Puck Wear Surface Maintenance
The pucks that are used on the MagneMover LITE transport system may require being rotated
to make sure of even wear on the wear surfaces of the pucks. This is especially true for pucks
that are used in a transport system where all motion is in one direction, for pucks in a tandem
puck configuration, or for pucks that have a cantilevered or high inertia payload. For glide
pucks, if the wear surface wear is excessive (typically after greater than 16,000 km travel or 2
years) see Replace Glide Puck Wear Surfaces on page 81. For wheeled pucks, if the wear sur-
face wear is excessive (typically greater than 8,000 km travel for the lateral guide wheels and
bumpers, and 16,000 km travel for the suspension wheels) see Replace Wheeled Puck Wear
Surfaces on page 91.
NOTE: Rotating the pucks (vehicles) is only done for vehicles where the magnet array is
centered on the vehicle. For vehicles where the magnet array is not centered (for
example, the precision rail vehicle), the design of the vehicle determines if it is pos-
sible to rotate the vehicle.
1. Stop all motion on the MM LITE transport system.
2. Remove the pucks from the MagneMover LITE transport system (see Replace Pucks
on page 78).
3. Rotate the pucks 180°.
4. Replace the pucks on the MM LITE transport system (see Replace Pucks on page 78).
Cable Connection Inspection
1. Stop all motion on the sections of the MM LITE transport system to be inspected.
2. Verify that all cable connectors are fully seated and screws/locks are secured to
achieve good continuity.
3. Inspect all cables for restricting bend radii, excessive tension, or physical damage.
4. Return the MM LITE transport system to normal operation.
Hardware Inspection
1. Stop all motion on the sections of the MM LITE transport system to be inspected.
2. Turn off all MM LITE transport system components with accessible power controls.
3. Make sure that all motor stand hardware is secure.
