Students will be able to:
1. interpret electrical motor control and programmable controller system
schematics, including identifying schematic symbols, signal flow, and operation of the
components and system;
2. adjust and test limit switches, pressure switches, float switches, and electronic
proximity sensors;
3. use a multimeter to measure voltage, current, and resistance in an electrical circuit to
verify system operation and power levels;
4. select, install, and test fuses and circuit breakers;
5. install and test electrical relay control components in a control system;
6. install and test electro-fluid power components and circuits;
7. troubleshoot a solenoid-operated fluid power relay control circuit;
8. test and replace transformers;
9. effectively use computer applications, information systems, and programming;
10. employ mechanical fabrication procedures;
11. demonstrate ethical behavior and industry professional standards;
