Abstract

This paper describes the research results in a PLC application system with a ladder diagram design and its implementation using a Schneider PLC to prevent electrical loads in a building from starting simultaneously. This paper discusses the problems that exist in the industry and proposes a solution technique using PLC. The problem is that more and more electrical loads containing electric motors use ON and OFF automation to control the motors to save electrical energy consumption. But the electric motor is an inductive load that consumes much electrical energy in the starting process. If the starting process coincides with other electrical loads, it will cause the energy supply through the electrical panel becomes unstable. To deal with this real problem in the industry, a PLC-based electronic device management system was developed in the research. The ladder diagram of the made PLC system is presented in this paper. From system testing and data taken during research in the laboratory, the system created in this study has successfully prevented the electrical loads from starting simultaneously. This can be proven from the application of the system where the three electrical loads that use the Air Conditioner (AC), which contains a motor, are not started simultaneously.
