Amatrol's portable electric relay control troubleshooting training system features interactive eLearning curriculum that integrates various types of learning methods to create an engaging, effective learning experience. Amatrol’s multimedia eLearning curriculum includes text with voiceovers, videos, 3D animations, pictures, and interactive activities, quizzes, and self-reviews. Specific electrical relay control topics covered include: logic elements; ladder diagrams; electro-pneumatic solenoid valves; relay operation and applications; limit switch operation and applications; time-delay relays; multiple cylinder control; and machine modes of operation. Within these topics, learners will study objectives like connecting and operating a logic circuit given a ladder diagram; designing a ladder diagram using one or more logic elements; connecting and operating a relay to perform a seal-in function; designing a logic circuit that uses a limit switch to sequence an event; connecting and operating a two-pushbutton jog circuit that will jog two cylinders independently; and designing a continuous-cycle, synchronized cylinder circuit with a manual mode.
