M9484 motor by 0.75 inch to match that of the M941 motor. This is required on all valve linkage applications,
Q607
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

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 appli­cations 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 sepa­rately (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
should be no more than
60”.
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.

WIRING BOX
When used with liquid-tight conduit connectors, the wiring box provides NEMA 3 weather protection for the motor. The box also provides knockouts for wiring conduits and encloses terminals. The wiring box, standard with replace-
ment motors, is required for housing an internal trans-
former, internal auxiliary switches or Series 70 Interface
Modules.

STROKE SEl-lING
On M94XXD,E,F motors, stroke is field adjustable and can be set from 90” to 160”. Motors are shipped in 90” position. In order to set stroke, both mechanical and elec­trical adjustments are required. The mechanical adjust-
n
ments (cams) establish the full open (clockwise, viewed from the power end) and full closed (counterclock­wise

)
positions of the motor shaft. The electrical adjustment (trim pot) provides sufficient total stroke angle to ensure that cams will actuate both limit switches.

AUXILIARY SWITCHES
The auxiliary switches in ated by adjustable cams. The cams are mounted on the motor shaft at the power end of the motor. The settings of
the cams determine the point in motor shaft rotation at which the auxiliary equipment will be switched on or off. These cams can be set to actuate switches at any angle within the stroke of the motor. Also each cam provides a fast rise portion for switching (1

MODULATlNG
The potentiometers, one in the controller and one in the motor, along with resistor network, form a bridge circuit. As long as the value of the controlled medium remains at the controller set point, the circuit is balanced, and the motor does not run.
When the value of the controlled medium changes, the potentiometer wiper in the controller is moved, which
unbalances the bridge circuit. This unbalance is amplified,
and energizes direction necessary to correct the change in temperature or pressure. The motor turns the feedback potentiometer to rebalance the circuit and stop the motor.

These motors are designed for use in series 90 propor­tioning control circuits employing a 135 ohm series 90 controller. Series 90 high or low limit controls or manual
minimum position potentiometers may also be used in the control circuit.
The M9484 can also be used with some electronic
mA
controllers which provide a 4-20 necessary to use a resistor kii (4074EED for controlling up to 6 motors) or Q7230 Interface Module to interface to the 4-20 mA source.
The standard series 90 controller has R, W, and B
terminals. As the controller reduces Rto W resistance, the
motor will drive closed (CCW as viewed from the power end).

*
The motor operates the damper or valve properly.
l The motor responds properly to the controller.
Inspect the motor, linkage, and valve or damper to see that all mechanical connections are correct and secure. In damper installations, the
pushrod
should not extend more than a few inches past the ball joints. Check to see that there is adequate clearance for the linkage to move through its stroke without binding or striking other objects.
Check to see that cams operate the auxiliary switches,
if used, at the desired point of motor rotation.
NOTE: Motors are shipped in the fully closed position (the
limit of counterclockwise rotation as viewed from the power end of the motor) with the stroke set at

NOTES:
a
Ensure motor transformer is sized properly. If a common transformer is used to power multiple motors, ensure power
input is in phase with all motors.

Motors may operate in Series 90 or two-position control applications. However, checking voltage between terminals

to B and R to W is necessary to confirm proper operation in electronic (W973, 4 to 20 mA etc.) applications.
