33、p refers to the start-up of a newly built, sub-stantially changed manufacturing facility, or the start-up of a portion of a manufacturing facility which has had a process change requiring new equipment or controls.The responsibilities of the Control Systems Technician (CST) include installation, tro

34、ubleshooting, repair, and routine maintenance of instru-ments. A large portion of this work includes troubleshooting and coor-dinating repairs to control loops throughout the plant. The CST follows company and craft standards and specifications and coordinates his or her activities with Operations a

35、nd with other crafts and departments. A CST may be a direct or contract employee.As a CST this may be the first time you have been asked to participate in a start-up; or perhaps youre very experienced and have participated in many start-ups during your career. In any event, as part of the start-up t

36、eam, you should know what your roles and responsibilities are during this critical period. The chapters of this book cover the major aspects of a CSTs involvement in a plant start-up:Defining the role of the CST during start-up Applicable safety practices and standards Documenting the start-up proce

37、ss Working with others Verifying and managing changes Personnel requirements and responsibilities How a CST assists Operations and other site personnel Tuning control loops Job DescriptionsCST RolesCST TasksInitial Equipment Start-up Activities2 Start Up: A Technicians GuideSometimes start-ups must

38、be accomplished with limited personnel resources and under extreme time pressure. An effective start-up plan, which well discuss in Chapter 3, depends on knowing what technicians should do and how many will be requiredand availableto do it. Man-agement will take personnel limitations into account, b

39、ut CSTs must also understand the roles of the personnel involved in the start-up. Sometimes this information gets communicated verbally, sometimes in formal job descriptions. This chapter will discuss the importance of job descriptions, and the different roles you may be asked to play throughout the

40、 start-up.The role of the CST varies from plant to plant. For example, plant size may determine the roles a CST will play. Where the CST is part of a small group, or possibly working alone, the job will be different than that of a CST working with a larger department. In a larger organization, the C

41、ST may have less independence, with specific jobs he or she has to perform during start-up, and will not necessarily be involved in every function described in this book.The information in this book is intended to apply to many differ-ent types of industries that might employ a CST. Obviously, the t

42、ype of industry and its management will determine exactly how the CST will function within the organization and during start-up.Finally, the start-up is one of the last activities to occur in an overall project which again may be for a newly built, substantially changed or position of a manufacturin

43、g facility undergoing process or equipment changes. Therefore, much of the information in this book pertains to proj-ect execution and control, that is, the steps and deliverables necessary to complete the work to start-up the new and modified facility. Some of the work the CST is responsible for ac

44、tually occurs in preparation of the start-up (e.g., installation, programming, loop check). The Role of the CST in a Start-Up 3DEFINITIONSProject Execution and Control (Project Management): Planning, organizing, securing, and managing resources is about the successful completion of specific project

45、goals and objectives. Resources, may be people, materials and money. Project goals may include but not be limited to a set of agreed upon Deliverables.Deliverables:Plans - Construction, procedures, objectives Drawings - “as built”, loop sheets, documents, loop folders Calculations studies, material

46、and energy balances Purchased Equipment Installation Services - installation, programming, training, SAT, FAT Project: a temporary endeavor, with a defined beginning and end. This is in contrast to the normal operations of a plant, which the com-pleted start-up is expected to achieve.1.1 JOB DESCRIP

47、TIONSThe job description not only defines work responsibilities for the per-son doing the job, it also helps the employer explain what the position re-quires when hiring and during performance evaluations. As a CST, your job description will cover your essential job functions, including those requir

48、ed during a plant start-up. Management can use the job description when hiring to review the position with a potential employee, to orient new employees to their position, and to evaluate current employees job performance. Some job descriptions are very specific while others are more general to allo

49、w for flexibility in work assignment. Job descriptions include the following elements:Job summary statement Basic functions of the position Responsibilities of the position (identifying those tasks that are considered essential)Supervisory responsibilities (if applicable) Skills necessary for the position (e.g., an understanding of math as it pertains to electrical and instrument equipment. Additional skill, knowledge or experience includes but m
