Mounting
Use the following guidelines for proper motor mounting:
• Always install motors with the crankshaft horizontal.
• Mounting flanges extending from motor housing base are
drilled for 6.4 mm machine screws or bolts.
• Motors are shipped from the factory in their normal position:
— Normally closed models are shipped at the counter-
clockwise rotation limit (viewed from the power end).
NOTE: Refer to Fig. 1 for graphical representation of
fully-open and fully-closed positions.
Adapter Bracket
The 220738A Adapter Bracket, positioned between the motor
and the equipment, raises motor shaft height by 19 mm to
match that of previous Modutrol Motor models.
The following applications require this bracket:
• Q607 External Auxiliary Switch.
• Damper linkage applications require added clearance to
allow:
— Crank arm rotation through the downward position.
— Sufficient damper linkage to reach the motor shaft.
• All valve linkages except the Q5001.
NOTE: When the bracket is not used in a replacement

M18993
For valve linkage applications (other than the Q5001):
1. Mount the bracket to the linkage.
2. Position the motor on the bracket to align the motor
shaft with the linkage.
3. Attach the motor to the bracket with the four bolts
(provided).
NOTE: The bolts go through the motor flange holes
and into the threaded holes of the bracket.
Damper Linkages
Use of the 220738A Adapter Bracket is optional for many
damper applications. This bracket or a 221455A Crank Arm
might be needed in applications that require the crank arm to
rotate through the motor bottom plane.
NOTE: Replacement applications where the shaft height
changes require damper linkage adjustment.
The motor is supplied without a crank arm. The crank arm is
included in the Q605 Linkage or can be ordered separately
(see Accessories in the Specifications section).
For detailed instructions on specific linkage assembly, refer to
the instruction sheet packed with the linkage. In general,
however, check the following points of operation when
installing a motor and linkage:
— The motor must be permitted to complete its full stroke.
Damper or valve induced motor stall can damage the
motor. Adjust valve and louver-type damper linkages so
that the damper or valve moves through no more than the
maximum required distance when the motor moves
through its full stroke.
— Maximum damper opening should be no more than 60°.
Little additional airflow is provided beyond this point.
— Do not exceed the motor ratings in any installation.

STROKE
POTENTIOMETER
Auxiliary Switches
The auxiliary switches are spdt switches that are actuated by
adjustable cams. The cams are factory-mounted on the motor
shaft at the power end of the motor. The cam settings
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 the switches at any angle within the
motor stroke.
NOTE: Series 2 Motors are shipped with auxiliary switch
cams that permit acceptance of 220736A,B Internal Auxiliary Switch Kits. Refer to Form no. 632228 for 220736A,B Installation Instructions.
For auxiliary switch wiring, see Fig. 12.
With a 1° differential, the N.C. switch contacts make and the
N.O. switch contacts break on a counterclockwise (closed)
rotation. If a 10° differential is chosen, the operation is
reversed, the N.O. switch contacts make and the N.C. switch
contacts open on a counterclockwise (closed) rotation.
NOTE: When the slow-rise portion of the cam is used,
the switching differential is approximately 10° of
rotation. When the fast-rise portion of the cam is
used, the switching differential is approximately
1° of rotation. Do not use the fast rise portion of
the cam if fast cycling of auxiliary equipment is
undesirable.

Auxiliary Switch Adjustment
Adjustable cams actuate the auxiliary switches. These cams
can be set to actuate the switches at any angle within the
stroke of the motor. Select switch differential of 1° or 10°.
NOTES:
— Auxiliary switches can only be added to motors
that include auxiliary switch cams. (These cams
cannot be field-added.)
— Normally Closed motors are shipped in the closed
position (counterclockwise, viewed from the
power end) with auxiliary switch cams set to
operate switches 30° from closed position with a
1° differential. With motor in fully closed position,
the N.C. auxiliary switch contacts are closed.
— See Fig. 12 (or the auxiliary switch Instruction
Sheet) for auxiliary switch wiring.
— Motors are shipped with auxiliary switch cams.
To rotate a cam, insert a small screwdriver (1/8 in. or 3 mm
blade) through the junction box into the slot on the cam and
move the screwdriver at the top of the handle. The inner cam

actuates the right switch and the outer cam actuates the left
switch (viewed from the power end). Refer to Fig. 11. Each
division on the cam represents 15° of motor rotation.
1. Turn off the power and remove the junction box cover.
2. Determine the amount of shaft rotation, in degrees,
desired before the switch is to be energized.
3. Note the cam slot positions.
4. With a screwdriver, rotate the cam to the desired angle
for switching action. As noted above, each cam division
represents 15° of motor rotation. Therefore, if 60° of
motor rotation is desired before the switch operates,
rotate the cam four divisions from the reference point.
5. Turn on the power.
6. Check for proper switch differential and switching of
auxiliary equipment by driving the motor though full
stroke (in both directions). If necessary, repeat steps 3
and 4 until correct switching action is obtained, turning
off the power before readjusting the cam.
7. When adjustments are complete, replace the junction
box cover.

SERIES 41 AND 81 MODUTROL IV™ MOTORS
OPERATION AND CHECKOUT
Operation
In an operational circuit, a single-pole, single-throw controller
or fan starter (line voltage for Series 41, or low voltage for
Series 81) is wired in series with the motor circuit. When the
controller switch closes, the motor is energized and runs to
the end of its stroke. When the motor reaches it full stroke, it
holds this position as long as it is energized. When the
controller opens, the spring returns to the starting position.
Checkout
After the installation is complete, check the entire system for
the following points of operation:
• Motor operates the load properly.
• Motor responds properly to the controller.
• Motor returns to starting position when power is
interrupted.
Damper Application
1. Check the entire motor-damper linkage to ensure that
the mechanical connections are secure and properly
made. Be certain the ball joint on the damper crank arm
is properly placed to give the required amount of travel.
2. Energize the motor and run it to the end of its stroke.
Check the damper linkage while the motor is running to
see that there are no loose or binding connections.
3. If the motor does not run, check the control circuit for an
open or short, the presence of power, and voltage at the
motor. Voltage at the motor must be at least 85 percent
of the rated voltage (specified on nameplate.) Ensure
that the maximum motor net load is not exceeded.
4. Interrupt the power to de-energize the motor and allow
the spring to return the motor to the starting position. If
the motor does not return, check to ensure that power is
actually interrupted and that the return load is not
exceeding the rated motor load.
Valve Application
1. Check entire motorized valve assembly to ensure that
the mechanical connections (among motor, linkage, and
valve) are proper and secure. Be certain that the linkage
is adjusted according to the linkage instructions. Leave
the linkage cover off until the checkout is completed.
2. Be certain the load does not exceed the motor rating.
When using a Q5001 Linkage, no lubrication is
required. Install the plastic washer on the motor shaft
between the motor and cam to avoid motor binding and
stalling. Check to ensure that the linkage spring
compression is within the limits specified in the Q5001
Installation Instructions.
3. Energize the motor by setting the controller so that its
contacts close.
NOTES:The motor should start and run smoothly,
moving the valve stem to the opposite end of
its stroke. If this is not the case:
—Ensure there is power to the motor.
—If there is not power, check the controller
circuit for open or short circuits.
—If the trouble still cannot be found, measure
the voltage at the source.
—Line voltage must be at least 85 percent of
rated voltage stamped on motor nameplate.
4. De-energize motor by resetting the controller so its
contacts open, or remove one wire from a controller
terminal. Spring power should return the valve to normal
position. If this does not happen, check the linkage for
binding, or in the case of normally closed valves, check
for fluid pressure in excess of the close-off rating.
5. Replace the linkage cover.
REPLACEMENT
Damper Application
1. Turn off power and remove wiring from the old motor.
2. Remove crank arm from the old motor shaft and remove
the old motor.
3. Check to determine whether or not the mounting
bracket is needed. If the linkage can reach the new
motor lower shaft position and the crank arm has
clearance for the necessary rotation, then the bracket is
not required. Use the 220738A Adapter Bracket or the
221455A Crank Arm if the crank arm must rotate
through the motor bottom plane.
4. If no bracket is required, mount the new motor directly to
the equipment and refer as necessary to Installation,
Settings and Adjustments, and Operation and Checkout
sections of these instructions.
5. If the bracket is required, refer to the Adapter Bracket
section and see Fig. 3 in addition to the Installation,
Settings and Adjustments, and the Operation and
Checkout sections of these instructions.
6. Use old mounting bolts to mount the new motor.
7. Mount the damper crank arm and linkage to the shaft of
the new motor.
8. Use the Checkout procedures to test proper adjustment
of the crank arm and linkage.
Valve Application
When replacing a motor in a valve application that has a
Q100, Q601 or Q618 Linkage, it will be necessary to use the
220738A Adapter Bracket provided to raise the motor shaft to
the same height as that of the old motor. In valve applications
that have a Q5001 Linkage, the 220738A Adapter Bracket is
unnecessary. Ensure motor stroke is 160° to operate
Honeywell V5011 Two-way or V5013 Three-way Valves.
