PRE-INSTALLATION
Inspection
Visually inspect the package for damage. If damaged, notify
the appropriate carrier immediately. If undamaged, open the
package and visually inspect the device for obvious defects.
Return damaged or defective products.

General Instructions
INSTALLATION
Caution:
1. Installer must be a qualified, experienced technician.
2. MM-400/500 Series and MMR-400/500 Series General
Instru
ction sheets contain specific information on
modular motor installation.
3. Avoid locations where excessive moisture, corrosive fumes or vibration are present. AM-230 Series linkages are intended for mounting only to the MM-400/500 Series and MMR-400/500 Series Modular Motors.
4. Damper rod (AM-125-XXX) should be: a. Long enough for easy adjustment. b. Short enough to be rigid, providing good damper
response.
Required Installation Items
• Tools (not provided):
Appropriate screwdriver and wrenches.

Figure-1 Crank Arm/Hub AM-230.
Figure-2 Crank Arm Mounting to Motor Output Shaft.
1. Align the modular motor output shaft to the shaft hole in the motor crank arm/hub (AM-230) and insert the crank arm/hub (AM-230) on the motor output shaft.
2. Finger tighten the motor crank arm/hub screws at this phase of the installation.
Note: Do not install retainer clip until adjustments are
complete.
3. Insert the damper crank arm on the damper shaft
(AM-113 for 1/2" dia. shaft). Position the damper blades
in the position required with the motor in CCW
(counterclockwise) position (as viewed from the “Load” or
“Load, Normally Closed-CCW Spring Return” end).
Note: The crank arm must be firmly installed on the motor
output shaft and rest against the output shaft shoulder.
4. Finger tighten the damper crank arm screws only at this point of the installation.
5. Install a ball joint linkage (AM-132) as close as possible to motor output shaft.
6. Install a ball joint linkage (AM-132) at the positions shown on the damper crank arm (see Figure 3) - adjust after linkage is assembled and the motor is run through its stroke.

Two Position Damper Ball Joint Position on Damper
Crank Arm (See Figure 3 and Table 1)
Set the ball joint on the damper crank arm as indicated in
Table 1. the damper will be completely open or completely closed if required by a two position controller.
Proportional Damper Ball Joint Position on Damper
Crank Arm (See Figure 3 and Table 1)
Set the ball joint on the damper crank arm (see T able 1).
A damper set to open at 60° will allow approximately
96% of the maximum air flow through the damper. Further damper opening will pass little, if any, additional air.
Motor shaft rotation of 160° and a maximum damper
shaft rotation of 60° will provide the best possible air flow
control by the damper.
7. Assemble the pushrod to the ball joints. Finger tighten the ball joint setscrews.
ADJUSTMENTS
See Figure 5.
1. Position the damper midstroke.
2. Slide the motor crank arm off the output shaft.
3. With the motor output shaft in line with the motor crank
arm rotate the motor crank arm around the motor output
shaft axis and the damper crank arm around the damper
shaft until both crank arms are perpendicular to the
imaginary line between the motor and damper shafts.
4. Tighten the set screws on the damper crank arm and ball joint.
5. With the motor crank arm still off the output shaft: a. Rotate the motor crank arm CW (clockwise) through
the remainder of the motor stroke.
