| 1.5 | Statutory and local authority requirements relating to the display of illuminated sign are identified and applied to planning. |
2 | Select and prepare LED modules. | 2.1 | LED system is selected according to job specifications and prepared for use. |
| 2.2 | Quantity of transformers required is calculated according to job specifications, and type of LED system is selected. |
3 | Fix LED system to sign. | 3.1 | Sign is checked to be free of damage, and is cleaned and allowed to dry. |
| 3.2 | LED modules are laid out and checked for completeness according to manufacturer recommendations. |
| 3.3 | LED modules are safely fixed to sign according to type of illumination required and manufacturer specifications. |
| 3.4 | Unused wires are safely capped or looped to avoid creating shadows on sign face. |
4 | Connect and test LED wires | 4.1 | Module wires are connected to transformers and regulated according to manufacturer specifications. |
| 4.2 | Module wires are tested to be fully functioning and any defects are identified and rectified. |
5 | Position and check sign. | 5.1 | Sign is mounted to surface or placed into position according to job requirements. |
| 5.2 | Sign is illuminated and checked for consistent distribution of light according to job requirements. |
| 5.3 | Inadequately lit areas of the sign and possible causes are identified and lighting is rectified according to job requirements. |
6 | Clean up. | 6.1 | Finished sign and surrounding surface area are cleaned and waste materials removed according to statutory and regulatory authority requirements. |
| 6.2 | Tools and equipment, including personal protective equipment (PPE), are cleaned, maintained and stored according to workplace requirements. |
A person demonstrating competency in this unit must satisfy all of the elements, performance criteria and foundation skills of this unit, and must select and install light emitting diode (LED) systems into three signs as follows:
two fabricated lower case ‘b’ in Helvetica font, measuring at least 600 mm high x 75 mm wide, and 100 mm deep and mounted to a white surface:
one must be face illuminated, with the face of the letter formed of opal acrylic and the back of the letter with a PVC foam backing
one must be halo lit, with the sides and face of the letter formed of non-illuminating cast acrylic and the back of the letter formed of clear acrylic
one freestanding back lit light box measuring up to 1800 mm x 300 mm x 100 mm, with an opal acrylic face.
