Installation

CAUTION

Do not install a magnet assembly that is shorter than the physical travel of the actuator. Loss of control will result from the

magnet assembly moving outside the range of the index mark in the feedback slot of the DVC6215 housing.

4. Using the alignment template (supplied with the mounting kit), position the magnet assembly inside the retaining

slot.

5. Align the magnet assembly as follows:

For air‐to‐open actuators (e.g. Fisher 667) vertically align the magnet assembly so that the center line of the alignment

template is lined up as close as possible with the upper

extreme of the valid travel range on the magnet assembly. The

magnet assembly should be positioned so that the index mark in the feedback slot of the DVC6215 housing is within

the valid range on the magnet assembly throughout the range of travel. See figure 2‐10.

For air‐to‐close actuators (e.g. Fisher 657) 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 in the feedback slot of the DVC6215 housing is within

the valid range on the magnet assembly throughout the range of travel. See figure 2‐11.

6. Tighten the fasteners and remove the alignment template.

Note

Use a flat end hex key to tighten the mounting assembly fasteners to a torque of 2.37 N•m (21 in•lbf) for 4 mm screws, and

5.08 N•m (45 in•lbf) for 5 mm screws. While tightening the fasteners using the hex key should be sufficient, blue (medium) thread

locker may be used for additional security.
