Amatrol's portable electric relay control troubleshooting eLearning course covers important topics, such as:

Control Logic

Learners begin with an introduction to control logic, including logic elements (NAD/OR/NOT/NOR/NAND), ladder diagrams, and electro-pneumatic solenoid valves. Individual lessons focus on topics like the six elements of control logic, five rules of drawing a ladder diagram, the function of a solenoid-operated fluid power valve, and the function of a power diagram. Learners will also practice skills, such as connecting/operating an AND/OR/NOT/NOR/NAND logic, reading/interpreting the operation of a circuit given a ladder diagram, and designing a control circuit in a ladder diagram format to operate a solenoid valve.

Sequencing Control

In this module, learner will encounter components of sequencing control, including relay operation, relay applications, limit switch operation, and limit switch applications. Individual lessons focus on topics like the function/operation of an electromechanical relay, the operation of a relay performing control logic, the function of a limit switch, and the operation of a safety interlock circuit. Learners will also practice skills, such as reading/interpreting a basic ladder diagram, designing a logic circuit that uses a relay, designing a logic circuit that uses a limit switch to sequence an event, and designing a continuous-cycle cylinder reciprocation circuit with a safety interlock.

Timers and Advanced Systems

Learners using Amatrol’s Electric Relay Control eLearning course will study the principles of timers and advanced systems, including time-delay relays and applications, multiple cylinder control, and machines modes of operation. Individual lessons focus on topics like the operation of an on-delay/off-delay timer relay, the operation of a timer relay, how multiple cylinders are controlled using one limit switch, and two applications of manual controls. Learners will also practice skills, such as connecting/operating a control circuit with a timer relay, designing a control circuit to perform time-driven sequencing, connecting/operating a dual-cylinder control circuit using two limit switches, and designing a continuous-cycle, synchronized cylinder circuit with a manual mode.

Troubleshooting

Amatrol's portable electric relay control troubleshooting eLearning course uses FaultPro, an electronic fault insertion system that is only available from Amatrol, to insert faults into the system for troubleshooting. During the learning process, FaultPro allows learners to insert faults in the system as they progress through the step-by-step procedures learning industrial troubleshooting methods. Then, FaultPro can be set to randomly select and insert a fault to test a learner’s troubleshooting abilities and prepare them to solve real-world technical problems once they’re in the field. This system allows learners to use a digital multimeter to perform troubleshooting skills like: testing input and output devices, relays, and relay logic circuits.

NOTE: Learning system also available without troubleshooting (990-EC1/M11132).
