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.

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.
