The emergency stop button can also be called the “emergency stop button“, as the name implies: when an emergency occurs, people can quickly press this button to achieve protection measures. At present, the machinery and equipment do not intelligently detect the surrounding environment and its own operating status at any time, and still need on-site operators to photograph the emergency stop button at the emergency time to avoid major personal and property losses, but the emergency stop button will have the following misunderstandings during use: 01 Wrong use of the normally open point of the emergency stop button: some sites will use the normally open point of the emergency stop button and then through PLC or relay to achieve the purpose of emergency stop, This wiring method cannot be cut off immediately when the contact of the emergency stop button is damaged or the control loop is broken. The correct approach should be to connect the normally closed point of the emergency stop button to the control loop or main loop, and quickly stop the output from the actuator at the moment the emergency stop button is taken.02 Wrong use occasions: the emergency stop button is only used when the operation is accidental, and some maintenance personnel press the emergency stop button after the maintenance work, in this case, once the emergency stop button is damaged or other personnel unknowingly reset the emergency stop button, it may cause major losses to people and property. The correct approach should be to list the power outage and detect the lack of power and carry out maintenance work.03 Wrong usage habits: Some sites, especially the scene with low frequency of use of the emergency stop button, may ignore the regular inspection of the emergency stop button, once the emergency stop button is blocked by dust or failure and is not found in time, it may not be able to cut off the danger in time when the fault occurs, resulting in major losses. The correct practice is to check the E-STOP button regularly to avoid surprises.
