Qualification -
Unit of Competency MEM27025 - Maintain, diagnose and rectify fluid power controls in mobile equipment
Description
Employability Skills
Learning Outcomes and Application This unit of competency defines the skills and knowledge required to install and repair and/or rectify fluid power controls used in mobile equipment applications. It applies to hydraulic fluid power systems control circuits and may also apply to mobile equipment using pneumatic systems. Where pneumatic controls are also to be maintained, relevant pneumatic units should also be selected.It covers fault finding of fluid power systems control circuits, maintaining and repairing or replacing system control components, and checking and adjusting the operation of fluid power system controls. System circuit/components are identified, traced, inspected and operational function is assessed and verified using fluid power principles to predetermined specifications interpreted from data sheets and circuit diagrams. No licensing, legislative or certification requirements apply to this unit at the time of publication.Band: BUnit Weight: 6
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

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.

Fluid power system controls include one (1) or more of the following:

fieldbus system control unit

integrated or separate measurement/testing/data logging equipment

electronic proportioning and bus systems

proportional and servo controlled valving and the associated electronic amplifiers and drivers

joystick

controller variable and/or digital inputs and outputs

sensors

digital/analog transducers and proximity switches

transducers

timers

counters

ancillary equipment

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.
