Assisting in the installation of process control equipment
Overview
This standard identifies the competences you need to assist in the installation of process control equipment, in accordance with approved procedures. You will be required to assist in the installation of a range of process control equipment, which typically includes process controllers or sequential controllers (such as programmable logic controllers (PLCs), or equipment controlled by personal computers (PCs)), and which are working in an integrated system involving two or more of the following interactive technologies: mechanical, electrical or fluid power. You will also install peripheral components and communication links, and assist with the loading/downloading of process controller programs, check them for errors, and create back-up copies of completed programs.
This standard does not involve maintenance/repair type activities, such as removal and replacement of existing equipment.
You will be required to use the appropriate tools and equipment throughout the installation, and to apply a range of installation methods and techniques to position, level and align the equipment, and to make connections to sensors and actuators, which could be electrical, fluid power, water or fuel supply, as appropriate to the equipment installed. The installation activities will include making checks and adjustments, in line with your permitted authority, and assisting others to ensure that the installed equipment functions to the required specification.
Your responsibilities will require you to comply with organisational policy and procedures for the installation activities undertaken, and to report any problems with the activities, tools or equipment used that you cannot personally resolve, or are outside your permitted authority, to the relevant people. You must check that all tools, equipment and materials used in the installation activities are removed from the work area on completion of the work, and that the relevant job/task documentation is completed accurately and legibly. You will be expected to work to instructions, alone or in conjunction with others, taking personal responsibility for your own actions, and for the quality and accuracy of the work that you carry out.
The installation activity may be carried out as a team effort, but you must demonstrate a significant personal contribution to the installation activities, in order to satisfy the requirements of the standard, and you must demonstrate competence in all the areas required by the standard.
Your underpinning knowledge will be sufficient to provide a sound basis for your work, and will enable you to adopt an informed approach to applying installation procedures for process controllers. You will have an understanding of the equipment being installed, and its installation requirements, in adequate depth to provide a sound basis for carrying out the installation process safely and effectively.
You will understand the safety precautions required when carrying out the installation activities, especially those for ensuring the safe isolation of services. You will be required to demonstrate safe working practices throughout, and will understand your responsibility for taking the necessary safeguards to protect yourself and others in the workplace.

- the devices and systems for storing programs
- the different types of interface cards
- the numbering system and codes used for identification of inputs and outputs
- how to interpret a program within the process controller for specific elements
- how to make adjustments to components to ensure that they function correctly
- why electrical bonding is critical, and why it must be both mechanically and electrically secure
- how to conduct any necessary checks to ensure the equipment integrity, functionality, accuracy and quality of the installation (including the fitting of guards to all moving parts and covers on electrical connections)
- how to recognise installation defects (such as dry connections, communication difficulties, ineffective fasteners, foreign object damage or contamination)
- the importance of ensuring that the completed installation is free from dirt, swarf and foreign object damage, and of ensuring that any exposed components are correctly covered/protected
- the problems that can occur with the installation operations, and how these can be overcome
- the fault-finding techniques to be used if the equipment fails to operate correctly
