MATERIAL CLAMP LUBRICATION
The material clamps located on each pallet should be cleaned and lubricated at least weekly. To clean a clamp,
remove the cap screw and clamp hook, then wipe the clamp assembly clean and lubricate with a coat of light oil
(Ex. SAE20 Non-detergent).
MAGNETIC TRACK MAINTENANCE
A very powerful magnetic eld surrounds the
magnet track. Keep all metal (steel) tools away
from this track.
The linear motor drive system consists of a moving linear motor coil and a stationary magnet track. The motor
coil is suspended approximately 0.015 inch (0.38 mm) above the surface of the tape covering the magnet track.
The tape protects the magnets and provides a wear surface for scraper blades to ride on. The scraper blades
push debris on the magnet track toward the ends of travel.
Do not remove the X Read head to clean the white scraper blade at front of linear motor.
Clean the tape surface every three months. Pull back the bellows and wipe the entire magnet track surface
with a lint-free cloth. Wipe debris toward the extremes of travel and then remove the debris. A mild water-based
cleaner can be applied to the cloth. Do not pour cleaning solution on the tracks. Remove any excess grease
from the linear bearing rails. Use care around encoder scale.
Check the scraper blades for wear and proper function twice a year. The blades must slide freely within the
guide slots on both ends of each linear motor (two X-axis motors and one Y-axis motor).
If the blades do not slide freely, clean the guide area and/or replace the scraper blade. Also, check the bottom
of the scraper blade. It must be at, free of gouges, and not excessively worn. To check wear, measure the
distance from the bottom edge to the small screw (centerline). Replace scraper if this distance is less than .125
inch (3.2 mm).
If a squeaking noise develops between the magnet track and scraper blade, a bonded dry Teon spray (CI P/N
#921916) can be applied to the magnet track.
PALLET DRIVE MAINTENANCE
CHAIN DRIVE TENSION ADJUSTMENT
Check chain drive tension periodically and adjust if necessary. Follow this procedure to adjust chain tension.
See Figure 9-5.
1. Move the pallet into the load frame and turn off the main power disconnect.
2. Use a 3/4 inch wrench to loosen the (3) motor mount assembly bolts on the inside of the main frame.
3. Using a 3/4 inch wrench, turn the tensioning bolt to adjust tension in the chain and cable assembly. Tighten
the bolt until the cable does not contact the plastic guide block at the main frame end of the load frame.
4. Use a 3/4 inch wrench to tighten the (3) motor mount assembly bolts on the inside of the main frame.
