Table 5. Series 90 Modutrol Motor Timing and Torque Ratings.
a
Timings apply to all TRADELINE models. Some OEM models are available with non-standard timing/torque.
b
The torque rating for dual-ended shaft motors is the sum of the shaft torques (power-end torque plus auxiliary-end torque).
c
Breakaway torque is maximum torque available to overcome occasional large loads such as a seized damper or valve.
d
Low timing is for M9184D1005 only.
NOTE: Some 150 lb-in. and 300 lb-in. torque adjustable stroke motors have timings that are twice that of the nominal timing.
IMPORTANT
Never use a Modutrol Motor continuously at the
Breakaway Torque rating.

Mounting
CAUTION
Equipment Damage Hazard.
Can damage the motor beyond repair.
Always install motors with the crankshaft horizontal.
Improper motor mounting can result in inadequate
motor gear train lubrication.
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 1/4 inch (6.4 mm) machine screws or bolts.
• Non-Spring Return Motors are shipped from the factory in
the closed position (at the limit of counterclockwise rotation,
as viewed from the power end of the motor).
• Spring Return Motors are shipped from the factor y in their
normal position:
— Normally closed models: shipped at limit of counter-
clockwise rotation, as viewed from the power end of the
motor.
Adapter Bracket
The 220738A Adapter Bracket, positioned between the motor
and the equipment, raises motor shaft height by 0.75 in.
(19 mm) to match that of the former Modutrol Motor.
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.
To mount the motor with the bracket (See Fig. 3):
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.
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 (See Fig. 4).
Damper Linkages
The motor does not include a crank arm. Order the crank arm,
included in the Q605 Linkage, separately (refer to Accessories
in the Specifications section). For detailed instructions on the
assembly of specific linkages, refer to the instruction sheet
packed with the linkage.
CAUTION
Equipment Damage Hazard.
Stalling a motor can damage the drive shaft.
Ensure installation of motors and linkages allows the
motor to drive through full stroke without obstruction.
Valve Linkages
The Q100 Linkage requires the 220738A Adapter Bracket for all
valve applications . Applica tions with the Q500 1 Valve Linkage
do not require the 220738A Adapter Brac k e t (Refer to Fig. 3).
Junction Box
When used with liquid-tight conduit connectors, the junction
box provides NEMA 3 weather protection for the motor. The
junction box, standard with replacement motors, encloses the
terminals and provides knockouts for wiring conduits. Housing
an internal transformer or internal auxiliary switches requires
use of the junction box.

The motors in the application need to be all symmetrical or all
asymmetrical. The M62 motor needs to be a "-S" slaving
model, as listed in Table 8. In order to get the correct response
the Series 62 needs the appropriate shunt resistor from Table
8. The motors' potentiometer settings are given in the
configuration table (Table 9) below. When slaving more than
one Series 90 motor use the appropriate resistor table as
indicated by the configuration table and install two resistors to
ONE of the motors (Tables 10 and 11). If the motor is the M62
master connect one resistor from terminals T to G and one
from T to Y. If the motor is one of the M90 slaves connect one
resistor from terminals R to B and one from R to W.
NOTE: More than 6 slaves is not recommended.

SETTINGS AND ADJUSTMENTS
Before Setting Stroke
1. Remove the top cover from the motor.
2. Disconnect the controller from the motor.
3. Connect a remote potentiometer to the motor as shown
in Fig. 6 (R-W-B).
The stroke adjustment on the series 2 and series 3 motors is
made using the stroke and sensitivity
potentiometers located
under the cove inside the motor. The stroke adjustment on a
series 1 motor was made by adjusting the CAMS.
For Series 2 and Series 3 Motors:
To set the stroke to 160 degrees (maximum position) turn both
stroke and sensitivity potentiometers fully clockwise ,
using a 1/8 inch straight-blade screwdriver.
To set the stroke to 90 degrees (minimum position) turn both
stroke and sensitivity potentiometers fully counter-clockwise
, using a 1/8 inch straight-blade screwdriver.
To set the stroke between 90 and 160 degrees:
1. Turn the stroke and sensitivity
potentiometers fully
clockwise, using a 1/8 inch straight-blade screwdriver.
2. Turn the remote
potentiometer (previously installed on
R-W-B terminals) to maximum position.
3. Turn the sensiti vi ty potentiometer to the selected stroke
(between 90 and 160 degrees) OR until the motor stops.
4. IF the motor stops before the selected stroke is reached,
turn the stroke

Fig. 10) sets the timing to 1minute, if turned fully CCW , 2
minutes if turned to its middle point and 4 minutes if turned fully
CW .
CAUTION
Careless Installation Hazard.
Use of excessive force while adjusting cams
damages the motor.
To avoid damaging motor end switches, set cams by
moving only the top of the screwdriver.
CAUTION
Careless Installation Hazard.
Forcibly turning the motor shaft damages the gear
train and stroke limit contacts.
Never turn motor shaft manually (either by hand or with
a wrench).
CAUTION
Equipment Damage Hazard.
Can damage the motor beyond repair.
Set cams by moving the top of the screwdriver only.
Pressing screwdriver against cam slot sides or use of
excessive force can damage motor end switches.
Fig. 11. Terminals and Adjustments.
Auxiliary Switches
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°.
Motors with factory-added auxiliary switches are shipped in the
closed position (fully counterclockwise, as viewed from the
power end). Auxiliary cam default actuates the switches 30°
from full open with a 1° differential. With the motor in the closed
(fully counterclockwise) position, the auxiliary switch breaks
contacts R-B. Refer to Fig. 7 (or the auxiliary switch Instruction
Sheet) for auxiliary switch wiring.
NOTE: Auxiliary switches can only be added to motors
that include auxiliary switch cams. (These cams
cannot be field-added.)

NOTE: Series 3 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.
Auxiliary Switch Adjustment
1. Remove the top cover from the motor to gain access to
the motor terminals and auxiliary cams.
2. Disconnect the controller from the motor.
3. Connect a potentiometer to the motor as shown in Fig. 6.
4. Using the potentiometer, drive the motor to the position
where the auxiliary equipment is to be switched.
5. For a 1° switch differential, check continuity of the auxiliary switch contacts R-B and rotate the cam as follows:
a. If the contacts are open, rotate the cam clockwise
until the R-B contacts close.
b. If the contacts are closed, rotate the cam counter-
clockwise until the R-B contacts open.
6. For a 10° switch differential:
a. Spring return models: rotate the cam approximately
180° so that the slow-rise portion of the cam actuates the switch. Then check continuity of the auxiliary
switch contacts R-B.
b. Non-spring return models: check continuity of the
auxiliary switch contacts R-B.
7. Rotate the cam as follows:
a. If the contacts are open, rotate the cam counter-
clockwise until the R-B contacts close.
b. If the contacts are closed, rotate the cam clockwise
until the R-B contacts open.
8. Check for proper auxiliary equipment differential and
switching by driving the motor though the full stroke in
both directions.
9. Disconnect the potentiometer, reconnect the controller,
and replace the motor top cover.
NOTE: Changing the differential from 1° to 10° reverses
the switching action. For example, with a 10° differential, switch contacts R-B make and R-W
break on a counterclockwise (closed) rotation.
With a 1° differential, switch contacts R-W make
and R-B break on a counterclockwise (closed)
rotation.
OPERATION
Use Series 90 Modutrol IV Motors for standard Series 90
operation (See Table 12):
1. Two potentiometers, one in the controller and one in the
motor, along with the motor resistor network, form a
bridge circuit. As long as the value of the controlled
medium remains at the setpoint, the circuit remains balanced and the motor does not run.
2. When the controlled medium value changes, the controller potentiometer wiper moves, unbalancing the bridge
circuit.
3. The imbalance is amplified and the microcontroller then
drives the motor in the direction necessary to correct the
controlled medium change.
4. As the motor shaft rotates, it turns the feedback potentiometer, rebalancing the bridge circuit, stopping the
motor.

CHECKOUT
After the installation and linkage adjustment, check the entire
motor and control hookup. Proper checkout ensures that:
• The motor operates the load (damper or valve) properly.
• The motor responds properly to the controller as the input
varies (See Table 12).
• The auxiliary switch, if used, operates at the desired point of
motor rotation.
1. Inspect motor, linkage, and valv e or damper to ensure all
mechanical connections are correct and secure.
NOTE: In damper installations, the pushrod should not
extend more than a few inches past the ball
joints.
2. Ensure that there is adequate clearance for the linkage
throughout the entire motor stroke without binding or
striking other objects.
3. Ensure the motor transformer is properly sized.
NOTE: If a common transformer is used to power multi-
ple motors, ensure the power input is in phase
with all motors.
4. Drive the motor fully open and fully closed
(See Table 12).
NOTE: Refer to controller or system instructions for
additional checkout procedures.
5. For spring return motors, ensure that the valve or
damper returns to normal position upon power interruption.
6. Return the controller to the desired setting before leaving
the job.
REPLACEMENT
Damper Application
1. Turn off power and remove wiring from the old motor.
2. Remove the crank arm from shaft of old motor and
remove the old motor.
3. Determine necessity of the mounting bracket. If the linkage can reach the new motor shaft position and the
crank arm has clearance for the necessary rotation, the
bracket is not required. Use the 220738A Adapter
Bracket or the 221455A Crank Arm if the crank arm must
rotate through the bottom plane of the motor.
a. If no bracket is required, mount the new motor
directly to the equipment and refer to the Installation,
Settings and Adjustments, and the Operation and
Checkout sections of these instructions.
b. If the bracket is required, refer to the Adapter Bracket
section and Fig. 3 in addition to the Installation, Settings and Adjustments, and the Operation and
Checkout sections of these instructions.
4. Use No. 12 or 1/4 inch machine screws or bolts to mount
the new motor.
5. Mount damper crank arm and linkage to the new motor
shaft.
6. Use the Checkout procedures to test the crank arm and
linkage adjustment.
Valve Application
When replacing a motor in a valve application, the linkage
determines the necessity of the 220738A Adapter Bracket.
With Q100, Q601 or Q618 Linkages, it is necessary to use the
220738A to raise the motor shaft to the appropriate height.
Valve applications with a Q5001 Lin kage do not require the
220738A Adapter Bracket. To operate Honeywell V5011
two-way or V5013 three-way valves through full stroke, use a
160° stroke motor or make sure the stroke is adjusted to 160
degrees.
