This procedure applies to the AON-M2 2020 only.
Required Tools and Equipment
- Eye protection
- Close-fitting gloves
- 90° long nose pliers
- Stool for sitting comfortably
- Work light
Required Consumables and Supplies
- Blue halogen bulb G5.3, 230V, 50W - BDC7A7BA
Preparation
Maximize the available work space inside the machine:
Move the gantry and toolheads to the back and sides of the machine.
Lower the bed from its home position by 200 mm.
The halogen bulbs are powered with 220V. Make sure to unplug the machine before replacing the halogen bulbs. Failure to unplug the machine before replacing the halogen bulbs can cause electric shock or damage to the machine.
Power off the machine using the switch located at the back of the machine and then unplug it from the power source.
Remove Halogen Bulb
The halogen bulb and metal surfaces close to the lights will be very hot if the lights were recently used. Allow the area to cool sufficiently to ensure safe handling. Failure to allow sufficient cooling time can cause burns.
Do not remove the halogen bulb housing when replacing the halogen bulbs. Removing the halogen bulb housing can cause damage to the machine’s electrical wiring. Damage to the electrical wiring can cause electric shock or damage to the machine.
Remove the light cover from the housing.
Remove the burnt halogen bulb using the 90° long nose pliers to gently grasp the base of the bulb and tug the bulb straight out of the fixture. Be careful not to break the glass base of the bulb.
The halogen bulbs are made of glass and could shatter if mishandled. Be sure to wear appropriate gloves and exert caution while replacing the halogen bulbs.
Burnt halogen bulbs should always be disposed of according to local regulations.
Install Halogen Bulb
Do not touch the halogen bulbs with your bare hands. The salts and oils from your skin will damage the bulb and cause the heat to concentrate. This can significantly reduce the life of the bulb or even worse cause it to shatter.
Wearing clean gloves, align the pronged end of the new halogen bulb with the light socket and gently press it into position.
Make sure the metal clip is correctly positioned on the light cover.
Place the end of the light cover without a clip in the metal bracket on the housing and press the entire cover towards the lightbox until you hear a click.
Leave the Automatic Light Shutoff set on to improve the lifespan of the bulbs.
Refer to AON-M2 2020 Chamber Light Shutoff Feature.
Test
Plug the machine into the power source and switch it on. When successfully installed, the light will immediately turn on.
