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 counterclock-
wise 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.
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. 63-2228 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.
OPERATION
Use Series 90 Modutrol IV Motors for standard Series 90
operation (See Table 7):
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.

MOTORS
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 7).
• The auxiliary switch, if used, operates at the desired point
of motor rotation.
1. Inspect motor, linkage, and valve 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 mul-
tiple motors, ensure the power input is in
phase with all motors.
4. Drive the motor fully open and fully closed
(See Table 7).
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 Linkage 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.
