The operation and control of these circuitsusing three pole switches, electromagnetic switches, and pushbuttons. The operation and control using the PLC device by ContactL(Easy, logo, S7 etc)Hours P 8It also presents the methods of fault finding and repair. (h/w)TGeneral objective of the course:The course aims to teach the trainees about the circuits needed to operate and control threephaseinduction motors. These circuits include operation, starting, speed control, and reversing thedirection of rotation. This course enables the trainees to investigate faults in these circuits and clearthese faults.The course also aims to teach the trainees how to use the PLC to operate and control threephaseinduction motors.Behavioral Objectives:The trainees should be able to:1. Describe the components and construction of three-phase induction motors.2. Read and connect the operation circuits of three-phase induction motors.3. Read and connect the control circuits of three-phase induction motors.4. Investigate the faults and clear these faults.5. Read and connect the operation and control circuits of three-phase inductionmotors.6. Representing operation and control circuits using logic expressions and logiccircuits.7. Use the PLC to operate and control three-phase induction motors.- 80 -
