Certificate in Industrial Power and Control Technology
COURSE DESCRIPTION:
This course is devoted to the study of sequential control. First, the course covers electromagnetic control
devices and circuits for starting, accelerating, stopping, and reversing ac and dc motors. This is followed by the
study of programmable logic controllers. Basic control circuits will be programmed on the Allen-Bradley
Micrologix 1000 line of PLCs. Advanced control circuits will be programmed on the Allen-Bradley SLC-500
line of PLCs.
COURSE OBJECTIVES:
I. To provide the student with a basic understanding of electric motor control circuits.
II. To familiarize the student with the practical aspects of electromagnetic motor controls for both ac and dc
motors.
III. To teach the student how to do basic programming on the Allen-Bradley line of PLCs.
IV. Upon completion of EEL 202, students will be able to:
a. State the important safety rules related to working around electrical devices and specifically those
that relate to working with electromagnetic motor controls and PLCs.
b. State the purpose and general principles of electric motor control.
c. List the conditions of starting and stopping, speed control, and protection of electric motors.
d. Identify common magnetic motor starters and overload relays.
e. Draw the wiring diagram symbols and explain the operation of various pilot devices including push
buttons, pressure switches, float switches, flow switches, limit switches, and temperature switches.
f. Describe the operation of two-wire and three-wire circuits.
g. Interpret schematic (elementary) and wiring diagrams.
h. Connect control circuits using schematic and wiring diagrams.
i. Develop a schematic and a wiring diagram to obtain a specific control function, connect the circuit,
test and troubleshoot the circuit.
j. Develop and connect circuits to accomplish motor sequence control, reversing, jogging and
plugging.
k. Develop and connect circuits to accomplish reduced voltage starting of ac induction motors.
l. Describe the use of series resistance for limiting the armature current when starting a dc motor.
m. List the principle parts of a programmable controller.
n. Convert a relay schematic to a schematic used for programming a programmable logic controller.
o. Program basic control circuits on an Allen-Bradley Micrologix 1000 PLC.
p. Program advanced control circuits on an Allen-Bradley SLC-500 PLC.
q. Describe the processor memory and methods of addressing.
r. State the three primary reasons for grounding, and give example applications of each.
