INSTALLATION

WHEN INSTALLING THIS PRODUCT...
1. Read these instructions carefully. Failure to follow
them could damage the product or cause a hazardous
condition.
2. Check the ratings given in the instructions and on
the product to make sure the product is suitable for your
application.
3. Installer must be a trained, experienced service
technician.
4. After installation is complete, check out product
operation as provided in these instructions.
CAUTION
1. Disconnect power supply before beginning
installation to prevent electrical shock and
equipment damage.
2. Never turn the motor shaft by hand or with a
wrench—this will damage the motor.
3. Always conduct a thorough checkout when
installation is complete.
LOCATION
Install the Modutrol Motor in any location except where
acid fumes or other deteriorating vapors might attack the
metal parts, or in atmospheres of escaping gas or explosive
vapors. Motors are rated for ambient temperatures between
-40°F [-40°C] and 150°F [ 66°C].
Allow enough clearance for installing accessories and
servicing the motor when selecting a location (see Fig. 1).
When mounting the motor outdoors in an upright position,
useliquid-tightconduit connectorsand wiringboxto provide
NEMA 3 weather protection. When mounting the motor
outdoors in other than an upright position, use the 4074ERU
Weatherproofing Kit and liquid tight conduit connectors to
provide NEMA 3 weather protection.
MOUNTING
Always install motors with the crankshaft horizontal.
Mountingflangesextending from thebottomof the motor
housing are drilled for 1/4 inch [6.4mm] machine screws
or bolts.
M7161A,B; M7164A,B and M7184A Motors are ship-
ped from the factory in the closed position (at the limit of
counterclockwise rotation as viewed from the power end of
the motor). M7161G and M7164G are shipped in the open
position(atthelimit of clockwiserotationasviewed from the
power end of the motor). See Fig. 2.
ADAPTER BRACKET
The 220738A Adapter Bracket, positioned between the
motor and the equipment, raises the shaft height of the
motor by 0.75 inch to match that of the M734 and M744
Motors. This is required on all valve linkage applications,
Q607 External Auxiliary Switch applications, and on some
Installation
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, with the bolts pro-
vided, through the threaded holes in the bracket. See Fig. 3.
For valve linkage applications, see Fig. 4, the bracket should
first be mounted to the linkage so the bracket can provide a
convenient base for positioning the motor. After the motor
shaft is aligned, it can then be attached to the bracket with the
four bolts provided. The bolts are inserted through the inner
set of slots on the motor flange and into the threaded holes of
the bracket.
DAMPER LINKAGES
A 220738A Mounting Bracket is packed with replace-
ment motors. Using this bracket is optional for many
damper applications. The bracket 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 must be ad-
justed 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 instructions 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 while the motor moves
through its full stroke.
2. With modulating control, maximum damper opening
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.
4. Do not exceed the motor ratings in any installation.
5. Do not turn motor shaft manually or with a wrench—
this will damage the motor.

bolts. The motor is then mounted to the bracket using the bolts provided that thread into the bracket holes.

Refer to instructions packed with each linkage for detailed
assembly instructions. The 220738A Mounting Bracket is
not required for the Q5001 Linkage.
WIRING
Disconnectpowersupply beforewiring topreventelectri-
cal shock or equipment damage. All wiring must agree with
applicable codes, ordinances, and regulations.
Make sure that the voltage and frequency stamped on the
motor correspond to the characteristics of the power supply.
See Figs. 6-7 for typical system wiring.
Make certain that the voltage and frequency stamped on
the transformer correspond to the characteristics of the
power supply.
The motor terminals are quick-connects located on top of
theprintedcircuitboard shown in Fig.5.Accessto the wiring
compartment is gained by removing the four screws on the
top of the wiring box and lifting off the cover.
AUXILIARY SWITCH
The auxiliary switch in the M7161B and M7164B is an
spdt switch that is actuated by an adjustable cam. The cam
is factory-mounted on the motor shaft at the power end of
the motor. The setting of the cam determines the point in the
motor shaft rotation at which the auxiliary equipment will
be switched on or off. Auxiliary switch wiring is shown in
Fig. 8.

(Fig. 9)
CAUTION
1. Live circuits are exposed during the auxiliary
switch adjustment procedure. Always turn off
power before adjusting switch cams.
2. Do not turn motor shaft by hand or with
wrench as damage to the motor can result.
NOTE: The following instructions are for normally closed
motors (motor shaft rotates clockwise , as
viewed from the power end of the motor, on an increase
in signal).
1. Remove cover of wiring box.
2. Run motor to fully closed position.
3. Determineamountofshaftrotation,indegrees,desired
before switch is energized.
4. Turn off power. Note position of cam slots:
a. If 10°differential is desired, rotate the cam with
screwdriver to the desired position for switch
action.
b. If 1°differential is desired, rotate the cam ap-
proximately 180°with screwdriver, then rotate to
desired position for switch action.
NOTE: Each division on the cam represents 15°of motor
rotation. Therefore, if 60°of motor rotation is desired
before switch operates, rotate the cam four divisions from
the reference point.
5. Connectauxiliary equipmenttoauxiliaryswitchleads.
See Wiring section.
6. Turn on power and check for proper switch differen-
tial and switching of auxiliary equipment by driving the
motor through full stroke in both directions. If necessary, re-
peat steps 4 and 6 until correct switching action is obtained.
7. Replace cover of wiring box.
CAUTION
Before servicing, disconnect all power supplies
to de-energize the auxiliary switches.

Operation and Replacement
OPERATION
The M7161, M7164 and M7184 Motors operate in
response to a dc voltage input signal to terminals C and R,
positioning a valve or damper at any position between fully
open and fully closed. The input signal causes the modified
dc bridge circuit in the motor to become unbalanced. The
small signal resulting from the bridge unbalance is ampli-
fiedand energizes1 of2triacstorunthemotor.Asthemotor
runs, a feedback potentiometer driven by the motor moves
to rebalance the bridge. When the bridge is balanced, the
motor stops.

After installation and linkage adjustment, operate the
motor through the thermostat or panel. Make sure that:
• The motor operates the damper or valve properly.
• Themotorrespondsproperlyasinputvoltage isvaried.
• The auxiliary switch, if used, operates at the desired
point of motor rotation.
Inspectthemotor,linkage, and valve or dampertoseethat
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. See System Instructions for
additional checkout procedures.
