Learning Outcomes and Application This unit covers the skills required to alter the control parameters of fluid power control systems by system modification; this includes the ability to assess system performance based on sound working knowledge of established principles, methods and procedures.System specifications are interpreted/understood from data sheets, circuit diagrams and flow diagrams. Corrections, modifications/alterations are undertaken to specifications to parts of the control system including software timers, gates, associated equipment, flow, ladder and logic diagrams. Fault finding of system hardware input/outputs includes input/output circuitry, cards, external sensors, limits, mnemonic coding and associated equipment. Service reports are prepared according to standard operating procedure. Programmable controllers include PLC and DCS or similar.Band: BUnit Weight: 6

Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment

A person who demonstrates competency in this unit must be able to modify fluid power control systems. Competency in this unit cannot be claimed until all prerequisites have been satisfied.

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

Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria, including required knowledge, and be capable of applying the competency in new and different situations and contexts.

Context of and specific resources for assessment

This unit may be assessed on the job, off the job or a combination of both. Where assessment occurs off the job, i.e. the candidate is not in productive work, an appropriate simulation must be used where the range of conditions reflects realistic workplace situations. The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team. The assessment environment should not disadvantage the candidate.

This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with modifying fluid power control systems or other units requiring the exercise of the skills and knowledge covered by this unit.

Method of assessment

Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways including direct observation, supervisor's reports, project work, samples and questioning. Questioning should not require language, literacy and numeracy skills beyond those required in this unit. The candidate must have access to all tools, equipment, materials and documentation required. The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials.

Guidance information for assessment

Submission Requirements

(add new lines for each of the assessment tasks)

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Look for evidence that confirms skills in:

reading, interpreting and following information on written job instructions, specifications, standard operating procedures, charts, lists, drawings, circuit and ladder diagrams and other applicable documents

planning and sequencing operations

checking and clarifying task-related information

identifying, recording and correcting deviations of control software program from specification

modifying control system software/program and recording modifications

the procedures for reporting service undertaken on control systems

any trends and probable causes, evident in the data collected and collated

reasons for recommended improvements

safe work practices and procedures

hazards and controls associated with modifying fluid power controls, including housekeeping

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. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Control system

PCs, programmable controllers, DCS, relay logic (electric-hydraulic-pneumatic) etc.

Modifications

Modifications covered by this unit are changes to fluid power control systems that lead to desired changes in system performance

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
