1. Unit Assessment Plan Overview Competency Standard Unit (CSU)
UEENEEE137A - Document and apply measures to control OHS risks associated with electrotechnology work
CSU Descriptor
This unit covers identifying occupational health and safety hazard and risks and documenting control measures. It encompasses identifying workplace hazards, assigning levels of risk, developing control measures to eliminate and/or mitigate risks, reviewing risk control measures and maintaining documentation of hazards, risk control measures and their application in accordance with compliance procedures.
Purpose of UAP
The purpose of the UAP is to provide the specification for the evidence gathering tools to meet the competency standard unit for the CIII in Electrotechnology Electrician qualification.
Sequence Before undertaking this Unit Assessment Plan a learner is to have met the:

2. Carrying Out the Unit Skills Test
This skills test requires you to undertake and document a hazard and risk assessment on a practical work area such as a workshop or electrical installation facility
You will be required to identify a number of hazards within the workshop or facility.
For each identified hazard, use the attached Workshop Hazard, Risk and Control documentation sheet to document your findings.
The Workshop Hazard, Risk and Control documentation sheet has 5 columns. These are:
Column 1 - Briefly describe the identified hazard
Column 2 – State the associated risk from the hazard
Column 3 – Determine the risk level using the enclosed Risk Matrix
Column 4 – List one or more control measures to reduce the risk level
Column 5 – For each control measure, indicate the level on the hierarchy of control (there may be a combination of control hierarchy)
Your assessor will provide you with any necessary apparatus, tools and test equipment needed to complete the task.
At each checkpoint, have your assessor check your results.

Q1 Q. What is the function of electrical interlocking contacts in a DOL motor reversal circuit?
A. To prevent the forward and reverse contactors energising at the same time, which would cause a phase to phase short circuit.
All correct
Q2 Q. Why must field input devices, such as N/C limit switches or stop buttons be programmed as ‘examine on’ in a ladder logic diagram?
A. To ensure that the input from the N/C contact is interpreted correctly in the ladder logic diagram, in order to switch an output when the N/C contact opens.
All correct
Q3 Q. In a star-delta starter;
a. What is ratio of the starting current when the motor is started in star, compared to the same motor started in delta?
b. What is ratio of the starting torque when the motor is started in star, compared to the same motor started in delta?
A. a. Istar = 1/3 Idelta
b. Tstar = 1/3 Tdelta
All correct
Q4 Q. Why is it necessary to provide a zero-speed switch when plug braking is used on a three-phase motor?
A. To prevent the motor reversing at the end of the braking period.
All correct

Q5 Q. Explain why a VF drive must adjust the output voltage for each change in output frequency.
A. Motor XL is directly proportional to motor frequency. As frequency is reduced, XL is also reduced and motor current increases. Therefore, a VF drive output voltage is adjusted to ensure motor current is not too high as the frequency is reduced.
All correct
Q6 ‘Unplanned events question’ – (The text for this question will be provided by your assessor at the time of assessment.) Write the question and your answer in the space below. Q. A star-delta starter starts correctly in star when the start button is pushed, but fails to switch over to delta. List 4 possible faults in the control circuit that could cause this to occur. A. Faulty timer relay, incorrect timer relay selected, O/C contact in the control circuit, O/C delta contactor coil, S/C auxiliary contact in star contactor, mechanical fault in star contactor to prevent its release, mechanical fault in delta contactor to prevent it closing
