| Abstract: | It requires the reliability and safety of some important mechanical limit switches in hoisting equipments very much. With the application of the PLC (programmable logical controller) programming and coder, the switches can be effectively monitored. As long as the position changes or the switch fails, the monitoring can simultaneously be warning to stop the working of the machine in order to ensure the safety of the equipment. |
