Course Description

Course Code : INDR0040

A highly practical course which will aid diagnostic approach and lead to faster identification and resolution of faults.

This is a predominately hands on course designed for maintenance engineers and multi skilled technicians who are likely to be the first to respond to breakdown situations. It will underpin a basic understanding of control systems, looking at the commonalities between disciplines, their concept and construction.


Course Objectives

To understand the relationship between pneumatic, electro-pneumatic, PLC's and electrical systems.

To be able to approach a breakdown situation in a methodical manner.

To be able to construct electrical and pneumatic circuits following schematic drawings.

Understand the basic principles of Programmable Logic Controllers (PLC's)
