FIG. 2-LIMITS OF MOTOR ROTATION.

ADAPTER BRACKET

 Adaptor Bracket, positioned between the

motor and the equipment, raises the shaft height 
M9484 motor by 0.75 inch to match that of the M941 motor.

This is required on all valve linkage applications, 

External Auxiliary Switch applications, and on some

damper linkage applications (either to provide clearance
for the crank arm to rotate through the downward position,

or to allow the damper linkage to reach the shaft).

To mount the motor with the bracket:

1. Mount the bracket to the equipment with existing or

standard bolts.

2. Mount the motor to the bracket using the bolts pro-

vided into the threaded holes of the bracket (see Fig. 3).

For valve linkage applications, the bracket should first

be mounted to the linkage (see Fig. 4). The bracket then
provides a convenient base on which the motor can be
positioned. After the motor shaft is aligned to the linkage,

it can then be attached to the bracket with the 4 bolts

provided. These bolts go through the inner set of holes in

the motor 

 and into the threaded holes of the bracket.

DAMPER LINKAGES

A 220738A Adapter Bracket is packed with replace-

ment motors. Use of this bracket is optional for many

damper applications but may be needed in damper appli-

cations requiring the crank arm to rotate through the

bottom plane of the actuator. If the bracket is not used in a

replacement application, the damper linkage will have to

be adjusted to the new shaft position.

The motor comes without a crank arm. The crank arm

is included in the Q605 linkage or may be ordered sepa-

rately (see Accessories).

For detailed instructions on the assembly of specific

linkages, refer to the instruction sheet packed with each

linkage. In general, however, check the following points of
operation when installing a motor and linkage.

1. Linkages for valves and louver type dampers should

be adjusted so that the damper or valve moves through
only the maximum required distance when the motor

moves through its full stroke.

2. With modulating control, maximum damper 

opening

should be no more than 

 Little additional airflow is

provided beyond this point.

3. The motor must be stopped at the end of its stroke

by the limit switch and must not be stalled by the damper

or valve. The motor will be damaged if it is not permitted to

complete its full stroke.
