Modular Magnet Track
Installation	Refer to Figure 2-3. Some magnets are provided in modular segments. This is the
	recommended procedure to install these modular magnet track sections.
	Note: It is recommended that rubber coated tool handles be used to reduce injury
	(pinching fingers etc.) and protect the surface of the magnets.

1.Bolt the coil assembly onto the underside of the slide (carriage). Ensure the leads extend in the proper direction.

2.Install the magnet track on the base–plate adjacent to or between the linear bearing. Magnet track ends should not oppose each other.

Place a 0.030″ ± 0.005″ thick non magnetic shim on the magnet track. The shim thickness must be equal to the recommended air gap (space between the coil assembly and the magnet track).

3.Hold the slide with a firm grip and move it over the magnet track section/shim.

Note: The slide will be drawn forcefully towards the magnet track and may overshoot the rails if not held firmly.

Check the space between the shim and the coil assembly. If the space between the shim and the coil assembly is large, uniformly loosen the mounting screws allowing the coil assembly to be fully and evenly lowered onto the shim. Insert another shim thick enough to fill the gap between the coil assembly and the slide, see Figure 2-4. Tighten the mounting screws once again.
