Course Description

Course Code : IN005

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.
