Insert the two screws previously removed to hold the hook-lowering block in
place.
7. Reinstall the latching mechanism cover.
See Installing Latching Mechanism Cover on page 158.
Light Discs
The two light disc assemblies and their controllers are single units, so replacing a controller
also replaces all of the lights on that side of the platform.
1. Remove the side cover, on the side that needs the light disc assembly replaced.
Refer to Removing and Installing LD Platform Cart Transporter Covers on page 158.
2. Unscrew the four screws holding the light disc PCA to the side cover.
Retain the screws and round cover for installing the new assembly.
3. Remove the light disc PCA.
4. Screw the new assembly and retained round cover to the side cover, using the screws
retained from the old assembly. The PCA is keyed so that it can only be installed in one
orientation.
5. Reinstall the side cover, connecting the cable to the new light disc PCA.
6. Dispose of the old light disc PCA according to local and national regulations con-
cerning electronic components.
Operator Panel
The Operator panel will typically be located on a user-supplied payload structure, so the
removal and replacement of this will vary from one AMR to another. It plugs into the HMI
Panel connector on the core.
Wheels and Tires
The wheels and tires should be checked every 3 months. If they show signs of cracking, excess-
ive wear, or any damage they should be replaced. Refer to the following figure.
