Unit Descriptor

Unit descriptor 

This unit covers the operation of a local control panel. These controllers use simple control algorithms and only a limited number of control loops. Typically it will be located on the plant, but may also be located off plant and include simple panels in a control room which are not part of the main control panel.

Application of the Unit

Application of the unit 

In a typical scenario, the operator will use the local control panel to monitor and control process variables such as temperature or pressure and the operation of valves and pumps to add raw materials, additives, and discharge product. Routine start up and shut down of the equipment using the local control system is expected, as is emergency response and shut down. This includes but is not restricted to PLC control.

This includes an understanding of the process and all OHS requirements including emergency situations.

The unit does not apply to operating a control panel for an integrated plant, where the control is from a separate control room or control system, which is covered by PMAOPS305B Operate process control systems. The plant technician would:

  • be aware of and contribute to a safe working environment
  • identify and report operational problems to their supervisor / control room operator
  • execute all routine activities, including process monitoring, start up, shut down and adjustments, in accordance with position description.

Generally the operator would operate independently in the plant. The operator would be expected to be capable of performing all parts of this unit. At all times they would be liaising and cooperating with other members of the team.

Required Skills and Knowledge

REQUIRED SKILLS AND KNOWLEDGE 

This describes the essential skills and knowledge and their level, required for this unit.

Required skills 

Competence includes the ability to distinguish between causes of problems/alarms/fault indications such as:

  • instrument failure/malfunction
  • electrical failure/malfunction
  • mechanical failure/malfunction
  • equipment design deficiencies
  • product parameters (temperature, flows, pressure and levels).
  • An ability to communicate with other work groups and personnel during the operation and monitoring of this equipment is considered an essential element of this unit of competency.

Required knowledge 

Competence includes an understanding of underpinning knowledge. Demonstration of competence in this unit must include knowledge of:

  • all items on a schematic of the controller and the function of each
  • principles of operation and location of the process/production equipment
  • specific plant process operations
  • product specifications and tolerances
  • systems operating parameters
  • basis of control for the process
  • emergency shutdown procedures
  • process specific physics, chemistry and mathematics
  • process drawings, eg P&ID, PFD, cause and effect
  • instrumentation and control systems, eg relevant primary sensing devices, final control elements, transducers/transmitters
  • simple control loops, including PID control, set points, controlled variable, indicated variable
  • effective communication techniques.

Evidence Guide

EVIDENCE GUIDE 

The Evidence Guide provides advice on assessment and must be read in conjunction with the Performance Criteria, Required Skills and Knowledge, the Range Statement and the Assessment Guidelines for the Training Package.

Overview of assessment 

Assessment for this unit of competency will be on a local control system. Assessment of this unit should demonstrate competence on actual plant and equipment in a work environment. The unit will be assessed in as holistic a manner as is practical and may be integrated with the assessment of other relevant units of competency. Assessment will occur over a range of situations, which will include disruptions to normal, smooth operation.

Simulation may be required to allow for assessment of parts of this unit. Simulation should be based on the actual process control system and will include walk-throughs of the relevant competency components. Simulations may also include the use of case studies/scenarios, role plays and 3D virtual reality interactive systems.

This unit of competency requires a significant body of knowledge, which will be assessed through questioning and the use of what-if scenarios both on the plant (during demonstration of normal operations and walk-throughs of abnormal operations) and off the plant

Critical aspects for assessment and evidence required to demonstrate competency in this unit 

Competence must be demonstrated in the ability to recognise and analyse potential situations requiring action and then in implementing appropriate responses. The emphasis should be on the ability to stay out of trouble rather than on recovery from a disaster.

Consistent performance should be demonstrated. In particular look to see that:

  • early warning signs of equipment/processes needing attention or with potential problems are recognised
  • the range of possible causes can be identified and analysed and the most likely cause determined
  • appropriate action is taken to ensure a timely return to full performance
  • obvious problems in related plant areas are recognised and an appropriate contribution made to their solution.

These aspects may be best assessed using a range of scenarios/case studies/what-ifs as the stimulus with a walk-through forming part of the response. These assessment activities should include a range of problems, including new, unusual and improbable situations, which may have been generated from the past incident history of the plant, incidents on similar plants around the world, hazard analysis activities and similar sources.

Context of and specific resources for assessment 

Assessment will require access to a process control system over an extended period of time, or a suitable method of gathering evidence of operating ability over a range of situations. A bank of scenarios/case studies/what-ifs will be required as will a bank of questions, which will be used to probe the reasoning behind the observable actions.

Method of assessment 

In all plants it may be appropriate to assess this unit concurrently with relevant teamwork and communication units. Consider co-assessment with appropriate operations competencies for the unit of plant.

In a major hazard facility, it may be appropriate to assess this unit concurrently with:

  • MSAOHS200A Work safely 

Guidance information for assessment 

Assessment processes and techniques must be culturally appropriate and appropriate to the oracy, language and literacy capacity of the assessee and the work being performed.

Range Statement

RANGE STATEMENT 

The Range Statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the Performance Criteria, is detailed below. Add any essential operating conditions that may be present with training and assessment depending on the work situation, needs if the candidate, accessibility of the item, and local industry and regional contexts.

Codes of practice / standards 

Where reference is made to industry codes of practice, and/or Australian/international standards, the latest version must be used.

  • unstable control of pressure, temperature level and flows
  • control equipment failure
  • process plant trips
  • change in atmospheric conditions (rain, temperature, wind, lightning)
  • emergency situations
  • loss of power/utilities.

Appropriate action 

Appropriate action includes:

  • determining problems needing action
  • determining possible fault causes
  • rectifying problem using appropriate solution within area of responsibility
  • following through items initiated until final resolution has occurred
  • reporting problems outside area of responsibility to designated person.

Health , safety and environment  (HSE )

All operations to which this unit applies are subject to stringent health, safety and environment requirements, which may be imposed through State or Federal legislation, and these must not be compromised at any time. Where there is an apparent conflict between Performance Criteria and HSE requirements, the HSE requirements take precedence.
