Industrial Troubleshooting and Repairs
“Mastering The Act of Industrial Troubleshooting”
Workshop:
Project to test participants’ knowledge and understanding of the training will be provided.
"In our Industrial Troubleshooting and Repairs skills, participants are allows to work with their hands on faulty equipment, they are given challenges to troubleshoot, discovery fault(s) within the emergency time response limit"

Module 1
Lesson 1: Terminologies and Troubleshooting Sequence
Understanding the terminologies, tools and techniques, standard “Blue-Print” for problem analysis, manufacturer data sheet, manufacturer faults detection and troubleshooting guide, review of vendors and organizations own troubleshooting documentation, organization’s safety rules and troubleshooting procedures. The troubleshooting approach: Identifying the problem, Defining Problem Area, Identifying Possible Causes, Repairing or replacing the component, testing the system. Troubleshooting sequence: Preliminary checks, analyzing the complaint, Sequence of Operation, tracing circuit problems, troubleshooting before Installation, troubleshooting after installation, equipment changes,repairs and modifications.
