Mounting a Lexium™ MC12 Heavy-Duty Carrier

Overview

The following procedures describe the mounting of a Heavy-Duty carrier.

NOTE: Exposed or uninstalled carriers must have the protective cover of the drive magnets installed at all times. The cover is only removed at the time of carrier installation.

  • Carriers have strong local magnetic fields. Refer to Transporting the Lexium™ MC12 carriers.

  • The carriers have strong drive magnets and can attract metal objects that are in their proximity.

  • A carrier can move suddenly and fast due to magnetic attraction.

 WARNING
Strong MAGNETIC FIELDS
  • Keep persons with medical implants (for example, pacemakers or metal implants) or metallic body jewelry away from the carriers and segments with a minimum distance of 30 cm (11.9 in).
  • Always leave the protective cover of the drive magnets in place for all exposed or uninstalled carriers.
  • Do not put your hands or fingers between the carriers and segments.
  • Do not place metallic tools in the vicinity of the carriers and segments.
  • Do not place electromagnetically sensitive devices near the carriers and segments.
  • Do not place credit cards or electronic/magnetic media in the vicinity of the carriers and segments.
Failure to follow these instructions can result in death, serious injury, or equipment damage.

The carrier has two magnets which, together with the magnetic fields in the segments, move the carrier on the track. These two magnets are glued onto the carrier. A shock to the carrier can cause the glued-on magnets to flake off and the magnets can splinter.

In addition, the carrier has an encoder magnet. This can be demagnetized by improper handling, for example, if the magnets of another carrier come too close.

 WARNING
inoperable equipment
  • Handle the carrier with care.
  • Do not drop the carrier.
  • Do not strike the carrier.
  • Keep a minimum distance of 50 mm (1.97 in) between the encoder magnet and other magnets.
Failure to follow these instructions can result in death, serious injury, or equipment damage.

Mounting a Heavy-Duty Carrier

Before mounting, make sure that the lubrication pads are oiled. If the Heavy-Duty carriers are not oiled, relubricate the pads. For more information, refer to Filling the Lubrication Pads.

Step

Action

1

When mounting the carrier, ensure that the top guide rails are open.

Dismount one curved top guide rail and replace it with a mounting rail to push the carriers on the track.

2

Uninstall the protective cover of the drive magnets by sliding it up or down. Refer to Removing the Protective Cover of the Drive Magnets.

3

Grab the carrier with one hand at the top and with one hand at the bottom and do not place your fingers between the carrier and the segments.

4

Push the carrier with the top rollers onto the top guide rail. Make sure that the 4 rollers are properly positioned on the V-shaped guide rail.

NOTE: When the carrier gets near the segments, the magnetic force attracts the carrier to the track.

5

When the carrier is on the track, make sure that also the bottom rollers are on the V-shaped guide rail.

6

Verify whether the carrier can be moved by hand to be sure that the rollers are on track.
