The construction of the cell can be performed entirely by the trainees. Using industry-standard work orders, standard operating procedures, schematic diagrams and manufacturers technical manuals as resources, students assemble the frame and install the electrical wiring for the Maintenance Cell and add-on components. Once constructed, instructors can remotely insert faults in the electromechanical systems. Trainees can thus develop troubleshooting skills in a relevant, engaging manner. Each task includes validated industry standards providing measurable criteria for assessing students’ performance.
The JobMaster® 1600 Electromechanical Maintenance Cell is the ultimate capstone to any industrial maintenance / mechatronics program. The Electromechanical Maintenance Cell ensures relevant instruction by enabling a robust simulation of the workplace and a more valid delivery of career skills. Students learn to assemble, wire, maintain, and troubleshoot electromechanical systems just as if they were in the industrial environment. This results in the most effective authentic assessment of a trainees ability to succeed in the field of mechatronics or industrial maintenance.
Standard Features
