Maintenance Schedule

Perform the following maintenance tasks after delivery or long storage:

Interval¹	Action
After delivery	Fill the lubrication reservoirs of the carriers. Refer to Lubrication.
After delivery, every 1000 km (621 miles) or within the first two months of service life	Verify the Lexium™ MC12 multi carrier by visual inspection for any damage or missing parts, especially for moving parts and parts at risk for collisions such as mounting elements.
After ≥ two years of storage	Verify the lubrication pads of the carriers and replace if necessary. Refer to Replacing Parts.
1 The distances referred to are for one carrier. The performance of your system may differ.

Perform the following maintenance tasks within the stated intervals.

NOTE: The intervals in the following table are only guidelines. The intervals can be adjusted depending on your application and the environmental conditions (track length, number of carriers, motion profile, temperature, and so on).

Interval¹	Action
Every 1000 km (621 miles) of operation	Clean the Lexium™ MC12 multi carrier if necessary. Refer to Cleaning. Verify that the floating bearing of the lower carrier rollers moves freely in axial direction. Clean if necessary and make the rollers run smoothly. Refer to Cleaning the Carrier Rollers. Verify the lubrication pads of the carriers for dirt and clean if necessary. Verify the lubrication pads of the carriers for wear and replace them if necessary. Refer to Replacing Parts. Lubricate the carriers. Refer to Lubrication.
Every 4000 km (2485 miles) of operation	Clean the Lexium™ MC12 multi carrier. Refer to Cleaning. Verify the covers of the segments and the drive magnets of the carriers for dirt and magnetic abrasion. Clean the covers and the magnets and remove the magnetic abrasion if necessary. Refer to Removing Particles from the Magnets. Verify the carrier rollers for dirt and clean if necessary. Verify the lubrication pads of the carriers for dirt and clean if necessary. Verify the area of encoder magnets of the carriers for dirt, and clean if necessary. Verify the rails for dirt, and clean if necessary. Verify the Lexium™ MC12 multi carrier by visual inspection for any damage or missing parts, especially moving parts and parts at risk for collisions such as mounting elements. Verify the drive magnets of the carriers for damage. The drive magnets cannot be replaced individually. Replace the plate with the two magnets as a whole if necessary. Refer to Replacing the Drive Magnets of the Carrier. Verify the encoder magnets of the carriers for correct seating and for damage. Adjust or or replace if necessary. Refer to Replacing the Encoder Magnet of a Carrier. Verify the rails for wear or damage and replace them if necessary. Verify all parts for bolted connections.
Every 20,000 km (12,427 miles) of operation	Verify the carrier rollers for wear and replace the carrier rollers if necessary. Refer to Replacing the Rollers of a Carrier.
1 The distances referred to are for one carrier. The performance of your system may differ.

Perform the following maintenance tasks if your carriers have exceptional movement profiles:

Movement profile	Action
Reversing movements in which the carriers travel a distance of less than 200 mm (7.88 in).	If a distance of less than 200 mm (7.88 in) is travelled, perform a lubrication run after 20,000 traverse cycles or earlier. NOTE: Sufficient lubrication during reversing movements can only be reached if the carriers travel a distance of at least 200 mm (7.88 in).
