1. Introduction 简介
1.1 Purpose目标:
1.1.1 This manual is intended to aid the machine operators and should be kept in the control room or near the primary operator interface.
1.1.1 本手册旨在帮助机器操作人员
1.1.2 The information in this manual describes normal activities for setting up and operating the system. It includes safety information that MUST be followed when performing those tasks. Failure to follow the safety information can result in serious injury.
1.1.3 This manual MUST be read and thoroughly understood by all personnel who will be operating the system. If an operator is unable to read this manual, it MUST be thoroughly communicated to that individual before they attempt to operate the system.
1.2 Personnel:
1.2.1 The personnel operating this equipment MUST have basic minimum skills. It is not necessary that all
employees have each skill, but operators must be knowledgeable in each of the areas listed below. With a good knowledge base, maximum system productivity can be achieved.
1.2.2 NOTE: In order to realize maximum system productivity, Glasstech recommends that supervisors be familiar with all areas listed below and / or have previous experience in the glass industry. 1.2.3 The operators should understand and be able to: ? Make minor mechanical setup adjustments ? Understand glass tempering theory ? Inspect glass for defects
? Develop and setup heat profiles for various thicknesses of glass ? Work with computers ? Read process flow charts
? Have a working knowledge of mechanical systems and how different systems work together.
NOTE: Glasstech will provide training on these topics during installation, but previous experience is very beneficial.
