role of the emergency stop switch
The function of the emergency stop switch is to make the machine stop immediately under any circumstance, and stop the machine immediately when an emergency occurs during its function to prevent damage or expansion of losses.
Emergency stop switch principle
The emergency stop switch is usually a manually controlled push switch (the button is red), press to lock and rotate to release the red mushroom head button switch or round button switch (some emergency stop switches are equipped with LED lights for easy operation), in series Access to the control circuit of the device, used to directly disconnect the power of the control circuit in an emergency, so as to quickly stop the device to avoid abnormal operation. It is a kind of master control electrical appliance. When the machine is in a dangerous state, the power supply is cut off through the emergency stop switch to stop the operation of the equipment, so as to protect the safety of people and equipment.
