1. Overview.
The safety emergency stop button is an important safety device used to quickly stop the operation of the machine in an emergency. In order to ensure the safety of personnel and the stability of equipment, the installation of the emergency stop button must comply with certain standards and specifications. This standard specifies the installation requirements and operating guidelines for the safety emergency stop button.
2. The emergency stop button should be standardized to meet the requirements of appearance and feel.
1.The E-STOP button should be in a striking color and shape so that the operator can quickly identify it.
2.The button should have a clear "emergency stop" logo, which should be clear and easy to read, not easy to blur.
3.The buttons should be of the right size and shape so that the operator can press them easily and accurately.
3. The installation height of the emergency stop button should meet the specifications, usually 13 to 15 meters.
1.The installation height should take into account the height and operating habits of the user, so that it can be easily reached and pressed in case of emergency.
2.The installation location should take into account the machine operating area and safe access so that the button can be quickly pressed around the machine and on the aisle.
Fourth, the emergency stop button should have a conspicuous sign to facilitate personnel operation.
1.The button should be affixed with a conspicuous "Emergency Stop" logo, and the logo should be in a contrasting color for quick identification in an emergency.
2.The logo should not be easy to fall off or wear out to ensure that it remains clearly visible after prolonged use.
5. At least one emergency stop button should be set up in each fire prevention zone.
1.The fire zone refers to the fire hazard area divided according to the fire code, and independent emergency stop equipment should be set up in this area.
2.The E-STOP button should be installed near the main entrance and exit of the fireproof partition so that it can be quickly reached and pressed in an emergency.
6. The walking distance from any location within a fire zone to the nearest emergency stop button should not be greater than 30 meters.
1.Within the fire zone, the distance from any location to the nearest E-STOP button should not exceed the prescribed walking distance to ensure that the button can be reached quickly and pressed in an emergency.
2.When arranging machines and equipment, consider leaving enough space and access for operators to quickly reach the E-STOP button position.
7. The wiring margin in the emergency stop button should not be less than 10 cm.
1.When installing the E-STOP button, it should be ensured that the wiring margin is sufficient so that the wiring operation can be easily carried out during later maintenance and inspection.
2.The margin length should not be less than the specified minimum to ensure sufficient flexibility to meet actual needs.
8. The emergency stop button needs to be linked with the machine safety control system.
1.The emergency stop button should be linked to the machine's safety control system so that the machine's emergency stop program can be triggered immediately when the button is pressed.
2.The linkage equipment should have reliable electrical performance and stability to ensure that it can accurately respond and execute stop commands in an emergency.
3.When installing the E-STOP button, it should be ensured that it is properly connected to the machine control system and that the necessary tests and verifications are carried out to ensure that it functions properly and complies with the relevant safety standards.
