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).
— Normally open models are shipped at the clockwise
rotation limit, (viewed from the power end).
NOTE: Refer to Fig. 2 for graphical representation of
fully-open and fully-closed positions.
Fig. 2. Motor shaft positions at stroke limits
(viewed from power end).
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
application, the damper linkage can require
adjustment for the new shaft position.
To mount the motor with the bracket:
1. Mount the bracket to the equipment with existing or
standard bolts.
2. Using the provided bolts, mount the motor to the bracket
threaded holes. See Fig. 3.
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
A 220738A Adapter Bracket is packed with TRADELINE
motors. Use of this 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.
— Do not turn the motor shaft manually or with a wrench.
This damages the motor.
Valve Linkages
Use the 220738A Adapter Bracket with the Q100 Linkage in
all valve applications. The 220738A Adapter Bracket is not
required with the Q5001 Valve Linkage (see Fig. 4).

Wiring
CAUTION
Electrical Shock or Equipment Damage Hazard.
Can shock individuals or short equipment
circuitry.
Disconnect all power supplies before installation.
Motors with auxiliary switches can have more than
one disconnect.
IMPORTANT
All wiring must agree with applicable codes,
ordinances and regulations.
Make sure that the voltage and frequency stamped on the
motor correspond to the power supply characteristics.
Fig. 5 shows the motor terminals (quick-connects located on
top of the printed circuit board). Wiring compartment access is
gained by removing the four screws from the wiring box top
and lifting off the cover.
See Fig. 6 through 10 for typical system wiring. Fig. 12 shows
auxiliary switch connections.
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 is required for housing an internal
transformer or internal auxiliary switches.

Fig. 11. Stroke adjustments.
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: 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.
Switching action is different depending on whether 1° or 10°
differential is chosen. See Table 3.
Fig. 12. Auxiliary switch schematic.
WARNING
Fire or Explosion Hazard.
Incorrect auxiliary switch wiring can allow the
burner to come on at high fire causing severe
injury or death.
Check auxiliary switch wiring and cam adjustment
before turning on the system.
Watch controlled equipment through a complete cycle.
Shut the system down immediately if switches do not
sequence the equipment correctly.
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°.

CAUTION
Equipment Damage Hazard.
Can damage the motor beyond repair.
Never turn the motor shaft by hand or with a wrench.
Forcibly turning the motor shaft damages the gear
train and stroke limit contacts.
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.
— Normally Open motors are shipped in the open
position (clockwise, viewed from the power end).
— See Fig. 12 (or the auxiliary switch Instruction
Sheet) for auxiliary switch wiring.
— TRADELINE motors are shipped with auxiliary
switch cams that permit acceptance of 220736A,B
Internal Auxiliary Switch Kits. Refer to form 63-
2228 for kit installation instructions.
To rotate a cam, insert a small screwdriver (1/8 in. or 3 mm
blade) through the wiring 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 wiring 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 wiring box
cover.

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. At this point, the internal motor limit
switch opens, de-energizing the motor. The brake solenoid is
energized, however, and remains so as long as the controller
is closed. The brake holds the motor in the energized position
until the controller opens. At this point, the brake is released
and the spring returns it 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.
