Troubleshooting low voltage controls

Abstract

Control components are a vital aspect of any industrial process. It is argued that costly shutdowns can be minimized or eliminated through a complete understanding of the control devices along with a conscientious maintenance program and troubleshooting procedure. The electromechanical design of various types of starters, contactors, and overload relays are analyzed in terms of operation, application maintenance and troubleshooting. Specific suggestions for troubleshooting procedures are offered for various problem scenarios.<>
