What is the role of the master controller?

     The master controller is primarily designed for managing multiple control loops in a specific sequence, allowing for precise and automated operation. It is commonly used to control the movement of a motor's shoulder by activating contactors. Unlike a cam controller, which relies on mechanical cam profiles for switching, the master controller follows a pre-programmed sequence to turn circuits on and off. This makes it ideal for applications where consistent and repeatable control is required. The device ensures smooth transitions between different operational stages, reducing wear and tear on electrical components. Additionally, its structured approach allows for easier troubleshooting and maintenance. By using a master controller, operators can achieve greater efficiency and reliability in complex automation systems.
