Description
Employability Skills
Learning Outcomes and Application This unit of competency defines the skills and knowledge required to determine control loop characteristics, monitor and record the operation of a control loop, localise the fault condition, and replace or repair the faulty condition.It applies to split architecture single/multiple loop control instrumentation that includes programmable logic controllers (PLCs), distributed control systems (DCS) and computer-based systems.Where fault-finding is required to electronic component level unit MEM18056 Diagnose and repair analog equipment and components and unit MEM18065 Diagnose and repair digital equipment and components, should also be selected as appropriate.No licensing, legislative or certification requirements apply to this unit at the time of publication.Band: BUnit Weight: 8
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

(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.

This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.

Historical trends include one (1) or more of the following:

supervisory control and data acquisition (SCADA)

charts

chart recorders and data loggers

equipment conditioning monitoring

An open and closed loop system includes:

final control elements

process measuring devices

converters

controllers

process signals

Relevant data includes one (1) or more of the following:

maintenance records

fault indicators

charts

error codes

operational symptoms

observation monitoring

consultation with appropriate personnel

Major components include one (1) or more of the following:

transducers

power supplies

removable circuit boards

sensor units

other like components

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.
