Introduction
This section provides a brief overview of the KMD-7001, 7002 and 7003 Direct
Digital Controllers. These units are intended for use with standard 1/2” round or
3/8” square damper shafts.
Note:
For installations using a 3/8” round shaft, you will need the HFO-0011 shaft
adaptor.
Review this material before you attempt to install the controller.

This section provides important instructions and guidelines for installing the
KMD-7001, 7002 and 7003 series controllers. Carefully review this information
prior to attempting installation.
Preparation
Prior to mounting the controller, the rotational limits must be set using stop pins.
These settings limit the shaft rotation in the clockwise (CW) and counterclockwise (CCW) directions. (Refer to Illustration 5.)

Illustration 5. Controller Stop Selections
To set the rotational limits:
1. Turn the controller over so you have access to the back.
2. Locate the two stop pins installed in the back of the unit. (You will find one
pin in a CCW setting and one in a CW setting.)
3. Identify the limits you wish to use.
The maximum amount of shaft rotation is 90°. Placing a stop pin in both 90°
slots allows the actuator the full 90° of travel. Placing a stop pin in any other slot
restricts actuator motion in the indicated direction (CW or CCW). Refer to
Illustration 6 for pin placement and travel. The first number represents the CCW
pin and the second the CW pin (CCW/CW).
