Vertically align the magnet assembly so that the center line of the alignment template is lined up as close as possible
with the lower
extreme of the valid travel range on the magnet assembly. The magnet assembly should be positioned
so that the index mark on the pole pieces (back of the DVC6200 housing) is within the valid range on the magnet
assembly throughout the range of travel. See figure 9.

Note
Use a flat end hex key to tighten the magnet assembly fasteners to a torque of 2.37 N•m (21 lbf•in) for 4 mm screws, and
5.08 N•m (45 lbf•in) for 5 mm screws. For added security, especially in vibrating services, blue (medium) threadlocker may be
used on the fasteners.
