SERIES 90 MODUTROL IV™ MOTORS

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
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 no bracket is used in replacement applications,
damper linkages require adjustment for the new shaft position.
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

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. See Fig. 8 (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.)
TRADELINE motors are shipped with auxiliary switch cams that permit acceptance of 220736A,B Internal Auxiliary Switch Kits. Refer to form 63-2228 for 220736A,B installation instructions.

SERIES 90 MODUTROL IV™ MOTORS
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. 7.
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
counterclockwise 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
counterclockwise 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 6):
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 energizes switching to
drive 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 6.
• 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
multiple motors, ensure the power input is in phase with all motors.
4. Drive the motor fully open and fully closed. See Table 6.
NOTE: Refer to controller or system instructions for
additional checkout procedures.

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.
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.

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 two­way or V5013 three-way valves through full stroke, use a 160° stroke motor.
